Method of machine condition monitoring
First Claim
1. A method of monitoring a fouling condition of a machine comprising:
- measuring at least one machine parameter;
monitoring the at least one measured machine parameter during operation of a machine;
deducing a change in the fouling condition of the machine when at least one monitored measured machine parameter reaches a limit value,wherein the at least one monitored machine parameter is monitored depending on at least one machine parameter other than the at least one monitored machine parameter in defined operating point ranges of the machine,wherein a change in fouling condition of the machine is deduced when at least one monitored machine parameter within a defined operating point range reaches at least one limit value individual to the operating point range,wherein a currently traversed operating point is used for monitoring the fouling condition of the machine only when the currently traversed operating point has been traversed in the respective operating point range for a defined minimum duration, except that an exiting from the respective operating point range for less than a defined tolerance time is permitted;
determining the machine is in a fouled condition based at least in part on the measured at least one machine parameter; and
conducting failure and damage control operations to the machine based on the determination that the machine is in the fouled condition.

Abstract
A method of machine condition monitoring, wherein at least one measured and/or calculated machine parameter is monitored during the operation of a machine, and wherein a change in the machine condition, particularly a critical operating state of the machine, is deduced when at least one monitored machine parameter reaches a limit value, and wherein at least one monitored machine parameter is monitored depending on at least one other machine parameter in defined operating point ranges of the machine, wherein a change in machine condition is deduced when at least one monitored machine parameter within a defined operating point range reaches at least one limit value individual to the operating point range.
