Description

Technical Field

[0001] The utility model relates to the technical field of compressor components, and more specifically, to a compressor sliding vane and a rotary compressor. Background Art

[0002] Rotary compressors are widely used in various medium and small-sized compressed air devices and small air-conditioning refrigeration devices. They are also widely used in fields such as petrochemical, chemical, meteorological, construction, and aviation. For example, in the petrochemical industry, they are used for compressing medium and low-pressure gases in processes such as oil refining and gasification; in the chemical field, they are used for compressing medium and low-pressure gases in processes such as gas recovery and mixed gas generation.

[0003] The main components of a sliding vane compressor include a cylinder, a rotor, and sliding vanes. The rotor is eccentrically arranged in the cylinder, and several longitudinal grooves are formed on the rotor. Sliding vanes that can slide freely in the radial direction are installed in the grooves. The sliding vane compressor also has high reliability and durability and can operate normally under harsh environmental conditions.

[0004] As a key component in a rotary compressor, a compressor sliding vane is a thin sheet-like part used to separate and compress gases in a sliding vane compressor. They are usually installed in the longitudinal grooves of the rotor and can slide freely in the radial direction.

[0005] As the rotary compressor operates, the rotation of the rotor drives the crankshaft in the pump body to rotate. The rotation of the crankshaft enables the piston to rotate eccentrically and rotate to a certain extent around its own axis, and then under the influence of the spring, it pushes the sliding vane to perform repeated horizontal movements. However, during the repeated horizontal movements of the sliding vane, the upper and lower ends of the traditional sliding vane inevitably have sliding friction with the upper cylinder head, lower cylinder head, and cylinder, and the resulting sliding friction will cause a certain degree of energy loss in the system.

[0011] Further, the longitudinal height of the root of the clamping end is adapted to the inner diameter of the sliding vane spring.

[0012] Further, the angle of the spring groove is greater than or equal to 90 degrees.

[0013] Further, the side edges of the upper cut-off corner and the lower cut-off corner are arcs concave towards the inside of the sliding vane body or straight lines arranged obliquely.
