Common Sand Making Machine Faults and Solutions:

1. Excessive load on sand making machine bearings: Check the load. Under correct load conditions, control the load within a reasonable range.

2. External intrusion of torque loads on sand making machine bearings: Improve rust-proof seals to minimize downtime. Improve the surface finish of the mating rolling parts. Dark surfaces show slight wear, microcracks 5-10 mm deep, and small openings occur within a wide range from the surface inward. Improve the seals.

3. Improper lubricant: Use lubricant of appropriate viscosity to improve lubrication. Poor surface finish of the sand making machine bearing mating rolling parts. Foreign matter has entered the lubricant. Select an appropriate lubricant.

4. Inappropriate bearing clearance. The bearing housing is poorly precision-controlled, and the rigidity of the bearing housing is uneven: Check the precision of the shaft and bearing housing. Check the clearance.

5. Check the precision of the sand making machine bearing shaft for rust, corrosion, wear, and indentations. When the inner ring of a ball press bearing rotates under load, rolling fatigue on the outer ring raceway or rolling element surface can cause flaking. This damage, known as seizure, can also lead to minor burns on the sliding surface. The lubricant can also cause poor surface roughness. The stripping lubricant is inappropriate, and improvements to the lubricant and lubrication method are recommended.
