Centrifugal fan, which is one of the fans, and is widely used, from the present point of view. In addition, it is also a common type of wind turbine, as well as important products and keywords on the website. Then, based on these factors, the following will continue to introduce this type of fan, so that everyone can have learning content, and then to achieve the correct use and rational use of the fan.
1. Does the centrifugal fan allow full pressure or reduced pressure to start?
Centrifugal fans can be started at full pressure or reduced pressure. However, there are some precautions, specifically: when the centrifugal fan is started at full pressure, the starting current should be 5 to 7 times the rated current; when it is started at reduced voltage, the reduced voltage starting torque is between the square of the voltage , Should be a proportional relationship.
2. Is there a requirement for the number of people in the trial run of the centrifugal fan?
The test run of a centrifugal fan is required in terms of the number of people. Generally speaking, no less than two persons are required. One person controls the power supply and the other person observes whether the fan is operating normally. If an abnormality or problem occurs, it should be shut down immediately for inspection. Delay, so as not to damage the fan or even cause serious consequences.
3. Are there any precautions for the trial run of the two-speed centrifugal fan?
The two-speed centrifugal fan is one of the centrifugal fans. Therefore, there are precautions during the test run. The specifics are: the fan should be started at a low speed first, and then check whether its rotation direction is correct. If you want to start at a high speed, you have to wait until the fan is stationary.
4. How to correctly understand the motor power in a centrifugal fan?
In a centrifugal fan, the correct understanding of its motor power is: under certain working conditions, on the centrifugal fan and the air box, the power required when the air inlet is fully opened. However, if the fan is operated when the air inlet is fully opened, the motor may be damaged. Therefore, the valve on the pipeline should be closed first, and then gradually opened until it reaches the required working condition position, rather than all at once. turn on.
