Hydraulic systems are a common component of heavy machinery. From vehicles to industrial machines, it is installed in almost all kinds of products. When it is out of order, you can not even estimate the loss. So, it is critical to regularly conduct maintenance checks. If there is a need for hydraulic hose repair, contact professionals, or if it needs to be replaced, try yourself, if possible. Why is hydraulic hose failure exemplified? It is because it is the core part of the hydraulic system and its failure will result in huge damage to the system. In this case, early fault detection and intervention followed by later prevention are helpful.
Hydraulic Hose: Basic introduction
Do you know the function of a hydraulic hose? It carries the function of fluid circulation in the hydraulic system. The fluid circulates fast at high pressure. Without a hydraulic hose, you cannot imagine a functional hydraulic system. These hoses also protect fluids from external contamination. If the failure occurs, it indicates that it cannot hold the fluid anymore, and also there is no protection from the external pollutants making their way to the internal fluid. Hydraulic hose failure affects system performance and also results in critical damage that requires costly repairs.
There are 3 sub-components of a hydraulic hose. These are a tube, reinforcement, and a cover. The core or internal most part is a tube that is in direct contact with the circulating fluid. The tube is strengthened by the reinforcement to bear pressure induced by circulating fluid. The external part is the cover – protecting the other 2 components. For the sake of hose protection, there can be extra protective covers. Hose assembly, other than a hose, links various components of the hydraulic system via ports.
Failure of a hydraulic hose
The minimum lifetime of a hydraulic hose is 1 or 2 years while it extends up to 10 years for quality products. Hence, if your hydraulic hose fails to function properly in the first 2 years, then consider external causes resulting in reduced hydraulic hose life.
High temperatures are one of the causes why hydraulic hoses go out of order. Primarily, if the hose is in contact with any of the components with negatively high temp, the hydraulic hose failure happens. Surface wear, scrapes, and cuts can occur when a hydraulic hose comes into contact with vibratory components, reducing the hose’s useful life.
Another issue commonly reported is related to chemical compatibility. It is a very serious cause and can risk the integrity of the hydraulic hose. So, it is suggested that you do compatibility checks for the tube material. Make sure it is safe with the medium (fluid) that will be circulating through it. Incompatibility may result in a weak and failed hydraulic hose.
The article provided a brief overview of hydraulic hose failure, causes, and solutions – replace or repair. Moreover, irrespective of the pressure gradient, operating a hose that isn’t suitable for the working pressure of the system might result in hazardous surge circumstances. Causes vary from the kind of hose material or kind of reinforcement used. So, you should evaluate the cause early and then opt between repair or replacement.
