Save time and money with regular maintenance

For any production facility, malfunctions in a plant are inconvenient. To get back to normal as soon as possible, it is essential to identify the reason for the malfunction. Mostly, they result from leaks, occurring frequently in the thermocouples feedthroughs, grommets, in valves or diaphragms.

To determine the location of a leak, a leak test has to be performed. Thereby, the plant in a first step evacuates down to 0,10 mbar. When 0,10 mbar are reached, the pressure control valve automatically closes, and the pressure rise will be measured (expressed in mbar*l/sec). A meaningful leak test should run for at least 2 hours. However, a poor leak rate not necessarily indicates a leak. Contamination, lubricants on the batch, moisture in the system (e.g. resulting from excessive oxidation), etc. may also be reasons. These contaminants can evaporate gases into the vacuum, causing the pressure in the system to rise. A cleaning process often works wonders. Power failures on the other hand are not necessarily frequent sources of malfunctions. In case of a blackout, the plant stops immediately and once the power returns, the plant resumes the process where it was cut off. Summing up, regular maintenance on your plant can save you time, money and nerves. It reduces malfunctions to a minimum and may completely prevent plant downtimes.
