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 inside of the tubular turbine model 4 and the drainage tank 5. 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, output current through the positive output terminal 21 to a plurality o...

Abstract

The invention discloses a corrosion model test method of a through-flow turbine. The conductivity of a water medium can be reasonably calculated according to the size of a real turbine so that a solution can be prepared; by carrying out reasonable distribution and current regulation on electrodes having the auxiliary anode effect and selecting a reasonable part to test potential distribution, the effects of optimizing the number of the required electrodes and potential distribution and directing the design of an electrochemical protection scheme of the real turbine can be achieved. Meanwhile, the potential problems of uniform corrosion, spot corrosion, crevice corrosion, galvanic corrosion and the like in a through-flow turbine model can be evaluated and prejudged through a model test, and reference can be provided for design and manufacturing of a real set.

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 ...
