METHOD OF ESTIMATING LIFE OF GEAR PUMP AND RUBBER EXTRUSION APPARATUS |
| 摘要 |
A method of estimating a life of a gear pump includes detecting the number of rotations of a gear and a discharge amount of rubber being extruded from the gear pump; calculating, based on the number of rotations and the discharge amount of the rubber which are detected, a discharge efficiency η (=T1/T) that is a ratio of a measured value T1 of a discharge amount of the rubber that is extruded from the gear pump per one rotation of the gear to a theoretical value T; and estimating the life of the gear pump based on the calculated discharge efficiency η. |

1. A method of estimating a life of a gear pump having a pair of gears that rotate in a state where the gears mesh with each other, the method comprising:
detecting the number of rotations of the gear and a discharge amount of rubber that is extruded from the gear pump; calculating, based on the number of rotations and the discharge amount of the rubber which are detected, a ratio (T1/T) of a measured value T1 of the discharge amount of the rubber that is extruded from the gear pump per one rotation of the gear to a theoretical value I of the discharge amount of the rubber that is extruded from the gear pump per one rotation of the gear; and estimating the life of the gear pump based on the calculated ratio (T1/T). |
