Problems solved by technology

However, under certain low-frequency operating conditions, the suction pressure and discharge pressure of the compressor are small, and the difference between the discharge pressure and suction pressure is small. The rollers cannot keep track, and the performance is that the compressor makes a "da da da" abnormal sound
[0004] Therefore, how to solve the problem that the sliding plate and the roller are easily separated in the prior art has become an important technical problem to be solved by those skilled in the art

Abstract

The invention discloses a compressor and a matching structure of a roller and a sliding plate of the compressor. According to the matching structure of the roller and the sliding plate, the outer circumferential face of the roller is provided with annular protrusions or annular grooves extending in the circumferential direction; and the end, making contact with the roller, of the sliding plate is provided with grooves matched with the annular protrusions, or protrusions matched with the annular grooves. In this way, the matching structure of the roller and the sliding plate of the compressor, the problem that in the prior art, a sliding plate and a roller are separated can be avoided.

Description

technical field [0001] The invention relates to the technical field of compressors, more specifically, to a compressor and a matching structure of rollers and sliding vanes thereof. Background technique [0002] The rotary compressor includes components such as crankshaft, roller, cylinder and sliding vane. The roller is installed on the eccentric part of the crankshaft and rotates concentrically with the eccentric part of the crankshaft. The inner wall of the cylinder is provided with a sliding vane installation groove, and the sliding vane is installed on the and the sliding piece installation groove is provided with an elastic member to ensure that the sliding piece can be elastically expanded and contracted in the sliding piece installation groove. The sliding plate can slide freely and is always in contact with the roller under the action of elastic force, thereby separating the closed cavity formed by the cylinder and the roller into an air suction chamber and an exhau...
