How Accumulators Work | Clean Automotive Technology

The accumulators use nitrogen to keep the hydraulic fluid pressurized. When the fluid is pumped into an accumulator the nitrogen (N2) inside the accumulator is compressed. When all the hydraulic fluid is in an accumulator designed for high pressure side of an HHV, the pressure of the nitrogen reaches 5000 pounds per square inch (psi).

The Role Of Nitrogen In A Hydraulic Accumulator

Additionally, nitrogen''s inert and non-reactive nature minimizes the risk of combustion or reaction with hydraulic fluid, further enhancing overall safety. Nitrogen Compounds and Nitrogen Cycle: While nitrogen gas (N2) is

What is an accumulator?

Pneumatic systems take advantage of the pressure differential between compressed air and the atmosphere. Air compressors "suck" in ambient air, and then compress it to 1/7th to 1/11th of its original volume to achieve

6 FAQs about [Filling the nitrogen accumulator with compressed air]

How to fill a nitrogen accumulator?

Here are the steps to fill the accumulator: Before you start the filling process, make sure that your nitrogen refill station is in good working condition. Check the pressure gauge and ensure that the nitrogen supply valve is open. If the nitrogen supply in your refill station is low, refill it to the recommended pressure level.

How do you fill a nitrogen accumulator with a pressure gauge?

Attach the pressure gauge to a different source of nitrogen. Slowly open the valve to allow the pressure gauge to fill with nitrogen. Observe the pressure reading on the gauge and make sure it matches the desired pressure for your accumulator. If the pressure is too low, repeat the filling process until the desired pressure is obtained.

How do you charge a nitrogen accumulator?

Gently screw in the T bar handle (CW) to open the charging fill valve to allow nitrogen gas to enter the accumulator. At this time, the actual precharge pressure will be seen on the gauge when gas from the accumulator fills the line. Slowly open the fill valve from the top of the nitrogen tank to start charging the accumulator.

How do hydro-pneumatic accumulators work?

All hydro-pneumatic accumulators function due to the differential pressure between the compressed nitrogen gas and the stored hydraulic fluid. It is extremely important to provide the proper amount of gas pre-charge, dependent on the accumulator application, and check the gas pre-charge level regularly.

How do you maintain a nitrogen accumulator?

Regularly monitoring and maintaining the correct pressure will also help prolong the life of the battery and prevent any potential damage. Once you have properly set up your nitrogen refill station, it’s time to fill the accumulator with nitrogen gas.

How does filling a nitrogen accumulator affect the efficiency of the process?

The filling technique used during nitrogen charging can greatly affect the effectiveness of the process. Inadequate filling techniques, such as using improper equipment or not filling the accumulator with nitrogen slowly and steadily, can lead to incomplete charging and the presence of air pockets within the accumulator.
