Test Results Of Transition Process Of Pump Shutdown Download Figure 5 a is a schematic diagram of the test bench for the model of the vertical axial flow pump, and figure 5 b is a photograph of the physical model. the nominal diameter of the impeller in the. In this study, a comparative analysis of the shutdown transitions of a full flow pump and an axial flow pump was carried out through numerical simulation and model tests. the udf method was used to achieve control of the impeller rotational speed during shutdown. the results show that during the shutdown transition, the rate of decline of rotational speed, flow rate, and torque of the axial. Finally, one of the best ways to minimize the pressure and power stresses during startup and shutdown is to install a vfd, which has many additional benefits [see ww, march 2008]. variable frequency speed drives eliminate the inrush current and pressure spikes on startup. soft starting reduces the stress on the motor, pump, coupling and the. The operating principle of the pump is to convert mechanical energy to pressure. in operation, a rotating impeller accelerates a liquid and as the area of the pump casing expands the velocity of the fluid is converted to pressure. as a result pressurized fluid exits the pump discharge.
