1. The screw refrigeration compressor shaft seals usually include movable ring, retaining ring and O-ring.
2. The shaft seal for refrigeration compressor has two models, Model 1 and Model 2.
3. In the refrigeration compressor, the refrigerant is prevented from infiltrating into the system to the outside or the air, and a shaft seal must be provided between the extended end of the crankshaft and the body. Friction ring type shaft seals are widely used in open compressor series. The structure comprises a spring, a spring seat, a sealing ring, a fixing ring and a movable ring.
