虹吸滤池排水管的改进

IMPROVEMENT OF THE DRAINAGE PIPES OF SYPHOMATIC FILTER

作者通过对虹吸滤池矩形排水虹吸管的失效分析,认为失效主要是由较大的弯曲应力及疲劳损伤所引起,而改用的圆形截面管与其相比,具有较高的刚度和强度,可以提高排水虹吸管的寿命和可靠性.

The inefficency of rectangle drainage pipes of syphomatic filter was analysed and it is believed that the originals are the damages caused by excess bending stress and fatigue. To replace rectangle pipes with pipes of circular section having higher stiffness and strength the lifetime and reliability of the drainage pipe of syphomatic filter will be improved.
