The Fisher 657<\/a> va Fisher 667<\/a> Ushbu seriya prujinali diafragma aktuatorlari uchun sanoat standartini ifodalaydi. Ushbu pnevmatik aktuatorlar turli xil kontroller yoki pozitsioner chiqish signallariga javoban klapan vilkasi tayoqchalarini joylashtirish uchun mo'ljallangan. Ikkalasi ham mustahkamlik va ishonchlilik bo'yicha obro'ga ega bo'lsa-da, ularning operatsion yo'nalishi va mexanik konfiguratsiyalari sohada alohida xavfsizlik funktsiyalarini bajaradi. Jarayon muhandislariga to'g'ri tanlash va texnik xizmat ko'rsatishda yordam berish uchun Xi'an Yunrui Trading Co., Ltd. (Yunrui) ushbu batafsil texnik tahlilni taqdim etadi.<\/p>\n

\n01 Texnik farqlar: Harakat va konfiguratsiya<\/h2>\n

Ikki model o'rtasidagi asosiy farq havo bosimi va poyaning harakati o'rtasidagi bog'liqlikda.<\/p>\n

    \n
  1. \n

    Fisher 657 (To'g'ridan-to'g'ri ta'sir): Ushbu konfiguratsiyada yuqori diafragma plastinkasida havo bosimining ortishi aktuator dastasini pastga itaradi. Havo bosimi pasayganda, ichki prujina dastani yuqoriga ko'tarishga majbur qiladi.<\/p>\n<\/li>\n

  2. \n

    Fisher 667 (Teskari harakat): Pastki diafragma plastinkasidagi havo bosimining ortishi aktuator dastasini prujinaga qarshi yuqoriga itaradi. Havo bosimi pasayganda, prujina dastani pastga majbur qiladi.<\/p>\n<\/li>\n<\/ol>\n\n\n\n\n\n\n\n\n

    \n02 Operatsion tamoyillar va kuchlar muvozanati<\/h2>\n

    Fisher 657 va Fisher 667 ikkalasi ham pnevmatik energiyani chiziqli harakatga aylantirish uchun egiluvchan diafragma va qoliplangan diafragma plastinkasidan foydalanadi.<\/p>\n

    Poyani harakatlantirish uchun mavjud bo'lgan umumiy kuch pnevmatik kuch (bosim diafragma maydoniga ko'paytiriladi) va qarama-qarshi prujina kuchi o'rtasidagi farqdir. Xi'an Yunrui Trading Co., Ltd. (Yunrui) muhandislari to'g'ri prujina tezligini tanlash juda muhimligini ta'kidlaydilar, chunki u dastgoh to'plamini va aktuatorning klapan o'rindig'i ishqalanishi va suyuqlik kuchlarini yengish qobiliyatini belgilaydi.<\/p>\n

    \n

    03 Texnik xizmat ko'rsatish va ta'mirlash tartiblari<\/h2>\n

    Havo oqishining oldini olish va klapanlarning aniq joylashishini ta'minlash uchun muntazam texnik xizmat ko'rsatish juda muhimdir. Xi'an Yunrui Trading Co., Ltd. (Yunrui) sizning Fisher aktuatorlaringizga xizmat ko'rsatish uchun quyidagi amallarni tavsiya qiladi.<\/p>\n

    Ogohlantirish: Demontaj qilishdan oldin, aktuator chetlab o'tilganligiga va barcha havo bosimi tugaganligiga ishonch hosil qiling. Prujina sezilarli darajada siqilgan; korpus murvatlarini bo'shatishda ehtiyot bo'ling.<\/p>\n

      \n
    1. \n

      Diafragma tekshiruvi: Yoriqlar, qotib qolishlar yoki yirtilishlarni tekshiring. Shikastlangan diafragma Fisher 657 va Fisher 667 da javob bermaslikning asosiy sababidir.<\/p>\n<\/li>\n

    2. \n

      Poya muhrini ta'mirlash: Poya ulagichlari va harakatlanish ko'rsatkichlarini a\u015f\u0131nma yoki noto'g'ri hizalanish belgilari bor-yo'qligini tekshiring.<\/p>\n<\/li>\n

    3. \n

      Prujinani tekshirish: Prujina charchagan yoki korroziyaga uchramaganligiga ishonch hosil qiling. Prujinaning ishlamay qolishi dastgoh to'plamini siljitadi, bu esa boshqaruv aniqligining pasayishiga olib keladi.<\/p>\n<\/li>\n

    4. \n

      Moylash: Silliq harakatlanishni ta'minlash uchun aktuator dastasiga va prujina sozlagichining rezbalariga yuqori sifatli moylash materialini surting.<\/p>\n<\/li>\n<\/ol>\n

      \n
