FAQs about refrigeration compressors, do you know these?

Why control the impurity content and moisture content of the compressor and air conditioning system? Impurities entering the friction surface of the moving parts in the compressor pump body will cause abnormal scratches and wear. Impurities entering the solenoid valve, expansion valve, control valve, capillary tube and stop valve in the refrigerator system will block the valve hole or make the valve close tightly. And fail.

Reasons for poor cooling of air conditioners

The temperature in summer is high, and many of the owners' friends need air conditioning to spend the hot summer in the room. However, some owners often have such problems when using air conditioning in summer, such as poor air conditioning cooling. So, what are the reasons for poor air conditioning and cooling? How to solve the poor air conditioning and cooling? One of the reasons for poor air-conditioning and cooling: Freon is not enough (commonly known as fluoride deficiency) <img src="{{media url=&quot;magefan_blog/Reasons_for_poor_cooling_of_air_conditioners.jpg&quot;}}" alt="" />

The key detection items of servo motor and common problems in servo motor detection

1).Servo motor detection -- cogging torque: Cogging torque is an inherent phenomenon of permanent magnet motor, which can make the motor torque fluctuate and produce vibration and noise. We measure the change of motor torque in a rotation cycle on a special test bench and analyze the distribution of cogging torque.
