Penghalang elemen penapis hidraulik forklift menyebabkan lif lemah, dan proses penggantian aksesori akan dikongsi.(Rajah1)

Dalam operasi harian forklift elektrik, lif yang lemah adalah manifestasi kegagalan yang lebih biasa. Ramai pengendali sering tidak dapat memulakan apabila mereka menghadapi masalah sedemikian. Malah, banyak kali penyebabnya ialah penyumbatan elemen penapis hidraulik. Sistem hidraulik ialah sumber kuasa teras untuk fungsi mengangkat forklift elektrik. Elemen penapis hidraulik memainkan peranan penting dalam menapis kekotoran dalam cecair minyak dan memastikan kebersihan cecair. Apabila elemen penapis disekat, ia akan terus menjejaskan operasi normal sistem hidraulik.

Prinsip penyumbatan kartrij penapis hidraulik untuk menyebabkan lif lemah tidak rumit. Tindakan mengangkat forklift elektrik bergantung pada pam hidraulik untuk menghantar minyak tekanan tinggi untuk menolak silinder, dan kartrij penapis hidraulik bertanggungjawab untuk memintas serpihan logam, habuk, glia dan kekotoran lain dalam cecair minyak. Apabila kartrij penapis digunakan terlalu lama, atau terdapat banyak kekotoran dalam persekitaran kerja, lubang penapis kartrij penapis akan disekat secara beransur-ansur, mengakibatkan peningkatan rintangan aliran minyak, pam hidraulik tidak dapat memberikan tekanan yang mencukupi untuk silinder minyak, dan akhirnya kenaikan adalah perlahan atau bahkan mustahil. Di samping itu, penyumbatan jangka panjang juga boleh memburukkan haus komponen seperti pam hidraulik dan silinder minyak, mengakibatkan kerosakan yang lebih serius.

Sebelum menggantikan kartrij penapis hidraulik, anda perlu membuat persediaan dengan baik. Pertama, letakkan trak forklift elektrik di kawasan yang rata dan mempunyai pengudaraan yang baik, tarik brek tangan dan matikan bekalan kuasa untuk memastikan keselamatan kerja; kedua, sediakan alat dan aksesori yang sesuai seperti kartrij penapis hidraulik baharu, sepana, bekas penerima minyak, kain pembersih, dan lain-lain, perhatikan bahawa model kartrij penapis baharu harus sepadan dengan sistem hidraulik forklift, untuk mengelakkan pengedap yang buruk atau kesan penapisan yang buruk akibat model yang tidak konsisten; akhirnya, rujuk manual operasi trak forklift terlebih dahulu untuk memahami lokasi pemasangan khusus kartrij penapis hidraulik, supaya anda boleh mempunyai nombor dalam fikiran.

Proses penggantian khusus boleh dibahagikan kepada langkah-langkah berikut: Langkah pertama, nyahcas minyak hidraulik lama. Cari port nyahcas minyak tangki hidraulik, letakkan bekas minyak di bawah, perlahan-lahan buka injap nyahcas minyak, tutup injap selepas minyak lama dilepaskan sepenuhnya, beri perhatian kepada minyak lama yang dikumpul untuk dikendalikan dengan betul untuk mengelakkan pencemaran alam sekitar. Langkah kedua ialah mengeluarkan elemen penapis lama dengan berhati-hati. Gunakan sepana untuk mengelakkan kekotoran dalam elemen penapis daripada jatuh ke dalam litar minyak hidraulik semasa proses. Selepas dibuka, anda boleh memerhatikan tahap pencemaran pada permukaan elemen penapis dan seterusnya mengenal pasti punca kerosakan. Langkah ketiga ialah membersihkan tempat duduk pemasangan. Lap permukaan sentuhan tempat duduk dengan kain lap pembersih untuk memeriksa sama ada gasket rosak atau penuaan. Jika terdapat masalah, anda perlu menggantikan pengedap baru tepat pada masanya untuk mengelakkan kebocoran minyak pada masa hadapan. Langkah keempat ialah memasang elemen penapis baharu. Sapukan sedikit minyak hidraulik yang bersih pada cincin pengedap elemen penapis baharu, kemudian skru elemen penapis ke tempat duduk pelekap dengan tangan anda. Selepas gelang pengedap dipasang, ketatkan perlahan dengan sepana, berhati-hati agar tidak menggunakan kekerasan yang berlebihan untuk mengelakkan kerosakan pada elemen penapis atau tempat duduk pemasangan. Langkah kelima, tambah minyak hidraulik baharu. Tambahkan minyak hidraulik yang sesuai ke dalam tangki minyak hidraulik mengikut piawaian paras minyak yang ditetapkan dalam manual forklift, dan elakkan campuran minyak ke dalam kekotoran semasa proses penambahan. Langkah 6, uji fungsi pengangkat. Hidupkan forklift, kerap mengendalikan pemegang pengangkat, dan perhatikan sama ada tindakan pengangkat kembali normal, dan semak sama ada terdapat kebocoran minyak dalam sistem hidraulik untuk memastikan operasi sistem yang stabil selepas penggantian.

Sebagai tambahan kepada penggantian selepas kegagalan, penyelenggaraan harian juga penting. Adalah disyorkan untuk menggantikan elemen penapis hidraulik dengan kerap mengikut kitaran penyelenggaraan forklift. Biasanya, ia boleh diganti sekali setiap 500 jam bekerja; habuk dan serpihan pada permukaan forklift perlu dibersihkan tepat pada masanya selepas operasi harian untuk mengurangkan kebarangkalian kekotoran memasuki sistem hidraulik; kerap menyemak warna dan keadaan minyak hidraulik. Jika minyak didapati keruh dan hitam, ia perlu diganti tepat pada masanya untuk mengurangkan risiko penyumbatan elemen penapis pada sumbernya.
