Radial multi-cylinder synchronous revolving compressor

Abstract

The invention belongs to the technical field of displacement compressor, and relates to a radial multi-cylinder synchronization rotary compressor. The radial multi-cylinder synchronization rotary compressor comprises a crank shaft driven by a motor, a cylinder and a cylinder cover of a cylinder body, a bearing supporting the crank shaft, a stander and a piston making reciprocating movement in the cylinder body, and is characterized in that at least one set of bidirectional piston and a cylinder corresponding to the bidirectional piston are arranged on the crankshaft driven by the motor and on the same plane vertical to the crankshaft, wherein the bidirectional pistons are distributed circumferentially and are provided with a rotating center respectively. The crank shaft, the cylinder body and the pistons can rotate synchronously along the rotating centers respectively. An intake, an exhaust port, an intake and an exhaust valve are arranged on the cylinder cover or the piston bodies. The radial multi-cylinder synchronization rotary compressor has the advantages of small size, good heat radiating effect, low noise, good air-tightness, high working efficiency and therefore is suitable for spreading application on the same type of compressor.

Description

technical field [0001] The invention belongs to the technical field of displacement compressors, in particular to a radial multi-cylinder synchronous rotary compressor. Background technique [0002] At present, although there are many types of general reciprocating piston air compressors, the structure is similar, that is, the motor outputs power through the crankshaft, and the connecting rod drives the piston to reciprocate in the cylinder to compress the gas and do work to produce compressed air. Many defects: one is that the cylinder and the frame of the compressor are positioned with each other, that is, they do not move. The compressor of this structure is not conducive to the heat dissipation of the compressor cylinder; the other is that the motor of a compressor only passes through the crank connecting rod mechanism. Drive one or two pistons to work, the power is small and the efficiency is low; the third is that the compression stroke is long, the power consumption i...

Problems solved by technology

[0002] At present, although there are many types of general reciprocating piston air compressors, the structure is similar, that is, the motor outputs power through the crankshaft, and the connecting rod drives the piston to reciprocate in the cylinder to compress the gas and do work to produce compressed air. Many defects: one is that the cylinder and the frame of the compressor are positioned with each other, that is, they do not move. The compressor of this structure is not conducive to the heat dissipation of the compressor cylinder; the other is that the motor of a compressor only passes through the crank connecting rod mechanism. Drive one or two pistons to work, the power is small and the efficiency is low; the third is that the compression stroke is long, the power consumption is large, the cylinder is subjected to large lateral force, and the eccentric mass is large, resulting in large amplitude of vibration or resonance, and the noise of the compressor Large, short service life; Fourth, due to the large lateral force on the crankshaft and piston, the piston ring is easy to wear, resulting in poor sealing performance
