FB-3/2.2kw high-voltage explosion-proof fan

Explosion proof high-pressure blowerThe explosion-proof performance complies with the provisions of GB3836.1-2000 "Electrical Equipment for Explosive Gas Atmosphere Part 1: General Requirements" and GB3836.2-2000 "Electrical Equipment for Explosive Gas Atmosphere Part 2: Explosion proof Type'd '", as well as the provisions of IEC79-7, BS4683 and EN50018, and is made into an explosion-proof type. The explosion-proof signs are Ex dI, Ex dIIAT4, and Ex dIIBT4, suitable for places where explosive gas mixtures are present.

FB-3/2.2kw high-voltage explosion-proof fanCharacteristic introduction:

1. Aluminum die-casting impeller: generates stable airflow and efficient flow rate

2. Dynamic balancing impeller: smoother operation, no vibration during operation

3. Double covered bearings: prevent grease leakage and increase the reliability of operation

4. Dustproof shaft seal: prevents dust intrusion and extends bearing life

5. Combination of motor spindle and impeller inlay: There is no need for connectors, belts, or gears, and there is no concern of breakage or wear

6.50/60HZ and wide voltage design: reduces manufacturer's inventory demand for 220V to 660V voltage

7. High efficiency cooling fan: effectively cools the motor and air pump, enabling them to operate efficiently and with low noise

8. Embedded thermal protector (optional): More effective in preventing motor overheating and enhancing product reliability

9. Miniaturization design: allowing users to use and install space more effectively

10. Detachable fittings (optional): easier to install.

FB-3/2.2kw high-voltage explosion-proof fanAdvantages:

1. Compact structure: Beautiful appearance, good stability, easy installation and maintenance.

2. Smooth operation: The optimized design of the impeller reduces axial force to a low level and has an efficient impeller. After static and dynamic balance correction, the whole machine runs smoothly. Without any vibration reduction device, the bearing amplitude is ≤ 0.04mm.

3. Low noise: When the fan is running, there is no mechanical friction, and a reasonable blade shape is used to reduce the sound. The noise generated by the fan is high-frequency noise, and as long as there are obstacles, it can be soundproof, so there is almost no noise outside the fan room.

4. Oil free machinery: The fan bearings are lubricated with grease, and the bearing life is over three years. The fan does not produce oil or gas during operation. Special requirements for fans, using molybdenum disulfide lithium grease to lubricate bearings.

5. Impeller: The impeller adopts a special composite linear design, which reduces internal leakage and improves volumetric efficiency.

6. Easy to adjust: The inlet butterfly valve adjusts the flow rate, and the outlet butterfly valve adjusts the pressure.

7. Driving method: Typically, a two pole asynchronous motor is used, but a four pole motor can also be used for driving. Depending on the user's power grid, motors with different voltages can be used.

8. Sealing: In addition to the inlet ring, each stage impeller is equipped with labyrinth seals between stages and at both ends of the casing to prevent gas leakage.
