Abstract

The invention discloses a novel crankshaft of a refrigeration compressor. The novel crankshaft of the refrigeration compressor comprises a crankshaft long shaft body (namely, a long shaft body), a crankshaft short shaft body (namely, an eccentric part short shaft body), a balance block, a near end spiral groove, a centrifugal groove, a far end spiral groove, an exhaust hole, a centrifugal hole, an oil inlet hole, an oil hole, a crankshaft oil sleeve and other structures. The novel crankshaft of the refrigeration compressor is simple in structure, easy to machine and install, feasible in low-speed oil pumping and reasonable in high-speed oil pumping. The problems that a traditional inverter compressor is insufficient in pumped oil at the lower speed and surplus in pumped oil at the high speed are solved.

Description

technical field [0001] The invention relates to the technical field of refrigeration compressor equipment, in particular to a crankshaft of a novel refrigeration compressor. Background technique [0002] As we all know, any refrigeration equipment needs to use a refrigeration compressor, so in-depth research on refrigeration compressors is particularly important. In recent years, as "environmental protection, energy saving and emission reduction" has gradually become the theme of the development of the times, the research on energy saving of refrigeration compressors has become more and more in-depth, and has been highly valued by consumers and manufacturers. [0003] Generally speaking, refrigeration compressors can be classified into variable frequency compressors and fixed frequency compressors according to their control principles. Among them, the market share of variable frequency compressors is increasing day by day due to their energy-saving features. At the same tim...
