Hitachi ex60 hydraulic pump maintenance instructions
1. When the excavator is working and the pump abnormal sound, the excavator vibrates, or the computer board displays a fault code or an alarm, be sure to stop the machine to check whether it is caused by the hitachi ex60 hydraulic pump failure.
2. When the operating environment temperature of the excavator is very low, it is necessary to run the excavator idling for more than 10 minutes after the excavator is started. After the temperature of the excavator rises, load the excavator to ensure that the hydraulic pump of the excavator works normally.
3. The excavator must always pay attention to whether the hydraulic oil temperature of the excavator is too high? Is the water temperature of the excavator too high?

4. When the hitachi ex60 hydraulic pump of the excavator is first used, pay attention to whether the pump has abnormal noise? Because it is easily affected by air bubbles and dust at the beginning of operation, poor lubrication at high temperature or overloading of conditions, etc., make the hydraulic pump emit abnormal sound.
5. Pay attention to the displayed value of the pressure gauge of the hydraulic circuit of the excavator at any time.
6. Understand the function of each valve inside the hitachi ex60 hydraulic pump system of the excavator.
7. When replacing the pump, pay attention to whether each filter screen in the oil circuit in the hydraulic system of the excavator is blocked?
8. The excavator regularly checks the use of hydraulic oil. Basically every one or two months, it is necessary to analyze whether the hydraulic oil of the excavator has deteriorated? Is there any discoloration? Is it polluted.
9. Pay attention to whether the piping of the hydraulic device is working normally? After running for a period of time, check whether there is oil leakage and whether the piping is loose?
10. During the operation period of the new machine, the excavator should grasp the operation status inspection, such as the maintenance of the machine parts, whether the screws are loose, whether the oil temperature rises abnormally, whether the hydraulic oil deteriorates quickly, and check whether the use conditions meet the regulations Wait.
The hydraulic pumps of excavators are mostly swash plate variable double hydraulic pumps. The so-called variable pump means that the displacement of the pump can be changed. It changes the stroke of the plunger by changing the swing angle of the swash plate to realize the change of the oil volume discharged by the pump. The advantage of the variable pump is that within the adjustment range, the power of the engine can be fully utilized to achieve the effect of high efficiency and energy saving, but its structure and manufacturing process are complicated.
There are two ways to choose and install the hydraulic pump: series installation and parallel installation. Series pumps and parallel pumps are both types of axial piston pumps. The main difference is that the structure is different. From the perspective of displacement, it can be divided into quantitative pumps and variable pumps. Most of the excavators are variable pumps. Here we only talk about variable pumps.
