The hydraulic filter can filter out all kinds of impurities in the hydraulic system. The main sources are:
The hydraulic filter
1, still remaining after cleaning in the hydraulic system of mechanical impurities, such as scale, casting sand, slag, iron filings, paint, paint skins and cotton scraps, outside into the hydraulic system of impurities, such as the filler and the place such as shield into the dust;
2, the working process of the creation of the impurities, like pieces of a seal is formed by the hydraulic pressure, movement relative wear of the metal powder, the oil for the oxidation of colloid and asphaltene, carbon residue, etc.
After the impurities mixed with the hydraulic oil, as the cycle of the hydraulic oil, everywhere will damage, the serious influence the normal work of the hydraulic system, such as the relatively small gaps between the moving parts in the hydraulic components (microns) and throttle holes and gaps jammed or blocked; Damage relative to the moving parts, the oil film between the cut surface of gap, increase internal leakage, lower efficiency, increase the heat, oil chemical action, and make the oil deterioration. According to production statistics, more than 75% of the fault of hydraulic system are caused by hydraulic oil mixed with impurity, thus maintain the cleanness of the oil, prevent the pollution of the oil, it is important for the hydraulic system.
