AI Technical Summary

Technical Problem

During the assembly of centrifugal slurry pumps, especially during initial assembly or reassembly after maintenance, aligning the bolt holes of the side sections with the main housing is difficult and time-consuming because these materials are usually made of wear-resistant materials that are difficult to machine.

Method used

An angular groove is designed on the outer edge of the pump housing assembly. The center line of the groove is at an angle to the radial line extending from the central axis to receive fasteners, thereby simplifying the bolt installation process.

Benefits of technology

By using angled grooves, the bolt installation process is simplified, the need for machining is reduced, assembly efficiency and accuracy are improved, and manufacturing difficulty and time costs are reduced.
