Hydraulic Accumulator Division Rockford, Illinois USA Catalog HY10-1630/US Hydraulic Accumulators Bladder Accumulators Maintenance Instructions Pre-Charging Use only an inert gas such as nitrogenfor precharging piston accumulators. Do not use oxygen or shop air. If water pumped nitrogen is not available, oil-pumped nitrogen may be used.

Since hydraulic accumulators are pressure vessels, the installation, commissioning, disassembly, and maintenance should be performed by professionally trained and

Hydraulic Accumulator Division Rockford, Illinois USA Catalog HY10-1630/US Hydraulic Accumulators Maintenance Instructions Water Service Option (W) Piston accumulators are available for use with water as the fluid media. Modifications include electroless nickel plating all surfaces and metal parts. Consult factory for details.

HYDRAULIC ACCUMULATORS - ROBUST AND VERSATILEWherever hydraulic tasks need to be Procedures for Bladder Maintenance Gas-charged accumulators are 

ROBUST AND VERSATILE: Wherever hydraulic tasks need to be performed, HYDAC hydraulic accumulators can help. They are versatile, make your machine more convenient to use, secure

Hydraulic accumulators are pressure vessels and must be treated accordingly. Only trained and qualified individuals should perform installation and maintenance procedures on any accumulator. Always wear personal protective equipment (safety glasses and chemical resistant protective gloves, if necessary)

G) Crack open nitrogen bottle valve and slowlyfill accumulator. Shut off when gauge indicates desired pre-charge. (H) Let the pre-charge set for 10 to 15 minutes. This will allow the gas temperature to stabilize. If the desired pre-charge is exceeded, close nitrogen bottle valve, then slowly open bleed valve (Figure 1).

Open al l flow controls and isolate any accumulators. • Set the relief valve 200 PSI above the maximum operating pressure •Colse the Hand Valve. • Adjust the relief to 1200 PSI. (For this example) • Turn the system off, open the hand valve and remove the gauge. Setting the Relief Valve in a Fixed Displacement Pump Circuit

Hydraulic accumulators should be carefully inspected visually at least once per year, more often in environments unfriendly to steel. Ensure there are no rust spots or cracks in the

The following safety instructions must always be followed when working with hydraulic accumulators: Only use an inert gas like nitrogen for a pre-charging. Nitrogen that is 99.99 percent by volume is strongly recommended. Do not use oxygen or shop air, as this may lead to a fire or explosion. Modifying a bladder accumulator (i.e. welding,

Maintain constant pressure on a hydraulic system such as a press line where multiple presses are opened and closed at different times. Thermal Expansion:.

Maintenance & Procedures - Accumulators, Inc.

Pre-charge Maintenance Interval It is recommended to check pre-charge pressure after 1 week of commissioning and then after 3 months into operation. Thereafter, depending on the measured loss of pressure and performance, this can be scheduled from 3-6 months or even longer.

Bladder Accumulators - CE Marking Water & Chemical Service Option (W) Bladder accumulators are available with a water and chemical resistance options. The (W) designation includes an internally

Additionally, leaking and maintenance costs can both be reduced as accumulators mitigate system shock and thus promote longer service lives of parts. Coupled with improved performance, lower noise levels, reduced energy costs, and heightened flexibility in design, accumulators are very beneficial for many applications.

Hydraulic accumulators are pressure vessels and must be treated accordingly. Only trained and qualified individuals should perform installation and maintenance procedures on

1.Steel pressure oil container 2.Rubber bladder separating the fluid and gas 3.Oil valve that prevents the bladder from being pressed out of the accumulator when the hydraulic pressure is lower than the charging pressure of the bladder. 4.When charging the bladder to the desired pressure required a gas valve 5.Valve cap

While accumulators present a number of advantages in hydraulic system operation and can provide many years of trouble-free service, they are a maintenance item. For example, the correct gas pre-charge pressure must be maintained for proper functioning and optimum service life.
