Self-aligning and vibration damping bearings in a submersible well pump

An electrical submersible pump assembly has a centrifugal pump with stages, each having an impeller and a diffuser. A shaft extending from an electrical motor rotates the impellers. In the stages, a thrust runner is coupled to the shaft for rotation in unison. A bushing is non rotatably mounted in a receptacle in the diffuser. The bushing has a bore that receives the body of the runner in sliding, rotating engagement. The bushing has a thrust receiving end engaged by the thrust face of the runner in rotating, sliding engagement to transfer thrust from the runner to the diffuser. An elastomeric compliant member between a cylindrical exterior of the bushing and the receptacle allows limited radial movement of the bushing relative to the diffuser.

SUMP PUMP TEST AND MONITORING SYSTEM

A proactive test and monitoring system for a sump pump installation of the type having an electrically-powered sump pump which pumps water from a sump pit to a dispersal site when the water level in the pit rises to a predetermined level. The system includes a control module which is periodically actuated by an event timer to initiate a test cycle wherein a valve is actuated open to admit water into the pit. If the pump is operative, the pump operates and the water level in the pit falls, the test cycle is terminated and a successful test is indicated. If the pump is inoperative, the water level continues to rise and the test cycle is terminated, the valve is closed and an unsuccessful test is indicated. Thus the sump pump installation is periodically tested to improve the reliability of the pump and to signal pump inoperability in advance of any potential flood event requiring operation of the pump installation. 1.

Test and monitoring system for a sump pump installation having a variable test cycle time out

An automated system for monitoring and testing a sump pump installation includes an electrically-actuated valve which admits liquid into the liquid container in response to a valve control signal. A test control module supplies a valve control signal to initiate a test cycle during which liquid is admitted to the container to cause the liquid level in the container to rise after which the pump, if functional, discharges liquid from the container and the test cycle is terminated. The test control module includes a timer circuit which, if the test cycle is not terminated by the pump, terminates the test cycle and terminates application of the valve control signal to the valve after a predetermined time out period following initiation of the test cycle. The test control module further includes an indicator circuit which indicates upon termination of the test cycle whether the test was successful or unsuccessful. In one embodiment the timeout period of the test cycle is dependent on the flow rate of liquid through the conduit.
