Sk-25 Single Stage Water Ring Vacuum Degassing Pump

Sk-25 Single Stage Water Ring Vacuum Degassing Pump


2SK sequence two-phase liquid ring vacuum pumps can work properly like two sets of SK sequence h2o ring vacuum pump. Owing to SK series vacuum pumps only attain the highest vacuum of-700mmHg, to meet up with the substantial vacuum and the large pumping speed under large vacuum, China developed the 2SK sequence drinking water ring vacuum pump in 80s in the twentieth century. 


one. Compared with SK drinking water vacuum pump ,It receives large vacuum and pumping velocity etc..

2. Straightforward composition and simple routine maintenance.

three. The primarily operating medium is drinking water and reduced servicing expenses.

4.The pump is broadly use in several areas and suction water vapor,flammable, explosive and different gases include a little amount of dust and liquid.

five. The pump can performs in the severe issue


1. Collection SK,2SK Water Ring Vacuum Pumps can be utilized to exhaust regular gases as well as condensable gases(this kind of as water vapor). Because they have the features of isothermal compression, they can exhaust flammable and explosive gases. When the pump created 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 attributes of larger vacuum and much better applicability. The distinct types of gases can be pumped with the chosen suitable working media. As a result, they can be applied in wider variety.


three. The pumps operate efficiently with minimal sounds and intake. The power-conserving is thirty p.c comparing with the Water 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
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~one.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~one.3×104Pa(between8 and 100 Torr), please choose series 2YK Liquid Ring Vacuum Pump.

2,Working Media 
There are four principles to choose working media(i.e.ring liquids)
(one) 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 water is selected as the doing work medium, the greatest temperature of provide h2o should be reduced than or equal to fifteen °C the greatest 1 ought to not be higher than 40°C. Even though the transformer oil or other low viscosity and saturated vapor strain industrial oils are as the working media, the basic provide temperature must not greater than 40°C and the operating media temperature inside of the pump chamber need to not be larger than 60C, when the liquid with reduced boiling position is chosen as the doing work media beneath some specific situations, the cooling unit must be geared up to awesome down the functioning media in order to make certain that the max temperature is 30ºC-50ºC, reduced than the boiling point. For the shut circulated method of functioning media, the liquid storage unit and cooler should be geared up, and the gasoline-liquid separator must 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 manufactured of 45#metal or 40Cr, other components are created of forged Iron or brass

(2) For the anti-corrosion pump,the areas that the gas handed, need to be made of stainless metal 304 and 306, or other substance suitable for the respectively corrosive gasoline, or the areas must be put with anti-corrosion coating.

five, 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 strain.

When the outlet strain exceeds .15MPa, the particular double-phases liquid ring compressor need to be selected and not the vacuum pump refitted. Tthe energy of the outfitted motor ought to be improved naturally. And the unique fuel-liquid separator and car-drain device must be geared up also.

When the outlet force is beneath .15MPa, it can use the vacuum pump refitted as compressor. The energy of the outfitted motor need to be increased 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.
