Operating Concept

one. Sequence SK,2SK Drinking water Ring Vacuum Pumps can be utilized to exhaust normal gases as nicely as condensable gases(such as water vapor). Simply because they have the attributes of isothermal compression, they can exhaust flammable and explosive gases. When the pump manufactured up of anti-corrosion substance is chosen, it can be employed for exhausting corrosive gases as well. 


   2SK series two-phase liquid ring vacuum pumps can work nicely like two sets of SK sequence drinking water ring vacuum pump. Due to SK sequence vacuum pumps only get to the maximum vacuum of-700mmHg, to fulfill the high vacuum and the big pumping speed beneath higher vacuum, China created the 2SK series water ring vacuum pump in 80s in the twentieth century. 


2. Series 2YK Liquid Ring Vacuum Pumps have the features of increased vacuum and greater applicability. The various sorts of gases can be pumped with the selected suited doing work media. Consequently, they can be applied in broader variety.


3. The pumps operate smoothly with minimal sound and use. The strength-preserving is thirty per cent evaluating with the H2o Jet and the H2o VaporJet Pumps.





one. When compared with SK water vacuum pump ,It gets large vacuum and pumping speed and many others..

2. Basic construction and simple routine maintenance.

three. The primarily working medium is drinking water and minimal maintenance costs.

four.The pump is commonly use in several regions and suction water vapor,flammable, explosive and numerous gases include a tiny sum of dust and liquid.

5. The pump can functions in the harsh problem

It can be applied to the vacuum drying, vacuum degassing, vacuum concentration, vacuum evaporation, vacuum impregnation process in chemical, pharmaceutical, metallurgy, food, medicine, textile, papermaking, electrical industry ( electronic industrial field) and so on. It can compose a vacuum system together with Roots Vacuum Pump and atmospheric Jet pump to achieve high vacuum, high efficiency, low power consumption.



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.
(2)If the pump is operated for long time with the inlet pressure range between5×103~1.3×104Pa(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~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)
(1) Lower saturated steam pressure
(2) 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 water is selected as the operating medium, the greatest temperature of provide h2o ought to be reduced than or equal to fifteen °C the greatest one particular ought to not be greater than 40°C. Even though the transformer oil or other reduced viscosity and saturated vapor stress industrial oils are as the operating media, the basic supply temperature must not larger than 40°C and the operating media temperature inside of the pump chamber must not be larger than 60C, when the liquid with reduced boiling point is selected as the operating media underneath some particular situation, the cooling device must be outfitted to awesome down the working media in order to ensure that the max temperature is 30ºC-50ºC, reduced than the boiling stage. For the shut circulated method of operating media, the liquid storage unit and cooler have to be equipped, and the fuel-liquid separator need to be put in at outlet. The mechanical seal must be utilized 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:

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

(2) For the anti-corrosion pump,the components that the gas handed, ought to be created of stainless metal 304 and 306, or other material suitable for the respectively corrosive fuel, or the parts must be set with anti-corrosion coating.

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

If the pump is employed for vacuuming whilst transferring gas, the stress of pump outlet exceeds the CZPT atmosphere stress.

When the outlet strain exceeds .15MPa, the unique double-stages liquid ring compressor ought to be selected and not the vacuum pump refitted. Tthe power of the outfitted motor must be increased obviously. And the special fuel-liquid separator and automobile-drain device need to be geared up way too.

When the outlet pressure is below .15MPa, it can use the vacuum pump refitted as compressor. The power of the outfitted motor should be increased 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.
