Abstract
PURPOSE: To reduce the vibration of a pump, by arranging on an impeller unbalanced weight equivalent to the average value ΔF=0.1W0.6 of nondimensional dynamic unbalanced force which balances with fluid reaction force generated by rotation of the impeller in a liquid.
CONSTITUTION: Unbalance weight equivalent to the average valve ΔF=0.1W0.6 of nondimensional dynamic unbalanced force which balances with fluid reaction force generated by rotation of an impeller in a liquid is arranged on the impeller of a centrifugal pump including one blade 2 or a bladeless pump. From a practical point of view, exciting force can be reduced remarkably, by arranging a balancer 11 in addition to attaching a balancer 9 to the back side of the main plate 1 of the impeller, or arranging a thick balancer 12 formed similar partially increasing the thickness of the blade 2, as shown in the figure. Otherwise, effect can be also obtained by partially reducing the weight of a balancer used for static balancing.
