There is a brazing vacuum furnace that we are currently using. We are experiencing various problems with it. We think that it is probably due to diffusion pump.
All gaskets were renewed, difussion oil was replaced with new one.
Control tests were performed with a helium detector.
Internal water cooling leak test done.
Air and Helium Tests were performed on water places.
Although we did all these, when we opened the diffusion valve, it did not work actively.
And there is a little oil on the side of the oven, what is the reason?
Our pumps are less than 1 year old and new.
There are 2 pieces of (150 capacity) 1200 Roots BOOSTER pumps.
This is an urgent issue thats why we would like your contribution and assistance regarding solving the problem as soon as possible.
