Detailed Instructions On How To Adjust The Impeller Clearance

The adjustment of the slurry pump impeller is to ensure the efficient operation of the pump. The following is a detailed explanation on the adjustment of the slurry pump impeller:

In order to ensure the efficient operation of the slurry pump, the gap between the impeller and the front guard plate must be adjusted in time. The gap between the impeller of the metal-lined pump and the front guard plate is between 0.5-1mm, and the gap between the impeller of the rubber-lined pump and the front and rear guard The gaps are equal.

When adjusting the impeller clearance, first stop the pump, loosen the bolts pressing the bearing assembly, tighten the nuts on the adjusting bolts to move the bearing assembly forward, and at the same time rotate the drive shaft by hand in the direction of the pump. Until the impeller rubs against the front guard plate, for metal-lined pumps, loosen the nut just tightened by half a turn, and then tighten the front nut on the adjusting bolt to move the bearing assembly back.

At this time, the gap between the impeller and the front guard plate is between 0.5-1mm. For the rubber-lined pump, the bearing assembly is moved forward by tightening the nut on the adjusting bolt, so that the impeller and the front sheath are in contact, and then the bearing assembly is moved toward Move backward to make the impeller contact the rear sheath, measure the total moving distance of the bearing assembly, take half of this distance as the gap between the impeller and the front and rear sheaths, and adjust the position of the bearing assembly by adjusting the bolts to ensure that the impeller and the front and rear sheaths After adjusting the correct clearance value, before restarting, you must recheck whether the impeller is rotating normally.

Whether the pressing bolts and adjusting bolts of the bearing assembly of the slurry pump are tightened, and then start the pump.

In summary, it is about the adjustment of the slurry pump impeller.
