Vane type revolving compressor

Abstract

The invention relates to a rotary vane compressor, which comprises a rotor 1, a cylinder 2, a vane 3 and an end cover, wherein the rotor 1 offsets in the cylinder 2; the outside surface of the rotor 1 is in tangency and contact fit with the inner hole surface of the cylinder 2; the rotor 1 is provided with an arc groove 8; and the vane 3 is in fastened and sealed connection with the cylinder 2 and two lateral ends. The rotary vane compressor is characterized in that the compressor is provided with a first slide block 4a and a second slide block 4b which are arranged in the arc groove 8 and are in rotary fit with the arc groove 8; because two independent slide blocks are adopted to replace an integral rotary column, the matching surface among the first slide block 4a, and the second slide block 4b and the vane 3 can be processed and treated conveniently, including grinding and various surface treatments, so as to obtain high precision dimension, shape, position, surface coarseness, planeness, surface rigidity and the like. Therefore, the fit among the first slide block 4a, the second slide block 4b and the vane 3 is smoother, and friction loss and leakage loss are reduced, so as to be favorable for the reduction of shaft work consumption of the compressor.

Description

technical field [0001] The present invention relates to a compressor, in particular to a vane type rotary compressor, more specifically to a vane type rotary compressor including a rotary column structure. Background technique [0002] The vane compressor has the advantages of small size, light weight, simple structure and good dynamic balance performance, so it is widely used in the fields of air compression, refrigeration and air conditioning. However, the vane of the traditional vane compressor has relative motion relative to the cylinder and the end cover, so there must be a certain movement gap between them, which brings hidden dangers such as leakage loss and friction loss. In order to overcome the above-mentioned disadvantages of the traditional vane compressor, a rotary compressor that fastens and seals the vane, the cylinder and the end cover together has appeared, which includes the cylinder, the rotor, the vane, the end cover and the rotating column; The cylinder...
