Working principle of air compressor

An air compressor (air compressor) is a device used to compress gas. The structure of air compressor and water pump is similar. Most air compressors are reciprocating piston type, rotating blades or rotating screws. Centrifugal compressors are very large applications.

AC servo driver wiring precautions

For signal line and encoder input line, please use shielded wire. Wiring length: the length of signal line from NC to AC servo driver is less than 3m, and the length of input line from AC driver to encoder is less than 20m. The ground wire should be thick wire as far as possible. According to the third grounding standard (grounding resistance < 100 Ω), one point grounding method should be adopted to connect the ground wire. If the motor and the machine tool are insulated, the motor should be grounded.

How to judge the presence of air in the air conditioner

In the refrigeration system, the non-condensable gases are mainly nitrogen, oxygen, hydrogen and water vapor in the air; because these working fluids do not condense with the refrigerant, they generally gather in the condenser or the liquid reservoir.
