Analysis of Common Faults of Piston Ring in Diesel Engine
Diesel engine piston ring common faults operating gas counterpart contusion broken death oil and other reasons
1 the piston ring ring opening wrong position is not correct and even mouth mouth gap is too large ring strain broken or dead resulting in gas lost caused by the adverse effects of poor breathing.
2 diesel engine work cube piston ring in addition to the expansion of the building there are along the circumference of the crawling trend not only accelerated the ring surface wear but also the corresponding piston ring. Piston ring is the rotation cylinder liner piston roundness cone with the gap is too large reasons connecting rod bending cylinder wall honing irregular road and so on.
3 the piston ring gap the gap is too small ring and cylinder wall friction is too large the cylinder of carbon deposition serious dirty or oil when the assembly is not clean resulting in personal injury.
4 the piston ring clearance is too small after the new ring the first cylinder hit cylinder liner or assembly ring piston ring extension is too easy to break.
5 the side gap is too small do not use a special tool to disassemble spiral ring resulting in elastic effects or carbon deposition in the cylinder serious will cause the piston ring death.
6 the piston ring gap the side of the gap is too large deformation cone up and down direction and lubricating oil dirty oil hole plug easily lead to oil.
7 the piston ring gap is too small open the impact; clearance is too large ring impact; old cylinder a new ring the first air ring and cylinder liner hit these conditions will lead to noise.
