How can hydraulic shock be absorbed in a system circuit?

The accumulator is a crucial component in hydraulic systems used to absorb hydraulic shock. When there is a sudden change in pressure, such as when a valve closes quickly or when hydraulic cylinders change direction, the resulting shock can create a hydraulic hammer effect, which can cause damage to the system.

An accumulator serves as a buffer, storing excess fluid in a bladder or piston mechanism under pressure. When a spike in pressure occurs, the accumulator can absorb this sudden increase in hydraulic fluid volume, thus dampening the shock transmitted throughout the system. This not only helps protect sensitive components but also ensures smoother operation by maintaining more consistent pressure levels.

By utilizing an accumulator in the circuit, the hydraulic system can operate more efficiently and with reduced risk of damage from rapid pressure fluctuations, contributing to the longevity and reliability of the equipment.
