齿轮泵寿命预测方法及橡胶挤出装置
摘要：
检测齿轮（28）的转数（R）和从齿轮泵（14）挤出的橡胶的排出量（Q），根据检测出的转数（R）及橡胶的排出量（Q），计算齿轮（28）每转一圈从齿轮泵（14）挤出的橡胶的排出量的实测值（T1）与理论值（T）间的排出效率（η＝（T1/T））。根据算出的排出效率（η）来预测齿轮泵（14）的寿命。
摘要（英）：

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 · (= T1/T) that is a ratio of a measured value Tl 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 ·.
