Abstract

A smart molten metal pump system and method automatically controls the operating speed of the pump rather than requiring an operator to control the speed. The system includes a pump, a controller for controlling the speed of the pump and one or more vibration sensors (such as an accelerometer) to measure vibration. The controller receives input about the vibration of the pump or one or more pump components, and possibly other data, such as the temperature of the molten metal, and/or the depth of the molten metal, ad/or parameters related to the operation of the pump. The controller analyzes the one or more inputs to vary the speed of the pump, turn the pump off, and/or send a communication to an operator.
