Oil Contamination

AXB Technology Co., Ltd. has concluded a general analysis of oil contamination.

Analysis Item	Criteria	Causes and Effects when exceeds the criteria
Adhesiveness	Within ±10 %40℃ cst	Adhesiveness rarely decreases solely because of hydraulic oil. Entry of different kind of oil may reduce the adhesiveness with contributes to rising oil temperature, wear and stretch of bearings and gears and malfunction of hydraulic oil.
Oxidizing Level	Less than 0.3 (mg KOH/g)	Use of a lubricating oil in a long period of time of under high temperature of a lubricating (higher than 60℃) will oxidize it. Oxidizing level rises as Oxidization proceeds. Sludge will be produced during the process. Leading to unsatisfactory operation of the breaker, erosion of Metals or obsolescence of seal materials.
Moisture	Less than 0.1(%)	Moisture causes rust, wear and stretch. Moisture of 1.3% gathers a considerable amount of rust. And considerable a mount of rust moisture of 0.5% or more will cause damage to the machine.
