Selection and Avoidance Guide
1. Accuracy matching: The servo system needs to select a filtering ratio of β x ≥ 75, which is 10 μ m for ordinary equipment and 1-5 μ m for the aviation field.
2. Material selection: 316L stainless steel skeleton+glass fiber filter material combination, temperature resistance of 30 ℃ to 110 ℃, strong corrosion resistance. A mining case shows that the material filter element can increase the pollutant capacity by 300% under the condition of dust exceeding the standard by three times.
3. Qualification verification: Priority should be given to products certified by ISO 2941 (anti rupture) and ISO 3968 (differential pressure), which can replace imported brands.
4. Life assessment: The disposable filter element can be cycled at least 10000 times, the washable version can reach 20000 times, and the wind power special version can achieve a precision of 10 μ m.
Installation and maintenance practice
Four step method for replacing the core: After power off and oil discharge, it is necessary to disassemble and assemble in a standardized manner. Seal ring inspection and leakage testing cannot be omitted. A certain engineering team was shut down for 5 hours due to failure to tear off the protective film.
Maintenance cycle: Construction machinery should be inspected every 500 hours, while agricultural machinery should follow the "double replacement principle" simultaneously.
Fatal taboo: It is strictly prohibited to mix hydraulic oil. Dust covers are required to protect against wind speeds above level 5, which resulted in 50kg of metal particles invading a certain construction site.
