Ufuatiliaji wa Hali — ISO 13373
Zana ya kumbukumbu kwa vigezo vya ufuatiliaji wa hali vya ISO 13373. Chagua aina ya mashine na weka thamani ya mtetemo iliyopimwa ili kubaini hali dhidi ya vipimo vya onyo na hatari.
Assessment
Kanda za Ukali wa Mtetemo kulingana na ISO 10816
Ukali wa mtetemo hugawanywa katika kanda nne:
- Zone A — Mashine mpya au zilizofanyiwa ukarabati
- Zone B — Inakubalika kwa uendeshaji wa muda mrefu bila vikwazo
- Zone C — Tahadhari — inakubalika kwa muda mfupi tu
- Zone D — Hatari — inaweza kusababisha uharibifu
Viwango vya Kasi ya Mtetemo (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 |
Ufuatiliaji wa Kipimo cha Msingi
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.
Fuatilia hali ya mashine kwa kutumia vichunguzi vya mtetemo vya kitaalamu. Kipimo na ripoti zinazokidhi viwango vya ISO. Zinatumika katika nchi zaidi ya 50.
