Pay attention to the statistical issues related to the dynamic sealing points of devices
Thread Content
For the statistics of dynamic sealing points, let’s first look at the definition: a seal between two coupled components that are in continuous motion is considered a dynamic sealing point. In other words, it cannot be counted for parts such as valve stems in valves. Moreover, the machine seal oil seals for pumps are not that numerous, and the leakage rate at the dynamic seal points of the equipment should be no more than 0.2 per thousand; any leakage beyond this level will constitute a violation of the standards. I ask, how do you count the sealing points on the device, everyone?
We have taken counts at every valve stem of ours
Yes, I also want to do statistics; otherwise, how can we ensure 0.2 percent? But this conflicts with the definition of sealing, as dynamic sealing emphasizes continuous motion
