A hydrostatic rotary table is only as good as its oil supply. Understand the pump station, multi-stage filtration, temperature control, and restrictor feedback that keep the oil film stable.
Стол зависит от чистого масла под давлением 1–10 МПа через дроссели в карманы.
Чистота NAS 5+. Фильтр меняют ~каждые 500 ч, иначе частицы испортят плёнку 3–10 мкм.
Масло 35±5°C. Дроссель (особенно мембранный) сам подстраивает давление под нагрузку.
Stol phụ thuộc dầu sạch áp 1–10 MPa qua van tiết lưu vào hốc.
Sạch NAS 5+. Lọc ~500 h, nếu không hạt phá màng 3–10 μm.
Dầu 35±5°C. Tiết lưu (nhất là màng) tự chỉnh áp theo tải.
La table dépend d'une huile propre à 1–10 MPa via les restrictieurs dans les cavités.
Propreté NAS 5+. Filtre ~tous les 500 h, sinon les particules détruisent le film 3–10 μm.
Huile 35±5°C. Le restrictieur (surtout à membrane) ajuste la pression selon la charge.
Der Tisch hängt von sauberem Öl bei 1–10 MPa über Drosseln in die Taschen ab.
Reinheit NAS 5+. Filter ~alle 500 h, sonst zerstören Partikel den 3–10 μm Film.
Öl 35±5°C. Das Drosselglied (v. a. Membrane) regelt den Druck lastabhängig.
A hydrostatic rotary table does not work alone—it depends on a clean, pressurized oil supply. A pump station delivers lubricating oil at 1–10 MPa through restrictors into the table's oil cavities, where it forms the load-carrying film.
Oil cleanliness must reach NAS 5 or better. A multi-stage filter (typically serviced around every 500 hours) removes particles that would otherwise wreck the 3–10 μm film and the cavity flatness of ≤0.5 μm.
Oil is held near 35±5°C (ambient 20±1°C ideal) so the film stays dimensionally stable. The restrictor—especially membrane feedback—continuously adjusts cavity pressure as load changes, keeping stiffness high and motion precise.
