The explosion-proof motor is actually a flameproof motor, which has a structure different from that of ordinary environmental use. The explosion proof dc motor can maximize the prevention of combustible gases and dust outside the motor from entering the inside of the motor, or if it does enter, it will not ignite the surrounding combustible gases and dust in the event of a short circuit fire inside, which does not cause the flame to ignite out of the casing.
To enclose electrical equipment in a casing that can withstand the explosive pressure of the internal explosive mixture and prevent the internal explosion from spreading to the surrounding explosive mixture of the casing structure (flameproof); to make the energized parts of the motor impossible to produce sparks, arcs, or dangerous temperatures that could cause an explosion, or to isolate the energized parts that may produce these phenomena from the explosive mixture so that they cannot come into contact with each other or reach a dangerous level of explosion (increased safety, ventilation, etc.).
There are many types of explosion-proof motors. In order to ensure safe production in explosive risk areas, the selection of explosion-proof motors is very important. When selecting explosion-proof motors, it is necessary to understand their explosion-proof performance. Only by selecting suitable explosion-proof motors can the use be guaranteed to be safe and not waste resources. Explosion-proof motors are mainly used in coal mines, petroleum and natural gas, petrochemicals, and chemical industries. In addition, they are widely used in textiles, metallurgy, urban gas, traffic, grain and oil processing, papermaking, medicine, and other sectors. As the main electrical transmission equipment, explosion-proof motors are usually used to drive pumps, fans, compressors, and other transmission machinery.
Explosion-proof motors have a motor structure different from that used in ordinary environments, which can prevent external gases and dust from entering the motor structure, or even if they do, they will not ignite the surrounding combustible gases and dust in the event of a short circuit fire inside.
Which locations require the power control equipment use of explosion-proof motors? Explosion-proof motors are widely used in environments with combustible gases, dust, and where there is a risk of ignition or even explosion due to overheating objects, such as coal mines, paint spray workshops, flour mills, machinery and warehouses for transporting and storing combustible gases and liquids (such as oil tankers, petroleum and natural gas transportation systems, gas stations and liquefied gas stations), and chemical workshops where combustible gases exist (such as ammonia production workshops).
