Abstract

Pump stations for irrigation and drainage are important structures that handle water for an area as well as farmlands. Many pump facilities must be periodically rebuilt. However, information to evaluate the deterioration progress is presently lacking for pump facilities. In this study, we carried out a questionnaire survey on the maintenance of pump facilities to determine the actual situations and problems.<br>As a result, we confirmed that the main causes of trouble of the bearing characterizing the deterioration depended on wear that occurred with increase of the operation time. In addition, we showed the appropriate timing for evaluation and repair can be determined by quantitatively diagnosing the deterioration of parts. Therefore, we propose the application of condition based maintenance about pump facilities is important to prevent the progression of deterioration.
