Abstract

The invention discloses a rotor assembly, a pump rotor assembly, an assembling method of the pump rotor assembly and a compressor. The rotor assembly sleeves a crankshaft and comprises a first balancing block (1), an oil baffle plate (2), rotor iron cores (3) and a second balancing block (4), wherein the first balancing block (1), the oil baffle plate (2), the rotor iron cores (3) and the second balancing block (4) are axially arranged along the crankshaft from top to bottom in a sequence. With the adoption of the rotor assembly, the problem that the balancing blocks in the prior art easily cause disturbance between the oil baffle plate and a rotor and a stable and continuous flowing field cannot be formed well can be solved.

Description

technical field [0001] The invention relates to the technical field of air compression, in particular to a rotor assembly, a pump body rotor assembly, an assembly method thereof, and a compressor. Background technique [0002] The oil discharge of the compressor has an important impact on its own reliability and the heat transfer efficiency of the refrigeration system. With the development of miniaturization and high speed of compressors, how to design an efficient, compact and easy-to-install oil retaining structure has become an important issue in compressor design. [0003] In order to reduce the oil circulation rate of the refrigeration compressor, a current solution is to arrange the oil baffle above the balance weight on the rotor. Such as figure 1 As shown, the compressor is composed of a casing, a liquid separator, a pump body assembly, a motor stator assembly, a motor compressor, and refrigeration oil; wherein, the rotor assembly is composed of a rotor core 3 and ...
