With the development of China's economy , the energy consumption is increasing , traditional electricity power generation mode can not meet the people 's growing demand for electricity , the construction of nuclear power plants in order to ease the pressure of the growth in demand for electricity , increasing number of presence of radiation , but nuclear energy Therefore, the reliability of nuclear power equipment , security put forward higher requirements. Drum -type rotary filter is a large thermal power plant and nuclear power plant water supply system water treatment equipment , and can effectively remove the water larger than the mesh vegetation , fish and other debris , also can be used for urban environmental protection , water supply , metallurgy , chemical industries such as water supply and drainage system . Drum-type filter drum skeleton , spindle assembly , drives , flushing water systems , lubrication systems , sealing systems , operating platform , electrical controls , cathodic protection , anti-corrosion devices . The drum-type filter is driven by the drive means on the drive shaft pinion gear, and drives the rotation of the large gear ring of the drum the web . Large finite element simulation - based analysis software ANSYS , drum-type filter has conducted a static stress analysis, modal analysis , seismic design analysis . In order to facilitate the meshing improve problem - solving accuracy , drum -type filter model is created directly in the ANSYS environment . Based on the work of drum -type filter , drum network inside and outside the water level difference of different static analysis is divided into three conditions analyzed . Seismic analysis using the response spectrum analysis and time history analysis are two ways to check , draw a critical point of displacement , stress -time curve .
