Different pump start-up characteristics, such as axial pumps,mixed-flow pumps,vortex pumps

axial-flow-pump
Fire pump group start is a light load in terms of prime mover start, under normal circumstances will not start any problem. However, for some large units, due to the inertia of the unit, starting difficult, start a larger start current, pay attention to start the way, then the power grid or motor damage. Therefore, the start-up characteristics of different types of pumps should be taken seriously. 1, the starting characteristics of the vortex pump - open the valve to start Vortex pump in the...
