① It is used in vacuum distillation, concentration, dehydration, decolorization, drying, crystallization, filtration, degassing, material transportation, tail gas and dust absorption etc.
② When it is applied to spray condensing secondary steam, a large amount of secondary steam will be produced in some processes, which needs to be condensed. At the same time, a small amount of non condensable gas also needs to be discharged to maintain normal production. This kind of water jet pump is called water jet condenser, which is mainly composed of condensation and exhaust.
③ In the aspect of vapor-liquid mass transfer and absorption, the liquid flowing out at high speed meets the gas being ejected, and the process of air entrained by the jet is also the process of vapor-liquid two-phase mixing. Because the water jet pump has a large contact surface between the gas and liquid phases, and the high-speed jet has a large speed, which greatly strengthens the speed of the mass exchange process in absorption and mass transfer, and accelerates the chemical reaction or mass transfer process. Therefore, water jet pump has the function of both reactor and pump. It is used as absorption and mass transfer equipment in many occasions
④ In many large chemical plants and chemical fertilizer plants, the steam or hot water with certain energy is often discharged, resulting in energy waste. Water jet pump is used to inject low-energy fluid with less jars of high-energy fluid, so as to increase the energy site of the fluid, and then used in the production process.
⑤ The high-energy fluid used in the fluid power transmission and water jet pump is used to inject the low-energy fluid participating in the reaction, so as to replace the power equipment for fluid transmission.
