Motor Direct Connection Type Water Ring Vacuum Pump

Motor Direct Connection Type Water Ring Vacuum Pump


2SK series two-phase liquid ring vacuum pumps can function well like two sets of SK sequence drinking water ring vacuum pump. Due to SK collection vacuum pumps only attain the optimum vacuum of-700mmHg, to meet up with the higher vacuum and the massive pumping velocity below substantial vacuum, China produced the 2SK collection drinking water ring vacuum pump in 80s in the 20th century. 


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

two. Straightforward composition and effortless routine maintenance.

3. The largely operating medium is water and lower maintenance fees.

four.The pump is extensively use in numerous locations and suction water vapor,flammable, explosive and a variety of gases contain a small volume of dust and liquid.

5. The pump can performs in the severe problem


1. Collection SK,2SK Water Ring Vacuum Pumps can be utilised to exhaust normal gases as properly as condensable gases(this sort of as h2o vapor). Since they have the features of isothermal compression, they can exhaust flammable and explosive gases. When the pump manufactured up of anti-corrosion materials is selected, it can be used for exhausting corrosive gases as well.


2. Collection 2YK Liquid Ring Vacuum Pumps have the functions of increased vacuum and much better applicability. The distinct kinds of gases can be pumped with the chosen appropriate working media. Therefore, they can be applied in broader variety.


three. The pumps run efficiently with reduced sounds and use. The vitality-preserving is 30 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
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 between5×103~1.3×104Pa(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)
(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 chosen as the doing work medium, the very best temperature of supply drinking water should be reduce than or equivalent to 15 °C the maximum 1 ought to not be higher than 40°C. Whilst the transformer oil or other minimal viscosity and saturated vapor pressure industrial oils are as the functioning media, the general supply temperature must not higher than 40°C and the operating media temperature inside of the pump chamber need to not be increased than 60C, when the liquid with lower boiling point is chosen as the functioning media beneath some special situation, the cooling unit must be outfitted to awesome down the functioning media in get to guarantee that the max temperature is 30ºC-50ºC, reduced than the boiling point. For the shut circulated method of doing work media, the liquid storage device and cooler need to be equipped, and the fuel-liquid separator should be put in at outlet. The mechanical seal should 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.

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 parts are produced of cast Iron or brass

(two) For the anti-corrosion pump,the components that the fuel passed, need to be created of stainless metal 304 and 306, or other substance suitable for the respectively corrosive fuel, or the components should be set with anti-corrosion coating.

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

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

When the outlet stress exceeds .15MPa, the special double-levels liquid ring compressor ought to be chosen and not the vacuum pump refitted. Tthe electricity of the equipped motor need to be improved naturally. And the specific gas-liquid separator and vehicle-drain device need to be geared up as well.

When the outlet pressure is beneath .15MPa, it can use the vacuum pump refitted as compressor. The energy of the outfitted motor should be improved 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.
