Noise reduction in hydraulic systems often involves isolating the pump and prime-mover assembly using flexible mounts (isolators). In these cases, the use of hose is necessary to maintain the isolation between the pump and prime-mover and the rest of the system.
The flip-side to this though is, although long lengths of hose can reduce structure borne noise, hose is actually … Read more
What do lifting chains, bladder-type accumulators and hydraulic hoses all have in common? They typically have only one mode of failure – and that’s catastrophic. One minute they’re working as they should and the next thing you know, they’ve gone to hell.
Oh sure, hoses can leak from around their ferrules and show obvious signs of abrasion, both of which … Read more
Clause 5.4.6.5.1 a) of ISO 4413:2010 “Hydraulic fluid power – General rules and safety requirements for systems and their components” states: “hose assemblies shall be constructed from hoses that have not been previously used in operation as part of another hose assembly…”
This means squeezing a new end onto a hydraulic hose that has previously been in service … Read more
