Vacuum Pumps Common Problems and Troubleshooting
Vacuum pumps and systems are one of the widely used equipment in process plants. It is very
important to correctly size and select the vacuum pump as it is to lay down the right specifications.
Understanding the fundamentals of vacuum as well as the system and its integration would enable the
operators to deal with the day to day problems, which are inevitable.
This article highlights various trouble shooting guidelines for some of the most commonly used
vacuum machines like liquid ring vacuum pumps, rotary piston vacuum pumps, dry vacuum pump,
rotary vane vacuum pump and vacuum blower.
Several factors govern and influence the performance of a vacuum system. It is important to
periodically inspect the vacuum system and all its accessories including the upstream and down-
stream piping and equipment for leakages as it plays a major role in the performance of a vacuum
system.
Some of the common problems faced in vacuum systems could be on account of the following major
factors:
• Process conditions and variations
• Variation in utility specs
• Equipment malfunction
The suction load, temperature, leakage rate and other process parameters including the composition
of suction gas are crucial for proper functioning of a vacuum system. These parameters can be
estimated as per the standards of the Heat Exchange Institute and other standards. These standards
can also be applied for testing the performance of the vacuum system. Once the external step is to
evaluate and solve the problems associated with the vacuum unit.
Some of the most commonly observed problems in different kinds of vacuum pumps along with
suitable trouble-shooting guidelines are discussed in this article.
