What is the composition of the hydraulic oil filter device, its basic function and how to maintain it?


The hydraulic oil filter device of the horizontal waste paper baler generally mainly refers to the oil cylinder filter screen. The basic maintenance of the oil cylinder is to ensure that the oil cylinder is sealed and the periphery is clean.


According to after-sales statistics, more than 75% of the failures in the hydraulic system are caused by impurities mixed in the hydraulic oil. Therefore, maintaining the cleanliness of the oil and preventing the contamination of the oil are very important for the hydraulic system.


The function of the hydraulic filter is to filter various impurities in the hydraulic oil. The main sources of impurities are:


Mechanical impurities still remaining in the hydraulic system after cleaning, such as scale, sand casting, welding slag, iron filings, paint, paint leather and cotton yarn scraps, etc., and impurities that enter the hydraulic system from the outside, such as through the oil filler and dust ring, etc. Incoming dust; impurities generated during the working process, such as the fragments formed by the hydraulic pressure of the seal, the metal powder produced by the relative wear of the movement, the gum, asphaltene, and carbon residue produced by the oil due to oxidative deterioration.


After the above-mentioned impurities are mixed into the hydraulic oil, with the circulation of the hydraulic oil, it will cause damage everywhere, which will seriously affect the normal operation of the hydraulic system, such as making the small gap (in μm) between the relatively moving parts in the hydraulic component and the joint Flow orifices and gaps are stuck or blocked; damage the oil film between relative moving parts, scratch the surface of the gap, increase internal leakage, reduce efficiency, increase heat generation, aggravate the chemical action of the oil, and make the oil deteriorate.
