Problems solved by technology
[0005] The problems in the existing design are: 1. The water outlet pipe is on the upper part of the diesel engine, and it is only supported and fixed by the water outlet branch pipe. It is a cantilever beam and is affected by the vibration of the diesel engine during operation. The fastening bolts of the blue are subject to great alternating loads, which are prone to breakage and cause water leakage.
2. The water outlet main pipe is connected by multi-section pipelines, and there are many connection points. Because the compression flange bolts are loose and the tapered pads are not compressed, the pipeline leaks;
3. In appearance, the number of pipelines on the upper part of the diesel engine is large and messy

Embodiment Construction
[0017] Such as Figure 4 It is a structural schematic diagram of the present invention, a new V-type diesel engine cooling water outlet pipeline structure, including a cylinder 1, a surge tank 2, a connecting hose 5, and an intercooler pipe joint 6. The surge tank 2 is installed On the body of the diesel engine, the upper part of the surge tank 2 is provided with an intercooler socket 6, and two drainage cavities 3 are cast inside the intercooler socket 6, and the water chambers 3 are gathered at the end of the intercooler socket 6, and are connected through To the cooling single section of the diesel locomotive; the two drainage chambers 3 have a water inlet at the position of each cylinder 1, and are connected to the water outlet of the cylinder 1 through a connecting hose 5, which can make up for the gap between the two ends entering and leaving the water reed. Coordinate position deviation.
[0018] The connecting hose 5 is made of metal material, which can avoid the resi...

The invention relates to the technical field of a diesel engine cooling system, in particular to a novel cooling water outlet pipeline structure for a V-shaped diesel engine. The novel cooling water outlet pipeline structure comprises air cylinders, pressure-stabilizing boxes, connecting hoses and an inter-cooling device socket. The pressure-stabilizing boxes are mounted on an engine body of a diesel engine, the inter-cooling device socket is arranged at the tops of the pressure-stabilizing boxes, two rows of water chambers are cast inside the inter-cooled device socket, and the water chambers joints at the end of the inter-cooling device socket to lead to a single cooling link of a diesel locomotive. One water inlet of two rows of the water chambers is reserved in the position of each of the air cylinders, and is connected with a water outlet of the air cylinder through one connecting hose. By the arrangement, the problems that a main water outlet pipeline is hung in the air and crack leakage caused by vibration effect easily appears on a branch water outlet pipeline are effectively solved; and the number of external pipelines of the diesel engine is greatly reduced, so that the diesel engine is more tidy and attractive in appearance.
Description
technical field [0001] The invention relates to the technical field of diesel engine cooling systems, in particular to a novel V-type diesel engine cooling water outlet pipeline structure. Background technique [0002] The original V-type diesel engine outlet pipeline is attached figure 1 After the cooling water of the diesel engine cools the cylinder liner and the gas cover, it enters the water outlet branch pipe 11 from the water outlet of each cylinder head, and then collects through the water outlet main pipe, and is output to the cooling single section of the locomotive for cooling. [0003] Restricted by the space structure, there is no position for the outlet main pipe of the diesel engine to be fixed with the body of the diesel engine. The water outlet main pipe is supported and fixed by the water outlet pipes of each water outlet tank. [0004] For the structure of the outlet branch pipe, see figure 2 Each outlet branch pipe 11 and a short section of the outlet ...
