| Abstract: | A kind of HMI configuration control water-supplying system for constant pressure is introduced in this paper.The constant pressure water supply system are realized with frequency converter controlling by PLC,which can start water pumps automatically,change the revolution of pumps and adjust the amount of the water supply in a closed ring with constant pressure in order to control the flow of the system in constant pressure.The method makes the system more stable and reduces the cost of the main pipe energy-saving in power plant. |
