Crushing Hammer Accumulator Charge Pressure

What is the Best Charge Pressure for My Accumulator?

The piston can often be heard bottoming, warning of impending problems. In a bladder accumulator the bladder can be driven into the poppet assembly when discharging. This could cause a fatigue failure of the poppet spring assembly, or even a pinched bladder. Excessive pre-charge pressure is the most common cause of bladder failure.

ensure the bladder. doesn''t quite touch. the poppet. Typically, the accumulator precharge is set to between 60% and 80% of the minimum system pressure. That way the bladder doesn''t expand enough to close the poppet during normal operation. Accumulators are precharged with dry, inert, nitrogen gas rather than simply using compressed air.
