Water Ring Pump for Vacuum Concentration

Water Ring Pump for Vacuum Concentration


2SK series two-phase liquid ring vacuum pumps can operate nicely like two sets of SK sequence water ring vacuum pump. Because of to SK collection vacuum pumps only attain the greatest vacuum of-700mmHg, to fulfill the large vacuum and the big pumping pace below high vacuum, China produced the 2SK series h2o ring vacuum pump in 80s in the 20th century. 


1. In contrast with SK drinking water vacuum pump ,It gets high vacuum and pumping velocity and many others..

two. Easy framework and effortless routine maintenance.

3. The mainly doing work medium is water and low routine maintenance fees.

four.The pump is extensively use in several places and suction drinking water vapor,flammable, explosive and different gases incorporate a modest amount of dust and liquid.

five. The pump can operates in the harsh issue


1. Series SK,2SK Water Ring Vacuum Pumps can be utilised to exhaust regular gases as well as condensable gases(this sort of as drinking water vapor). Due to the fact they have the features of isothermal compression, they can exhaust flammable and explosive gases. When the pump manufactured up of anti-corrosion material is picked, it can be utilised for exhausting corrosive gases also.


two. Series 2YK Liquid Ring Vacuum Pumps have the features of larger vacuum and greater applicability. The distinct types of gases can be pumped with the selected suited functioning media. Consequently, they can be applied in wider selection.


three. The pumps operate easily with reduced noise and use. The energy-saving is thirty per cent comparing 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.
(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.
(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.

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.
(4) Economy

      If the h2o is chosen as the doing work medium, the greatest temperature of source drinking water ought to be decrease than or equivalent to fifteen °C the maximum 1 should not be increased than 40°C. Whilst the transformer oil or other low viscosity and saturated vapor stress industrial oils are as the functioning media, the general source temperature must not higher than 40°C and the operating media temperature inside of the pump chamber ought to not be greater than 60C, when the liquid with lower boiling position is picked as the functioning media under some unique conditions, the cooling unit have to be geared up to awesome down the doing work media in order to make certain that the max temperature is 30ºC-50ºC, reduced than the boiling point. For the closed circulated method of functioning media, the liquid storage unit and cooler must be equipped, and the gas-liquid separator should be put in 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 45#steel or 40Cr, other parts are created of cast Iron or brass

(2) For the anti-corrosion pump,the components that the fuel passed, ought to be produced of stainless steel 304 and 306, or other material ideal for the respectively corrosive gasoline, or the elements should be set with anti-corrosion coating.

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

If the pump is employed for vacuuming even though transferring gasoline, the strain of pump outlet exceeds the CZPT atmosphere stress.

When the outlet pressure exceeds .15MPa, the unique double-stages liquid ring compressor need to be chosen and not the vacuum pump refitted. Tthe power of the geared up motor ought to be elevated clearly. And the unique gas-liquid separator and automobile-drain device must be geared up also.

When the outlet strain is below .15MPa, it can use the vacuum pump refitted as compressor. The electrical power of the geared up motor must be increased 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.
