水轮泵长期潜没在水下工作,运行监视困难,零配件(特别是轴承)损坏率甚高,已成为影响水轮泵发挥效益的重大障碍之一。广西藤县水电局工程师黄齐峰最近研究成功一种“截短叶轮轮毂法”,初步解决了水轮泵运行监视问题,并使单台连续运行期限由过去一千小时左右提高到七千小时以上,一套钢轴承就 Long-term underwater submersible pumps work under water, monitoring difficult operation, spare parts (especially bearings) high rate of damage has become a major obstacle to the effectiveness of hydraulic pump one of the obstacles. Guangxi Qixian Hydropower Engineer Huang Qifeng recent successful study of a “truncated impeller hub method” to initially solve the problem of monitoring the operation of the water pump and a single continuous operation period from the past one thousand hours to more than seven thousand hours, A set of steel bearings on it
