That is why we cover topics like this, to help improve the operation of your hydraulic machinery.

What generates noise in hydraulic equipment?

So, starting with the obvious, what is noise generation? This is generated by the mechanical innards of the pump and the fluid moving through the pump as it flows through the system. Another cause for it is when components cause fluid change or turbulence. The issue is that noise is additive so even small amounts can lead to larger issues.

Why is noise generation undesirable in hydraulic equipment?

You want your hydraulic machinery to operate efficiently and effectively, right? Well, noise generation can cause additional load on your hydraulic parts, which can cause premature failure for those components and your system as a whole. In particular, noise generation wreaks the most havoc in steel tube assemblies. This is because they are extremely susceptible to vibration failure. Noise generation also impacts your workers and can make working conditions unsafe or undesirable.

How do you reduce noise generation in hydraulic equipment?

Even small noise generation in your hydraulic system can be detrimental so you should do whatever necessary to reduce it. To completely eliminate noise generation, you can install attenuators that can be tuned to cancel out the frequency of the system. Unfortunately, these are expensive and typically pretty bulky. The alternative to this, is using hydraulic hoses that have various volumetric expansion rates. These help, but the hoses can be more costly. Alternatively, you can also use thermoplastic reinforced hoses to eliminate noise in your hydraulic system. These type of hoses are constructed using different polymer inner cores with varying chemical compatibility and polymer jackets. If you are looking for a cost effective way to reduce noise generation in your hydraulic system, this might be the way to go.
