As Nokia CEO in 1992, Ollila in ten years time, Nokia the Finnish industrial group from a difficult build to become the world s largest smartphone maker, the market value of 650 million euros (about $ 850 million) jumped to 300 billion euros.

But from 2008 onwards, the company once again in trouble have not been able make a difference in the smart phone market. Not only face competition from Apple and Samsung in the high-end market is still low-end market suffered the blocking of the Asian manufacturers.

Samsung last month, has become the world s largest smartphone maker, ending 14 years of dominance in Nokia. Ollila acknowledged that Nokia in the smartphone revolution too slow in responding, although the company back in 2006, has been found that this important trend. But he also said that a combination of new products and services will reverse the situation, the company s new products will take full advantage of the opportunity.Film Blowing Machine

"The Tablet PC is important, so we will focus on this market will have a different mixture of different forms." Ollila said.

The Ollila Stephen Elop (Stephen Elop) and Microsoft co-production of smart phones decision Elop served as a strategic decision since Nokia CEO. However, Nokia s Windows Phone mobile phone has mediocre and failed to pose a threat to the dominant position of Apple and Samsung.

But Ollila said: "I am very satisfied with the status quo if the competitors are very strong, it will take some time."

air compressor parts – China Manufacturer
Thank you for inquiry my air compressor parts, Tel:0086-577-86910011, Email:jdyo@yuan-ou.com
http://www.aircompressor-parts.net/

China is one of the fastest growing countries in the world s industrial development, air compressor manufacturing is irreplaceable; as long as the industry still exist, the market share of the industry is still developing the air compressor will never drop, provide technical machinery manufacturing equipment can not be replaced. With the acceleration of the scientific and technological progress in recent years in the air compressor field of new technologies, new materials, new equipment, and other emerging, but they are around the industry to improve the technical content, and reduce production costs, improve economic efficiency and productivity, etc. appear. Centrifugal compressor valve moving parts and simple, and low manufacturing precision, so their manufacturing costs are relatively low and high reliability. Due to the impact of screw compressor valves and absorption chillers, centrifugal refrigeration compressor valve development is relatively slow. Under current technical conditions, the centrifugal refrigeration compressor valve is mainly used for air conditioning in large buildings, the demand for less. In recent years, due to large infrastructure projects have been started, centrifugal refrigeration compressor valve has become the focus of attention.
In the power sector, piston compressor valves occupy the main market. With the improvement of people s use of the environment and energy consumption, environmental protection requirements, screw and scroll air compressor valve began to occupy a certain market. In the field of refrigeration air compressor, reciprocating refrigeration compressor valve as a traditional refrigeration compressor valve, applicable within the broader context of the cooling capacity of refrigeration system. Its application is still relatively wide, but the market share is gradually reduced.air compressor parts
The rolling rotor compressor valves are widely used in home air compressor, there is a certain application in the refrigerator soil. Compressor valve does not require suction valve so that it applies to variable-speed operation, which can improve system performance through frequency control.
The rotary vane compressor valve is mainly used to provide compressed air, the exhaust is generally 0.3 ~ 3m3/min, lower market share.
The scroll compressor valve in the past decade has been rapid development, constitutes a new bright spot of the compressor valve technology development. Disaster rotary compressor valve has an absolute advantage in the field of cabinet air compressor.
Screw compressor valve screw compressor valve has a small size, light weight, easy to maintain, is the rapid development of a refrigeration compressor valve models. At present, the screw compressor valve is mainly used in compressed air and medium-sized refrigeration heat pump air compressor system. Due to the continuous improvement of the screw compressor valve reliability, so that within the range of the secondary cooling capacity has been a gradual replacement of reciprocating compressor valves, and occupy part of the centrifugal compressor valve market. User geographical distribution is mainly based on geographical division, usually the number of development resources were probably the statistics, in east China s enterprises are concentrated, and the number of enterprises but also in other places can not be compared. Jiangsu, Zhejiang area is the battleground of the air compressor industry, not foreign brands alone, Jiangsu, Zhejiang and local air compressor manufacturers, and have a certain reputation in the market.
But I believe that after the Central South region will increase, central China factory is also a step-by-step increase, the Mainland s economy has slowly, I believe that before long, the central and southern China air compressor users will increase. From the statistical data, the proportion of the use of the machinery industry accounted for, it should be no doubt, chemical, petrochemical, power industry, the demand for air compressor is also relatively large, some other industries, or less. In fact, the air compressor is a relatively basic equipment, general plant needs, just different for gas consumption. There is one other occupied by the share is still relatively large, may be some of the construction industry or other industries, it may be some emerging industries. For the machinery industry is relatively concentrated, I believe it should be the most competitive incentives of the air compressor industry. But not necessarily, and now the air compressor plant competition has been heating up the powerful, each region of the air compressor vendors can only say that the machinery industry and chemical industry, these two relatively large demand for the air compressor Elsewhere, competition is even more incentive.compressor valves
This figure is I want to draw on other sites, we can say is more convincing. Cost, reliability, durability, energy consumption, service is the most important enterprises in the procurement of air compressor, several decision-making factors. And the impact factor of the brand is not very high, this may be unexpected, reliability, how should I say, very often, for the air compressor is not very understanding, more understanding through the clerk mouth, so it feels a lot when brand affect reliability. As we buy shoes, a brand of shoes, there is always unreliable, brand shoes, especially shoes brand loud, you ll find the very reliable, even if your price does not matter.
In fact, the inside of these factors, a lot of things are interdependent, such as brand impact to the reliability, energy consumption also affected the cost. So, in roughly the same product, products, service, business skills, the brand for the user decision-making should play a small role. Of course, we can not ignore the image above did not mention a factor that is the price.

