Embodiment Construction

[0017] Such as figure 1 The dynamic monitoring system for the running state of the thrust bearing of the hydro-generator shown includes a temperature sensor, a pressure sensor, an oil film thickness sensor, a host computer, and a remote computer. The host computer includes PCM-3363CPU module U1, PCM-3910 power supply module U2, and PCM-3835 memory Module U3, PCM-3718H multi-function acquisition module U4, signal conditioning module U5, wi-fi wireless routing module U6, among which U1, U2, U3, and U4 modules use PC104 bus, and there are pins and jacks for bus connection on the modules , U1, U2, U3, and U4 are sequentially connected together through these pins and jacks to form a stack structure. U5 is connected to the signal interface on U4 through a signal connection line, and U6 is connected to the network port of U1 through a network cable. The output signals of oil film thickness sensors S11, S12, S13, S14, pressure sensors S21, S22, S23, S24 enter the data acquisition car...

Abstract

The invention discloses a dynamic monitoring system for an operating condition of a thrust bearing of a hydro-generator. The system comprises a temperature sensor, a pressure sensor, an oil film thickness sensor, a host machine and a remote computer, wherein the sensor is arranged on a mirror plate of the thrust bearing for outputting lubricating parameter data such as oil film thickness, oil film pressure, oil film temperature and the like with the rotation of the mirror plate; and the data can be used for reflecting the operating condition of the thrust bearing. Data is exchanged between the remote computer and the system host machine by using wi-fi wireless communication; the host machine is used for carrying out high-speed acquisition under the control of programs; the acquired data is uploaded to the computer by the wi-fi network for displaying, storing and analyzing in the remote computer; if the thickness of the oil film of a thrust pad is excessively small or the temperature increase is excessively quick, alarm prompting is carried out to avoid a pad burning accident, thereby ensuring the safe operation of the thrust bearing of the hydro-generator. The data can be used for optimizing the design of the thrust bearing of the hydro-generator, and can be used as the original data of the expert thrust bearing analysis system.

Description

technical field [0001] The invention relates to a dynamic monitoring system for the running state of the thrust bearing of a hydroelectric generator. Background technique [0002] The thrust bearing is called the "heart" of the hydro-generator. It bears the weight of the rotor of the generator set and the axial water thrust. Its working performance and operating state are directly related to the safe and reliable operation of the unit. With the continuous increase of the capacity of hydro-generator units, the requirements for the reliability of large-scale unit operation are also getting higher and higher, and the requirements for safe and reliable operation of thrust bearings are also getting higher and higher. Therefore, during the operation of hydro-generators, monitoring The running state of the thrust bearing is very important. [0003] At present, the method of monitoring the operating state of the thrust bearing of the hydro-generator set is to install a temperature ...
