Explosion proof motors belong to a branch of motors and belong to special motors. They are mostly used in environmentally hazardous, flammable and explosive places, and have the function of preventing the spread of explosion sources, so they are called "explosion proof motors". Motors with explosion proof enclosures are called "explosion proof motors". The mark of the explosion proof motor is "d". In order to complete the explosion proof and explosion proof functions of the explosion proof enclosure, there are special requirements for the shape, material, volume, structure, etc. of the explosion proof enclosure.
In some occasions with explosion risk, when gas or dust encounters ignition source or low temperature, it will extinguish or explode. While the electrical control devices are running, they will produce an electric arc or electric spark. These are strong ignition sources, they can explode when they encounter explosive dust or gas.
The explosion proof VFD is mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.
Application of explosion proof motors: 1. Workshops prone to produce dangerous gases; 2. Workshops with more dust; 3. Workshops with dangerous liquids; 4. Industrial workshops like workshops in other flammable and explosive industries such as paper making and textiles. As the main electric frequency converter, explosion-proof motors are usually used to drive pumps, fans, compressors and other transmission machinery.
There are many types of explosion proof motors. To ensure safe production in the environment of explosion hazard areas, the selection of explosion proof motors is very important. When selecting an explosion proof motor, you must understand its explosion proof performance. Only by choosing a suitable explosion proof motor can you ensure the safety of use and not waste resources.
