Novel compressor

Abstract

The embodiment of the invention provides a novel compressor. The novel compressor comprises a cylinder body and a piston assembly arranged in the cylinder body. The piston assembly comprises a first piston, a second piston arranged in the first piston and a movable assembly connected with the first piston, wherein the movable assembly is used for driving the first piston and the second piston to move back and forth. The cylinder body is provided with a first compression chamber for limiting a space for the first piston to move up and down, and when the first piston moves back and forth in the first compression chamber, gas outside the cylinder body is sucked and compressed to generate first compressed gas; the cylinder body is provided with a gas storage chamber for storing gas compressed for the first time, and the gas storage chamber is connected with the first compression chamber; the cylinder body is further provided with a second compression cavity for limiting the vertical moving space of the second piston, the second compression cavity is connected with the air storage chamber, and when the second piston moves back and forth in the second compression cavity, the first-time compressed air is sucked in from the air storage chamber and compressed to generate second compressed air. The compressor is small in size, high in compression efficiency and low in failure rate.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a novel compressor. Background technique [0002] A compressor is a driven fluid machine that lifts low-pressure gas into high-pressure gas. It inhales low-temperature and low-pressure gas from the outside, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure gas to the exhaust pipe. [0003] Traditional compressors are divided into single-cylinder compressors and multi-cylinder compressors. During operation, the motor directly drives the compressor to make the crankshaft rotate, drive the connecting rod to make the piston reciprocate, and cause the cylinder volume to change. [0004] Among them, the single-cylinder compressor has low compression efficiency and poor compression capacity, and high-pressure gas cannot be obtained by a single compression. The motor and piston generate a lot of heat during use and a...

AI Technical Summary

Problems solved by technology

[0004] Among them, the single-cylinder compressor has low compression efficiency and poor compression capacity, and high-pressure gas cannot be obtained by single compression. The motor and piston generate a lot of heat during use and are easily damaged, which reduces the service life of the compressor.

However, the multi-cylinder compressor has a large volume, complex structure, high production cost, and a high failure rate of multiple pistons during asynchronous compression, making maintenance difficult, which further reduces the compression efficiency.
