During the operation of the double inlet radial centrifugal fan, when it reaches its normal speed, it is necessary to effectively measure whether the input current of the fan is normal, and the operating current of the double inlet radial centrifugal fan cannot exceed its rated current, if When the current flowing exceeds its rated current, it is necessary to effectively check whether the supplied voltage is normal.
The motor power required for the dual-inlet radial centrifugal fan is mainly under certain working conditions, so that the centrifugal fan and the wind chassis can be effectively used. When the air inlet is fully opened during operation, the required power is higher. Big. If the air inlet is fully open for operation, there is a risk of damage to the motor. When testing the fan, it is best to close the valve on the inlet or outlet of the fan. After the operation, the valve is gradually opened to reach the required working condition, and the operating current of the fan exceeds the rated current.
During the assembly process of the double-inlet radial centrifugal fan, the position of the casing is mainly determined by the rotor shaft center line during the operation, and the air intake of the impeller inlet and the casing are taken. The axial and radial clearance between the ports is high enough to the extent specified in the equipment technical documentation, and the anchor bolts are checked for tightness.
