Maintenance of screw air compressor

1. Maintenance of intake air filter element. The air filter is a component that filters out air dust and dirt. The filtered clean air enters the compression chamber of the screw rotor for compression. Because the internal clearance of the screw machine only allows particles within 15u to filter out.

Why does the scroll refrigeration compressor reverse? What about reversal?

We know that the operation of the internal compression structure of the refrigeration compressor has a fixed direction. First of all, we need to make it clear: the occurrence of reverse rotation must be unfavorable for the refrigeration compressor.

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.
