Methods and systems for monitoring a seal assembly
A method for monitoring functionality of a seal assembly within an injector feed assembly is described. The method includes providing a buffer fluid to the seal assembly, measuring at least one of a pressure and a flow rate of the buffer fluid, and determining a functionality of the seal assembly based at least partially on the at least one of a pressure and a flow rate of the buffer fluid.
1. A seal monitoring system for monitoring functionality of at least one seal assembly in an injector feed assembly that includes a first section and a second section, the second section configured for coupling to the first section, wherein the first section and the second section each comprise at least one wall that defines at least one channel, said system comprising:
a buffer fluid supply system for supplying buffer fluid to a seal assembly positioned between the first section and the second section; and
a buffer fluid monitoring system comprising at least one of a pressure monitor configured to monitor a pressure of the buffer fluid or a flow rate monitor configured to monitor a flow rate of the buffer fluid supplied to the seal assembly and to determine a functionality of the seal assembly based at least partially on at least one of the buffer fluid pressure or buffer fluid flow rate.
2. A seal monitoring system in accordance with claim 1 wherein said buffer fluid supply system supplies buffer fluid at a predefined pressure and flow rate.
3. A seal monitoring system in accordance with claim 2 wherein said buffer fluid supply system supplies buffer fluid to the seal assembly at a pressure that is greater than the pressures of either fluid separated by the seal assembly.
4. A seal monitoring system in accordance with claim 1 wherein said buffer fluid supply system further comprises a plurality of seal pressure branches configured to supply buffer fluid flow to the seal assembly.
5. A seal monitoring system in accordance with claim 4 wherein said buffer fluid monitoring system further comprises a plurality of flow rate monitors, each of said plurality of flow rate monitors coupled to one of said plurality of seal pressure branches and configured to measure a range of flow rates.
6. A seal monitoring system in accordance with claim 4 wherein at least two of said plurality of seal pressure branches comprise flow rate monitors configured to measure different flow rate ranges.
7. A seal monitoring system in accordance with claim 1 wherein said buffer fluid monitoring system determines a composition of at least one of the fluid and the buffer fluid and determines a functionality of the seal assembly based at least partially on the composition determination.
