Reason of adding soft connection to Axial flow Fan and Speed Regulation of single Phase Capacitance

Wuxi JN Fan Co.,Ltd | Updated: Mar 08, 2018

1. May I use an axial fan in the workshop?

Although the axial flow fan can be used in the workshop, it is better to use the negative pressure fan because it is better than the axial fan. As for the number of fans in use, it is necessary to do some calculation work. First calculate the volume of the factory, and then according to the flow of the negative pressure fan, to determine the fan per minute ventilation number, and then, the number of fans can be determined.

2. Single-phase capacitive axial fan, how to adjust speed?

Mode 1: use capacitors with the same capacity as existing capacitors, both of which are in series.

Mode 2: use an electronic stepless governor with the appropriate power. In connection, one end of the motor.

3. Should soft connections be added at both ends of the axial fan?

Both ends of an axial fan need to be connected with a soft connection. Because if there is no soft connection, the fan will produce vibration during the operation. Especially in startup and shutdown, there will be a large amplitude of vibration. Furthermore, if directly connected with metal ducts, after the axial flow fan is used for a period of time, the air duct will be damaged or even damaged, so it is necessary to add soft connection to avoid this problem.http://www.jnblower.com/
