Ten reasons for the common failure of automobile oil pump （1)The plunger and plunger sleeve are worn。In the process of use，The mechanical impurities in the fuel enter the injection pump cavity，Formation of abrasive wear，Plus the corrosive effects of fuel oil，The gap between the plunger and the sleeve is increased，Fuel leakage from plunger sleeve gap during oil pressure stroke，Undersupply or no fuel。 （2)The oil delivery valve is worn。Mechanical impurities in fuel oil，The high speed flow creates an oil outlet valve、Loose seal due to wear of relief belt or valve seat，The residual pressure in the high-pressure tubing is insufficient。When the injection pump pumps oil again，There is insufficient pressure in the high pressure pipe of some fuel supplement，As a result, insufficient fuel is supplied to the cylinder，No oil supply in severe cases。
Norman building nut and root A nut is a nut，A part screwed together with a bolt or screw for fastening，All manufacturing machinery must use a component depending on the material，Split into carbon steel、Stainless steel、Non-ferrous metal（cupric）And so on several types。Root mother，It is a connecting pipe，Used for locking through wire connectors or other pipe fittings，Other names：Lock nut、Lock nut、A surname。
Xiangtuo synchronous pulley factory The synchronous belt is made of steel wire rope or glass fiber as a strong layer，A circular tape covered with polyurethane or neoprene，The inner circumference of the band is toothed，Make it mesh with the toothed pulley。With the development of The Times, the industrial production capacity is improved，The automated parts industry has also developed。If you want to buy Xiangtuo synchronous pulley you can buy on Feng Ye manufacturers。
Xiangtuo polyurethane synchronous belt polyurethanePUThe synchronous belt is made of imported thermoplastic polyurethane material，It has high resistance to wear，Various types of steel wire core ensure that it still maintains good movement ability in the transmission，Small production tolerance。Production process at the tooth surface and/Or the back of the tooth with a layer of nylon to ensure that the special characteristics of operation in special applications unchanged，A thick layer of polyurethane can also be added to the back of the belt to prevent corrosion or high load。The characteristics of the sync belt are the same，The following Xiaobian will take you to understand the characteristics of Xiangtuo polyurethane synchronous belt：
Guide rail manufacturer With the development of automation industry，The guide rail has also become one of the indispensable parts of automation，Among them, the guide rails sold by their home in Fengye Mall are original and authentic，If you want to buy it, you can buy it at their house。Here is a small series to take you to understand the type of guide rail：
Double strength cylinder popular name is called series cylinder，In fact, it is more appropriate to call it multiple output cylinder（Short for double force cylinder）。 Multiple output cylinders--Use the same and same stressors，The output is the same cylinderSeveral times of，Great contribution，Multilayer piston coupling，The output is multiplied，Compact length dimensions，Multilayer stack，Multiple piston forces at the same time，Multiply the output force of the cylinder。Multilayer booster cylinder：Inside each layer of cylinder，They all have a piston，But the force on the piston during the push and pull，non-equivalence。If thrust is required to work，The piston rod is pushed out，All pistons produce thrust；On return，Only one piston pulls。If you need pull work，When the piston rod pulls back，All pistons are pulling；At launch，Only one piston produces thrust。

one、Precautions for use: 1. Do not touch the sliding seat during product operation and maintain a safe working range。 2. Ball screwWhen the product is used vertically【Zshaft】In order to prevent items from falling, it is recommended that the motor be equipped with a brake device；Gear belt drives are not recommended for vertical use【Zshaft】。 3. Resonance may occur when the effective stroke is too large，The greater the travel, the greater the speed should be reduced。 two、oiling: 1) Lubrication is essential when using linear module slides，If not fully lubricated，The friction resistance during operation will increase and may become the main reason for shortening the product life，The lubrication methods are roughly divided into manual lubrication and automatic forced lubrication，Depending on the operating speed of the system’Use the environment and other requirements to make appropriate choices 2) The frequency of lubricating oil feeding varies according to the conditions of use and the environment，General situati
Double salient pole permanent magnet motor(Doublysalientpermanentmagnetmotor,For shortDSPM)With the rapid development of power electronics and microelectronics90A new type of mechatronics controllable AC speed regulation system has just appeared[1～6]。The system consists of double salient pole permanent magnet motors、Power converter、Position sensor and controller are composed of four parts。Electric machineThe structure of fixed rotor is similar to that of switched reluctance motor,It has a double convex pole structure,But its in the rotor(OR-stator)A permanent magnet is placed on it,Therefore, the operation principle and control strategy are fundamentally different from switched reluctance motor。DSPMThe main advantage of the system is its simple structure、Flexible control、Fast dynamic response、Good speed control performance、torque/High current ratio,Various torque requirements can be achieved/Speed characteristic,Power factor is close to1,High efficiency,It is a new research direction after switched reluctanc
“Alternating current motor”：It is a machine used to realize the mutual conversion of mechanical energy and AC electric energy。Due to the tremendous development of AC power systems，Ac motor has become a commonly used motor。Alternating current motorCompared with DC motor，Because there is no commutator（See commutation of DC motors），So the structure is simple，Easy to manufacture，Relatively firm，Easy to make high RPM、High voltage、Heavy current、Large capacity motor。Ac motor power covers a large range，From a few watts to hundreds of thousands of kilowatts、Even millions of kilowatts。20century80Early era，The large turbogenerator has arrived150megawatt。Alternating current motor[1] It was created by SerbiAn-American scientist Nicola·Tesla invented it。
