Dynamic balance testing method for simulating mass of media in pump impeller runner

The invention belongs to the technical field of vane pumps and particularly relates to a dynamic balance testing method for simulating the mass of media in a pump impeller runner. The dynamic balance testing method for simulating the mass of the media in the pump impeller runner comprises the first step of medium adhesion, the second step of cooling and solidification, the third step of taking out of excess materials, the fourth step of modification of unbalance and the fifth step of removal of the simulated media. By means of the dynamic balance testing method for simulating the mass of the media in the pump impeller runner, the technical problems that impeller mass unbalance can still be caused when an impeller subjected to dynamic balance testing in air and modification is in practical use, and pump vibration is aggravated are solved. As for the method, the testing conditions are approximate to actual conditions, the dynamic balance precision of the impeller can be remarkably improved, therefore vibration
