Carter high quality replacement parts, repair kits, carter construction machinery spare parts, overhaul
Carter generator engine cylinder is refers to the generator set accessories carter cylinder wall in the range of the movement of the piston ring appears obvious longitudinal mechanical scratch and scratch, serious when the event as a sex wear and tear, caused by generator set accessories carter started difficult or shut down on its own fault, cylinder is one of the generator set accessories carter to a major accident.
Carter generator set accessories cylinder is difficult to form between the cylinder wall and piston ring, piston oil film, thus cause poor lubrication, appear even the phenomenon of dry friction.
There are many reasons that cause this phenomenon.
Generator set accessories carter piston ring gap is too small, if the piston ring opening gap is too small, or back, side clearance clearance engine piston ring heat expansion stuck at work, and a tight or pressure of the cylinder wall broken piston ring, and it is easy to pull in carter generator set accessories cylinder wall groove.
Generator set accessories carter piston pin appear will also pull cylinder.
Due to the generator set accessories carter piston pin card spring or fall off, broken, the movement of the piston pin came out, it is easy to strain the inner wall of the cylinder, cylinder channeling caused by air to the crankcase.
Generator set accessories carter piston cylinder liner clearance is too small or too large, if carter generator set accessories of piston material, manufacturing size error is too large, or assembling piston pin after carter generator parts deformation piston, piston and cylinder of the fit clearance is too small, stuck after piston thermal expansion, and strain of cylinder wall.
Generator set accessories carter piston ring serious carbon deposit also causes piston ring binder or killed in the ring grooves, can form a kind of hard abrasive formation at the same time, the cylinder walls into longitudinal grooves.
Carter generator set accessories cylinder piston is serious, because of the connecting rod bending and twist deformation, connecting rod journal, main journal, parallelism and axiality deviation of piston pin is too large, cause carter generator was noticeably cylinder piston, will accelerate the wear of piston ring, piston and cylinder wall, destroy the formation of oil film.
