Before we know about charging a hydraulic accumulator, let’s learn the basics of what it is and it’s importance. A hydraulic accumulator holds fluid under pressure as per the definition of an accumulator. It aids in maintaining a stable pressure, lessens wear on the system and offers extra force when required. It is an essential procedure to charge a hydraulic accumulator to ensure its function and service life.
“Charging” a hydraulic accumulator involves filling it with a pressurized fluid as a way to store energy for subsequent use. The details of the steps can vary depending on the type of accumulator, but the main ideas are the same. The accumultor is comprised of two sections: a gas section and a liquid section divided by a diaphragm or piston. One side is filled with gas, such as nitrogen, by the gas, and the other side is filled with hydraulic fluid.
Locate the Charging Valve: The charging valve on the accumulator needs to be located, and then you will plug a pressure gauge with a charging hose.
Start Gas Valve: Gradually open the gas valve to allow gas in the accumulator. Check on the pressure gauge to ensure that the gas is at the correct pressure.
Shut the Gas Valve: Once the gas side is pressurized, shut off the gas valve and remove the hose. Be sure to release any trapped air or gas from the hose before removing it.
It is of great significance to charge a hydraulic accumulator properly for the safety and performance of the system. If you undercharge it or overcharge it, you can have problems or leaks or damage. If you take the right steps and apply just the right pressure, you can assist the accumulator in performing well and having a longer life.
