Umumiy quritgich nosozliklar ba'zi echimlarni taqdim etadi:

 

1. Ishga tushganda yo'q displey up, va kuch ko'rsatkich light da emas on: check the power line in good condition; sızdırma tuman buzuvchi o'tkazgich o'tish yo'qligini yo'q o'chirish on the back of the instrument is in the "on" position; the fuse blown.

 

2. Uzluksiz signal vaqti kuch da 3a Press the "Start" tugma in the boshlang'ich holat, agar harorat 1000 dan katta bo'lsa 1000 daraja , the thermocouple is open circuit, check the the contact in good contact.

 

3. Keyin kirish the tajriba test, the "heating" indicator on the panel on, lekin harorat ko'tarilmaydi 3a tekshirish the solid state rele.

 

4. Burilishdan so'ng quvvat ning kuchi asbob, in the non-experimental state, the o'choq harorati ko'tarilishda davom etadi qachon isitish ko'rsatkichi yorug'lik o'lchami off: o'lchov uchun o'lchov voltage bo'ylab o'choq tel, agar bo'lsa 2c bo'lsa 2c bo'lsa 220V AC voltage, the solid state relay is shikastlangan, va bir xil model almashtiriladi. Can.

 

5. Agar mavjud bo'lsa muammo hal qilingan vaqt vaqtida fog 2c iltimos bilan bog'laning ishlab chiqaruvchi vaqt.

 

1. Harorat nazorati usuli: thyristor faza o'zgarishi voltaj regulyatsiya, bilan avtomatik oqim chegarasi, overcurrent, haddan tashqari qizib ketish va boshqa himoya funktsiyalari,

 

2. Bu laboratoriya elektr o'choq harorat nazorat asbob qabul Yaponiya Shimatong aqlli asbob harorat nazorat, PID avtomatik sozlash, haddan tashqari harorat% 2c segmental ogohlantirish ogohlantirish funktsiyasi, va harorat kompensatsiya funktsiyasi, o'choq harorati harorat mos bilan mos bo'ladi harorat ko'rsatilgan asbob bilan ko'rsatiladi asbob. 40 segmentlar dasturlash mumkin.

 

3. U erda voltmetr, ammeter, quvvat ta'minoti havo o'tish, harorat nazorat asbobi, etc. panel da nazorat kabineti, va u erda tovush va yorug'lik signal qurilmalari kabi harorat va er-xotin sinishi.

Qachon foydalanilganda inert gaz sifatida ishlaydigan gaz ichida quritgich trubkasi o'choq, e'tibor uchun e'tibor 3a

 

1. ulang ishlaydigan gaz tuman, va ulang gaz chiqish tuguni ning trubasi o'choq ga mexanik nasos.

 

2. Open the air inlet valve of the atmosphere tube furnace, turn on the power of the vacuum pump, open the air outlet valve, and drain the corundum tube and gas pipeline.

 

3. Qachon truba o'choq vakuum gauge ning oxiriga yetib boradi ko'rsatkich 2c yaqin chiqish valve va yaqin inlet valve.

 

4. Turn the knob counterclockwise to open the main valve of the gas cylinder, turn the knob clockwise to slowly open the outlet pressure reducing valve.

 

5. Rotate the knob counterclockwise and slowly open the inlet valve of the tube furnace; pay close attention to the gas pressure gauge of the tube furnace.

 

6. Atmosfera trubkasi o'choq bosim o'lchagich Qachon havo bosimi barqaror bo'lsa 2c yaqin havo kirish valve of the truba o'choq, ochiq havo chiqish valf, evakuatsiya to %{{-0,1, va yopish havo chiqish valve of the tube o'choq.

 

7. Repeat steps 4-5 twice.

 

8. O'chirish mexanik nasos va ochiq havo inlet valve of the atmosphere tube furnace.
