Explosion proof electric drum is a new type of driving device for belt conveyors, which has gradually replaced the external driving device composed of a reducer and an electric motor. It is mainly used in fixed and mobiles belt conveyors, replacing traditional electric motors. The reducer is a separate driving device outside the driving drum. The advantages of explosion-proof electric drum are as follows:
1. Compact structure, small volume, and light weight;
2. Large transmission ratio range;
3. Electric drum drive has high efficiency;
4. Characterized by overload and impact resistance;
5. Smooth transmission and long service life;
6. Overbudget, good performance, strong overload capacity;
7. The electric drum has a one-way rotation function to prevent reverse rotation. There is a certain amount of cooling oil inside the drum. Due to the continuous rotation of the drum body, the oil scraper on the drum body continuously pours the oil onto the motor and gears, taking away the heat generated by the motor and gears during operation, transferring the heat to the drum body wall, accelerating the motor's heat dissipation, and lubricating the gears.
For explosion-proof electric drums, their working conditions generally need to meet:
1. The higher temperature of the conveyed material cannot exceed 60 degrees Celsius;
2. Use frequency 50Hz and voltage 380V;
3. The altitude should be 1000 meters lower than the horizontal plane;
4. The working environment temperature is above minus 15 degrees Celsius and below 40 degrees Celsius;
The characteristics of explosion-proof electric drum are:
1. In terms of maintenance, it is safe to use and has a long service life;
2. Due to its simple structure, it occupies less space on the site;
3. Meet the working requirements of braking, rubber coating, reverse check, etc;
5. Its sealing performance is good, so the working environment does not need to ensure dryness and less dust like other rollers.
With the development of the economy and the advancement of technology, explosion-proof electric drums are used as the power source for belt conveyors and lifting equipment. Explosion proof electric drum is widely used in mining, metallurgy, chemical industry, coal, building materials, power, grain and transportation sectors.
