Complex pipe network multi-branch parallel cleaning scheme design method and cleaning method

Abstract

The application discloses a complex pipe network multi-branch parallel cleaning scheme design method and a cleaning method, adopts an electric control series valve to connect branches of a pipe system to form closed branches, and calibrates the flow resistance of each branch; according to the maximum flow of a cleaning oil vehicle and the cleaning flow requirement of a single branch, the maximum number of parallel cleaning is determined; according to the maximum number of parallel cleaning, branches with similar flow resistance are selected for parallel cleaning. The multi-branch parallel cleaning method based on the flow resistance characteristics is adopted, the micro electric control series valve is used to connect the branches to form closed branches, the flow resistance characteristics of each branch are tested, the multi-branch parallel cleaning is realized, and the cleaning efficiency of the complex pipe network pipe is improved under the condition of ensuring the cleaning flow of each branch.
