Technical Field

The invention relates to the technical field of compressors, in particular to a compressor pump body assembly, a compressor and an air conditioning system comprising the compressor pump body assembly.

Background

In recent years, rolling rotor compressors have become popular worldwide due to their features of simple structure, low cost, high reliability, and the like, and are particularly widely applied in the fields of air conditioners, water heaters, refrigeration equipment, and the like.

The tail of the sliding sheet of the rolling rotor compressor is certain under the action of gas force in the stable operation process under a certain working condition, and the head of the sliding sheet is influenced by the change of gas force in a compression cavity of the cylinder and the centrifugal force of the roller, so that the sliding sheet can break away from the roller, the head of the sliding sheet collides with the roller and the tail of the sliding sheet to collide with the cylinder, serious collision rattling is generated, and the noise of the compressor is obviously worsened. Meanwhile, the sliding sheet of the compressor is separated from the roller, so that the compression cavity of the air cylinder is communicated with the air suction cavity to generate air leakage, the compression capacity of the compressor is reduced, and the energy efficiency is reduced.

In order to solve the problems, the roller and the slide of part of the compressor are hinged to prevent the slide from being separated from the roller, but the hinge structure is complex in processing, low in precision and high in cost. Meanwhile, the thickness of the roller thickness hinge groove is reduced, the rigidity is reduced, the end face sealing performance is poor, and the thin-wall roller cannot be processed into the hinge groove. In addition, the roller cannot rotate during the operation of the compressor, so that the friction between the roller and the eccentric circle of the crankshaft is increased.

In some compressors, a magnetic material is provided on the roller, and the end of the vane is attracted to the outer circumferential surface of the roller by magnetic force to prevent the roller from being separated from the vane. The design makes the whole roller processing complicated, and increases along with compressor operating frequency, and when centrifugal force is greater than magnetic force, the gleitbretter still breaks away from the roller, because of roller arc surface and cylinder inner wall contact, and interfere the gleitbretter and lead to leaking greatly in the compressor, the noise is poor, and if the roller magnetic force position is not in the gleitbretter groove direction after shutting down, then lead to the compressor to start and can't establish and inhale, the exhaust pressure differential.

Although the two methods are both used for solving the problem that the sliding sheet is separated from the roller and collides with the roller, the two methods have certain defects and do not well solve the existing technical problems.
