Abstract: A coalescing removal separator includes a separator tank and a coalescing media. The separator tank has a separator input that receives a fluid flowing through an HVAC system having entrained gas and solid particles, has a tank wall that forms a volume/chamber inside the separator tank to process the fluid, and has a separator output that provides processed fluid having at least some, most or substantially all of the entrained gas and solid particles removed. The coalescing media is arranged in the volume/chamber of the separator tank, has a series of vertically aligned corrugated perforated sheets substantially filling the volume/chamber of the separator tank and removes the at least some, most or substantially all of the entrained gas and solid particles from the fluid.

Abstract: A spiral heat exchanger features first spiral channels configured to form rows and columns of coiled hot fluid pathways to receive hot fluid; and second spiral channels configured to form corresponding rows and columns of coiled cold fluid pathways to receive cold fluid having a temperature less than the hot fluid. The first spiral channels and the second spiral channels are configured to alternate every other row and column so as to form a matrix of alternating rows and columns of coiled hot and cold fluid pathways separated by alternating coiled walls that act as both fluid separators and conduits through which heat is transferred between the hot fluid and cold fluid.

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: A pump controller features a signal processor configured to respond to signaling containing information about three corresponding discrete arrays with respect to a discrete motor speed for each system position at a motor speed derived from 3D discrete distribution surfaces of motor power, pump differential pressure and flow rate by respective numerical interpolations; and determine corresponding signaling containing information to control a pump, or pumps in a system of pumps, or a system of pumps based upon a corresponding pump differential pressure and flow rate at the motor speed for a corresponding power reading value determined using a numerical interpolation of the three corresponding discrete arrays, the signaling received. The signal processor is configured to provide the corresponding signaling as control signaling to control the pump, or the pumps in the system of pumps, or the system of pumps.

Abstract: Apparatus, including a pump system, features a controller having a signal processor or processing module configured to: receive signaling containing information about a relationship between frequencies of pump vibration resonances detected around critical pump speeds and a 3-dimensional pump vibration power spectrum in the frequency domain with respect to pump speed and pump temperature change differences; and determine corresponding signaling containing information to adjust the pump speed to avoid the pump vibration resonances around the critical pump speeds, based upon the signaling received. The signal processor or processing module is also configured to provide the corresponding signaling as control signaling to adjust the pump speed.

Abstract: A suction diffuser or arrangement is provided featuring a main suction diffuser body and a flow conditioning arrangement. The main suction diffuser body is configured with an inlet to receive an incoming fluid flow, an interior cavity to receive the incoming fluid from the inlet, and an outlet to receive the incoming fluid from the interior cavity and provide an outgoing fluid. The flow conditioning arrangement is configured in relation to the inlet and also comprises a flow conditioning portion having at least one inwardly contoured surface, configured to extend into the interior cavity, diffuse the incoming fluid passing from the inlet into the interior cavity, and provide a flow conditioning that produces a uniform flow of the outgoing fluid by directing the incoming fluid towards the outlet, based at least partly on a contoured design corresponding to the at least one inwardly contoured surface.

Abstract: A pumping system featuring a pump, motor, a bearing assembly, integrated data acquisition system and combined programmable logic controller (PLC), data acquisition and modem. The pump couples to a pump shaft that responds to a pump shaft force to pump a liquid. The motor couples to the pump shaft, responds to VFD/VSD control signaling and provides the pump shaft force to drive the pump shaft. The bearing assembly includes a bearing with the pump shaft arranged therein and couples the pump and the motor. The variable frequency/speed drive (VFD/VSD) receives PLC control signaling and provides the VFD/VSD control signaling to drive the motor. The integrated data acquisition system responds to PLC data acquisition signaling, and provides integrated data acquisition system signaling containing information about an integrated set of pumping system parameters related to the pump, the bearing assembly, the motor and the VFD/VSD in the pump system. The combined programmable logic controller (PLC), data acquisition and modem provides the PLC data acquisition signaling and receive the integrated data acquisition signaling, provides PLC data acquisition modem signaling that exports performance data to the Internet to allow remote manual monitoring of the pump system, and provides the PLC control signaling to control the VFD/VSD and operate the pumping system as a controlled, closed loop system.

Abstract: A pump controller has a signal processor that receives signaling about an instant water level AIL of a liquid in a container and generated by a water level transducer during an empty/fill application; and determines corresponding signaling to control a pump during the empty/fill application based upon the signaling received using a liquid level control algorithm that turns ON the pump when the instant water level AIL rises above a maximum empty water level during an empty application, or falls below a maximum fill water level during a fill application; turns OFF the pump when the instant water level AIL falls below a minimum empty water level for the empty application, or rises above a second maximum fill water level during the fill application; controls the pump when the instant water level AIL is in a liquid level region above the minimum empty water level and below a second maximum empty water level for the empty application, or falls below the second maximum fill water level and above a second minimum fill water level during the fill application based upon a respective desired adaptive pressure set point SP* being defined from a respective adaptive liquid level control curve with respect to the instant water level AIL.

Abstract: A contoured check valve disc features a pivot portion and a check valve portion. The check valve portion is attached to the pivot portion, and has two sides, a first side to respond to the fluid flow in a first direction and move the check valve portion away from a fluid opening to the one or more open positions depending on the fluid flow to allow the fluid to flow through the fluid opening, and a second and opposing side to respond to fluid flow in an opposite direction through the fluid opening and move the check valve portion towards the fluid opening to the closed position to seal the fluid opening and stop fluid flow. The check valve portion a near-sloped portion formed nearest to the pivot portion, having a near-sloped contoured surface curving away from the pivot point to a first point of inflection with a first curvature, and a far-sloped portion formed farthest from the pivot portion, having a far-sloped contoured surface curving away from the point of inflection towards a farthest point away from the pivot portion with a second curvature that is less curved or bent than the first curvature, the near-sloped portion and the far-sloped portion combining to form a combined surface having a contoured pressure/force distribution on the first side to respond to the fluid flow and move the check valve portion away from the fluid opening.
