Description
technical field [0001] The invention relates to a control system and a control method of a water supply pump, relates to the technical field of water supply pump control, and is applied to the operation and control of water supply equipment. Background technique [0002] Most of the existing control systems of feed water pumps adopt simple pure mechanical control methods, manually or semi-automatically control the water pump to realize the liquid level control function, and the control devices such as PLC are used more often, but such a system structure is not only The cost is huge, the control speed and accuracy are relatively low, and there is no protection function for the water pump used on site, and the safety is not high. It has been unable to adapt to the continuously strict control requirements in industrial production and life. Contents of the invention [0003] In order to overcome the defects of the existing control system of the water supply pump, such as comp...
