Debugging a smelter dust blower fan to allow full voltage start or step-down start, but it should be noted that the starting time of the current total pressure of about 5 to 7 times the rated current, voltage starting torque is proportional to the square of the current, when insufficient grid capacity, should be used to step-down start. (When the power is greater than 11KW, should adopt the buck starts.) When the fan test, you should carefully read the product manual, check the wiring method is consistent with the wiring diagram; should carefully check the operating voltage of the power supply fan meets the requirements, the power supply is missing phase or in phase with the capacity of the electrical components to meet the requirements. 2 test no less than two people, one person to control the power of a person to observe the functioning of the fan, found anomalies immediately stop inspection; First check the direction of rotation is correct; after fan start running, you should immediately check whether the current balance of the operation, the current does not exceed rated current; if there is a normal phenomenon, should stop to check. Five minutes after the operation, the fan down to check whether there are anomalies, confirmed that no anomalies start running again. 3 two-speed fan test, you should start at low speed, and check the direction of rotation is correct; it must be the fan speed to a standstill after the start when starting to prevent reverse rotation speed, causing the switch to trip and electrical damage. When the fan up to speed, the fan should detect the input current is normal, the fan operating current can not exceed the rated current. If the current exceeds the rated current is running, you should check the supply voltage is normal fan. 4 fan motor power is required to refer certain conditions, for centrifugal fan and wind chassis, the power required for the larger air intake fully open. If the inlet operated fully open, the motor may be damaged. When the fan blower test the best import or export pipeline valve is closed, will gradually open the valve operation, until the desired conditions, and pay attention to the fan operating current exceeds the rated current.
