Problems solved by technology

[0002] Generally, the hydraulic system is washed in series in the workshop and the pressure test is completed, and then the flushing of the pipeline system on board the ship is carried out. Considering the tension of the periodic construction and the complexity of the pressure test and flushing work of the hydraulic system, the general cycle is longer.
[0003] There are many hydraulic piping systems in the whole ship of wind power installation ships, and the cleaning requirements are high. For example, according to the requirements of oil transfer in the workshop, the cycle is long and the cost is high

Embodiment Construction

[0016] The invention discloses a hydraulic pipeline cleaning method, the main steps of which are as follows:

[0017] 1) Sponge bullets: Use the cleaning air gun to inject the sponge bullets into the hydraulic pipeline at high speed with the help of high-pressure air. The high-speed sponge bullets are coated with pipeline cleaning fluid, which can effectively remove oil and impurities inside the hydraulic oil pipes;

[0018] 2) String washing: select the oil with the same oiliness as the working one, put the oil into the hydraulic pipeline for string cleaning, stop and start the circulating oil pump intermittently during this process, and open the shut-off valve in the system intermittently Open small to promote fluctuations in the fluid in the tube; if no visible particles are found for three consecutive times, the string washing is completed;

[0019] 3) Pressure test: the safety valve of the system is adjusted to the selected pressure test value, and oil is supplied to the ...

Abstract

The invention relates to a hydraulic pipeline cleaning method. The method mainly comprises the following steps of shooting sponge bullets, wherein a cleaning blower gun shoots the sponge bullets intoa hydraulic pipeline with the help of high-pressure blast at high speed; intermingling and cleaning, wherein oil the same as the oiliness of oil at work is selected, and the oil is poured into the hydraulic pipeline to be intermingled and cleaned; testing pressure, wherein a safety threshold valve of a system is adjusted to a selected pressure testing value to supply oil to the system, when pressure is tested, grading pressure test is normally adopted, when a grade is added, inspection is carried out once, and a prescribed pressure testing value is achieved by grading step by step; flushing, wherein a flushing loop is determined, and a recycle flushing method is adopted to flush the hydraulic pipeline continuously. The hydraulic pipeline cleaning method has the advantages that the hydraulic pipeline shoots the sponge bullets in a workshop to replace workshop intermingling and cleaning work, part of pipeline inner wall dirt is removed in advance, therefore, the pipeline intermingling and cleaning time is shortened, the overall efficiency is improved, the intermingling and cleaning period is shortened, and the cleaning cost of the hydraulic pipeline workshop is effectively reduced.

Description

technical field [0001] The invention relates to the field of hydraulic systems, in particular to a hydraulic pipeline cleaning method. Background technique [0002] Generally, after the series washing and pressure testing of the hydraulic system are completed in the workshop, the flushing of the piping and shipboard system is carried out. Considering the tension of the periodical construction and the complexity of the pressure testing and flushing work of the hydraulic system, the general period is longer. [0003] Wind power installation ships have a lot of hydraulic piping systems on board, with high cleaning requirements, such as oil transfer requirements in the workshop, long cycle times and high costs. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a hydraulic pipeline cleaning method that improves the overall efficiency, reduces the time for serial cleaning of pipelines, and reduces the cleaning cost.
