Abstract

The invention discloses a through-flow turbine corrosion prevention model device which consists of a water tank, a water inlet pipe, a hydrometer, a pressure gauge, a valve, a through-flow turbine model, a drain tank, a water pump, a wet return pipe, a water tank support seat, a model support seat, a drain tank support seat, a water pump support seat, a potentiostat, a digital multimeter, a conductive electrode with an insulating shell, an electrode and an exhaust valve. The through-flow turbine corrosion prevention model device can be used for guiding the electrochemical protection scheme design of a real machine. Furthermore, the through-flow turbine corrosion prevention model device is also capable of evaluating and prejudging the potential problems such as uniform corrosion, spot corrosion, crevice corrosion and galvanic corrosion in the through-flow turbine model by a model test, thus providing reference basis for design and manufacture of the real unit.

Description

technical field [0001] The invention relates to a corrosion test model device, which is a device 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 ...
