Fellow Listmembers,
We need to control the speed (inclusive of a good acceleration
and deccelaration) of our hydraulic powered bottle filler and three (3)
proposals were being evaluated and are as follows:
A. Installation of a proportional flow valve and controller on
the existing and very reliable
hydraulic system.
B. Modification of entire drive system using a direct-drive
motor with a VFD;
C. Install a VFD for the existing 30 Hp drive motor for the
hydraulic pump to control the speed.
If you were in my position which one would you choose? Please
state pros and cons.
