9.6.7. ADJUSTMENT OF HYDRAULIC NON-STOP SECURITIES (Option)
The elements of Grégoire-Besson Varilibre plough can be optionally equipped with Y type hydraulic
Non Stop security.
Behind every element there are two pieces of 3.5 liter capacity hydraulic accumulator. On the front
and rear beam there is 1-1 accumulator. Two accumulators have the same hydraulic circuit.
Inside the accumulator there is a flexible membrane which devices the hydraulic circuit from nitrogen
under the pressure.
Nitrogen compress pressure in accumulator is given, it is displayed and can be modified.

9.6.7.1. Securities base setting
¾ The front accumulator (34) is connected with
security cylinder (one on every plough
bottom).
¾
Hydraulic provision of the security circuit
provides the flexible pipe (36).
¾ During the operation (plough) the pin (37) is
closed and dosing is stopped, so the
hydraulic circuit of the securities becomes
totally separated from the tractor.
The index of the manometer (38) shows the industrial hydraulic pressure of the securities. There is
mode to modify the pressure if we want to increase or decrease the disengagement torque on the
plough blade end.
9.6.7.2.
The increasing of the disengaging torgue of the plough blade end.
If we would like to increase the measured disengaging torque at the end of the plough blade (heavy
soil) in the inner hydraulic circuit of the securities the pressure should be increased.
The pressure can be increased by adding more oil into the system. Oil surplus will be pressed by
nitrogen which is on the other side of the membrane. So greater force is needed at the end of the
plough blade for security elements to operate.
9.6.7.3.
The decreasing of the disengaging torgue of the plough blade end.
If we would like to decrease the measured disengaging torque at the end of the plough blade (light
soil) in the inner hydraulic circuit of the securities the pressure should be decreased.
The pressure can be increased by reducing oil in the hydraulic circuit. As the hydraulic pressure will
be later, the nitrogen which is on the other side of the membrane will expand. So less force is needed
for the operating of the security elements.
