摘要： A method for determining faults during the operation of a pump unit. At least two electric variables that determine the electric output of the motor and at least one fluctuating hydraulic variable of the pump are detected. The detected values or values formed from the variables by use of algorithms are automatically compared to predefined stored values using electronic data processing and the results of the comparison are used to determine whether or not faults have occurred.

摘要： A pump or DC fan used to cool an electronic system is monitored for speed. When the pump or fan encounters an unexpected increase in impedance, such as an obstruction or a bearing anomaly, the controller temporarily increases the power to the pump or fan to overcome the impedance, and optionally notifies the user of the pump or fan problem. Also, when the pump or fan impedance returns to a normal range, the controller returns the power to the pump or fan to normal levels. In some embodiments, the controller may supply more power to the pump or fan than specified by the manufacturer to temporarily over come the increased impedance or pending failure of the pump or fan. This increased power allows the fan or pump to operate at a speed necessary for cooling an electronic system during a temporary increase in impedance, or during a slow degradation of the efficiency of the fan or pump.
摘要翻译：监控用于冷却电子系统的泵或直流风扇的速度。当泵或风扇遇到阻塞（例如阻塞或轴承异常）的意外增加时，控制器暂时增加泵或风扇的功率以克服阻抗，并且可选地通知用户泵或风扇问题。此外，当泵或风扇阻抗恢复到正常范围时，控制器将泵或风扇的电源恢复到正常水平。在一些实施例中，控制器可以比制造商提供比泵或风扇更多的功率，以暂时超过泵或风扇的增加的阻抗或未决的故障。这种增加的功率允许风扇或泵在暂时增加阻抗期间或在风扇或泵的效率的缓慢降低期间以冷却电子系统所需的速度运行。

摘要： The present invention provides cavitation detection systems and methods employing a classifier for detecting, diagnosing and/or classifying cavitation in a pumping system. The classifier can be integral to tie cavitation detection system and/or operatively coupled to the cavitation system via a controller, diagnostic device and/or computer. Parameters such as flow, pressure and motor speed arc measured and/or estimated, and then provided to a classifier system Such systems include Bayesian, Fuzzy Set, nonlinear regression, neural networks and other training systems, for example The classifier system provides a signal indicative of the existence and extent of cavitation. An exemplary classification system is presented that delineates cavitation extent into one or more of the following categories: 0 (no cavitation), 1 (incipient cavitation), 2 (medium cavitation), 3 (fill cavitation) and 4 (surging cavitation). The cavitation signal can be utilized for monitoring and/or controlling a pumping system to mitigate pump wear, failure and other conditions associated with cavitation.

摘要： A submersible pumping system which, in one embodiment, includes a motor, a pump and a control circuit, or unit, coupled to the motor for controlling the operation of the motor is described. Using motor and sensor signals, the control unit detects various conditions within the pumping system and alters motor operation. In an exemplary embodiment, the control unit initiates an oscillation sequence of applying a forward torque for a first preselected period of time, applying a reverse torque for a second preselected period of time, and then repeating the torque applying steps a selected number of times to eliminate an obstruction from the pump.
