Novel monoblock pump box structure

Abstract

The invention provides a novel monoblock pump box structure which comprises a pump box body. The section of the pump box body is of a V-shaped structure, a plurality of monoblock pump mounting holes are formed in the two sides of the V-shaped structure and penetrate through the pump box body, and a machine body mounting hole and a monoblock pump fixing hole are further formed in the end face of the V-shaped structure. The outer side of the V-shaped structure is provided with a diesel oil inlet channel, a diesel oil return channel, an engine oil inlet channel and an engine oil return channel which are integrally formed in the axial direction, and the diesel oil inlet channel, the diesel oil return channel, the engine oil inlet channel and the engine oil return channel are each provided with an oil channel communicated with the monoblock pump mounting holes. According to the pump box structure, the rigidity and the strength of the pump box are improved, meanwhile, the pump box and a machine body are integrally installed in the V-shaped included angle of an engine, and the rigidity and the strength of the whole machine are improved; and meanwhile, the invalid space of the whole machine is reduced, and the compactness of the whole machine is improved.

Description

technical field [0001] The invention belongs to the technical field of engine matching devices, and in particular relates to a novel single-pump pump box structure. Background technique [0002] For a multi-cylinder diesel engine that uses a single pump oil supply system, there are generally two types of single pumps, one is a combined single pump, which looks like a traditional in-line pump, and the other is a split single pump. body pump. Both of these two pumps have disadvantages such as weak pump body strength and complicated structure (need to design special oil pipeline and diesel pipeline). Bring a lot of invalid spaces to the whole machine simultaneously, and the compactness of the whole machine is poor. [0003] If the diesel engine is a V-type engine, the unit pumps are arranged inside the V-shaped angle of the engine. Once the oil leakage occurs in the oil inlet and return pipeline of the unit pump, many peripheral parts need to be removed to troubleshoot, so th...

AI Technical Summary

Problems solved by technology

Both of these two pumps have shortcomings such as weak pump body strength and complex structure (need to design special oil pipeline and diesel pipeline)

At the same time, it brings a lot of invalid space to the whole machine, and the compactness of the whole machine is poor.

[0003] If the diesel engine is a V-type engine, the unit pumps are arranged inside the V-shaped angle of the engine. Once the oil leakage occurs in the oil inlet and return pipeline of the unit pump, many peripheral parts need to be dismantled to troubleshoot, so the maintenance of the whole machine is very poor.
