Accumulators stores the system fluid under pressure and delivers it back to the system under pressure whenever needed.
This storage holding period could range from a few seconds to several days, which means that the accumulators must be pre-charged with required correct gas pressure beforehand to ensure the system is held under control.
If the accumulator does not have the correct pre-charge pressure, it will not be able to provide the required backup fluid flow which could undermine operating system performance or make it out of control, leading to a catastrophic failure. Hence, it’s a critical maintenance issue that all accumulators be it of any type, has always been kept and maintained with the correct pre-charge pressure at all times.
To facilitate this pre-charging and monitoring of gas pressure in an accumulator, Accumulators Charging Kits are used
We offer Universal charging and testing kit, which is used to charge bladder, piston and diaphragm accumulators with nitrogen, or to test and alter the pre-charge pressure.
To suit different gas-side adapters to the accumulator, requisite adaptor can be provided.
The kit is primarily, comprised of
- Charging Block Carbon steel body with spindle, check valve and release valve
- Pressure gauge with display ranges upto 400 bar.
- Charging hose
- Case with Inlay or loose parts.
- Adaptor for bladder accumulator
- Adaptor for commercial gas bottle.
- Available Pressure Gauge range : 10, 25, 50, 100, 250, 400 bar.
- Available Hose length : 2.5 mtr (standard length), 4 mtr, 6 mtr, 10 mtr, 15 mtr & 30 mtr.
- Available Adaptor : To suit different make Accumulator and Different user country Nitrogen Gas bottles.
The charging block of the Kit is screwed on the gas valve of the accumulator and connected with the attached hose to a commercial nitrogen bottle. A Pressure reducing valve with a gas relief feature should be used of if the operating pressure of the accumulator is lower than that of nitrogen vessel.
If the pre-charge pressure is only required to be checked or reduced, then it can be done by using the charging block alone.
