Bearing cover clearance measurement
Thread Content
How is the bearing gland clearance of a single-stage cantilever centrifugal pump measured? What are the specific steps? I’m a beginner, thank you
The bearing is installed in the bearing housing along with the shaft, pushed forward against the positioning platform or an elastic retainer ring. A depth gauge is used to measure the distance from the end face of the bearing housing to the outer ring of the bearing, and this value is recorded. Then, the distance from the end face of the bearing cover to the shoulder is measured and recorded as well. Based on these values and the thickness of the existing highland barley paper shims, it is determined whether it is necessary to modify the bearing cover
The second floor has been explained in great detail. Be careful not to thicken the gasket. Otherwise, the bearing will generate a lot of heat.
The moderator on the second floor explained it in great detail. However, when taking measurements, it is important to collect several points to check whether the values are consistent; if there are significant differences, it is necessary to verify whether the bearing is properly installed. Finally, decide on the thickness of the green-shell paper or the depth of the pressing.
The end gland of the pump coupling should maintain a gap of 0.10–0.15 mm from the bearing housing. The distance can be measured using a depth gauge by determining the depth of the gland’s step and the distance from the bearing housing to the outer ring of the bearing; the difference between these two values gives the required gap.
