When introducing the wiring of explosion-proof motor? Sima motor manufacturers first put forward a simple question for you? Do you know what explosion-proof motor is? What is the explosion-proof motor used for and what range is the motor mainly used in.

Next, Sima motor manufacturers will give you a brief introduction.

Explosion proof motor is a kind of motor that can be used in inflammable and explosive places, and it will not produce electric spark in the process of motor operation.

So, what is the application scope of electric explosion-proof machine? Application scope: coal mine, oil and gas, petrochemical and chemical industry, as well as in textile, metallurgy, urban gas, transportation, grain and oil processing, paper making, medicine and other departments are also widely used. As the main power equipment, explosion-proof motor is usually used to drive pumps, fans, compressors and other transmission machinery.

After understanding the introduction of explosion-proof motor, you must have a certain understanding of it. Then, what should you pay attention to when wiring explosion-proof motor? Here are some answers for you.

1. After the junction box is installed, check the electrical clearance and creepage distance: the minimum electrical clearance of 380 / 660V is 10mm, and the minimum creepage distance is 18mm. The minimum clearance of 1140V is 18mm and the minimum creepage distance is 30mm.

2. The inlet of the junction box is sealed by pressing the rubber ring. The weakness of this structure is the aging and elastic failure of the rubber ring, which makes the cable and rubber ring inconsistent.

3. For the junction box with double outlet, the unused outlet shall be blocked with metal seal with thickness not less than 2mm. The outer diameter of the metal seal shall be close to the inner diameter of the outlet hole of the inlet and outlet device, so as to ensure that the pressure plate or compression nut uniformly presses the tight seal ring to achieve reliable sealing.

Why do explosion-proof motors have all kinds of faults? Xima motor manufacturer tells you that the main reason is that the insulation is affected by moisture. As the explosion-proof motor is affected by moisture, water droplets will appear in its inner cavity, thus increasing the frequency of failure

The above is the introduction of Sima motor manufacturers, I hope our simple introduction can help you! If you want to know something about other motors, pay attention to Sima motors, or call us to learn more!
