Title
(EN) SYSTEM AND METHOD FOR MONITORING PUMP LINING WEAR
(FR) SYSTÈME ET PROCÉDÉ POUR LA SURVEILLANCE D'USURE DE CHEMISAGE DE POMPE
Abstract
(EN) 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.
(FR) L'invention porte sur un système pour la surveillance d'usure de chemises de carter de pompe. Le système peut comprendre un capteur d'usure disposé à proximité de la chemise de carter de pompe, de telle sorte que le capteur s'use sensiblement à la même vitesse que le chemisage. Le capteur d'usure peut comprendre une pluralité de boucles de circuit ayant différentes longueurs. Lorsque la chemise de carter de pompe et le capteur s'usent pendant l'utilisation, la pluralité de boucles de circuit sont ramifiées en séquence. Un système de commande contrôle les signaux provenant de la pluralité de boucles de circuit pour développer des informations d'usure de chemise. Ces informations sont employées pour signaler à un utilisateur le moment où un ou plusieurs seuils d'usure prédéterminés sont dépassés. D'autres modes de réalisation sont décrits et revendiqués.
