Bagaimana untuk menangani tekanan pam minyak hidraulik yang tidak mencukupi? Cadangan penggantian serentak saluran paip kartrij penapis dicadangkan.(Rajah1)

Pam minyak hidraulik ialah komponen teras sistem hidraulik forklift elektrik. Apabila masalah tekanan tidak mencukupi berlaku, ia secara langsung akan menyebabkan pergerakan forklift seperti angkat, kecondongan dan lain-lain menjadi lambat atau bahkan gagal, menjejaskan kecekapan dan keselamatan operasi. Apabila menghadapi kegagalan sedemikian, anda perlu menyemak dan menanganinya mengikut langkah. Pada masa yang sama, anda juga perlu memberi perhatian kepada penggantian serentak elemen penapis dan saluran paip untuk menyelesaikan masalah dari punca utama.

Pertama, pemeriksaan asas sistem hidraulik diperlukan. Mula-mula, periksa paras cecair dan kualiti minyak hidraulik. Jika paras cecair lebih rendah daripada nilai standard, tambah minyak hidraulik yang memenuhi spesifikasi tepat pada masanya; jika minyak keruh, hitam atau mengandungi kekotoran, bermakna minyak telah rosak, semua perlu diganti. Kemudian, semak sama ada terdapat titik kebocoran dalam sistem, fokus pada pemeriksaan bahagian seperti pengedap pam minyak, sambungan paip, pengedap silinder hidraulik, dan lain-lain. Jika kebocoran didapati, gantikan elemen pengedap yang rosak tepat pada masanya dan pasangkan penyambung.

Apabila masalah minyak dan kebocoran dihapuskan, fokus pada keadaan kartrij dan saluran paip. Penggunaan jangka panjang kartrij penapis hidraulik akan menimbun sejumlah besar kekotoran, yang akan menghalang peredaran minyak selepas penyumbatan, mengakibatkan penurunan tekanan keluaran pam minyak; dan saluran paip yang sudah tua mungkin mengalami kakisan, ubah bentuk atau sekatan separa pada dinding dalaman, yang juga akan menjejaskan penghantaran tekanan. Pada masa ini, hanya menggantikan kartrij penapis atau hanya menggantikan saluran paip tidak dapat menyelesaikan masalah sepenuhnya - kekotoran saluran paip yang tinggal akan menyekat kartrij penapis baru sekali lagi, dan penyumbatan kartrij penapis lama juga boleh mencemarkan saluran paip baru dan membentuk lingkaran ganas.

Oleh itu, adalah disyorkan untuk menggantikan kartrij penapis dan saluran paip pada masa yang sama. Sebelum penggantian, berhenti dan lepaskan tekanan sistem hidraulik untuk mengelakkan bahaya letupan minyak. Apabila menggantikan, keluarkan kartrij penapis lama dan saluran paip penuaan untuk membersihkan antara muka pam minyak dan kekotoran di sekelilingnya; apabila memasang saluran paip baharu, pastikan sambungan ketat untuk mengelakkan kebocoran; apabila memasang kartrij penapis baharu, beri perhatian untuk meletakkannya dengan betul mengikut arah pengenalan untuk mengelakkan kesan buruk pemasangan penapis. Selepas penggantian selesai, mulakan forklift untuk ujian tanpa beban. Perhatikan sama ada tindakan mengangkat dan condong lancar. Pada masa yang sama, tekanan keluaran pam minyak dikesan dengan bantuan tolok tekanan untuk mengesahkan bahawa tekanan kembali ke julat standard.

Dalam penyelenggaraan harian, keadaan elemen penapis dan saluran paip juga perlu diperiksa dengan kerap, kitaran penggantian dirumuskan mengikut persekitaran kerja dan kekerapan penggunaan, tekanan pam minyak hidraulik yang tidak mencukupi dikurangkan daripada sumbernya, dan hayat perkhidmatan peralatan dilanjutkan.
