2019-5-21 · Before the experiments, an orifice type manuel flow meter (AM 3000) was installed on the inlet line of the vacuum pump to make flow rate measurements, which had a capacity of 3,000 l min-1. Vacuum changes of the pump were monitored using a digital vacuum meter (DVPM-01) with 0.1 kPa precision, mounted on the flow meter via a hose.
2020-8-19 · Various strategies are used to overcome this, including relying on the vacuum pump to simply remove the invading molecules, and using materials with better permeation constants. The other relevance of diffusion in vacuum systems involves the diffusion pump (Fig. 12), which is commonly used to achieve a high vacuum.
