1. Is the horizontal and vertical installation of the axial fan having an effect on the use of the fan?

There are two installation modes of axial fan, horizontal installation and vertical installation, and the choice of which one is based on the use environment and requirements of the fan, and they have no effect on the use of the fan. Because either way, is to achieve this purpose.

2. How can the 220 connection and 380 connection in the axial flow fan be distinguished?

The 220 connection and 380 connection in the axial fan, which is to be distinguished, is very simple. As long as it is measured with a multimeter or a wiring board, it can be achieved. If there is a wire connection or a capacitor in the outer line, it is 220V connection; if the three lines are not connected to the shell, and the resistance phase between the two lines The same or similar, it is the 380V connection.

3. Must a shield be installed during the use of the axial fan? How to distinguish between an axial fan and a centrifugal fan on the drawing?

Axial-flow fan in use, the shield is not necessary, according to the product requirements to determine whether to use.

On the drawing, the axial fan and centrifugal fan are distinguished by the shape of the fan shell, the gradually open type is the centrifugal fan, and the circular shell is the axial flow fan.

4. What is the purpose of using axial flow fans in transformers?

Axial flow fans are used on transformers , and only one purpose is to reduce the temperature of the transformer coil and the iron core so as to ensure the normal operation and use of the transformer . Therefore , it is necessary to use the axial flow fan on the transformer because it has an irreplaceable role.
