Analysis of booster pump diaphragm coupling fatigue failure

Abstract

Abstract:

Abstract:This paper introduced the structure and working principle of diaphragm coupling,analyzed diaphragm stress distribution,fracture hazard area. After analyzing the reasons caused Huadian Jiangsu Energy Company Limited Jurong Power Plant’s booster pump diaphragm couplingfatigue failure.The author indicated that the center deviation is the main reason,and provided a serious of measures,such as to
accomplish diaphragm coupling cold state center checking and adjustment,enhance inspection and etc.Safety of unit operation was ensured.
