Solution To Hydraulic System Noise Of Hydraulic Cylinder
Cross-section design: When designing the hydraulic system's pipe layout, it is advisable to avoid sudden changes in the cross-section, such as abrupt increases or decreases in pipe diameter. These sudden changes can cause turbulence and swirl in the flow, leading to pressure drops and inefficiencies. If elbows are necessary, it is recommended to use ones with a radius of curvature at least five times the diameter of the pipe to minimize flow disturbances.
Use of accumulators and mufflers: To absorb pressure fluctuations and reduce vibration in the hydraulic system, theuse of accumulators and mufflers is recommended. Accumulators can store hydraulic energy and release it when needed, reducing pressure fluctuations and minimizing system vibration. Mufflers, or dampeners, can be installed near areas where vibration occurs to absorb and dissipate excess energy, reducing system vibration and noise.
Avoid resonance: Resonance can occur in hydraulic systems when the natural vibration frequencies of system components coincide with the excitation frequencies from sources such as pumps or valves. This can lead to excessive vibration and noise. To prevent resonance, the length of the pipeline can be adjusted to change its natural vibration frequency, and the installation position of certain valves can be modified. By avoiding resonance, system vibration and noise can be significantly reduced.
Vibration isolation: To minimize vibration and noise from the main vibration sources in the hydraulic system, such as pumps or motors, measures can be taken to isolate them from the system's bottom plate or oil tank. This can be achieved by using rubber pads or springs to physically separate the vibration source from the structure or by mounting the vibration source on a separate base to isolate the entire system. These methods help reduce the transmission of vibration and noise to the surrounding components and environment.
It is important to consult relevant standards and guidelines and work with experienced engineers to ensure an optimal design for the specific hydraulic system requirements.
