灯泡贯流机组流道检修排水管管径的合理确定

摘要

灯泡贯流机组检修排水时，流道内的水通过排水管自流排入排水廓道，利用积分计算其自流排水时间，从而核算流道检修排水管管径设计是否合理，使之与所选的检修排水泵生产率相适应，达到优化管路及设备的目的%uring the maintenance drainage of bulb-type turbine unit, water in the passage will flow by gravity into the drainage corridor through the drainage pipe. Its gravity drainage duration will be calculated by using integral equation in order to check the design rationality of maintenance drainage pipe in the passage and to make it adapt to the productivity of the selected maintenance drainage pump. Purpose of this checking is to optimize the piping line and equipment
