Variable frequency explosion-proof blower vortex fan

Variable frequency explosion-proof blower vortex fanStructural features: The fan is mainly composed of impeller, casing, air inlet, motor, connector, heat dissipation fan blades and other components. The impeller adopts a multi blade single inlet centrifugal impeller, made of high-quality galvanized or cold-rolled steel plates, and the blades are designed based on aerodynamic principles. The WQE type impeller consists of 10 aft tilting airfoil blades, a curved front plate, and a flat rear plate. The material is made of high-quality steel plates with high strength and durability, and has undergone strict dynamic and static balance correction. It has good air performance, high efficiency, and smooth operation. The air inlet adopts a convergent streamlined vortex reduction form, which reduces airflow loss and improves the efficiency of the fan. The fan casing is connected to the motor through a metal casting, and the motor shaft head is equipped with a cooling fan blade. The outer wall of the metal casting has high inlet and outlet pipe interfaces to cool the metal casting and shaft head, ensuring that the motor operates normally at high temperatures. The motor adopts a special high-temperature motor, and the fluid part of the fan is made of heat-resistant materials, with reliable cooling structure performance. Compared to boiler induced draft fans, it has the advantages of simple structure, easy maintenance, and high cost-effectiveness.

Advantages:

1. Energy conservation and consumption reduction. According to different working conditions, the energy-saving effect can reach 10% -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. 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 3-4 times the impact current caused by water resistance during soft starting. This can greatly extend the electrical and mechanical life of the motor stator, rotor shaft, and bearings

6. It can improve the automation and process level of the entire system, with simple on-site operation, less maintenance workload, and cost savings.
