Hydraulic cylinder hydraulic valve hydraulic system

What are the causes of noise in the hydraulic system? There are many sources of vibration and noise in the hydraulic system, including mechanical system, hydraulic pump, hydraulic valve and pipeline. Vibration and noise of the mechanical system vibration and noise of the mechanical system are mainly caused by the mechanical transmission system driving the hydraulic pump, mainly in the following aspects:

1) Unbalance of rotating bodies in practical applications, most of the motors drive the hydraulic pump through the coupling. It is very difficult to achieve complete dynamic balance of these rotating bodies. If the unbalance force is too large, it will produce large bending vibration of the rotating shaft during rotation and generate noise.

2) Improper installation of hydraulic system often causes vibration and noise due to problems in installation. If the system pipeline supports poorly and the foundation is defective, or the hydraulic pump and the motor shaft are not concentric, and the coupling is loose, these will cause large vibration and noise.

2. Hydraulic pump (hydraulic motor) is usually the most important hydraulic component that generates vibration and noise in the whole hydraulic system The vibration and noise of the hydraulic pump are caused by the mechanical vibration on the one hand and the accumulation and change of the liquid pressure flow on the other hand.
