Abstract

The invention belongs to the technical field of performance evaluation of ship propeller protection matching materials, and particularly relates to a device and a method for testing environmental adaptability of a ship propeller protection matching coating. The device simulates pitch angles and linear speeds at different radiuses of a ship propeller, the operation condition of the ship propeller is simulated, the matching performance of the propeller blade under different pitch angles and different rotating speeds (linear speeds) can be tested in a laboratory, wherein the matching performancecomprises roughness rising, bubbling, falling and the like caused by seawater shearing; rapid evaluation of pollution prevention of the propeller and environmental adaptability of the matched coatingis realized; based on the characteristics of low consumption, rapid evaluation and conformity to the actual operation environment, the development period of the protective coating is shortened, the problem of coating application limitation caused by lack of a method for evaluating the environmental adaptability of the protective coating on the surface of the propeller is solved, and the method hasremarkable economic benefits and industry development promotion effect.

Description

Technical field: [0001] The invention belongs to the technical field of performance evaluation of ship propeller protective supporting materials, in particular to a device and method for testing the environmental adaptability of a ship propeller protective supporting coating, which can test propeller blades at different pitch angles and different rotational speeds (linear speeds) in a laboratory The following supporting performance. Background technique: [0002] The propeller is a key component of the ship propulsion system. Due to the harsh and complex service conditions, the fouling problem has not been solved. Marine biofouling can significantly reduce propeller propulsion efficiency, increase noise, and increase ship maintenance time. Studies have shown that only 3 months of fouling can reduce propeller propulsion efficiency by more than 10%, speed by 20%, and increase energy consumption. 40%, measures must be taken to prevent it. [0003] Marine antifouling coatings ...
