Axial load measuring device for vertical single-stage direct connection centrifugal pump

The utility model relates to an axial load measuring device for a vertical single-stage direct connection centrifugal pump, which is used for measuring the axial load of the vertical single-stage direct connection centrifugal pump and comprises a pump body, an impeller, a pump cover, a motor, a motor shaft, a motor end cover, a cylindrical roller bearing and an axial load measuring device. The impeller is mounted on a motor shaft; and the axial load measuring device is arranged on the motor end cover. When the vertical single-stage direct-connection centrifugal pump works, the centrifugal pumpworks; the axial load of the motor shaft is transmitted to the bearing part through angular contact ball bearings, namely axial load transmission bearings, which are arranged back to back; as the upper end of the push-pull force sensor is fixed with the bracket and the lower end of the push-pull force sensor is fixed with the bearing body part, the axial load borne by the bearing body part can bedirectly transmitted to t
