Po'lat kuchlanish, kuchlanish o'lchagich va kuchlanish roliklari bo'lgan pechka
Pechning kuchlanishi
Rulda rulosining o'zini o'zi boshqarishidan foydalanish uchun chiziq boshqariladigan kuchlanish ostida o'choqdan o'tadi. Va ortiqcha o'rta kuch (asosan isitish qismida) tufayli kepçe deformatsiyasidan qoching. Har bir qismning kuchlanishi kirish yoki chiqish rulmanli rulmanda ikkita kuchlanish o'lchash birligi tomonidan alohida nazorat qilinadi. Pechdagi po'lat kamarni to'g'rilash asosan rulon turi va kuchlanishning keng qamrovli ta'siri bilan amalga oshiriladi.
Kuchlanish o'lchagich va nazorat qilish moslamasi quyidagi jadvalda keltirilgan chegara diapazonidagi kuchlanishni nazorat qilishi mumkin, ya'ni barqaror ish paytida yoki o'tish bosqichida (3 mp m / sek tezlikni cheklash) 1 foizdan yuqori boshqaruv aniqligi ({ {2}}.05 m/s2)).