At present, most of the pumping well at home and abroad is a tube pump. Tube pump valve is a one-way well in the process of pumping crude oil from the formation through the fixed valve into the pump and discharge the ground. The process of pumping oil wells of liquid through the fixed valve, on the one hand, the liquid contains impurities, prop fixed valve can not be restored in situ, will be always in the open state; the other hand, the liquid through the fixed valve into the pump, due to wear or erosion of the liquid will cause the fixed valve failure. If the fixed valve single fixed valve pump does not work, then you need to be aperiodic oil well pump check operations.
Solve this problem, the researchers of the Tuha Petroleum Exploration and Development Headquarters, downhole technology jobs with the State of Georgia 12 blocks oilfield workshop jointly pilot study, the single fixed valve of the pump be used for two fixed valve, is the fishing style pairs of fixed-valve pump. This pump has achieved good results in the application of the State of Georgia 12 blocks oilfield.
Technical Analysis
A structureStainless steel tee
Pairs of fixed-valve structure of the pump is increased on the basis of the ordinary pump may be fishing for fixed valve and fixed valve salvage. Fishing fixed valve and salvage from top to bottom in order to salvage the claw (through the thread and the pump piston to connect) and salvage the head and fishing-style fixed valve (threaded connection), retainer, adapter, two ring can be fishing for a fixed valve cover, valve ball, tee and pressure cap.
Cylindrical salvage claw 2 in the opposite direction of the hook groove salvage head welding a cylindrical bar, hook slot width slightly larger than the diameter of the bar, the bar to enter or disengage the hook slot can be realized to salvage claw and salvage the connection or separation of the head.
2 Work
Fixed fishing-type valve by artificial hanging in the salvage claw, transported by the pump piston to support a short section of the upper position, and then load the 419 ~ 918,2 two sealing gasket gently through the rim due to the role of compression (with chamfer on the 60b, 30b chamfer), sealed with sealing gasket and support short section, when the valve at the top of the retainer at the same time into supporting a short section of the retainer contraction and sitting firmly support short section, in the work body not up, pump Wheel prop retainer on the valve body, the body can not downstream, both in order to achieve a seal. When the ride to win the title of a fixed valve lever on the column to the original hanging weight, rotation is 1-2 laps, salvage head to go to the vertical position of the slot from the suspension of the salvage claw, to mention salvage the head to the salvage claw from salvage header off open, a good anti-red from the start pumping can be fishing for fixed valve to work.
Should be based on the well pump check indicator diagram to determine the site of pump failure, if the fixed valve failure, should deepen the rod string, reverse lever column 1 or 2 laps, when the salvage salvage claw Laozhu the salvage head salvage a fixed valve (reverse salvage process, the operator should carefully observe the displacement of the rod string changes during rotation, the rod moves down, you should immediately stop the rotation, proved to salvage success. by careful observation , both to ensure the success of the salvage, but also to prevent the cause anti-torque effect), maintenance or replacement of the valve under the re-entry wells. If the parts above the fixed valve failure is only the piston replacing failed attachments, but if the work of the wells to pump inspection cycle, you must after all since the pump inspection.Pipe Fittings
3 The main technical parameters
4 features
(1) can be fishing for a fixed valve reliable, its body sitting firmly support in the short section, pump steel rings supporting the body of the retainer, the body can not up and down movement of the work process, so not only does not damage the body, and can ensure the normal production of the wells.
(2) of the valve by the piston pump delivered to the packer position, the valve packer, dispose of, transfer of good data, open the pump work. Pump installed in the field without removing the valve easy to use, non-repetitive processes.
(3) in the pumping process, contains dirt or wear and erosion of the role of the valve within the liquid, causing the valve is not working properly, reducing the efficiency of the pump that the pump check operations. Can fishing-fixed valve is installed to avoid the defect of not working properly due to a fixed valve failure caused by the pump, greatly reduces the operating costs.
(4) use of the fixed valve can fishing, simple maintenance, and generally just replace the rubber seals and the ball can then, few replacement parts, repair rate.
Field ApplicationStainless steel Pipe Fittings
Fishing style fixed piston pump from the July 2002 application to the current construction of 85 wells in the Georgian National Oil Field 12 blocks. 1 well before the next pump tubing over regulation, so that the pumps meet resistance, resulting in pump damage in the working process, which has a success rate of 99% of the fixed valve packer and salvage reliable and convenient. In the construction process of these wells are one-time success. Before the pump is a single fixed valve in the pumping process, as long as the fixed valve problems you need to pump inspection. The improved pump a fishing fixed valve in the working process, the fixed valve in the tubing can not afford to replace. Thus, on the one hand extend the cycle of the pump check the other hand, savings in operating costs. Statistics, so far, the construction of 85 wells, with an average per well check period extended for 018 times, saving jobs and other costs of approximately 175.18 million yuan. (1) fishing double fixed valve pump, to ensure that the pump in the pit safe and reliable. (2) the operation of the pump process is simple, the construction of a high success rate. Maintenance, replacement parts, repair rate

