TORQUE LIMITER AND TORQUE LIMITER OVERRIDE TEST

The torque limiter design is a compensator with a means of vary-
ing pump displacement with pressure in this manner:  The com-
pensator vent port applies pressure to a pin.  The pin moves
against two independently adjustable springs.  A sleeve, sliding
over the pin, opens or closes the vent passage, to control the
compensator pressure.  The sleeve is  connected through a link-
age to the control piston.  As pressure increases, the displace-
ment must reduce, and vice versa, to provide approximate con-
stant torque.

Install  gages on outlet pressure and “V”  capable of measuring
pressure difference to 10 psi, 0,69 bar.  Gages must be ade-
quate for outlet pressure.

Turn compensator adjustment screw out to remove spring load,
then 1/2 turn in.

Turn differential adjustment screw out till there is no contact
with spring, then in 1-1/2 turns.  (Approximately one nut width
exposure of screw thread) 

If the pump contains a servo, hydraulic or electrohydraulic stroker control, test that control first (pg. 64, 68 or 69) then
set the control to give full displacement on the pump.  

CAUTION:

System must contain a relief valve to limit outlet

pressure.  Outlet relief valve should be  set at 500 psi, 34,5 bar.

To test and set compensator function, disable torque limiter in this manner: Back out high pressure flow adjustment
screw (inner) to remove all load.  Turn in high flow pressure adjustment screw (outer) to go solid.  Caution! do not
apply over 10 in. • lb, 1,2 N m torque to avoid damage to internal parts!

Start prime mover with outlet relief set at 500 psi, 34,5 bar.  Apply a load to the pump.

Pump should be at full displacement at 500 psi, 34,5 bar.

Increase outlet pressure until compensator de-strokes pump to zero displacement.  Note minimum compensated pres-
sure versus servo pressure in chart on page 66.  Set compensator to minimum compensated pressure.

Adjust compensator differential spool pressure to 250 psi, 17,2 bar.  This is accomplished by adjusting the differential
screw until the difference in pressure readings between the outlet pressure and compensator vent “V” gages installed
in the compensator cap is 250 psi, 17,2 bar.  Install cover over differential adjustment.
