Usage Patterns Of Tractor Hydraulic System For Driving Of Operated Parts And Other Elements Of Unitized Hydraulically Operated Machines And Units - Belarus 1822.3 Operator's Manual

5.5 Usage patterns of tractor hydraulic system for driving of operated parts
and other elements of unitized hydraulically operated machines and units
Hydraulic control system for implements mounted on tractor "BELARUS-
1822.3/1822 .3/2022.3/2022 .3" provides means for oil extraction for operation of the im-
plements coupled. Meanwhile the following variants are possible:
- oil extraction by unilateral and bidirectional hydraulic cylinders (hereinafter referred
to as hydraulic cylinders);
- replenishment of oil volume in a tank caused by flooding of cylinder and fittings
chambers shall be assured after trial performance of the hydraulic system of the tractor
with an implement;
- oil extraction for hydraulic motors drives (hereinafter referred to as hydromotors).
While operating hydraulically operated machines with hydraulic motor its drain pipe
must be connected to a special tractor output to ensure free oil drain into the tank by-
passing integrated unit.
ATTENTION: FOR ENSURING OF THE REQUIRED ROTATIONAL SPEED OF
THE HYDROMOTOR OF THE IMPLEMENTS COUPLED CERTAIN OIL SUPPLY IS
NECESSARY. HYDRAULIC FLUID FEEDING ON THE TRACTOR "BELARUS-
1822.3/1822 .3/2022.3/2022 .3" DEPENDS ON THE ENGINE RPM, THEREFORE IM-
PLEMENT HYDRAULIC DRIVE MUST BE EQUIPPED WITH ITS OWN FLOW ADJUST-
ING VALVE!
In case of use of outputs of tractor hydraulic system for maintenance of the imple-
ment coupled, it is necessary to ensure the required volume of oil in a tank. Extraction of
oil by cylinders of the implement coupled should not exceed 10 liters.
Excessive oil extraction during coupling causes load increase on hydraulic system
of a tractor. At long-term use of a hydraulic drive it is necessary to track a temperature
range in a hydraulic system.
Level check in a tractor hydraulic tank and its refill shall be carried out with retracted
cylinder of the implements coupled. You must not fill in the oil when working attachments
of the implement coupled are in raised position as it can result in the tank overflow and
blow-out of elements of a hydraulic drive by the excessive oil being displaced from cylin-
ders at the subsequent landing of the working attachments.
