I have a supplier trying to sell a tri-axial sensor to me, I have the following concerns.

1) How does using it save time really?

2) Considering the analyzer used on site is a single channel analyzer how would it work; does it need a special mount.

3) how would the spectrum display look like, would the resultant measurement be a single spectrum or 3 different spectrums?

I attached a picture of a mount i saw over the internet, if this mount is installed on one axis of an equipment, can i simply use this instead of a triaxial sensor

The time savings with a triax can only be realized with an analyzer that can process all three signals at the same time.  If your analyzer has just one channel, you could use a three position switch to take each axis at a time after mounting the triax and that would save the Time it takes to reposition a single axis accel to the next axis.

I built a data acquisition system for my service centers that takes all six axes on an electric motor simultaneously, and that is a major time saver.
Care must be taken when positioning the triax so the three reference positions are correct.  For example, the PCB/IMI 604B had a connector on the side of the accel body.  If the user placed it so the connector is in line with the motor shaft, then X,Y, and Z are all correct.

Placing the triax as close to the centerline of the shaft is also important.  It should never be mounted where one or more axes don't best represent the shaft centerline.

Hope this helps.
