High-efficiency cleaning method for novel hydraulic pipeline

Abstract

The invention discloses a new type of high-efficiency cleaning method for hydraulic pipes. After the steps of clean water cleaning, derusting cleaning, pipeline passivation treatment and hydraulic oil flushing, the high-efficiency cleaning of the new hydraulic pipes is completed; in the chemical cleaning process of the present invention, weak acid The solution only chemically reacts with oxides, without any damage to the iron crystal of the pipeline itself; after chemical cleaning is used in the present invention, the chemical solution will form a smooth protective film on the inner wall of the pipeline, which increases the usability of the pipeline system and prolongs the life of the pipeline. The service life of the pipeline. The invention adopts the idea that the chemical reaction speed is greater than the physical reaction speed, and uses the chemical agent aqueous solution to remove the oxides on the inner wall of the pipeline, reducing the difficulty of oil leakage in the later stage, which can shorten the cleaning cycle of the hydraulic pipeline, save resource waste, and improve production efficiency.

Description

technical field [0001] The invention relates to a cleaning method, in particular to a novel high-efficiency cleaning method for hydraulic pipes. Background technique [0002] With the continuous development and innovation of my country's marine technology, marine engineering plays a leading role in the global marine field. Hydraulic systems are used more and more in the field of marine engineering, and their stability has been recognized. With the continuous innovation of science and technology, the use of proportional valves in hydraulic systems is also becoming more and more intelligent and technological, so that the requirements for cleanliness of pipelines and the usability of pipelines are also continuously improved. With the continuous innovation and development of marine science and technology, the cleanliness requirements of the hydraulic system are constantly increasing, and the difficulty of string cleaning is also increasing. At the same time, based on the experie...

Problems solved by technology

[0003] For offshore platform projects, the hydraulic system plays a dominant role, and the time for serial washing plays an important role in the later equipment commissioning and project delivery. At the same time, there are some difficulties in the efficient cleaning of hydraulic pipelines: preventing hydraulic oil emulsification: efficient pipelines In the cleaning process, chemical cleaning is performed first, followed by hydraulic oil flushing. At the junction of the two steps, it is difficult to have an intersection point where water and oil are mixed. Once a certain ratio is exceeded, the hydraulic oil will emulsify and waste resources.
