Punca kehilangan paip minyak hidraulik dan pengedap minyak, bahagian aksesori penyelenggaraan trak forklift BYD.(Rajah1)

Sebagai komponen penghantaran kuasa teras forklift elektrik, operasi sistem hidraulik yang stabil secara langsung mempengaruhi kecekapan operasi dan hayat perkhidmatan peralatan. Antaranya, paip minyak hidraulik dan pengedap minyak adalah komponen utama untuk memastikan pengedap sistem hidraulik. Jika berlaku haus dan lusuh semasa penggunaan harian, ia adalah mudah untuk menyebabkan kerosakan seperti kebocoran minyak hidraulik dan kekurangan kuasa, meningkatkan kos operasi dan penyelenggaraan.

Kehilangan paip minyak hidraulik terutamanya disebabkan oleh beberapa faktor. Pertama, ia tertakluk kepada kesan tekanan tinggi untuk masa yang lama, lif yang kerap dan operasi stereng forklift akan menyebabkan paip minyak berulang kali dipengaruhi oleh perubahan tekanan, dan keretakan keletihan secara beransur-ansur berlaku di dinding paip, terutamanya kepekatan tegasan di bahagian sambungan, yang lebih mudah rosak. Kedua, haus dan lusuh luaran, pasir dan benda tajam dalam persekitaran kerja boleh menggaru permukaan paip minyak. Jika tidak dijumpai dalam masa, kerosakan akan beransur-ansur mengembang dan akhirnya menyebabkan kebocoran minyak hidraulik. Ketiga, suhu minyak terlalu tinggi. Operasi sistem hidraulik yang lama dan beban tinggi akan menyebabkan suhu minyak meningkat, mempercepatkan penuaan bahan paip minyak, mengurangkan rintangan tekanannya, dan seterusnya meningkatkan risiko kerosakan.

Kehilangan kedap minyak juga mempunyai pelbagai punca. Yang pertama ialah penuaan semula jadi anggota pengedap itu sendiri. Dengan peningkatan masa penggunaan, bahan getah kedap minyak akan mengeras dan retak akibat pengoksidaan dan persekitaran suhu tinggi, kehilangan keanjalan asalnya dan tidak dapat mengikat komponen dengan ketat, mengakibatkan kegagalan pengedap. Yang kedua ialah pemasangan yang tidak betul. Jika kedudukan pemasangan pengedap minyak diimbangi dan terhimpit berlebihan semasa penyelenggaraan, tekanan pada permukaan pengedap akan tidak sekata, dan kebocoran mungkin berlaku dalam masa yang singkat. Di samping itu, kekotoran dalam minyak hidraulik juga merupakan faktor penting. Selepas kekotoran memasuki permukaan pengedap, ia akan terus haus bibir pengedap minyak, memusnahkan kesan pengedap dan memburukkan lagi kelajuan kehilangan.

Apabila memilih aksesori penyelenggaraan, adalah perlu untuk memberi keutamaan untuk memadankan paip minyak hidraulik dan pengedap minyak dengan spesifikasi yang sesuai untuk memastikan bahan, saiz dan komponen asal adalah konsisten, dan mengelakkan kehilangan seterusnya akibat masalah kesesuaian. Paip minyak harus menggunakan bahan berkualiti tinggi dengan rintangan tekanan tinggi dan rintangan haus, dan pengedap minyak perlu mempunyai rintangan suhu tinggi dan rintangan minyak yang baik untuk menyesuaikan diri dengan persekitaran kerja sistem hidraulik. Dalam penyelenggaraan harian, adalah perlu untuk kerap memeriksa sama ada permukaan paip minyak retak dan kesan kerosakan, sama ada terdapat kelonggaran pada sambungan, dan sama ada terdapat tanda-tanda kebocoran minyak pada bahagian pengedap minyak. Pada masa yang sama, kawal suhu minyak sistem hidraulik secara munasabah, elakkan operasi yang lama dan tinggi, gantikan minyak hidraulik yang rosak tepat pada masanya, kurangkan haus dan lusuh oleh kekotoran pada bahagian pengedap, dan kurangkan kebarangkalian kerugian daripada sumber.

Dengan pemahaman yang mendalam tentang punca kehilangan paip minyak hidraulik dan pengedap minyak, pemilihan aksesori penyelenggaraan yang munasabah dan pengurusan penyelenggaraan harian, kejadian kerosakan sistem hidraulik forklift elektrik dapat dikurangkan dengan berkesan, hayat perkhidmatan keseluruhan peralatan dapat dipanjangkan, dan kestabilan dan keselamatan proses operasi dapat dipertingkatkan.
