Statistical Analysis of the Pollution of a Hydraulic Oil Based on the Evolution of the Filter Clogging on the Pressure Pipe
Journal Title: HIDRAULICA - Year 2018, Vol 0, Issue 1
Abstract
We present in this paper the results of an experimental study conducted on the analysis of the influence of clogging of a hydraulic filter, installed on the discharge pipe of a variable displacement pump, the operating pressure is 210 bar. The pump is used to supply hydraulic power to a finisher in the rolling mill at the iron and steel complex in Algeria. In this context, we tested the filter retention efficiency, whose mesh size of the filter element is 15 μm. The influence of the service time and consequently the number of pollutant particles retained per filter on the singular pressure loss ΔP of the filter were characterized. A statistical analysis conducted on the representative sample of ΔP values, followed by adjustment tests has been made. The statistical analysis carried out clearly shows that the evolution of the local pressure losses at the level of the filter follows a Beta law. Knowing such a distribution law of a variable is an advantage that will help to establish a predictive maintenance program, with the aim of acting in time, and this to remedy the failures, whose oil pollution is considered the main cause.

Phenomenon of Transiency in Water Supply Systems
Transient is a flow condition in which velocity and pressure change rapidly with time. A transient normally occurs when a flow control component changes status and this change flows through the system as a pressure wave...
