Bepul muhandislik vositasi — #028
Texnik holat monitoringi — ISO 13373
ISO 13373 texnik holat monitoringi parametrlari uchun ma'lumotnoma vositasi. Mashina turini tanlang va ogohlantirish hamda xavf chegaralariga nisbatan holatni aniqlash uchun o'lchangan tebranish qiymatini kiriting.
Assessment
ISO 10816 tebranish amplitudasi zonalari
Tebranish amplitudasi to'rtta zonaga bo'linadi:
- Zone A — Yangi yoki ta'mirlangan mashinalar
- Zone B — Uzoq muddatli uzluksiz ishlatish uchun maqbul
- Zone C — Ogohlantirish — faqat cheklangan vaqt davomida maqbul
- Zone D — Xavfli — shikast yetkazishi mumkin
Tezlik chegaralari (mm/s RMS)
Per ISO 10816-3 (now ISO 20816-3): Group 1 — large industrial machines >300 kW–50 MW; Group 2 — medium machines 15–300 kW. Each group is evaluated separately for rigid or flexible support conditions.
| Zone Boundary | Group 1 — Rigid | Group 1 — Flexible | Group 2 — Rigid | Group 2 — Flexible |
|---|---|---|---|---|
| A/B | 2.3 | 3.5 | 1.4 | 2.3 |
| B/C (Alarm) | 4.5 | 7.1 | 2.8 | 4.5 |
| C/D (Danger) | 7.1 | 11.0 | 4.5 | 7.1 |
Bazaviy monitoring
A change ratio > 2.5× baseline suggests developing fault. > 4× requires immediate investigation.
ℹ️ Note: Group 1/2 boundaries are from ISO 10816-3 (now ISO 20816-3). Small-machine (<15 kW) values follow general ISO 10816-1 guidance — such machines are outside the scope of Part 3. Specific machine types may have different criteria per specialized parts of ISO 20816.
Mashinalar holatini professional tebranish analizatorlari yordamida nazorat qiling. ISO standartlariga muvofiq o'lchov va hisobot. 50 dan ortiq mamlakatda qo'llaniladi.
