摘要： Apparatus is provided featuring a signal processor or processing module configured at least to: receive signaling containing information about system energy consumption related to multiple pump combinations running in a multiple pump system; and determine whether to stage or de-stage a pump in the multiple pump system, based at least partly on the signaling received. The signal processor or processing module is configured to provide corresponding signaling containing information about whether to stage or de-stage the pump in the multiple pump system, and to implement control logic or a control logic algorithm based at least partly on the system energy consumption taking the form of specific energy that is a measure of energy used per unit mass for the multiple pump combinations running in the multiple pump system.

摘要： The invention relates to a pump device having a pump (8) and an energy supply device (5, 18), wherein the pump has a conveying element (9, 11) which conveys a fluid by means of supplied energy, wherein the pump has a transport state and an operating state, and wherein at least one first element (9, 9a, 10, 10′, 11) of the pump has a different shape and/or size in the transport state than in the operating state. The operating safety of such a pump device is increased by a detection device (12, 20, 21, 22, 23, 24, 25, 27, 28, 29) which detects whether at least the first element is in the operating state with respect to shape and/or size by means of a sensor.

摘要： A pumping apparatus for a jetted-fluid system includes a pump having an inlet connectable to the drain, and an outlet connectable to the return. The pump is adapted to receive the fluid from the drain and jet fluid through the return. The apparatus includes a motor coupled to the pump to operate the pump, a sensor configured to generate a signal having a relation to a parameter of the motor, and a switch coupled to the motor and configured to control at least a characteristic of the motor. The apparatus also includes a microcontroller coupled to the sensor and the switch. The microcontroller includes a model observer configured to receive a first value based on the signal and to generate a second value representative of at least one of a modeled flow or a modeled pressure based on the first value. The microcontroller is configured to control the motor based on the second value.

摘要： A method and apparatus are provided for controlling the operation of a pump, such as a centrifugal pump, featuring steps of either adjusting the operation of the pump, or issues a warning to a user of the pump of an undesirable operating condition, or both, based on a comparison of an actual torque value and a corrected torque value either alone or in combination with a further step of compensating the corrected torque value based on a mechanical power offset correction. The corrected torque value may include a Best Efficiency Point (BEP) torque value and may also be compensated for based on at least the current operating speed of the pump. The pump has a controller for performing the steps of the method. The controller can compensate the corrected torque value based on the square of the speed change of the pump. The comparison may include a ratio of the actual torque value to the corrected torque value.

The comparison may include a ratio of the actual torque value to the corrected torque value, and the ratio of the actual torque value to the corrected torque value may also be compared to ratios corresponding to either a dry run condition, a minimum flow condition, a runout condition, or some combination thereof.
