Centrifugal fan [1] is based on the principle of potential energy is converted to kinetic energy, the use of high-speed rotation of the impeller the gas to accelerate, then slow down, change the flow of the kinetic energy into potential energy (pressure). In the single-stage centrifugal fan, the gas enters the impeller in the axial direction, changing the gas flow through a radial impeller, and then into the diffuser. In the diffuser, the gas flow direction changes cause deceleration that the deceleration effect the kinetic energy is converted into pressure energy. Debugging method centrifugal fan is a centrifugal fan device structure complex parameters, there are air inlet valve, impeller, motor, the outlet composition. In different states, the effect is not the same centrifugal fan. Therefore, the role of the centrifugal fan, the different operating conditions section is not uniform, the effect of centrifugal fans will be affected. The centrifugal fan debugging to the best condition, it can start from several aspects. 1, centrifugal fans allow full pressure start or step-down power, it should be noted that current at full voltage starting time is about 5-7 times the rated current, voltage starting torque is proportional to the square of the voltage centrifugal fan manufacturers, when grid capacity insufficient, should step-down start. 2, when the centrifugal fan test, 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 is not met, the power is the same phase or phase, the distribution of the electrical components capacity to meet the requirements. 3, the test is not less than the number two, a controlled power supply, one fan running observe, abnormal phenomenon immediately stop inspection; First check the direction of rotation is correct; after centrifugal fan starts running, you should immediately check the operating current of each phase is balanced the current exceeds the rated current; if not normal, should be down to check. Run five minutes after centrifugal fan, the fan down to check whether there are anomalies, confirmed that no anomalies start running again. 4, two-speed centrifugal fan test, you should start low, check the rotation direction is correct; it must be at the start and then start high-speed fan still prevent reverse rotation speed, causing the switch trips and motor damage. 5, when the centrifugal fan up to speed, the fan should be measured input current is normal, centrifugal fan operating current can not exceed the rated current. If the operating current exceeds the rated current, should check the supply voltage is normal.
