Bagaimana untuk memilih forklift litium untuk penyimpanan sejuk? Kriteria pemilihan teras untuk keadaan suhu rendah di bawah sifar.

Persekitaran storan sejuk mempunyai keperluan prestasi yang lebih ketat untuk peralatan kerja disebabkan oleh ciri-ciri suhu rendah, kelembapan tinggi dan sebagainya. Dalam konteks perkembangan pesat logistik rantai sejuk, forklift litium-elektrik untuk penyimpanan sejuk secara beransur-ansur menjadi pilihan arus perdana berdasarkan kelebihan perlindungan alam sekitar dan bunyi yang rendah. Tetapi dalam menghadapi keadaan kerja suhu rendah di bawah sifar, cara memilih forklift litium yang sesuai secara saintifik memerlukan pertimbangan menyeluruh daripada pelbagai dimensi teras.

Pertama, kesesuaian suhu rendah sistem bateri adalah salah satu pertimbangan teras. Aktiviti kimia bateri litium pada suhu rendah akan berkurangan, mengakibatkan pengurangan output kapasiti dan penurunan kecekapan pengecasan dan nyahcas. Apabila memilih model, anda perlu memberi perhatian kepada reka bentuk penebat haba pek bateri, seperti penggunaan lapisan penebat pembalut atau sistem pemanasan, untuk memastikan suhu operasi bateri berada dalam julat yang munasabah. Pada masa yang sama, sistem pengurusan bateri (BMS) perlu mempunyai algoritma pampasan dinamik untuk keadaan operasi suhu rendah, memantau keadaan sel dalam masa nyata, mengelakkan cas berlebihan dan nyahcas, dan memastikan kestabilan hayat bateri. Sesetengah peranti juga akan dilengkapi dengan fungsi pra-pemanasan suhu rendah, meningkatkan aktiviti bateri melalui pemanasan awal yang singkat sebelum dimulakan, dan menyesuaikan diri dengan persekitaran suhu rendah yang melampau.

Kedua, kecekapan operasi suhu rendah sistem kuasa secara langsung mempengaruhi kecekapan operasi. Suhu rendah akan menjejaskan output tork permulaan dan kecekapan operasi motor, mengakibatkan kekurangan kuasa atau peningkatan penggunaan tenaga. Apabila memilih model, kebolehsuaian suhu rendah motor harus diperiksa, dan motor domain suhu yang luas harus diutamakan. Reka bentuk boleh menstabilkan output kuasa undian dalam julat -20 ° C hingga 50 ° C untuk mengelakkan pengecilan tork akibat suhu rendah. Pada masa yang sama, sistem penghantaran perlu mengoptimumkan reka bentuk, seperti mengguna pakai komponen penghantaran dengan pekali geseran rendah, mengurangkan kehilangan mekanikal pada suhu rendah, dan memastikan penghantaran kuasa yang lancar. Di samping itu, memadankan peranti kerja yang sesuai, seperti gantri, garpu, dan lain-lain, perlu mengambil kira kekuatan struktur dalam persekitaran suhu rendah untuk mengelakkan kerapuhan suhu rendah daripada menjejaskan kestabilan operasi.

Kebolehpercayaan suhu rendah sistem kawalan juga tidak boleh diabaikan. Persekitaran suhu rendah mengemukakan keperluan yang lebih tinggi untuk kestabilan komponen elektrik. Sistem kawalan perlu menggunakan komponen elektronik tahan suhu rendah, dan antara muka litar tertutup diperlukan untuk mengelakkan pencerobohan air pemeluwapan dan menyebabkan litar pintas. Sistem kawalan elektrik sesetengah peranti mempunyai fungsi diagnosis diri kerosakan untuk mengenal pasti keabnormalan penderia dengan cepat pada suhu rendah dan mengelakkan salah perhitungan yang menjejaskan keselamatan operasi. Di samping itu, komponen interaksi manusia-komputer seperti pemegang operasi, papan pemuka dan lain-lain perlu mempunyai pengoptimuman maklum balas sentuhan dalam persekitaran suhu rendah untuk memastikan kawalan tepat semasa mengendalikan sarung tangan.

Struktur badan dan reka bentuk perlindungan alam sekitar juga perlu diberi perhatian. Persekitaran suhu rendah di dalam storan sejuk dengan mudah boleh menyebabkan pembekuan pada permukaan peralatan dan menjejaskan operasi normal peralatan. Reka bentuk badan harus mempertimbangkan pemeliharaan haba dan anti pemeluwapan, contohnya, silo bateri mempunyai struktur pengedap, teksi dilengkapi dengan kaca kalis sejuk untuk mengurangkan penghantaran kapasiti sejuk. Pilihan tayar perlu mengambil kira cengkaman suhu rendah untuk mengelakkan gelinciran di atas tanah yang licin, dan sesetengah model juga akan dilengkapi dengan rantai anti-gelincir atau reka bentuk corak bunga khas. Di samping itu, peralatan perlu lulus ujian persekitaran suhu rendah secara keseluruhan untuk memastikan semua komponen masih boleh berfungsi bersama dalam keadaan yang melampau seperti tolak 30 ° C untuk memanjangkan hayat perkhidmatan peralatan.

Akhir sekali, pertimbangan menyeluruh tentang sistem keselamatan dan operasi dan penyelenggaraan adalah penting. Di bawah keadaan suhu rendah, perlindungan keselamatan peralatan adalah amat penting dan fungsi perlindungan anti-beku diperlukan. Sebagai contoh, sistem hidraulik akan berhenti beroperasi secara automatik pada suhu rendah untuk mengelakkan kerosakan peralatan akibat pemejalan minyak. Untuk operasi dan penyelenggaraan harian, model yang mudah diselenggara harus dipilih, seperti bateri boleh ditanggalkan dengan cepat dan dicas, komponen utama dilengkapi dengan tetingkap pemeriksaan visual, supaya pengendali dapat menyelesaikan masalah dengan cepat dalam persekitaran suhu rendah. Pada masa yang sama, peralatan perlu mematuhi spesifikasi keselamatan operasi suhu rendah dan mengelakkan kemalangan keselamatan akibat kegagalan peralatan.

Kesimpulannya, pemilihan forklift litium untuk penyimpanan sejuk di bawah keadaan suhu rendah perlu menyepadukan elemen teras seperti prestasi bateri, sistem kuasa, sistem kawalan, perlindungan badan dan operasi dan penyelenggaraan yang selamat, digabungkan dengan julat suhu dalam senario operasi sebenar, berat barang, kecekapan pusing ganti dan parameter lain, pilih peralatan yang lebih sesuai untuk memastikan kecekapan dan keselamatan operasi penyimpanan sejuk.
