Extreme Transient Flow in Pumping System due to a Tripping Pump Disturbance

Abstract:

Taking a pumping station project with large scale centrifugal pumps as working example, an extreme transient flow in the pumping system caused by tripping pump due to electric supply failure was analyzed, and hydraulic disturbance or impulsion to the rest working running pumps were investigated by using the software of the Deltares WANDA 3.73. The results show that the rest running pumps in the system due to a sudden tripping pump disturbance are heavy disturbed when the tripping pump is suddenly failed from the pumping system. The flow rate and input power for the working pumps are greatly jumped shortly. The strongly transient impulsion to the pumping system is quite significant.
