Condition monitoring of pumps and pump system
First Claim
1. A method of monitoring the condition of a pump or a component of a system comprising a pump which component is not a component of the pump, the method comprising the steps of generating a predetermined test condition in said pump or system component and obtaining signals indicative of a condition of said pump or system during a period in which said test condition is present.

Abstract
A method of monitoring the condition of a pump (10) or at least one component of a system that includes a pump which component or components are not a part of the pump, includes the step of generating a pre-determined test condition in the pump or system component or components. During a period in which such a test condition is present, signals indicative of the pump or system component or components are obtained. Wear in the pump bearings, the build-up of deposits in the pump or in pipework forming a part of the pump system can be detected or predicted and corrective action taken before the pump or system fails. By providing a method of monitoring pump or system condition in-situ, it is possible to reduce the likelihood of pump failure in use and the need to carry out over frequent servicing of the pump.

- 31. Apparatus comprising a pump, pump controller and at least one sensing device for sensing a pump operating parameter, said pump controller being able to control said pump so as to selectively generate a predetermined pump test condition and the or each said sensing device providing signals indicating values of said parameter when said test condition is generated.
- 37. Apparatus comprising a pump, a controller, an exhaust conduit extending from said pump, at least one sensing device for sensing a condition in said conduit, a connection associated with said pump and or conduit for connecting said pump and or conduit with a source of pressurised gas and valving for controlling flow of said gas into said pump and/or conduit, said controller being able to control said valving to selectively admit said gas into said pump and/or conduit so as to generate a predetermined test condition in said conduit and the or each said sensor providing signals indicative of said condition in the conduit when said test condition is generated.
