Liugong excavator parts reveal ten precautions after replacing the hydraulic pump with the excavator

Release date:2018-11-02

Many Liugong excavator parts repairers and excavator drivers will find that after the excavator replaces the hydraulic pump, the machine is often not 100% normal. Maybe it will be problematic soon after work. In fact, not only the hydraulic pump, the excavator repair replaces many Some parts are the same. There are many details after the replacement process and replacement. It is worthwhile to pay attention to the merits. The following are the ten points given by the Liugong excavator parts for the replacement of the hydraulic pump.

Liugong hydraulic pump




(1) Pay attention to the appearance value of the meter class


At any time, investigate the pressure gauge display value of the hydraulic circuit, the oscillation view and stability of the pressure switch, etc。, to find out whether the hydraulic circuit is normal or not。



(2) Investigate oil temperature changes


Pay attention to the change of the highest and lowest oil temperature, and find out the relationship between the ambient temperature of the oil and the ambient temperature。 So you can know whether the capacity of the cooler, the capacity of the storage tank and the surrounding conditions, the application conditions match, and the problem of the cooling system is eliminated。 Traces can be followed。



(3) Do not immediately add the load to the hydraulic pump after starting it。


After the hydraulic pump is started, it must be run for a period of time without load (about 10 minutes to 30 minutes). When the temperature is very low, it is necessary to go through the warm-up process to make the hydraulic circuit cycle normally and then add the load, and recognize the working condition.




(4) Keep an eye on the discovery of anomalies at any time


Abnormal sounds, oscillations, or abnormal signals of the supervisory system must have their causes. When an abnormal phenomenon is found, immediately find the circuit diagram. According to the figure, be careful to investigate whether the anomaly is a temporary fault. Evaluation does not require parking processing. The reasons for abnormality may be included in the pressure, load, temperature, time, start-up, and suspension. Normally, the discussion should be analyzed item by item.




(5) Pay attention to the operation of the machine (about the modified pump)


Inappropriate planning of the hydraulic circuit or poor manufacturing of components is not easy to find at the beginning of the application phase, so special attention should be paid to the behaviors that appear under various operating conditions.



(6) Pay attention to the noise of the hydraulic pump


The new hydraulic pump has less initial wear and is easily affected by air bubbles and dust. If the temperature is poor at high temperature or the conditions are excessive, the hydraulic pump will cause abnormal effects.




(7) Regularly check the change of hydraulic oil


Look at the changes in hydraulic oil deterioration, discoloration and pollution level every one or two months to ensure the normality of the hydraulic transmission preface。



(8) Pay attention to the adjustments in each valve


Fully understand the use of pressure control valves, flow control valves and directional control valves, pay special attention to the adjustment range and limits, otherwise adjustment errors will not only damage the machinery, but also pose a threat to safety。




(9) View the status of the filter


The filter in the circuit should be taken out regularly, and the condition of the filter and the dirt adsorbed on the net should be checked, and the quality, quantity and size of the filter should be analyzed, so that the degree of pollution in the circuit can be investigated, and the Liugong excavator parts can even be inferred accordingly. The location of the pollution.


(10) Pay attention to part of the piping leakage


Whether the piping of the hydraulic equipment is good or not can be seen after working for a while, to see if there is oil leakage and whether the piping is loose.



甘肃快3走势图(11) Pay attention to the work situation within three months of the new machine work


During the working period of the new machine, you should check the work status, such as the maintenance of the machine parts, whether the screws are loose, whether the oil temperature is abnormally rising, whether the hydraulic oil is deteriorated quickly, and whether the operating conditions are in compliance with the regulations.
