Paghawak ng mga madalas itanong tungkol sa mga cold storage forklift: Pagbabahagi ng mga ideya para sa pag-troubleshoot ng mga modelo ng BYD(larawan1)

Mga karaniwang abnormal na uri ng forklift sa cold storage environment

Abnormal na output ng kuryente

Ang malamig na imbakan ay nasa isang mababang temperatura at mataas na kahalumigmigan na kapaligiran sa loob ng mahabang panahon. Ang pinakakaraniwang mga abnormalidad ng kuryente sa mga forklift ay kinabibilangan ng tatlong uri: pagkabigo sa pagsisimula, hindi sapat na kapangyarihan, at biglaang pagbaba ng buhay ng baterya. Karamihan sa mga problemang ito ay nauugnay sa epekto ng mababang temperatura sa power battery, at ang ilan sa mga ito ay maaari ding sanhi ng mahinang contact na dulot ng condensed water sa line interface. Sa panahon ng operasyon at pagpapanatili, ang katayuan ng baterya at koneksyon sa linya maaaring suriin muna.

Abnormal na mekanismo ng paglalakad

Ang mga abnormalidad sa paglalakad ay pangunahing makikita bilang mga walking card, hindi maayos na pagpipiloto, at insensitive na preno. Sa mababang temperatura na kapaligiran, ang lubricating grease ng forklift walking parts ay madaling mag-coagulate, na nakakaapekto sa transmission efficiency. Kasabay nito, ang condensed water ay dumidikit sa mga bahagi ng preno at nagyeyelo, na maaari ring humantong sa pagbaba sa sensitivity ng preno. Sa araw-araw na inspeksyon, dapat bigyan ng pansin ang pagpapadulas at pag-deicing ng mga bahagi ng paglalakad..

Abnormal ang control system

Kasama sa mga abnormalidad sa paghawak ang pagkabigo ng button, hindi tumutugon na display screen, at naantalang mga tagubilin sa pagpapatakbo. Karamihan sa mga problemang ito ay sanhi ng pagpasok ng condensed water sa control panel, na nagreresulta sa short circuit o mahinang contact. Sa ilang mga kaso, maaari rin itong sanhi ng pagbaba ng sensitivity ng mga electronic component na dulot ng mababang temperatura. Kapag nag-iimbestiga, ang panel ay dapat na tuyo bago suriin ang panloob na circuit.

Standardized na mga ideya sa pag-troubleshoot

Pre-basic na pagsisiyasat

Pagkatapos makatagpo ng fault, ilipat muna ang forklift sa normal na temperature transition area, at hayaan itong tumayo ng higit sa 30 minuto hanggang sa natural na sumingaw ang condensed water sa ibabaw. Huwag itong i-disassemble at suriin nang direkta sa cold storage, upang maiwasan ang mas maraming condensed water na tumagos sa mga bahagi dahil sa malaking pagkakaiba ng temperatura. Kasabay nito, kinakailangang kumpirmahin kung tama ang power status at operation mode ng forklift, at alisin ang abnormalidad na dulot ng error sa operasyon ng tao.

Naka-target na pagtuklas ng mga sub-module

Pagkatapos alisin ang mga pangunahing problema, suriin ang mga ito nang paisa-isa sa pagkakasunud-sunod ng sistema ng kuryente, mekanismo ng paglalakad, at sistema ng kontrol. Ang power system ay nagbibigay ng priyoridad sa pag-detect ng boltahe ng baterya at katayuan ng koneksyon sa interface. Ang mekanismo ng paglalakad ay nakatuon sa pag-detect ng lubrication ng mga bahagi ng transmission at kung ang mga bahagi ng preno ay nagyelo. Ang control system ay nagbibigay ng priyoridad sa pag-detect ng airtightness ng panel at kung mayroong short circuit sa panloob na circuit. Ang proseso ng pagsisiyasat ay dapat na maitala upang maiwasan ang mga nawawalang abnormal na punto..

Pag-verify at proteksyon ng kasalanan

Pagkatapos ayusin ang fault, huwag agad itong ilagay sa cold storage operation. Subukan muna ito nang walang load sa normal na temperature area nang higit sa 15 minuto, at pagkatapos ay unti-unting pumasok sa low temperature area para gumana pagkatapos makumpirma na ang lahat ng function ay normal. Sa follow-up, ang espesyal na pagpapanatili ay dapat gawin para sa mga forklift na ginagamit sa cold storage nang regular, kabilang ang pagpapalit ng lubricating grease na angkop para sa mababang temperatura, waterproof sealing ng line interface, at regular na pagsubok sa aktibidad ng baterya upang mabawasan ang posibilidad ng pagkabigo.
