The role of condensing pressure regulating valve

Condensing pressure regulating valve 　　 When the refrigeration device is running, if the condensing pressure is high, the compressor discharge temperature will rise; the compression ratio will increase; the cooling capacity will decrease; The higher the condensing pressure, the greater the above adverse effects. The high condensation pressure is mainly seen in summer. <img src="{{media url=&quot;The_role_of_condensing_pressure_regulating_valve.jpg&quot;}}" alt="" />

What is an air compressor

The machine used to generate compressed air is also called compressed air machine, also called air compressor, or air compressor for short. The motor directly drives the compressor to make the crankshaft produce rotational movement, drive the connecting rod to make the piston produce reciprocating motion, and cause the cylinder volume Variety.

Compressor protection measures against liquid strikes

Compressor protection measures against liquid strikes When too much liquid enters the cylinder and it is too late to discharge it from the exhaust valve, a liquid blow will occur in the cylinder. The high pressure generated during the liquid blow damages the cylinder, piston, connecting rod, etc., so it is necessary to take a Series of protective measures.
