在大型泵站中采用拍门断流,拍门在停机下落时,其运动过程的计算是相当复杂的。本诺模计算图是在研究拍门下落运动方程并编制拍门优化下落电算程序基础上,为将其计算简化而研制的。使用本诺模图进行拍门设计,不仅可使拍门设计简捷化,而且可以迅速地提供多种方案以资优选。 In the large-scale pumping station, the use of a flap-shut-off is adopted. When the flap-gate is dropped, the calculation of the motion process is quite complicated. The Benno model calculation map was developed for the purpose of simplifying the calculation based on the study of the falling door movement equation and the preparation of the falling door optimization and falling calculation program. The use of Benno’s die pattern for door-to-door design can not only simplify the design of the beat gate, but also quickly provide a variety of options for optimization.
