Liquid Ring Vacuum Pumps Used for Dehydrating Process


2SK sequence two-phase liquid ring vacuum pumps can operate well like two sets of SK sequence drinking water ring vacuum pump. Due to SK sequence vacuum pumps only attain the greatest vacuum of-700mmHg, to meet the higher vacuum and the huge pumping velocity underneath large vacuum, China designed the 2SK collection drinking water ring vacuum pump in 80s in the 20th century. 


one. In contrast with SK water vacuum pump ,It will get large vacuum and pumping velocity and so on..

2. Simple framework and easy routine maintenance.

three. The primarily operating medium is h2o and reduced routine maintenance expenses.

four.The pump is broadly use in a lot of places and suction water vapor,flammable, explosive and different gases contain a tiny sum of dust and liquid.

five. The pump can works in the harsh problem


1. Series SK,2SK Water Ring Vacuum Pumps can be employed to exhaust normal gases as effectively as condensable gases(this sort of as drinking water vapor). Since they have the attributes of isothermal compression, they can exhaust flammable and explosive gases. When the pump created up of anti-corrosion substance is picked, it can be used for exhausting corrosive gases too.


two. Series 2YK Liquid Ring Vacuum Pumps have the characteristics of higher vacuum and much better applicability. The different types of gases can be pumped with the picked appropriate working media. As a result, they can be applied in wider assortment.


3. The pumps run smoothly with minimal noise and intake. The strength-conserving is thirty p.c comparing with the 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
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.
(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)
(1) 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 picked as the doing work medium, the very best temperature of offer water must be lower than or equivalent to fifteen °C the optimum 1 ought to not be larger than 40°C. Although the transformer oil or other reduced viscosity and saturated vapor strain industrial oils are as the operating media, the standard supply temperature need to not increased than 40°C and the working media temperature inside of the pump chamber need to not be increased than 60C, when the liquid with reduce boiling position is selected as the functioning media underneath some particular situations, the cooling device should be outfitted to amazing down the working media in get to make certain that the max temperature is 30ºC-50ºC, decrease than the boiling level. For the shut circulated method of functioning media, the liquid storage device and cooler have to be geared up, and the gas-liquid separator need to be put in 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.

4,Choose the material of the part that the gas passed:

(1) For the non anti-corrosion pump, the shaft is manufactured of forty five#metal or 40Cr, other areas are produced of solid Iron or brass

(two) For the anti-corrosion pump,the parts that the gas passed, need to be created of stainless metal 304 and 306, or other materials suited for the respectively corrosive fuel, or the elements should be put with anti-corrosion coating.

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

If the pump is utilised for vacuuming whilst transferring gasoline, the force of pump outlet exceeds the normal environment strain.

When the outlet strain exceeds .15MPa, the unique double-levels liquid ring compressor should be chosen and not the vacuum pump refitted. Tthe electricity of the geared up motor ought to be enhanced naturally. And the special fuel-liquid separator and car-drain unit should be geared up way too.

When the outlet strain is beneath .15MPa, it can use the vacuum pump refitted as compressor. The electricity of the equipped motor must be improved correctly.

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.
