The Improvement of Refrigerators Rotary Oil Pump

Abstract:

Screw refrigerators are widely used in subzero refrigeration and storage fields. The manufacturers always use rotor-type pumps as their lubricating oil pumps. This paper introduces the advantages of screw refrigerators, the usage of oil pumps and the working environments. It mainly studies the common faults of oil pump, proposes several design ideas for analysis and comparison and determines the final improvement schemes on the premise of comprehensively considering structure, performance and cost.
