Abstract
A system for monitoring wear of pump casing liners is disclosed. The system may include a wear sensor disposed in proximity to the pump casing liner so that the sensor wears at substantially the same rate as the lining. The wear sensor may include a plurality of circuit loops having different lengths. As the pump casing liner and the sensor wear during use, the plurality of circuit loops are sequentially breached. A control system monitors the signals from the plurality of circuit loops to develop liner wear information. This information is employed to signal a user when one or more predetermined wear thresholds are exceeded. Other embodiments are described and claimed.
Claims20
A system for monitoring pump lining wear, comprising:
- a wear detector comprising a housing portion and a circuit portion;
- the wear detector disposed in a casing of a pump, the pump having a casing liner;
- the housing portion having a nose portion that is made from substantially the same material as the casing liner, the nose portion positioned flush with an inner surface of the casing liner adjacent a screw of the pump;
- the circuit portion disposed in or on the nose portion, the circuit portion having at least one circuit loop electrically coupled to a conductor, the conductor coupled to a controller to enable the controller to determine a thickness of the casing liner.
A wear detector for monitoring pump lining wear, comprising:
- a housing portion and a circuit portion;
- the housing portion having a nose portion positionable flush with an inner surface of a pump casing liner adjacent a screw of a pump;
- the circuit portion disposed in or on the nose portion, the circuit portion having at least one circuit loop electrically coupled to a conductor, the conductor coupled to a controller for providing one or more signals to the controller representative of a thickness of the casing liner.
A method for monitoring pump lining wear, comprising:
- at a controller, determining a thickness of a pump casing liner based on signals received from a conductor associated with a wear detector;
- wherein the wear detector having a nose portion positioned flush with an inner surface of the pump casing liner, the nose portion made from substantially the same material as the pump casing liner, the wear detector having a circuit portion with at least one circuit loop disposed adjacent the nose portion, the at least one circuit loop electrically coupled to the conductor.
