Principles and structure of hydraulic ejector

Principle and application:
Hydraulic ejector is a kind of mechanical device with three kinds of effective energy, such as vacuum pumping, condensation, drainage and so on. It is the use of a certain pressure of the water through the symmetry are distributed into a certain side slope of the spray. Polymerization in a focal point, because the jet speed is higher, they form a negative pressure around the room so have a vacuum device, also because the two steam jet flow with the direct contact heat exchange, most of the steam condenses into water, a small amount of uncondensed steam and non condensable gas due to friction with each other at high speed the spray water flow, mixing and extrusion, the diffuser is excluded, the formation of higher vacuum for indoor. Hydraulic ejector is widely used, mainly used in vacuum and evaporation system, vacuum pump, vacuum evaporation, vacuum filtration, vacuum crystallization, drying and deodorizing process, is sugar, pharmaceutical, chemical, food, salt, monosodium glutamate, milk, fermentation and some light industry, the defense department needs a wide range of equipment. Structure such as multi nozzle and steam ring (guiding plate). As well as with the multi-stage pump water, low installation, improve the performance of its work, so it has a certain advanced nature, is a vacuum condensation equipment innovation, welcomed by the user units around the welcome.
Principles and structure of hydraulic ejector
Structural advantage:
Hydraulic ejector is composed of a device body, cover, nozzle, nozzle base plate, guide plate, a diffuser and a one-way valve and other parts, stainless steel nozzle, injection nozzle seat board is processed by high quality steel, the other parts are cast iron, the nozzle structure with multi nozzle, so that get the larger water vapor contact area, is conducive to heat exchange, to obtain better effect of vacuum. Machining precision, high precision, so that the jet flow accurately gathered in the same focus. The guide plate is used to slow down the steam (or air) flow rate, the vapor chamber is evenly into the jet to avoid deviation, reduce the shot efficiency. The device has the advantages of compact structure precision, high strength, used for vacuum evaporation system, due to the pumping effect of combined in one device and greatly simplifies the process of condensation condenser and vacuum pump, vacuum pump and device for condenser of old than the original, can be saved to the vacuum pump, condenser and water separator equipment.
And there are the following advantages:
(1) the hydraulic jet is small in size, light in weight and compact in structure. And the efficiency is relatively high, power consumption is lower than the vacuum system, the province of investment.
(2) the operation is simple and easy to maintain, so it is not necessary to manage the full time personnel, so the noise is low and no need to consume the lubricating oil because it has no mechanical drive part.
(3) can be installed outside the floor, covers an area of less, you can save the construction area of the plant and installation costs.