As of the end of November 2006, the Karamay Oilfield heavy oil company statistics wells planned shut-in number accounted for 32.5% of the total number of open wells of the well, the actual utilization of heavy oil wells, which means heavy oil company has considerable "capital" is idle. Formation of shut-in are many reasons, mainly due to high moisture content of the serious casing deformation, the development of poor and low-, low-yielding liquid, sand card pumps and other factors of which six – nine blocks of heavy oil company out of the sand in serious condition, leading to sand card pump wells accounted for 26% of the block. How to make these serious sand wells to maintain the normal production of heavy oil company s top priority. In order to better resolve the sand well sand card buried by sand the plunger phenomenon, heavy oil, six – nine blocks chosen Anton Oilfield Services (Group) Co., Ltd. developed AOC special alloy sand pump to carry out field trials.
For the lack of material of the surface of the pump barrel and backward surface treatment process, the oil of Anton developed with independent intellectual property rights of the AOC-165C alloy powder and the inner surface of spray technology to prepare AOC alloy coating with a thickness greater than 0.25mm, -micron carbide particles dispersed in the coating. This metallurgical bonding force AOC alloy coating with Super Abrasive and corrosion resistance.
Match on the basis of innovation in the pump barrel coating after abrasion resistance test, preferably a nickel-based alloy spray plunger. This configuration enables the pump barrel and plunger Abrasive wear and corrosion resistance can be greatly improved anti-wear test to prove that life is three times the ordinary pump tube, the plunger.stainless steel pipe fittings
The lining of the valve cover selection of independent intellectual property rights of Anton oil AOC-150C alloy powder as a coating, impact resistance, excellent abrasion resistance. Ball valve with integrally cast made of special carbide finishing a density of 2 times the ordinary ball, have the adaptability to the high viscosity of crude oil, strong wear and corrosion of underground meson.
Long short plunger pump tube structure, both ends of the pump barrel with automatic adjustment of scraping sand ring, in the reciprocating motion of the plunger, there is always part of the plunger in the pump barrel outside, the sand is not easy to enter the plunger and pump barrel gap, the eradication of the sand buried the plunger, and has the advantages of small downstream resistance. The crowd Road valves and streamlined channel design to reduce the resistance of the oil inlet, to improve the full coefficient of the pump, but also to avoid the deposition of sand in the barrel of the work. Clever grit channels to ensure that the well produced fluid sinking sand slipped smoothly into the grit under the pump tube, to avoid the occurrence of sand buried the plunger and the card pump stopped pumping.
This sand pump for handling sand in heavy oil steam, corrosion well and dilute the oil out of sand, corrosion well, 7% -10% of the sand content of the produced fluid, sand particle size of 0.01-3.0mm, the maximum well temperature of 150 ℃.stainless steel clamps
Reservoir average of six – nine blocks of the heavy oil company central burial depth of 260m, effective reservoir thickness of 5-20m, penetration average 2μm2, ground tank oil viscosity crude oil density the 0.92-0.96g/cm3, 20 ° C in the 15 000-105mPa.s steam throughput of oil production. Reservoir lithology of muddy cement gray – gray-brown fine sandstone, cemented loose, remove the cores in the reservoir area and nearly all of the loose sand. Out of the sand sample analysis according to workover grit diameter in the 0.71-0.125mm, sand the main component of quartz, feldspar, lithic. According to the analysis of the crude oil sand production wellhead samples, more than 50% of wells oil carrying sand, where sand particle size of 0.01-0.05mm, the number of wells is about 88%, sand particle size of 0.05-0.10mm number of wells is about 4%, sand particle size greater than the the 0.10mm wells about 8%. Due to the smaller particle size of sand, fine sand can easily be oil flow carrying into the pump barrel caused by the downhole pump pump cards, affecting the normal production of oil wells.
AOC special alloy sand pump 10 wells in the field application of heavy oil company, is mainly used in heavy oil steam throughput out of the sand wells, a 12% increase in the average efficiency of the pump than ever before; cumulative oil 2769 side. Which saved 8 due to frequent sand card but can not be the production of oil wells; 65009 Well check pump cycle has been to extend the 130 days, and continue normal production, the effect is remarkable; 65 457 wells out of sand serious, frequent card pump, pump inspection cycle less than 31 days. daily fluid production of 1.9 tons, daily oil production of 0.3 tons, 4.5 tons, the use of of Anton special alloy pump, Nissan fluid, daily oil production of 1.0 tons, has been extended 89 days of the check period is still in production. AOC special alloy sand pump from investment in the field test has been no case of sand card, corrosion caused by workover operations.sanitary fittings
Anton oil AOC special alloy sand pump to high-quality new materials leading to similar domestic products, and has a long plunger short pump barrel, scraping sand bodies, the crowd Road valves, grit channel optimized design in the company of heavy oil The application made other anti-sand pump can not achieve good results, fully able to meet the requirements of the serious heavy oil sand production wells pumping oil production

