How to measure the bending of pump shaft?
When the shaft is bent, it causes the unbalance of the rotor and the wear of the moving parts. The small bearings are placed on the V iron, and the large bearings are placed on the roller support
The difference between two readings indicates the maximum radial runout of the shaft bending, also known as runout. The axial bending is 1/2 of the camber, and the radial runout of the general axis is no more than 0.05mm, and the ends are more than 0.02mm.
V, iron or stent should be placed stably, then dial branch, dry point axis, and then slowly moving wheel shaft, such as bending, each turn micrometer has a maximum and minimum readings,
