Fluid coupling question

Fluid coupling question

Fluid coupling question

(OP)
I have a fixed speed motor with a fluid coupling connection to compressor shaft. Variable speed is achieved by scoop tube fluid level control.

Can the motor can trip on high power due upsets on process side given that the torque transmission is through a fluid coupling ?

RE: Fluid coupling question

I would say YES...
 
      Hope this helps

RE: Fluid coupling question

It absolutely can.  Whatever load the process puts on the motor via the drive, hydraulic or not, the motor is going to try to pull.

I've seen it on fans that were overloaded under start up conditions.  It was a question of which would go first, the motor on high amps or the drive on high oil temperature.

Once the process was fixed, the motor/coupling system settled down.
