Analisis Kegagalan O-Ring Seal Akumulator Steering System Dump Truck
Abstract: Occurrence of
O-ring seal leakage
accumulator Dump Truck
steering system causes
the movement of components to be unstable and difficult to control. A
series of tests have been conducted to determine the cause of leakage and
mitigation efforts include: Visual testing,
Dimensional testing, Testing Physical and mechanical properties of
materials. It was found that the O-ring
seal leakage caused by
overheating due to excess hours of
operation that causes changes in the
physical properties that impact on changes of mechanical properties by increasing
tensile strength (79.92%)
and reduced elongation
(14.8%). Reduced elongation ability
would greatly influence the ability of O-ring seals as seals and to result
leakage. It is necessary to note the working temperature of the fluid with
respect to hours of operation of the unit as recommended by the manu facturer.