, chemical, gas, electricity, metallurgy, as long as, construction, water supply and other industries will be used in safety valve. Thus, the purpose of the safety valve is wide, but, before that, we must first understand the safety valve can better use. Below, a brief look at the safety valve. The safety valve is a boiler, pressure vessel and the other by the pressure equipment safety accessories, operating reliability and performance quality will be directly related to the equipment and personal safety of users. At present, the mass production of the safety valve is a spring applied and leveraged two major categories. Spring-loaded safety valve is divided into closed and not closed, generally flammable, explosive or toxic media should be used in closed, steam or inert gas may choose not closed. Leveraged safety valve selection, if the temperature is high the best selection of safety valve with a radiator. Grasp the safety valve selection techniques is also very necessary. Generally determined by the operating pressure of the nominal pressure of safety valve, safety valve temperature range, determined by the operating temperature determined by the calculated safety valve set pressure value set pressure range of spring or a lever, and then determine the material of the safety valve in accordance with applicable media and structure type, calculated according to the safety valve Discharge valve throat diameter. Hot water boilers generally is not closed with the wrench Weiqi safety valve. The steam boiler or steam pipe generally is not closed with a wrench a safety valve. Water and other liquids are incompressible media in general with closed Weiqi safety valve, high pressure water supply for general use closed a safety valve, gas compression medium for general use closed safety valve. Large diameter, large displacement and high pressure systems typically use pulse valve. Tanker train car transportation of liquefied gas tankers, tanks and other general use built-in safety valve. Tank top general, the hydraulic valve need to be used in conjunction with the Safety Act. Underground water or gas pipelines generally use pilot operated relief valve. General with the safety valve on the LPG station can pump the liquid return pipe. Negative pressure or operating process may produce a negative pressure systems generally use vacuum relief valve. Backpressure volatile and toxic and flammable container or piping systems are generally used bellows safety valve. Medium solidification point lower system generally used in thermal insulation jacket safety valve. When the safety valve fails, eliminate failure to become familiar with the. First, we must first distinguish between the safety valve exactly what type of failure. Followed depending on the failure to use a different method to dispel. The most common faults are: the emissions from the valve seat, and leaked to the required pressure without opening the exhaust back pressure continues to rise, the valve flap frequency hopping or vibration, less than the required pressure open. Emissions after the valve is not set to the back seat is spring bent stem, install the valve malposition or stuck cause should be re-assembly; when a leak occurs, this may be due to the valves and valve seat sealing surface between dirt can be used to enhance the wrench to open the valve several times, rushed to the dirt, if the sealing surface damage should be based on the extent of the damage, have it repaired by grinding after grinding or turning, curved stem, tilt lever and fulcrum deflection caused by the spool and the valve flap dislocation, should be re-fitted or replaced; not open to the required pressure is constant pressure allowed, should be re-adjusted the location of the compression spring or weights; encountered in exhaust back pressure the situation continues to rise, should be re-selection of a suitable safety valve if the valve is not open to the proper height or exhaust pipe cut-off is not enough, the stem should be re-assembly or replace the spring or take the safe discharge area of ??the exhaust pipe; valve flap frequency jump or vibration spring stiffness is too large, it should use the appropriate stiffness of the spring, if it is because improper adjustment of the adjustment ring back seat pressure is too high, you should re-adjust the position of the adjustment ring encounter too large due to the discharge piping resistance caused by emissions of back pressure, reduce the discharge pipe resistance; less than the required pressure to open more constant pressure aging elastic denial or spring decline, should be properly tighten the adjustment screw or replace the spring. Concept in the process of identifying a safety valve, only familiar with the safety valve in order to distinguish the use of safety valve, so that the face of failure will find the right way, which means that this process is like a bond, one can not . Above, is the necessary knowledge of the application of safety valve.

