Flow distribution mechanism suitable for multi-stage air compressor

Abstract

The invention discloses a flow distribution mechanism suitable for a multi-stage air compressor. The flow distribution mechanism is provided with a first-stage air inlet, a first-stage exhaust hole, a second-stage air inlet, a second-stage exhaust hole, a third-stage air inlet, a third-stage exhaust hole, a fourth-stage air inlet and a fourth-stage exhaust hole. The first-stage air inlet, the first-stage exhaust hole, the second-stage air inlet, the third-stage air inlet, the fourth-stage air inlet and the fourth-stage exhaust hole each contain an air valve. The eight air valves are used for achieving corresponding one-way flow of gas. The flow distribution mechanism is further provided with a first communication hole, a second communication hole and a third communication hole. The first communication hole communicates with the first-stage exhaust hole and the second-stage air inlet. The second communication hole communicates with the second-stage exhaust hole and the third-stage air inlet. The third communication hole communicates with the third-stage exhaust hole and the fourth-stage air inlet.

Description

technical field [0001] The invention belongs to the technical field related to component aerodynamics, and more specifically relates to a flow distribution mechanism suitable for multi-stage air compressors. Background technique [0002] A high-pressure air compressor is a machine used to increase gas pressure and transport gas. It belongs to a working machine that converts the power energy of the prime mover into gas pressure energy. There are many types of high-pressure air compressors, and they are widely used, so they are known as "general machinery". Air compressors are widely used in many sectors of the national economy and national defense construction, especially in petroleum, chemical, power and other industrial fields. They are mainly used in chemical production processes. These synthesis processes can be carried out under high pressure, and the gas is pressurized to the required pressure by a compressor. In addition, refrigeration and gas separation are also ins...

Problems solved by technology

At present, the multi-stage compression cylinders of multi-stage compressors are distributed in a star shape, and most of the distribution mechanisms are independent distribution valve blocks, which have complex structures and large volumes, and are not conducive to miniaturization and integration.
