Agricultural Machinery Hydraulic Pumps Suppliers hydraulic pumps are composed of many parts. Due to the manufacturing errors of the parts, improper assembly may cause vibration and noise of the hydraulic system. There are two types of hydraulic pumps:

1. Mechanical sound

Most hydraulic valves are composed of valve core, valve body, control parts, fasteners, seals, etc. They move the valve core through external force, and the valve core moves to the corresponding position to change the liquid flow to meet the Work begging. During this process, the mechanical contact of the moving parts in the valve produces noise.

The hidden danger of improper assembly of hydraulic press parts

2. Fluid sound

Hydraulic Gear Pumps Manufacturers Due to the hydraulic valve at the end of throttling, reversing, overflow, the flow rate, direction and back pressure of the liquid flow in the valve body undergo various changes, resulting in the vibration of the valve parts and the wall of the pipeline, resulting in noise. According to the cause of the pressure vibration, it can be divided into cavitation sound, motion sound, hydraulic impact sound and shock sound. The vibration and noise of the pipeline are mainly caused by the interaction of the vibration of hydraulic components such as pumps and valves on the pipeline. Studies have shown that when the length of the pipeline is exactly equal to an integer multiple of half the wavelength of the vibration pressure, severe high-frequency noise will occur in the pipeline.
