CHAPTER III – DESCRIPTION OF PLOUGH – Page 11
The principle of the work flow limiting pulley :
Inside the pulley (41) there is a plane spring-washer (39) which fastens circlips (40).
When the plough bottom disengages, the oil flowing from the cylinder int he whole length catche
s
the spring-washer circlip. The spring-wacher provides the oil flowing across sevel holes in the
pulley.
After the overcoming the obstacle hydraulic system pressure constrains the oil into the se
curity
cylinder (42)
. The oil going back into the cylinder presses down the spring-washer ont he bottom
of the pulley. Only the middle hole let the oil flow back with the help of it its flowing be
comes slow.
IMPORTANT: Pay attention on the d
irection during the mounting of the pulley (41) into the cylinder
(42). The circlip must look outside.
ATTENTION : The pressure must be decreased
to 0 bar before starting any interference.
Follow the security instructions (chapters «General security instructions» and «Greasing
and maintenance») If it is necessary ask the help from the GRÉGOIRE-BESSON dealer.
3.9.3 Accumulators
The mounted standard accumulators are used with industrial 100 bar pressure adjustment. The
plough optionally can be mounted with 150 bar accumulators.
Externally th
ere is no difference between two accumulators, the nitrogen adjustment can be seen
ont he label or it is chiseled on the accumulator.
