Seven steps to sand pump bearing assembly process China Do Pump
China Do Pump is a sand pump, dredge pump, slurry pump manufacturer and designer, now we are showing to dredge pump clients about what are the seven steps to sand pump bearing assembly process.
Sand pump bearing assembly is very critical. This is the rotor part of the sand pump operation. The quality of the bearing and the assembly process are qualified to greatly affect the sand pump performance and energy loss. We should try our utmost and rely on experience to avoid sand pump bearing failure, so as to ensure the use of sand pump and the life of sand pump. Therefore, the assembly and subsequent maintenance of the sand pump bearing is very important. The following is a detailed introduction to the assembly and precautions of sand pump bearings.
Sand pump bearing assembly steps and precautions
I. Sand pump bearing assembly in 7 steps
First, sand pump bearing cleaning
A. Cleaning of processed surface
1. Machined surface of all parts, remove rust marks, check marks, oil stains, etc. and apply engine oil
2. The through holes, blind holes, and screw holes on the mating surface are chamfered with professional tools and corrected with the plane to eliminate iron filings.
B. Cleaning of non-machined surfaces
1.The casting parts of all parts of the bearing assembly are cleared of sticky sand and rust to achieve a smooth surface standard
2. Remove rust, dust and scrub with kerosene in the oil storage room, and paint
Second, sand pump bearing preparation
A. Inventory parts required for bearing assembly
B. Make preparations and make adjustment pads
Third, sand pump bearing assembly, the bearing is sleeved on the shaft
A. Apply oil and clear oil to the modified shaft-mounted bearing
B. Install the grease retaining ring, and press the flange face of the grease retaining ring against the shaft shoulder.
C. The inner ring of the bearing is heated and installed on the shaft and the big end of the inner ring is pressed against the grease retaining ring
Requirements for bearing heating: Use oil or heater to control the temperature below 120 ° C, and place the heated bearing inside the shaft. The inner ring of the bearing should be close to the grease retaining ring, so that the grease retaining ring does not move after the bearing has cooled
Fourth, install the bearing outer ring of the impeller end into the bearing body
A. Apply oil to the cavity at one end of the bearing body
B. Carefully tap the bearing outer ring towards one end of the bearing body until it is slightly lower than the end face of the bearing body
C. Put the bearing end cap with a gasket into the bearing body, and screw on the bearing end cap screws. Tighten the end cap screws evenly. The end cap pushes the bearing outer ring to the correct position.
D. Apply a certain amount of grease in accordance with regulations
E. Grease is manually added to the tapered roller bearing to make the inner ring smooth. In the cavity between the roller and the cage, the remaining grease is scattered between the bearing and the grease retaining ring.
F. Put the threaded end of the shaft into the bearing body, and press the other bearing jacket into the bearing body
G. While slowly turning the shaft, gradually tighten the screws of the bearing end cover until the outer ring of the bearing is correctly pushed onto the inner ring of the bearing
Fifth, adjust the bearing clearance one by one according to the technical standard requirements
Use the adjustment pad to adjust, due to too many parameters are not listed here, if in doubt, please call our company's consultation hotline or email us at any time
Sixth, install maze rings and maze sets
A. Put the labyrinth ring into the groove of the labyrinth ring, assemble two labyrinth rings, apply bearing grease, and arrange the labyrinth ring notches in diameter.
B. Put the labyrinth on the shaft and send people into the end cover until the labyrinth sleeve is against the end face of the bearing inner sleeve.
Seventh, install the imperial nut on the driving end, compact the labyrinth sleeve, and then install the oil cup and wire plug.
