Bidirectional liquid booster pump capable of being used for chip cleaning

The utility model relates to the technical field of chip cleaning booster pumps, in particular to a bidirectional liquid booster pump capable of being used for chip cleaning. According to the technical scheme, the high-pressure air cylinder comprises an air cylinder body and a high-pressure cylinder body, cylinder covers are installed at the two ends of the air cylinder body, driving pipe openings are formed in the cylinder covers, and the high-pressure cylinder body and the air cylinder body are fixedly connected through an extension isolation sleeve; a piston rod is fixedly connected to the piston plate, and the end of the piston rod penetrates through the extension isolation sleeve and is fixed to the high-pressure piston through threads. According to the chip cleaning device, the booster pump is used for pressurizing cleaning liquid, so that the purpose of cleaning a chip is achieved, the rear end of the high-pressure piston is of an isolation structure according to chip cleaning characteristics, gas-liqu
