Paano suriin ang pagkabigo ng electric forklift?(larawan1)

Ang mga electric forklift ay malawakang ginagamit sa warehousing, logistics at iba pang mga sitwasyon. Ang lifting function ay isa sa mga pangunahing kakayahan nito sa pagpapatakbo. Kapag nagkaroon ng pagkabigo sa pag-angat, ito ay direktang makakaapekto sa kahusayan sa pagpapatakbo at maging sanhi ng mga potensyal na panganib sa kaligtasan. Ang pag-master ng mga pamamaraan ng siyentipikong pagsisiyasat ay maaaring mabilis na mahanap at malutas ang mga problema at matiyak ang matatag na operasyon ng mga forklift.

Suriin ang sistema ng supply ng kuryente

Una sa lahat, kinakailangan upang kumpirmahin kung ang pinagmumulan ng kuryente ay maaaring magbigay ng sapat na enerhiya para sa pagpapatakbo ng pag-aangat. Suriin muna ang katayuan ng baterya upang makita kung sapat na ang natitirang lakas ng baterya. Kung masyadong mababa ang power, magiging limitado ang power output ng electric forklift, na magreresulta sa mahinang pag-angat. Kasabay nito, suriin kung ang mga terminal ng baterya ay maluwag o na-oxidized. Ang mahinang mga kable ay magdudulot ng hindi matatag na supply ng kuryente at makakaapekto sa paghahatid ng kuryente.

Pagkatapos ay suriin ang mga kondisyon ng pagtatrabaho ng motor sa pagmamaneho. Sa panahon ng operasyon, bigyang-pansin kung ang motor ay may abnormal na tunog, at hawakan ang shell ng motor upang maramdaman kung ang temperatura ay masyadong mataas. Kung ang motor ay sobrang init o gumagawa ng abnormal na ingay, maaaring may mga problema tulad ng pinsala sa panloob na paikot-ikot at pagkasira ng bearing, na magreresulta sa hindi sapat na power output, na makakaapekto sa lifting function.

I-troubleshoot ang hydraulic system

Ang hydraulic system ay ang pangunahing actuator ng lifting function ng electric forklift, at karamihan sa mga pagkakamali ay nagmumula dito. Una, suriin ang katayuan ng hydraulic oil upang suriin kung ang antas ng hydraulic oil ay nasa loob ng tinukoy na hanay. Kung ang antas ng likido ay masyadong mababa, ang hydraulic pump ay maa-absorb at ang sapat na presyon ay hindi maitatag. Kasabay nito, obserbahan ang kulay at kalinisan ng hydraulic oil. Kung ang langis ay itim at may mga dumi, nangangahulugan ito na ang langis ay lumala, na makakaapekto sa normal na operasyon ng mga hydraulic component at kailangang mapalitan sa oras.

Pagkatapos ay suriin ang patency ng circuit ng langis, suriin kung ang hydraulic oil pipe ay baluktot o nasira, at kung mayroong anumang pagtagas ng langis sa iba 't ibang mga balbula at joints. Kung ang circuit ng langis ay naharang o tumutulo, ito ay magdudulot ng pagkawala ng haydroliko na presyon at magiging sanhi ng mahinang pag-angat. Bilang karagdagan, maaari mong suriin kung ang elemento ng hydraulic filter ay naharang. Ang pagbara ng elemento ng filter ay hahadlang sa daloy ng langis at mabawasan ang presyon ng system.

Panghuli, suriin ang pag-andar ng hydraulic pump, patakbuhin ang lifting device pagkatapos simulan ang forklift, at damhin kung stable ang running sound ng hydraulic pump. Kung ang hydraulic pump ay may abnormal na ingay o hindi sapat na pressure output, maaaring ang panloob na pagkasira ay malubha at hindi makapagbibigay ng sapat na kapangyarihan para sa lifting system.

Suriin ang mga bahagi ng kontrol at sensor

Ang pagkabigo ng mga bahagi ng kontrol ay maaari ding humantong sa mahinang pag-angat. Suriin muna ang lifting control valve. Kapag pinapatakbo ang lifting handle, obserbahan kung ang balbula ay maaaring buksan at sarado nang normal. Kung ang balbula ay natigil o pagod, ito ay makakaapekto sa direksyon ng daloy at pagsasaayos ng presyon ng hydraulic oil, na nagreresulta sa hindi sapat na lifting power.

Suriin muli ang pressure sensor. Ang sensor ay may pananagutan sa pagsubaybay sa presyon ng hydraulic system. Kung ang sensor ay nabigo at ang pressure signal ay hindi tumpak na maibabalik, ang control system ay hindi makakapag-adjust sa power output, na magreresulta sa mahinang pag-angat. Maaaring gamitin ang mga propesyonal na kagamitan upang makita kung normal ang signal ng sensor at hatulan kung gumagana ito nang normal.

Suriin ang mekanikal na istraktura ng paghahatid

Ang pagkasira ng mga mekanikal na bahagi ay maaari ring makaapekto sa epekto ng pag-aangat. Suriin kung ang lifting chain ay pinahaba, pagod, o nasira. Ang matinding pagkasuot ng chain ay hahantong sa pagbaba sa transmission efficiency at hindi maaaring epektibong magmaneho ng fork para iangat at ibaba. Kasabay nito, suriin kung ang mga pulley, guide rail at iba pang bahagi ay natigil o nasira. Ang mga problema sa mga bahaging ito ay magpapataas ng lifting resistance at magdudulot ng kahinaan. Bilang karagdagan, suriin kung mayroong panloob na pagtagas sa hydraulic cylinder. Ang panloob na pagtagas sa hydraulic cylinder ay magdudulot ng pagkawala ng presyon at makakaapekto sa lifting power.

Ang pag-troubleshoot ng kahinaan sa pag-aangat ng electric forklift ay dapat na isagawa nang sunud-sunod sa pagkakasunud-sunod mula sa madali hanggang sa mahirap, mula sa labas hanggang sa loob, at ang mga posibleng fault point ay dapat na isa-isang alisin. Sa pang-araw-araw na operasyon, ang regular na pagpapanatili ng forklift ay maaaring epektibong mabawasan ang paglitaw ng mga naturang pagkabigo at pahabain ang buhay ng serbisyo ng forklift.
