Oil field tool

摘要: The oil field tool motor is particularly suited for use in the well shaft environment wherein temperature within can climb to nearly 400° F. and drop −400° when liquid nitrogen intermittently fed therethrough. incorporates a stator sleeve guide bearings rubber elements thereof, which cause seizure of due swelling against rotating structures therewithin caused by high ambient impregnation nitrogen, are replaced with identically sized configured made material having suitable level lubricity, does not interact chemically or absorb physical characteristics only minimally affected, if at all, temperatures, eliminating under these conditions use.
