Forklift steering cylinder oil seal aging leakage, isang buong hanay ng mga tagubilin sa pag-aayos

Forklift steering cylinder oil seal aging leakage, isang buong hanay ng mga tagubilin sa pag-aayos(larawan1)

Ang steering cylinder ng electric forklift ay ang pangunahing bahagi upang matiyak ang flexibility ng pagpipiloto ng sasakyan. Bilang pangunahing bahagi ng sealing ng cylinder, ang oil seal ay madaling kapitan ng pagtanda at pagtagas dahil sa pangmatagalang impluwensya ng hydraulic oil erosion, mechanical friction at mga salik sa kapaligiran. Kung hindi ito mahawakan sa oras, hindi lamang nito tataas ang pagkawala ng hydraulic oil, ngunit hahantong din sa pagtaas ng steering resistance at pagbaba ng katumpakan, na makakaapekto sa normal na operasyon at maging sa kaligtasan ng operasyon ng forklift.

Bago simulan ang pag-aayos, kinakailangan upang tumpak na hatulan ang pagtanda at pagtagas ng oil seal. Sa araw-araw na inspeksyon, maaari mong bigyang-pansin kung mayroong tuluy-tuloy na akumulasyon ng oil film sa ibabaw ng piston rod ng silindro ng langis, kung may mga bakas ng mantsa ng langis sa frame at lupa sa paligid ng silindro ng langis, at sa sa parehong oras pakiramdam ang pagbabago ng lakas ng forklift kapag lumiliko. Ang pagkabigo ay humahantong sa pagtagas ng hydraulic oil at hindi sapat na presyon.

Bago gamitin ang buong hanay ng mga repair kit, kailangan mong maghanda. Una, iparada ang forklift sa isang patag at matatag na lugar, hilahin pataas ang handbrake at putulin ang power supply, at bitawan ang pressure relief valve ng hydraulic system upang maiwasan ang pag-spray ng hydraulic oil sa panahon ng proseso ng disassembly. Maghanda ng mga repair kit (kabilang ang mga inangkop na dust ring, pangunahing oil seal, auxiliary sealing ring, atbp.) at mga espesyal na tool, tulad ng sleeve wrenches, inner hexagonal screwdriver, hydraulic cylinder dismantling tools, cleaning cloth, atbp.

Sa panahon ng pormal na operasyon, ang unang hakbang ay alisin ang silindro ng langis. Gumamit ng jack upang suportahan ang harap ng forklift, suspindihin ang manibela sa hangin, alisin ang mga konektor sa pagitan ng dalawang dulo ng silindro ng langis, ang mekanismo ng pagpipiloto, at ang haydroliko na pipeline, at alisin ang silindro ng langis nang maayos. Hakbang 2 I-disassemble ang silindro ng langis: tanggalin ang takip sa dulo ng silindro ng langis, dahan-dahang bunutin ang piston rod, gumamit ng panlinis na tela upang punasan ang mga mantsa ng langis at mga sira na labi sa panloob na dingding ng silindro ng silindro at ang ibabaw ng piston rod, at mag-ingat upang maiwasan ang pagkamot sa ibabaw ng katumpakan. Ang ikatlong hakbang ay ang pagpapalit ng seal: ayon sa mga tagubilin ng mga bahagi sa repair bag, mag-install ng mga bagong dust-proof ring, pangunahing oil seal, at auxiliary seal ring sa pagkakasunud-sunod. Kapag nag-i-install, bigyang-pansin ang direksyon ng seal, at gumamit ng mga espesyal na tool upang tumulong sa pagtulak upang maiwasan ang pag-twist at Ang ika-apat na hakbang ay ang pag-assemble ng silindro ng langis: dahan-dahang i-install ang piston rod na pinahiran ng kaunting hydraulic oil sa cylinder, higpitan ang dulong takip at tiyaking pare-pareho ang puwersa ng pangkabit upang maiwasan ang hindi pantay na puwersa sa bahagi ng sealing. Hakbang 5 I-reload ang forklift: Ikonekta muli ang silindro sa mekanismo ng pagpipiloto at ang hydraulic pipeline, at suriin ang higpit ng lahat ng mga bahagi ng pagkonekta.

Matapos makumpleto ang pag-install, kinakailangan ang isang pagsubok. Simulan ang forklift, paandarin ang mekanismo ng pagpipiloto nang maraming beses, obserbahan kung may mga palatandaan ng pagtagas sa silindro ng langis, at pakiramdam kung ang puwersa ng pagpipiloto ay bumalik sa normal. Maaaring isagawa ang walang-load at light-load na mga pagsubok sa pagmamaneho sa ibang pagkakataon upang kumpirmahin na ang pagpipiloto ay nababaluktot at walang jamming, at ang pagganap ng sealing ay matatag. Sa panahon ng operasyon, dapat tandaan na ang lahat ng mga seal ay dapat hawakan nang may pag-iingat upang maiwasan ang mga gasgas mula sa matutulis na bagay.
