Biogas booster explosion-proof fan

High voltage explosion-proof fan/explosion-proof blowerHow to choose?
The explosion-proof fan models for biogas transportation are complete, with detailed specifications for high, medium, and low pressure products. Therefore, for fan selection, customers only need to provide the technical parameters related to the fan to the equipment engineer, who has the technical ability to select the fan. As long as the technical indicators match, the fan selection can be completed.

Biogas booster explosion-proof fan

1: Oil seal: Use maintenance free shaft seals to separate the motor from the fan body.

2: It has dual functions of blowing and suction, and can be used for both suction and blowing.

3: Easy to install fan: The fan can be installed at any time in the place of use to supply compressed air or for vacuuming. And it can be installed in any horizontal or vertical direction.

4: Energy saving and environmental protection: Explosion proof high-pressure fans can work continuously, safely, reliably, and for a long time. All products are formed by heavy-duty casting and die-casting of alloy aluminum materials, possessing the advantages of traditional iron sheet or cast iron blowers such as "light weight and low energy consumption".

5: Low vibration: The mechanical precision is high, and the other components of the rotating part have undergone precise balance design, testing, and calibration, so the vibration rate is very low.

Biogas booster explosion-proof fanStructural description;
The explosion-proof structure of the electric fan has Ex dI, Ex dIIAT4, and Ex dIIBT4.
The protection level of the main casing of the electric fan is IP55.
The cooling method for the 3 electric fans is IC411.
The insulation level of the 4 electric fans is F level, and the stator winding has a large temperature rise margin and a long service life.
The 5 electric fans have a cylindrical shaft extension, which is driven by a coupling or gear.
The stator winding of the electric fan is made of high-strength enameled round copper wire, which is vacuum pressurized and immersed in paint to form a complete whole. The winding and insulation have good electrical, mechanical, moisture-proof performance and thermal stability.
The rotor of the 7 electric fan adopts a cast aluminum structure, and the rotor has undergone dynamic balance verification. The motor runs smoothly, with low vibration and noise.
The stator and rotor blades of the 8 electric fan are made of high-quality electrical silicon steel sheets with high magnetic conductivity and low loss, resulting in low motor loss and high efficiency.
9. The bearings for the electric fan are selected as low vibration and low-noise bearings for the motor. Double sided sealed bearings are used for machine seat sizes 160 and below, and waveform spring washers are installed at the shaft extension end to provide moderate pressure against the bearings and effectively suppress the vibration and noise generated during motor operation. For machine seat sizes 180 and above, inner and outer cover structures are used, and retaining rings are used for axial fixation at the bearing locations to effectively prevent axial movement of the motor rotor.
For the safe and reliable operation of electric motors, the bearing structure of motors with a base size of 180 and above is equipped with an oil injection device. For motors with a base size of 250 and above, a position for bearing temperature monitoring sensing elements is reserved.
10. Electric motor fan and fan cover: Electric motors with a base size of 280 and below use anti-static plastic fans, which have small rotational inertia and low loss. Motors with a base size of 315 and above use cast aluminum or steel plate welded fans, which are lightweight and strong. The entire series of fans are connected to the shaft with critical connections, ensuring reliable operation. The wind cover is made of steel plate structure, which provides a large ventilation area while preventing the intrusion of foreign objects of a certain size, ensuring smooth air flow.

Explosion-proof fanConsider installing it in a suitable environment during installation. For example, it can be installed in places where people do not frequently pass by, where it is non flammable, non explosive, prone to corrosion, and where the ground is flat. During installation, a certain amount of space should be left. In order to extend the service life of the fan, exhaust fans can be installed to cool down the surrounding environment. This approach protects personnel safety and provides convenience for daily work.
