DESCRIPTION

2SK sequence two-stage liquid ring vacuum pumps can perform properly like two sets of SK sequence h2o ring vacuum pump. Thanks to SK collection vacuum pumps only reach the greatest vacuum of-700mmHg, to satisfy the high vacuum and the massive pumping pace beneath high vacuum, China created the 2SK sequence drinking water ring vacuum pump in 80s in the 20th century. 

 

Advantage

one. In comparison with SK water vacuum pump ,It will get substantial vacuum and pumping velocity etc..

two. Simple structure and straightforward maintenance.

three. The primarily working medium is h2o and low servicing charges.

four.The pump is broadly use in a lot of areas and suction drinking water vapor,flammable, explosive and numerous gases include a little quantity of dust and liquid.

5. The pump can performs in the severe issue

 

Attributes

1. Collection SK,2SK Drinking water Ring Vacuum Pumps can be utilized to exhaust normal gases as effectively as condensable gases(this kind of as water vapor). Due to the fact they have the attributes of isothermal compression, they can exhaust flammable and explosive gases. When the pump made up of anti-corrosion substance is selected, it can be utilised for exhausting corrosive gases too.

 

2. Sequence 2YK Liquid Ring Vacuum Pumps have the attributes of increased vacuum and much better applicability. The different varieties of gases can be pumped with the picked appropriate functioning media. Therefore, they can be applied in broader selection.

 

3. The pumps operate easily with minimal noise and use. The strength-conserving is 30 % comparing with the Drinking water Jet and the Drinking water Vapor Jet Pumps.

Software
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.
(2)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~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)
(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.
(four) Economy

      If the drinking water is selected as the doing work medium, the greatest temperature of provide water need to be decrease than or equivalent to fifteen °C the highest a single ought to not be larger than 40°C. Even though the transformer oil or other lower viscosity and saturated vapor stress industrial oils are as the functioning media, the common source temperature must not greater than 40°C and the operating media temperature inside of the pump chamber must not be greater than 60C, when the liquid with reduced boiling level is chosen as the functioning media under some specific circumstances, the cooling unit have to be geared up to amazing down the functioning media in buy to make sure that the max temperature is 30ºC-50ºC, reduced than the boiling level. For the closed circulated system of doing work media, the liquid storage unit and cooler should be equipped, and the fuel-liquid separator have to be put in at outlet. The mechanical seal need to 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 45#steel or 40Cr, other components are produced of forged Iron or brass

(2) For the anti-corrosion pump,the parts that the fuel handed, should be created of stainless steel 304 and 306, or other substance appropriate for the respectively corrosive gas, or the areas need to be set with anti-corrosion coating.

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

If the pump is used for vacuuming whilst transferring fuel, the strain of pump outlet exceeds the CZPT environment stress.

When the outlet strain exceeds .15MPa, the unique double-phases liquid ring compressor should be picked and not the vacuum pump refitted. Tthe power of the geared up motor ought to be increased obviously. And the specific gasoline-liquid separator and vehicle-drain device should be equipped too.

When the outlet force is underneath .15MPa, it can use the vacuum pump refitted as compressor. The electricity of the geared up motor must be elevated properly.

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.
