Integral casting integrated diesel engine body

Abstract

The invention discloses an integral casting integrated diesel engine body which comprises an engine body and a gear supporting seat, one end of the engine body and one side of the gear supporting seat are fixedly installed, a main engine oil channel is formed in one side of the engine body in a penetrating mode, and main water channels are symmetrically formed in the two ends of one side of the engine body in a penetrating mode. The engine body of the integral casting integrated casting structure is adopted, the main engine oil channel and the main water channel penetrate through the whole engine body, the integration degree of the diesel engine is improved, the hidden danger of weld joint cracking of the cast-weld engine body is solved, the failure rate of the whole engine is reduced, the embedded hidden pipe type arrangement is adopted, pipeline design of a diesel cooling water system and an engine oil system is reduced, and the design cost is reduced; during box closing, the main engine oil channel and the main water channel adopt plug-in core supporting embedded pipes, high-temperature softening and impact of high-temperature molten iron on the embedded pipes are avoided, alcohol-based paint is sprayed on the inner walls of the embedded pipes, the deformation problem in the pouring process is solved, and the problems that a casting engine body is limited by various factors such as a casting process and a mold, and the pipeline integration degree is not high are solved.

Description

technical field [0001] The invention relates to the technical field of a diesel engine body, in particular to a whole-cast integrated diesel engine body. Background technique [0002] At present, the body of domestic medium-speed and high-power diesel engines basically adopts a cast-welded structure or an integral casting structure. At present, most diesel engines use cast-welded body, some small diesel engines use cast body, the pipeline integration degree is not high, the structure of cast-welded body is complicated, there are problems such as welding stress concentration and welding defects, and weld cracking often occurs in the application process , which seriously affects the stable operation of the diesel engine, and the pipelines cannot be integrated inside the body. Although the body of the integral casting structure has solved the welding defects, due to various factors such as casting technology and molds, some pipelines still cannot be directly cast in Inside the...

Problems solved by technology

[0006] The purpose of the present invention is to provide a whole-cast integrated diesel engine body to solve the problems of complex structure of the existing cast-welded body proposed by the above-mentioned background technology, welding stress concentration, welding defects, etc., and weld cracking often occurs in the application process , which seriously affects the stable operation of the diesel engine, and the pipeline cannot be integrated inside the body. At the same time, part of the pipelines of the body of the existing integral casting structure still cannot be directly cast inside the body, and it also affects the appearance of the diesel engine. The main engine oil channel and the main water channel run through the whole body, which improves the integration of the diesel engine itself, solves the hidden danger of weld cracking of the cast-welded body, and reduces the failure rate of the whole machine. It adopts the buried hidden pipe layout , reduce the pipeline design of the diesel cooling water system and the engine oil system, and reduce the design cost. When the main engine oil channel and the main water channel are combined, the embedded pipe is supported by a plug-in core to avoid high-temperature softening and impact of the high-temperature molten iron on the embedded pipe. The inner wall of the embedded pipe is sprayed with alcohol-based paint, which solves the problem of deformation during the pouring process, solves the problem that the casting body is limited by various factors such as casting technology and molds, and the problem of low pipeline integration
