Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of marine medium-speed diesel engine pipelines, and particularly relates to an integrated device for marine medium-speed diesel engine pipelines. Background Art
[0002] Exhaust gas turbochargers are installed on marine medium-speed diesel engines. Currently, the high-efficiency turbochargers applied in the market are lubricated and cooled with lubricating oil.
[0003] The fuel injection pump of a marine medium-speed diesel engine needs to be cooled with lubricating oil. The fuel injection pump has high requirements for the cleanliness of the lubricating oil, and a separate filter needs to be added to filter the lubricating oil here. Generally, a lubricating oil pump and a fresh water pump are installed at the free end of a marine medium-speed diesel engine. To reduce the length of the lubricating oil pipeline and the lubricating oil pressure loss, the lubricating oil inlet of the diesel engine is generally designed at the free end.
[0004] According to the requirements of the layout of the ship's engine room, sometimes it is necessary to arrange the turbocharger of the diesel engine at the free end. At this time, there are both the lubricating oil pipeline of the turbocharger and the lubricating oil pipeline and fuel pipeline of the fuel injection pump at the free end of the diesel engine. With so many pipelines arranged together, due to the different directions of many pipelines, the pipelines at the free end of the diesel engine are relatively messy.
[0005] The messy pipeline structure causes great difficulties in subsequent maintenance, repair, disassembly and troubleshooting. Specifically, the complex pipeline system is connected to various functional components, resulting in time-consuming and laborious troubleshooting, and often misconnecting pipelines during maintenance, leading to oil leakage or even fuel injection defects.
[0006] Therefore, it is obvious that the complex pipeline system not only causes great difficulties in the installation, maintenance, repair and troubleshooting of the diesel engine, but also easily causes mutual extrusion between pipelines, resulting in easy failure of the oil pumping. For example, the deformation of the pipeline caused by the accumulation and extrusion of dense pipelines will affect the oil transmission of the pipeline. Content of the Utility Model
[0007] Based on the above background, the purpose of the utility model is to provide an integrated device for marine medium-speed diesel engine pipelines.
[0008] To achieve the above purpose, the utility model adopts the following technical solutions:
[0009] An integrated device for marine medium-speed diesel engine pipelines includes an integrated joint body installed on the diesel engine;

[0015] A number of interfaces are provided on the first oil passage for connecting to a water pump and a gear box body respectively.

The lubricating oil pipes are connected to the oil inlet positions of the corresponding water pump and gear box body for lubricating mechanical parts inside the water pump and gear box.
[0027] The utility model has the following beneficial effects:
[0028] In the utility model, a joint body is designed. An oil lubrication channel and a fuel channel are designed on the joint body to allow the lubricating oil and fuel to flow into and out of the joint body. Relevant pipelines are connected to each interface on the joint body. At the same time, a fuel filter and a lubricating oil filter are installed on this joint body. The joint body is fixed to the engine body of the diesel engine by 6 bolts. After the lubricating oil enters the joint body and flows through different flow channels, it enters functional components such as the lubricating oil filter, water pump, gear box, supercharger, fuel injection pump, etc., thus solving the defect that in the traditional method, the oil circuit is connected through complex pipelines, which makes it impossible to clarify the pipelines during subsequent maintenance and repair due to the overly complex and messy pipelines, resulting in difficulties in maintenance and repair.
