Problems solved by technology

On the one hand, the general pollution control system is difficult to meet the filtration requirements of pollutants in seawater with various types and wide size distribution, and the pollution control ability is weak; on the other hand, it does not have the online recovery function of the filtration ability, and cannot feedback the pollution of the filter in real time Therefore, it cannot meet the working requirements of the open seawater hydraulic system

Abstract

The invention discloses an open-type seawater hydraulic pollution control system for deepwater operation facilities, and the open-type seawater hydraulic pollution control system is formed by serially joining a plurality of grading-type backwash filter levels, wherein each backwash filter level is formed by joining two or more than two basic unit branches in parallel; the multiple backwash filter levels are two or more than two backwash filter levels; and the serial connection way of the grading-type backwash filter levels is that the front end of a backwash filter level is connected with a backwash rough filter level with identical structure and low filter precision, and the rear end of the backwash filter level is connected with a backwash fine filter level with identical structure and high filter precision. The grading-type multilevel filtering is adopted, the system is formed by serially joining multiple grading-type backwash filter levels, so that each backwash filter level can share the pollution load and have strong pollution control capacity for the characteristics that the pollutant types in the seawater are diversity and the size distribution is wide. A method for backwashing the backwash filter is adopted to restore the filter capacity.

Description

technical field [0001] The invention relates to deep sea operation equipment, deep submersibles, underwater remote control robots and other underwater open hydraulic systems, in particular to an open seawater hydraulic pollution control system for deep sea operation equipment. Background technique [0002] At present, oil pressure hydraulic systems with pressure compensation are widely used in deep submersibles, underwater remote control robots, underwater construction, and deep sea operation equipment. It has the advantages of being compatible with the marine environment, being clean and environmentally friendly, not requiring pressure compensation, and saving bulky fuel tanks, etc. It is more and more widely used in underwater working tools and equipment. The transmission medium of the open seawater hydraulic system comes from the seawater environment and must be filtered to meet the filtration accuracy of the seawater hydraulic pump before entering the seawater hydraulic ...
