Product Description
Steam jet pump (pressure matcher)
Structural characteristics
A vacuum obtaining device that uses fluid to transfer energy and mass. It uses water flow with a certain pressure, which is symmetrically distributed and sprayed out at a certain oblique angle through nozzles, converging at a focal point.
Because the jet water flow rate is particularly high, the pressure energy is converted into velocity energy, reducing the pressure in the suction area and generating a vacuum.
Several high-speed water flows will carry away the gas being sucked, and after fully mixing and compressing through the contraction section and throat diameter of the Venturi tube, molecular diffusion energy exchange and velocity equalization will occur.
After passing through the expansion section, the velocity decreases and the pressure increases, becoming greater than atmospheric pressure. It is then sprayed into the water storage tank (pool) from the outlet, and the non-condensable gas is separated. The water is recycled using a centrifugal pump to complete the suction process.

Typical cases
Nine Dragons Paper (Taicang) Co., Ltd. High temperature and high pressure steam pressure regulator post-reduction temperature regulator
The pressure matcher uses a single-nozzle structure, and the shell is made of 12Cr1MoV forging.
Power steam: P1=8.83MPa T1=540°C Q1=8T/H
Steam to be sucked: P2=0.8~0.91MPa T2=220~240°C Q2=5T/H
Desuperheating water parameters: Pb=12~15Mpa Tb=158°C Qb=2T/H
Outlet steam: P3=1.8Mpa T3=240°C Q3=15T/H
This project was put into operation in June 2012 and has been operating stably with good economic benefits.
