ISO 4406 defines a code system for reporting particle contamination in hydraulic fluids using three numbers X/Y/Z for particles ≥4μm(c)/≥6μm(c)/≥14μm(c) per mL. Each code number represents a range of particle counts doubling with each increment.

Servo klapanlar uchun qanday maqsadli tozalik talab qilinadi?

Servo klapanlar 16/14/11 yoki undan toza talab qiladi. Proporsional klapanlar: 18/16/13. Standart yo'naltiruvchi klapanlar: 20/18/15. Tishli nasoslar: 20/18/15. Qanot nasoслари: 18/16/13. Porshenli nasoslar: 17/15/12.

β-nisbat (beta nisbat) nima?

The β-ratio (filtration ratio) is the ratio of upstream to downstream particle counts at a given size. β₁₀ = 200 means the filter removes 99.5% of particles ≥10μm. Higher β = better filtration. Per ISO 16889.

Yog' tozaligini qanday yaxshilash mumkin?

1) Yuqori β-nisbatli mayinroq filtrlar o'rnating. 2) Kidney-loop (oflayn) filtrlash qo'shing. 3) Nafas olish filtrlari bilan muhrlangan rezervuarlardan foydalaning. 4) Yangi yog'ni qo'shishdan oldin filtrlang. 5) Toza to'ldirish amaliyotidan foydalaning. 6) Kirib kelish manbalarini kamaytiring.

Yog' namunalari qanchalik tez-tez olinishi kerak?

Muhim tizimlar (servo): oyda bir marta. Standart gidravlika: har chorakda. Kam yukli tizimlar: yarim yilda bir marta. Texnik xizmatdan so'ng, suyuqlik almashtirilgandan so'ng yoki muammolar yuzaga kelganda har doim namuna oling. Namuna olishning doimiy nuqtalari va usullaridan foydalaning.

Each code number R represents a particle count range: 2^(R-1) × 0.01 to 2^R × 0.01 particles per mL (simplified). The code doubles with each increment.

Komponent bo'yicha maqsadli tozalik darajasi

Component	Maqsadli ISO kodi	Filter μm	β-ratio
Servo valves	16/14/11	3 μm	β₃ ≥ 200
Proportsional klapanlar	18/16/13	6 μm	β₆ ≥ 200
Porshenli nasoslar/motorlar	17/15/12	6 μm	β₆ ≥ 200
Vane pumps	18/16/13	10 μm	β₁₀ ≥ 200
Tishli nasoslar, standart klapanlar	20/18/15	10 μm	β₁₀ ≥ 75
Cylinders only	21/19/16	25 μm	β₂₅ ≥ 75

Amaliy Misol

Misol — Servo-klapanli tizim, hozirgi holat 20/18/15

Target: 16/14/11 → 4 kod darajasini kamaytirish kerak

Har bir kod darajasi ≈ to'g'ri filtrlash orqali 2 tizim almashinuvi

200 L system, 60 L/min flow: turnover = 200/60 = 3.3 min

Est. cleanup: 4 levels × 2 turnovers × 3.3 min ≈ 26 minutes kidney-loop filtratsiyasi
