FIELD: measurement equipment.SUBSTANCE: device for determination of an axial force acting at an impeller of a submersible impeller pump stage, comprises a body, a shaft, an impeller installed on a shaft, a guide vane and a force sensor. In the body there is a pressing bushing, which is made with the possibility of axial displacement, on the outer surface of which there is a support collar. The axial end of the support collar is pressed to the force sensor installed in the body. The upper end of the pressing bushing represents an axial support of the impeller. In the body there is at least one window in the radial direction.EFFECT: simplified design, higher reliability and accuracy of measurements.5 cl, 3 dwg |
