In the event of a major failure, the entire water treatment process will be paralyzed, bringing great inconvenience to the people's lives and production. According to the current analysis of the operation of the pump in the S series, the common faults are: The impeller has been subjected to surface corrosion in the sewage for a long time, the early fatigue fracture of the blades, the wear of the pump body overflow parts, the bending of the pump shaft, the burnout of the motor and the bearing, etc. It is very important to study the operation Safety, through the research of this content, not only improve the safety of the pump, but also improve its service life. And in the process of water treatment work, the use of the system is often changed, if not in accordance with the needs to be met, will affect the normal operation of production, resulting in greater waste. In order to manage effectively, it is necessary to carry out remote monitoring and field control of production system, and in order to improve production efficiency and safety, it is also necessary to detect the key parts of the pump in the S series. Thus, the research of automatic control technology is an important technology development trend.
