详情描述

A liquid-gas jet vacuum pump is a device that uses water as the vacuum medium. Water at a certain pressure is ejected through a Laval nozzle at supersonic speed, converting pressure energy into kinetic energy. At the nozzle exit, a low-pressure area is formed due to the entrainment effect of the high-speed gas flow. The water and the suctioned gas mixture are mixed in the mixing chamber, where energy exchange occurs. The mixed gas flow is decelerated and pressurized within the diffuser tube.


The Pump House Jet Energy Saver is primarily used in energy-saving renovations of urban pump houses. The equipment structure consists of an intake chamber, nozzle, mixing chamber, and diffuser chamber. It generates a certain negative pressure through the pressure and flow rate of municipal water, thereby drawing water from the reservoir for replenishment and circulation. The municipal water pressure is typically 0.3-0.4 Mpa, and the equipment is usually made of stainless steel, installed vertically.
