APPARATUS AND METHOD FOR MONITORING A HYDRAULIC PUMP ON A MATERIAL HANDLING VEHICLE
Wear of a pump is estimated using a process that involves operating the pump to drive a hydraulic actuator that moves a member. The actual speed of the member is determined and the speed of the pump is sensed. Pressure of fluid conveyed from the pump to the hydraulic actuator also is sensed. A predi...

| description | Wear of a pump is estimated using a process that involves operating the pump to drive a hydraulic actuator that moves a member. The actual speed of the member is determined and the speed of the pump is sensed. Pressure of fluid conveyed from the pump to the hydraulic actuator also is sensed. A predicted speed of the member is calculated based on the speed of the pump and the pressure of the fluid. The predicted speed is compared to the actual speed and the result is employed to provide an indication of a degree of wear of the pump. The difference between the predicted speed and the actual speed increases as the pump wear increases.
Lusure dune pompe est estimée au moyen dun procédé qui implique la mise en marche dune pompe pour entraîner un actionneur hydraulique qui déplace un élément. La vitesse réelle de lélément est déterminée et la vitesse de la pompe est détectée. La pression du fluide transmis de la pompe vers lactionneur hydraulique est également détectée. Une vitesse prédite de lélément est calculée daprès la vitesse de la pompe et la pression du fluide. La vitesse prédite est comparée à la vitesse réelle et le résultat sert à fournir une indication dun degré dusure de la pompe. La différence entre la vitesse prédite et la vitesse réelle augmente avec lusure de la pompe. |
