Weifang Huakun diesel engine factory 2636566799 Lin Jingli 13864600749 QQ main Weifang Diesel, diesel generating units and Weichai parts of diesel engine overload for a long time so that the crankshaft long in a state of fatigue, after starting the diesel engine or did not make diesel engine over operation, immediately add lard door high-speed operation, easy to produce fault. Because the original crankshaft in a quiescent state, because of the weight function of the crankshaft and piston and connecting rod assembly, Weifang 4105 diesel engine body parts so that the crankshaft is tightly pressed on a bearing, bearing Central Plains containing lubricating oil is mostly from the crankshaft and bearing clearance squeezed out. When the crankshaft is in high-speed operation, because lubricating oil less, can not form a film, between crankshaft and bearing can not produce liquid friction, can only be in the semi - dry or dry friction state, resulting in bearing in high temperature melting, namely "burning tile", form a "tile holding crankshaft phenomenon.
