2sk-6A Double Stage Liquid Ring Vacuum Pump

2SK Pump description:

2SK series two-phase drinking water ring vacuum pump and 2SK- Pone series two-phase drinking water ring vacuum pump—air injection pump unit are vacuum pumps and vacuum unit with substantial degree of vacuum, higher evacuation pace in high vacuum intervals, compact construction, reliable application, and simple assembly and disassembly which created in accordance with stipulations of Styles and Standard Parameter of JB/TQ354-eighty four(H2o Ring Vacuum Pump and Water Ring Air CZPT).

This device consists of one particular-stage air injection pump and two-phase water ring vacuum pump which can be utilized separately if consumer necessary.

This two-stage h2o ring vacuum pump or unit is applicable for pumping air and other non-corrosive gas which is insoluble in drinking water and with no that contains solid particles so as to obtain high vacuum in sealed vessel.

Working Theory:

The working basic principle of two-stage h2o ring vacuum pump is illustrated in the adhering to Figure. When the eccentrically-assembled impellers(5) in the pump entire body (3) rotate, water is thrown off outwards due to the centrifugal drive .This will form a rotating h2o ring(six) in between the inside surface of pump human body and the impeller. Then the inside of surface of h2o ring will get in touch with impeller hub. When the impeller hub rotates clockwise, the inside surface of the h2o ring breaks away slowly from the hub in the course of the 1st half flip and the cavity among two adjacent impellers grow gradually hence the pumped gas is drawn into the cavity via crescent suction gap(seven) by means of pump inlet air pipe(4) during the CZPT 50 % switch, the within surface area of drinking water ring techniques the impeller hub steadily and the cavity amongst two adjacent impellers shrink gradually with the gasoline compressed and the force of which maintain lowering and air acquired expelled. When the interior strain override the stress of the exterior force, the fuel inside of the vessel is evacuated progressively ,so it will get vacuum.


Air injection pump is a variety of jet injector, the functioning theory of which is as follows: specified diploma of vacuum inside of the evacuated container is formed due to the procedure of the two-stage h2o ring vacuum pump and the ambiance pump is interconnected when it reaches max vacuum, at this time, the air (or pressurized gases) is drawn into the pipe speedily because of to the wonderful force big difference amongst the air (or pressurized gases) and the ingestion pipe. Following the spout of the air, the stream fee is accelerated, so the stress minimizes, in this way it will obtain high vacuum diploma of the spout(remarkably higher than the vacuum diploma of pump),then it continues to draw gas into the pump.


The structural drawings of two-stage water ring vacuum pump with capacity over one.5m3/min is illustrated in the determine two, the more time impeller(17) and the shorter impeller(sixteen) are fixed to the shaft(2) with pins, and amongst the two impellers, it is fixed by shaft sleeve(twenty) and locked with round nut so it varieties rotor. The two impellers eccentrically mounted inside the pump entire body and supported by two single row radial ball bearings. The rotor is related to motor shaft with coupling(eighteen) and rotates jointly with the motor. CZPT impeller(seventeen),longer pump physique(nine) and the suction element types high vacuum degree shorter pump human body(five),shorter impeller(sixteen)and the discharge part varieties minimal vacuum diploma. The air outlet of high degree vacuum phase and the suction inlet of low degree vacuum section are linked into dual-stage tandem with communicating pipe. The two segments are separated by intermediate wall (A)(7)and intermediate wall(B)(6) and the intermediate wall(B) has ingestion port. The 2SK collection two-phase pumps are mechanically sealed at the two finishes.

There is a drinking water inlet gap in the substantial degree vacuum section by way of which the make-up water is filled into the lengthier pump physique, even though the make-up water for minimal diploma vacuum phase is discharged from the high degree vacuum. (The make-up water for the lower diploma vacuum of 2SK-12A,2SK-20A and 2SK-30A are also partly provided from the water offer pipe but it require to be regulated through valves.) The higher and low diploma vacuum segments are secured together with draw-in bolt. The air injection pump consists of inlet air pipe, jet nozzle, air valve human body and diffuser.
