specific Embodiment approach

[0026] Specific implementation methods: such as figure 1 As shown, a multi-cylinder gas compressor includes a cylinder body 8, wherein an intermediate frame body 9 is arranged in the middle of the inner cavity of the cylinder body (the intermediate frame body can be a frame body structure surrounded by four sides or also can be a closed box structure), the middle frame 9 is slidably fitted in the inner cavity of the cylinder body 8 and isolates two two-stage compression chambers 6 from both ends of the inner cavity of the cylinder along the sliding direction, and the middle frame The inner cavity forms an air intake chamber, and an equal-width cam 1 is arranged in the inner cavity of the middle frame. The rotation direction of the equal-width cam 1 is consistent with the sliding direction of the middle frame. Two inner sidewalls are used to contact both sides when the equal width cam rotates and form an equal width cam mechanism, and the rotating shaft of the equal width cam i...

Abstract

The invention discloses a multi-cylinder type gas compressor. The multi-cylinder type gas compressor comprises a cylinder and is characterized in that a middle frame is arranged at the middle position of an inner cavity of the cylinder in a sliding fit manner and divides the inner cavity of the cylinder into two second-level compression cavities along the two ends in the sliding direction; an equal-width cam is arranged in an inner cavity of the middle frame, and an equal-width cam mechanism is formed; each of the two second-level compression cavities is provided with a second-level cavity air outlet cavity for compression air outflow; each of the two inner side walls of the middle frame is provided with a second-level cavity air inlet valve for air inflow; each of two matched outer side walls, used for being in sliding fit with the inner cavity of the cylinder, of the middle frame is provided with a first-level cavity air inlet for air inflow, and each of the middle portions of the inner walls, used for being in sliding fit with the two matched outer side walls, of the cylinder is provided with a cylinder air inlet. The multi-cylinder type gas compressor has the beneficial effects that the structure is simple, few motion components are arranged, cost is low, work vibration is weak, and the gas compression efficiency is high.

Description

technical field [0001] The invention relates to the field of gas compressors, in particular to a multi-cylinder gas compressor. Background technique [0002] A gas compressor is a power device that converts mechanical energy into gas pressure energy. It is often used to provide gas power for pneumatic tools. It is also commonly used for pressure delivery of oxygen, hydrogen, ammonia, natural gas, coke, etc. Furnace gas, inert gas and other media. In addition, the engine cylinder is also a gas compressor. [0003] Existing gas compressors generally adopt a piston-type structure, that is, the output shaft of the motor drives the piston to perform reciprocating linear motion through components such as the crankshaft, connecting rod, piston pin, and piston head to achieve gas compression. [0004] This existing gas compressor has defects such as many moving parts, high cost, large vibration, one round trip of the piston can only realize one compression of the cylinder chamber,...
