What are the causes of noise in the Hydraulic System? Technical point out: There are many sources of vibration and noise in hydraulic system, such as mechanical system, hydraulic pump, Hydraulic valve and pipeline. Vibration and noise of mechanical system Vibration and noise of mechanical system are mainly caused by mechanical drive system driving hydraulic pump, mainly in the following aspects:
1) In practical application, most of the motors drive Hydraulic pumps through coupling. It is very difficult to achieve complete dynamic balance of these rotating bodies. If the balance force is not too large, large bending vibration of rotating shaft will occur and noise will be generated during the rotation.
2) Improper installation of hydraulic system often causes vibration and noise due to problems in installation. If the piping support of the system is not good and the foundation is defective or the hydraulic pump is not concentric with the motor shaft, and the coupling is loose, these will cause greater vibration and noise.
2. Hydraulic pumps (Hydraulic Motors) are usually the most important hydraulic components which generate vibration and noise in the whole hydraulic system. Vibration and noise of hydraulic pump are caused by mechanical vibration on the one hand and accumulation change of liquid pressure and flow on the other.
These are related introductions in this regard, hope to be helpful to your daily work.
