The use and maintenance of energy storage devices mainly include installation, maintenance, fault diagnosis, troubleshooting, and repair. The installation of the accumulator includes pre installation inspection, installation, nitrogen charging, etc.

Proper installation, fixation, and inflation are important conditions for the normal operation and proper functioning of the accumulator. The measurement of parameters and the correct use of various tools and instruments cannot be ignored.

The internal cavity of the accumulator is divided into two parts by the skin bag: the bag is filled with nitrogen gas, and the bag is filled with liquidPressure oilWhen the hydraulic pump injects hydraulic pressure into the accumulator, the bladder is compressed and deformed, and the gas volume decreases with increasing pressure. The hydraulic oil gradually accumulates pressure. If the hydraulic system requires an increase in hydraulic oil for operation, the accumulator will discharge the hydraulic oil to compensate for the system's energy.

1. The accumulator should be installed vertically downwards on the oil day. Seal the gas in the upper part of the shell to prevent it from entering the pipeline.

2. Welding, riveting, or mechanical processing methods are not allowed to fix the accumulator.

3. It is strictly prohibited to charge the accumulator with oxygen or air. Must be filled with nitrogen or other gasnoble gas.

4. When storing energy, the inflation pressure should be lower than 90% of the system's low working pressure (usually 60% to 80%)

5. After installing the accumulator, check if there is any air or oil leakage at the interface.

6. After the accumulator is set, it should be checked for air pressure and technical inspection according to the prescribed period. Inspection and maintenance

1. Check for air leakage: After setting the accumulator, start checking the capsule pressure once a month, and then check it every six months.

2. Inspection method: Install a shut-off valve on the oil circuit connecting the inlet of the accumulator and the oil tank, and install a pressure gauge before the shut-off valve. Slowly open the shut-off valve to allow the pressure oil to flow back to the oil tank, while paying attention to the pressure gauge and its pointerThe inflation pressure is the value that gradually decreases and rapidly drops to zero after reaching a certain pressure value, and the speed at which the pointer moves changes. In addition, inflation tools can be used to directly check the inflation pressure, but a little gas will be released every time it is checked.

3. When the skin bag is damaged, the pressure oil must be released before removing the accumulator, and then all components can be removed
