Antifriction device of compressor

Abstract

The invention relates to a compressor anti-friction device, which consists of first and second bearing pads installed on the upper and lower sides of the cylinder to jointly form an inner space, a discharge valve is formed on each bearing pad, and a discharge valve is formed on the cylinder to form a connection with the first space, The suction port and discharge port connected to the second space, the partition plate connected to the rotating shaft to divide the interior of the cylinder into the first space and the second space, and a plurality of vanes that are in contact with the partition plate and can move linearly in the cylinder. It is characterized in that a rotating component groove is provided at the blade contact end corresponding to the partition plate, and the rotating component groove of the blade is inserted into the rotating component. The compressor of the present invention reduces the frictional loss and wear between the partition plate and the blades during operation, improves the working efficiency of the compressor, and works safely and reliably for a long time. The product has simple structure, easy installation and low cost.

Description

technical field [0001] The invention relates to an anti-friction device in the field of compressors, in particular to a compressor anti-friction device which can reduce the friction between the partition plate and blades of a compound leaf rotary compressor. Background technique [0002] Compressors generally convert mechanical energy into compressed fluid compression energy. Compressors can be divided into piston compressors, screw compressors, centrifugal compressors (also called turbo compressors) and compound blade rotary compressors. [0003] Among them, the compound leaf rotary compressor is equipped with movable blades and contacts with the rotating body, and divides the interior of the cylinder into a suction area and a compression area. When the rotating body rotates, the suction area and the compression area are continuously exchanged according to the phase difference of the rotating body, and the suction fluid is compressed and discharged.

Problems solved by technology

[0012] However, the linearly moving blades 6A, 6B of the conventional compound leaf rotary compressor contact both side surfaces of the rotating partition plate 5, and friction occurs between the contact surfaces of the blades 6A, 6B and the partition plate 5. Reduce the working efficiency of the compressor, especially the wear of the friction surface during long-term use, resulting in the leakage of compressed gas and reducing the reliability of the compressor

[0013] This shows that above-mentioned existing compound leaf rotary compressor still has many defectives, and Cheng needs to be improved
