Design of Underwater Grinding Device for Nuclear Power Plant

In order to solve the problems of difficulty in cleaning the inner wall of the hammer-shaped component in the RIC system of the nuclear power plant and the low surface accuracy after cleaning, a profiling cleaning system was designed. First, the working principle of profiling cleaning is introduced to ensure that the surface accuracy after cleaning meets the installation requirements. Secondly, in order to ensure the normal operation of the profiling airbag, a mechanical model between the air supply volume of the air pump and the force on the conical inner wall is derived. Finally, in order to accurately control the output torque of the motor, the PID method is used to control the output torque of the motor. The system can increase the success rate of cleaning the inner wall of the hammer-shaped component in the RIC system and improve the efficiency of nuclear power plants.
