The arrangement of the pump body of the vacuum pump determines the overall structure of the pump.

​A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physical-chemical methods to extract air from the pumped container to obtain a vacuum.

The air pump uses the cylinder after removing the spark plug as the air source, and uses the spark plug housing as the intake duct of the air pump.

A typical application example is to use a micro air pump to maintain the vacuum or positive pressure in the container.

Wide range of use: the working medium can be hydraulic oil, water and most chemically corrosive liquids, with high reliability and long maintenance-free life.

Pneumatic booster pump is divided into gas-liquid booster pump and gas booster pump. The principle of the gas-liquid booster pump is to use the low air pressure of the large area piston to generate...

Because the hub motor has the characteristics of independent driving of a single wheel, it can be implemented relatively easily whether it is front-wheel drive, rear-wheel drive or four-wheel drive.

A ring permanent magnet is fixed inside the DC motor. The current generates ampere force through the coil on the rotor. When the coil on the rotor is parallel to the magnetic field, the direction o...

​The excitation method refers to the way in which the magnetic field is generated in the rotating electrical machine.

A DC generator is a machine that converts mechanical energy into DC electrical energy. It is mainly used as DC motor for DC motor, electrolysis, electroplating, electric smelting, charging and exci...

​The structure of the DC motor should be composed of two parts: the stator and the rotor. The stationary part of the DC motor is called the stator.

One is the armature reverse connection method, that is, keep the polarity of the terminal voltage of the excitation winding unchanged, and reverse the motor by changing the polarity of the terminal...
