What creates noise in hydraulic systems and why is it important to eliminate it?
Noise in hydraulic systems is generated primarily by the mechanical workings of the pump and fluid pulsations exiting the pump as it supplies the flow for the system. It can also be created by any element that causes turbulence of fluid velocity change. Noise is additive, so small amounts of noise from many components can be effectively amplified resulting in a significant noise problem. The transmission of the noise to the operators of the equipment can cause fatigue, nerve damage, and require operators to wear additional hearing protection.
