Sa pang-araw-araw na operasyon ng mga electric forklift, ang mahinang pag-aangat ay isang medyo pangkaraniwang pagkakamali. Maraming mga operator ang kadalasang walang paraan upang magsimula kapag nakakaranas ng mga ganitong problema. Sa katunayan, ang salarin ay ang pagbara ng hydraulic filter. Bilang pangunahing pinagmumulan ng kuryente para sa pag-angat ng function ng electric forklift, ang hydraulic filter ay gumaganap ng isang mahalagang papel sa pag-filter ng mga impurities sa langis at pagtiyak ng kalinisan ng langis. Kapag ang filter ay na-block, ito ay direktang makakaapekto sa normal na operasyon ng hydraulic system.

Ang prinsipyo ng kahinaan sa pag-aangat na dulot ng pagbara ng elemento ng hydraulic filter ay hindi kumplikado. Ang pagkilos ng pag-aangat ng electric forklift ay umaasa sa hydraulic pump upang maghatid ng mataas na presyon ng langis upang itulak ang silindro, at ang hydraulic filter ay may pananagutan sa pagharang ng mga dumi tulad ng mga labi ng metal, alikabok, at colloid sa langis. Kapag ang elemento ng filter ay ginamit nang masyadong mahaba o mayroong maraming mga dumi sa kapaligiran ng pagtatrabaho, ang butas ng filter ng elemento ng filter ay unti-unting mababara, na magreresulta sa pagtaas ng resistensya ng daloy ng langis, at ang hydraulic pump ay hindi makakapagbigay ng sapat na presyon para sa silindro, at sa kalaunan ay magaganap ang mabagal na pag-aangat o kahit na imposibleng pag-angat. sitwasyon. Bilang karagdagan, ang pangmatagalang pagbara ay maaari ring magpalala sa pagkasira ng mga hydraulic pump, mga silindro ng langis at iba pang mga bahagi, na nagdudulot ng mas malubhang pagkabigo.

Bago palitan ang elemento ng hydraulic filter, kailangan mong gumawa ng sapat na paghahanda. Una, iparada ang electric forklift sa isang patag at well-ventilated na lugar, hilahin pataas ang handbrake at patayin ang kuryente upang matiyak ang ligtas na operasyon; pangalawa, maghanda ng mga bagong hydraulic filter, wrenches, oil receiving container, cleaning wipes at iba pang mga tool at accessories. Tandaan na ang modelo ng bagong elemento ng filter ay dapat tumugma sa hydraulic system ng forklift upang maiwasan ang mahinang sealing o mahinang epekto ng pag-filter dahil sa hindi pantay na mga modelo. Panghuli, suriin ang manual ng pagpapatakbo ng forklift nang maaga upang maunawaan ang partikular na lokasyon ng pag-install ng hydraulic elemento ng filter.

Ang partikular na proseso ng pagpapalit ay maaaring nahahati sa mga sumusunod na hakbang: Ang unang hakbang ay ang paglabas ng lumang hydraulic oil. Hanapin ang oil drain port ng hydraulic oil tank, ilagay ang oil receiving container sa ibaba, dahan-dahang buksan ang oil drain valve, at isara ang valve pagkatapos na ganap na ma-discharge ang lumang langis. Bigyang-pansin ang wastong pagtatapon ng nakolektang lumang langis upang maiwasan ang pagdumi sa kapaligiran. Ang ikalawang hakbang ay i-disassemble ang lumang elemento ng filter. Gumamit ng wrench upang maingat na tanggalin ang lumang elemento ng filter. Sa panahon ng proseso, ang mga dumi sa elemento ng filter ay dapat na pigilan na mahulog sa hydraulic oil circuit. Pagkatapos ng disassembly, ang antas ng polusyon sa ibabaw ng elemento ng filter ay maaaring obserbahan upang higit pang kumpirmahin ang sanhi ng pagkabigo. Ang ikatlong hakbang ay linisin ang installation seat. Punasan ang contact surface ng installation seat ng filter element gamit ang malinis na basahan upang suriin kung nasira o luma na ang sealing gasket. Kung may anumang problema, palitan ang bagong seal sa oras upang maiwasan ang kasunod na pagtagas ng langis. Ang ikaapat na hakbang ay ang pag-install ng bagong elemento ng filter. Maglagay ng kaunting malinis na hydraulic oil sa sealing ring ng bagong elemento ng filter, at pagkatapos ay i-screw ang elemento ng filter sa installation seat sa pamamagitan ng kamay. Pagkatapos magkasya ang sealing ring, dahan-dahang higpitan ito ng wrench. Mag-ingat na huwag gumamit ng labis na puwersa upang maiwasan pinsala sa elemento ng filter o sa upuan ng pag-install. Ang ikalimang hakbang ay magdagdag ng bagong hydraulic oil. Ayon sa pamantayan ng antas ng langis na itinakda sa manwal ng forklift, idagdag ang katugmang hydraulic oil sa hydraulic oil tank, at iwasan ang paghahalo ng langis sa mga dumi sa panahon ng proseso ng pagdaragdag. Ang ikaanim na hakbang ay subukan ang lifting function. Simulan ang forklift, paandarin ang lifting handle nang paulit-ulit, obserbahan kung bumalik sa normal ang pagkilos ng pag-aangat, at suriin kung mayroong anumang pagtagas ng langis sa hydraulic system upang matiyak ang matatag na operasyon ng pinalitan na sistema.

Bilang karagdagan sa pagpapalit pagkatapos ng pagkabigo, ang pang-araw-araw na pagpapanatili ay mahalaga din. Inirerekomenda na regular na palitan ang elemento ng hydraulic filter ayon sa ikot ng pagpapanatili ng forklift. Sa pangkalahatan, maaari itong palitan tuwing 500 oras o higit pa; pagkatapos ng pang-araw-araw na operasyon, ang alikabok at mga labi sa ibabaw ng forklift ay dapat linisin sa oras upang mabawasan ang posibilidad ng mga dumi na pumapasok sa hydraulic system; Regular na suriin ang kulay at estado ng hydraulic oil. Kung ang langis ay nakitang maulap o itim, kailangan itong palitan sa oras upang mabawasan ang panganib ng pagbara ng elemento ng filter mula sa pinagmulan.
