How to solve the problem of sand making machine in sand production line
The importance of the in the sand production line is self-evident. It plays an important role. When the sand making line is in progress, the sand making machine has problems, just like people lose in the normal life. Oxygen, life can not continue, and the sand production line is also the same, so there are problems with the sand making machine, we have to be calm, look for professionals to view and repair, the following Shanghai ZENITH introduces several frequently occurring problems and solutions.
1. The bearing load of the sand making machine is too large: check the load. Under the correct load conditions, control is within a reasonable range.
2, the sand machine bearing torque load of the enemy invasion, inflow: improved rust seals, downtime. Improved surface finish for paired rolling parts. The dark side is shown, the dark surface has a slight abrasion depth of 5-10M micro-cracks and the small opening fractures are installed from the surface inward over a wide range. Improved sealing device.
3. Improper lubricant: Use a lubricant of appropriate viscosity to improve lubrication. The surface finish of the sanding machine bearing paired rolling parts is poor. Foreign matter enters the lubricant. Choose the right lubricant.
4. The bearing clearance is not suitable. The bearing housing is of poor precision and the rigidity of the bearing housing is uneven: check the accuracy of the shaft and bearing housing. Check the gap.
5, bearing shaft rust, erosion, wear and indentation points check the accuracy of the shaft and housing. The inner ring of the ball bearing load of the ball press rotates, and the rolling fatigue of the raceway surface of the outer ring or the rolling surface is flaky. The so-called card injury produces a slight burn on the sliding surface that summarizes the damage caused by surface damage. The surface roughness caused by the lubricating oil is poor. Stripping the lubricant is not appropriate, improving the lubricant and lubrication methods.
