Quruq olovli elektr isitish quvurlarining sirt harorati

Elektr isitish trubasining sirt harorati isitish trubkasi ichiga to'ldirilgan magniy oksidi kukuni orqali o'tadigan va kolba tanasidan o'tadigan elektr simidan hosil bo'lgan issiqlikdir. Bu vaqtda isitish trubasining yuzasi haroratga ega. Elektr isitish trubasining sirt haroratini qanday bilishimiz mumkin?
Elektr isitish trubasining sirt harorati uning sirt yuki bilan belgilanadi, bu esa o'z navbatida uning sirt maydoni va quvvati bilan belgilanadi.
Birinchidan, biz elektr isitish trubasining sirt yuki nima ekanligini bilishimiz kerak. Sirt yuki Vt / sm2 da ifodalangan isitish elementining yuzasi tomonidan taqsimlangan maydon birligi uchun quvvat miqdorini bildiradi.
Sirt yuki uchun hisoblash formulasi: Quvvat Vt/[Quvur diametri (sm) * 3,14 * L (sm)]
(1) Havo
Sirt yuki 1W / sm2 ga yetganda, isitish trubasining sirt harorati 300 darajaga yetishi mumkin;
Sirt yuki 2W / sm2 ga yetganda, isitish trubasining sirt harorati 420 darajaga yetishi mumkin;
Sirt yuki 3W / sm2 ga yetganda, isitish trubasining sirt harorati 500 darajaga yetishi mumkin;
Sirt yuki 4W / sm2 ga yetganda, isitish trubasining sirt harorati 580 darajaga yetishi mumkin;
Sirt yuki 5W / sm2 ga yetganda, isitish trubasining sirt harorati 630 darajaga yetishi mumkin;
Sirt yuki 6W / sm2 ga yetganda, isitish trubasining sirt harorati 680 darajaga yetishi mumkin;
