Pumping speed and throughput - Pfeiffer Vacuum

Determination of the pumping speed is described in basic standard ISO 21360-1: 2012. Pumping speed is indicated in m 3 s -1. The units of m³ h -1 , l s -1 and l min -1 are also customary. The throughput q p V = S ⋅ p = d V d t ⋅ p. ( Formula 1-16) denotes the gas throughput in a vacuum pump as a function of inlet pressure.

V throughput - Pfeiffer Vacuum

Throughput is the gas flow rate transported by a vacuum pump. q p V = S ⋅ p = d V d t ⋅ p. Formula 1-16: Throughput of a vacuum pump. Dividing the throughput by the inlet pressure obtains a volume flow rate, the pumping speed of a vacuum pump: S = d V d t. Formula 1-17: Volume flow rate, or pumping speed, of a vacuum pump.

2 Basic calculations - Pfeiffer Vacuum

If the pumping speed of the backing pump is designed precisely so as to attain the turbopump's maximum fore-vacuum compatibility with its gas throughput, then the turbopump rotor will be thermally loaded. A backing pump with a higher pumping speed should be selected to reduce gas friction and the thermal load on the turbopump. The pumping speed ...

2 Basic calculations - Pfeiffer Vacuum

Formula 2-7: Pumping speed of Roots pumping station at high intake pressure. At low pressures, S R from Formula 2-4 is used and we obtain. S = S 0 ⋅ ( 1 − p v K 0 ⋅ p a) Formula 2-8: Pumping speed of Roots pumping station at low intake pressure. From Formula 2-6 , it can be seen that S tends toward S 0 if the compression ratio K 0 is ...

Conductance - Pfeiffer Vacuum

1.2.8 Conductance. Generally speaking, vacuum chambers are connected to a vacuum pump via piping. Flow resistance occurs as a result of external friction between gas molecules and the wall surface and internal friction between the gas molecules themselves (viscosity).
