Compressed air drying and purification system composition

Since compressed air inevitably contains impurities such as solids, liquids, and gases, and each has its own characteristics, it cannot be achieved with a single device. Therefore, compressed air drying and purification becomes a system, a complete compressed air The drying purification system includes: 1) gas-liquid separator; 2) filter; 3) drying equipment and other facilities.

For an air conditioner with a heating power of 1390W+1050W, what is the power consumption for 1 hour of heating

Time flies, the air conditioner has just been out of service for two months, and it’s time to start using it again. With air-conditioning, our biggest concern is power consumption. After all, everyone is not rich.

What is servo drive?

As one of the importanttechnologies of CNC machine tools, industrial robots and other industrial machinery control, servo drive technology is widely concerned at home and abroad. In the last decade of the 20th century, the development of microprocessor (especially DSP), power electronics, network technology and control technology havelaid a good foundation for the further development of servo drive technology.

How to use refrigerant to empty the air conditioner after installation

Air, moisture and impurities contained in the air will cause pressure increase, current increase, noise increase, and power consumption increase in the air conditioner system, which will reduce the cooling (heat) capacity, and may also cause ice blockage and dirty blockage.

Refrigeration common fault terms and operation precautions

Frozen blocking: also known as "ice blocking". The phenomenon in which liquid freezing substances [such as ice] hinder the flow of refrigerant in the Freon refrigeration system. Often occurs in throttling mechanisms.

Danfoss medium temperature refrigeration compressor M series

liquid 1. Liquid back: When the refrigerant returned to the compressor is not a pure gas state, but contains liquid, the influence of the liquid refrigerant on the compressor is negative. If there is too much liquid, it may even cause liquid shock, even if there is no liquid shock, it will happen. Wet compression causes oil to run away.
