How do I make a recommendation report?

The major problem that Trelleborg Sealing is facing is contamination. In most rotary systems, having a seal close to a ball bearing or a different rotary bearing is common. The debris in the system often moves to the bearing leading to more debris to come off the bearing and ruining the seal. Replacing the system fluid does not usually solve this issue since the bearing is a deterrent to complete flushing of the contaminant, which tends to settle close to the seal.

possible solutions:

In order to minimize the possibility of seal failure because of contamination, several recommendations and actions can be made. One is ensuring that all system units are spotless before assembly. They should pay close attention to small metal debris from the machining procedure. The second action is performing frequent checks on the oil in the system to dictate the level of contamination. In case the levels are high, conduct thorough flushing of the system. Lastly, anytime a bearing is replaced in a rotary pump, the seals should also be replaced. It might have been exposed to contaminants and might be susceptible to failure.
