2sk Double Stage Liquid/Water Ring Vacuum Pump

2SK Pump description:

2SK series two-stage water ring vacuum pump and 2SK- P₁ series two-stage water ring vacuum pump---air injection pump unit are vacuum pumps and vacuum unit with high degree of vacuum, high evacuation speed in high vacuum intervals, compact construction, reliable application, and easy assembly and disassembly which developed according with stipulations of Patterns and Basic Parameter of JB/TQ354-84(Water Ring Vacuum Pump and Water Ring Air Compressor).

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

This two-stage water ring vacuum pump or unit is applicable for pumping air and other non-corrosive gas which is insoluble in water and without containing solid particles so as to acquire high vacuum in sealed vessel.
 

Working Principle:

The working principle of two-stage water ring vacuum pump is illustrated in the following Figure. When the eccentrically-assembled impellers(5) in the pump body (3) rotate, water is thrown off outwards due to the centrifugal force .This will form a rotating water ring(6) between the inside surface of pump body and the impeller. Then the inside surface of water ring will contact impeller hub. When the impeller hub rotates clockwise, the inside surface of the water ring breaks away gradually from the hub during the first half turn and the cavity between two adjacent impellers grow gradually thus the pumped gas is drawn into the cavity through crescent suction hole(7) via pump inlet air pipe(4); during the second half turn, the inside surface of water ring approaches the impeller hub gradually and the cavity between two adjacent impellers shrink gradually with the gas compressed and the pressure of which keep decreasing and air got expelled. When the internal pressure override the pressure of the external pressure, the gas inside the vessel is evacuated gradually ,so it will acquire vacuum.


 

Air injection pump is a kind of jet injector, the working principle of which is as follows: certain degree of vacuum inside the evacuated container is formed due to the operation of the two-stage 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 rapidly due to the great pressure difference between the air (or pressurized gases) and the intake pipe. After the spout of the air, the flow rate is accelerated, so the pressure reduces, in this way it will acquire high vacuum degree of the spout(remarkably higher than the vacuum degree of pump),then it continues to draw gas into the pump.

The structural drawings of two-stage water ring vacuum pump with capacity over 1.5m³/min is illustrated in the figure 2, the longer impeller(17) and the shorter impeller(16) are fixed to the shaft(2) with pins, and between the two impellers, it is fixed by shaft sleeve(20) and locked with round nut so it forms rotor. The two impellers eccentrically installed inside the pump body and supported by two single row radial ball bearings. The rotor is connected to motor shaft with coupling(18) and rotates together with the motor. Longer impeller(17),longer pump body(9) and the suction part forms high vacuum degree; shorter pump body(5),shorter impeller(16)and the discharge part forms low vacuum degree. The air outlet of high degree vacuum segment and the suction inlet of low degree vacuum segment are connected 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 intake port. The 2SK series two-stage pumps are mechanically sealed at both ends.

There is a water inlet hole in the high degree vacuum segment through which the make-up water is filled into the longer pump body, while the make-up water for low degree vacuum segment is discharged from the high degree vacuum. (The make-up water for the low degree vacuum of 2SK-12A,2SK-20A and 2SK-30A are also partly supplied from the water supply pipe but it need to be regulated through valves.) The high and low degree vacuum segments are secured together with draw-in bolt. The air injection pump consists of inlet air pipe, jet nozzle, air valve body and diffuser.

The main function of an Air Dryer is to remove moisture from the air by cooling it with refrigerant. And then the water is condensed, and the air can be compressed. The result is dry compressed air, which can be used in compressed air equipment without causing any damage
