Fan debugging

1 fans allow full voltage start or start, but should pay attention to the full voltage starting current is about 5~7 times the rated current, the buck start to turn away from the square of the current, when the power grid capacity is insufficient, should be used to start the buck. (when the power is greater than 11KW, it is advisable to use the buck start.) 2 fans in the test, should be carefully read the product manual, check the wiring method is consistent with the wiring diagram, should be carefully check the supply fan power supply voltage is in line with the requirements of the power supply is lack of phase or the same phase, the capacity of the electric components. 3 the number of test runs is not less than two people, one control power supply, a person to observe the operation of the wind turbine, found abnormal phenomenon immediately stop check; first check the rotation direction is correct; the wind machine starts running, should check the running current is balanced, the current is over rated current; if not normal phenomenon, should stop check. After five minutes of operation, the machine can check the abnormal phenomenon of the fan, and no abnormal phenomenon can be confirmed. 4 double speed fan test, should start at low speed, and check whether the rotation direction is correct; starting at high speed when the wind turbine must be at rest before starting, in order to prevent the high speed reverse rotation, the switch trip and motor damage. 5 when the fan reaches the normal speed, the input current of the wind turbine should be checked, and the operating current of the fan can not exceed the rated current. If the current exceeds the rated current, the voltage of the supply fan should be checked. 6 the motor power required by the wind turbine is the power of the centrifugal blower and the wind turbine under a certain working condition. If the inlet outlet is fully open, the motor may be damaged. When the wind turbine test is best to fan inlet or outlet pipe on the valve closed, the valve will gradually open up, to reach the required conditions, and pay attention to the operation of the wind turbine is more than the rated current.
