摘要:
A bearing monitoring system is provided including one or more bearings (308,310,312,314) within a flow passage (306) and a working fluid passing over at least one surface of the bearings. A first thermocouple (316) is located in the flow passage upstream relative to the one or more bearings (308,310,312,314) and configured to measure a first temperature of the working fluid and a second thermocouple (318) is located in the flow passage downstream relative to the one or more bearings (308,310,312,314) and configured to measure a second temperature of the working fluid. The system further includes a control device (328) in communication with the first thermocouple (316) and the second thermocouple (318), and configured to compute a temperature gradient across the one or more bearings (308,310,312,314) from the first temperature and the second temperature, compare the temperature gradient against a known value, and if the temperature gradient exceeds the known value, the control device is configured to provide an alert.
摘要(中):
提供一种轴承监测系统,其包括在流动通道(306)内的一个或多个轴承(308,310,312,314)和通过轴承的至少一个表面的工作流体。 第一热电偶(316)相对于一个或多个轴承(308,310,312,314)位于流动通道的上游,并且构造成测量工作流体的第一温度,并且第二热电偶(318)位于相对于 所述一个或多个轴承(308,310,312,314)并且构造成测量所述工作流体的第二温度。 该系统还包括与第一热电偶(316)和第二热电偶(318)连通的控制装置(328),并且被配置为计算来自第一温度的一个或多个轴承(308,310,312,314)和第二温度 温度,将温度梯度与已知值进行比较,如果温度梯度超过已知值,则控制装置被配置为提供警报。
