Fault diagnosis and elimination of product HYDAC accumulator

HYDAC accumulator fault diagnosis and elimination
The maintenance process of the Hedak hydac accumulator HYDAC accumulator is leak-proof during use, and the air bag should be inspected regularly for air tightness and other aspects. Therefore, daily inspection and maintenance are essential. Daily inspections use simple methods such as visual, auditory, and hand-touching and instrumentation to check the appearance and condition. When inspecting, it is necessary to check the parts as well as the whole equipment. The abnormal conditions found during the inspection shall be emergency treatment for obstructing the continued operation of the HYDAC accumulator; others shall be carefully observed and recorded by the rain, and shall be resolved by regular maintenance. Some damaged parts also need to be replaced in time. Active maintenance is a new equipment management theory proposed in the international market in recent years after fault repair, preventive maintenance and state maintenance. It is defined as: repairing the root-cause parameters that cause equipment damage, thus effectively preventing the occurrence of failures and extending the service life of the equipment. Proactive maintenance is a measure taken against the root cause before equipment wears out, effectively controlling wear and failure, thereby significantly extending the repair cycle. Active maintenance not only guarantees the operation of hydraulic equipment and components, but also greatly reduces maintenance costs.
HYDAC accumulator fault diagnosis and elimination
HYDAC accumulator fault diagnosis and elimination, including the diagnosis and elimination of the HYDAC accumulator itself fault, and the fault diagnosis and elimination of the hydraulic system where the HYDAC accumulator is located, the two are intertwined. The main work of fault diagnosis is: 1 determine the nature and severity of the fault. According to the site conditions, determine whether there is a fault, what is the nature of the problem (pressure, speed, action or other), the severity of the problem (normal, minor, general, or severe). 2 Find the failed component and the failed position. According to the symptoms and related information, find out the point of failure, in order to further troubleshoot, here mainly to find out "where the problem is." 3 Further find the initial cause of the failure. Such as hydraulic oil pollution, low component reliability, environmental factors are not required. Here is mainly to find out the external cause of the fault. 4 mechanism analysis. In-depth analysis and discussion of the causal chain of failures, to understand the ins and outs of the problem. 5 predict the trend of fault development. The future status of the accumulator or hydraulic system is predicted based on the current state of wear and degradation of the system and the theoretical and empirical data on the service life of the components. Analyze, compare, count, summarize, and synthesize to find out the law.
