2sk-6 Two Stage Water Ring Vacuum Pump

2SK Pump description:

2SK collection two-stage drinking water ring vacuum pump and 2SK- P1 series two-stage drinking water ring vacuum pump---air injection pump unit are vacuum pumps and vacuum device with higher diploma of vacuum, higher evacuation speed in higher vacuum intervals, compact building, reputable software, and simple assembly and disassembly which created according with stipulations of Designs and Fundamental Parameter of JB/TQ354-eighty four(H2o Ring Vacuum Pump and Drinking water Ring Air CZPT).

This device is made up of one particular-stage air injection pump and two-phase drinking water ring vacuum pump which can be used independently if client needed.

This two-phase water ring vacuum pump or unit is applicable for pumping air and other non-corrosive fuel which is insoluble in drinking water and with no containing solid particles so as to obtain substantial vacuum in sealed vessel.

Functioning Basic principle:

The functioning principle of two-phase drinking water ring vacuum pump is illustrated in the following Determine. When the eccentrically-assembled impellers(5) in the pump body (3) rotate, drinking water is thrown off outwards because of to the centrifugal drive .This will sort a rotating h2o ring(6) amongst the within area of pump human body and the impeller. Then the within area of water ring will contact impeller hub. When the impeller hub rotates clockwise, the inside of surface of the water ring breaks away steadily from the hub during the first 50 percent turn and the cavity between two adjacent impellers expand slowly thus the pumped gasoline is drawn into the cavity via crescent suction hole(7) by way of pump inlet air pipe(4) throughout the CZPT half change, the within area of h2o ring approaches the impeller hub gradually and the cavity among two adjacent impellers shrink steadily with the fuel compressed and the force of which preserve decreasing and air got expelled. When the interior stress override the force of the external pressure, the gas within the vessel is evacuated progressively ,so it will acquire vacuum.


Air injection pump is a kind of jet injector, the operating basic principle of which is as follows: specific diploma of vacuum within the evacuated container is formed owing to the operation of the two-phase drinking water 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 swiftly due to the wonderful force distinction in between the air (or pressurized gases) and the intake pipe. Right after the spout of the air, the stream price is accelerated, so the stress reduces, in this way it will obtain higher vacuum diploma of the spout(remarkably higher than the vacuum diploma of pump),then it carries on to draw fuel into the pump.


The structural drawings of two-phase water ring vacuum pump with capacity in excess of one.5mthree/min is illustrated in the figure two, the more time impeller(seventeen) and the shorter impeller(sixteen) are mounted to the shaft(2) with pins, and between the two impellers, it is mounted by shaft sleeve(twenty) and locked with round nut so it forms rotor. The two impellers eccentrically mounted inside of the pump physique and supported by two one row radial ball bearings. The rotor is connected to motor shaft with coupling(18) and rotates with each other with the motor. CZPT impeller(seventeen),more time pump human body(9) and the suction element types large vacuum degree shorter pump physique(five),shorter impeller(sixteen)and the discharge component types minimal vacuum diploma. The air outlet of higher degree vacuum section and the suction inlet of lower diploma vacuum section are related into dual-stage tandem with communicating pipe. The two segments are separated by intermediate wall (A)(7)and intermediate wall(B)(six) and the intermediate wall(B) has ingestion port. The 2SK series two-phase pumps are mechanically sealed at equally finishes.

There is a water inlet hole in the large diploma vacuum section by way of which the make-up drinking water is stuffed into the longer pump entire body, even though the make-up water for reduced diploma vacuum section is discharged from the higher diploma vacuum. (The make-up h2o for the lower degree vacuum of 2SK-12A,2SK-20A and 2SK-30A are also partly provided from the h2o supply pipe but it need to have to be controlled via valves.) The substantial and minimal degree vacuum segments are secured together with attract-in bolt. The air injection pump consists of inlet air pipe, jet nozzle, air valve human body and diffuser.
