At present, by changing the speed ratio of the centrifugal fan, the change in the working pressure of the centrifugal fan becomes large, and the estimated purpose is achieved, and the exhaust amount and working pressure of the centrifugal fan are improved. On the contrary, the main advantage of this method is that there is no reduction in kinetic energy damage, and its economic development characteristics are better. In addition, the centrifugal fan can initiate a full operating voltage or reduce blood pressure, but pay attention to the start of the operating voltage, the current amount is about 5 to 7 times the rated voltage. How to more emphasize the output power of the outer rotor centrifugal fan?
How to adjust the output power and exhaust of the outer rotor centrifugal fan
At the first point, when the outer rotor centrifugal fan tests, please read the product model carefully. If the wiring method is not consistent Compact Fan Heater with the wiring method, carefully carefully carefully purchased the working standard voltage of the rotor centrifugal fan switching power supply, the switching power supply is Assessment is still in the same phase, whether the components of the regulator meet the regulations.
Second, ensure that the technical personnel investigates the operation of the outer rotor centrifuge fan, and immediately check the abnormal phenomenon. First, check if the rotation direction is appropriate, after the rotor centrifugal operation, check the current balance between the various working stages, the current does not exceed the rated voltage If there is an abnormality, please terminate the check, operate the outer rotor centrifuge fan for five minutes, check if there is an abnormality, determine if there is an abnormality, and then start.
Third, when the trial double-speed rotor centrifugal fan, start the low speed level, check whether the steering is appropriate. When high speed is started, the outer rotor centrifugal fan is static to prevent the switch trip or motor from being damaged by high speed. When the centrifugal fan reaches all normal speed, the type current of the centrifugal fan must be measured correctly. The current in the rotor centrifugal fan operation must not exceed its rated voltage. If the current exceeds the rated voltage, check if the power supply voltage is normal.
At present, in the outer rotor centrifugal fan regulation mode, by adjusting the opening degree of the safety valve or changing the gate valve, the characteristics of the pipe network system software can be changed, in which case the outer rotor centrifugal fan can be adjusted according to various methods, making it apply More powerful.
