Description

technical field [0001] The invention relates to the technical field of antifouling coating performance evaluation devices, in particular to an antifouling coating performance evaluation device and method for simulating seawater pumping and storage operation conditions. Background technique [0002] The seawater pumped storage system refers to a new form of pumped storage that uses seawater as the working medium on the basis of the traditional pumped storage system. Due to long-term service in seawater medium, the flow-through parts of seawater pumped storage units are very easy to adhere to sea organisms. On the one hand, the adhesion of marine organisms will accelerate the corrosion of the flow-passing parts of the unit, and on the other hand, it will seriously reduce the operating efficiency of the unit, and even cause the unit to shut down. Coating anti-fouling coating is one of the economical and effective methods commonly used to solve the problem of marine biofouling....
