A hydrostatic oil film is only 3–10 μm thick, so particles larger than that wreck it. Maintaining NAS 5 cleanliness and timely filter service is the single most important upkeep task.
Толщина плёнки 3–10 мкм. Частица крупнее может пробить плёнку и испортить поверхность.
Чистота NAS 5+. Фильтр меняют ~каждые 500 ч.
Чистое масло бережёт дроссели, карманы (плоскостность ≤0,5 мкм) и плёнку. Пропуск фильтра губит ресурс.
Màng dày 3–10 μm. Hạt lớn hơn có thể thủng màng, xước mặt.
Sạch NAS 5+. Lọc thay ~500 h.
Dầu sạch giữ van tiết lưu, hốc (phẳng ≤0,5 μm) và màng. Bỏ lọc là hỏng nhanh.
L'épaisseur du film est de 3–10 μm. Une particule plus grosse perce le film et raye la surface.
La propreté doit atteindre NAS 5 ou mieux. Le filtre est changé environ tous les 500 h.
L'huile propre protège restrictieurs, cavités (planéité ≤0,5 μm) et film. Sauter le filtre ruine la durée de vie.
Die Filmdicke liegt bei 3–10 μm. Ein größeres Teilchen kann den Film brechen und die Fläche zerkratzen.
Die Reinheit sollte NAS 5 oder besser sein. Der Filter wird etwa alle 500 Betriebsstunden getauscht.
Sauberes Öl schützt Drosseln, Taschen (Planheit ≤0,5 μm) und den Film. Filter sparen zerstört die Lebensdauer.
The design oil-film thickness in a precision hydrostatic component is just 3–10 μm—far thinner than a human hair. A single particle larger than the gap can breach the film, score the surface, and destroy accuracy.
Oil cleanliness should reach NAS 5 or better. Multi-stage filtration removes particles, and the filter element is typically replaced around every 500 hours of operation to keep the oil within spec.
Clean oil protects the restrictors, the oil cavities (whose flatness must stay ≤0.5 μm), and the film itself. Skipping filtration is the fastest way to turn a theoretically infinite-life bearing into a worn one.
