Abstract

The invention discloses a gas compression pump with a special-shaped cavity. The pump comprises a stator and a rotor, wherein the stator is a cylinder with a special-shaped cylindrical surface inner cavity, an inlet and an outlet; the special-shaped cylindrical surface inner cavity is formed by combining two arc surfaces and two non-arc surfaces; the rotor consists of a rotor body and two pairs of combined sliding plates; the rotor body is a cylinder with a transmission shaft, a centering shaft and cross guide grooves; the two pairs of combined sliding plates are vertically arranged in the guide grooves; each cover plate is a flat plate with a bearing hole; the two end faces of the stator are matched with the cover plates to form a sealed cavity; the rotor is matched with the bearing holes in the cover plates through the transmission shaft and the centering shaft; an external driving couple makes the rotor rotate through the transmission shaft; and when the rotor rotates, the combined arc surfaces of the special-shaped cylindrical surface inner cavity are matched with the rotor, the two pairs of combined sliding plates are controlled to slide crosswise, gas is sucked into the inlet and pressed out of the outlet, and positive pressure is formed in an outlet area.

Description

technical field

[0001] The invention relates to a special-shaped cavity air pump, which belongs to the technical field of fluid machinery and compressors. Background technique

[0002] The compressed air pump is a mechanical device that produces compressed gas. It is widely used in chemical industry, petroleum, cement building materials, glass, textile, metallurgy, machinery, power electronics, vehicles, ships, mining and other fields.

[0003] Compressor pumps are divided into two types: volumetric and speed, according to their working principles. Positive displacement air pumps mainly include piston type, screw type, sliding vane type, and Roots type. Among them, the structure of the sliding vane air compressor is the simplest, and its comprehensive technical performance is relatively good. It is an important direction for the development of positive displacement air compressors. . The vane compressor is mainly composed of a stator and a rotor with multiple vanes, which ...
