Method of cleaning pipeline of lubricating oil, hydraulic oil and fuel oil

Abstract

The method of cleaning pipeline of lubricating oil, hydraulic oil and fuel oil includes following steps: A. forming temporary cleaning pipeline with main pipeline, cleaning liquid tank, temporary sectional cleaning pipeline, valve, water pump and filter; B. de-oiling, derusting and cleaning with the cleaning liquid compounded with neutral derusting detergent and water in the weight ratio of 1 to 3-8 for 20 hr before draining; C. twice rinsing and preventing rust with the cleaning liquid compounded with water-base antirust agent and water in the weight ratio of 1 to 5-10; and D. drying inside of pipeline with compressed air of 0.6-0.8 Mpa. The present invention has high efficiency, high cleaning quality, operation safety and other advantages.

Description

technical field [0001] The invention relates to a cleaning method for lubricating oil, hydraulic oil, and fuel oil piping, in particular to a method for cleaning lubricating oil, hydraulic oil, and fuel piping with an aqueous solution of cleaning agent. Background technique [0002] At present, large-scale equipment such as petrochemicals, locomotives, ships, mining machinery, etc. are usually installed at the production site. Before the installation of the piping system, the oil, rust, debris, etc. in each piping system must be cleaned , cleaning, first pickling, neutralizing, and drying each piping system component, and then installing it. After all piping systems are installed, oil can be carried out. However, due to the complexity of the piping system and sometimes negligent operations, many Most of the piping systems have oil stains and corrosion before the oil is used, which has to greatly prolong the oiling time of the entire piping system; at this time, the usual pra...

Problems solved by technology

[0002] At present, large-scale equipment such as petrochemicals, locomotives, ships, mining machinery, etc. are usually installed at the production site. Before the installation of the piping system, the oil, rust, debris, etc. in each piping system must be cleaned , cleaning, first pickling, neutralizing, and drying each piping system component, and then installing it. After all piping systems are installed, oil can be carried out. However, due to the complexity of the piping system and sometimes negligent operations, many Most of the piping systems have oil stains and corrosion before the oil is used, which has to greatly prolong the oiling time of the entire piping system; at this time, the usual practice is to unload the installed pipelines and transport them back to the manufacturer. The manufacturing plant re-pickled, neutralized, dried, and then went to the production site to install the oil, which not only consumes a lot of manpower and material resources, but also prolongs the oil oil cycle, which affects production and causes undue economic losses.
