The combination of condition monitoring, active maintenance and regular maintenance complement each other
At present, some construction machinery hydraulic systems are equipped with intelligent devices, which have a warning function for certain hidden dangers in the hydraulic system, but are mainly used for monitoring key parameters. Therefore, the inspection and maintenance of the hydraulic system should combine the monitoring results of the intelligent device with the regular inspection and maintenance. Active maintenance can save a lot of workload, improve the reliability and life of equipment, supplemented with appropriate regular routine maintenance, can better ensure that the hydraulic system is in good working condition and equipment status.
Condition monitoring and active maintenance are the future direction of hydraulic equipment maintenance. Key parameters such as particle pollution, water pollution, and temperature of hydraulic oil must be monitored online in real time to prevent accidents and serious damage to equipment life. If the key parameters are found to be abnormal, stop the machine for maintenance at any time, and troubleshoot according to the alarm parameters. Before serious problems occur, timely detection and resolution of problems in the early warning stage is the key to proactive maintenance and a cost-effective solution. Regular maintenance is a necessary means of guaranteeing the state of hydraulic equipment. During the period, check the attachment on the filter screen. If there is too much metal powder, it often indicates that the oil pump is worn or the oil cylinder is scuffed. In this regard, it must be diagnosed and corresponding measures must be taken before it can be turned on. If the filter screen is found to be damaged and dirt has accumulated, it should be replaced in time, and the hydraulic oil should be replaced at the same time if necessary. After the construction machinery has been running for 500 hours, the filter element should be replaced regardless of its condition, because it is difficult to detect the small damage of the filter element with the naked eye, and the filter element should be replaced in advance if it is operated at high temperature for a long time.
After the equipment is used for a long time, the filter should be cleaned, the hydraulic oil tank should be cleaned, the filter element and hydraulic oil should be replaced, and the oil change time for long-term high-temperature operation should be properly advanced. It is the most economical to guide oil change through oil quality detection and analysis, but attention should be paid to the extended use of hydraulic oil, which should be tested every 100 hours, so that the deteriorated hydraulic oil can be found and replaced in time.
After approaching the life cycle of construction machinery originals, the hydraulic system of construction machinery at this time needs to be inspected by professionals for necessary adjustments and maintenance. According to practice, imported hydraulic pumps and hydraulic motors must be overhauled after working for 10,000 hours, otherwise the hydraulic pumps and hydraulic motors may be damaged due to disrepair, which is a fatal damage to the hydraulic system.
