Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, and in particular to a device for assisting in cleaning a fuel pipeline of a ship. Background Art

[0002] During the construction phase of the ship at the dock, before the equipment is put into operation, it is necessary to ensure that the inside of the pipeline is clean and free of impurities to prevent impurities from entering the equipment during operation and causing damage to the equipment. After the fuel pipeline is fully installed, it will be idle for a long time, causing rust in the pipeline and impurities to enter the pipeline. Therefore, it is necessary to use relevant rust removers and rust inhibitors to remove the floating rust and garbage inside the pipeline. Then use diesel to wash the pipeline in series to remove the water vapor in the pipeline and some impurities that cannot be removed by rust removers.

[0003] During the fuel injection process, due to the location of the injection truck and the injection pressure, it is necessary to regularly remove the injection hose connected to the injection truck, change the inlet and outlet of the injection truck connected by the hose, and then reconnect the injection truck and the injection hose. This method can be used to change the flow direction of diesel in the injection pipeline to avoid dead corners in the injection process, resulting in low injection efficiency and unclean injection. However, this method is difficult to operate, takes a long time, and is prone to mixing garbage at the pipeline connection during the disassembly and assembly process.
