12、 Steam jet pump

After steam enters the nozzle, it sprays out at high speed, generating low pressure. The gas is sucked in and mixed in the mixing chamber. After passing through the enlarged tube, kinetic energy is converted into pressure energy. If the inhaled gas comes from a container and the container is depressurized, it can be called a jet vacuum pump.

Performance characteristics:

(1) This pump has no mechanical moving parts and is not limited by friction, lubrication, vibration and other conditions, so it can be made into a pump with high pumping capacity. As long as the structural material of the pump is selected appropriately, it is extremely advantageous for eliminating gases with corrosive properties, gases containing mechanical impurities, and water vapor. (2) Simple structure, light weight, and small footprint. (3) The working steam pressure is 4-9 × 105Pa, which is a common water vapor source in metallurgy, chemical, pharmaceutical and other enterprises. Due to the aforementioned characteristics, steam jet pumps are widely used in industrial sectors such as metallurgy, chemical engineering, pharmaceuticals, petroleum, and food.

The impeller is designed as an axial flow type. The speed is very high, and if the motor power, impeller diameter, and pipeline diameter are large enough, the flow rate can be very high.
