Drei Hauptverunreinigungsquellen in Schmiersystemen

Three main sources of contamination in lubrication systems - Spectro Scientific

Contamination control can be divided into two main parts: ingress prevention and disposal. Since none of the methods alone is sufficient, both should be considered as a good pollution control strategy.
To prevent contaminants from entering, it is very important to understand the possible sources of contamination and their penetration into the system. External contaminants can be introduced through any penetration point, such as a breather, seal, port, hatch or other inlet.
Although most people think that pollutants come only from an external source, they can also come from within. In addition, you should not discount the probability of human interaction with the system as a source of pollution. Thus, we are dealing with three sources of oil pollution:
- pollutants entering the system,
- pollutants formed inside it,
- and pollution created by human interaction.
Contaminants can enter the system due to poor seal design, worn seal materials, and operating or environmental conditions. External impurities can penetrate through damaged shaft seal points. For hydraulic components, windshield wiper seals and rods will inevitably be the source of this problem, since contaminants damage the seal materials during prolonged use. Therefore, it is necessary to control how the amount of contaminants in the oil in order to replace these seals in time, thus preventing further deterioration of the oil condition and destruction of the mechanism. For this purpose, as a rule, particle counters are used, such as the particle counters of the LNF series, which are included in the Minilab 53 and Minilab 153 mini-laboratories. They allow you to track the accumulation of polluting particles, classify them and control their size.
