Full Technical Description

097 343 18H ACCUMULATOR, DIAPHRAGM Located within the drifter's main hydraulic circuit, this accumulator is at the heart of the percussion mechanism. Its primary role is to absorb hydraulic energy from the pump during the piston's return stroke and then release that energy in a rapid burst. This cycle creates the high-frequency impact force required to fracture rock effectively.

A correctly functioning accumulator is essential for maintaining the drifter's rated performance. If the internal nitrogen pre-charge is too low, the impact energy will drop significantly, slowing down your penetration rate and increasing stress on other hydraulic components. It also dampens pressure spikes, protecting hoses and seals from premature failure.

A common sign of a failing accumulator is a noticeable loss of drilling power or a 'soft' hitting sound from the drifter. Before attempting any service, always ensure the hydraulic system is fully depressurized. Checking the nitrogen pre-charge regularly is the best way to ensure a long service life and consistent drilling results.
