Penapis pengekstrak wasap laser: bila perlu tukar dan cara membeli

Unit pengekstrak di sebelah laser jarang dipandang sehingga bau merebak ke seluruh kilang. Masa untuk tukar bukan ditentukan kalendar, tetapi satu angka.Apa sebenarnya yang menyumbat penapisPenandaan laser tidak menghasilkan habuk biasa, tetapi jelaga bersaiz bawah mikron bersama sebatian organik meruap. Kedua-duanya menyumbat penapis melalui laluan berbeza: zarah membentuk lapisan pada permukaan media penapis sehingga udara semakin sukar menembusi, manakala sebatian organik diserap karbon aktif, dan apabila tepu ia tidak memberi apa-apa isyarat, hanya berhenti berfungsi secara senyap. Pada satu barisan, kedua-dua punca wujud serentak tetapi biasanya muncul dalam urutan berbeza. Semasa menanda filem pembungkusan, beban zarah tinggi dan media penapis menyerah dahulu. Semasa menanda logam, zarah sedikit tetapi bau lebih tajam, dan biasanya karbon tepu lebih awal. Kenal pasti kes anda, arah penggantian jadi jelas. Satu butiran yang sering diabaikan: penapis awal wujud untuk menerima hentaman pertama. Jika ia hitam sepenuhnya dalam tiga bulan, hayat penapis utama bergantung sepenuhnya pada kekerapan anda menukar penapis awal, bukan kapasiti penapis utama.Lihat penurunan tekanan, bukan kalendarSetiap pengekstrak mempunyai tolok penurunan tekanan, biasanya jenis mekanikal. Jarumnya duduk di bawah dan tiada siapa memandangnya. Cara betul ialah catat bacaan semasa penapis bersih pada hari pentauliahan, masukkan ke dalam fail peralatan, dan sentiasa bandingkan dengan asas itu. Berdasarkan pengalaman, apabila penurunan tekanan naik sekitar satu setengah kali asas, alat ganti patut disediakan. Apabila mencecah dua kali, aliran udara jelas tidak mencukupi dan bau mula keluar ke kawasan kerja. Menukar pada ketika ini bermakna minggu atau dua sebelumnya barisan telah beroperasi melebihi had, cuma tiada siapa menyedunya. Ada juga kes penurunan tekanan tidak naik langsung, iaitu tepu karbon. Udara mengalir lancar tetapi keupayaan penjerapan sudah habis. Di sini keputusan dibuat berdasarkan bau, atau anggaran daripada jisim penjerap dan jam operasi, ambil mana yang tiba dahulu.Padankan penapis ganti dengan mesinPenapis ganti mesti padan pada tiga dimensi: aliran udara terkadar, kelas penapisan dan ukuran selongsong. Dua yang pertama menentukan hasil, yang ketiga menentukan sama ada ia boleh masuk. Punca kebanyakan aduan bukan media penapis, tetapi penapis yang beza satu setengah sentimeter, dipaksa masuk, menyebabkan pengedapan sekeliling gagal dan wasap memintas melalui celah. Dari segi aliran udara, lebih baik berlebihan daripada terlalu rapat. Elemen yang terkadar dua puluh peratus bawah keperluan mesin pada mulanya masih berfungsi, tetapi penurunan tekanan naik jauh lebih pantas dan hayat susut melebihi perbezaan harga. Dari segi kelas penapisan, untuk wasap laser lazimnya H13, keperluan sebenar bergantung pada peraturan tempatan dan persekitaran kilang. Kedudukan pemasangan dan rangka juga patut dilihat. Bagi siri pengekstrak yang sama, alur antara kelompok boleh berubah sedikit, terutama mesin yang telah digunakan tiga hingga lima tahun. Lebih selamat bertanya dengan plat nama mesin dan model pengekstrak, bukan hanya ukuran penapis. Penyimpanan alat ganti dan bahan guna habis berkait rapat. Banyak kilang menggabungkan penapis pengekstrak dengan dakwat, pelarut dan cip kepada satu pembekal, bukan empat pesanan dengan empat tarikh penghantaran. Di TOPMARK kami meletakkan penapis pengekstrak bersama bahan guna habis penanda dalam satu senarai dan merancang secara suku tahunan, lebih stabil daripada pesanan berpecah.Mengapa penapis murah lebih mahal pada barisan laserMasalah penapis murah bukan pada harganya, tetapi pada lengkung penurunan tekanan yang sangat curam. Dalam keadaan sama, elemen berkualiti boleh bertahan enam bulan manakala lipatan murah mencecah had dalam dua bulan. Setiap penggantian tambahan bukan sekadar harga penapis, tetapi juga henti mesin, buka pasang, kos buruh dan pelupusan sisa; jumlahnya hampir selalu melebihi perbezaan harga. Bagi karbon lebih ketara. Karbon dengan nombor iodin tidak mencukupi mungkin hanya separuh keupayaan penjerapan dan tidak memberi isyarat apabila tepu. Pada barisan yang berisiko menerima aduan bau, kos tersembunyi ini akan kembali melalui jalan lain lambat laun. Dan jangan menyimpan berlebihan. Penapis yang lembap kehilangan ketegaran media dan keupayaan penjerapan, karbon khususnya sensitif terhadap kelembapan. Simpan dalam bungkusan asal yang tertutup, bukan di atas lantai, dengan kelembapan bawah enam puluh peratus. Bungkusan yang dibuka elok dipasang terus daripada dibiar terbuka di kilang.Rekod yang menjimatkan keputusan seterusnyaYang benar-benar menjimatkan masa bukan mengingati berapa kali ditukar, tetapi rekod yang membolehkan orang seterusnya membuat keputusan terus. Sekurang-kurangnya empat perkara: tarikh pemasangan, penurunan tekanan ketika itu, sebab penggantian (had tekanan atau bau berlebihan) dan jam operasi sebenar elemen tersebut. Selepas tiga atau empat elemen, selang sebenar barisan anda akan kelihatan, dan irama pembelian serta kuantiti simpanan boleh ditetapkan tanpa meneka. Jauh lebih boleh dipercayai daripada menganggar semula setiap kali.
