Water Ring Vacuum Freeze Drying Pump

Water Ring Vacuum Freeze Drying Pump


2SK series two-phase liquid ring vacuum pumps can perform nicely like two sets of SK sequence h2o ring vacuum pump. Thanks to SK sequence vacuum pumps only get to the greatest vacuum of-700mmHg, to satisfy the large vacuum and the huge pumping velocity beneath high vacuum, China produced the 2SK series drinking water ring vacuum pump in 80s in the twentieth century. 


1. In comparison with SK drinking water vacuum pump ,It gets high vacuum and pumping speed and many others..

2. Straightforward composition and simple upkeep.

3. The primarily functioning medium is h2o and reduced upkeep expenses.

4.The pump is extensively use in numerous areas and suction h2o vapor,flammable, explosive and a variety of gases have a tiny quantity of dust and liquid.

five. The pump can operates in the severe problem


one. Series SK,2SK H2o Ring Vacuum Pumps can be used to exhaust normal gases as effectively as condensable gases(this sort of as h2o vapor). Due to the fact they have the characteristics of isothermal compression, they can exhaust flammable and explosive gases. When the pump manufactured up of anti-corrosion substance is selected, it can be utilized for exhausting corrosive gases way too.


two. Sequence 2YK Liquid Ring Vacuum Pumps have the characteristics of larger vacuum and much better applicability. The various types of gases can be pumped with the selected appropriate operating media. Therefore, they can be applied in wider assortment.


3. The pumps run smoothly with lower noise and usage. The strength-conserving is 30 percent evaluating 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
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~one.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
(3) 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 picked as the doing work medium, the greatest temperature of offer water ought to be lower than or equal to 15 °C the optimum one particular ought to not be increased than 40°C. Even though the transformer oil or other low viscosity and saturated vapor pressure industrial oils are as the doing work media, the standard provide temperature need to not increased than 40°C and the working media temperature inside the pump chamber ought to not be larger than 60C, when the liquid with decrease boiling position is selected as the operating media under some specific circumstances, the cooling device need to be geared up to great down the operating media in purchase to make certain that the max temperature is 30ºC-50ºC, reduced than the boiling point. For the closed circulated technique of working media, the liquid storage unit and cooler must be equipped, and the gasoline-liquid separator need to be set up 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.

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

(1) For the non anti-corrosion pump, the shaft is created of 45#steel or 40Cr, other areas are created of forged Iron or brass

(two) For the anti-corrosion pump,the areas that the gasoline passed, must be made of stainless steel 304 and 306, or other content appropriate for the respectively corrosive gasoline, or the elements ought to be put with anti-corrosion coating.

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

If the pump is employed for vacuuming even though transferring gas, the strain of pump outlet exceeds the CZPT atmosphere stress.

When the outlet pressure exceeds .15MPa, the unique double-phases liquid ring compressor ought to be decided on and not the vacuum pump refitted. Tthe electricity of the equipped motor should be elevated certainly. And the particular gas-liquid separator and automobile-drain device ought to be outfitted as well.

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