Abstract

The invention provides a pump body assembly and a compressor with the same. The pump body assembly comprises a roller and a sliding sheet, wherein first magnetic substances are arranged on the roller;a second magnetic substance is arranged on the sliding sheet; and when the roller is subjected to the operations of air sucking and exhausting, the first magnetic substances cooperate with the secondmagnetic substance to produce magnetic force, so that the head of the sliding sheet is always in contact with the peripheral surface of the roller. According to the pump body assembly disclosed by the invention, the first magnetic substances and the second magnetic substances which can interact are arranged on the sliding sheet and the roller at the same time, and through the magnetic force produced between the first magnetic substances and the second magnetic substances, the sliding sheet is always in contact with the roller, so that the situation that in the operating process of the pump body assembly, the sliding sheet is separated from the surface of the roller is avoided, the problem that the pump body assembly is subjected to liquid hammer is solved, and the reliability of the pumpbody assembly is effectively improved.

Description

technical field [0001] The invention relates to the technical field of compressor equipment, in particular to a pump body assembly and a compressor having the same. Background technique [0002] When the rotary compressor operates at light load and low frequency, due to the small load during cooling or heating, it is easy to cause incomplete evaporation of the evaporator. The refrigerant coming out of the evaporator is in a gas-liquid two-phase state. When the gas-liquid mixed refrigerant enters It is easy to cause liquid shock in the compressor cylinder, and the liquid shock is very harmful to the compressor: first, it increases the power of the compressor, which is easy to cause wear and tear, which is very unfavorable to the reliability of the compressor; second, it may cause the rollers to separate from the sliding vanes , causing the sliding plate and the roller to collide to form abnormal noise and affect the reliability. At the same time, the separation of the roller ...
