SPB water jet pump
SPB water jet pump
Advantage characteristics:
A baffle is arranged above the nozzle, and the installation position is high, the length is large, and the flow conductivity is good.
working principle:
The water jet pump has a certain pressure of working medium water, which is sprayed to the suction chamber at a high speed through a nozzle, and the pressure energy of the water is changed into kinetic energy to form a high-speed jet; the gas in the suction chamber is forcibly carried and mixed with the high-speed jet to form a gas-liquid. The mixed flow enters the diffuser, thereby reducing the pressure in the suction chamber and forming a vacuum. In the expansion section of the diffuser, the kinetic energy of the mixed jet is converted into pressure energy, the speed is lowered, the pressure is increased, and the gas is further compressed, together with the water. Outside the pump, the gas and water are separated in the water tank, the gas is released into the atmosphere, and the water is recycled by the water pump, and the vacuum is continuously recovered. The nozzle of the single-stage water jet pump may be a single nozzle structure composed of one tapered nozzle, or a multi-nozzle structure in which a plurality of orifices are formed in one orifice plate.
