I'm very new and inexperienced to the whole industry and physics behind the processes, but very interested and willing to learn as much as possible.
I would greatly appreciate any answer to my problem with vacuum pressure failing when my radiant heater is switched on. I have just fully serviced both diffusion and backing pump, cleaning and replacing oils. The belljar has also been cleaned along with items contained.
The pressure is good until the heater is on. Is this normal considering the exposure to atmosphere and moisture when cleaned?. Is the problem likely to improve through use? Or is it possible the heat could be exposing a leak?.
The diffusion and backing pump appear to be working well.
The plant is an old Edwards. Guessing built in the 70's-80's. Mainly used for anti-reflection coatings and alumnising in a optical workshop.
My ignorance and lack of knowledge is probably amusing but I'm very lost and could use any help I can get.
