The process of installing the bearing parts of the slurry pump can be roughly divided into 7 parts.
The first is the clean-up work.
a.Cleaning of the machined surface.
1.On top of the machined surface of all parts, remove rust marks, inspection marks, grease, etc., and apply engine oil.
2.Use professional tools to chamfer through-holes, blind holes, and screw holes on the mating surface, and correct them along the plane to eliminate iron filings.
b.Cleaning of raw surfaces.
1.Remove sand and rust from the cast parts of all parts of the bearing assembly to obtain a smooth surface.
2.Rust and dust from the degreasing chamber, scrub clean with kerosene, paint.
2. Preparations.
a.Inventory the parts required for bearing assembly installation.
b.Do your homework and make the adjustment pad.
Third, the bearing is assembled, and the inner sleeve of the bearing is installed on the shaft.
a.Apply engine oil and cleaning oil to the corrected shaft bearings.
b.Install the grease ring and press the flange face of the grease ring against the shoulder.
c.The inner ring of the bearing is heated and mounted on the shaft, and the large end of the inner ring is used to hold the grease retaining ring.
Requirements when heating bearings: Use oil or heater to control the temperature below 120°C. The heated bearing is sleeved into the shaft. The inner ring of the bearing should fit snugly against the grease ring until the grease ring does not move after the bearing has cooled.
4. Install the outer ring of the bearing at the impeller end into the bearing body.
a.Apply engine oil to the cavity at one end of the bearing body.
b.Carefully tap the outer ring of the bearing body to one end until it is slightly below the end face of the bearing body.
c.Install the bearing end cap and gasket into the bearing body and screw the bearing end cap screw. Tighten the end cap screws evenly, and the end cap pushes the outer ring of the bearing to the correct position.
d.Apply a certain amount of grease as prescribed.
e.Grease is manually added to the tapered roller bearings to smooth the cavity between the inner ring, rollers and cage, and the remaining grease is distributed between the bearing and the grease retaining ring.
f.The threaded end of the shaft is fitted into the bearing body and the other bearing sleeve is pressed into the bearing body.
g.While slowly rotating the shaft, gradually tighten the screws of the bearing end cap until the outer ring of the bearing is properly pushed over the inner ring of the bearing.
Fifth, adjust the gaps one by one according to technical standards.
Use the adjustment pad to make adjustments. Since there are so many parameters, I won't list them all here. If you have any questions, you can call our company's consultation** or **QQ at any time for consultation.
Sixth, install the maze ring and maze set.
a.Insert the labyrinth rings into the labyrinth ring groove, install two labyrinth rings, apply bearing grease, and arrange the labyrinth rings relative to the diameter.
b.Place the labyrinth sleeve on the shaft and push it into the end cap until the labyrinth sleeve is pressed against the end face of the inner sleeve of the bearing.
Seventh, install the inch nut on the drive end, tighten the labyrinth sleeve, and then install the oil cup and plug.
