Explosion proof wall type square BWEXD-550 side wall ventilation exhaust

Explosion proof wall type square BWEXD-550 side wall ventilation exhaustAdopting wing shaped axial flow impeller and low-noise external rotor motor direct transmission or aluminum alloy impeller+motor direct connection, the square shell design can be easily installed on concrete walls, brick walls or light steel profiled wall panels, and the square rain cover structure is firm and aesthetically pleasing. It has the characteristics of low noise, large air volume, reliable operation, wide range of performance parameters, and easy installation, and is widely used for side wall ventilation and air exchange in factories, mines, workshops, and civil and commercial construction projects.

Explosion proof wall type square BWEXD-550 side wall ventilation exhaustGenerally used for side wall exhaust, equipped with a 45 ° rain cover (or specially manufactured to 60 °) and insect proof net (can prevent insects from flying into the workshop through lights at night). The side wall air supply fan model can be made into DWSP (WSP) according to the needs, equipped with a 90 ° rain cover (windproof, rain proof, dust proof) and insect proof net (can prevent insects from flying into the workshop through lights at night).

Explosion proof wall type square BWEXD-550 side wall ventilation exhaustThe installation and maintenance instructions for maintenance are as follows:
1. The foundation for the maintenance and installation of WEX side wall fans must be higher than the roof, with a flat surface to prevent water leakage, and foundation bolts must be pre embedded.
2. Add a layer of 5mm rubber plate between the maintenance base and foundation of the WEX side wall fan to reduce vibration. The anchor bolts should be equipped with spring washers to prevent loosening during use.
3. Before debugging and operating, a detailed inspection of all components of the fan should be carried out, and the rotating impeller should be free from any stagnation, jamming, or rubbing.
4. At the beginning of the trial operation, first jog the motor to check if the impeller rotation direction is correct (when looking down, the impeller should rotate counterclockwise).
5. There should be no abnormalities during trial operation or normal use, and the voltage, current, vibration, and noise should be within the normal range.
6. During operation, if any of the following situations occur, the machine should be stopped immediately, the cause should be identified, and the machine can only be started after waiting in line for the fault.
