当泵进行动平衡时，雷竞技官网最新版整个转子部件应制作在一起。更换了叶轮，平衡点也改变了。它需要重新调整。如果是普通的单级泵，由于其残余不平衡，就不需要了。雷竞技官网最新版它对泵的影响很小。雷竞技官网最新版如果是高速泵或多级泵，则需要重新平衡。雷竞技官网最新版对于多级泵，转子部件要小，动平衡雷竞技官网最新版后，标记好各部件的位置，再将整个泵组装成一个整体，这样才能达到动平衡的效果。

　　 The conditions for the dynamic balance of the water pump rotor: high-speed pumps need to be tested for dynamic balance, and low-speed general pumps can only be statically balanced.

　　 If a rigid rotor cannot meet the conditions of a statically balanced disc rotor, two planes need to be balanced, that is, dynamic balance. The rotor conditions for static balance only are as follows (balance static G0.4 is the highest accuracy, in general, the dynamic balance static of the pump impeller selects G6.3 or G2.5):

　　 1. For the rotors of single-stage and two-stage pumps, when the working speed is ≥1800 rpm, as long as D/b<6, the dynamic balance should be done;

　　 2. For multi-stage pumps and combined rotors (level 3 or above), regardless of the working speed, the combined rotor should be dynamically balanced;

　　 3. General single-stage centrifugal pumps do not need to be used;

　　 4. A large single-stage pump (3000m3 circulating water pump) needs to be done;

　　 5. It is best to do a multi-stage pump;

　　6. It is best to do a high-speed pump;

　　 7. the impeller of the regular pump manufacturer has been statically balanced before leaving the factory.

一般情况下，单级泵在更换叶轮后不需要再次进行动平雷竞技官网最新版衡试验，但应确保更换的叶轮零件已经进行过动平衡试验(如用户在动平衡试验后切割叶轮直径，则需要再次进行动平衡试验)，对于多级离心泵，如果更换叶轮，即使叶轮已经进行过动平衡试验，在更换叶轮时，将叶轮安装在泵轴上，整个转子需要再次进行动平衡试验，记住雷竞技官网最新版各部件的位置，然后拆下并按下叶轮动平衡试验的位置，重新安装泵。
