lampu kalis letupan Suhu persekitaran merujuk kepada suhu udara atau medium lain yang mengelilingi peralatan atau komponen.<\/p>\n\n\n\n

Di bawah keadaan biasa, suhu persekitaran untuk operasi peralatan hendaklah -20 hingga 40 \u2103. Dalam kes sedemikian, tiada penandaan suhu persekitaran tambahan diperlukan. Walau bagaimanapun, apabila peralatan dijangka digunakan dalam persekitaran di luar julat suhu ini, ia dianggap sebagai situasi khas. Penandaan hendaklah merangkumi simbol Ta atau Tamb bersama had atas dan bawah suhu persekitaran. Jika ini tidak dapat dilaksanakan, simbol \u201cX\u201d hendaklah menunjukkan keadaan operasi khas termasuk had atas dan bawah suhu persekitaran. Ini bermakna bahawa secara amnya, keperluan suhu persekitaran -20 hingga 40 \u2103 untuk peralatan tidak perlu ditandakan pada pelat nama atau sijil kalis letupan. Tetapi jika peralatan itu dimaksudkan untuk digunakan dalam julat suhu persekitaran selain daripada ini, ia mesti dinyatakan pada plat nama produk dan sijil, serta dinyatakan dalam manual pengguna.<\/p>\n\n\n\n

Apakah keperluan khas suhu persekitaran untuk peralatan elektrik kalis api dan lampu kalis letupan?<\/p>\n\n\n\n

Pertama, suhu rendah memberi kesan kepada tekanan letupan, dan peraturan yang berkaitan adalah:<\/p>\n\n\n\n

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

Apabila suhu persekitaran berada di bawah -20 \u2103, tekanan rujukan hendaklah diukur menggunakan kaedah suhu rendah atau kaedah prapengisian tekanan. Tekanan rujukan yang diperoleh dengan cara ini jauh lebih tinggi berbanding yang diukur pada suhu dan tekanan biasa. <\/p>\n\n\n\n

Oleh itu, keperluan kekuatan bagi sarung peralatan elektrik dalam persekitaran suhu rendah adalah lebih tinggi, dan perkara ini perlu diambil kira semasa proses reka bentuk.<\/p>\n\n\n\n

Kedua, pengaruh suhu tinggi terhadap ujian pencegahan penyebaran penyalaan dalaman dan peraturan yang berkaitan:<\/p>\n\n\n\n

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

Iaitu, apabila suhu persekitaran melebihi 60 \u2103, ujian pencegahan penyebaran percikan dalaman hendaklah dijalankan melalui suhu tinggi atau pra-penekanan. Tekanan letupan yang terhasil dengan cara ini adalah lebih tinggi berbanding pada suhu dan tekanan biasa. <\/p>\n\n\n\n

Peralatan yang boleh lulus ujian pada suhu dan tekanan biasa mungkin tidak lulus ujian pencegahan penyebaran nyalaan dalaman di bawah pra-penekanan. Ini meletakkan keperluan yang lebih tinggi terhadap panjang, jurang dan kekuatan kulit permukaan sambungan kalis api pada peralatan kalis api yang digunakan dalam persekitaran suhu tinggi. Faktor-faktor ini perlu diambil kira semasa proses reka bentuk.<\/p>","protected":false},"excerpt":{"rendered":"
