A maintenance device for ultra-long-term maintenance of reference electrodes

Abstract

The invention belongs to the field of equipment operation and maintenance of cathodic protection systems in the anticorrosion industry, and relates to a complete set of ultra-long-term maintainable reference electrodes, including a liquid storage tank, a main pipe connected to the liquid outlet of the liquid storage tank, and a liquid inlet connected to the main pipe The pipeline and the liquid inlet pipeline are respectively connected to the reference electrode through the first branch pipeline and the second branch pipeline. The first branch pipeline is connected with the first flushing pipe, and the second branch pipeline is connected with the second flushing pipe. The main pipeline is provided with a liquid storage tank outlet valve, the liquid inlet pipeline is provided with a magnetic pump, the first branch pipeline and the second branch pipeline are respectively provided with a backwash valve and a reference electrode inlet valve, and the outlet of the magnetic pump is provided with a pump An outlet valve, the first flushing pipe is provided with an outlet valve one, and the second flushing pipe is provided with an outlet valve two. The complete device of the invention is light in design, simple in operation and convenient in portability, which makes up for the gap that the long-term saturated Cu / CuSO4 reference electrode used in the industry cannot be maintained.

Description

technical field [0001] The invention relates to a maintenance device for ultra-long-term maintenance of reference electrodes, belonging to the field of equipment operation and maintenance of cathodic protection systems in the anti-corrosion industry. Background technique [0002] The reference electrode is mainly used to provide a reference when measuring the electrode potential of metal structures, so as to achieve its accurate quantitative and test measurement. Conventional Ceramic Cu / CuSO 4 Cu / CuSO in the electrode tank of the reference electrode during use 4 At the same time, in the vicinity of buried pipelines in offshore areas, the soil CI- is high due to seawater immersion, which makes the reference electrode exchange with surrounding ions during use, resulting in electrolytic pollution, reference potential offset and other problems, thus giving Field testing brings great error. [0003] There is no conventional ceramic Cu / CuSO in China 4 Reference electrode maint...

Problems solved by technology

Conventional Ceramic Cu / CuSO 4 Cu / CuSO in the electrode tank during the use of the reference electrode 4 At the same time, near the buried pipeline in the offshore area, due to the high CI- of the soil due to seawater immersion, the reference electrode is exchanged with the surrounding ions during use, causing problems such as electrolytic pollution and reference potential offset, thus giving On-site testing brings great error

[0003] There is no conventional ceramic Cu / CuSO in China 4 Reference electrode maintainable device, in order to solve the above problems, it is necessary to develop an ultra-long-term maintainable reference electrode complete set of conventional ceramic Cu / CuSO 4 On-line, ultra-long-term maintenance of the reference electrode, suitable for on-site application of cathodic protection of offshore pipelines
