Description

Technical Field

[0001] The utility model relates to the technical field of water pump balancing disc detection equipment, in particular to a clamping structure for factory detection of a water pump balancing disc. Background Art

[0002] The balance disc of the water pump is an important balancing device in the multi-stage centrifugal pump. It consists of a balance disc mounted on the shaft and a balance ring fixed on the pump body. During factory inspection, the working surfaces of the balance disc and the balance ring are key parts. It is necessary to ensure that there is no skew or unevenness between the two working surfaces to avoid a large amount of leakage during the operation of the pump, which affects the pressure required to maintain the balanced axial thrust in the balance chamber. During factory inspection, a series of measurements of the balance disc are also required, including the end face circular runout of the working surface of the balance disc and the radial circular runout of the balance disc hub. Before testing the balance disc of the water pump, the balance disc of the water pump is generally clamped and fixed using a clamping device, but the existing clamping device can only clamp and fix the balance disc of the water pump at one position from both sides, and the clamping effect is poor, which can easily cause the balance disc of the water pump to move during testing or measurement, affecting the accuracy of the test results.
