Abstract:

A technique for determining pump flow without using traditional sensors features steps and modules for creating a calibrated power curve at closed valve conditions at several speeds; calculating coefficients from a normalized power curve based on a pump's power ratio; and solving a polynomial power equation for flow at the current operating point. The calibrated power curve may be created by increasing the speed of the pump from a minimum speed to a maximum speed and operating the pump with a closed discharge valve. This data is used to correct published performance for shutoff power and best efficiency point power at rated speed in order to determine the pump's power ratio. It is also used to accurately determine closed valve power at the current operating speed. The pump's power ratio is determined by the equation: P=P/P. The polynomial power equation may, for example, include a 3rd order polynomial equation developed using coefficients from the normalized power versus flow curve, and corrections may be made for speed, hydraulic efficiency and specific gravity in the polynomial power equation.

US Classification:

417 5

Abstract:

The present invention provides a new and unique method and apparatus for operating and running multiple pumps in a system together at a substantially synchronous torque to achieve a desired setpoint. Each of the multiple pumps may be operated with a variable speed drive. The present invention may also take the form of the system having the multiple pumps with a system controller for operating and running the multiple pumps, a pump for operating and running in such a system, a system control module for such a system controller, as well as a pump control module for running and operating such a pump.

International Classification:

F16H061/26

US Classification:

060445000

Abstract:

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, 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.

Abstract:

Technologies are generally described for an integrated monitoring system to monitor several operational aspects of a bearing assembly, analyze monitored aspects, provide predictions, alerts, and reports based on general equipment data or specific rotating machine data. A number of sensors in and on a bearing housing may sense a variety of operational aspects and provide input to a local or remote monitoring device. The bearing housing may include sensor mounting locations for one or more sensors. In some examples, an oil level sensor placed in a suitable mounting location on the bearing housing may detect oil levels inside the bearing housing. The monitoring device may analyze the sensor inputs in light of other information such as historic performance data, environmental information, etc. Reports, predictions, alerts, and/or suggested corrective actions may be generated based on the analysis by the monitoring device and/or remote devices communicatively coupled to the monitoring device.

International Classification:

F04D 25/08
F04D 25/06
F04D 29/54

Abstract:

A motor assembly includes an electric motor with an output shaft. A motor frame houses the electric motor so that the output shaft protrudes from an end of the motor frame. A plate assembly is coupleable about the output shaft to the end of the motor frame. The plate assembly has a cavity that houses motor drive electronics. The plate assembly further defines a duct that extends between a central opening and one or more openings on an outer radial wall of the plate assembly. A fan is configured to flow air over one or more surfaces of the plate assembly and causes to flow through the duct to inhibits heat transfer between the electric motor and the motor drive electronics.
