Performance Evaluation of Vacuum System: Pump-down Time

Performance Evaluation of Vacuum System: Pump-down Time

Vacuum pump finds application in many number of indus-tries as a vital part of the system. But very few things are known by the engineers regarding vacuum pump and vacuum system performance Vacuum is defined as the space devoid of mater. For general sense it is considered as pressure below atmospheric pressure.

Pumps can be an overpressure hazard to downstream equipment. All positive-displacement pumps should be reviewed as a potential source of overpressure. Normally, the relief device on a pump discharges to the inlet side of the pump — either to the pump suction pipe or to the suction vessel. Routing to the suction vessel is recommended to

The pumping speed against pressure graph for a vacuum booster pump is not a smooth curve. The graph varies from manufacturer to manufacturer even though the pump design is based on the original Roots design. The pump speed curve is similar to a bell-shaped curve and rises to a peak from startup and then drops off as the pressure drops. (Fig. 3)
