PURPOSE:To enable conversion into bearing load, display, record, and monitor, and prevent accident of rotary machine, by detecting the oil film pressure of oil film bearing on a rotary shaft. CONSTITUTION:One or plural pressure taps 3, 3', 3'' are provided in an oil film bearing 1 of a rotary machine, from which a guide tube is led, and a pressure detector 5 is connected behind a valve 4, and electric signals are taken out from a transducer 6. On the other hand, a thermocouple 7 and an amplifier 8 are provided to detect the temperature of the bearing oil film. Besides, in order to take out the rotating speed signal, a rotation detecting device 9 is provided. These signals are led from a static load converter 10 out into a static load display device 13, and, in order to improve the frequency characteristic, is guided from a dynamic load converter 11 into a dynamic load display device 14 through a frequency characteristic converter 12. The signals inputted into the display devices 13, 14 are inputted into discriminator and recorder. If abnormality is found, necessary signals are sent into an alarm device or a stopping device 16, so that adequate countermeasures may be done. |
