Langkah penggantian minyak hidraulik anti haus lembu tanah manual dan pemilihan minyak.(Rajah1)

Lembu tanah manual ialah peralatan pengendalian jarak dekat yang biasa digunakan. Operasi sistem hidraulik yang stabil adalah teras kerjanya yang cekap, manakala pemilihan rasional dan penggantian tetap minyak hidraulik anti haus secara langsung mempengaruhi hayat perkhidmatan dan status operasi peralatan.

Dalam pemilihan minyak hidraulik anti haus, beberapa penunjuk teras perlu diberi perhatian. Pertama, gred kelikatan harus digabungkan dengan pemilihan suhu ambien. Produk minyak dengan kelikatan sederhana boleh dipilih dalam persekitaran suhu bilik, dan jenis dengan kecairan yang lebih baik dalam suhu rendah perlu dipilih dalam persekitaran suhu rendah untuk memastikan sistem hidraulik dapat bertindak balas dengan lancar pada suhu yang berbeza. Kedua ialah prestasi anti haus. Minyak hidraulik anti haus yang layak boleh membentuk filem pelindung seragam pada permukaan komponen hidraulik, mengurangkan haus langsung antara logam dan mengurangkan kebarangkalian kerosakan. Di samping itu, sifat anti-karat dan anti-karat produk minyak harus dipertimbangkan untuk mengelakkan karat dalam sistem hidraulik dan menjejaskan ketepatan operasi.

Menggantikan minyak hidraulik anti haus perlu mengikut langkah standard untuk memastikan penggantian yang teliti. Langkah pertama ialah menyediakan minyak hidraulik anti haus yang sesuai, bekas minyak, sepana, kain pembersih dan alat lain. Letakkan lembu tanah secara manual di atas tanah yang rata, tutup injap hidraulik untuk mengelakkan penyemburan minyak hidraulik semasa operasi. Langkah kedua ialah mengosongkan minyak lama, mencari port nyahcas minyak tangki hidraulik, membuka injap nyahcas minyak selepas meletakkan bekas penerima minyak, dan mengetatkan injap nyahcas minyak selepas minyak lama dikosongkan sepenuhnya. Langkah ketiga ialah membersihkan sistem, sejumlah kecil minyak hidraulik baharu boleh disuntik, pemegang lif lembu tanah boleh dimanipulasi berulang kali, supaya minyak baharu boleh dikosongkan semula selepas membilas saluran paip dalaman untuk mengeluarkan sisa minyak dan kekotoran lama. Langkah keempat ialah menambah minyak baharu, membuka penutup tangki, menyuntik minyak hidraulik anti haus yang memenuhi spesifikasi secara perlahan, dan berhati-hati agar tidak melebihi paras cecair tertinggi tangki. Langkah kelima ialah ekzos dan pemeriksaan, memanipulasi pemegang lif untuk mengeluarkan udara dari sistem beberapa kali, kemudian menyemak paras cecair tangki dan menambahnya ke lokasi yang sesuai, dan akhirnya mengesahkan bahawa tiada kebocoran pada setiap antara muka. Uji sama ada lif lembu lancar.

Penggantian tetap minyak hidraulik anti haus yang layak adalah pautan utama dalam penyelenggaraan harian lembu tanah manual. Pemilihan dan operasi yang betul boleh memanjangkan kitaran hayat peralatan dengan berkesan, mengurangkan kos penyelenggaraan dan memastikan pengendalian yang cekap.
