Do the packings of reciprocating pumps or reciprocating compressors need to be run-in?
Thread Content
For example, for reciprocating compressor piston rod packing, some literature says that it should be run-in for a certain period of time without load, and then run normally again.； Some say there is no need to run it in, just increase the amount of lubricant. Which one is correct? This post was last edited by superblade on 2009-3-26 09:16 ]
The piston rod packing is a standard accessory. It is generally not a high-risk medium with ultra-high pressure, so there is no need to run it in!
I have used a reciprocating compressor, and the piston rod packing is just like what Haiyou said above. The standard accessories do not need to be run-in, but attention should be paid to the normal supply of cooling water for the packing.
There are generally two types of packing seal structures:: Flat sealing ring and cone sealing ring Flat sealing ring is used in low and medium pressure cylinder packing. Cone sealing ring is used in high pressure cylinder packing. Compressor packing seal is to obtain a self-tightening seal by means of gas pressure difference. Generally, there is no need for running-in.
Those without oil lubrication require running and adjusting, while those with oil lubrication do not need running and adjusting if the gaps are well matched.
need. But they are usually run-in before leaving the factory~
It should be run-in for a certain period of time without load, and then run normally again. Otherwise, the unit needs to be oil-run, no-load test run, load test run, and finally put into normal use before starting work.
