Micro oil-free double-cylinder compressor

Abstract

The invention discloses a micro oil-free double-cylinder compressor which comprises a machine body. The machine body is formed by sequentially connecting a first chamber, a power chamber and a secondchamber; air inlet pipes are connected to one sides, far away from the power chamber, of the first chamber and the second chamber; a first air cylinder is fixedly connected to the upper end of the first chamber; a second air cylinder is fixedly connected to the upper end of the second chamber; exhaust valves are arranged on the top part of the first air cylinder and the second air cylinder and areconnected with an exhaust pipe through a drainage pipe; the drainage pipe is a T-shaped silicone pipe; pistons are arranged on the bottom part of the first air cylinder and the second air cylinder; and air inlet valves are arranged on the pistons. The micro oil-free double-cylinder compressor provided by the invention has the beneficial effects that the effective working volume of the product isincreased through a double-cylinder structure, so that the air output is increased; and meanwhile, air is directly introduced into the first chamber and the second chamber so as to cool a connecting rod, so that heat is dissipated quickly; the air cylinders are arranged outside the machine body, so that the structure can be supported, and meanwhile, the surfaces of the air cylinders can be effectively cooled; and the air inlet valves are arranged on the pistons, so that the product volume is reduced.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to a miniature oil-free double-cylinder compressor. Background technique [0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. [0003] The twin-cylinder compressors currently on the market have the following deficiencies: [0004] 1. The volume of the compressor is large, but the effective working volume is low, so that the air output of the compressor is small; [0005] 2. The heat dissipation performance of the compressor is poor, the durability is low, and the service life is short; [0006] 3. Som...
