1. Carefully read the use of explosion -proof use clarification to understand the standards, methods, leaf rotation directions, and air flow in and out direction of explosion -proof. Check again if there is no lack of explosion -proof parts, otherwise the device should be used after correction.
2. During the work process, explosion -proof fans found that the fan has abnormal sounds, severe fever of the motor, charged shell, switching, and unable to start. It should be immediately stopped to check.To ensure safety, repair is not allowed to be repaired in the work of the fan.After the maintenance, the trial work should be carried out for about five minutes to admit that there is no abnormal phenomenon and then start the work.
3. The power control box for explosion -proof fans is necessary to match the corresponding fan (referring to power, voltage, control method, etc.).
4. It can work under the normal normal situation of explosion -proof fans. At the same time, it is necessary to maintain sufficient power supply equipment. The grounding of the fan shell or motor shell is necessary to be reliable, the voltage is stable, and the lack of phase work is prohibited.
5. Should always keep the explosion -proof fan cleaning, and there should be no debris in the entrance or air outlet.Regularly eliminate miscellaneous objects such as dust in the fan.
6. After the explosion -proof fan device, use your hands or leverage to mobilize the impeller to see if there is too tight or rubbing. There is no item that hinders rotation. There is no abnormal phenomenon before trying.
The above is the precautions for using explosion -proof shaft flowers
