Abstract

The invention provides a piston type air compressor. The piston type air compressor comprises a main shaft, a drive component, an eccentric wheel and a plurality of piston assemblies. The main shaft is driven by the drive component to rotate around the axis. The main shaft is sleeved with the eccentric wheel, and the axis of the eccentric wheel is parallel to the axis of the main shaft. The multiple piston assemblies are arranged around the circumferential direction of the main shaft. Each piston assembly comprises a cylinder, a piston and a connecting rod, wherein the two ends of the cylinderare provided with an air inlet and an air outlet correspondingly, the piston is arranged in the cylinder, one end of the connecting rod is connected with the piston, the other end of the connecting rod is connected with the eccentric wheel, and when the eccentric wheel rotates, the connecting rod drives the piston to reciprocate in the cylinder. According to the piston type air compressor, through the arrangement of the multiple pistons, the multiple cylinders alternately generate compressed gas, the effective air inflow and air outflow area of the piston type air compressor is increased, constant air supply is ensured, the air supply pressure is stable, and the performance is greatly improved.

Description

technical field [0001] The invention relates to a piston air compressor. Background technique [0002] At present, the air compressors used in fuel cell systems on the market are mainly centrifugal and screw. However, the efficiency of centrifugal or screw air compressors is relatively low, it is difficult to increase the air flow rate, and there is a risk of oil leakage due to the use of oil lubrication. [0003] Existing air compressors used in other fields are usually single-piston. However, the efficiency of the traditional single-piston air compressor is too low to meet the needs of the fuel cell system. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a piston air compressor in order to overcome the defects of low efficiency of the single piston air compressor in the prior art and unable to meet the requirements of the fuel cell system. [0005] The present invention solves the above technical problems th...
