When adjusting the clearance of the slurry pump impeller, first stop the pump, loosen the bolts that compress the bearing assembly, screw the nuts on the adjusting bolts to move the bearing assembly forward, and at the same time rotate the shaft by hand according to the rotation direction of the pump until the slurry pump impeller rubs against the front guard plate. For the metal lined pump, loosen the nuts just tightened in front by half a circle. Then tighten the nut at the front of the adjusting bolt to move the bearing assembly backward. At this time, the clearance between the impeller and the front guard plate is 0.5-1mm. As for the rubber lined pump, screw the nut on the adjusting bolt to move the bearing assembly of the slurry pump forward first to make the impeller contact the front cover. When the bearing assembly is moved backward to make the impeller contact the rear cover, measure the moving interval of the total slurry pump of the bearing assembly. Take this interval as the clearance between the impeller and the front and rear sheath, and adjust the position of the bearing assembly with the adjusting bolt to ensure the correct clearance between the impeller and the front and rear sheath.
After adjustment, before restarting, it is necessary to check whether the impeller of slurry pump can rotate normally, whether the compression bolt of bearing assembly and adjustment bolt can be tightened, and then start the slurry pump.
Efficient operation of slurry pump can effectively improve the delivery efficiency and consumption. Starting from the details, you can get a big harvest.
