Key Points For Fault Maintenance Of South Africa Quarry Crusher
Three major faults of the South Africa Quarry Crusher: the maintenance of the bearing fault, the repairing and fixing of the rotating shaft, and the maintenance of the fault of the rotor iron core. Below we analyze the main points of the breakdown maintenance of the South Africa Quarry Crusher:
Wear Parts Of Bearing Fault Repair
Rotating shaft with bearing support is the heaviest part of the load, and it is also easy to wear.
In the operation of inspection; rolling bearing oil, will hear "rolling" sound; if you hear the discontinuous "Geng Geng" sound, may be bearing steel ring rupture. When the bearings are mixed with sand and other sundries or bearing parts with mild wear, a slight noise will be produced.
After the demolition inspection; a first South Africa Quarry Crusher roller bearing, inner and outer rims are broken, rust, scar, and then hand pinch the bearing inner ring and the bearing, right, on the other hand push outside just circle, if the bearing outer ring should be good, smooth rotation, no vibration and obvious stagnation the phenomenon of rotation, stop after the rims no backsliding. Otherwise, the bearing can not be reused. The left hand is stuck in the outer ring, and the right hand holds the inner steel ring, pushing forward in all directions. If it is very loose, it is serious wear.
The rust on the outer surface of the available sandpaper erase bearing, then put into gasoline cleaning; or bearing crack, inner and outer rings of fragmentation or bearing excessive wear, should be replaced with new bearings. When a new bearing is replaced, a bearing that is the same as the original model should be selected.
Troubleshooting Of Rotating Shaft
The shaft neck wear; shaft neck wear is small, can be coated with a layer of chromium in the shaft neck, then grinding to required size; wear more, can be deposited in the shaft neck, and then to the lathe cutting polishing; if the shaft neck wear is too large, also in the Journal on the cut 2-3mm, then a car the sleeve is sheathed on the shaft, while it is hot on the neck, then turning to the desired size.
If the broken shaft shaft bending; bending is small, can be repaired by method of grinding axis neck, bending; if more than 0.2mm, can be placed on the rotating shaft press, in the film bend pressure correction, after correction of the shaft surface polishing lathe cutting; if the bending is too large, you need to change to the new axis.
Troubleshooting Of Stator And Rotor Core
- The stator and rotor are made up of silicon steel sheets which are insulated from each other. It is the magnetic circuit part of the motor. The damage and deformation of the stator and rotor core are mainly caused by the following reasons.
- The excessive wear or improper assembly of the South Africa Quarry Crusher bearing results in the damage of the stator core and rotor surface, resulting in the damage of the core surface, resulting in short circuit between the silicon steel sheets, the increase of motor iron loss and the high temperature rise of the motor. At this time the use of thin files and other tools to remove burrs, eliminate silicon steel sheet short connection, clean up after the coating of insulating paint, and heat drying.
- When the old windings are dismantled, it is too strong to make the alveolus skew and open outward. The application of pliers, Mu Lang first tools to be repaired, the cogging reduction, and green shell paper, plywood and other hard insulating material is added in the silicon steel sheet is not good there is a gap between the reset.
- Corrosion of the core surface caused by damp and so on. At this point, the sand paper needs to be grinded clean, after cleaning and coated with insulating paint.
- The grounding of heat generated in the iron core groove or burned tooth. Use the tools such as chisel or scraper to remove the product and dry it with an insulating varnish.
- The combination of the core and the seat is loosened, and the original positioning screw can be tightened. If the positioning screw is invalid, the positioning hole can be drilled and tapped on the machine seat, and the positioning screw is tightened.
