Process method for oil cleaning in the hydraulic pipeline dock of the ro-ro equipment of the ro-ro ship

Abstract

The invention relates to a process method for in-dock oil putting washing of a hydraulic pipeline of a roll-on / roll-off facility of a container roll-on / roll-off ship. The method includes the following steps that S1, a pipe to be subject to oil putting is pre-treated; S2, oil putting equipment is checked and washed; S3, the hydraulic pipeline is installed; S4, oil putting of the hydraulic pipeline is carried out; and S5, pipeline resetting after oil putting is carried out. According to the method, on the basis of existing equipment layout of the ship, the system pipeline moving direction is used, oil putting equipment such as an oil putting hydraulic unit, a temporary hose, a connector and an oscillator are distributed, it is guaranteed that the oil putting results meet the requirement, layout of the equipment on the ship and a pipe system is sufficiently used, the pipe disassembling, assembling and oil putting time is shortened, the oil putting washing period of the hydraulic pipeline is shortened, an in-dock production joints are well used, the in-dock hydraulic pipeline oil putting washing task is completed, and sufficient time is guaranteed for follow-up equipment debugging.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a process method for oil-throwing and cleaning in a hydraulic pipeline dock of a ro-ro ship ro-ro equipment. Background technique [0002] At present, the ro-ro equipment of the ro-ro ship includes the stern ramp, the stern door and the isolation door in the ro-ro area. The stern ramp and the stern door must be opened and closed in the dock to meet the requirements of the ro-ro equipment test in the dock and the subsequent wharf work. Requirements, and most of these equipment are hydraulic power equipment, so the oil cleaning of the hydraulic pipeline of the ro-ro equipment in the dock is an important link that affects the production node. Combining the experience of domestic and foreign ro-ro ship manufacturers, there are the following difficulties in docking oil: [0003] First, the hydraulic pipeline that needs to be oiled involves a lot of equipment, the pipeline is complicated, ...

AI Technical Summary

Problems solved by technology

[0003] First, the hydraulic pipeline that needs to be oiled involves a lot of equipment, the pipeline is complex, there are many extensions of the branch, the pipe diameter is various, and the pipeline accessories are various, so it is necessary to carry out multiple oil injections in batches

If oil is injected in series at one time, the final oil injection effect will not be achieved due to long pipelines, various accessories, and insufficient power.

[0004] Second, the cleanliness requirements of the system are high, the ro-ro equipment in the dock needs to be put into use, and the docking period is tense
