A hydraulic system works better when its pressure is steady rather than swinging. A bladder accumulator stores pressure and smooths it out.
Inside is a gas filled bladder that gives and takes as the pressure changes, evening out the swings and holding pressure ready.
This guide explains what a bladder accumulator does, where it fits, and how to keep it reliable.
What a Bladder Accumulator Does
Inside the accumulator is a bladder filled with gas, sitting against the hydraulic fluid.
When pressure rises the gas is squeezed and stores energy, and when pressure falls the gas pushes back, so the swings are evened out.
So the accumulator smooths the hydraulic pressure and holds some ready for when it is needed.
Where It Fits in the Plant
Hydraulic systems that drive mill parts, grabs, and other equipment suit an accumulator to steady their pressure.
Where pressure swings would jolt the equipment, the accumulator smooths them out.
By holding steady pressure, it helps the hydraulics work smoothly.
Signs the Accumulator Needs Attention
An accumulator in trouble shows up in the pressure.
- Pressure swinging more than it should
- The gas charge in the bladder falling
- The bladder failing inside
- Leaks at the accumulator
- The hydraulics jolting where they were smooth
What Makes a Good Bladder Accumulator?
An accumulator is judged by holding its charge and smoothing pressure.
Holding the Gas Charge
The bladder must hold its gas charge to store pressure. Holding the charge is what lets it smooth the pressure.
Smoothing the Swings
The accumulator must even out the pressure swings. Smoothing the swings is the reason for it.
Keeping the Accumulator Running
Routine attention keeps an accumulator steadying your hydraulics.
- Watch that the pressure stays smooth
- Check the gas charge in the bladder
- Watch for leaks at the accumulator
- Replace a failed bladder promptly
Common Questions About Bladder Accumulators
It stores hydraulic pressure in a gas filled bladder, smoothing out pressure swings and holding some pressure ready for the hydraulic system.
The gas in the bladder is squeezed when pressure rises and pushes back when pressure falls, which evens out the swings in the hydraulic system.
The bladder must hold its gas charge to store pressure. If the charge falls, the accumulator can no longer smooth the pressure well.
Watching that the pressure stays smooth, checking the gas charge, watching for leaks, and replacing a failed bladder keep it steadying the hydraulics.
Steady the Hydraulic Pressure
A bladder accumulator stores and smooths hydraulic pressure with a gas filled bladder, so the hydraulics work smoothly. Holding the charge and smoothing the swings are what make it work.
If your hydraulic pressure jolts, an accumulator can steady it. Explore our equipment for the right one.
