1. Oil return hydraulic oil <br>filter The main function of hydraulic oil filter is to filter oil, and various impurities will inevitably appear in the hydraulic system. The main sources are: mechanical impurities remaining in the hydraulic system after cleaning, such as scale, casting sand, welding slag, iron filings, paint, paint and cotton yarn scraps, etc., and impurities that enter the hydraulic system from outside, such as through the fuel filler and Dust that enters the dust ring, etc.; impurities generated during the working process, such as the fragments formed by the hydraulic action of the seal, the metal powder generated by the relative wear of the movement, the gum, asphaltene, carbon residue, etc. generated 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, they will cause damage everywhere, which will seriously affect the normal operation of the hydraulic system, such as small gaps between relatively moving parts in the hydraulic components, as well as throttle holes and gaps. Stuck or blockage; destroy the oil film between the 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. According to production statistics, more than 75% of the faults 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 oil return hydraulic oil filter is installed on the oil return pipeline. This installation method can frequently remove impurities in the oil. In order to prevent the oil filter from being blocked, the oil can still flow back to the oil tank smoothly. Due to the low pressure of the oil return pipe, a low-strength oil filter can be used.

1, return oil hydraulic filter<br>The main function of hydraulic oil filter is to filter the fluid, and various impurities inevitably appear in the hydraulic system. Its main sources are: after cleaning still remain in the hydraulic system of mechanical impurities, such as water rust, cast sand, solder slag, iron chips, paint, paint skin and cotton yarn chips, external impurities into the hydraulic system, such as through the fuel port and dust ring, such as dust entered by the process of impurities, such as seals formed by hydraulic action debris, the movement of metal powder produced by relative wear, oil due to oxidation, gel, asphalt, etc. After the above impurities are mixed into the hydraulic oil, with the circulation of hydraulic oil, it will be everywhere destructive, seriously affecting the normal work of the hydraulic system, such as making the hydraulic components between the relative moving parts of the small gap and thymosive holes and gaps stuck or blocked; According to production statistics, more than 75% of the failures in the hydraulic system are caused by the mixing of impurities in the hydraulic oil, so it is important for the hydraulic system to maintain the cleaning of the fluid and prevent contamination of the fluid. The return hydraulic filter is installed on the return pipe, which often removes impurities from the fluid. In order to prevent the filter from clogging, the fluid can still flow smoothly back to the tank. Due to the low return line pressure, a lower strength filter can be used.

The main sources are: the mechanical impurities remaining in the hydraulic system after cleaning, such as water rust, casting sand, welding slag, iron filings, coatings, paint skin and cotton yarn filings; the external impurities entering into the hydraulic system, such as the dust entering through the oil filler and dust ring; the impurities produced in the working process, such as the fragments formed by the hydraulic action of the seals, and the gold produced by the relative wear during the movement It belongs to powder, colloid, asphaltene and carbon residue produced by oxidation of oil. After the above impurities are mixed into the hydraulic oil, with the circulation of the hydraulic oil, they will play a destructive role everywhere, seriously affecting the normal work of the hydraulic system, such as making the small gap between the relative moving parts in the hydraulic components and the throttle hole and gap stuck or blocked; destroying the oil film between the relative moving parts, scratching the surface of the gap, increasing the internal leakage, reducing the efficiency and increasing the efficiency Heat aggravates the chemical action of the oil and causes the oil to deteriorate. According to the production statistics, more than 75% of the faults in the hydraulic system are caused by impurities in the hydraulic oil. Therefore, it is very important for the hydraulic system to maintain the cleanness of the oil and prevent the pollution of the oil. The oil return hydraulic filter is installed on the oil return pipeline, which can often remove the impurities in the oil. In case of oil filter blockage, the oil can still flow back to the oil tank smoothly. Due to the low pressure of oil return pipe, the oil filter with lower strength can be used.<br>
