Doing work Concept

one. Series SK,2SK H2o Ring Vacuum Pumps can be employed to exhaust ordinary gases as effectively as condensable gases(this sort of as water vapor). Because they have the features of isothermal compression, they can exhaust flammable and explosive gases. When the pump made up of anti-corrosion content is picked, it can be utilised for exhausting corrosive gases as well. 


   2SK collection two-stage liquid ring vacuum pumps can function properly like two sets of SK series water ring vacuum pump. Owing to SK series vacuum pumps only get to the greatest vacuum of-700mmHg, to fulfill the higher vacuum and the large pumping speed below higher vacuum, China developed the 2SK series water ring vacuum pump in 80s in the twentieth century. 


2. Sequence 2YK Liquid Ring Vacuum Pumps have the functions of higher vacuum and greater applicability. The diverse varieties of gases can be pumped with the selected appropriate doing work media. As a result, they can be applied in broader selection.


three. The pumps run efficiently with reduced sound and consumption. The strength-saving is thirty p.c evaluating with the Water Jet and the H2o VaporJet Pumps.





one. Compared with SK drinking water vacuum pump ,It receives large vacuum and pumping pace and so on..

2. Basic structure and easy maintenance.

three. The mainly doing work medium is h2o and lower maintenance charges.

4.The pump is commonly use in many locations and suction drinking water vapor,flammable, explosive and various gases include a modest sum of dust and liquid.

five. The pump can functions in the severe 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
(one)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 between5×103~1.3×104Pa(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.

2,Working Media 
There are four principles to choose working media(i.e.ring liquids)
(one) 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.
(four) Economy

      If the h2o is picked as the functioning medium, the greatest temperature of source water must be lower than or equal to 15 °C the optimum one ought to not be increased than 40°C. Although the transformer oil or other low viscosity and saturated vapor force industrial oils are as the functioning media, the general supply temperature need to not larger than 40°C and the operating media temperature within the pump chamber should not be increased than 60C, when the liquid with lower boiling point is picked as the functioning media beneath some specific situations, the cooling device need to be geared up to amazing down the functioning media in buy to make certain that the max temperature is 30ºC-50ºC, lower than the boiling stage. For the closed circulated program of functioning media, the liquid storage unit and cooler need to be geared up, and the gasoline-liquid separator have to be installed at outlet. The mechanical seal should be utilised for dynamic seal of the shaft.


three,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:

(one) For the non anti-corrosion pump, the shaft is manufactured of 45#metal or 40Cr, other areas are manufactured of cast Iron or brass

(two) For the anti-corrosion pump,the areas that the gasoline passed, must be produced of stainless metal 304 and 306, or other material suitable for the respectively corrosive fuel, or the parts need to be place with anti-corrosion coating.

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

If the pump is used for vacuuming although transferring fuel, the pressure of pump outlet exceeds the CZPT ambiance force.

When the outlet pressure exceeds .15MPa, the unique double-levels liquid ring compressor should be selected and not the vacuum pump refitted. Tthe energy of the outfitted motor should be elevated naturally. And the special gasoline-liquid separator and car-drain unit should be geared up way too.

When the outlet stress is underneath .15MPa, it can use the vacuum pump refitted as compressor. The electrical power of the equipped motor need to be improved correctly.

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.
