Abnormal noise occurs in the reciprocating compressor when it is running under no load
Thread Content
Today, when switching the reciprocating compressor and running the standby unit under no-load conditions, a buzzing sound was heard, similar to the sound of pistons rubbing against the cylinder barrel; however, this sound disappeared once the unit was under load.
Does anyone know what the reason is?
The sound of the packing rubbing against the piston rod or the intermediate packing rubbing against the piston rod
It should be; why is there no sound after loading?
The pressure imbalance was mild, likely due to excessive clearance in the cylinder rings; excessive vibration of the piston rod caused friction, but once the pressure returned to normal, everything improved
There are 10 reciprocating compressors in the workshop; this is the first time I’ve encountered such a situation
Keep this in mind; you’ll know when doing a major repair by taking it apart for inspection~~~ I think it’s the friction between the piston rings and the cylinder surface~~~ Hehe:lol
