FAQs about Working principle of nitrogen accumulator check valve

How does a nitrogen accumulator work?

An accumulator charges when system pressure increases, causing fluid to flow into the accumulator and compressing the nitrogen gas. It is discharged when system pressure decreases, letting nitrogen in the accumulator expand and send the fluid out of the accumulator.

How low should nitrogen charge be in a accumulator?

The nitrogen charge in this case is usually kept 5% below the working pressure to ensure the accumulator is out of the circuit except during pressure spikes.

How does a check valve work?

The valve forces pump flow to the accumulators when pressure drops approximately 15% below its maximum set pressure. At set pressure, the unloading valve opens and all pump flow bypasses to tank at 25- to 50-psi pressure drop. While the pump is bypassing, a check valve keeps the accumulators from unloading to tank.

To maintain pressure: Another common application for accumulators is to maintain pressure in a circuit while the pump is unloaded. This is especially useful when using fixed-volume pumps on long holding cycles.

How do accumulator pumps work?

Now, stored energy in the accumulator is ported to tank through the orifice. This circuit is very reliable because it depends on system or pump pressure to close and/or open valves. A fixed-volume pump must be ported to tank at very low pressure when its flow is not doing work.