Environmental protection and energy conservation are the two main themes of today\\ s social development. Business enterprises or individuals, based on the pursuit of individual profit maximization, the pursuit of efficiency, reduce energy consumption into the common consciousness.
     Characteristics of the new clothing Dryer device transformation: the finer the material, uniformity of better logistics, smaller trend, system lag, small-scale, heated area, the higher the evaporation intensity. The large particle group is in the contrast material, easy to form a thin film hard gas, the internal material to prevent heat and mass transfer. Therefore, when the dry clay or shale, crushing the material should be dealt with. Viscosity, high wet clay, fracture is a difficult problem. The most prominent Qian southwest, south China, mainly in the Northeast. Almost all of the clothing dryer feed chute tilt. High temperature, load changes, gas heat chute erosion, oxidation, deformation damage is very serious, the replacement will be a lot of trouble. More severe bending of the chute firing often take advantage of the damping ring of the roof or dryer, resulting in leakage leakage, which will greatly reduce the thermal efficiency and life of the dryer. Whether it is made of steel or cast iron ducts, not a good solution to its short life. In order to extend the life feeding tube, drying machine, can dump slot \"straight pipe tanks + board\" of in the under and upper straight tube, the assembly straight into the furnace wall to avoid the high temperature oxidation and hot gas erosion; lower from the material straight down ramp plate convergence, and then slipped into the dry material along the slope. Slide plate of refractory cast iron plate, following by the bricks rise driven.
    Current models and specifications of the dryer, the material, the price of the Crusher of the same. Dryer selection become a people\\ s problems. Select the right drying function to save the investment, reduce operating costs, ensure product quality, and maximize the economic benefits. Dryer ideal selection must be based on the user\\ s own conditions and material factors, focused to find the most suitable material models. The following are the general principles of the dryer equipment selection:
    , Selection is best to make the material dry experiment, in-depth understanding of the drying device of similar materials have been used, often the appropriate selection. Applicability.
    Second, the preferred simple structure, an adequate supply of spare parts, high reliability, long life and the drying device.
    , Clothing dryer dryer equipment, must be able to apply to specific materials, and meet the material dry use requirements, including the materials handling well, and can meet the processing capacity, dehydration, product quality and other aspects of basic requirements.
    Fourth, low running costs. Sand and gravel production equipment depreciation, operating costs of energy consumption, labor costs, maintenance costs, spare parts, etc. to be as low as possible.
    Five low energy consumption. Different drying methods, the energy consumption indicators and conduction dry thermal efficiency is theoretically up to 100%, convection drying only about 70%.
    6, in line with the requirements of environmental protection, safe working conditions.
    Seven, saving investment. Completion of the drying device of the same functions and sometimes mineral processing equipment cost disparities should choose the lower of selection.
    Drying rate. The drying rate alone, look at convection drying material is highly dispersed in the hot air, the critical moisture content is low, fast-drying, and with convection drying, different critical moisture content of the drying methods are also different, and thus the drying rate.

