Where is the oil scrapper ring of the compressor? I only know that there is an oil scrapper ring at the point where the crankcase connects to the piston rod. Is there also an oil scrapper ring at the point where the cylinder gasket connects to the piston rod? Seeking advice
I’ve never seen a compressor stuffing box without an oil-scraping ring
It’s also present on the cylinder side, inside the packing
An oil scraper ring is installed on the side close to the crankcase to prevent oil from the crankcase from entering the system, while a pressure main packing is placed on the side close to the cylinders; an intermediate isolation packing is usually installed between the two
Between the crosshead and the stuffing box, there is an oil scraper, which contains an oil scraping ring inside. It is used to scrape off the oil that is carried onto the piston rod due to reciprocating motion, preventing oil from entering the cylinder. Danger is imminent.
Scraper rings are present at the compressor middle body and the intermediate sleeve to prevent the crosshead lubricating oil from being carried away by the reciprocating motion of the piston rod
