Hydraulic pump installation should pay attention to the matter

First, the operation of the new machine should pay attention to the operation within three months during the operation of the new machine, should grasp the operational status checks, such as machine maintenance, screws are loose, the oil temperature is not abnormal increase, the hydraulic oil is very Fast deterioration, check the conditions of use compliance and so on. Second, do not immediately after the start of the hydraulic pump to increase the load After the start of the hydraulic pump to be implemented for 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 Add to the load and confirm the operation status. Third, the observed changes in oil temperature Attention to check the highest and lowest oil temperature changes, and found the relationship between oil temperature and ambient temperature, so you can know the cooler capacity, storage tank capacity and the surrounding conditions, the conditions of use complement each other on the cooling system The troubleshooting is also only traceable. Fourth, pay attention to the noise of the hydraulic pump New hydraulic pump less wear and tear early, vulnerable to bubbles and dust, poor lubrication at high temperatures or the use of conditions such as overload, will cause adverse consequences, the hydraulic pump issued an abnormal impact. Fifth, pay attention to check the display value of the class of instruments at any time observe the pressure gauge hydraulic circuit shows the value of the pressure switch lights and other vibration conditions and stability to early detection of the role of the hydraulic circuit is normal. Sixth, pay attention to observe the mechanical action (for 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 in various conditions of use. Seven, pay attention to the adjustment within the valve Fully understand the use of pressure control valve, flow control valve and directional control valve, the adjustment range and limit to be paid special attention to, otherwise adjustment error not only damage the machinery, but also pose a threat to safety. Eight, check the status of the filter on the loop filter should be regularly removed and check the status of the filter and the net adsorption of dirt, analysis of quality, quantity and size, so that you can observe the degree of pollution in the circuit, even based on this Inferred sources of pollution. Nine, regular inspection of 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. Ten, pay attention to the piping part of the leakage Hydraulic equipment piping good or bad, after running for a period of time can be seen, the prosecution is oil spills, pipe is loose. Eleven, always pay attention to the abnormal phenomenon of abnormal sound, vibration or abnormal signal monitoring system, there must be its own reasons, when an unusual phenomenon, 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.
