Uglerod Tolasi Isitish Quvur Umrini Ta'sir Qiluvchi Omillar

Uglerod tolali isitish quvurlari are a novel type of electric heating element that differ from traditional metal wire heating tubes. They utilize carbon fiber as the heating element material and quartz tubes as the outer shell. Their advantages include a long service life, high electrothermal conversion rate, infrared radiation heating, acid and alkali resistance, and resistance to thermal shock. These tubes are widely used in industrial tunnel furnaces, industrial ovens, industrial dryers, and are gradually replacing halogen heating tubes and resistance wire heating tubes in household heaters.

Uglerod tolali isitish quvurlari can be categorized into many types based on their shape, quartz tube material, and processing technology. The main classification methods include:

1. Isitish elementi materiali
2. Kvarts trubkasi ichidagi gazni to'ldirish
3. Tashqi kvarts trubkasi
4. Ulanish usuli
5. Isitish naychasining umumiy shakli

Yuzdan ortiq turli nomlar bilan biz bu erda har birini sanab o'tmaymiz. Buning o'rniga biz chiziqli uglerod tolali infraqizil isitish quvurlarining ishlashi va ishlash muddatiga ta'sir qiluvchi omillarga e'tibor qaratamiz.

Currently, the most common forms of uglerod tolasi isitish elementlari include carbon felt, carbon fiber woven tape, and spiral-shaped heating wires. Each type has its advantages and applications, benefiting users in different ways.

Isitish elementi sifatida kigiz uglerod tolasidan foydalanganda quvvatning beqarorligi bilan bog'liq kichik muammolar mavjud. Bu asosan ishlab chiqarish jarayonidan kelib chiqadi, chunki uglerod tolasining o'ziga xos xususiyatlari bir xil qalinlikni ta'minlashni qiyinlashtiradi. Bundan tashqari, kesish paytida aniq nazorat qilish ham qiyinchiliklarni keltirib chiqaradi, bu esa isitish elementidagi quvvat beqarorligiga olib keladi.

Uglerod tolali to'qilgan lentani qayta ishlashda tolalar osongina tortilishi va sinishi mumkin, bu esa isitish elementining chiqishida burmalarni keltirib chiqaradi. Bu foydalanish paytida tanaffus nuqtalarida yorqin joylarni yaratishi mumkin. Biroq, spiralga to'qilgan uglerod tolasining bir nechta iplaridan foydalanish isitish elementining elektr xususiyatlarini oshirishi, sirt haroratini pasaytirishi va isitish trubasining ishlash muddatini sezilarli darajada uzaytirishi mumkin.

During the production of uglerod tolasi isitish elementlari, the carbon fiber raw yarn is first woven into ropes or tapes, then wound around a mandrel to form a spiral-shaped heating wire. After winding, the heating wire undergoes heat treatment, resulting in two types of carbon fiber heating tubes: hollow and solid (with a core rod).

Filament o'rnatilgandan so'ng yadro tayoqchasi olib tashlanadigan ichi bo'sh uglerod tolali isitish quvurlari mahkamlash jarayonida ishlatiladigan yopishtiruvchi miqdoriga katta ishonadi.

1. Ortiqcha Yopishtiruvchi:
   • Tashqi ko'rinishiga ta'sir, kvars naycha ichida ifloslanishini sabab, iflosliklarni post-issiqlik davolash yaratishingiz mumkin.
   • Isitish simini juda qattiq qiladi, bu esa tishlash yoki muhrlash kabi keyingi jarayonlarda mo'rtlik va potentsial sinish yoki shikastlanishga olib keladi.
2. Yopishqoq Etarli Emas:
   • Burrs yoki bo'shashgan iplarga olib kelishi mumkin, bu ish paytida nuqson nuqtalarida sinishga olib keladi.
   • Isitish sim uning spiral shaklini yo'qotadi va uning umrini qisqartirish, tashqi kvars naychani murojaat qilish sabab, kam qattiqlik natijalari.
3. Notekis Yopishtiruvchi:
   • Ish paytida mahalliylashtirilgan yorqin dog'larga olib keladi, bu isitish trubasining ishlash muddatiga ta'sir qiladi.

Isitish simining qalinligi isitish trubasining ishlash muddatida muhim rol o'ynaydi. Xuddi shu quvvatga ega quvurlar uchun ingichka isitish simi uglerod tolasi uzunligini va o'rash zichligini pasaytiradi, natijada ishlash muddati nisbatan qisqaroq bo'ladi. Spiralning burilish soni va balandligi kabi parametrlar ham umrga bevosita ta'sir qiladi. Optimal tanlov ishlab chiqaruvchidan amaliy tajribani talab qiladi, chunki materialdan yuqori foydalanish ishlab chiqarish tannarxini oshiradi.
