Centrifugal heavy duty trash pumps machining process

After first time heating treatment, the parts still casting blank parts, must after machining process to achieve the standard measurement. If the size is not accurate, will damage the trash pump or can not install well, or shorten the service life. So this step must need professional inspector to inspect. Only under the reasonable range of the tolerance, can go next step. For trash slurry pump impeller, need pass dynamic balancing and static balancing treatment, to make the overall structure even thereby reducing the occurrence of vibration.
