Abstract: This paper presents an intelligent control scheme for the lifting pump system with two working and one standby. By analyzing the control requirements and actual operation and maintenance requirements put forward by the craft specialty, the method of virtual pump number is put forward to smoothly realize the control demand for the conversion from high number pump to low number pump. In the case of random water inflow, the measures such as on-demand switching, sequential switching and fault tripping of the pump ensure the continuous and stable operation of the lifting pump system, The balanced output of the main pump and the standby pump is ensured, the working condition parameters of the pump are effectively optimized, and the non fault duration of the lifting pump system is increased, which provides a strong guarantee for the continuous and stable operation of the whole sewage treatment system.
Keywords: lifting pump; control scheme; main and standby switching; round cycle; distribution on demand
