Device and method for detecting bearing overheating in turbine pump systems
First Claim
1. A means for detecting bearing overheating in a turbine pump system having a pump column and discharge head for fluid flow, an oil tube centered in said pump column and extending upward to a stretch assembly positioned above the area of fluid flow through said discharge head, a line shaft centered within said oil tube and extending through said stretch assembly, said means comprising a collar of temperature transmitting material mounted on said line shaft adjacent to said stretch assembly, and an infrared sensor placed within sensing distance of said collar.

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.
