Bearing block for water supply pump station and repairing technology

Abstract

The invention relates to a bearing block for a water supply pump station and a repairing technology. The bearing block for the water supply pump station comprises a base, a first bearing hole plate and a second bearing hole plate, wherein the first bearing hole plate and the second bearing hole plate are arranged on the base, and holes are coaxial; the lower surface datum of the base is A; the datum of hole axes of the first bearing hole plate and the second bearing hole plate is D; the datum of the outer side surface of a hole of the first bearing hole plate is B; the datum of the outer side surface of the hole of the second bearing hole plate is C; the datum D is parallel to the datum A; the datum B and the datum C are perpendicular to the datum D. The bearing block for the water supply pump station is reasonable in design, compact in structure, and convenient to use.

Description

technical field [0001] The invention relates to a bearing seat for a water supply pump station and a repairing process. Background technique [0002] At present, the water supply pump station is a key component of the municipal water supply pipeline, and its quality directly affects the problems of the urban water supply system, and the most vulnerable component is the bearing, and a key factor affecting the life of the bearing is the processing of the bearing seat Accuracy, especially the coaxiality of the bearing bore; [0003] Since the bearing hole is formed by one-time processing, when the bearing hole is processed by a normal horizontal boring machine, the most influential factor is the flatness of the foot surface. If the flatness of the foot surface is out of tolerance, it will directly cause the bearing hole to be out of alignment during installation. As a result, the bearing is eccentrically worn, the force is uneven, and the damage to the spindle is accelerated. ...

AI Technical Summary

Problems solved by technology

[0003] Since the bearing hole is formed by one-time processing, when the bearing hole is processed by a normal horizontal boring machine, the most influential factor is the flatness of the foot surface. If the flatness of the foot surface is out of tolerance, it will directly lead to the misalignment of the bearing hole during installation. As a result, the bearing is eccentrically worn, the force is uneven, and the spindle is damaged at an accelerated rate.

[0004] For this reason, if the flatness of the bottom surface of the processed bearing seat is out of tolerance, the entire workpiece will be scrapped. The existing repair method is to reprocess the bottom surface, then expand and bore the bearing hole, and then brush plating or inserting the sleeve. The repair process Complicated, not suitable for batch repair, and the repaired holes are easy to wear and have a short service life
