FALK-REXNORD – TRUE TORQUE FLUID COUPLINGS
- Description
Description
Product detail:
Without the fluid coupling, the motor instantly transmits its locked rotor torque (starting
torque) to the driven machine (point A at right). Then, it quickly reaches and applies
the breakdown torque (point B). For common applications, locked rotor and breakdown
torque often approximates 200% or more of the motor nameplate rating.
Damage can result if the required break-away starting torque of the driven machine is
significantly less, because the machine will be abruptly accelerated to rated speed.
With a fluid coupling installed, however, the torque to the driven machine starts at zero
(Point C) and gradually increases as the coupling impeller accelerates to point D.
When the output torque of the fluid coupling exceeds the break-away starting torque of
the driven machine (point D), the driven machinery gradually accelerates (right half of
chart). As the machine comes up to rated speed, the slip of the fluid coupling decreases
to (point E) and uniform power is transmitted at maximum efficiency.
