Liquid Ring Vacuum Vaporizing Pumps

Liquid Ring Vacuum Vaporizing Pumps


2SK sequence two-stage liquid ring vacuum pumps can work effectively like two sets of SK series h2o ring vacuum pump. Due to SK sequence vacuum pumps only get to the maximum vacuum of-700mmHg, to meet up with the high vacuum and the huge pumping speed under substantial vacuum, China developed the 2SK sequence h2o ring vacuum pump in 80s in the 20th century. 


one. In comparison with SK water vacuum pump ,It gets high vacuum and pumping velocity etc..

two. Simple construction and easy upkeep.

three. The largely operating medium is drinking water and reduced servicing costs.

4.The pump is broadly use in a lot of places and suction h2o vapor,flammable, explosive and numerous gases contain a tiny volume of dust and liquid.

5. The pump can operates in the harsh situation


1. Sequence SK,2SK H2o Ring Vacuum Pumps can be utilised to exhaust common gases as properly as condensable gases(such as water vapor). Simply because they have the features of isothermal compression, they can exhaust flammable and explosive gases. When the pump made up of anti-corrosion materials is picked, it can be used for exhausting corrosive gases way too.


two. Collection 2YK Liquid Ring Vacuum Pumps have the functions of greater vacuum and greater applicability. The distinct kinds of gases can be pumped with the chosen ideal doing work media. Consequently, they can be used in broader assortment.


three. The pumps run efficiently with lower sounds and intake. The strength-saving is thirty per cent evaluating with the H2o Jet and the Drinking water Vapor Jet Pumps.

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
one,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.
(three)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.

2,Working Media 
There are four principles to choose working media(i.e.ring liquids)
(1) Lower saturated steam pressure
(2) 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 selected as the operating medium, the very best temperature of source h2o need to be decrease than or equivalent to fifteen °C the optimum one must not be greater than 40°C. Even though the transformer oil or other low viscosity and saturated vapor stress industrial oils are as the operating media, the general provide temperature must not larger than 40°C and the doing work media temperature within the pump chamber should not be greater than 60C, when the liquid with reduced boiling stage is chosen as the operating media below some particular situation, the cooling unit must be geared up to cool down the functioning media in buy to make certain that the max temperature is 30ºC-50ºC, reduce than the boiling position. For the closed circulated technique of functioning media, the liquid storage unit and cooler need to be equipped, and the gas-liquid separator have to be put in at outlet. The mechanical seal ought to be used 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:

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

(2) For the anti-corrosion pump,the parts that the gas passed, should be made of stainless metal 304 and 306, or other materials appropriate for the respectively corrosive gasoline, or the areas must be set with anti-corrosion coating.

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

If the pump is utilised for vacuuming even though transferring fuel, the pressure of pump outlet exceeds the CZPT atmosphere pressure.

When the outlet force exceeds .15MPa, the unique double-stages liquid ring compressor must be chosen and not the vacuum pump refitted. Tthe electricity of the geared up motor should be improved obviously. And the unique fuel-liquid separator and vehicle-drain unit should be geared up way too.

When the outlet strain is under .15MPa, it can use the vacuum pump refitted as compressor. The power of the outfitted motor need to be enhanced properly.

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.
