High Vacuum Food Industry Drying Water Ring Pump


2SK sequence two-stage liquid ring vacuum pumps can operate effectively like two sets of SK sequence h2o ring vacuum pump. Because of to SK series vacuum pumps only achieve the maximum vacuum of-700mmHg, to fulfill the higher vacuum and the big pumping speed under higher vacuum, China designed the 2SK collection h2o ring vacuum pump in 80s in the 20th century. 


one. Compared with SK water vacuum pump ,It receives substantial vacuum and pumping speed and so on..

2. Straightforward structure and straightforward maintenance.

3. The largely functioning medium is h2o and lower upkeep fees.

4.The pump is extensively use in a lot of places and suction water vapor,flammable, explosive and a variety of gases contain a little volume of dust and liquid.

five. The pump can operates in the severe condition


one. Sequence SK,2SK H2o Ring Vacuum Pumps can be utilised to exhaust ordinary gases as effectively as condensable gases(this kind of as drinking water vapor). Since they have the features of isothermal compression, they can exhaust flammable and explosive gases. When the pump made up of anti-corrosion material is selected, it can be utilized for exhausting corrosive gases too.


2. Collection 2YK Liquid Ring Vacuum Pumps have the features of increased vacuum and better applicability. The diverse varieties of gases can be pumped with the chosen suitable working media. For that reason, they can be used in wider variety.


3. The pumps operate smoothly with minimal noise and usage. The energy-conserving is 30 p.c comparing with the H2o Jet and the 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)
(1) Lower saturated steam pressure
(2) 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 drinking water is selected as the working medium, the ideal temperature of offer drinking water need to be reduced than or equivalent to fifteen °C the maximum 1 ought to not be increased than 40°C. Although the transformer oil or other low viscosity and saturated vapor strain industrial oils are as the functioning media, the basic supply temperature must not larger than 40°C and the functioning media temperature inside of the pump chamber must not be greater than 60C, when the liquid with lower boiling position is picked as the functioning media below some particular situation, the cooling unit have to be outfitted to awesome down the operating media in buy to guarantee that the max temperature is 30ºC-50ºC, lower than the boiling point. For the closed circulated method of functioning media, the liquid storage unit and cooler have to be equipped, and the gasoline-liquid separator have to be put in at outlet. The mechanical seal should be employed 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#metal or 40Cr, other elements are produced of forged Iron or brass

(two) For the anti-corrosion pump,the elements that the gasoline passed, need to be created of stainless metal 304 and 306, or other material ideal for the respectively corrosive fuel, or the elements must be set with anti-corrosion coating.

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

If the pump is utilised for vacuuming although transferring fuel, the force of pump outlet exceeds the common ambiance stress.

When the outlet strain exceeds .15MPa, the special double-stages liquid ring compressor ought to be picked and not the vacuum pump refitted. Tthe power of the equipped motor must be improved obviously. And the specific gas-liquid separator and vehicle-drain device need to be geared up way too.

When the outlet stress is below .15MPa, it can use the vacuum pump refitted as compressor. The electricity of the geared up motor should be elevated effectively.

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.
