Steam jet ejectors operate by passing a pressurized working steam through a Laval nozzle, reducing pressure and increasing speed to supersonic levels. This mixture of steam and the medium being evacuated moves forward at high speed, entering an expansion tube where it slows down and increases pressure, and is then discharged to the next stage jet or atmosphere, creating a vacuum in the suction chamber. Depending on the user's requirements for vacuum level, each steam jet vacuum pump can be equipped with a single stage or multiple stages of ejectors in series. The more stages, the higher the vacuum level (lower residual pressure). Generally, the relationship between suction pressure and the number of stages is as follows:
The intermediate condensers are available in three types: spray direct cooling, mixed direct cooling, and between-tube direct cooling.

YGJQ Series Steam Jet Ejectors Technical Parameters
1. The working steam pressure for the permit is 0.3MPa (absolute pressure). Please specify this at the time of ordering so we can customize the nozzle based on your actual working steam pressure.
2. The illustrated condenser is a mixed direct cooling type; we can customize a shell-and-tube condenser according to the customer's requirements.
3. This喷射器can operate normally without a muffler. However, the addition of a muffler can reduce operating noise.
