Forklift steering cylinder oil seal penuaan dan kebocoran, set lengkap kit perbaikan Petunjuk penggunaan(tokoh1)

Silinder kemudi forklift listrik adalah komponen inti untuk memastikan kemudi kendaraan yang fleksibel. Sebagai komponen penyegel kunci silinder, segel oli rentan terhadap penuaan dan kebocoran karena erosi oli hidrolik jangka panjang, gesekan mekanis, dan faktor lingkungan. Jika tidak ditangani tepat waktu, itu tidak hanya akan meningkatkan hilangnya oli hidrolik, tetapi juga menyebabkan peningkatan ketahanan kemudi dan penurunan akurasi, yang akan mempengaruhi operasi normal dan bahkan keselamatan operasi forklift.

Sebelum memulai perbaikan, perlu ditentukan secara akurat penuaan dan kebocoran segel oli. Selama inspeksi harian, perhatikan apakah ada akumulasi film oli terus menerus di permukaan batang piston silinder, apakah ada noda oli pada rangka dan tanah di sekitar silinder, dan rasakan perubahan gaya kemudi forklift. Jika kemudi jelas berat, kemungkinan besar kegagalan segel oli akan menyebabkan kebocoran oli hidrolik dan tekanan yang tidak mencukupi.

Sebelum menggunakan set lengkap kit perbaikan, lakukan persiapan. Pertama-tama parkir forklift di tempat yang datar dan stabil, tarik rem tangan dan potong catu daya, dan selesaikan pelepas tekanan dengan melepaskan katup pelepas tekanan dari sistem hidrolik untuk menghindari pelepasan oli hidrolik selama proses pembongkaran. Siapkan kit perbaikan (termasuk cincin debu yang sesuai, segel oli utama, segel tambahan, dll.) dan alat khusus, seperti kunci pas soket, obeng heksagonal, alat pembongkaran silinder hidrolik, kain pembersih, dll.

Selama operasi resmi, langkah pertama adalah membongkar silinder. Dukung bagian depan forklift dengan dongkrak, buat roda kemudi ditangguhkan, lepaskan sambungan antara kedua ujung silinder dan mekanisme kemudi dan pipa hidrolik, dan lepaskan silinder dengan lancar. Langkah kedua adalah membongkar silinder: Buka tutup ujung silinder, tarik perlahan keluar batang piston, dan gunakan kain pembersih untuk menyeka noda oli dan memakai puing-puing di dinding bagian dalam silinder dan permukaan batang piston. Perhatikan untuk menghindari goresan permukaan presisi. Langkah ketiga adalah mengganti segel: Sesuai dengan instruksi komponen dalam kit perbaikan, pasang cincin debu baru, segel oli utama, dan segel tambahan secara berurutan. Perhatikan arah segel saat memasang, dan gunakan alat khusus untuk membantu mendorong untuk menghindari distorsi dan kerusakan segel. Langkah 4 Pasang silinder: Muat perlahan batang piston dengan sedikit oli hidrolik ke dalam silinder, kencangkan penutup ujung dan pastikan pengetatan seragam untuk mencegah gaya yang tidak rata pada bagian penyegelan. Langkah 5 Pasang kembali forklift: Sambungkan kembali silinder ke mekanisme kemudi dan saluran hidrolik, dan periksa kekencangan semua sambungan.

Setelah pemasangan selesai, proses pengujian perlu dilakukan. Mulai forklift, operasikan mekanisme kemudi berkali-kali, amati apakah ada tanda-tanda kebocoran di bagian silinder, dan rasakan apakah gaya kemudi kembali normal. Tes mengemudi tanpa beban dan beban ringan selanjutnya dapat dilakukan untuk memastikan bahwa kemudi fleksibel dan bebas dari kartu, dan kinerja penyegelan stabil. Selama operasi, perlu dicatat bahwa semua segel harus ditangani dengan hati-hati untuk menghindari goresan oleh benda tajam. Tindakan selama pembongkaran dan perakitan harus lancar untuk mencegah kerusakan pada bagian presisi silinder.
