Explosion-proof motors can be divided into explosion-proof type, increased safety type, "n" type, positive pressure shell type and dust shell protection type according to the explosion-proof type. These five kinds of explosion-proof motors can be said to have similar test standards before the production license is issued. The following are Jiangsu Gaoke's introduction to the inspection items and standards for various types of explosion-proof motors.

1. Explosion-proof three-phase asynchronous motor inspection items include: structural inspection, impact resistance test, temperature measurement, insulation sleeve torsion test, outer shell pressure test, internal ignition non-transmission test, lead-in device sealing test and mechanical strength Experimentation, determination of efficiency.

2. Increased safety explosion-proof motor inspection items include: structural inspection, impact resistance test, temperature measurement, tE time measurement, starting current ratio, clamping test of the lead-in device, insulation dielectric strength test, and determination of efficiency.

3. "n" type explosion-proof motor inspection items include: structural inspection, impact resistance test, temperature measurement, clamping test of lead-in device, insulation dielectric strength test, determination of efficiency.

4. Inspection items of positive pressure shell type explosion-proof motors include: structural inspection, impact resistance test, temperature measurement, clamping test of lead-in device, maximum positive pressure test, leak test, ventilation test, dilution test, minimum positive pressure check, protection Device operation reliability test and determination of efficiency.

5. The inspection items of dust-proof protective explosion-proof motors include: structural inspection, impact resistance test, enclosure protection level test, temperature measurement, clamping test of lead-in device, and determination of efficiency.
