Liquid Ring Vacuum Pump Power Calculation Formula

Some equations are presented below for the benefit of the readers.

Liquid ring vacuum pump power calculation formula.

Concerning the power of liquid ring pump due to the absorption and the removal of the heat by the operating liquid the gas compression process in the liquid ring pump is generally regarded as isothermal one so the formula for the isothermal compression power of the ideal gas is commonly used to calculate the effective power of the liquid ring pump 12 13. You might get a doubt that how the formula for pump capacity is derived but there is nothing but just a unit conversion by incorporating the required end vacuum i e ultimate pressure. Can you share everest screw vacuum pupm calculation link. If the discharge pressure is increased then more energy or brake horsepower is required to operate at the increased compression range.

Water ring vacuum pumps are often used in the vacuum system of large paper machines which refer to water ring vacuum pumps. Liquid ring pump 20 30 torr 2 5 torr. Liquid ring nash pump. Bkw 13 5 sf 1 088 where.

Liquid ring vacuum pumps are all rated in acfm the actual capacity at the different vacuum levels as shown on the individual pump performance curves. Today s blog entry deals with quick but reliable estimate of the power consumption of vacuum pumps used in the chemical process industry. Bkw 21 4 sf 0 924 rotary piston pump. Water ring vacuum pump has less maintenance workload less power consumption than the former and large single machine capability but it needs working fluid and the system is relatively complex.
