Web2 days ago · The importance of inert gas flow (e.g., argon, nitrogen, or helium) is evident in laser powder bed fusion (LPBF) [1].The recent results have revealed its significant influences on LPBF processes and consistent quality attributes, e.g., surface roughness, microstructure, porosity, and lack of fusion of the printed components [2], [3], [4].The gas … WebThis is also referred to as pV flow or gas throughput. Throughput is the gas flow rate transported by a vacuum pump. qpV = S ⋅ p = dV dt ⋅ p 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:
