Description
Technical Field
The utility model relates to a marine diesel generator set, in particular to a marine low-resistance loss air inlet pipe.
Background
At present, the power used by a marine diesel generating set is gradually increased, so that the structural size of a diesel engine is continuously increased, the number of corresponding superchargers is increased, and a multi-path air inlet mode is caused. Because of the space limitation of the cabin, it is impossible to add a plurality of air intake pipes and a filter device, and therefore, the air intake pipes need to be combined into one path and then connected with the cabin air intake system. Because the pipeline loss of the air inlet end has great influence on the air inlet vacuum degree of the diesel engine, the air inlet pipelines need to be effectively combined under the conditions of limited space and pipeline loss.
Disclosure of Invention
The utility model aims to provide a marine low-resistance-loss air inlet Y-shaped pipe under the condition of limited space and structure of an engine room, and the air inlet pipeline is combined within the limited structural space and pipeline loss requirements, so that the use requirements of modern ships are met.
In order to achieve the purpose, the technical scheme of the utility model is as follows: the utility model provides a marine low resistance loss Y type pipe of admitting air, divides pipe, main inlet manifold, Y type pipe body including admitting air, Y type pipe body upper portion is equipped with main inlet manifold, and the lower part is equipped with two and admits air and divides the pipe, and two admit air and divide the pipe to merge into one kind with two way gas intakes through Y type pipe body to link to each other with main inlet manifold, two the pipe is connected with the booster air inlet of diesel engine to main inlet manifold through upper portion is connected with cabin air intake system, realizes the function that main inlet manifold merges.
Furthermore, the air inlet branch pipe is in arc transition connection with the Y-shaped pipe body.
Further, the air inlet main pipe is in circular arc transition connection with the Y-shaped pipe body.
Furthermore, the two air inlet branch pipes are connected with an air inlet of a supercharger of the diesel engine in a sealing mode through flanges.
Further, the air inlet main pipe is connected with the cabin air inlet system in a sealing mode through a flange.
The beneficial effects of the utility model are:
the marine low-resistance-loss air inlet Y-shaped pipe can realize the combination of air inlet pipelines within the limited structural space and pipeline loss requirements, and meets the use requirements of modern ships.
The pipeline loss calculation and the test show that the resistance of the air inlet Y-shaped pipe is small about 383Pa, the air inlet vacuum degree and the nature performance of the diesel engine are not influenced, and the use requirement is met.
