Abstract

The invention discloses a cam type multistage compression miniature high-pressure air pump. The pump comprises a cylinder body, a rear end cover, a motor support, a motor, a cam and a compression plunger, wherein the motor comprises a motor stator and an electric motor rotor, the two ends of the motor stator are kept constantly with the cylinder body through the motor support, the motor rotor is arranged on the outer side of the motor stator in a sleeved mode, the cam is arranged on the outer side of the motor rotor in a sleeved mode and is fixed with the motor rotor, a compression cavity is arranged on one side, right faces to the cam, of the cylinder body, and the compression plunger is installed in the compression cavity; and the rear end cover is fixed with the cylinder body, the compression cavity is sealed through the rear end cover, the cam is in one-to-one correspondence with the compression plunger, the cam is driven to rotate through rotation of the motor rotor, and the compression plunger is driven by the cam to do reciprocating motion in the compression cavity. According to the pump, the cam type multistage compression miniature high-pressure air pump can realize multi-stage compression of gas, the multistage compression plunger is integrated in the cylinder body, so that the integration level of the structure is improved; and the pump has the advantages of being compact in structure and small in volume weight.

Description

technical field [0001] The invention relates to a cam-type multi-stage compression miniature high-pressure air pump, which belongs to the technical field of pneumatic components in the mechanical industry, in particular to a high-pressure air pump capable of realizing the miniaturization and integration of the multi-stage compression high-pressure air pump. Background technique [0002] The multi-stage compression high-pressure air pump is a machine used to increase gas pressure and transport gas, and belongs to a working machine that converts the power energy of the prime mover into gas pressure energy. It has many types and wide uses, and is known as "general machinery". Air pumps are widely used in many sectors of the national economy and national defense construction, especially in petroleum, chemical, power and other industrial fields, and have become indispensable key equipment. Some synthesis processes can be carried out under high pressure, and the gas is pressurize...
