Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0017] Such as figure 1 , figure 2 As shown, Step 1: According to the size of the real machine, according to the proportional relationship between the real machine and the model, increase the conductivity of the aqueous solution, prepare a diluted aqueous solution, and inject it into the water tank 1. Open the valve 3, so that the water in the water tank 1 is injected into the interior of the tubular turbine model 4 and the drainage box 5, and the drainage box 5 is connected with the tubular turbine model 4. Open the first exhaust valve 34 to discharge the air in the drainage tank 5, open the second exhaust valve 35 to discharge the air in the tubular turbine model 4, so that the aqueous solution is filled in the tubular turbine model 4 and the drainage tank 5 internal cavity.

[0018] Step 2: In the state of step 1, turn on the potentiostat 12, ...

Abstract

The invention discloses an anti-corrosion model test method of a tubular water turbine, which can reasonably calculate the conductivity of the water medium according to the size of the real machine to configure the solution, and through the reasonable distribution and current adjustment of the electrodes that function as auxiliary anodes, the selection is reasonable The potential distribution of the site test can optimize the number of electrodes and the potential distribution, and guide the design of the electrochemical protection scheme of the real machine. At the same time, the invention can also evaluate and predict potential uniform corrosion, pitting corrosion, crevice corrosion, galvanic corrosion and other problems in the tubular turbine model through model tests, and provide reference for the design and manufacture of real units.

Description

technical field [0001] The invention relates to a corrosion model test method, which is a method capable of evaluating the corrosion problem of a tubular water turbine and performing electrochemical protection and effect prediction. Background technique [0002] Tubular turbine is a typical turbine for tidal power station selection. When used as a tidal power plant for power generation, tubular turbines face serious corrosion problems in seawater media, such as uniform corrosion, pitting corrosion, galvanic corrosion, and crevice corrosion. If these problems are not considered in advance, serious corrosion failure problems will occur after the unit is in operation, which will bring huge economic losses to the power station. Therefore, it is of great significance to use the corrosion model device to conduct model tests in the laboratory environment in advance, evaluate and predict various corrosion problems, and make corresponding anti-corrosion countermeasures, which is of ...
