Air compressor classification, working principle and air compressor selection

Air compressor classification, working principle and air compressor selection The air compressor is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy, and is a pressure generating device for compressed air.

Common failure phenomena of air-conditioning compressor

If your home's air conditioner is not cooling, it is likely that the compressor has malfunctioned. Why do you say this? Since the compressor is different from non-moving parts such as condensers and evaporators, it needs to run at high speed during system器2䀀

The main difference between brushless DC motor and DC servo motor

Different definitions: (1) Brushless DC motor is a typical mechatronics product, which is composed of motor body and driver. Brushless motor refers to the motor without brush and commutator (or collector ring), also known as commutator less motor. As early as the 19th century, when the motor was born, the practical motor was the brushless form, that is, the AC squirrel cage asynchronous motor, which has been widely used. However, the asynchronous motor has many insurmountable defects, so that the development of motor technology is slow. The transistor was born in the middle of last century, so the brushless DC motor using transistor commutation circuit instead of brush and commutator came into being. This new type of brushless motor is called electronic commutation DC motor, which overcomes the defects of the first generation of brushless motor.

Factors affecting heat transfer on the refrigerant side

1.Flow direction and velocity of steam In the condenser, when the refrigerant vapor contacts the low-temperature wall surface, it exotherms and condenses into a liquid film, and flows downward under the action of gravity.
