摘要： A signal processor is provided comprising one or more signal processor modules configured to: compare signaling containing information about historical data related to the performance of a pump; and provide corresponding signaling containing information about predicted maintenance needs of the pump on a real time basis based at least partly on the signaling compared containing information about the historical data related to the performance of the pump. The one or more signal processor modules may be configured to compare over time the hydraulic power generated by the pump and electric power consumed by a motor driving the pump, including tracking a ratio of hydraulic to electric power. The one or more signal processor modules may be configured to predict maintenance needs based on an algorithm that takes into account a trade-off between the cost of power consumed by a motor driving the pump and the cost associated with the pump maintenance in order to substantially minimize the total cost of operating the pump.

摘要： A method and apparatus are provided to control of a flotation separation process, including parameters of the flotation process and reagent addition to optimize mineral recovery. The apparatus includes a signal processor or processing module configured at least to receive signalling containing information about at least one acoustic characteristic of a froth layer in a flotation cell or tank of a flotation separation process; and determine a control characteristic related to the flotation separation process based at least partly on the signalling received. The signal processor or processing module may also be configured at least to: provide corresponding signalling containing information to control the flotation separation process based at least partly on the control characteristic determined.

摘要： The present invention provides a processor or signal processing module that features one or more modules configured to receive an input signal containing information about the unsteady pressures or acoustic emissions caused by a medium flowing through a pump, and also configured to provide of an output signal containing information about the performance of the pump. The information about the performance of the pump may include information about pump performance monitoring by a slip flow measurement, about predicting impeller wear, about pump impeller cavitation monitoring, about pump monitoring through acoustic emissions, about pump leak detection, about pump efficiency monitoring and about positive displacement pump monitoring.
