Lubricating oil recovering and cooling device of vehicle-mounted air compressor

Abstract

The invention discloses a lubricating oil recovering and cooling device of a vehicle-mounted air compressor. The device is characterized by comprising an air compressor cylinder head; a breathing port is formed in the upper end of the air compressor cylinder head; a lengthened hose is mounted at the upper end of the breathing port; a heat dissipating air port is formed in the upper end aligned to the air compressor cylinder head, and is set as double air ports; and the double air ports are communicated through a heat dissipating pipe. The lengthened hose can stop dust from entering an air compressor body by the breathing port to cause unnecessary wear; the lengthened hose is fixed above the air compressor, and an outlet is upwards, so that a breathing purpose is achieved, lubricating oil discharged from the breathing port can be collected to flow back into the air compressor body, and enough lubricating oil is guaranteed to lubricate the air compressor; and the heat dissipating air port is set as the double air ports for cooling the air compressor cylinder head in a targeted manner, so that the heat dissipating effect is excellent, the overhigh temperature of the cylinder head is prevented, and the service life of the cylinder head is prolonged.

Description

technical field [0001] The invention belongs to the technical field of automobile air compressors, and in particular relates to a lubricating oil recovery and cooling device for a vehicle air compressor. Background technique [0002] The compressor is used on the road sweeper to provide the air source for the special dust removal device of the road sweeper. Since the air compressor itself is designed with a breathing port for relieving the pressure in the inner cavity of the air compressor, when the air compressor is running at high speed, it is inevitable that Discharge the mist lubricating oil. After a long time, the amount of lubricating oil will be too low, and the lubrication between the moving parts of the air compressor will be poor, resulting in excessive wear and even damage. Because the air compressor runs at high speed for a long time, high temperature will be generated at the cylinder head of the air compressor. Since the air compressor is located in a relatively...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problem of oil injection and overheating of the air compressor in the prior art, the purpose of the present invention is to provide a lubricating oil recovery and cooling device for the vehicle-mounted air compressor. The extended hose can prevent dust from entering the air compressor body through the breathing port , to prevent dust from entering the air compressor and causing unnecessary wear; it not only achieves the purpose of breathing, but also collects the lubricating oil exhaled from the breathing port and flows back into the air compressor body to ensure sufficient lubricating oil to lubricate the air compressor; double air outlets Targeted cooling of the cylinder head of the air compressor, the cooling effect is good
