I would like to ask the experts about the rinsing procedures for PLAN32, as well as PLAN52/PLAN54
Thread Content
I’ve looked at some information on machine seal flushing solutions, but I still have some doubts. I’d like to ask the experts: what are the specific differences between PLAN32, PLAN52, and PLAN54? Thank you, happy New Year:lol
Solution 32 involves introducing an external cleaning fluid to flush the sealed end face, which helps prevent particles, vaporization, high temperatures, and corrosion; it is the best solution for dealing with single-end face issues. However, it requires an appropriate cleaning fluid on site, and its consumption is high； Second, it will dilute or contaminate the material being pumped. Therefore, this solution is generally avoided as much as possible; it is even less considered for cooling purposes. Scheme 52 involves a pressure-free buffer fluid circulation that passes through the sealant tank; the flow is driven by a pump mechanism located within the dual-seal system. It is suitable for non-polymerizing fluids whose saturated vapor pressure is higher than that of the sealant, and it does not allow leakage to the atmosphere. It is not suitable for heavy fluids, dirty fluids, or fluids that tend to polymerize (in such cases, Scheme 53 should be considered). When used with alkalis, amines, or fluids that tend to crystallize, clean water is used as the buffer fluid to dissolve any particles that may leak out. Scheme 54 features an external oil station through which the isolation fluid is circulated; this approach results in higher costs. It is suitable for methane, ammonia, propane, and other hydrocarbons with high saturated vapor pressures, and it offers high reliability. 53
32: Refers to internal flushing, entering the material side； 52&53: Encrypt and seal ； 54: Refers to an external forced circulation system ；
Thank you :) Happy New Year:lol Is there a gas station next to 54 that uses oil for circulation?:o
What is the difference between an airtight sealing system and a forced circulation system: dizzy:
It mainly depends on the usage amount; if the quantity is small, a storage tank is suitable, while the 54 system can be used for bulk quantities.
It’s explained in great detail; thanks for sharing
