Abstract: The end fitting of the present invention is generally hollowly cylindrical in shape and sized so that the outer diameter of the end fitting is slightly larger than the outer diameter of the well screen to which the fitting is to be joined. Bores are formed in the body of the end fitting. The number and placement of bores in the end fitting should be such that the number and placement of bores in the end fitting match the number and placement of longitudinal rods in the well screen. The end fitting is mounted to the well screen by means of inserting each of the longitudinal rods of the well screen into each of the bores in the end fitting. The end fitting is permanently secured to the well screen by swaging the end fitting so that the fitting is compressed about the longitudinal rods. Alternatively, adhesive may be used to secure the longitudinal rods in the bores of the end fitting. In an alternative embodiment of the invention, the bores are drilled completely through the end fitting.

Abstract: The lubricating oil removal device and method of the present invention provides a device for intercepting the oil used to lubricate the line shaft bearings of an oil lubricated turbine pump before the oil can contaminate the water. Holes are provided in the oil tube below the bottom bearing to be lubricated and above the relief ports typically provided in the bowl assembly. An annular relief collar is provided around the oil tube at the location of the holes. A drainage pipe allows oil to flow from the relief collar to a reservoir located on the outside of the column pipe. A pump located within the reservoir lifts oil from the reservoir, through a tube, and onto the surface for reuse or disposal.

Abstract: Because mechanical aerators are located in a pond of liquid and, therefore, not subject to convenient visual monitoring by operations personnel, it is desirable to have a method for automatically detecting and dislodging debris which become caught on the aerator propeller. The present invention includes a waterproof vibration sensor mounted within sensing range of the rotating shaft of the aerator propeller. The sensor is operably connected to the propeller motor so that when the sensor detects excessive rotating shaft vibrations caused by debris attached to the propeller, the motor is automatically shut down and then run in the reverse direction causing the debris to be thrown off the propeller. Once the debris have been dislocated from the propeller, the motor is restarted in the forward direction. If the sensor continues to detect excessive motor shaft vibration, the motor will once again be shut down and then run in the reverse direction.

Abstract: A device and method for detecting bearing overheating in oil-lubricated turbine pumps comprising and temperature transmitting collar and infrared sensor. The temperature transmitting collar is mounted on the pump line shaft immediately adjacent to the stretch bearing, which is the top bearing in the pump system. The infrared sensor is positioned within sensing distance of the temperature transmitting collar and control circuitry is provided to warn of abnormal temperatures and to turn the pump off if temperatures continue to rise to an alarm condition.

Abstract: A deep well water pump system has a temperature probe (17) in the air space above the top bearing (12), preferably in the oil inlet chamber (26), and provides means for signalling abnormal temperatures to warning and system shutdown means. A method of detecting bearing overheating indirectly by sensing the shaft temperature and/or the temperature in the enclosed air space above the bearing is disclosed.
