Key points for using piston accumulator

A piston accumulator is a common hydraulic system component used to store pressure energy. Here are some key points when using a piston accumulator:

Safe operation: Before using the piston accumulator, ensure that the hydraulic system is in a safe state, all related pressures have been released, and the system is in a stopped state. Avoid operating under high pressure to avoid accidental injury or equipment damage.

Installation location: Choose an appropriate installation location to ensure that the piston accumulator can effectively store pressure and will not be damaged or interfered with by external objects.

Pressure limit: Understand the maximum working pressure of the piston accumulator and ensure that it does not exceed its rated pressure range. Exceeding the rated pressure may cause the accumulator to rupture or damage other system components.

Inflatable medium: Typically, piston accumulators use gas (such as nitrogen) as the inflating medium. Ensure high purity, dryness, and compliance with system specifications of the inflation medium.

Inflation process: Before inflation, ensure that the piston accumulator is in the released state. Use appropriate inflation tools (such as manual or automatic inflation pumps) to gradually increase the inflation pressure to avoid sudden or rapid inflation.

Pressure monitoring: During the inflation process, use tools such as pressure gauges to monitor the pressure changes inside the piston accumulator. Ensure stable inflation pressure and stop inflation after reaching the predetermined pressure.

Testing and calibration: After inflation is completed, a pressure test is conducted to verify whether the working pressure of the piston accumulator meets the requirements. If necessary, calibrate the inflation pressure based on the test results.

Regular inspection and maintenance: Regularly check the inflation status of the piston accumulator to ensure stable pressure, and carry out regular maintenance and upkeep work. This includes cleaning, lubrication, and replacing seals.

Avoid overuse: Avoid frequent use of piston accumulators and try to avoid damage caused by excessive pressure or temperature.

Safety signs: Mark the inflation date, inflation pressure, and other information on the piston accumulator, and regularly update and record this information for future tracking and maintenance.

In summary, careful operation is required when using piston accumulators, following the manufacturer’s guidelines and safety regulations to ensure safe and reliable operation of the hydraulic system.
