Issues with the connection of the circulation fan in the coal powder preparation process!
Thread Content
Taking into account the whole coal powder preparation process, is it more appropriate to use couplings for connecting the circulation fans?

There’s a big difference: one uses a coupling for a rigid connection, while the other uses a variable-speed connection.
Some are connected using couplings, while others employ hydraulic couplings. If funding is not a concern, it is recommended to use hydraulic couplings, as they offer higher levels of safety and stability
For the centrifugal fans we used in the past, hydraulic couplings were also employed. With such large-scale fans, using couplings for connection can lead to elastic deformation, which causes significant damage to the bearings. The difference between the two is that one is a hard link and the other is a soft link.
This type of fan has high starting torque, so a fluid coupling is necessary.
