7.5kw Two Stage Water Ring Vacuum Pump

2SK Pump description:

2SK sequence two-phase drinking water ring vacuum pump and 2SK- Pone series two-phase drinking water ring vacuum pump—air injection pump device are vacuum pumps and vacuum device with higher degree of vacuum, large evacuation pace in substantial vacuum intervals, compact development, reliable application, and effortless assembly and disassembly which developed according with stipulations of Styles and Standard Parameter of JB/TQ354-84(Drinking water Ring Vacuum Pump and Water Ring Air CZPT).

This device consists of one-stage air injection pump and two-stage h2o ring vacuum pump which can be utilized independently if shopper required.

This two-stage water ring vacuum pump or unit is relevant for pumping air and other non-corrosive gas which is insoluble in h2o and without that contains strong particles so as to acquire large vacuum in sealed vessel.

Doing work Basic principle:

The doing work theory of two-stage h2o ring vacuum pump is illustrated in the subsequent Determine. When the eccentrically-assembled impellers(5) in the pump entire body (3) rotate, h2o is thrown off outwards due to the centrifugal drive .This will kind a rotating h2o ring(six) in between the within floor of pump entire body and the impeller. Then the inside of surface of drinking water ring will make contact with impeller hub. When the impeller hub rotates clockwise, the inside surface area of the h2o ring breaks absent gradually from the hub in the course of the 1st half change and the cavity among two adjacent impellers expand gradually as a result the pumped gasoline is drawn into the cavity by means of crescent suction hole(seven) by means of pump inlet air pipe(four) for the duration of the CZPT half switch, the inside floor of water ring approaches the impeller hub progressively and the cavity between two adjacent impellers shrink progressively with the gas compressed and the force of which preserve decreasing and air got expelled. When the inner strain override the strain of the external pressure, the gas within the vessel is evacuated steadily ,so it will obtain vacuum.


Air injection pump is a kind of jet injector, the functioning theory of which is as follows: specified degree of vacuum inside the evacuated container is shaped because of to the operation of the two-phase h2o ring vacuum pump and the atmosphere pump is interconnected when it reaches max vacuum, at this time, the air (or pressurized gases) is drawn into the pipe rapidly because of to the fantastic pressure variation between the air (or pressurized gases) and the ingestion pipe. After the spout of the air, the flow fee is accelerated, so the strain minimizes, in this way it will acquire large vacuum diploma of the spout(remarkably greater than the vacuum degree of pump),then it carries on to draw gas into the pump.


The structural drawings of two-phase water ring vacuum pump with capacity more than 1.5m3/min is illustrated in the figure two, the for a longer time impeller(seventeen) and the shorter impeller(sixteen) are fixed to the shaft(2) with pins, and between the two impellers, it is fixed by shaft sleeve(20) and locked with spherical nut so it types rotor. The two impellers eccentrically put in inside of the pump physique and supported by two single row radial ball bearings. The rotor is connected to motor shaft with coupling(eighteen) and rotates jointly with the motor. CZPT impeller(seventeen),longer pump human body(nine) and the suction portion types substantial vacuum degree shorter pump body(5),shorter impeller(sixteen)and the discharge portion forms reduced vacuum degree. The air outlet of substantial diploma vacuum section and the suction inlet of minimal degree vacuum segment are linked into dual-phase tandem with speaking pipe. The two segments are separated by intermediate wall (A)(7)and intermediate wall(B)(6) and the intermediate wall(B) has intake port. The 2SK sequence two-stage pumps are mechanically sealed at equally ends.

There is a drinking water inlet hole in the higher diploma vacuum segment by means of which the make-up drinking water is crammed into the lengthier pump entire body, whilst the make-up water for low diploma vacuum segment is discharged from the large degree vacuum. (The make-up drinking water for the reduced degree vacuum of 2SK-12A,2SK-20A and 2SK-30A are also partly provided from the drinking water supply pipe but it require to be regulated by means of valves.) The high and lower degree vacuum segments are secured jointly with draw-in bolt. The air injection pump is composed of inlet air pipe, jet nozzle, air valve body and diffuser.
