The use and maintenance of the accumulator mainly includes the installation and maintenance, troubleshooting and repair of the accumulator.

The installation of the accumulator includes inspection, installation, nitrogen charging, etc. before installation. Correct installation, fixation and inflation are important conditions for the normal operation and lease of the accumulator. The measurement of parameters and the correct use of various tools and instruments cannot be ignored.

During the use of the accumulator, it is required to prevent vibration, high temperature, pollution and leakage. The air tightness and other aspects of the air bag shall be checked regularly. Therefore, daily inspection and maintenance are indispensable. Daily inspection refers to visual, auditory, hand touch and instrument inspection. During the inspection, both local parts and the whole equipment shall be inspected. If abnormal conditions are found during the inspection, emergency treatment shall be carried out for those hindering the continuous operation of the accumulator; Others shall be carefully observed and recorded. It shall be solved during regular maintenance. Some damaged parts also need to be replaced in time. Active maintenance is a new equipment management theory put forward in recent years after fault maintenance, preventive maintenance and condition based maintenance. His definition is to extend the service life of equipment. Active maintenance is to take measures against the root causes of equipment wear before it is worn, effectively control the occurrence of wear and failure, thus greatly extending the repair cycle. Active maintenance not only guarantees reliable operation of hydraulic equipment and components, but also greatly reduces maintenance costs.

Accumulator is a dangerous part in hydraulic system, so pay special attention to safety during operation.

The fault diagnosis and removal of the accumulator not only includes the diagnosis and removal of the accumulator itself, but also involves the fault diagnosis and removal of the hydraulic system where the accumulator is located. The two are intertwined. The main work of fault diagnosis includes: ① Determine the nature and severity of the fault. Judge 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) according to the site conditions. ② Find the failure element and failure location. According to the symptoms and relevant information, find out the fault point so as to further eliminate the fault. Here, it is mainly to find out "where the problem is". ③ Further find out the initial cause of the fault. For example, the hydraulic oil is polluted, the reliability of components is low, and the environmental factors do not meet the requirements. It is important to find out the external cause of the fault. ④ Mechanism analysis. The cause and effect chain of the fault is analyzed and discussed in depth to clarify the cause and effect of the problem. ⑤ Prediction of fault development trend. According to the current situation of system wear and deterioration and the theoretical and empirical data of speed and component service life, predict the future condition of the accumulator or hydraulic system. Analysis, comparison, statistics, induction and synthesis to find out the rules.
