Method of eliminating Crushing Equipment failure
Crushing Equipment equipment is the main equipment for mining, mainly for different sizes of rock crushing, Crushing Equipment equipment mainly jaw Crushing Equipment, counterattack Crushing Equipment, impact Crushing Equipment, twin-roller Crushing Equipment, hammer Crushing Equipment and cone Crushing Equipment. Because of the Crushing Equipment's harsh working environment and high compressive strength, it is necessary for users to master the methods of removing common breakdowns of Crushing Equipments. Here we introduce the methods of removing three common breakdowns of Crushing Equipments.
Crushing Equipment three major faults: bearing fault repair, shaft fault repair, and stator and rotor core fault repair. Next we will analyze the three major troubleshooting points:
First, bearing failure repair wear parts
The rotating shaft is supported by bearings, so it is not only a heavy part of the load, but also easy to wear parts.
When the rolling bearing is short of oil, it can hear the sound of & ldquo; the sound of discontinuous & ldquo; the sound of stalk & rdquo; may be the rupture of the bearing ring. Minor noise will be produced when bearings are mixed with sand and other debris or bearing parts with slight wear.
Inspect after disassembly; first inspect the Crushing Equipment bearing rollers, inside and outside steel ring whether there is damage, rust, scar, etc., and then pinch the inner ring of the bearing with the hand, and make the bearing flattened, the other hand force push the outer rigid ring, if the bearing is good, the outer ring should rotate smoothly, rotation is not obvious.
1, The vibration and clamping phenomena of the steel ring do not retrogress after stopping. Otherwise, the bearing can no longer be used. The left hand holds the outer ring, the right hand holds the inner ring, and pushes it in all directions. If it feels loose when pushing, it is worn out seriously.
2, Repair: The rust spots on the outer surface of the bearing can be erased by sandpaper and then washed in gasoline; or when the bearing has cracks, cracks in the inner and outer rings or excessive wear and tear of the bearing, new bearings should be replaced. When replacing the new bearing, the bearing should be the same as the original one.
Two. Troubleshooting of rotating shaft
1, Journal wear; when the journal wear is small, chromium can be plated on the journal, and then grinding to the required size; wear more, can be surfacing on the journal, and then to the lathe cutting and polishing; if the journal wear is too large, also on the journal turning 2-3 mm, and then turning a set of barrel, while the hot sleeve on the journal, and then turning to the required size Size.
2, Shaft bending; if the shaft of Crushing Equipment bends little, it can be repaired by polishing the shaft neck and slip ring; if the bending exceeds 0.2 mm, the rotating shaft can be placed under the press, pressurized and rectified at the beat bend, and the surface of the corrected shaft can be machined and polished by lathe; if the bending is too large, a new shaft must be replaced.
Three. Troubleshooting for stator and rotor core
Both stator and rotor are made of mutually insulating silicon steel sheets, which are the magnetic circuit parts of motors. The damage and deformation of stator and rotor core are mainly caused by the following aspects.
1, Excessive wear and tear of the Crushing Equipment bearings or poor assembly, resulting in friction between the stator and rotor, resulting in damage to the surface of the iron core, resulting in short circuit between silicon steel sheets, increased iron loss of the motor, resulting in excessive temperature rise of the motor. At this time, the use of fine files and other tools to remove burrs, eliminate short silicon steel sheet, clean up after coating insulation paint, and heating and drying.
2, when the old winding is removed, the force is too large, so that the alveolus is skewed and outward. At this time, sharp mouth clamps, wood hammers and other tools to be dressed, so that the alveolar reset, and in the silicon steel sheet with a gap between the hard insulation materials such as green paper, bakelite board.
3, Corrosion of iron core due to damp and other reasons. At this point, sandpaper is needed to be cleaned and painted.
4, burn the core or tooth parts around the ground. It is possible to remove the deposits with chisel or scraper tools, and use the insulating paint to dry.
5, The loosening of the core and the frame can tighten the original locating screw. If the locating screw fails, the locating hole and the tapping can be re drilled on the machine seat, and the fixing screw can be tightened.
