Attention Should Be Paid To The Installation Of New Hydraulic Pump Of Excavator


After the new hydraulic pump is installed, there are a lot of problems that need to be paid attention to, but many machine friends do not pay attention to this, today sorted out the relevant knowledge, to see what important information is missing by you.

1. Attention should be paid to the operation of the new machine within 3 months of operation

During the operation of the new machine, we should check the operation condition, such as the maintenance of the machine parts, whether the screws are loose, whether the oil temperature is abnormal, whether the hydraulic oil degrades quickly, and check whether the use conditions meet the provisions.

2. Do not add load immediately after starting the hydraulic pump

The hydraulic pump must be implemented for a period of time after starting no load idling (about 10 minutes ~30 minutes), especially when the temperature is very low, it must be through the temperature car process, so that the hydraulic loop circulation is normal and then added to the load, and confirm the operation status.

3. checking the change of oil temperature

Pay attention to check the maximum and minimum oil temperature changes, and find out the relationship between the oil and the external environment temperature, so as to know whether the capacity of the cooler, the capacity of the oil tank and the surrounding conditions, use conditions cooperate with each other, the troubleshooting of the cooling system can also be traced.

4. pay attention to the noise of the hydraulic pump

The new hydraulic pump early wear is less, vulnerable to the influence of bubbles and dust, high-temperature poor lubrication or overloading conditions , will cause adverse consequences , so that the hydraulic pump issued abnormal influence

5. Pay attention to the display value of the checker class.

At any time to observe the hydraulic circuit pressure gauge display value, pressure on and off lights, such as vibration and stability, in order to find out as soon as possible whether the hydraulic circuit function is norm.
