Motor repair

Explosion-proof motor, do not disassemble; delete access, you can not use explosion-proof surface portion as a fulcrum to pry bar, but not allowed to beat or hit the surface explosion.Remove the Vibrator Motors, you should remove the fan cover, fan, tube clamp, then remove the cap and bearing cap bolts, and then, with the log or the impact of copper along the axial axis, cover and base separation, and finally remove the rotor. Removal of parts, explosion-proof surface should hold up, and covered with rubber or cloth pad, fastening bolts, spring pads, etc., be careful not to lose.

Impregnation and assembly, the insulation should be attached to the face of explosion-proof paint or dirt, clean, Electric Motor do not use metal plates and other hard objects to scratch, but you can not flat oil stone polished place.
If the explosion-proof surface damage, we have to use tin-lead HISnPb58-2,30% concentration of hydrochloric acid flux (steel components), or 60% tin 58 Sn-Zn solder, 30% ammonium chloride flux, zinc chloride 70%, 150% water mixed solution (cast iron) 100 welding, welding and parts of the proposed combination of a solid, part of the ground, the required completion.
In order to prevent surface rust-proof, explosion-proof coated with oil or replacement-type anti-rust oil.If the actual operating current than the motor nameplate current rating marked on the lower 70%. Indicates that the motor power of the election too large (ie, the "big horse-drawn cart," a smaller motor power should be reversed if the measured operating current than the Electric Motor nameplate current rating marked on the large 40%. Indicates that the motor power selected too small (ie, "small horse-drawn carts"), a larger motor power should be reversed.
