In tritium-related facilities, a large amount of tritium-contaminated pump oil is produced by vacuum pumps, 1 mainly through the tritium–hydrogen (T–H) isotope exchange reaction. 2 The main components of vacuum pump oil are hydrocarbons, such as alkanes, cycloalkanes, and aromatic compounds, 1 plus small amounts of water. When tritium .

Gas Ballasting of Mechanical Oil Sealed Rotary Vacuum Pumps

Jun 15, 2013 · Cleaning Oil Contaminated with Water. If the oil is contaminated with water droplets, gas ballasting the pump will clean up the oil. This may take an hour or two, or several hours depending on the amount of contamination. When the gas ballast valve is open the additional air going through the vacuum pump will create more oil mist at the exhaust.

Note 83: Vacuum Pump Exhaust Filters - Oil Mist Eliminators

The gas ballast valve is used to allow a stream of air to enter the vacuum pump and flush or purge the vacuum pump oil. The vacuum pump exhaust flow rate will exceed 2000 ml/min in this operation. When using the gas ballast valve, any volatile organics or water can be quickly purged from the vacuum pump oil.

Refirs Chapter 28 Flashcards | Quizlet

The vacuum pump oil is contaminated with water. What can be done to speed up evacuation? Drain any standing water in system, use short large diameter hoses, evacuate from both sides of the system, and heat the system being evacuated. How long does it take to pull a deep vacuum?

Understanding Vacuum Pump Lubricants | Ultrachem Inc.

The chosen lubricant must fill all of these roles effectively and efficiently to promote healthy and long equipment life. Vacuum pump applications are somewhat unique due to the relationship between the oil's volatility and vapor pressure. An oil that is more volatile is more likely to turn from a liquid to a vapor as temperatures increase.

Gas Ballasting of Vacuum Pumps (Part 2) | 2017-01-10 .

Jan 10, 2017 · Gas ballast is also used to decontaminate pump oil that has already been contaminated with condensed vapor, which can take several hours for severely contaminated pump oil. To prevent contamination during normal operation, pump manufacturers recommend running the pump with the inlet valve closed and the gas ballast on for 20-30 minutes after .
