Analyze the Stator and Rotor Damage of Sand Washer

Sand washer is the equipment used for washing artificial sand and natural sand. This mineral sand washer is a highly efficient machine researched by Henan Hongxing Mining Machinery Co., Ltd. by adopting advanced technology and combining with the actual situation of the domestic and foreign sand and stone industry.

Stator and rotor are all mutually insulated by the silicon quartet built, which is part of the motor 's magnetic circuit . Stator and rotor core of damage and deformation is caused mainly by the following reasons.

1. Due to other causes of damp core surface corrosion. At this point required a clean sanding, after cleaning ,coating with insulating paint.

2. Between the iron core and base combinationwith loose, old screw can be tightened. If the screws failure, which can be positioned at the base station re- drill and tap holes, tightening the screws.




3. Around group of earth connection produce high temperature to burn down iron core slot or bad tooth department. Available tools such as chisels or scraper to clean and remove deposited material, coating with insulating paint and drying.

4. Dismounting the old winding of using excessive force ,which can cause pirates of the slot crooked, and splayed out. At this point, the application needle nose pliers, wood hammer and other tools to repair, making tooth socket reset, and in the bad reset the gap in between silicon steel to add green shell paper, wood and other hard rubber insulation materials.

5. Rolling bearing excessive wear or assembly bad, which can cause the stator and the rotor mutual friction, making the iron core surface damage, and then causing a short circuit in between silicon-steel sheet, increasing motor iron loss, making the motor temperature rise too high. When application fine file tools such as removing burr, eliminating silicon steel short sub, after cleaning, voating with insulating paint, heating and drying.
