Composition Of The Vacuum System

There are a wide variety of vacuum device, whatever vacuum device, there is always a pumping system that removes the gas from the vessel to obtain the required vacuum conditions in this vacuum vessel. For example: a vacuum processing vessel, which is connected to a vacuum pump by pipes and valves. When the vacuum pump pumps the vessel, the vessel has a vacuum measuring device, which constitutes the simplest vacuum pumping system. (Figure A).composition-of-the-vacuum-system

The simplest vacuum system (Figure A) can only achieve a vacuum in the low vacuum range in the vessel. When it is necessary to obtain a vacuum in the high vacuum range, it is usually connected a high vacuum pump in this vacuum system shown (Figure A). When a high vacuum pump is connected, the valves is usually added to the inlet port and outlet port of the high vacuum pump so that the high vacuum pump can maintain the vacuum alone.types-and-characteristics-of-vacuum-pumps

 If the high vacuum pump is diffusion pump, in order to prevent a large amount of oil vapor from flowing back into the pumping vessel, the trap is usually added to the inlet of the oil diffusion pump – clod trip (Figure B). According to the requirements, it is also possible to add a dust remover, a vacuum relay gauge head, a vacuum soft connection pipe, a vacuum pump inlet bleed valve, etc. on the pipeline, thus forming a relatively complete high vacuum system.is-the-motor-add-a-inverter-could-be-a-vf-motor
