Abstract

The invention provides a rotary compressor and a heat pump system with the rotary compressor. The rotary compressor comprises a shell, a cylinder, a crank shaft, a piston and a sliding sheet. The cylinder is arranged in the shell, and a cylinder cavity and a sliding sheet groove are formed in the cylinder. The crank shaft passes through the cylinder cavity, and is provided with an eccentric portion which is located in the cylinder cavity. The piston is of a hollow structure, and sleeves the eccentric portion. The sliding sheet is arranged in the sliding sheet groove in a reciprocating sliding mode, and the front end of the sliding sheet makes contact with the peripheral wall of the piston. By the adoption of the rotary compressor, the weight of the piston can be greatly reduced, the piston cost is reduced, the balance weight of a main counterbalance of the compressor can be reduced by half, the eccentric mass of the compressor is reduced to improve the reliability of the compressor, the useless power consumption generated by high-speed running of the piston is also reduced, and the performance of the compressor is improved.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a rotary compressor and a heat pump system with the same. Background technique [0002] The rolling piston in the compressor is located in the eccentric part of the crankshaft. The mass of the piston constitutes the main part of the eccentric mass. The weight of the piston affects the balance weight on the rotor and the centrifugal inertial force generated by the eccentric mass of the compressor that is not concentric with the axis, thus affecting compressor reliability. [0003] The function of the piston is to transmit power (inner circle), compress gas (outer circle), build a compression chamber (outer circle), seal the end face (upper and lower end faces), convert the sliding friction at the tip of the slide plate into rolling friction, and the piston itself revolves And the rotation produces useless power consumption, which is related to the weight of the piston. The piston of t...
