Help post: Measurement of compression of non-cartridge seals
Thread Content
Because I haven’t installed non-containerized seals for about half a year, I am a bit unfamiliar with it and I would like to ask for guidance from the master. Beverly :P
Different structures and different reference points for measurement ( https://wenku.baidu.com/view/d67a0ad549649b6649d74701.html )
The compression amount of a single large spring accounts for 60-70% of the total length of the spring； Multiple small springs can be compressed to 90% of the entire small spring ； The remaining compression of the bellows is 2-3mm.
The working dimensions of standard seal parts from large manufacturers can generally be found online. For non-standard seals from small manufacturers, it is recommended to contact the manufacturer!
Thank you, I would like to find a detailed measurement procedure.
B=L1K-A, it is written in the instruction manual. A is the distance from the sealing surface of the end cover to the O-ring of the stationary ring.
Thank you teacher, thank you teacher! ! !
Please strictly follow the compression dimensions of the dynamic seal part given by the manufacturer to avoid pressure overload or under-pressure.
