With newly installed units, the mechanical seals of the pumps always have problems, with some experiencing severe leakage. Most of them are PLAN52; what should I do? Do anyone have any suggestions? An accident almost happened; what should be done?
Is the new device leaking severely, and are the pipes dirty? Quality issue? Only by making a judgment based on the actual situation oneself
Whether the machine seal selection is suitable for the process medium
If there is a large-scale leakage, is there an issue with the selection of the mechanical seal? Contact the manufacturer to resolve it, as it’s a new installation
According to the owner’s description, the Plan52 scenario involves a leak on the medium side; however, the leak should occur inside the storage tank and then flow into the drainage system, so it will not pose any risk to safety! Most of the leaks are likely related to quality, as the system should have been washed with water earlier and was relatively clean.
Find the cause of the leak, and then find a solution.
What medium? If the medium is too dirty, switch to the external flushing P32 method
A new unit was installed, and there was severe leakage from the mechanical seal. I’m speechless; I’d better look into the operational aspects instead.
I’ll reply uniformly: the medium is olefin. Has anyone ever encountered problems with installation?
Mechanical seals have little to do with installation; it’s not like in the old days, when equipment would arrive at the site and the contractor had to disassemble it for inspection before reassembling it on site. For a question like yours, the recommended approach to solving it is as follows: 1. Check the differences between the actual process conditions and the design conditions (such as temperature, pressure, and flow rate) ； 2. Check whether the installation quality control procedures and installation record documents meet the requirements specified in the manufacturer’s documentation. Upon examination from the above aspects, it is relatively easy to identify some suspicious points. The fastest way is to work together with the supplier to conduct the inspection (they are likely to check the above two items as well).
