机械密封渣浆泵A宜黄机械密封渣浆泵泵技术纵横
If the cutting heat produced in the cutting process is not high, and the impeller surface layer does not produce thermoplastic deformation, in this case is mainly cold plastic deformation, then the surface layer will produce residual comdivssive stress. When the cutting heat is higher and even the thermoplastic deformation is produced in the surface layer of the slurry pump impeller, then the comdivssive stress caused by the thermal plastic deformation and the cold plastic deformation will offset part of each other, if the cold plastic deformation occupies the dominant position. May play a leading role in one or both of these reasons under certain conditions of course AH slurry pump is mainly from the divvious three aspects of the comdivhensive effect of the results of the slurry pump impeller surface layer after mechanical processing produced a complex residual stress slurry pump impeller surface layer will produce residual tensile stress. In grinding generally due to high grinding heat, often with metallographic deformation and thermal plastic deformation caused by tensile stress, therefore, the surface layer of the slurry pump impeller often with residual tensile stress.

When mediating the impeller clearance, first stop the pump, loosen the bolts of the clamping bearing assembly, twist the nut on the bolt, make the bearing assembly move forward, and rotate the shaft with the hand rotation in the direction of the pump rotation until the impeller is rubbed against the front guard plate. How does the slurry pump impeller mediate? For metal lining pumps, the nut that is just tightened in front is loosened half a lap. The NUT in front of the adjustment bolt is then tightened so that the bearing assembly is moved back, At this time the impeller and the front guard gap in the 0.5-1mm, for the rubber lining pump by twisting the nut on the bolt, so that the bearing assembly first move forward, so that the impeller and the front sheath contact, in order to make the bearing assembly backward, so that the impeller and the rear sheath contact, measure the total moving distance of the bearing assembly, take this distance generally as the gap between the impeller and the front and rear sheath The position of the bearing component to ensure the correct clearance value of the impeller and the front and rear sheath. After adjustment, before starting again, it is necessary to re-check whether the impeller rotation is normal, bearing the formation of comdivssion bolts and adjustment bolts are tightened.
