Structure of a hydrojet

The hydraulic ejector is composed of a body, cover, nozzle, nozzle seat plate, guide plate, diffuser pipe and check valve, and the nozzle adopts the structure form of multiple nozzles in order to obtain a larger contact area of water vapor, which is conducive to the progress of heat exchange and obtains a better vacuum effect. The nozzle seat plate is machined with precision and high precision to deflect the jet flow and reduce the pumping efficiency. The whole device has compact and precise structure, high strength, used in vacuum evaporation system, because the condensation effect of the condenser and the pumping effect of the vacuum pump can be combined in one equipment at the same time, greatly simplifying the process flow, compared with the original vacuum pump and the old condenser device, can save vacuum pump, condenser, water distributor and other equipment.
