Variable frequency water supply control system based on secondary pressurization water supply and working mode thereof
The invention discloses a variable frequency water supply control system based on secondary pressurization water supply and a working mode thereof and solves the problem that in the prior art, no system special for water supply is available. The variable frequency water supply control system based on the secondary pressurization water supply is characterized by comprising a first pump, a second pump, a third pump, a fourth pump, an auxiliary pump, pressure sensors and a control system body which is composed of the processor 6ES7214-2BD23-0XB8 and the programmable controller S7-200, wherein an M end of the programmable controller S7-200 is connected with inlet pressure and outlet pressure feedback signals; the processor 6ES7214-2BD23-0XB8 comprises detection output ends 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 1.0 and 1.1 and detection input ends I0.1, I0.2, I0.3, I0.4, I0.5 and I0.6. The system is simple in structure, low in cost, convenient to maintain, stable in equipment quality, high in intelligentization degree and simple to control, and by means of the system, defects existing in the prior art are effectively overcome.
