矿山救灾超高参数排水泵系统水力过渡过程研究

Study on hydraulic transients in super-high parameters drainage pump system for disaster relief in mine

根据超高参数排水泵系统可以有效解决突发性强、频率高的矿山突水灾害排水问题,建立了救灾超高参数排水泵系统水力过渡过程的数学模型;采用泵站水锤计算的特征线法,建立了多泵机组事故停泵泵端的边界条件,提出了计算方法;并采用FORTRAN语言编制水力过渡过程数值分析计算程序。最后结合实例,验证了数学模型和编制的程序,为实际系统的设计和运行提供理论支持,以保证系统稳定安全运行,提高矿山救灾排水的可靠性。

As the super-high parameters drainage pump system can effectively applies to drainage during suddenly and frequently occurred water-bursting in mine, the paper establishes a mathematics model for studying hydraulic transients in super-high parameters drainage pump system for disaster relief It also uses characteristic line method of calculating the water hammer of pumping station to establish the boundary conditions of broken-down pump in pumping system and offeres calculation method, as well as develops the program used for numerical analysis and calculation of hydraulic transients with FORTRAN. In addition, an example simulation is conducted to validate the above model and the program. The results can offer theoretical reference for design and operation of real system, so as to guarantee the system stable and safe operation and increase the drainage reliability during disaster relief in mine.
