2sk-3 Two Stage Liquid Ring Vacuum Pump

2sk-3 Two Stage Liquid Ring Vacuum Pump

2SK Pump description:

2SK series two-stage drinking water ring vacuum pump and 2SK- Pone series two-stage drinking water ring vacuum pump—air injection pump device are vacuum pumps and vacuum device with large degree of vacuum, higher evacuation velocity in substantial vacuum intervals, compact design, reliable software, and easy assembly and disassembly which produced in accordance with stipulations of Styles and Standard Parameter of JB/TQ354-84(Drinking water Ring Vacuum Pump and Water Ring Air CZPT).

This unit consists of 1-stage air injection pump and two-stage drinking water ring vacuum pump which can be utilized separately if client required.

This two-stage drinking water ring vacuum pump or unit is relevant for pumping air and other non-corrosive gas which is insoluble in drinking water and without having that contains solid particles so as to get substantial vacuum in sealed vessel.

Operating Principle:

The working principle of two-phase drinking water ring vacuum pump is illustrated in the following Determine. When the eccentrically-assembled impellers(five) in the pump human body (three) rotate, water is thrown off outwards because of to the centrifugal power .This will type a rotating h2o ring(six) among the inside of area of pump human body and the impeller. Then the inside area of drinking water ring will speak to impeller hub. When the impeller hub rotates clockwise, the inside of surface area of the h2o ring breaks absent slowly from the hub for the duration of the first half switch and the cavity in between two adjacent impellers increase progressively hence the pumped gasoline is drawn into the cavity via crescent suction gap(7) by way of pump inlet air pipe(4) for the duration of the CZPT fifty percent switch, the within surface of h2o ring ways the impeller hub steadily and the cavity among two adjacent impellers shrink progressively with the fuel compressed and the pressure of which keep reducing and air acquired expelled. When the interior strain override the stress of the exterior stress, the gasoline inside of the vessel is evacuated steadily ,so it will purchase vacuum.


Air injection pump is a kind of jet injector, the doing work principle of which is as follows: certain diploma of vacuum within the evacuated container is formed owing to the operation of the two-stage drinking water 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 rapidly thanks to the great stress distinction between the air (or pressurized gases) and the ingestion pipe. Soon after the spout of the air, the stream price is accelerated, so the pressure lowers, in this way it will purchase substantial vacuum diploma of the spout(remarkably increased than the vacuum degree of pump),then it proceeds to attract gasoline into the pump.


The structural drawings of two-stage h2o ring vacuum pump with capacity over one.5m3/min is illustrated in the determine 2, the more time impeller(seventeen) and the shorter impeller(sixteen) are mounted to the shaft(2) with pins, and among the two impellers, it is mounted by shaft sleeve(20) and locked with spherical nut so it types rotor. The two impellers eccentrically installed inside the pump body and supported by two one row radial ball bearings. The rotor is connected to motor shaft with coupling(eighteen) and rotates jointly with the motor. CZPT impeller(17),for a longer time pump human body(nine) and the suction element forms large vacuum diploma shorter pump body(5),shorter impeller(sixteen)and the discharge element kinds reduced vacuum diploma. The air outlet of substantial degree vacuum section and the suction inlet of minimal diploma vacuum segment are connected into twin-stage tandem with speaking pipe. The two segments are divided by intermediate wall (A)(seven)and intermediate wall(B)(six) and the intermediate wall(B) has consumption port. The 2SK sequence two-stage pumps are mechanically sealed at the two ends.

There is a drinking water inlet gap in the higher diploma vacuum section by way of which the make-up h2o is crammed into the more time pump body, even though the make-up drinking water for low degree vacuum segment is discharged from the higher degree vacuum. (The make-up water for the lower diploma vacuum of 2SK-12A,2SK-20A and 2SK-30A are also partly equipped from the h2o offer pipe but it need to have to be regulated via valves.) The large and lower diploma vacuum segments are secured jointly with draw-in bolt. The air injection pump is made up of inlet air pipe, jet nozzle, air valve physique and diffuser.
