Working Principle

1. Collection SK,2SK H2o Ring Vacuum Pumps can be employed to exhaust ordinary gases as well as condensable gases(such as drinking water vapor). Since they have the functions of isothermal compression, they can exhaust flammable and explosive gases. When the pump made up of anti-corrosion materials is chosen, it can be employed for exhausting corrosive gases way too. 


   2SK sequence two-phase liquid ring vacuum pumps can operate effectively like two sets of SK sequence drinking water ring vacuum pump. Because of to SK collection vacuum pumps only get to the maximum vacuum of-700mmHg, to satisfy the substantial vacuum and the huge pumping pace beneath high vacuum, China produced the 2SK series h2o ring vacuum pump in 80s in the twentieth century. 


two. Sequence 2YK Liquid Ring Vacuum Pumps have the functions of larger vacuum and better applicability. The distinct varieties of gases can be pumped with the selected suitable doing work media. Therefore, they can be applied in broader selection.


three. The pumps operate easily with lower sound and use. The strength-saving is 30 p.c evaluating with the Drinking water Jet and the Water VaporJet Pumps.





1. Compared with SK drinking water vacuum pump ,It receives high vacuum and pumping speed etc..

2. Basic composition and easy routine maintenance.

three. The largely working medium is water and low maintenance fees.

4.The pump is widely use in numerous places and suction water vapor,flammable, explosive and numerous gases have a small sum of dust and liquid.

five. The pump can operates in the harsh problem

one. Compared with SK h2o vacuum pump ,It gets large vacuum and pumping speed and many others..

2. Basic structure and straightforward maintenance.

3. The primarily working medium is h2o and reduced maintenance expenses.

4.The pump is extensively use in many areas and suction h2o vapor,flammable, explosive and various gases contain a modest amount of dust and liquid.

five. The pump can performs in the severe situation

Regular Selection for Water(Liquid)Ring Vacuum Pump

1,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.
(three)If the pump is operated for long time with the inlet pressure range between1×103~one.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)
(one) Lower saturated steam pressure
(two) Lower viscosity
(three) Stable physical & chemical features no chemical reaction with the pumped gasno corrosion to the pump no pollution to the environment.
(four) Economy

      If the drinking water is chosen as the operating medium, the greatest temperature of supply h2o need to be lower than or equivalent to 15 °C the highest a single ought to not be larger than 40°C. Even though the transformer oil or other low viscosity and saturated vapor force industrial oils are as the operating media, the basic provide temperature should not greater than 40°C and the operating media temperature inside of the pump chamber should not be larger than 60C, when the liquid with decrease boiling stage is picked as the functioning media under some special circumstances, the cooling unit have to be geared up to cool down the working media in get to guarantee that the max temperature is 30ºC-50ºC, decrease than the boiling point. For the closed circulated program of working media, the liquid storage unit and cooler must be outfitted, and the gasoline-liquid separator have to be set up at outlet. The mechanical seal need to be used 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.

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

(one) For the non anti-corrosion pump, the shaft is made of forty five#steel or 40Cr, other elements are created of cast Iron or brass

(2) For the anti-corrosion pump,the areas that the gasoline passed, must be made of stainless steel 304 and 306, or other materials suitable for the respectively corrosive gas, or the areas ought to be place with anti-corrosion coating.

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

If the pump is utilized for vacuuming even though transferring gas, the pressure of pump outlet exceeds the CZPT environment force.

When the outlet pressure exceeds .15MPa, the special double-phases liquid ring compressor need to be decided on and not the vacuum pump refitted. Tthe electrical power of the geared up motor need to be improved certainly. And the special gasoline-liquid separator and auto-drain device should be outfitted way too.

When the outlet stress is beneath .15MPa, it can use the vacuum pump refitted as compressor. The electricity of the outfitted motor need to be elevated appropriately.

six,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.

Widely employed in papermaking, chemical, petrochemical, mild industry, pharmaceutical, foods, building components, electrical appliances, coal washing and  mineral dressing industry, fertilizer, etc. 
In the coal market, it can specially pump hugely flammable and explosive gasoline, this sort of as mash gas, methane, can design installation of ground gas drainage station, can kind a complete established of mobile fuel drainage program.
