What are the consequences of the trend of piston refrigeration compressors

The refrigerating medium sucks liquid or wet vapor into the refrigeration compressor due to its failure or insufficient heat absorption, which is called a tidal car. There are also many reasons for the tidal vehicles: whether the elevation of the gas-liquid separator in the system is lower than the standard (required above 1.2m); the automatic control liquid level in the system fails; the manual liquid supply is too large or too rapid (or in the throttle valve) Leaking or opening too much); Open the suction shut-off valve too fast; because of the excessive liquid storage in the auxiliary equipment, the heat load is small, and the load is too fast; sudden increase of the heat load (quick freezing) or failure to adjust in time after frosting will cause refrigeration Compressor tide car.

　　 Piston refrigeration compressor trendy cars will cause the following consequences. The editor of okmarts.com will show you:

　　 (1) The refrigerant enters the compressor, causing the lubricating oil to generate a large number of bubbles, destroying the oil film on the lubricating surface, and making the oil pressure unstable.

　　 (2) Make the moving parts run without good lubrication, resulting in picking; in severe cases, the axle holding and the main shaft Waba alloy melt.

　　(3) The refrigerant enters the compressor, causing the cylinder liner to rapidly cool and shrink, and hug the piston; in severe cases, the cylinder liner, piston, connecting rod, and piston pin are damaged.

(4) Because the liquid is incompressible, the force on the connecting rod and piston in the tide car is far beyond the design value, which is very easy to cause damage; because the liquid is incompressible, in the tide car, the exhaust valve group and the dummy cover It will be lifted by the impact of the liquid; in severe cases, it will cause the safety spring to deform, or even smash the body, cylinder head, and penetrate the gasket to injure the human body.
