The debugging methods centrifugal fan is a complicated device structure, the main air inlet damper, impeller, motor, outlet composition. In a different state, the effect of the centrifugal fan is not the same. Therefore, a different part of the operating conditions do not agree, the effect of the centrifugal fan will be affected. The the centrifugal fan debugging to the best condition, you can start from a number of aspects. Centrifugal fan allows full pressure start-up or step-down electric, but it should be noted that the full voltage starting current is approximately 5-7 times the rated current, voltage starting torque is proportional to the square of the voltage, when the lack of grid capacity should be used voltage starting. Centrifugal fan in the trial run, should carefully read the product manual, check the wiring method is consistent with the wiring diagram; should carefully check the operating voltage of the supply fan power is not required, the power is missing phase or in phase, with the electrical components whether the capacity to meet the requirements. , Commissioning no fewer than two people, one person to control power, one to observe the fan running, immediately stop inspection found anomalies; First check the correct direction of rotation; centrifugal fan starts running, you should immediately check the current balance of each phase operation , if it is not a normal phenomenon, whether the current exceeds the rated current; should stop check. Five minutes after the operation, down to check fan anomalies, confirm no abnormality and then start running. The test of the two-speed centrifugal fan, you should start low speed, check the direction of rotation is correct; must be the starting high-speed fan still and then start to prevent high-speed reverse rotation, causing damage to the switch tripped and motor.
