Umhlahlandlela osekelwe esimweni somkhiqizi wokukhethaamaphampu e-hydraulicngomsebenzi wezimboni oqhubekayo — ukuhlukaniswa komjikelezo womthwalo, ukuhlaziywa komsebenzi, kanye nohlaka lwesinqumo olufanisa ubuchwepheshe bephampu nesimo sakho sokusebenza esithile.

Isikhungo sethu sokukhiqiza i-Ningbo sihlinzeke ngamaphampu e-vane ukuze kusetshenziswe imisebenzi eqhubekayo kuzo zonke izimboni zasolwandle, ezempi, kanye nezimboni iminyaka engaphezu kwengu-15. Ngokolwazi lwethu, incazelo "yomsebenzi oqhubekayo" yiphuzu lokuqala esilicacisayo nomthengi ngamunye.

Esikhungweni sethu sokukhiqiza esinemigqa eyi-6, sakha amaphampu e-vane angaphezu kuka-80,000 ngonyaka emigqeni yokukhiqiza eyi-6, futhi izinhlelo zokusebenza eziqhubekayo zibangela isabelo esikhulayo somkhiqizo wethu. Ithimba lethu lobunjiniyela lithuthukise imiklamo yethu yamaphampu ngeminyaka eminingi yempendulo yasensimini evela kumakhasimende asemanzini, ezempi, kanye nezimboni emhlabeni jikelele.

Okushiwo Yisibopho Esiqhubekayo Empeleni

Uma umthengi ecacisa "intela eqhubekayo" ye-iphampu ye-hydraulic, sidinga ukuchaza ukuthi kusho ukuthini lokho ngokwemigomo yobunjiniyela ngaphambi kokuba sincome umkhiqizo. Ngenxa yokuthi igama elithi “continuous” lisetshenziswa ngokunganaki embonini — ngezinye izikhathi lisho ukuthi “kusebenza kakhulu” kunokuba kube incazelo eqondile yobunjiniyela kagesi — ithimba lethu lobunjiniyela lihlala licacisa ukuhlukaniswa kwemisebenzi yethu ye-IEC esigabeni sokucaciswa.

Ngokwezinga le-IEC 60034-1,Umsebenzi we-S1 (oqhubekayo)kusho ukuthi umshini usebenza ngomthwalo olinganiselwe isikhathi esingenamkhawulo kuze kube yilapho kufinyelelwa futhi kugcinwe ukulingana kokushisa. Kumpompo we-hydraulic, lokhu kusho ukusebenza ngokucindezela okulinganiselwe kanye nokugeleza kokushintsha kokukhiqiza okugcwele — amahora angu-8, amahora angu-16, noma kwezinye izinhlelo zokusebenza amahora angu-24 — ngaphandle kokudlula imikhawulo yokushisa yama-bearings, ama-seal, kanye noketshezi. Ngenxa yokuthi ukulingana kokushisa kumpompo we-hydraulic ngokuvamile kudinga imizuzu engama-30 kuya kwengama-60 yokusebenza okuqhubekayo, ipompo esebenza amahora ama-2 ngomthwalo ogcwele bese ivala AKUSIYO umsebenzi oqhubekayo — iwumsebenzi oqhubekayo onesikhathi eside esisebenzayo.

Umphumela osebenzayo wokukhethwa kwephampu ukuthi yonke ingxenye kumele yakhelwe ukukhiqizwa kokushisa okuqhubekayo. Amaphampu ethu e-servo vane e-ABT series aklanyelwe umsebenzi oqhubekayo emishinini yokubumba umjovo, lapho ukusebenza amahora angu-24 ngosuku kuyindinganiso yokukhiqiza. Ama-bearings alinganiswa ngemithwalo eqhubekayo ye-radial kanye ne-axial, ama-vanes agcina ukuvala emazingeni okushisa aphezulu oketshezi (kufika kuma-degree Celsius angu-80 njalo), kanyeindandatho yekhameraUbuso buqinisiwe ukuze buhlale isikhathi eside bugugile. Ngenxa yokuthi iphampu esebenza emsebenzini we-S1 ikhiqiza ukushisa njalo,ichibiUsayizi, umthamo wokupholisa, kanye nokukhethwa kwe-viscosity yoketshezi kumele kubhekele umthwalo wokushisa oqhubekayo — ithimba lethu lobunjiniyela linikeza amaphepha okusebenzela okubala ukushisa azo zonke izinhlelo zokusebenza zomsebenzi oqhubekayo.
