5 Reasons Hydraulic Machines Fail
5 Reasons Hydraulic Machines Fail
Hydraulic systems play a very critical role in everyday life, as they are used to accomplish a wide range of complex tasks.
They have made work simpler even if some people don’t realise it.
However, despite the important role these systems play, hydraulic machine failure is still bound to occur.
There can be different reasons for system failure but there are things that can be done to prevent these failures or repair them.
Below are 5 reasons hydraulic machines fail and possibly how they can be avoided or handled.
- Hose tears, wears, and abrasion
If not properly installed, the hose assemblies can be problematic and can attract huge costs.
Similarly, if not repaired in time to minimise contact with other machine components that could be affected as part of the system.
When the hydraulic hose rubs against mechanical components, it is likely to suffer wear and tear and abrasion.
Excess abrasion can cause premature hydraulic hose failure and failure of the hose can cause the entire hydraulic system to fail.
This can be prevented right from the installation phase by ensuring proper installation procedures are adhered to so that hose assemblies and mechanical components are fitted properly and do not rub against each other to cause wear and tear or abrasion, which can eventually lead to machine failure.
- Weathering and heat ageing
Overheating of a hose can cause thermal expansion, which can, in turn, cause elastomers and plastics of the hose material that comprise the internal hose tube to age prematurely.
This can result in decreased elongation of the material’s molecular structure, thereby potentially increasing the brittleness and eventually leading to machine failure. So, to prevent overheating, the level of fluid should be checked to ensure it is optimum.
The fluid level should not be too low to cause overheating and shouldn’t be any obstructions in the airflow near the reservoir. When heat is generated, it needs to escape and the cooling system has to work properly to prevent overheating.

- Temperature problems
Any hydraulic system that is too hot or too cold will not run properly and can lead to various problems over time.
Heat causes expansion and thinning of fluids, thereby preventing adequate lubrication and leading to leakage.
On the other hand, low temperatures tend to increase the viscosity of hydraulic oil, thereby preventing the oil from reaching the pump easily, overloading the system and possibly damaging it.
- Fluid contamination
Fluid contamination causes degrading of the fluid, affecting the ability of the valve to regulate pressure.
Failure to control the pressure can lead to overheating and ultimate system failure.
- Human error
Human error can come in many forms; from faulty system installations to parts incompatibility issues.
Inexperienced installers can mismatch parts and components, resulting in system failure.
Therefore, hydraulic engineers need to be on the lookout for reasons that can cause hydraulic machines to fail and correct those problems as soon as possible to prevent potentially costly damage.
