An ejector is a typical two-phase fluid device for water and gas. The momentum required for the gas phase movement comes entirely from the water jet, with the gas moving under the "enveloping" action of water droplets, achieving high efficiency in the intake chamber through cross-sectional area and flow rate. This equipment fundamentally differs from the structure of past water and steam jet pump groups. It employs a spiral nozzle to break the traditional design of vertical and crossed water and gas flow, making the air particles around the water jet uniformly distributed and further increasing their contact area. This enhances mixing capabilities and creates a co-directional flow, benefiting the expulsion of the gas entrained by the water jet, significantly improving suction efficiency. It also prevents the water jet from tilting and causing vibrations, advantages not available in rotary vacuum pumps and older ejectors.
Water Jet Vacuum Pump is used for extracting condenser vacuum and other vacuum equipment in thermal power plants, belongs to energy-saving and environmentally friendly type.
Application Range: Retrofitting of old water extraction systems for N3MW to N600MW units, conversion from steam extraction to water extraction, or for use with new units.

Section 2: Features of Water Jet Vacuum Pumps:
1. Simple structure, safe & reliable, long lifespan, low noise, and minimal investment.
2. Low water quality requirements; flow components are made of corrosion-resistant materials and specially designed for high efficiency.
3. Excellent starting performance, low energy consumption, and fast vacuum establishment.
4. Achieves the utilization of excess speed, suctioning and heating non-condensable gases within the shaft seal heater.
