1. explosion-proof motor shall not disassemble; disassembly and maintenance, cannot use parts of the explosion-proof surface as lever fulcrum, but does not allow to strike or hit the explosion-proof surface.
2.when disassembling the motor should be preferential wind cover, fan, and then the casing plate hand removal of end cap and a bearing cap bolt, then with logs or copper rod along the axial impact shaft extension, the end cover and the base are separated, and finally removed rotor. Remove parts, explosion-proof surface should be put on hold, and use a rubber or cloth pad cover, fastening bolts, spring pad and other attention not to lose.
3.dipping paint and assembly, should will explosion-proof surface attached to the insulation paint or dirt clean, not with iron hard scratching, but can with an oilstone grinding uneven.
4. if the flameproof surface damaged must be with tin lead solder HISnPb58-2 flux concentration of 30% hydrochloric acid (for steel parts) or containing tin zinc solder tin 58~60% and flux for 30% of ammonium chloride and zinc chloride 70%, water 100~150% mixed solution of iron welding, solder and parts of the combination to firmly, bulge to smooth, set to reach the finish. 5, in order to prevent the explosion-proof surface rust, should be in the explosion-proof surface of oil or 204-1 replacement type of rust proof oil.
