When testing, you should carefully read the product manual to check whether the wiring method is consistent with the wiring diagram; you should carefully check whether the working voltage of the supply power supply meets the requirements, whether the power supply is missing or the same as the phase, and whether the capacity of the distribution component meets the requirements.When testing, start at a low speed to check whether the rotation direction is correct. When starting at a high speed, it must be started after static stop to prevent high -speed reverse rotation, causing switching to switch and damage to the motor.
The axis flow fan allows full -voltage starting or antihypertensive electric.However, it should be noted that the current at the time of full pressure start is about 5-7 times the rated current. The decompressor starting torque is proportional to the square of the voltage. When the power grid capacity is insufficient, the lower voltage start should be used.The number of people was not less than two during the trial. One person controlled the power supply.
1. First check whether the rotation direction is correct;
2. After the axis fans start to run, check whether the running current of each phase is balanced and the current exceeds the rated current;
3. If there is an abnormal phenomenon, it should be stopped for inspection.
4. After five minutes of running, the downturn to check whether the fan is abnormal, and confirm that there is no abnormal phenomenon before turning on.
The motor power required by the axis flow refers to the greater power required for the firbox and the air inlet when the air inlet is opened under certain operating conditions.If the air inlet runs fully, the motor is in danger of damage.When the fan test drives, the valve imports or the valve on the export pipeline is turned off. After running, the valve is gradually turned on to reach the required condition, and the current of the fan is more than the rated current.When the axis flower reaches normal speed, it should measure whether the input current of the fan should be normal, and the operating current cannot exceed its rated current.If the operating current exceeds its rated current, check the voltage of the supply is normal.If each component of the axis flowers is not running, it can be detected during the trial -trial period, thereby improving the overall efficiency.
The above is the trial matters about the axis flow fan. I hope that the above content can be helpful to everyone. Thank you for your viewing and support. In the later period, more information will be sorted out. Please pay more attention to us ——
