CHAPTER III – DESCRIPTION OF PLOUGH – Page 9
Every cylinder is conne
cted with the same hydraulic accumulator (32).
The task of the hydraulic accumulator (32) to provide suitable elasticity when the part impacts the
obstacle and deflects around the axle-journal.
Inside the accumulator there is a flexible membrane (33) which separates the hydraulic olaj (34)
coming from cylinders, from nitrogen placed under the pressure (35). The characteristic of the gas
nitrogen is that it can be compressed. The gas is compressed in the plant under the certain pressure
and cannot be changed.
Anti-bouncing affect can be got by hydraulic oil pressure (34).
With the injection and the extraction of the oil into and out of the security hydraulic circ
uit the
flexible membran becomes deformed, In this f
unction nitrogen more or less co
agulates.
When the plough head comes across the obstacle the turning of the mechanic disen
gaging
part causes
compression. Then the surplus of the oil is abso
rbed by the accumulator
producing the bouncing.
After the overcoming the obstacle the over pressure in the accumulator gets back in
to the
cylinder and makes the plough head
s go back on
the soil.
The adjustment of the se
curities disengaging power is changeable. It is performed with the help of the
filler (36) and can be adjusted by manometer (37).
If the varia
bly possibilities of the manometer are not enough,
optionally there are two ways to increase the security
disengaging power:
With the increasing
of the security cylinder
diameter,
With the usage of the industrial nitrogen
adjustment accumulator.
