Assembly of Bearing Components for Foam Slurry Pumps – Assembly Precautions

Foam slurry pumps are used to convey liquids with foam and belong to the vertical slurry pump category. The assembly of bearing components for foam slurry pumps requires attention to certain details.

When assembling the bearings, it is necessary to preheat the inner ring of the bearing, but the temperature should be controlled below 120 degrees Celsius. The inner ring of the bearing must be pressed against the shoulder sleeve. The lower bearing adopts double-row tapered roller bearings, which consist of inner and outer rings, positioning sleeves, and other components. When installing the lower bearing cover, attention must be paid to ensure that the lip surface inside the groove of the lower cover faces outward, and the oil sling ring should be positioned according to the assembly drawing. When installing the labyrinth seal, attention should be given to the staggered positioning of the openings. The axial clearance of the bearing has been ensured by the bearing itself, so there is no need to adjust the clearance during the assembly of the bearing components. However, after the assembly is complete, it is still necessary to check the axial clearance of the installed bearings.

Assembly of Bearing Components for Foam Slurry Pumps – Assembly Precautions

Foam slurry pumps are used to convey liquids with foam and belong to the category of vertical slurry pumps, with a similar frame structure as SP slurry pumps. What should we pay attention to when assembling the bearing components of foam slurry pumps?

When assembling the bearings, it is necessary to preheat the inner race of the bearing, but the temperature should be controlled within 120 degrees Celsius. The inner race of the bearing must be tightly fitted against the shoulder sleeve. The lower bearing adopts double-row tapered roller bearings, which consist of inner race, outer race, positioning sleeve, and other components. When installing the lower bearing housing, attention must be paid to ensure that the lip surface inside the housing groove faces outward, and the oil slinger must be positioned according to the assembly drawing. When installing the labyrinth seal, attention should be given to stagger the openings. The axial clearance of the bearing has already been ensured by the bearing itself, so there is no need to adjust the clearance during the assembly of the bearing components. However, after the assembly is complete, it is still necessary to check the installed axial clearance of the bearings.
