Elektr isitish trubkasining sirt harorati bu trubka tanasiga elektr energiyasidan keyin magnezium oksidi kukuni bilan to'ldirilgan isitish trubkasi orqali isitish simi orqali hosil bo'ladigan issiqlikdir, keyin isitish trubasining yuzasi haroratga ega, sirt haroratini qanday bilishimiz mumkin elektr isitish trubkasi?
Elektr isitish trubkasining sirt harorati elektr isitish trubkasining sirt yuki bilan, elektr isitish trubkasining sirt yuki esa elektr isitish trubasining yuzasi va kuchi bilan aniqlanadi.
Avvalo, biz elektr isitish trubkasining sirt yuki nima ekanligini bilishimiz kerak. Yuzaki yuk elektr isitish elementi yuzasida birlik maydoni tomonidan taqsimlanadigan quvvat sonini bildiradi, u Vt / sm2 bilan ifodalanadi.
Yuzaki yukni hisoblash formulasi: quvvat Vt / [quvur diametri (sm) * 3.14 * L (sm)]
(1) Statik havo
Sirtdagi yuk 1W / sm2 ga yetganda, isitish trubasining sirt harorati 300 darajaga yetishi mumkin;
Sirtdagi yuk 2W / sm2 ga yetganda, isitish trubasining sirt harorati 420 darajaga yetishi mumkin;
Sirtdagi yuk 3W / sm2 ga yetganda, isitish trubasining sirt harorati 500 darajaga yetishi mumkin;
Sirtdagi yuk 4W / sm2 ga yetganda, isitish trubasining sirt harorati 580 darajaga yetishi mumkin.
Sirtdagi yuk 5W / sm2 ga yetganda, isitish trubasining sirt harorati 630 darajaga yetishi mumkin.
Sirtdagi yuk 6W / sm2 ga yetganda, isitish trubasining sirt harorati 680 darajaga yetishi mumkin.
