VacuumFurnaces.com is a Q&A community where vacuum furnace product and service suppliers connect with commercial and captive heat treaters to share their practical skills and know-how and to establish valuable relationships around niche topics of expertise with vacuum furnace end-users in operations, production, training, maintenance, marketing, sales, and engineering.
What leak detection methods are considered to be the most effective for locating small leaks?
Small leaks in a vacuum system are easily detected with a helium mass spectrometer. Helium leak detection is very effective

See lessWhy would a rotary vane pump smoke?
Most likely the pump is operating at a higher pressure than it was design for. Smoke is typically oil vapor carried by the gas (air) leaving the pump.

See lessWhy use partial pressure in a vacuum furnace?
Partial pressure is typically used to raise the pressure in the furnace above the vapor pressure of the material being heated, thus minimizing the out-gassing of certain constituents of the material
