7H diesel engine cylinder head
Positive constant power production of this 7H cylinder head, supporting 7H engine cylinder block, using the international advanced structural design and unique oil saving technology, with high oil saving rate, light weight, strong power characteristics. After assembly, the product is used for large agricultural tractors with high horsepower and good traction performance. It is suitable for high speed operation in large farms with wide farm tools.
The cylinder head is mounted on top of the cylinder block, sealing the cylinder from the top and forming the combustion chamber. It is often in contact with high temperature and high pressure gas, so it bears great thermal load and mechanical load. The cylinder head of a water-cooled engine is provided with a cooling water jacket, and the cooling water hole on the lower end of the cylinder head is communicated with the cooling water hole of the cylinder block. The circulating water is used to cool the high temperature parts such as the combustion chamber.
The cylinder head is generally made of gray cast iron or alloy cast iron. The thermal conductivity of aluminum alloy is good, which is conducive to improving the compression ratio.
Engine cylinder head is one of the most critical parts of the engine, its high precision requirements, processing technology is complex, processing quality directly affects the overall performance and quality of the engine, therefore, engine cylinder head processing is particularly important, its key parts of the valve seat ring and pipe hole processing is the most important.
