Rotor compressor

The rotor compressor is driven by the engine or the motor (mostly driven by the motor), and the other rotor (also known as the female rotor or the concave rotor) is driven by the oil film formed by the main rotor through oil injection, or by the main roto器2䀀

The air conditioner power is 4500w, and the 4A power cord 32A is open, why is it always tripped

The air conditioner power is 4500W, 4 square power cord, and the 32A air switch will trip for a period of time, because it can run for a period of time, so it is not a problem of excessive starting current, so let's analyze the power is 4500W Air conditio器2䀀

Analysis of common problems of air compressor oil filter

1.The perforation problem at the bottom of the oil filter The bottom of the oil filter is perforated, except for a few because the steel plate has blisters, but more because of the material problem of the shell steel. Whether the bottom is easy to perforate is related to the thickness of the shell, but it is not the main reason. When the material of the steel is not good

Excessive head resistance will cause compressor to trip

Excessive head resistance will cause compressor to trip The existence of compressor failure does not seem to have much to do with the brand. In other words, whether it is a Hitachi compressor, a Copeland compressor, or another brand of compressor, as long as it is used for a long time, there will be some problems of failure. . Compressor tripping is a common fault. When this failure usually occurs, we should comprehensively look for the cause of the failure.
