Based on the virtual disassembly technology extended by virtual reality technology in the field of mechanical design and manufacturing, many experiments do not allow students to operate freely for various reasons, but are not affected in the computer. Since the training of employees in thermal power plants is generally based on the mentoring system, the training period is long and the effect is slow, so the virtual pump is used to model the front pump and build the fault library, including common mechanical faults, electrical fault types and disposal. The way to build the database, so that the...
