Use of nitrogen charging tools for accumulators

The accumulator nitrogen charging tool is a device specifically designed to charge nitrogen into the accumulator, ensuring that the accumulator can reach the predetermined gas pressure. The following are the general steps for using an accumulator nitrogen charging tool:

Preparation work:

Ensure that you have understood the requirements of the hydraulic system, including the required nitrogen charging pressure and accumulator specifications.

Obtain nitrogen charging tools suitable for the type of accumulator used.

Safety measures:

Before carrying out any operations, please ensure to wear appropriate personal protective equipment, such as gloves and eye protection.

Please ensure the safety of the operating environment and prevent any potential hazards.

Connection tool:

Connect the connection part of the nitrogen charging tool of the accumulator to the nitrogen charging port on the accumulator. Ensure that the connections are tight to prevent gas leakage.

Nitrogen filling:

Start the accumulator nitrogen charging tool and set the required nitrogen charging pressure according to the specifications of the hydraulic system. Tools usually have pressure control and display functions.


During the nitrogen charging process, pay attention to monitoring the pressure of the accumulator. Ensure that the pressure gradually increases and does not exceed the maximum nitrogen charging pressure specified by the system.

Pressure compliance:

Once the accumulator reaches the predetermined nitrogen charging pressure, turn off the pressure source of the nitrogen charging tool.


After the accumulator is filled with nitrogen, carefully disconnect the accumulator nitrogen charging tool from the accumulator.


Use pressure measuring equipment to check if the gas pressure of the accumulator reaches the expected value. This ensures that the accumulator can operate normally in the system.

Please note that this is only a general usage step. The actual operation may vary depending on the type of accumulator, brand and design of nitrogen charging tools, etc. Before using the accumulator nitrogen charging tool, please read the relevant operating manual and instructions to ensure correct and safe nitrogen charging operation. If you are unsure how to use the accumulator nitrogen charging tool, it is recommended to seek guidance from a professional hydraulic engineer.
