An air compressor oil-gas separation tank

Abstract

The invention discloses an air compressor oil and gas separation tank. The air compressor oil and gas separation tank comprises a tank body which is provided with an oil and gas input port, an oil liquid input port and a compressed air output port; a separation barrel is arranged in the tank body and comprises a barrel body with the upper end provided with a V-shaped opening; the portion, located on the opening side of the V-shaped opening, of the barrel body is provided with a first blocking edge matched with the inner wall of the tank body; the other side of the barrel body is provided with a second blocking edge matched with the inner wall of the tank body; the outer wall of the barrel body, the first blocking edge, the second blocking edge and the inner wall of the tank body form an oil and gas separation cavity in a surrounding and covering manner, and the oil and gas separation cavity is formed in the periphery of the barrel body in an encircling manner; and the side, located on the second blocking edge, of the barrel body is provided with a flow guiding through hole for communicating the oil and gas separation cavity with the interior of the barrel body. By means of the oil and gas separation tank, oil and gas are effectively separated, the oil content of compressed air output to an oil and gas filter from the oil and gas separation tank is reduced so that the service life of the oil and gas filter can be prolonged, and the using cost is reduced.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to an oil-gas separation tank of an air compressor. Background technique [0002] The compressed air required for vehicle braking, door opening and closing, suspension pedal lifting and other pneumatic devices in the car is provided by the on-board air compressor system. The traditional on-board air compressor is a reciprocating piston air compressor with a complex structure. It takes up a lot of space and is not suitable for new energy vehicles. For example, a screw air compressor for electric passenger cars disclosed in patent 200820169730.4 includes a screw air compressor main unit, a motor connected to the air compressor main unit, an air storage tank, an oil storage tank and an oil cooler, wherein the air storage tank and the oil storage tank It is integrated with the main engine of the air compressor to solve the problem that the existing vehicle air compressor takes ...

AI Technical Summary

Problems solved by technology

However, the existing vehicle-mounted air compressors, especially the screw air compressors used for new energy electric vehicles, are mainly due to the incomplete separation of oil and gas in the oil-gas separation tank at the front end of the oil-gas filter, resulting in the output compression of the oil-gas separation tank after oil-gas separation. The oil content in the air is high, which in turn makes the filter load of the oil and gas filter heavier, resulting in a greatly shortened service life of the oil and gas filter, which requires frequent replacement and increases the cost of use
