Working principle of explosion-proof fanDue to the centrifugal force acting on the air in the middle of the impeller blades, it moves towards the edge of the impeller. The circulating airflow generated by the rotation of the impeller enters the annular cavity of the pump body where the air circulates again in the same way from the starting point of the blades.
It uses an explosion-proof shell to separate electrical components that may generate sparks, arcs, and hazardous temperatures from the surrounding explosive gas mixture. However, this type of casing is not sealed, and explosive gas mixtures around it can enter the interior of the motor through the gaps between the joint surfaces of various parts of the casing. When in contact with ignition sources such as sparks, arcs, and dangerous high temperatures inside the casing, an explosion may occur. At this time, the explosion-proof casing of the fan will not be damaged or deformed, and the explosive flame or hot gas cannot ignite the surrounding explosive gas mixture when it is transmitted through the gap between the joint surfaces.

Explosion proof fans mainly have the following advantages
1. Energy saving and consumption reduction: Depending on different working conditions, the energy-saving effect can reach 10% and 50%;
2. Equipped with soft start function, the starting current is small, the starting torque is large, up to twice the rated value, the torque ripple of the motor is small, and the operating torque of the motor is high;
3. Adjustable speed with high efficiency, reaching over 95%; Realize smooth stepless speed regulation, convenient speed regulation;
4. There are multiple protection functions such as overvoltage, undervoltage, overcurrent, overload, and phase loss, which ensure accurate and reliable protection, thereby reducing the incidence of accidents and providing timely fault information;
5. Frequency: 10Hz/70HZ Voltage: 110V-615V (applicable in all countries). If special voltage is required, it can be customized according to requirements;
6. Improve the power factor of motor operation and extend the service life of motors and other equipment. After adopting variable frequency speed regulation, soft starting and soft braking can be achieved with almost no impact, avoiding 34 times the impact current of water resistance soft starting, and greatly extending the electrical and mechanical life of the motor stator, rotor shaft, and bearings;
7. It can improve the automation and process level of the entire system, with simple on-site operation, less maintenance workload, and cost savings.