1, LED street light its own characteristics – light one-way, there is no diffusion of light to ensure that light efficiency. LED street lamp has a unique optical design, LED street light shines on the required area lighting, and further improve the light efficiency, in order to save energy. 3, the efficiency of the LED light source and currently has 110-130lm / W, but there is still much room for development, the theoretical value of 250lm / W. The luminous efficiency of high pressure sodium lamp increase only with the power increase, therefore, the overall luminous efficiency LED lights than high pressure sodium; (the overall light efficiency is the theoretical power LED street lamp advantages
Actually 250W high pressure sodium light efficiency than LEDs). 4, the light color of the LED lights than high pressure sodium high many, high pressure sodium lamp color rendering index is only 23 or so, while the LED street lamp color rendering index to reach 75 above, from the perspective of visual psychology to consider, to achieve the same brightness, LED lights light degrees average can more than 20% lower than the high pressure sodium (United Kingdom truth lighting standards). 5, LED street light a small decline, the light fades less than 3% a year, for 10 years to reach the road using the illumination requirements, high pressure sodium lights and feeble, has fallen more than 30 percent a year or so, so, LED lights on the design of the use of power can be low than high pressure sodium lamp. 6, the LED lights automatically control energy-saving devices, to achieve the maximum possible in the case meet the requirements of the different times of illumination to reduce the power to save energy. Spark intelligent LED lamps can achieve computer dimming control of the sub-period of time, light control, temperature control, remote control, automatic inspection and other features of human nature. 7, the LED is low voltage, voltage safe voltage to drive a single LED, single LED power products for 1 watt, so it is safer than the use of high voltage power supply, especially in a public place (for example: street lighting, factories, mines and lighting, automotive lighting, commercial lighting, etc.). 8 LED small piece of each unit is only a small volume, so the device can be fabricated into various shapes, and is suitable for variable environment. 9, long life: 50,000 hours or more, a three-year quality assurance. Inadequacies in the life of the power supply is not guaranteed. 10, High luminous efficiency: ≥ 100LM chip, compared to traditional high pressure sodium lamp more than 75% of the energy-saving. 11, easy to install: no need to Jiamai cable without the need rectifier directly to the street light installed at the poles connected or nested to light the original lamp shell. 12, the thermal control is excellent: summer temperature was controlled at 45 degrees, and passive cooling, lack of summer heat protection. 13, the quality is reliable: the circuit power supply used in all high-quality components, each LED has a separate over-current protection, do not have to worry about damage. 14, light color uniform: without the lens, do not sacrifice in order to improve the brightness and uniform light color, thus ensuring the aperture light color uniform. 15, the LED does not contain toxic metals mercury, unlike the high pressure sodium or metal halide lamp on the environment at end of life hazard. The principle of high-power LED street lamp energy saving effect is remarkable, instead of the high-pressure sodium lamp can save 60% or more. (To be known) low maintenance costs: very low maintenance costs compared to traditional lights, LED lights, after less than six years to recover all input costs.
