Pumping sand motor common faults and maintenance explain

In the process of using sand-pulling boats, motor failure often affects production. The main fault phenomena are:

1 pumping sandblasting bearings excessive wear or assembly, resulting in fixed, rotor phase wipe, so that the core surface damage, resulting in sand washers silicon steel sheet short circuit, motor iron Raymond Mill damage increase magnetic separator manufacturer to increase, make the motor Temperature rise is too high. At this time, fine burrs and other tools are used to remove the burrs, eliminate the shorting of the silicon steel sheet, clean it, coat it with insulating paint, and heat and dry it.

2 When the old sand windings are removed from the sand ship, the force is too great, so that the stolen slot is skewed and spread outward. The sand-pulling vessel is then repaired with tools such as needle-nose pliers, wooden hammers, and the like, so that the tooth gaps are reset, and hard insulating materials such as green shell paper and glued wood boards are added between the gap-free silicon steel sheets that are not properly reset.

(3) The surface of the core is rusted due to moisture and other factors. At this point, it needs to be polished with sandpaper, cleaned and painted with insulating paint.

4 High-heat-burned cores or teeth are generated around the group ground. Chisels and other tools can be used to remove the deposits and coat them with insulating paint.

5 The joint between the sand pumping sand core and the base is loose, and the original positioning screw can be tightened. If the sanding boat fails to locate the screw, drill the positioning hole and tap on the base to tighten the set screw.
