Problems solved by technology

This type of compressor or vacuum pump is sealed by a contact line between the blades and the cylinder body, so the sealing performance is poor, the output pressure is low, and there is a lot of friction between the blades, the rotor and the cylinder body during rotation, resulting in the compressor Or the overall wear of the vacuum pump is fast, the life is short, and the efficiency is low

Abstract

The invention discloses a blade-typed compressor or vacuum pump which comprises a shell, a rotor, two same blades, four same sealing strips and two same cushion blocks, wherein, the rotor is positioned in the center, the shell is positioned in the exterior, the blades are positioned at two sides of the rotor, arranged in a hollow circular ring of the opposite angle of the shell to form an angle with the rotor, and tangent with the side of the cone of the rotor, the sealing strips are positioned between the rotor and the blades, one side of the plane of the sealing strip is jointed with the rotor, while one side of the cylindrical surface thereof is jointed with the blades, and the cushion blocks are positioned in the hollow circular ring of the opposite angle of the shell to just fill the opening formed by the blades, the rotor and the sealing strips. The invention has the advantages that: 1) all the sealing points are surface sealing, 2) the output volume is large, the pressure and efficiency are high, 3) the specific power is high, 4) the structure is compact and the processing is comparatively easy, and 5) the production cost is comparatively low.

Description

technical field [0001] The invention relates to a compressor or a vacuum pump, in particular to a vane compressor or a vacuum pump. Background technique [0002] The structure of the existing vane compressor or vacuum pump is that the rotor is eccentrically placed in the cylinder body, and the blades are placed in the rotor radially or at a certain angle to the rotor radius. When working, the rotor rotates at a high speed, and the blades are thrown out under the action of centrifugal force. It forms a sealed cavity with the cylinder block, and the volume changes when it rotates to generate pressure. The number of leaves is two or more. This type of compressor or vacuum pump is sealed by a contact line between the blades and the cylinder body, so the sealing performance is poor, the output pressure is low, and there is a lot of friction between the blades, the rotor and the cylinder body during rotation, causing the compressor Or the overall wear of the vacuum pump is fast,...
