Treatment method of cylinder head deformation of mine loader engine

Due to the long-term operation of the engine head in high temperature, high pressure, thermal load and alternating load environment and warping deformation, cylinder gasket from the mouth of the bad, resulting in the combustion chamber pressure drop, engine power shortage and radiator add water to the outside Water. The processing method of the engine cylinder head deformation is: because there is no concave shape of the combustion chamber on the cover, there is no need to consider the change of combustion volume (the change value of the combustion chamber volume should not be greater than 4% of the original volume), and the surface milling method is used to process the cylinder head PLANE. , in the cylinder head and the joints of the cylinder body is installed a copper pad (the thickness of the copper cushion is 1.2 times times the thickness of the water crossing groove), instead of the rubber seal on the cylinder gasket, and then the installation of the cylinder gasket, at the same time the first cold tight after the heat tight method of solid cylinder head Bolts. This method is used to repair the engine, no more failure occurred in the punching cylinder gasket.
