高速水力测功机修理研究

Research on Repair of High Speed Hydraulic Dynamometer

高速水力测功机是涡轴发动机试车台的重要设备,因长期处于超负荷运转状态,近年来该设备故障频发。文章主要研究高速水力测功机装配技术和零件修复技术,如轴承与轴承座和轴的配合研究,轴承座和轴的修复;在测功机水腔密封环(密封衬套)损磨严重的情况下,密封衬套的修复;轴承润滑密封结构(篦齿和前、后密封衬套)和对应的损坏件修复;测功机装配工艺。本研究旨在通过深入分析,为高速水力测功机的维护提供有益的参考和指导。

The high-speed hydraulic dynamometer is an important equipment for turboshaft engine test benches.Due to longterm overload operation,this equipment has experienced frequent failures in recent years.The article mainly studies the assembly technology and component repair technology of high-speed hydraulic dynamometer,such as the study of the fit between bearings and bearing seats and shafts,and the repair of bearing seats and shafts;In the case of severe wear and tear on the sealing ring(sealing liner)of the water chamber of the dynamometer,repair of the sealing liner;Repair of bearing lubrication and sealing structures(grate teeth and front and rear sealing bushings)and corresponding damaged parts;Dynamometer assembly process.This study aims to provide useful reference and guidance for the maintenance of high-speed hydraulic dynamometer through in-depth analysis.
