| Abstract: | According to the characteristics of pumping system with long horizontal pipeline,the representation of wavespeed which changes with free air volume in liquid gas mixture uniform flow is researched,and a mathematical model for waterhammer calculation and pump boundary condition with air release and variable wavespeed are presented,and waterhammer due to pump stoppage caused by power failure in long horizontal pipeline is calculated.Moreover,based on the calculation and analysis results,waterhammer protection problems arising in this system are also investigated and solved. |
