Fire fire smoke is used to the fire system of various engineering buildings to discharge the strong fangs and steam body when the fire accident is generated, and increase the rescue and danger time.Work to reduce equipment failure.
1. After the installation is completed, check whether it rotates flexibly before starting the fan, and use the hand to mobilize the blade to check whether there is a jam or friction phenomenon, and whether there are remaining items or debris in all pipes.
2. When trying the dual -speed fan, start at a low speed and check the rotation direction.After the high -speed start, it is necessary to wait for the fire to smoke to start after the fire exhaust fan is restless, so as to avoid high -speed reversal, causing the switch to switch to the switch and the motor damage.
3. When the fan is tested, you should carefully read the product manual to check whether the wiring method is in line with the wiring diagram; you should carefully check whether the working voltage of the supply fan is met with the requirements, whether the power supply is missing or the same as the phase, and whether the capacity of the electrical component component isMeet the requirements.
4. After the fire exhaust fan reaches the normal speed, the input current is measured, and the overall operating current must not exceed the rated current.If the operating current exceeds the rated current, check the power supply voltage.
5. The number of people at no less than two people during the test ride. One person controls the power supply. One person observes the operation of the fan and found that the abnormal phenomenon is immediately shut down to check.First check whether the rotation direction is normal; after the fan starts, it should be immediately check whether the running current is balanced and the current exceeds the rated current; if there is an abnormal phenomenon, it should be stopped to check.After 5 minutes of transportation, the shutdown checks whether the fan is abnormal, and confirm that there is no abnormal phenomenon before turning on.
6. After the fan test stops, inspect the leaves and connecting bolts (composition: head: head and screw composition). There is no looseness. Only when everything is normal can they be put into operation. If there is a problem, it should be repaired in time.
The above is the debugging after the installation of the fire exhaust fan
