I wonder how much you know.Fire hood is a complicated equipment, mainly including air inlets, air valves, impeller, motor and air outlet.Fire ventilation equipment has different effects under different conditions.Therefore, the operating conditions of different parts are inconsistent, which will affect the effect of fire and ventilation equipment.In order to make 3C in a good state, we can start from multiple aspects.
The 3C fan allows full-voltage startup or antihypertensive electric, but the current should be noted that the current at the time of full voltage is about 5-7 times the rated current.When the power grid has insufficient capacity, the pressure reduction should be used.
When debugging the dual -speed 3C fire exhaust fan, start at a low speed to check whether the rotation direction is correct.When starting at a high speed, wait for the fire ventilation equipment to stop before starting to prevent high -speed reversal, switch the card, and the motor is damaged.
During the trial operation of the 3C fan, there must be no less than two people.One control power supply, and the other observes the operation of fire ventilation equipment.If there are abnormalities, stop the inspection immediately.First check whether the rotation direction is correct; after the launch of the ventilation equipment of Henan, immediately check whether the running current of each phase is balanced and the current exceeds the rated current.If there are abnormalities, stop checking.After running for 5 minutes, stop checking whether the fire and ventilation equipment is abnormal. After confirming that there is no abnormal phenomenon, start the machine.
When the 3C fan reaches the normal speed, the input current of the fan should be measured normally, and the operating current of Henan ventilation equipment shall not exceed the rated current.If the working current exceeds the rated current, check whether the power supply voltage is normal.
Do the above that can basically guarantee that the 3C fan is in a good state
