Common faults and solutions of refrigeration compressors

Liquid shock refers to the situation where the refrigerant fails to absorb heat or evaporates sufficiently, and the refrigerant liquid or wet steam is sucked into the compressor by the compressor. It is called liquid shock.

Analysis of the circuit diagram of the two compressors' phase failure protection

Analysis of the circuit diagram of the two compressors' phase failure <br><br> Air compressor phase failure <br><br> circuit In the figure, KP is the electrical contact pressure gauge Ai is the CD4073 AND gate circuit, Az is the ~D4025 NOR gate circuit, and A3 is the CD4071 OR gate circuit. The 7806 three-terminal fixed integrated voltage regulator is used as the control circuit for the DC working power supply. When the AC power fails, the relay KA is released and the motor stops.

What do the refrigeration system overcooling and overheating mean

The so-called "supercooling" is to pass the condensed saturated liquid through a certain device (such as a subcooler) and method (or measure) to recool it so that its temperature is lower than the saturation temperature under the condensation pressure, which is called supercooling .

Why can't the lubricating oil in the air compressor be replaced by hydraulic oil

Lubricating oil 　　Lubricant is a kind of lubricant. It is located between two objects in relative motion and has the function of reducing friction between two objects due to contact. In addition, it also has the functions of cooling,
