The principle structure, advantages and disadvantages of scroll refrigeration compressor

Principle: The scroll line pattern of the moving plate and the static plate are the same, but the phase difference is 180°C; they mesh to form a series of closed spaces; the static plate does not move, and the moving plate revolves around the center of the fixed plate with the eccentricity as the radius. When the moving disc revolves, it meshes in sequence, so that the crescent-shaped area is continuously compressed and reduced, so that the gas is continuously compressed and finally discharged from the center hole of the static disc

Basic theoretical knowledge points of air compressor air

1. What is the definition of the standard state of air? Answer: The definition of the standard state is: when the air suction pressure is 0.1MPa and the temperature is 15.6℃ (the domestic industry defines it as 0℃), the air state is called the standard state of air.

Precautions for the use of screw air compressor oil

Precautions for the use of screw air compressor oil Precautions for the use of screw air compressor oil: It is forbidden to mix air compressor oils of different brands and grades. The old oil must be drained when replacing. It is strictly forbidden to add or filter and reuse. Because although the color of the compressor oil does not change on the surface, the consumption of additives may have exceeded the limit.
