Abstract:
This experiment to identify the contamination control with hydraulic oil used a 250 ton
Hitachi hydraulic excavator, which is commonly used in coal mining operations. The aim is to
analyze the effectiveness of an off-board filtering system to reduce the particles
contaminant PC06 and PC14 in hydraulic oil. The experiment shows the additional flushing
activity to clean the hydraulic oil using an off-board. The tool could reduce the particle
contaminants in hydraulic oil compared to the normal operating condition. The hydraulic oil
is generally filtered by a hydraulic system filter compartment attached to the system itself
(on-board at the machine). The signal to noise ratio (SNR) value of the filter factor reaches
an optimum when using the off-board with a 4 × 10 µm filter compared to the standard
filtering by machine operation. At the time factor, it comes optimal at level 1 (Time 1000) so
that the combination of filter and time can optimize the critical parameters PC06, PC14, and
V100 in hydraulic oil. © 2022, The Author(s), under exclusive license to Springer Nature
