Abstract
Official abstract text for this publication.
A method of determining wear of a seal element includes rotating a seal plate relative to the seal element and such that the seal plate and the seal element form a rotational sealing interface. The seal element includes an insert embedded in the seal element. A portion of the seal element is worn with a sealing face of the seal plate. The insert is contacted with the sealing face of the seal plate. A portion of the insert is worn to create a wear particle of the insert. The presence of the wear particle in a lubrication oil is sensed with an oil monitoring system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of determining wear of a seal element, the method comprising: rotating a seal plate relative to the seal element, wherein the seal plate and the seal element form a rotational sealing interface, wherein the seal element includes an insert embedded in the seal element; wearing a portion of the seal element with a sealing face of the seal plate; contacting the insert with the sealing face of the seal plate; wearing a portion of the insert to create a wear particle of the insert; and sensing the presence of the wear particle in a lubrication oil with an oil monitoring system. 2. The method of claim 1 , further comprising monitoring a flow of the lubrication oil with the oil monitoring system. 3. The method of claim 2 , further comprising providing notification of the presence of the wear particle in the lubrication oil with the oil monitoring system. 4. The method of claim 1 , wherein sensing the presence of the wear particle in the lubrication oil comprises scanning the lubrication oil with a sensor to detect the presence of objects that are not the lubrication oil. 5. The method of claim 4 , wherein sensing the presence of the wear particle in the lubrication oil comprises scanning the lubrication oil with the sensor to detect the presence of a particle including the same material composition as a material of the insert. 6. The method of claim 5 and further comprising: determining a magnetism of the particle and comparing the magnetism of the particle to a known magnetism of the material of the insert.
