The utility model belongs to the technical field of artificial heart, specifically speaking is blood pump suspension impeller axial displacement dynamic measuring device, and the the device measurablequantity is because of the suspension impeller axial displacement change value that leads to of stable rotation not. Blood pump suspension impeller axial displacement dynamic measuring device includes blood pump operating mode control unit and displacement measurement unit. Blood pump operating mode control unit adjusts the specific state of awaiting measuring according to the experiment parameter with the blood pump. Displacement measurement unit accessible magnetism gauge stand adjustment displacement sensor visits head position and puts, the axial displacement of blood pump impeller undertransparent organic glass window through pump case on the blood pump and the specific operating mode of the measurement of the glycerol liquor solution in the pump case to the displacement curve thatshows the impeller on the d
