Steps to Take When Your Accumulator Fails to Retain Pressure

When your accumulator is unable to maintain pressure, the following steps can be taken for troubleshooting and repair:
Preliminary inspection:
Confirm that there is indeed pressure loss in the accumulator, and compare the current pressure with the normal operating pressure range.
Check for obvious damage, leakage, or deformation on the outside of the accumulator.
Check if all pipes, valves, and joints connected to the accumulator are tight and there are no leaks.
Diagnose using testing equipment:
Use a pressure gauge to check the actual pressure of the accumulator and observe if it continues to decrease.
If possible, use leak detection agents to locate potential leak points.
Check internal components:
If external inspection fails to identify the problem, consider inspecting the internal components of the accumulator, such as the piston, seals, and diaphragm.
Note that for certain types of accumulators (such as diaphragm type), special tools or skills may be required to inspect internal components.
Repair leaks or replace components:
If a leak is found, immediately repair or replace the damaged components. This may include replacing the O-ring seal, repairing the nitrogen diaphragm, or replacing the entire accumulator.
For the situation of nitrogen diaphragm damage, the lack of nitrogen can be determined by observing the compressibility of the detection pin, and then determining whether the diaphragm is damaged.
When replacing parts, make sure to use replacement parts that are compatible with the original parts and install them according to the manufacturer’s guidelines.
Train operators to increase their awareness of potential issues and preventive measures.
Use appropriate lubricants to reduce friction and wear, and extend the service life of the accumulator.
Please note that the above steps are general guidance, and specific troubleshooting and repair methods may vary depending on the type, manufacturer, and specific application of the accumulator. T
