Liquid Ring Vacuum Concentration Pump

Liquid Ring Vacuum Concentration Pump


2SK sequence two-phase liquid ring vacuum pumps can operate well like two sets of SK series h2o ring vacuum pump. Owing to SK collection vacuum pumps only reach the maximum vacuum of-700mmHg, to meet up with the high vacuum and the massive pumping velocity beneath large vacuum, China designed the 2SK sequence water ring vacuum pump in 80s in the 20th century. 


1. In contrast with SK water vacuum pump ,It gets large vacuum and pumping speed and so forth..

2. Basic construction and simple upkeep.

3. The largely operating medium is drinking water and minimal maintenance fees.

4.The pump is extensively use in several places and suction h2o vapor,flammable, explosive and a variety of gases include a modest sum of dust and liquid.

5. The pump can works in the severe condition


1. Series SK,2SK Drinking water Ring Vacuum Pumps can be used to exhaust ordinary gases as properly as condensable gases(such as water vapor). Because they have the features of isothermal compression, they can exhaust flammable and explosive gases. When the pump produced up of anti-corrosion material is chosen, it can be utilised for exhausting corrosive gases also.


two. Collection 2YK Liquid Ring Vacuum Pumps have the characteristics of increased vacuum and far better applicability. The diverse types of gases can be pumped with the chosen suitable functioning media. Therefore, they can be utilized in broader assortment.


3. The pumps operate easily with reduced sound and intake. The energy-saving is thirty p.c comparing with the Drinking water 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.

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.
(four) Economy

      If the water is selected as the working medium, the very best temperature of source h2o should be decrease than or equivalent to 15 °C the highest 1 should not be greater than 40°C. While the transformer oil or other low viscosity and saturated vapor pressure industrial oils are as the operating media, the common provide temperature ought to not greater than 40°C and the operating media temperature inside of the pump chamber should not be greater than 60C, when the liquid with decrease boiling stage is picked as the functioning media underneath some specific situations, the cooling unit have to be geared up to great down the operating media in buy to guarantee that the max temperature is 30ºC-50ºC, decrease than the boiling level. For the shut circulated system of functioning media, the liquid storage device and cooler should be outfitted, and the gasoline-liquid separator should be set up 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.

four,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 areas are produced of forged Iron or brass

(2) For the anti-corrosion pump,the components that the fuel passed, need to be created of stainless steel 304 and 306, or other materials appropriate for the respectively corrosive gasoline, or the components should be set with anti-corrosion coating.

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

If the pump is employed for vacuuming while transferring fuel, the stress of pump outlet exceeds the CZPT ambiance stress.

When the outlet strain exceeds .15MPa, the specific double-levels liquid ring compressor ought to be decided on and not the vacuum pump refitted. Tthe power of the outfitted motor should be increased clearly. And the special gasoline-liquid separator and vehicle-drain device should be geared up too.

When the outlet pressure is below .15MPa, it can use the vacuum pump refitted as compressor. The electricity of the geared up motor need to 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.
