Desain anti-pembekuan forklift penyimpanan dingin BYD: harness kabel dan detail adaptasi sistem hidrolik(tokoh1)

Tantangan inti dari forklift penyimpanan dingin di lingkungan bersuhu rendah

Lingkungan operasi penyimpanan dingin telah berada dalam kisaran minus 10 derajat Celcius hingga minus 40 derajat Celcius untuk waktu yang lama, disertai dengan kelembaban tinggi dan pembentukan es yang mudah. Ketika forklift biasa beroperasi di lingkungan seperti itu, mereka rentan terhadap masalah fraktur rapuh harness kawat dan kegagalan kartu sistem hidrolik, yang secara langsung mempengaruhi efisiensi operasi dan masa pakai peralatan. Oleh karena itu, desain antibeku yang ditargetkan adalah salah satu indikator kinerja inti dari forklift penyimpanan dingin.

Optimasi bahan dan struktur pemanfaatan

Lapisan insulasi harness kabel dari forklift penyimpanan dingin terbuat dari bahan poliolefin modifikasi suhu rendah, yang dapat menjaga fleksibilitas di lingkungan minus 40 derajat Celcius, dan tidak akan retak dan jatuh karena embrittlement suhu rendah. Inti kawat mengadopsi struktur untai tembaga lunak multi-untai, yang dapat mempertahankan konduktivitas listrik yang stabil di bawah kondisi pembengkokan, ekspansi termal dan kontraksi yang sering, dan menghindari kegagalan seperti sirkuit terbuka dan kontak yang buruk.

Perlindungan memanfaatkan dan optimasi tata letak

Semua antarmuka harness kabel sepenuhnya disegel dengan celemek penyegelan tahan suhu rendah, yang dapat mengisolasi kelembaban dan embun beku di penyimpanan dingin dan menghindari korsleting yang disebabkan oleh kondensasi yang memasuki antarmuka. Saat tata letak kabel, hindari area rawan embun beku dan tren dingin di penyimpanan dingin sebanyak mungkin, dan simpan 10% hingga 15% dari tunjangan panjang garis untuk mengimbangi tegangan tarik yang disebabkan oleh penyusutan material di lingkungan suhu rendah dan mengurangi risiko harness kawat rusak.

Adaptasi media dan pipa hidrolik

Sistem hidrolik sudah terpasang sebelumnya dengan oli hidrolik anti-aus titik beku rendah saat meninggalkan pabrik. Titik tuang bisa serendah minus 45 derajat Celcius, yang masih dapat mempertahankan fluiditas yang baik di lingkungan suhu rendah dan tidak akan memadat atau macet. Pipa hidrolik terbuat dari low-temperature-resistant karet nitril, yang dapat beradaptasi dengan deformasi yang disebabkan oleh perubahan suhu. Gasket penyegelan low-temperature-resistant ditambahkan pada antarmuka pipa untuk menghindari kebocoran oli hidrolik.

Desain optimal dari sirkuit hidrolik

Sistem hidrolik menambahkan sirkuit pelepas tekanan otomatis untuk shutdown. Setelah peralatan dimatikan, tekanan sisa dalam pipa dapat dilepaskan secara otomatis untuk menghindari sisa oli hidrolik dalam pipa mengembang dan retak karena suhu rendah. Pada saat yang sama, lapisan pelindung insulasi termal ditambahkan ke grup katup hidrolik untuk mengurangi kemungkinan penyumbatan embun beku grup katup dan meningkatkan kecepatan respons operasi hidrolik di lingkungan suhu rendah.

Dalam proses operasi dan pemeliharaan yang sebenarnya, pengguna juga dapat secara teratur memeriksa status lapisan insulasi harness kabel dan mengganti oli hidrolik yang sesuai sesuai dengan kisaran suhu sebenarnya dari penyimpanan dingin, yang selanjutnya memperpanjang masa pakai forklift penyimpanan dingin.
