Maintenance and repair of refrigeration compressors

1.Pay attention to the oil surface of the oil mirror of the compressor, and ensure that the oil surface is within the range specified by the oil mirror. If the compressor lacks oil, it will cause chain failures such as seizure, shaft wrapping and burning 器2

Exhaust gas of refrigeration compressor is overheated. Are these reasons caused

Compressor: It is a complex machine running at high speed. Ensuring adequate lubrication of moving parts such as compressor crankshafts, bearings, connecting rods, pistons, etc. is the basic requirement for maintaining the normal operation of the machine. For this reason, compressor manufacturers require the use of specified grades of lubricating oil, and require regular inspection of the lubricating oil level and color

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
