Centrifugal pump concentricity measuring device

The invention discloses a centrifugal pump concentricity measuring device, which comprises a clamping base indicator frame, a fixing rod, a radial dial indicator and an axial dial indicator, wherein the clamping base indicator frame is of an integrally-formed structure, and a fixed clamping base is fixed to a first side edge of a coupler of a centrifugal pump; the radial dial indicator is fixed on the fixed clamping base, and a measuring head of the axial dial indicator is in contact with a second side edge of the coupler of the centrifugal pump; and one end of the fixing rod is vertically fixed on a fixed plate; the radial dial indicator is fixed to the other end of the fixing rod, and a measuring head of the radial dial indicator is in contact with a third side edge of the coupler of the centrifugal pump. The centrifugal pump concentricity measuring device adopts the clamping base indicator frame of an integrally-formed structure, fixes the radial dial indicator and the fixing rod on the same indicator frame, effectively avoids the current situation that the existing dial indicator frame has high requirements on a pump coupler and a pump bearing frame structure, reduces indicator installation difficulty of operators, shortens indicator installation time, and increases measurement accuracy.
