Reverse rotational speed of pumps (Hammer connect edition update 2)

Is there any way of analysing the reverse rotational speed of a pump impeller if slow closing check valves are being used at pump discharge and non reverse ratchet is not being used? I am primarily trying to analyse if the impeller and shaft reaches the critical speed during reverse rotation.

  • I concur with Yashodhan - enter a number in the "report period" field of the pump (1 = report at every timestep), re-compute, then look at the speed graph in the Extended Node Data tab of the Transient Results Viewer.
