Embodiment Construction
[0016] figure 2 It is an example of the present invention. The source fluid enters the water tank 10 through a pipeline, and is injected into the pressure storage tank 1 after being pressurized by the booster pump 8. The water level of the pressure storage tank 1 forms an interlock with the booster pump. When the water level of the pressure tank 1 is lower than the set value, the booster pump 8 starts. When the water level of the pressure storage tank 1 is higher than the set value, the booster pump 8 stops running. The check valve 9 can prevent the liquid in the pressure storage tank 1 from flowing backward to the booster. Pressure pump 8.
[0017] The pressure storage tank 1 is connected to the compressed air pump 3 through a gas pipe. Under normal temperature and pressure, the product VP of the gas volume and pressure in the pressure storage tank 1 is approximately a constant c. When VP is lower than the constant c, the compressed air pump 3 Start, inject gas into the pre...
