Principle of water jet vacuum pump operation: the vacuum obtaining device using fluid to transfer energy and mass adopts a certain pressure water flow to be sprayed out by means of nozzles which are symmetrically and uniformly distributed into a certain side slope, and the water flow is converged on a focus. Because the flow velocity of the sprayed water is extremely high, the pressure energy is converted into the velocity energy, so that the pressure in the air suction area is reduced to generate vacuum. Several high-speed water flows grab the sucked gas, and the gas is fully mixed and compressed with the throat diameter through the contraction section of the venturi tube to perform molecular diffusion energy exchange, so that the speed is balanced. The speed is reduced and the pressure is increased in the expansion section, the expansion section is sprayed into the water tank from the outlet and is higher than the atmospheric pressure, the non-condensable gas is separated out, and the water is recycled by the centrifugal pump to finish the air suction process. The vacuum degree generated by the unit is high and the time is short.
