Embodiment 1

[0052] Such as Figure 5-6 As shown, the present invention provides a device for online monitoring of oil film temperature of a composite material thrust bearing, comprising a composite material thrust bearing and an on-line monitoring oil film temperature assembly, the composite material thrust bearing mainly consists of a shoe base 1 and a composite material arranged on the shoe base 1 The material tile surface 2 is composed of; the composite material thrust bearing is provided with a tapered stepped installation hole 5 for installing the online monitoring oil film temperature component, the installation hole 5 runs through the tile base 1 and the composite material tile surface 2, and the installation hole 5 axis It is perpendicular to the composite material tile surface 2 and is set at the highest oil film temperature of the composite thrust bearing. The highest oil film temperature of the composite thrust bearing is determined according to the calculation results of the fi...

Embodiment 2

[0058] On the basis of Embodiment 1, the present invention also provides a method for online monitoring of the oil film temperature of a composite thrust bearing, comprising the following steps:

[0059] S1. Set the sensor heat insulation sleeve 4 outside the probe 31 of the oil film temperature sensor 3;

[0060] S2. Evenly apply a sufficient amount of oxygen-resistant sealant on the threaded section 33 of the oil film temperature sensor 3 to ensure that it is completely filled in the tiny gap between the external thread of the threaded section 33 and the internal thread of the threaded hole 52;

[0061] S3. Before the oxygen-resistant sealant is solidified, screw the online monitoring oil film temperature component into the threaded hole 52 of the installation hole 5, the thread is locked, and the sealant solidifies into a tough solid to prevent the thread from moving, so that the component is firmly fixed on the bearing Inside; when installing, ensure that the flange end fa...

Embodiment 3

[0065] Using the composite material thrust bearing and the composite material thrust bearing oil film temperature detection component, the on-line monitoring of the oil film temperature is implemented on the test unit simulating the working condition of the hydroelectric unit. The process is as follows:

[0066] S1. Place 4 sets of sensor heat insulation sleeves outside the probe 31 of the PT100 temperature sensor;

[0067] S2. Evenly apply a sufficient amount of oxygen-resistant sealant on the threaded section 33 of the temperature sensor to ensure that it is completely filled in the tiny gap between the external thread of the threaded section 33 and the internal thread of the threaded hole 52;

[0068] S3. Before the oxygen-resistant sealant is solidified, screw the online monitoring oil film temperature assembly into the bearing installation hole 5, that is, screw the threaded section 33 of the oil film temperature sensor 3 into the thread of the installation hole 5 through ...

Abstract

The invention provides an apparatus and method for composite material thrust bearing online monitoring oil film temperature, including a composite material thrust bearing and an online monitoring oilfilm temperature component. The composite material thrust bearing mainly includes a bush base and a composite material bush surface disposed on the bush base. A tapered ladder-shaped mounting hole used to mount the online monitoring oil film temperature component is disposed on the composite material thrust bearing. The mounting hole penetrates the bush base and the composite material bush surface, and an axis of the mounting hole is perpendicular to the composite material bush surface, and is disposed at a highest temperature position of an oil film of the composite material thrust bearing. AU-shaped drain groove is disposed on the composite material bush surface. The online monitoring oil film temperature component includes an oil film temperature sensor and a sensor heat insulation sleeve that is sleeved outside an oil film temperature sensor probe. The invention can accurately online monitor the highest oil film temperature of the composite material thrust bearing bush surface, determine a running status of the bearing, and overcome a problem in the prior art that a bush body temperature measurement error is large, leading to an alarm lag, and an accident is easily caused.

Description

technical field [0001] The invention relates to the technical field of bearing oil film temperature measurement, in particular to a device and method for online monitoring of oil film temperature of a composite material thrust bearing. Background technique [0002] Composite thrust bearings have many advantages such as high specific strength, good fatigue resistance, good wear reduction and wear resistance, and can replace traditional Babbitt bearings in hydropower equipment, mill gearboxes, metallurgical equipment, military and other fields. application. When the bearing is running, if the oil film temperature is too high, the viscosity of the lubricating oil will decrease, which will affect the establishment of a sufficient thickness of the pressure oil film of the bearing. If it cannot be controlled in time, it will also lead to the occurrence of tile burning accidents. Therefore, real-time monitoring of the oil film temperature of composite thrust bearings It is an impo...
