Tutorial Operasi Penggantian Kedap Minyak Silinder Lembu BYD 2 tan 3 tan(Rajah1)

Perlindungan keselamatan perlu dilakukan sebelum operasi: letakkan lembu tanah di atas tanah yang rata dan stabil. Bekalan kuasa perlu diputuskan sambungan untuk model elektrik, tekanan hidraulik dalam silinder perlu dilepaskan perlahan-lahan untuk mengelakkan penyemburan minyak hidraulik. Pada masa yang sama, sediakan sepana lengan, pemutar skru, aksesori alat yang disesuaikan dengan pengedap minyak baharu, minyak hidraulik, kain pembersih dan minyak pelincir.

Mula-mula, lakukan pembongkaran silinder: turunkan garpu ke kedudukan paling rendah, keluarkan bolt penyambung silinder dan bingkai, dan keluarkan pemasangan silinder dengan berhati-hati. Gunakan alat khas untuk membuka penutup hujung silinder, mengeluarkan komponen omboh secara perlahan, elakkan menggaru permukaan omboh semasa proses, dan secara serentak mengumpul minyak hidraulik yang mengalir keluar untuk pemprosesan seterusnya.

Seterusnya, bersihkan kedap minyak lama dan semak komponen: keluarkan kedap minyak lama pada omboh, lap dinding dalam silinder dan permukaan omboh dengan kain pembersih, dan keluarkan kekotoran minyak sepenuhnya. Periksa sama ada blok silinder dan omboh haus dan calar. Haus dan lusuh kecil boleh dibaiki dengan pengisaran kertas pasir halus. Jika haus dan lusuh yang teruk, bahagian yang sepadan perlu diganti.

Kemudian pasang pengedap minyak baru: Sapukan lapisan minyak pelincir secara sekata pada permukaan pengedap minyak baru, dan ketuk pengedap minyak dengan rata ke dalam slot kad omboh dengan alat khas atau tukul getah untuk memastikan tiada herotan, tiada calar di tepi, dan memastikan prestasi pengedap mencapai standard.

Selepas itu, lengkapkan pemasangan dan pentauliahan silinder minyak: masukkan omboh yang dipasang dengan pengedap minyak yang lebih baik ke dalam blok silinder dengan perlahan, ketatkan penutup hujung selepas menjajarkan kedudukan, pasang semula pemasangan silinder minyak ke dalam bingkai dan ketatkan bolt penyambung. Tambah minyak hidraulik yang memenuhi spesifikasi untuk membersihkan udara dalam silinder bagi memastikan sistem hidraulik berjalan lancar.

Akhir sekali, uji mesin untuk menyemak: Hidupkan lembu tanah, kendali angkat garpu beberapa kali, perhatikan sama ada silinder bocor minyak dan sama ada lif garpu adalah stabil. Jika berlaku kebocoran minyak atau operasi yang tidak normal, adalah perlu untuk membuka semula dan menyemak status pemasangan meterai minyak atau haus dan lusuh silinder sehingga penyelesaian masalah. Anda perlu sentiasa menyemak keadaan pengedap minyak untuk mengelakkan operasi beban lampau dan memanjangkan hayat bahagian.
