W Hydraulic ejector

Product Overview

W series hydraulic ejector is a mechanical device with three effective functions of vacuum pumping, condensation and drainage. It uses a certain pressure of water flow to spray out through a nozzle symmetrically and evenly distributed with a certain inclination, and converge on a focus. Due to the high speed of the jet water flow, a negative pressure is formed around the chamber to create a vacuum. In addition, because the secondary steam is directly contacted with the jet water flow for heat exchange, most of the steam is condensed into water. A small amount of unconsolidated steam and unquestioned gas are also removed through the diffuser due to friction, mixing and extrusion with the high-speed jet water flow, Make the chamber form a higher vacuum. Hydraulic ejectors are widely used, but at present, the manufacturer of hydraulic ejectors is small and the variety is not complete. For this reason, our company has improved the design in recent years by using multiple nozzles, steam rings (guide plates) and other structures, as well as multi-stage pumps to feed water. The installation height is only 4.5 meters, which improves and improves its working performance and has certain advancement, It is an innovation of vacuum condensation equipment and is welcomed by users all over the world.

Product features

The hydraulic injector is composed of the body, cover, nozzle, nozzle seat plate, guide plate, diffuser, one-way valve and other components. The nozzle is made of stainless steel, the nozzle seat plate is processed by high-quality steel, and the other parts are cast iron. The nozzle adopts the structure of multiple nozzles, so as to obtain larger water steam contact, which is conducive to the heat exchange and better vacuum effect. The nozzle seat plate is precisely machined and has high precision, so that the jet water can accurately focus on the same focus. The guide plate is used to slow down the flow rate of steam (or air), so that the steam can be evenly introduced into the chamber to avoid deflection of jet water flow and reduce the pumping efficiency. The whole device is compact, precise and high strength. It is used in the vacuum evaporation system. Because the condensation of the condenser and the suction of the vacuum pump can be combined in one equipment, the process flow is greatly simplified. Compared with the original vacuum pump plus the old condenser, vacuum pump, condenser, water separator and other equipment can be saved, Besides, it also has the following advantages: (1) The hydraulic ejector is small in size, light in weight and compact in structure. The efficiency is relatively high, the power consumption is lower than that of the vacuum pump system, and the investment is saved. (2) Simple operation and convenient maintenance, no need for full-time personnel to manage, because there is no mechanical transmission parts, so the noise is low, no need to consume lubricating oil. (3) It can be installed in low position outdoors, occupying a small area, which can save the building area and installation cost of the plant.

Product use

It is mainly used in vacuum and evaporation systems to carry out vacuum pumping, vacuum evaporation, vacuum filtration, vacuum crystallization, drying, deodorization and other processes. It is an equipment widely required by sugar, pharmaceutical, chemical, food, salt, monosodium glutamate, milk, fermentation and some light industry and national defense sectors.
