CHAPTER III MACHINE OPERATION

2.5 HYDRAULIC SYSTEM

2.5.1 IMPLEMENT HYDRAULIC SYSTEM

2.5.1.1 Implement hydraulic system is used to control the action of the bucket, including oil tanks,
implement pump, the multiple way valve, the boom cylinder, the tilt cylinders, the leveling valve, oil tubes
and other components.

2.5.1.2 When the working device does not work, the hydraulic oil from the implement pump flows
to the implement distribution valve, then the hydraulic oil flows through chamber and flows back to the oil
chamber and oil tank.

2.5.1.3 When you shovel materials, dump materials, moving the right handle, the oil from the
implement pump flows through the distribution valve into the rear or front chamber of the bucket cylinder.
This causes the bucket to tilt up or down. When you raise or lower the lift arm, moving the left handle, the
oil from the implement pump flows through the distribution valve into the lower or upper chamber of lift
boom cylinder. This causes the lift and the bucket to raise or lower.

2.5.1.4 When the external load exceeds the raising or tilting up capacity of the system, or the piston
of boom cylinder reaches the end of the cylinder (the piston of the bucket cylinder reaches the front end
of the cylinder). When the system pressure goes up to the set point, the pressure oil opens the escape
valve to overflow and unload. The pressure oil flows through the distribution valve back to the oil tank.

2.5.1.5 When the oil pressure of the bucket cylinder front chamber is higher than the set pressure of
the double-acting escape valve in the front chamber multiple reversal valve, the pressure oil opens the
escape valve to overflow and unload. The pressure oil flows through the distribution valve back to the oil
tank. The implement oil from the pump flows through the distribution valve into the upper and lower
chamber of the boom cylinder and connects the fuel tank at the moment, the oil pressure in the upper
and lower chamber of the cylinder is low. The bucket can float freely caused by its own weight and can
work close to the ground.

2.5.1.6 The implement pump is gear type. The implement and traveling pumps are coaxial with the
engine, but the traveling pump is piston type.

2.5.2 TRAVEL HYDRAULIC SYSTEM


Travel hydraulic system is used for controlling the travel of the machine, including the oil tank, the
variable piston pump, the travel motor, unblocking solenoid valve, oil tubes and other components.

2.5.2.1 The variable piston pump

The variable piston pump is connected to the engine by the coupling. It provides driving force for
the travel system.

6.3.2 The accumulator with the end pillar broke can not be supplied, find the causes and then replace.

6.3.3 Accumulator with the white electrical eyes, make sure that whether caused by the jam of the
green ball inside the electrical eye or not, if that , could shake the ball lightly. Otherwise the white
electrical eyes caused by the low level of the accumulate electrolyte, or it is dry, displace the accumulate.

6.3.4 The end pillar covered with skin oxidation, before supplying, clean it and remove the skin
oxidation.

6.4 BATTERY CHARGING


6.4.1 If do the incorrect operation to the accumulator in the condition of charging, otherwise leading to
explode; please operate it according to the processing regulation of the accumulator and the relevant
regulations in the user manual, the following precautions must be obeyed:

6.4.2 In the process of charging and testing the accumulator, the combination of oxygen and hydrogen

is discharged from the venthole, when the consistency of hydrogen in the air beyond 4 , exploding will
happened with fire, sparkle or high-heating; as a result, during the process of charging, it should be
ventilated and no smoking preventing sparkle and fire.

6.4.3 Accumulator should be charged in the normal temperature, and please wear the safety glasses
during the recharging operation.

6.4.4 Keep the accumulator on the flat ground, and the incline is less than 40°.

6.4.5 In the process of accumulator charging, connect the positive (+) of generator to the positive (+) of
accumulator, and then connect the negative (-) of generator to the negative (-) of accumulator, avoid
charge reversely.

6.4.6 During charging the accumulator, we should keep the temperature of electrolyte less than 45°C,
in order to avoid the electrolyte spouting out caused by high temperature.

At the end of recharging, the oxygen and hydrogen produced by electrolyte leads to the loss of water,
and the higher of the charge voltage is, the more loss of water. As the free-maintenance accumulator
does not need to watering, so we recommend recharging with constant voltage instead of constant
current.
