1, explosion-proof motor can not be disassembled; disassembly and maintenance, can not use parts of the explosion-proof surface for the pry bar fulcrum, but not allowed to beat or impact explosion-proof surface.
2, the demolition of the motor, you should first remove the windshield, fan, and then remove the cover with the cover and the bearing cap of the bolt, and then, with a round bar or copper rods along the axial impact of the shaft extension, , Finally remove the rotor. Remove the parts, the explosion-proof surface should be set aside and covered with a rubber or cloth liner, fastening bolts, spring mats, etc. Do not lose.
3, dipping and assembly, the explosion-proof surface should be attached to the insulating paint or dirt clean, not with iron and other hard objects scratched, but you can use linoleum grinding uneven place.
4, if the explosion-proof surface damage, must use lead solder solder HISnPb58-2, the flux of 30% concentration of hydrochloric acid (for steel parts) or tin containing 58 ~ 60% tin-zinc solder, the flux of ammonium chloride 30% 70% of zinc, add water 100 ~ 150% mixed solution (on the cast iron) for welding, solder and parts of the combination should be strong, convex parts to be flat, to achieve the required finish.
