Auxiliary system for diesel engine

Abstract

The invention discloses an auxiliary system for a diesel engine, which comprises a lubricating oil filter, a low-temperature cooling water pump, a high-temperature cooling water pump, a main engine oil pump, a lubricating oil cooler, a cooling circulating water temperature controlling device, an intercooler installing box and an auxiliary supporting box body, wherein an external cooling water inlet and an external cooling water outlet are arranged at the upper part of the front surface of the auxiliary supporting box body; the low-temperature cooling water pump, the high-temperature cooling water pump and the cooling circulating water temperature controlling device are integrated at the upper part of the front surface of the auxiliary supporting box body; the main engine oil pump and the lubricating oil cooler are integrated at the lower part of the front surface of the auxiliary supporting box body; the intercooler installing box is integrated on the top surface of the auxiliary supporting box body; a filter connecting outlet is arranged on the lubricating oil filter; and the lubricating oil filter is integrated on the lateral surface of the auxiliary supporting box body through the filter connecting outlet. The invention has higher integration level and less auxiliary pipelines, simplifies the assembly process, is convenient for maintenance, reduces the casting difficulty, and lowers the production efficiency of waste products.

Description

technical field [0001] The invention relates to a diesel engine auxiliary system, which belongs to the technical field of diesel engines. Background technique [0002] At present, the cooling water circulation and engine oil lubrication circulation system in the front support box of the medium-speed in-line diesel engine at home and abroad are separately established, and corresponding supporting oil pumps, water pumps and a large number of external pipelines are required for installation and use to realize the high and low temperature of the diesel engine. Cooling water circulation and oil lubrication system circulation, this structure requires a large number of pipeline connections, complicated assembly, and a low degree of system integration. There are also situations in foreign countries where the diesel engine auxiliary system is integrated into the front support box of the diesel engine. Specifically, the intercooler installation box, bearing box, lubricating oil filter...

Problems solved by technology

[0002] At present, the cooling water circulation and engine oil lubrication circulation system in the front support box of the medium-speed in-line diesel engine at home and abroad are separately established, and corresponding supporting oil pumps, water pumps and a large number of external pipelines are required for installation and use to realize the high and low temperature of the diesel engine. Cooling water circulation and oil lubrication system circulation, this structure requires a large number of pipeline connections, the assembly is complicated, and the system integration degree is not high

There are also situations in foreign countries where the diesel engine auxiliary system is integrated into the front support box of the diesel engine. Specifically, the intercooler installation box, bearing box, lubricating oil filter, oil pump and water pump in the auxiliary system are integrally integrated into the front support box of the diesel engine. However, due to its completely non-pipeline design, it requires a relatively high level of casting technology, which is relatively difficult for Chinese domestic foundry companies. At the same time, the integration is too high, resulting in an increase in the scrap rate. Once a leak is found, the front-end The integrated cabinet is replaced as a whole, which is extremely inconvenient for maintenance and installation
