1. Explosion-proof motor shall not be disassembled; disassembly and maintenance, can not use the parts of the explosion-proof surface for the pry bar fulcrum, but also not allowed to beat or hit the explosion-proof surface.
2. Remove the motor, you should remove the hood, the fan, and then remove the end cap and the bearing cover plate wrench bolts, and then use round logs or copper rods along the axial impact axis, the end cover and the base apart , Finally remove the rotor. Demolition of parts, explosion-proof surface should be shelved upward, and covered with rubber or cloth liner, fastening bolts, spring pad, etc. Be careful not to lose.
3. Remove the motor, you should first remove the hood, fan, and then use the casing wrench to disassemble the end cap and bearing cap bolts, and then use round logs or copper rods along the axial impact axis, the end cap and the base apart , Finally remove the rotor. Demolition of parts, explosion-proof surface should be shelved upward, and covered with rubber or cloth liner, fastening bolts, spring pad, etc. Be careful not to lose.
4. If the explosion-proof surface damage, you must use lead-tin solder HISnPb58-2, 30% concentration of flux for hydrochloric acid (for steel parts) or 58-60% tin-zinc solder, solder flux of ammonium chloride 30% Zinc 70%, add water 100 ~ 150% of the mixed solution (cast iron) for welding, solder and the combination of parts to be solid, raised part to be polished to achieve the required finish.
5. In order to prevent rust on the explosion-proof surface, apply oil or 204-1 replacement anti-rust oil on the explosion-proof surface.
PTFE coated fiberglass fabric cloth is made by taking high quality imported glass fiber as weaving material. The basic material is weaved specially into senior glass fiber cloth substrate. Then, by unique technology such as full immersion, impregnation, coating the cloth with PTFE, different thickness and width of PTFE cloth is finally produced.
High temperature resistant PTFE fabrics provide non-stick surface under low and high temperature from -100° to +260° F , basic fiberglass fabric is light weight and strong, it has a low coefficient of thermal expansion and relatively high thermal conductivity, PTFE coating turn its surface into a non-stick surface which makes this composite material perfect for hot sealing, heat pressing, mold releasing and stamping.
Features of PTFE coated fiberglass cloth:
1. stable dimension, high intensity, elongation coefficient less 5‰
2. good temperature resistance, 24 hours working temperature -70-260ºC
3. low coefficient of friction and dielectric constant, good insulating ability
4. Non-sticky, easy to clear stains and adhesives on the surface
5. good chemical resistance, it can resist all most of chemical medicines, acids, alkalis, and salt, it is fireproof, lower in aging.
