Accumulator pre charge pressure AccDumFSet is pumping up a balloon, seal it with some pressure. The same way the air helps the balloon maintain its shape and ready to be inflated very fast, the pre charge pressure in an accumulator helps it work well and ready to be used when needed.
So now that you know what accumulator pre charge pressure is, let’s talk about why having it at the correct level is so vital. If the pre charge pressure isn’t properly set, then, the accumulator may not work well.
Think of it as the equivalent of trying to ride a bike that has flat tires: It’s a lot harder to pedal! You're helping the accumulator do its job more smoothly by having the pre charge pressure at the correct level.
Accumulators are small helpers that store energy and discharge it when required, while also being of flexible use. “The pre charge pressure is like giving these helpers a little kick to get them off the couch,” Dr. Lathi said.
If the pre charge pressure becomes too low, the accumulator will not contain sufficient energy. If it’s too high, it can be problematic. You help the accumulator do its best by keeping the pre charge pressure just right.
The temperature can alter the pre charge pressure, since hot or cold weather can increase or decrease the pressure. The gas kind in the accumulator can also be a factor in determining the pre charge pressure. And there can be leaks or trouble in the system that affect it as well.
The other common problem is that the gas charge of the accumulator needs replacing or topping up. You can also help ensure the pre charge pressure is doing its job by inspecting for leaks and ensuring the gas levels are correct.
