Description

Pump body assembly, compressor and air conditioner

Technical Field

The invention relates to the technical field of household appliances, in particular to a pump body assembly, a compressor and an air conditioner.

Background

The rolling rotor type compressor divides a sealed crescent cavity formed by a cylinder, a roller, a crankshaft eccentric part and an upper flange and a lower flange into a high-pressure cavity and a low-pressure cavity through a matching structure of the roller and the sliding vane, the sliding vane reciprocates in a sliding vane groove, a spring is arranged in a sliding vane back tail groove structure, and the acting force of the spring on the sliding vane ensures that the sliding vane is tightly pressed on the outer circle surface of the roller, so that the sealing of the high-pressure cavity and the low-pressure cavity is realized. In the running process of the rolling rotor type compressor, the sliding vane is subjected to the comprehensive action of various acting forces such as gas force, friction force, inertia force, acting force of the sliding vane groove and the roller on the sliding vane, and the direction and the size of each acting force are changed along with the change of the rotation angle of the compressor, and the movement state of the sliding vane is changed along with the change of the direction and the size of each acting force.
