Dikenali umum bahawa prestasi perlindungan sarung peralatan yang dilindungi oleh sarung kalis habuk dan kalis letupan \u201ct\u201d adalah titik utama yang menjadi tumpuan reka bentuk produk. Oleh itu, rasionaliti struktur gasket dan penyegel yang berperanan melindungi adalah amat penting. <\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

I. Keperluan Struktur <\/p>\n\n\n\n

Pada permukaan penyambungan, gasket mampat boleh digunakan untuk memastikan keberkesanan meterai petak. Semua gasket dan meterai hendaklah mempunyai struktur bersepadu dan berterusan, iaitu berbentuk cincin dan tidak terputus. Struktur petak hendaklah memastikan kedudukan gasket yang betul. <\/p>\n\n\n\n

Jika darjah perlindungan petak bergantung pada gasket pada sambungan petak dan sambungan itu perlu dibuka semasa pemasangan atau penyelenggaraan, gasket hendaklah dilekatkan atau dipasang secara mekanikal pada salah satu permukaan yang bersambung untuk mengelakkan kehilangan, kerosakan atau pemasangan yang salah. Permukaan yang bersambung yang menggunakan gasket tidak seharusnya menggunakan bahan penyegel tambahan sebagai kaedah bantu untuk prestasi penyegelan. <\/p>\n\n\n\n

Engsel tidak boleh digunakan sebagai cara untuk mengekalkan meterai, kecuali dalam kes di mana gasket boleh dimampatkan dengan betul tanpa menyebabkan pergerakan tidak dijangka, tegasan atau deformasi pada gasket. <\/p>\n\n\n\n

Segel fleksibel, seperti bellows, tidak seharusnya dikenakan tekanan berlebihan pada mana-mana bahagian. Langkah-langkah perlu diambil untuk mengelakkan kerosakan mekanikal luaran, dan setiap hujungnya perlu dipasang secara mekanikal. <\/p>\n\n\n\n

Nota: Keperluan di atas tidak terpakai kepada meterai dalam peranti kemasukan kabel. <\/p>\n\n\n\n

II. Keperluan Ujian <\/p>\n\n\n\n

Selepas menjalankan ujian sarung mengikut keperluan yang berkaitan, ujian tekanan hendaklah dijalankan ke atas semua sampel ujian, diikuti dengan ujian gred perlindungan IP. <\/p>\n\n\n\n

Standard bagi \u201cPeralatan Dilindungi oleh Sarung Kalis Pembakaran Debu \u2018t'\u201d dalam persekitaran letupan telah menambah keperluan ujian tekanan untuk menilai kesan pelindung gasket dan pengedap. Secara khusus, tekanan dalaman hendaklah sekurang-kurangnya (4 \u00b1 0.4) kPa (untuk tahap perlindungan \u2018ta\u2019) dan (2 \u00b1 0.2) kPa (untuk tahap perlindungan \u2018tb\u2019 dan \u2018tc\u2019), berlangsung selama 60 hingga 70 saat. <\/p>\n\n\n\n

Perlu diambil perhatian di sini bahawa:<\/p>\n\n\n\n

(a) Peranti pengenalan kabel dan petak tambahan peralatan Ex tidak perlu menjalani ujian tekanan, kecuali gasket penyegel yang memberikan perlindungan pada permukaan sendi pemasangan peranti pengenalan dan petak tersebut; <\/p>\n\n\n\n

(b) Jika struktur peralatan Ex boleh mengehadkan pergerakan gasket dan segel, seperti cincin \u201cO\u201d dalam alur atau gasket penyegelan yang melekat pada satu sisi permukaan sambungan, ujian tekanan tidak diperlukan untuk peralatan Ex dengan tahap perlindungan \u201ctb\u201d dan \u201ctc\u201d.<\/p>","protected":false},"excerpt":{"rendered":"
