It can compose a vacuum system together with Roots Vacuum Pump and atmospheric Jet pump to achieve high vacuum, high efficiency, low power consumption.Â
CURVE
PRINCIPLE DRAWING
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.Â
(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.Â
(3)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.Â
2, Working Media
There are four principles to choose working media(I. E. Ring liquids);Â
(1) Lower saturated steam pressure
(2) Lower viscosity
(3) Stable physical &Â chemical features; No chemical reaction with the pumped gas; No corrosion to the pump; No pollution to the environment.Â
(4) Economy
If the water is selected as the working medium, the best temperature of supply water should be lower than or equal to 15 °C; The highest one should not be higher than 40°C. While the transformer oil or other low viscosity and saturated vapor pressure industrial oils are as the working media, the general supply temperature should not higher than 40°C and the working media temperature inside the pump chamber should not be higher than 60C, when the liquid with lower boiling point is selected as the working media under some special circumstances, the cooling unit must be equipped to cool down the working media in order to ensure that the max temperature is 30ºC-50ºC, lower than the boiling point. For the closed circulated system of working media, the liquid storage unit and cooler must be equipped, and the gas-liquid separator must be installed at outlet. The mechanical seal should be used for dynamic seal of the shaft.Â
3, Choose the dynamic seal of the shaft:Â
Choose the packing seal in general occasion; Choose the mechanical seal when the pump is used in no leak occasion.Â
4, Choose the material of the part that the gas passed:Â
(1) For the non anti-corrosion pump, the shaft is made of 45#steel or 40Cr, other parts are made of cast Iron or brass;Â
(2) For the anti-corrosion pump, the parts that the gas passed, should be made of stainless steel 304 and 306, or other material suitable for the respectively corrosive gas, or the parts should be put with anti-corrosion coating.Â
5, The motor should be selected based on pumping pressure.Â
If the pump is used for vacuuming while transferring gas, the pressure of pump outlet exceeds the standard atmosphere pressure.Â
When the outlet pressure exceeds 0.15MPa, the special double-stages liquid ring compressor should be chosen and not the vacuum pump refitted. Tthe power of the equipped motor should be increased obviously. And the special gas-liquid separator and auto-drain unit should be equipped too.Â
When the outlet pressure is below 0.15MPa, it can use the vacuum pump refitted as compressor. The power of the equipped motor should be increased properly.Â
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.Â
The closed circulation system should be used if the working liquid in the outlet must be circulated.Â

CURVE
PRINCIPLE DRAWING
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.Â
(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.Â
(3)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.Â
2, Working Media
There are four principles to choose working media(I. E. Ring liquids);Â
(1) Lower saturated steam pressure
(2) Lower viscosity
(3) Stable physical &Â chemical features; No chemical reaction with the pumped gas; No corrosion to the pump; No pollution to the environment.Â
(4) Economy
If the water is selected as the working medium, the best temperature of supply water should be lower than or equal to 15 °C; The highest one should not be higher than 40°C. While the transformer oil or other low viscosity and saturated vapor pressure industrial oils are as the working media, the general supply temperature should not higher than 40°C and the working media temperature inside the pump chamber should not be higher than 60C, when the liquid with lower boiling point is selected as the working media under some special circumstances, the cooling unit must be equipped to cool down the working media in order to ensure that the max temperature is 30ºC-50ºC, lower than the boiling point. For the closed circulated system of working media, the liquid storage unit and cooler must be equipped, and the gas-liquid separator must be installed at outlet. The mechanical seal should be used for dynamic seal of the shaft.Â
3, Choose the dynamic seal of the shaft:Â
Choose the packing seal in general occasion; Choose the mechanical seal when the pump is used in no leak occasion.Â
4, Choose the material of the part that the gas passed:Â
(1) For the non anti-corrosion pump, the shaft is made of 45#steel or 40Cr, other parts are made of cast Iron or brass;Â
(2) For the anti-corrosion pump, the parts that the gas passed, should be made of stainless steel 304 and 306, or other material suitable for the respectively corrosive gas, or the parts should be put with anti-corrosion coating.Â
5, The motor should be selected based on pumping pressure.Â
If the pump is used for vacuuming while transferring gas, the pressure of pump outlet exceeds the standard atmosphere pressure.Â
When the outlet pressure exceeds 0.15MPa, the special double-stages liquid ring compressor should be chosen and not the vacuum pump refitted. Tthe power of the equipped motor should be increased obviously. And the special gas-liquid separator and auto-drain unit should be equipped too.Â
When the outlet pressure is below 0.15MPa, it can use the vacuum pump refitted as compressor. The power of the equipped motor should be increased properly.Â
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.Â
The closed circulation system should be used if the working liquid in the outlet must be circulated.Â
