Crushing Equipment major failure phenomenon and exclude

Posted:10-17-2012

Crushing Equipment bearings or excessive wear should be replaced with new bearings. Crushing Equipment bearings replaced with new bearings, you should use the same with the original model.


The motor failure of Crushing Equipment in the course often affect the production, major failure phenomenon:A constant, the Crushing Equipment rotor core troubleshooting Stator and Crushing Equipment rotor quartet built by the mutual insulation of the Crushing Equipment silicon steel sheet is part of the motor's magnetic circuit. Given the Crushing Equipment damage and deformation of the rotor core is mainly caused by the following reasons

1. Crushing Equipment bearing excessive wear or bad assembly, resulting in fixed, the Crushing Equipment rotor rub, so that the Crushing Equipment core surface damage and cause a short circuit, silicon steel plate between the motor iron loss increases, so that the Crushing Equipment motor temperature is too high. Then application of tools such as fine file to remove the Crushing Equipment burr, the elimination of silicon steel short, coated with insulating paint to clean up after, and heating and drying.

2. removal of the old Crushing Equipment winding, excessive force, Pirates of the slot skew and go out there. The Crushing Equipment application of needle nose pliers, wood and a hammer and other tools to be trimmed, teeth bad reset, and joined Shell Green Paper, plastic, wood and rigid insulating material between the Crushing Equipment gap of silicon steel sheet to have a bad reset.

3. due to moisture and other reasons caused by the Crushing Equipment core surface corrosion. At this point need to use sandpaper to clean, clean up and coated with insulating paint.

Crushing Equipment bearing Troubleshooting Shaft rotation, is the heaviest part of the load bearing support, and easy-to-wear parts.

1.The Crushing Equipment operation of inspection;When the Crushing Equipment rolling bearing short of oil, will to hear Gulugulu sound; if to hear the Crushing Equipment sound of the discontinuous Terrier, possibly Crushing Equipment bearing steel ring rupture. Crushing Equipment bearing mixed with sand and other debris with mild wear or bearing parts, will produce a slight noise.After the Crushing Equipment demolition of inspection;Look at the Crushing Equipment bearing rollers, inside and outside steel ring is damaged, corroded, scarring, and then hand pinch the bearing inner ring and bearing to settle the other hand, just by pushing the outside circle, if the Crushing Equipment bearing is good, the outer rims should smooth rotation, and rotation without vibration and obvious catching stall outside the rims there is no backsliding. Otherwise, the Crushing Equipment bearings can not be reused. Stuck outer left hand, right hand pinch the rim, hard driven in all directions, promote to feel very loose, badly worn.

2.Crushing Equipment fault repair:Crushing Equipment bearing outer surface of the rust spots available 00 sandpaper erase, and then into the gasoline cleaning; Crushing Equipment bearing cracks, fragmentation of the inner and outer rings, Crushing Equipment bearings or excessive wear should be replaced with new bearings. Crushing Equipment bearings replaced with new bearings, you should use the same with the original model.
