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.

High voltage explosion-proof fanExplosion-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.

High voltage explosion-proof fanExplosion proof refers to a motor whose casing is designed and manufactured according to specified conditions, which can prevent dust from entering the motor casing, or although it cannot prevent dust from entering, its entry amount does not hinder the safe operation of the motor, and the accumulation of internal dust is not easy to cause ignition hazards. When used, it will not cause explosive dust mixture explosions in the surrounding area. Mainly used in coal mines, oil and gas, petrochemicals, and chemical industries, it is also widely used in sectors such as textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, and pharmaceuticals.

The explosion-proof performance of the explosion-proof vortex fan meets the relevant standards newly issued by the country, followed by high explosion-proof performance and very reliable operation. The protection level of the motor is IP55, and the shaft through position adopts a V-shaped shaft seal ring. The junction box adopts a circular sealing ring with a dense sealing ring, which improves the processing accuracy of the main components. The machine base also adopts a parallel and vertical heat sink structure, increasing the heat dissipation area and other electrical and mechanical design measures. In terms of dust and water resistance, it is one level higher than the IP54 of the YB series, making the operation of the motor more reliable.

Explosion-proof fanInstructions for Use
1. Before installation, the fan should be carefully inspected for any damage or deformation. If there is any damage or deformation, it should be repaired properly before installation can proceed. 2. During installation, pay attention to checking whether the connecting parts are loose, and the gap between the blades and the air duct should be even and not collide. 3. The weight of the connecting air duct should not be borne by the air duct of the fan, and additional support brackets should be added during installation. 4. A collector must be installed at the air outlet of the fan, and it is recommended to install a protective net. 5. The fan base must be naturally connected to the foundation plane, and it is not allowed to forcefully connect the base by knocking it to prevent deformation. During installation, the base should be calibrated, iron pads should be added, and the basic horizontal position should be maintained. Then, the anchor bolts should be tightened. 6. After installation, experiments must be conducted first, and formal use can only be allowed after normal operation.

Explosion proof high-pressure fanCircular explosion-proof fanMaintenance and storage
1. The usage environment should be kept clean regularly, the surface of the fan should be kept clean, and there should be no debris at the inlet and outlet. Regularly remove dust and other debris from the fan and pipes.
2. It can only be operated when the fan is in positive gear, and at the same time, the power supply facilities must have sufficient capacity and stable voltage. It is strictly prohibited to operate without phase. The power supply line must be a line and temporary lines should not be used for long-term power supply.
During the operation of the fan, if abnormal noise is detected, the motor is severely overheating, the casing is electrified, the switch trips, and the fan cannot be started, it should be stopped immediately for inspection. For safety reasons, maintenance is not allowed during the operation of the fan. After maintenance, a trial run should be conducted for about five minutes to confirm that there are no abnormal phenomena before starting the machine.
4. According to the environmental conditions of use, lubricating grease should be supplemented or replaced irregularly for the bearings (motor enclosed bearings do not need to replace lubricating grease during their service life). To ensure good lubrication of the fan during operation, the oiling frequency should not be less than 1000 hours per time. For enclosed bearings and motor bearings, ZL-3 lithium based lubricating grease should be used to fill 2/3 of the inner and outer rings of the bearings. It is strictly prohibited to operate without oil.
5. The fan should be stored in a dry environment to prevent the motor from getting damp. When storing fans outdoors, rain protection measures should be taken. During storage and handling, the fan should be protected from collision to prevent damage.
