Main application of the working principle of jet vacuum pump

- Dec 16, 2018-

Principle: A device that uses a fluid to transfer energy and mass to obtain a vacuum, using a pressure-bearing water stream to be ejected through a nozzle that is symmetrically distributed to a certain degree of slope, and is concentrated at a focus. Since the jet water flow rate is particularly high, the pressure energy is converted into the velocity energy, and the suction zone pressure is lowered to generate a vacuum. A number of high-speed water flows away the gas to be pumped, and are fully mixed and compressed by the contraction section of the venturi and the throat, and the molecular diffusion energy exchange is performed, and the speed is balanced. The pressure is increased at the speed of the expansion section, and the atmospheric pressure is injected from the outlet into the water storage tank (pool), and the non-condensable gas is precipitated. The water is recycled through a centrifugal pump to complete the gettering process.

1. Advanced performance, energy saving, capital saving, corrosion resistance, widely used in chemical, pharmaceutical, textile, paper, grain and oil processing industries such as vacuum filtration, vacuum crystallization, vacuum transportation, vacuum distillation and other processes. It is an ideal product to replace the water ring, mechanical and slide valve vacuum pumps.
