Fault Diagnosis and Troubleshooting of Hydraulic accumulator

Accumulators are dangerous components in hydraulic systems, so special attention should be paid to safety during operation. The diagnosis and troubleshooting of accumulator faults not only includes the diagnosis and troubleshooting of the accumulator itself, but also involves the interweaving of the two. The main tasks of fault diagnosis include: ① determining the nature and severity of the fault. Based on the on-site conditions, determine whether there is a fault, what kind of problem it is (pressure, speed, action, or other), and the severity of the problem (normal, minor, general, or serious) Search for failed components and their locations. Based on symptoms and relevant information, identify the fault point for further troubleshooting. Here, the main focus is to clarify "where the problem lies" Further investigate the initial cause of the malfunction. Such as hydraulic oil pollution, low component reliability, and environmental factors that do not meet requirements. The main focus here is to identify the external causes of the malfunction. ④ Mechanism analysis. Conduct in-depth analysis and exploration of the causal chain of faults to understand the root cause of the problem. ⑤ Predict the trend of fault development. Based on the current status of system wear and deterioration, as well as theoretical and empirical data on speed and component service life, predict the future condition of the accumulator or hydraulic system. Analysis, comparison, statistics, induction, and synthesis to identify regulations.

The above: What are the classifications of energy accumulators?
