Accumulator Accessories

Accumulator accessories refer to various auxiliary components and tools used for the installation, charging, adjustment, monitoring, maintenance, and repair of accumulators in hydraulic systems. These accessories are not the main structure of the accumulator (such as the bladder or piston), but rather peripheral components designed around its "gas side" and "oil side."

The following are the main categories and functions of accumulator accessories:

1. Gas Side Accessories (for charging and safety control)

This is the most critical accessory category, mainly involving equipment for charging the accumulator with nitrogen (or other inert gases) and controlling gas pressure relief.

Charging tools and devices: including gas charging valves, nitrogen booster packs, and charging tool kits.

Safety valves and rupture discs: used to prevent overpressure; common examples include safety valves and rupture discs.

Exhaust valves: used to remove moisture or impurities from inside the accumulator, ensuring pure charging.

Instruments: including dual-sided pressure gauges (for displaying oil and gas side pressures), gas pressure gauges, gas pressure regulating valves, etc.

2. Hydraulic Side Fittings (for connection and valve control)

Connecting Piping: Includes gas-side piping, hydraulic-side piping, and various flanges and fittings (such as high-pressure ball valves and three-way valves).

Hydraulic Side Valves: Includes hydraulic-side safety valves and hydraulic-side shut-off valves, controlling the inflow and outflow of hydraulic oil.

3. Installation and Maintenance Accessories

Fixed Brackets and Accessories: Includes accumulator supports, fastening clamps, lifting lugs, etc., for installation and handling.

Maintenance Tools: Includes disassembly and assembly tools, leak detection instruments, etc., for routine maintenance of the accumulator.

Cooling Equipment: For high-power accumulators, a cooler may also be provided.

4. Special Accessories

Seals: Such as sealing rings, oil seals, O-rings, etc., used to maintain the separation of gas and hydraulic fluid.

Special Accessories: Such as nitrogen filling trucks (for rapid on-site filling).
