ACCUMULATORS Hydraulic accumulators are pressurized vessels and only qualified technicians should perform maintenance. For additional information refer to HYDAC Operating and Installation Instructions and HYDAC Maintenance Instructions. Read all instructions thoroughly before before beginning any type of service or repair. Tools Required 1. Gas Valve Core Tool. 2. Torque Wrenches. 3. Wrench(es).
ACCUMULATORS Checking Gas Precharge Pressure Charging Connect the appropriate charging and gauging unit to the accumulator following the instructions under “Preparation” (see page 2). Note: Temperature affects the gas precharge pressure, please refer to “Temperature Effect” (see page 2). Never use oxygen or air - this could cause an explosion! Use dry nitrogen or other recommended gases. FPS Unit Turn T-handle “A” clockwise a maximum of 3 full turns from the full counterclockwise position.
ACCUMULATORS When charging an accumulator that has an existing gas precharge, allow 5 to 10 minutes for the gas temperature and thus pressure to stabilize. FPS Unit Turn T-handle clockwise until the gauge needle begins to deflect, then turn it another full turn. Proceed to “Filling”. FPK Unit Turn T-handle counter clockwise until the gauge needle begins to deflect, then turn it another full turn. Proceed to “Filling”.
