Key points for inflation of bladder type accumulators

A bladder type energy accumulator is a device commonly used to store liquid or gas energy. It consists of a flexible capsule (also known as a membrane) and a container. When inflating a bladder accumulator, there are several key points to note:

Ensure safety: Before inflation, make sure the system is in a stopped state and take appropriate safety measures, such as closing relevant valves, releasing pressure, etc. Avoid inflating the bladder accumulator under high pressure.

Use appropriate pressure: Refer to the manufacturer’s specifications and operating manual to determine the maximum allowable inflation pressure for the bladder accumulator. It is strictly prohibited to exceed the maximum allowable pressure, otherwise it may cause bladder rupture or equipment damage.

Inflatable medium: Determine the inflation medium to be used, usually gas (such as nitrogen) or liquid (such as hydraulic oil). Ensure that the inflation medium is dry, clean, and in compliance with regulatory requirements.

Inflation tool: Use specialized inflation tools to control the inflation process. This is usually a device with a pressure gauge and control valve, which can monitor and adjust the inflation pressure.

Monitoring the inflation process: During the inflation process, closely monitor the pressure changes of the bladder accumulator. Ensure moderate inflation rate and avoid excessive inflation to prevent bag rupture.

Pre inflation pressure: Some bladder type accumulators require pre inflation of a certain pressure to maintain the efficiency of the system during start-up. Ensure that the pre inflation pressure complies with the manufacturer’s recommendations.

Pressure test: After inflation is completed, a pressure test is conducted to ensure that the internal pressure of the bladder accumulator is stable, and no leakage issues are found during the inflation process.

Identification and recording: Mark the inflation date, inflation pressure, and other information on the bladder accumulator, and record these information in the equipment maintenance log for future maintenance and monitoring.

Please note that the inflation and maintenance of bladder accumulators are usually carried out by experienced technicians or professionals. If you are not familiar with the relevant operations, please seek professional assistance to ensure the safety and accuracy of the operation.
