Key points for inflation of diaphragm accumulator

Diaphragm accumulator is a common hydraulic system component used to store pressure energy. When using an inflatable diaphragm accumulator, the following points should be noted:

Safe operation: Before inflation, ensure that the hydraulic system is in a safe state, all related pressures have been released, and the system is in a stopped state. Ensure a safe working environment and avoid using excessive pressure for inflation.

Pressure limit: Refer to the technical manual or manufacturer’s guide of the diaphragm accumulator to understand the maximum allowable pressure during inflation. It is strictly prohibited to exceed the specified pressure range to avoid damaging the accumulator or posing safety risks.

Inflation tools: Use specially designed inflation tools, such as manual or automatic inflation pumps, to ensure the inflation process is controllable. These tools are usually equipped with pressure gauges and safety valves to ensure real-time monitoring of pressure during inflation and to avoid excessive pressure.

Inflatable medium: Typically, diaphragm accumulators use gas (such as nitrogen) as the inflating medium. Ensure that the inflation medium has high purity, dryness, and meets the specifications of the hydraulic system.

Inflation process control: During the inflation process, gradually increase the pressure to avoid sudden or rapid inflation, in order to avoid adverse effects on the diaphragm accumulator. Gradual pressurization, pauses, and inspections can be used to ensure a smooth inflation process.

Pressure test: After inflation is completed, perform a pressure test to ensure that the pressure inside the diaphragm accumulator meets expectations and there are no leakage issues. Use a pressure gauge or other testing equipment for testing and record the test results.

Inflation label: After inflation is completed, mark the inflation date, inflation pressure, and other information on the diaphragm accumulator. This helps to track the usage of the accumulator and perform maintenance or replacement when needed.

Regular inspection: Regularly check the inflation status of the diaphragm accumulator to ensure stable pressure and promptly handle any abnormal situations. Regular maintenance and inspection are the key to ensuring the safe and reliable operation of diaphragm accumulators.

In summary, the inflation process of diaphragm accumulators requires careful operation, following the manufacturer’s guidelines and safety regulations to ensure safe and reliable operation of the hydraulic system.
