Compression mechanism and compressor with same

Abstract

The invention discloses a compressing mechanism and a compressor with the compressing mechanism. The compressing mechanism comprises an air cylinder, a piston, a sliding sheet, an upper flange and / or lower flange and a pressure channel. The air cylinder is provided with an air cylinder cavity, a sliding sheet groove, an air suction opening and an exhaust opening are formed in the air cylinder, the air suction opening and the exhaust opening are formed in the two sides of the sliding sheet groove, and the end, close to the outer wall of the air cylinder, of the sliding sheet groove is closed. The piston is arranged in the air cylinder cavity in an eccentric rotating manner. The sliding sheet is arranged in the sliding sheet groove in a reciprocating sliding manner. The front end of the sliding sheet abuts against the outer wall of the piston, and an elastic part abutting against the rear end wall of the sliding sheet groove is arranged at the rear end of the sliding sheet. The upper flange is arranged at the upper end of the air cylinder, and the lower flange is arranged at the lower end of the air cylinder. One end of the pressure channel communicates with the air position, on the exhaust opening side, of the air cylinder cavity, and the other end of the pressure channel communicates with the position, on the rear end side of the sliding sheet, of the sliding sheet groove. According to the compressing mechanism, the energy consumption of the compressor and abrasion to the sliding sheet can be reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compression mechanism and a compressor with the compression mechanism. Background technique [0002] The compression mechanism includes a cylinder, a piston, a slide plate and a slide plate spring. The cylinder has a cylinder chamber, and the cylinder is provided with a slide plate groove and suction ports and exhaust ports located on both sides of the slide plate groove. In the chamber, the sliding vane is reciprocally slidable in the sliding vane groove, and a vane spring is provided at the rear end of the vane so that the front end of the vane always stops against the outer wall of the piston. The cylinder chamber is jointly controlled by the piston and the vane. A suction chamber and a compression chamber are defined, and the front end of the sliding vane will be subjected to the pressure of the gas in the compression chamber.

AI Technical Summary

Problems solved by technology

However, during the working process of the compressor, the gas pressure in the compression cavity is different in the suction, compression and exhaust stages, that is, the gas pressure on the front end of the slide plate is different in the suction, compression and exhaust stages. The size is different. Before the compressor is exhausted, the pressure in the compression chamber is lower than the exhaust pressure. At this time, there is a pressure difference between the front and rear ends of the slide. The pressure on the rear end of the slide is greater than the pressure on the front end of the slide. At this time, the pressure generated by the sliding vane on the piston is relatively large, which increases the friction between the front end of the sliding vane and the piston, which not only increases the energy consumption of the compressor, but also causes serious wear on the front end of the sliding vane.
