The problems that should be paid attention to after the hydraulic pump is installed:
(1) Pay attention to the operation status within three months of the operation of the new machine. During the operation of the new machine, check the operation status, such as the maintenance of the machine parts, whether the screws are loose, whether the oil temperature is abnormally rising, and whether the hydraulic oil is Deteriorate quickly, check whether the conditions of use meet the requirements, etc.
(2) Do not immediately add the hydraulic pump after starting the hydraulic pump. After starting, it must be carried out for a period of time without load idling (about 10 minutes to 30 minutes). Especially when the temperature is very low, it is necessary to pass the warming process to make the hydraulic circuit circulate. Normally add the load and confirm the operation.
(3) Observe the oil temperature change, check the maximum and minimum oil temperature changes, and find out the relationship between the oil temperature and the external environment temperature, so as to know whether the cooler capacity, the storage tank capacity and the surrounding conditions, the use conditions match, and the cooling The troubleshooting of the system is also traceable.
(4) Pay attention to the noise of the hydraulic pump The new hydraulic pump has low initial wear and is easily affected by air bubbles and dust. If the lubrication is poor at high temperature or the conditions are too high, the hydraulic pump will cause abnormal effects.
(5) Pay attention to the display value of the checker class. Observe the pressure gauge display value of the hydraulic circuit, the vibration condition and stability of the pressure switch lamp at any time, and find out whether the hydraulic circuit is working properly as early as possible.
(6) Pay attention to the movement of the machine (for the modified pump)
Improper design of the hydraulic circuit or poor manufacturing of the components is not easy to find in the initial use phase, so special attention should be paid to the operating states that appear under various conditions of use.
(7) Pay attention to the adjustment in each valve. Fully understand the use of pressure control valve, flow control valve and directional control valve. Pay special attention to the adjustment range and limit. Otherwise, the adjustment error will not only damage the machine but also pose a threat to safety.
(8) Checking the state of the filter. The filter in the circuit should be periodically removed and cleaned, and the state of the filter and the dirt adsorbed on the net should be checked to analyze the quality, quantity and size. This can observe the degree of pollution in the circuit, and even This infers the source of the pollution.
(9) Regularly check the change of hydraulic oil. Check the analysis of hydraulic oil deterioration, discoloration and pollution level every one or two months to ensure the normality of the hydraulic transmission medium.
(10) Pay attention to the leakage of the piping. Whether the piping of the hydraulic unit is good or not can be seen after running for a period of time. Check whether the oil leaks and the piping is loose.
(11) Always pay attention to the abnormal phenomenon, abnormal sound, vibration or monitoring system abnormal signal, etc., there must be a reason, when an abnormal phenomenon is found, immediately find the circuit diagram, according to the diagram, carefully observe whether the abnormal phenomenon is caused by a temporary error . The assessment does not require parking. The pressure, load, temperature, time, start-up, and stop time all contain the possibility of abnormality. Usually, it should be analyzed item by item.
