Construction machinery to replace the new hydraulic pump should pay attention to what issues? 1, always pay attention to the discovery of anomalies: abnormal sound, vibration or abnormal signal monitoring system, there must be its own reason, an abnormal phenomenon was found, immediately find the circuit diagram, according to every possible means, carefully observe whether the abnormal phenomenon caused by a temporary error . Assessment need not need parking treatment. All pressure, load, temperature, time, start, stop when it includes the possible causes of abnormal phenomena. Usually that should be one by one analysis and discussion. 2, do not immediately after the start of the hydraulic pump to increase the load: the hydraulic pump to be carried out after the start of a period of no-load idling (about 10 minutes to 30 minutes), especially when the temperature is very low, but also by the car process, the hydraulic circuit cycle Normally added to the load, and confirm the operation status. 3, observe the oil temperature changes: pay attention to check the maximum and minimum oil temperature changes, and found the relationship between oil temperature and ambient temperature, so you can know the cooler capacity, storage tank capacity and whether the surrounding conditions, the use of conditions with each other, the cooling System troubleshooting also has its own way. 4, pay attention to the noise of the hydraulic pump: The new hydraulic pump less wear and tear, susceptible to the impact of bubbles and dust, high temperature lubrication, poor conditions or conditions of use, will cause adverse consequences, the hydraulic pump issued an abnormal effect. 5, pay attention to check the display value of the meter class: at any time to observe the pressure gauge shows the value of the hydraulic circuit, pressure switch lights and other vibration conditions and stability to early detection of the hydraulic circuit is normal. 6, pay attention to observe the mechanical action (for the modified pump): improper hydraulic circuit design or component manufacturing poor, not easy to find in the initial use phase, it should pay special attention to the operating conditions revealed under various conditions of use. 7, pay attention to the adjustment of the valve: a full understanding of the pressure control valve, flow control valve and directional control valve use, the adjustment range and limit to be paid special attention to, or adjustment error not only damage the machinery, but also pose a threat to safety. 8, check the status of the filter: The filter should be regularly removed from the circuit to clean up, and check the status of the filter and the network of adsorbed dirt, analysis of quality, quantity and size, so you can observe the degree of pollution in the loop, This concludes that the source of the pollution. 9, regularly check the hydraulic oil changes: every one or two months, check the analysis of hydraulic oil deterioration, discoloration and pollution changes in order to ensure the normal hydraulic transmission medium. 10, pay attention to the piping part of the leak: hydraulic device piping good or bad, after running for a period of time can be seen, the prosecution is oil spills, plumbing is loose. 11, the new machine should pay attention to the operation within three months operating conditions: during the new machine operation, should grasp the operational status checks, such as machine maintenance, screws are loose, the oil temperature is not abnormal increase, the hydraulic oil is whether Quickly deteriorated, check the conditions of use compliance and so on.
