What causes the piston rod of a reciprocating compressor to be oily? There are also reasons that cause instability in the power oil pressure of the turbine
What causes the piston rod of a reciprocating compressor to be oily? Excessive wear of the seal requires replacement； An excessive bearing clearance is the cause of unstable power oil pressure in the turbine.
The piston rod of a reciprocating compressor is lubricated – this is a bit vague; does the lubrication come from the crankcase or from within the cylinder? 1. Oil leakage from the crankcase is usually caused by worn oil scavenge rings, which need to be replaced. 2. The cylinder is leaking oil; it is likely that the packing seal is worn or damaged and needs to be replaced. I don’t understand turbines!
The piston rod is oily due to worn oil scrapper rings or worn piston rod
Oil leakage in piston compressors is caused by worn oil scrapper rings and packing seals, while in steam turbines it is due to increased bearing clearances
