Uzun payvandlash bo'yinli

Lwn flane nima?

"Lwn flanje" atamasi payvandlash bo'yinining uzoqroq versiyasini anglatadi. Payvandlash ulanishlari uchun kaptarlar bilan, payvandlangan bo'yinbangka o'xshash uyaga ega, ammo u uzunroq va to'g'ri, kesishmaydi.

Uzoq payvand chok fleyeslari odatda sinf plitalarida ishlatiladi. DN50 o'lchamidagi yoki teng bo'lgan trubka, uzun baland bo'yli fleptalar yordamida, uzun bo'yli flang'ichlardan foydalanib, uzoq bo'yli devor qalinligida juda nozik devor qalinligidan kelib chiqadigan payvandlash muammolarini minimallashtirishga yordam beradi.

Xususiyatlari:

Kengaytirilgan uy:LWN Vashilning markazi uzunligi va yuk ko'tarish qobiliyatini yaxshilaydi va quvur liniyasi bilan yaxshiroq payvandlanishi mumkin

Butt payvandlash:To'g'ri markaz payvandlash flanjesi odatda, tokin payvandlash bilan jihozlangan va payvand choklari flakon yuzasidan uzoqroq, bu payvandlash paytida flanje yuzasidan juda uzoqda

XUB oxiri:Bevelssiz

LWN Flanjes va Wn Flaes o'rtasidagi farq nima?

Strukturaviy dizayn:

Lwn uzunroq va shtamptik xub bor; Uyaning oxiri tekis va aralashma yo'q

WN: uya qisqa va xiralashgan; Bo'yinning oxiri hajmi bor

Ariza muhiti:

Lwn: Qattiq mehnat muhiti, masalan, yuqori haroratli va past haroratga chidamliligi kabi

WN: Bosim yoki haroratda yoki yuqori haroratli, yuqori bosimli va past haroratli quvurlarda katta tebranishlar bilan quvurlar uchun mos keladi

Afzalliklari:

Lwn: uzun bo'yin dizayni ulanishning barqarorligi va muhrini kuchaytiradi va quvurlarni ta'mirlash, kuchaytirish va korroziyadan himoya qilish uchun yaxshi sharoitlar ham ta'minlaydi; oson o'rnatish

WN: Deforing, yaxshi muhrlash oson emas; chiroyli ko'rinishi, silliq sirt

Kamchiliklari:

LWN: Katta payvandlash ish yuki, payvandlash novdalarini yuqori iste'mol qilish; Yuqori harorat va yuqori bosimga, takroriy egilish va haroratda o'zgaruvchan bo'lmaydi. Bu ko'proq bo'sh joyni egallaydi, bu tor bo'sh joylarda foydalanish noqulay holga keltiradi

WN: Payvandlash jarayoni va sifatli quvurlar ulanishlarining qat'iyligini ta'minlash va sifatini ta'minlash uchun yuqori talablar
