Centrifugal fan is a disorderly equipment, mainly composed of air inlet, damper, impeller, electromechanical and air outlet. In the different state, the influence of the centrifugal fan is not the same. Therefore, some different operating conditions are not the same, and the influence of the centrifugal fan will be affected. Debugging the centrifugal fan to its optimum state can be used in many ways. Yuyao air cooler, Cixi air cooler

     1. The centrifugal fan allows full-voltage starting or step-down electric, but it should be stable. The current at the full-voltage starting is about 5-7 times the extra current. The step-down starting torque is proportional to the square of the voltage. When the grid capacity is lacking. , should use the buck start.

     2. When the centrifugal fan is in the test run, it should read the commodity imitation list and check whether the wiring method is consistent with the wiring diagram; it should be checked whether the power supply voltage supplied to the fan power supply is in compliance with the request, whether the power supply is phase loss or phase. Whether the capacity of the electrical components is in compliance with the request.

     3. The number of people in the test is not less than two. One person controls the power supply. One person inquires about the state of the wind turbine. The invention is very weather-stop and immediately shut down. Check whether the twisting bias is accurate. When the centrifugal fan starts to start, check the various things immediately. Whether the current is equalized, whether the current is beyond the extra current; if there is no abnormal weather, it should be stopped for inspection. After five minutes of things, stop the machine to check if the fan is very meteorologically.

     4. When testing the two-speed centrifugal fan, start the low speed first and check whether the torsional deflection is accurate. When starting the high speed, it is necessary to mobilize after the end of the fan to prevent the high speed reverse torsion, causing the switch to trip and the electromechanical damage.

     5. When the centrifugal fan reaches the abnormal speed, it should measure whether the output current of the fan is abnormal. The running current of the centrifugal fan can't exceed its extra current. If the operating current exceeds its extra current, check if the supplied voltage is abnormal.

     6. The electromechanical power required for the centrifugal fan means that under certain working conditions, the power required for the centrifugal fan breeze chassis and the air inlet is fully open. If the air inlet is fully open to stop things, there is a danger of damage to the electromechanical device. When the wind turbine is tested, it is best to close the valve at the inlet of the fan or the inlet pipe. After that, the valve will be drooped to open the hole to reach the end of the required working condition, and whether the current of the fan is exceeded.

     Strictly follow the above-mentioned debugging method to stop the commissioning of the centrifugal fan, which can make the power of the centrifugal fan reach 98% or more.
