Abstract: A condition monitoring device for monitoring machinery includes a combination of on-board sensors and a condition monitoring module. The on-board sensors include modules for non-contact temperature, magnetic flux and 3-axis vibration sensing of the machinery. The condition monitoring module provides a condition monitoring signal containing information about an operating condition of the machinery, based upon a data synthesis condition monitoring technique that synthesizes non-contact temperature, magnetic flux and 3-axis vibration sensed data received from the combination of on-board sensors, determines a current operating condition of the machinery, and compares the current operating condition and the baseline operating condition of the machinery.

Abstract: An automatic self-driving pump system features a pump/motor/drive detector and an automatic self-driving and control design/setup module. In operation, the pump/motor/drive detector receives sensed signaling containing information about a pump/drive for operating in a hydronic pump system, e.g., stored in and sensed from a signature chip or barcode installed that can be scanned by a scanner, and provides corresponding database signaling containing information about parameters for providing automatic pump control design, setup and run to control the pump/drive for operating in the hydronic pump system, based upon the sensed signaling received. The automatic self-driving and control design/setup module receives the corresponding database signaling, and provides control signaling containing information for providing the automatic pump control design, setup and run to control the pump/drive for operating in the hydronic pump system, based upon the corresponding database signaling received.

Abstract: A vertical in-line split couple pump includes a motor shaft having a motor shaft collar; a pump shaft having a pump shaft collar with a pump shaft angled collar surface oblique to an axis of the motor and pump shafts; and a coupler having coupler halves that attach together, that have a couple groove to receive the motor shaft collar, and have a couple angled groove to receive the pump shaft collar. The couple angled groove has a couple angled groove surface oblique to the axis. The coupler halves respond to a force that moves them together to couple the pump and motor shaft together, moves the pump shaft angled collar surface in relation to the couple angled groove surface, causing the pump shaft to move upwardly towards the motor shaft along the axis, to provide a way to jack-up and recouple the pump shaft and any impeller attached thereto by one mechanic.
