Harorat o'tkazish
Barcha ichki ma'lumotlar °C da saqlanadi. Celsius va Fahrenheit orasidagi o'tkazish:
Holat chegaralari
- OK (Green): o'lchangan harorat maksimal doimiy chegaraning 80% dan pastida
- Ogohlantirish (Sariq): o'lchangan harorat maksimal doimiy chegaraning 80% va 100% oralig'ida
- Danger (Red): o'lchangan harorat maksimal doimiy chegaradan oshib ketgan
Amaliy Misol
Given: Tashqi korpusda 105 °C haroratda o'lchangan standart po'lat sharli podshipnik.
Max continuous = 120 °C, max short-term = 150 °C
Measured 105 °C = 87.5% of max continuous → Warning zone (80–100%)
Actual inner raceway temp is likely 115–125 °C (10–20 °C higher than housing)
Recommendation: Issiqlik chegarasiga yaqinlashilmoqda. Asosiy sababni aniqlang — moylanishning yomonlashishi, noto'g'ri o'rnatish (misalignment) yoki ortiqcha yuk bo'lishi mumkin.
💡 Tip: Nominal haroratdan har 15 °C oshishi uchun podshipnik resursi taxminan ikki baravar kamayadi. Haroratni monitoring qilish eng samarali profilaktik texnik xizmat ko'rsatish vositalaridan biridir.
Professional ko'chma balansirovka asboblari, tebranish analizatorlari va holat monitoringi tizimlari. Tebranish tahlili yordamida qizib ketayotgan podshipniklarni erta aniqlang. 50+ mamlakatda qo'llaniladi.
