Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.
[0032] a kind of like figure 1 , 2 The main marine diesel engine front-end system shown includes front-end box 1, fuel filter 6, lubricating oil temperature control box 15, lubricating oil cooler 16, self-cleaning lubricating oil filter 17, high-temperature cooling water pump 20, low-temperature cooling water pump 21, A constant temperature water tank 30 and a double pump 2 that integrates fuel oil and lubricating oil and pressurizes them separately. The double pump 2 is integrated with the high-temperature cooling water pump 20 and the low-temperature cooling water pump 21 at the front lower part of the front end box 1. The constant temperature water tank 30 and the lubricating oil temperature control box 15 are integrated in the front upper part of the front end box 1 sequentially from bottom to top, the lubricating oil cooler 16 is in...

The invention discloses a main pushing diesel engine front end system for a ship. The main pushing diesel engine front end system for the ship comprises a front end box, a fuel filter, a lubricating oil temperature control box, a lubricating oil cooler, a self-purification type lubricating oil filter, a high-temperature cooling water pump, a low-temperature cooling water pump, a constant temperature water box and a double pump, wherein the double pump can user both fuel oil and lubricating oil and can carry out pressurizing respectively. The double pump, the high-temperature cooling water pump and the low-temperature cooling water pump are integrated on the lower portion of the front face of the front end box. The constant temperature water box and the lubricating oil temperature control box are sequentially integrated on the upper portion of the front face of the front end box from bottom to top. The lubricating oil cooler is integrated on the top of the front face of the front end box through a cooler installation base. The self-purification type lubricating oil filter is integrated on the top face of the cooler installation base. The fuel filter is integrated on the lower portion of the side face of the front end box and is communicated with a fuel oil outlet pipeline of the double pump. The processes of supplying the fuel oil and the lubricating oil and cooling the whole main pushing diesel engine for the ship are finished, the integration level is high, the difficulty of casting a box body is reduced, the rejection rate is reduced, and later maintaining and installing are convenient.
Description
technical field [0001] The invention relates to a front-end system of a marine main propulsion diesel engine, in particular to a system capable of adjusting the temperature and pressure of the cooling water and lubricating oil required by the entire diesel engine; it can filter the fuel and lubricating oil required by the entire diesel engine; it can be the main propulsion system. The cooling water pump, lubricating oil pump, and fuel pump of the diesel engine provide power transmission and installation positions; a highly integrated front-end system that can realize the output power of the free end of the diesel engine. Background technique [0002] At present, the marine diesel engines represented by "MAN" in foreign countries adopt modular design, effectively design the cooling, lubrication and other systems as a highly integrated module, thus eliminating the complicated peripheral pipelines of traditional diesel engines and facilitating the operation of diesel engines in ...
