Working Principle

one. Sequence SK,2SK H2o Ring Vacuum Pumps can be used to exhaust common gases as properly as condensable gases(such as h2o vapor). Because they have the functions of isothermal compression, they can exhaust flammable and explosive gases. When the pump created up of anti-corrosion content is picked, it can be employed for exhausting corrosive gases way too. 


   2SK series two-phase liquid ring vacuum pumps can perform nicely like two sets of SK collection water ring vacuum pump. Due to SK series vacuum pumps only attain the maximum vacuum of-700mmHg, to meet up with the large vacuum and the large pumping pace beneath large vacuum, China produced the 2SK sequence h2o ring vacuum pump in 80s in the twentieth century. 


two. Collection 2YK Liquid Ring Vacuum Pumps have the characteristics of larger vacuum and better applicability. The various sorts of gases can be pumped with the selected appropriate working media. For that reason, they can be applied in wider range.


3. The pumps run effortlessly with minimal noise and use. The vitality-conserving is thirty % evaluating with the Drinking water Jet and the Drinking water VaporJet Pumps.





one. Compared with SK water vacuum pump ,It gets substantial vacuum and pumping speed and so on..

2. Basic construction and easy upkeep.

3. The primarily functioning medium is water and reduced servicing fees.

four.The pump is broadly use in several places and suction drinking water vapor,flammable, explosive and a variety of gases contain a little volume of dust and liquid.

five. The pump can operates in the severe situation

one. Compared with SK drinking water vacuum pump ,It will get higher vacuum and pumping velocity and so forth..

2. Simple construction and effortless servicing.

3. The largely functioning medium is drinking water and minimal upkeep expenses.

four.The pump is extensively use in many regions and suction h2o vapor,flammable, explosive and various gases have a small sum of dust and liquid.

5. The pump can operates in the harsh issue

Regular Selection for Water(Liquid)Ring Vacuum Pump

one,Based on the vacuum value
(1)If the pump is operated for long time with the inlet pressure range between1.3×104~1×105Pa (between 100 and 760 Torr), please choose series SK Water Ring Vacuum Pump.
(two)If the pump is operated for long time with the inlet pressure range between5×103~one.3×104Pa(between40 and 100 Torr), please choose series 2SK Water Ring Vacuum Pump.
(3)If the pump is operated for long time with the inlet pressure range between1×103~1.3×104Pa(between8 and 100 Torr), please choose series 2YK Liquid Ring Vacuum Pump.

two,Working Media 
There are four principles to choose working media(i.e.ring liquids)
(1) Lower saturated steam pressure
(two) Lower viscosity
(3) Stable physical & chemical features no chemical reaction with the pumped gasno corrosion to the pump no pollution to the environment.
(4) Economy

      If the h2o is chosen as the operating medium, the ideal temperature of offer drinking water ought to be lower than or equal to 15 °C the maximum one should not be larger than 40°C. Even though the transformer oil or other reduced viscosity and saturated vapor force industrial oils are as the working media, the standard provide temperature ought to not larger than 40°C and the working media temperature inside of the pump chamber must not be greater than 60C, when the liquid with lower boiling position is picked as the working media underneath some particular circumstances, the cooling device need to be equipped to awesome down the functioning media in order to make certain that the max temperature is 30ºC-50ºC, lower than the boiling stage. For the shut circulated technique of working media, the liquid storage device and cooler have to be outfitted, and the fuel-liquid separator must be set up at outlet. The mechanical seal should be employed for dynamic seal of the shaft.

3,Choose the dynamic seal of the shaft:
Choose the packing seal in general occasion choose the mechanical seal when the pump is used in no leak occasion.

four,Choose the material of the part that the gas passed:

(1) For the non anti-corrosion pump, the shaft is created of 45#metal or 40Cr, other parts are produced of solid Iron or brass

(2) For the anti-corrosion pump,the areas that the fuel handed, must be manufactured of stainless steel 304 and 306, or other substance appropriate for the respectively corrosive gasoline, or the elements need to be place with anti-corrosion coating.

five, The motor should be selected based on pumping pressure.

If the pump is utilized for vacuuming while transferring gas, the strain of pump outlet exceeds the CZPT atmosphere force.

When the outlet pressure exceeds .15MPa, the special double-levels liquid ring compressor need to be selected and not the vacuum pump refitted. Tthe power of the equipped motor need to be improved obviously. And the unique fuel-liquid separator and automobile-drain device should be equipped also.

When the outlet pressure is underneath .15MPa, it can use the vacuum pump refitted as compressor. The energy of the equipped motor need to be improved appropriately.

6,Composition methods of the water ring vacuum pump system
The opening circulation system should be used if the working liquid in the outlet need not be circulated or partially circulated.
The closed circulation system should be used if the working liquid in the outlet must be circulated.

Broadly employed in papermaking, chemical, petrochemical, light-weight business, pharmaceutical, meals, creating materials, electrical appliances, coal washing and  mineral dressing industry, fertilizer, and many others. 
In the coal business, it can specifically pump very flammable and explosive fuel, this kind of as mash gasoline, methane, can design and style set up of ground fuel drainage station, can kind a comprehensive established of cellular fuel drainage program.
