Jet pumps are devices that utilize the conversion of energy as a fluid flows to achieve delivery. It can be used for conveying liquid and gas, in chemical production, steam and water are often used as working fluid of jet pump, and it is used for vacuumizing so as to produce negative pressure in equipment. The existing jet pump mainly comprises a nozzle, a condenser and an expansion pipe, and the working process is that working fluid is ejected from the nozzle at high speed under high pressure, low pressure is generated in a mixing chamber, and the transported fluid is sucked into the mixing chamber and mixed with the working fluid to enter the expansion pipe. The pressure of the fluid gradually rises again as it passes through the expansion pipe and then is discharged outside. Depending on the working fluid used, it is generally classified into a steam jet pump and a water jet pump. The pump has no mechanical movement part, is not limited by conditions such as friction, sliding, vibration and the like, has simple structure, convenient use, strong environmental adaptability and reliable work, and is widely applied to various fields such as metallurgy, chemical industry, medicine, petroleum, food and the like.
