Hydraulic System Life Span – Minimum and Maximum

While working with hydraulic systems, it is important to understand its anatomy in and out. Careless usage of a hydraulic machine can shorten down its possible life drastically.

Reasons for a shorter life span

The most shared reason for the decline of a hydraulic system is hydraulic fluid contamination. Inadequate efforts at removing contaminants from fluid or avoiding the substitute of hydraulic fluid until a harsh fluid breakdown occurs, generally reasons the poor performance of system over a period of time. Most often the contaminants go into the system in form of dust with metal or rubber besides, entrapped water and air too contaminate the fluid. In order to continue clean and clear hydraulic fluid, it is wise to inspect the fluid samples regularly.

Fluid contamination can also be called “additive decline” as additives are the meaningful source which provide the oil with certain specific characteristics. Since these additives are more unprotected to chemical and physical changes, their decline can consequence into fluid breakdown. Fluid decline often occurs due to high temperatures hence, it is advised to keep the fluid operating temperatures well below 60 degree Celsius (140 degree Fahrenheit). Now-a-days most of the hydraulic strength units are laced with heat changers, temperature controls and over-temperature.

Solutions to elongate the life span

The life of a hydraulic system can be maximized to the fullest by keeping a regular check over the clarity of hydraulic fluid. The two major things which needs to be looked after are fluid contaminants and the chemical composition of fluid.

The best way to inspect fluid is sampling the fluid first and then analyze it. It gives a fair amount of idea as to whether the fluids or filters needs to be replaced or not. Such examination can also help in calculating the exact viscosity of the fluid in addition as detecting the contaminants in it like water or other foreign particles. Besides, it can also prove helpful in calculating the chemical composition of the fluid to know whether it can nevertheless be used further or not.

A thoughtful evaluation of contaminants and its source within the hydraulic system is extremely important to avoid them in future in addition as elongate the working life of a hydraulic system to the utmost.
