On-site inspection and information collection<\/h2>\n<p>Technicians should inspect the equipment directly on site and communicate with operators to collect information about:<\/p>\n<ul>\n<li>Operating conditions<\/li>\n<li>Abnormal phenomena before and after the failure<\/li>\n<li>History of similar faults and previous solutions<\/li>\n<\/ul>\n<p>This information provides an important basis for narrowing down the possible causes of the fault.<\/p>\n<h2>2. Operational observation<\/h2>\n<p>If the equipment can be safely tested, technicians should:<\/p>\n<ul>\n<li>Start the system<\/li>\n<li>Perform relevant control operations<\/li>\n<li>Observe fault symptoms<\/li>\n<li>Monitor changes in operating parameters<\/li>\n<\/ul>\n<p>Comparing actual data with operator feedback helps accurately assess the system condition.<\/p>\n<h2>3. Reviewing technical documents and diagrams<\/h2>\n<p>It is necessary to check:<\/p>\n<ul>\n<li>Hydraulic system schematic diagrams<\/li>\n<li>Electrical control diagrams<\/li>\n<li>Equipment technical documentation<\/li>\n<\/ul>\n<p>This helps clarify the system structure, the function of each component, installation positions, and potential failure points. Reviewing maintenance history can also help identify recurring issues.<\/p>\n<h2>4. Fault analysis and diagnosis<\/h2>\n<p>Based on the operating principles and collected data, technicians should:<\/p>\n<ul>\n<li>Formulate hypotheses about possible causes<\/li>\n<li>Perform step-by-step inspection and measurements<\/li>\n<li>Adjust conclusions until the root cause is clearly identified<\/li>\n<\/ul>\n<p>This is the key stage in servo hydraulic system troubleshooting.<\/p>\n<h2>5. Repair implementation according to technical procedures<\/h2>\n<p>Repair work should follow the principle:<\/p>\n<ul>\n<li>Check externally before internally<\/li>\n<li>Adjust before disassemble.<\/li>\n<\/ul>\n<p>This approach minimizes risks, prevents additional damage, and ensures effective long-term maintenance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>During operation, servo hydraulic systems may experience various types of faults, making hydraulic system fault diagnosis a complex technical task.
