The life of air compressor bearings and the causes of damage

If the air compressor loses one bearing or does not pay attention to the correct use of the bearing, the air compressor will not be able to operate normally, and it will greatly shorten the service life of the bearing, which will bring us unnecessary losses.

Performance characteristics of Panasonic Minas series Panasonic AC servo

The output power of Panasonic AC servo motor is generally 0.1-100 W, and the power frequency is divided into 50 Hz, 400 Hz, etc. It is widely used in various automatic control and recording systems 1.Miniaturization design 1) Through the best thermal analysis of the driver, the miniaturization is realized. Compared with the past, the volume is 75% and the weight is 80% 2) The new punching process of thin die steel plate has greatly reduced the iron loss, shortened the motor length (70% in the past) and reduced the number of drive models. It adopts current grading method to prepare and maintain. One driver is suitable for multiple motors and can identify automatically.

What is the reason why the freezer is not cooling

It may be that the capillary is blocked and the refrigerant flow does not enter the evaporator. It may also be that the refrigerant needs to be replenished or the refrigeration system is leaking. If the buffer tube inside the compressor ruptures, there may be loose screws or it will cause no cooling. It is also possible that the expansion valve and the discharge valve are not adjusted properly, causing cold air to leak out. Need to check one by one, and then take the medicine.

Troubleshooting of low valve temperature of screw chiller

The outlet temperature of the expansion valve of the screw chiller reflects the evaporation temperature, which is a factor that affects the heat exchange. Generally, the difference between it and the outlet temperature of the refrigerant water is 5~6℃.
