Ekskavatorning chelak tanasi va chelak tishini payvandlash va ta'mirlash usuli

Ekskavator paqir tanasi va chelak tishini payvandlash va ta'mirlash usullari quyidagilardan iborat:

Paqir materiali va uning payvandlanishi

1. Payvandlashdan oldin payvandlash joyini tozalang

Bu asl yorilish payvandlash go'shtini olib tashlash, fazali maydalagichni silliqlash yoki uglerod yoyi havo tekisligidan shartli foydalanish bilan, lekin tekislik toza temir oksidi bilan sayqallanishi kerak.

2. Payvandlashdan oldin oldindan isitishni amalga oshirish kerak

Iloji bo'lsa, payvandlash joyini 100 gradusgacha oldindan qizdiring.Keyin payvandlash uchun 3,2J507 diametrli payvandlash tayog'idan foydalaning va qisqa vaqtdan keyin payvandlashni to'xtating.Payvand choki va chokning chetiga urish uchun bolg'achadan foydalaning.Payvandlash tugallangandan so'ng, payvand choki asosan sovib ketguncha bolg'acha bilan uring.Maqsad payvand choki kuchlanishini bo'shatishdir, chunki payvandlashdan keyingi issiqlik bilan ishlov berish mumkin emas.

3. Payvandlash uchun mos payvandlash materiallari tanlanishi kerak

Elektrod turi muhim ahamiyatga ega.Agar siz temir ko'pik testini o'tkazishingiz kerak bo'lgan materialning qanday turini tushunishni istasangiz, sinov chiqdi va keyin elektrodning chiziqdagi taqsimotiga ko'ra.

4. Ekskavatorning chelak tanasi va chelak tishini payvandlash to'liq payvandlangan bo'lishi kerak

Payvandlashda payvand chokining kirib borishini ta'minlash kerak, agar payvand choki bo'shlig'i orqa plastinka ichida katta bo'lishi mumkin bo'lsa.
