11 Mar 2016 Last time we focused on the principles of operation of oil sealed rotary vane pumps including basic pump design, and pump oil. We now continue that discussion focusing on operational features and the inner workings of these pumps. Single Stage vs Two Stage Pumps. One of the limiting factors of a rotary
14 Jun 2016 If the oil vapor pressure is too high, it will vaporize when exposed to vacuum, and the vapor can contaminate the vacuum chamber (referred to as backstreaming). For this reason, the vapor pressure is one of the factors dictating the ultimate vacuum the pump can achieve. Rotary Pump Oil. The rotary vane
9 Apr 2014 By Howard Tring. Introduction. As stated last month, in Part 1, this article talks only about one and two stage “medium vacuum” oil sealed rotary vane vacuum pumps that can produce a catalog ultimate vacuum of about 1 x 10-2 Torr (0.01 Torr or 10 microns) for a one stage model and about 1 x 10-3 Torr
10 Jan 2017 Let's learn more. What is gas ballast? Gas ballast is the introduction of a non-condensable gas (e.g., air or nitrogen) into a rotary-vane pump, during the compression stage to intentionally impact the efficiency of the pump thereby heating the oil inside and helping to drive out water and other condensed . . .
5 Dec 2016 Gas ballasting is essential for oil-sealed pumps such as rotary-vane (i.e., mechanical) pumps, but it is often poorly understood or neglected as part of the daily maintenance routine on a vacuum furnace. As a matter of good practice, it should be done for about 20-30 minutes each day and is normally
The Leybold D65B Trivac is a durable vacuum pump with a superior vapor handling capability. The Leybold D65 D65B dual stage rotary vane mechanical vacuum pump offers an excellent ultimate pressure of 1x10-4 Torr. These pumps are commonly used for vacuum furnace evacuation, backing turbomolecular pumps,
