When the liquid pump 1 is started, the liquid in the first gas compression cylinder 2 can be firstly conveyed into the second gas compression cylinder 3, meanwhile, the liquid is worked to enable the liquid to have higher pressure, the gas in the second gas compression cylinder 3 is compressed into the gas storage tank 4 through the liquid through the one-way valve 11, and at the moment, the one-way valve 9 is closed. At the same time, as the liquid in the first gas compression cylinder 2 flows out, its upper gas pressure decreases, the check valve 10 closes, and the gas to be compressed flows into the first gas compression cylinder 2 through the compressed air inlet 12 via the check valve 8. When the gas in the second gas compression cylinder 3 is completely sent out, the liquid pump 1 is shut down.
When the liquid pump 1 is started again, the liquid conveying direction is changed, the liquid is conveyed from the second gas compression cylinder 3 to the first gas compression cylinder 2, meanwhile, work is applied to the liquid, the liquid is made to have higher pressure, and the gas in the first gas compression cylinder 2 is compressed into the gas storage tank 4 through the one-way valve 10 through the liquid. The non-return valve 8 is closed at this time. At the same time, as the liquid in the second gas compression cylinder 3 flows out, its upper gas pressure decreases, causing the check valve 11 to close and the gas to be compressed to flow into the second gas compression cylinder 3 through the check valve 9 via the compressed air inlet 12. When the gas in the first gas compression cylinder 2 is completely sent out, the liquid pump 1 is turned off.
The above process is repeated continuously, the gas is compressed into the gas storage tank 4 continuously, and when the gas pressure meets the use requirement, the compressed gas is sent out through the gas output pipeline 13 and the valve 15. When more impurities are accumulated in the air storage tank 4, the pollution discharge control valve 15 can be opened, so that the impurities are discharged through the pollution discharge pipeline 14 and the pollution discharge control valve 18.
