The centrifugal curtain machine is a complicated structure, which is mainly composed of air intakes, air valves, impeller, motor and air outlet.The effect of centrifugation varies from status, so it will affect the effect of centrifugation.To adjust the centrifugal air screen machine to a better state, you can start in many ways.Lets learn the debugging method of centrifugal air screen.
1. The centrifugal air curtain allows full voltage start or lower voltage band power, but please note that the current at full voltage start is about 5-7 times the rated current.The decompression starting torque is proportional to the square of the voltage.When the power grid capacity is insufficient, the starting start is used.
2. When trying to run the centrifugal screen, carefully read the product manual to check whether the wiring method is consistent with the wiring diagram; you need to carefully check whether the working voltage of the fan power supply meets the requirements, whether the power supply is different or the same phase, and whether the capacity of the power disk component meets the requirementsEssence
3. If there are more than two people in the trial operation, one person controls the power supply, and the other observes the operation of the fan.If the abnormal phenomenon is found, the inspection is stopped immediately; first check whether the rotation direction is correct; after the start and operation of the centrifugal fan, immediately check whether the running current of each phase is balanced and the current exceeds the rated current; if there is an exception, please stop the inspection.After 5 minutes of running, the stop checks whether the fan is abnormal, and confirm that there is no abnormality before turning on.
4. When trying to use a centrifugal air -to -air screen machine, start at a low speed to check whether the rotation direction is correct; when starting at a high speed, the fan must be stopped before starting, so as to avoid high -speed reversal, resulting in disconnection or motor damage.
5. When the centrifugal air curtain reaches the normal speed, the measuring fan input current is normal, so that the operating current of the centrifugal air curtain does not exceed its rated current.When the running current exceeds the rated current, check whether the power supply voltage is normal.
6. The power required for the motor of the centrifugal air curtain means that in some cases, compared with the case and fan of the centrifugal air curtain machine, the power required when the air inlet is fully opened.If the motor runs completely when the inlet is fully opened, the motor may be damaged.During debugging, turn off the valve of the fan inlet and exported pipelines, and slowly open the valve after running.Before meeting the necessary conditions, pay attention to whether the working current of the fan exceeds the rated current.
The above is the debugging method of a centrifugal curtain machine
