Prestasi mengikut Jenis Model<\/h3>\n
    \n
  • \n

    R622H-DGJ (Peringkat Pertama): Direka untuk tekanan masuk yang lebih tinggi sehingga 17 bar (250 PSI), dengan julat tekanan keluar 0.55 hingga 0.82 bar (8-12 PSI).<\/p>\n<\/li>\n

  • \n

    R622-DFF (Peringkat Kedua): Biasanya digunakan selepas peraturan peringkat pertama dengan tekanan masuk kira-kira 1 bar, memberikan tekanan keluar 2.24 hingga 2.94 kPa.<\/p>\n<\/li>\n<\/ul>\n

    \n

    02 Panduan Operasi dan Pelarasan<\/h2>\n

    Pemasangan dan penalaan halus Fisher R622 yang betul adalah penting untuk keselamatan dan ketahanan sistem.<\/p>\n

    Keperluan Pra-Pemasangan<\/h3>\n

    Sebelum memasang pengawal selia, pastikan paip hulu dibersihkan sepenuhnya untuk membuang serpihan dan sanga kimpalan, yang boleh merosakkan tempat duduk dan diafragma. Sentiasa sahkan bahawa arah aliran yang ditunjukkan oleh anak panah pada badan Fisher R622 sepadan dengan aliran gas sebenar dalam paip.<\/p>\n

    Langkah Pelarasan Tekanan<\/h3>\n
      \n
    1. \n

      Cari penutup plastik pelindung di bahagian atas Fisher R622 dan buka skrunya.<\/p>\n<\/li>\n

    2. \n

      Masukkan pemutar skru kepala rata ke dalam skru pelaras yang terletak di dalamnya.<\/p>\n<\/li>\n

    3. \n

      Putaran Mengikut Jam: Meningkatkan tekanan keluar.<\/p>\n<\/li>\n

    4. \n

      Putaran Lawan Jam: Mengurangkan tekanan keluar Fisher R622.<\/p>\n<\/li>\n

    5. \n

      Selepas mencapai titik set yang diingini, sahkan tekanan dengan tolok yang dikalibrasi dan pasang semula penutup pelindung.<\/p>\n<\/li>\n<\/ol>\n

      \n

      03 Protokol Penyelenggaraan dan Keselamatan<\/h2>\n

      Bagi memastikan peranti terus beroperasi dalam julat ketepatan \u00b13%, pemeriksaan berkala diperlukan. Xi'an Yunrui Trading Co., Ltd. (Yunrui) mengesyorkan jadual penyelenggaraan pencegahan berikut untuk Fisher R622:<\/p>\n

        \n
      • \n

        Kekerapan: Pemeriksaan profesional perlu dijalankan setiap 6 hingga 12 bulan, atau lebih kerap dalam persekitaran kitaran tinggi atau persekitaran yang keras.<\/p>\n<\/li>\n

      • \n

        Pengesanan Kebocoran: Gunakan larutan sabun atau pengesan elektronik untuk memeriksa sambungan ulir dan badan Fisher R622 untuk kebocoran gas.<\/p>\n<\/li>\n

      • \n

        Pemeriksaan Injap Pelega: Pastikan peranti pelega terbina dalam bebas daripada halangan, kerana ini adalah mekanisme keselamatan utama.<\/p>\n<\/li>\n

      • \n

        Penyimpanan: Untuk ketidakaktifan jangka panjang, tutup injap pengasingan, keluarkan tekanan dari Fisher R622 dan simpan di persekitaran yang bersih dan kering.<\/p>\n<\/li>\n<\/ul>\n
