Vacuum Pump Throughput Calculation at Lewis Pilcher blog

Vacuum Pump Throughput Calculation. Describe the terms “throughput”, “pumping speed” and “conductance” and explain. The pump speed delivered to the vessel is calculated, and finally, the time to pump from the upper pressure limit of the interval to the lower pressure limit of the interval is computed. Verify vacuum requirements are met. The pump down time calculation from the start pressure to the target pressure of the configured vacuum system. The pumping speed is the “transportation capacity” which the pump makes available within a specific unit of time, measured in m 3 /h or l/s. The pump throughput is the quantity of gas moved by the pump over a unit of time, expressed in mbar ≠ l/s; Throughput is the gas flow rate transported by a vacuum pump. Calculate the gas load of the bulk gas present in a vacuum chamber before initiating a system pumpdown. The overall concept that encompasses all vacuum systems and processes is easiest to understand when written as the equation q (gas load) = s.
