Abstract

The invention discloses a rotary compressor and a heat pump system thereof. The rotary compressor includes: a housing, a cylinder, a crankshaft, a piston and a sliding vane, the cylinder is arranged in the housing, and a cylinder cavity and a sliding vane groove are arranged in the cylinder. A crankshaft passes through the cylinder bore, and the crankshaft has an eccentric portion within the cylinder bore. The piston is a hollow structure, and the piston is sheathed on the eccentric part. The sliding piece is reciprocally slidably arranged in the sliding piece groove, and the tip of the sliding piece is in contact with the outer peripheral wall of the piston. According to the rotary compressor of the embodiment of the present invention, the weight of the piston can be greatly reduced, and the cost of the piston can be reduced. The useless power consumption generated by high-speed operation improves the performance of the compressor.

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...
