Forklift lifting cylinder oil seepage repair, oil seal at pipeline replacement praktikal na tutorial(larawan1)

Ang pagtagas ng langis mula sa lifting cylinder ng electric forklift ay isang medyo pangkaraniwang pagkakamali sa pang-araw-araw na paggamit. Hindi lamang nito mababawasan ang kahusayan sa pagtatrabaho ng hydraulic system at makakaapekto sa lifting performance ng forklift, ngunit maaari ring magdulot ng mga panganib sa kaligtasan dahil sa akumulasyon ng langis polusyon, na kailangang ayusin sa oras. Ang mga sumusunod ay ang kumpletong praktikal na mga hakbang para sa pagpapalit ng oil seal at pipeline, at ang buong paghahanda ay dapat gawin bago ang pagpapanatili:

Ang una ay ang mga paghahanda sa pagpapanatili. Iparada ang forklift sa isang patag at solidong lupa, hilahin pataas ang parking brake at idiskonekta ang power supply upang palabasin ang pressure sa hydraulic system at maiwasan ang pag-spray ng hydraulic oil sa panahon ng proseso ng disassembly. Maghanda ng mga angkop na tool sa pagpapanatili, kabilang ang sleeve wrench, hexagon wrench, hydraulic cleaner, bagong oil seal, pipeline at gasket na may mga detalye.

Mga hakbang sa pagpapalit ng oil seal: Ang unang hakbang ay i-disassemble ang oil cylinder. Alisin muna ang mga fixing bolts na nagkokonekta sa oil cylinder sa forklift door frame at hydraulic system, at dahan-dahang alisin ang oil cylinder. Sa panahon ng proseso, mag-ingat na huwag mabangga ang ibabaw ng cylinder cylinder at piston rod; ang pangalawang hakbang ay linisin ang mga bahagi. Gumamit ng hydraulic cleaner upang maingat na punasan ang panloob na dingding ng cylinder at ang ibabaw ng piston rod upang ganap na maalis ang langis at mga dumi, at suriin kung may pagkasira, mga gasgas at iba pang pinsala sa sealing groove; ang ikatlong hakbang ay palitan ang oil seal. Gumamit ng isang espesyal na tool upang dahan-dahang alisin ang lumang oil seal upang matiyak na walang natitirang mga fragment sa sealing groove. Ilagay ang bagong oil seal sa sealing groove sa tamang direksyon, at dahan-dahang pindutin ito gamit ang isang rubber martilyo o isang pressing tool upang maiwasan ang mga gasgas sa gilid ng oil seal. Ang ikaapat na hakbang ay ang pag-assemble ng oil cylinder. I-assemble ang mga bahagi ng silindro ng langis sa lugar ayon sa reverse order ng disassembly, at higpitan ang mga fixing bolts sa pagkakasunud-sunod. Ang metalikang kuwintas ay dapat matugunan ang mga kinakailangan ng kagamitan upang matiyak na ang mga bahagi ay magkasya nang mahigpit.

Mga hakbang sa pagpapalit ng pipeline: Ang unang hakbang ay suriin ang punto ng pagtagas ng langis. Sa pamamagitan ng pagmamasid sa mga bakas ng polusyon ng langis, tumpak na hanapin ang lokasyon ng pagtagas ng langis tulad ng maluwag na interface ng pipeline at pinsala sa pipeline, at pagkatapos markahan ito, alisin ang lumang pipeline; ang pangalawang hakbang ay linisin ang interface. Linisin ang mantsa ng langis sa interface sa pagitan ng silindro ng langis at ng hydraulic pump gamit ang isang detergent, alisin ang tumatandang gasket, at suriin kung ang mga thread ng interface ay buo; ang ikatlong hakbang ay ang pag-install ng bagong pipeline. Pumili ng bagong pipeline na may katugmang detalye, maglagay ng bagong gasket sa interface, ikonekta ang dalawang dulo ng pipeline sa interface sa pagitan ng oil cylinder at ng hydraulic pump ayon sa pagkakabanggit, at katamtamang higpitan ang mga bolts gamit ang isang wrench upang maiwasan ang pagpapapangit ng mga sinulid o pipeline na dulot ng labis na puwersa. Ang ikaapat na hakbang ay ang pagsubok sa presyon. Ibalik ang koneksyon ng hydraulic system, simulan ang forklift pagkatapos i-on ang power, subukan ang lifting function nang maraming beses, at obserbahan kung mayroon pa ring pagtagas ng langis sa cylinder at pipeline interface upang matiyak na ang kasalanan ay ganap na nalutas.

Matapos makumpleto ang pagpapanatili, inirerekumenda na regular na suriin ang lifting cylinder at hydraulic pipeline, linisin ang mantsa ng langis sa oras, at harapin ang abnormal na pagtagas ng langis sa lalong madaling panahon, upang pahabain ang buhay ng serbisyo ng silindro at tiyakin ang matatag na operasyon ng forklift.
