What is the cause of the failure of the hydraulic system? What should be judged from those aspects?
The main content of hydraulic system fault diagnosis is to find out the real cause of the fault according to the characteristics of the fault phenomenon and use various effective means to find out the fault mechanism, effectively eliminate the fault, and accumulate rich experience through summarization to prevent the fault. Provide an effective basis for the occurrence and elimination of similar failures in the future.
The cause of the fault is generally difficult to find, but the causes of the fault under normal circumstances include the following aspects:
1. Human factors: the quality, technical level, management level and working attitude of the operation and maintenance management personnel, whether it is illegal or not, and the maintenance status is good or bad;
2, the quality of the hydraulic equipment and hydraulic components itself: the reasonable degree of the original design, the quality of the original manufacturer's processing, installation and commissioning, the user's commissioning and maintenance status;
3, the analysis of the failure mechanism: for example, long use time, wear, lubrication and sealing mechanism, material properties and failure modes, aging deterioration of hydraulic oil, pollution and other aspects.
Fault management is a meticulous, complex and consistent work that can be effective. The main practices for fault management are as follows:
1. Do a good job in propaganda and education, mobilize all members to participate in the fault management mechanism, establish a fault management system, implement regional maintenance responsibility system and regional guarantee limit indicators, unify responsibility, rights and interests, assess and evaluate, and reward and punishment clearly;
2. Start from the basic work, closely combine the production requirements and equipment status, determine the equipment failure management focus, and take measures to reduce equipment failure. It is necessary to classify equipment that has a large impact on production, is prone to failure, has a long downtime or large loss, and is difficult to repair, and is strictly controlled;
3. Do a good job of equipment failure record. The fault record is the basis for implementing fault management, fault analysis and processing. Inspection records, maintenance diaries, and sound original records must be established. If conditions permit, you should start the inspection and carefully fill out the “equipment failure repair orderâ€;
4. Equipment fault information collected from various sources can be divided into units and equipment categories for statistical analysis, analysis, calculation of fault frequency and average fault interval of various types of equipment. Analyze the fault dynamics and repeated fault causes of a single device, find out the fault occurrence rules, and adopt corresponding policies;
5. Adopt monitoring instruments and diagnostic techniques to accurately grasp the actual characteristics of key equipment, find fault signs and deterioration information as early as possible, and realize maintenance based on state detection;
6. Establish a fault finding logic program. To this end, it is necessary to compile common fault phenomena, analysis steps, causes, and troubleshooting methods to make fault finding logic analysis program diagrams, causal maps, etc., which not only can improve work efficiency;
7. According to the fault phenomenon, the cause of the fault, the type, the characteristics of different equipment, take different countermeasures, and establish a fault management and equipment maintenance management system suitable for the unit.
