Forklift hydraulic oil pump abnormal na pag-troubleshoot ng ingay, pagsuporta sa mga kasanayan sa pagpapalit ng elemento ng filter ng pipeline(larawan1)

Ang hydraulic system ng electric forklift ay ang pangunahing bahagi upang matiyak ang pag-angat at paghawak nito. Ang mga problema tulad ng abnormal na ingay ng hydraulic oil pump at pagbara ng mga elemento ng filter ng pipeline ay hindi lamang makakaapekto sa kahusayan sa pagpapatakbo, ngunit maaari ring magpalala ng pagkasira ng mga bahagi at paikliin ang buhay ng serbisyo ng kagamitan. Ang pag-master ng abnormal na pag-troubleshoot ng ingay at mga kasanayan sa pagpapalit ng elemento ng filter ay isang mahalagang bahagi ng pang-araw-araw na pagpapanatili ng mga forklift.

1. Paano suriin ang abnormal na ingay ng hydraulic oil pump

Kapag ang hydraulic oil pump ay may abnormal na tunog, ang mga katangian ng abnormal na tunog ay dapat munang matukoy sa pamamagitan ng pandinig: kung mayroong isang matalim at malupit na pagsipol, ito ay kadalasang nauugnay sa kakulangan ng hydraulic oil intake o langis; kung ito ay isang malalim na muffled na tunog, ito ay maaaring sanhi ng pagkasira ng mga panloob na bahagi. O ang hydraulic valve ay natigil.

Ang unang hakbang ay suriin ang estado ng hydraulic oil. Buksan ang takip ng tangke ng hydraulic oil at obserbahan kung ang antas ng langis ay nasa pagitan ng itaas at mas mababang mga limitasyon ng ruler. Kung ang antas ng langis ay masyadong mababa, ang hydraulic oil ng parehong uri ay dapat na mapunan sa oras; sa parehong oras, suriin ang kulay at transparency ng langis. Kung ang langis ay itim, maulap o naglalaman ng mga impurities, Nangangahulugan ito na ang kalidad ng langis ay lumala at kailangang ganap na palitan.

Ang ikalawang hakbang ay suriin ang problema sa paggamit ng pipeline. Isa-isang suriin ang mga joints at seal ng hydraulic pipeline. Kung maluwag o nasira ang mga ito, higpitan o palitan ang mga seal sa oras; pagkatapos ay simulan ang forklift at paulit-ulit na paandarin ang mekanismo ng pag-aangat upang matulungan ang hangin sa pipeline na maubos at obserbahan kung ang abnormal na ingay ay naibsan.

Ang ikatlong hakbang ay suriin ang pagkasira ng oil pump. Kung ang abnormal na ingay ay umiiral pa rin pagkatapos maalis ang mga problema sa langis at paggamit, ang oil pump ay kailangang ihinto at i-disassemble upang suriin ang antas ng pagkasira ng mga panloob na gear, bearings at iba pang mga bahagi. Kung ang agwat sa pagitan ng mga bahagi ay lumampas sa karaniwang hanay, ang kaukulang mga bahagi ng pagsusuot ay kailangang palitan.

Ang ikaapat na hakbang ay upang i-verify ang kondisyon ng pagtatrabaho ng hydraulic valve. Suriin ang overflow valve, reversing valve at iba pang bahagi sa hydraulic system. Kung ang spool ay natigil o pagod, ito ay magdudulot ng abnormal na presyon ng langis at magdudulot ng abnormal na ingay ng oil pump. Sa oras na ito, ang spool ay kailangang linisin o palitan.

Pangalawa, ang mga kasanayan sa pagpapalit ng elemento ng filter ng hydraulic pipeline

Ang pangunahing pag-andar ng elemento ng filter ng hydraulic pipeline ay upang i-filter ang mga dumi sa langis upang maiwasan ang mga ito na makapasok sa oil pump at hydraulic valve. Ang regular na pagpapalit ng elemento ng filter ay ang susi sa pagpapanatili ng hydraulic system.

Una sa lahat, gumawa ng mga paunang paghahanda: iparada ang forklift sa patag na lupa, patayin ang kuryente at hilahin pataas ang handbrake, patakbuhin ang mekanismo ng pag-aangat upang mabawasan ang tinidor, dahan-dahang ilabas ang presyon ng hydraulic system, at iwasan ang pag-spray ng langis sa panahon ng disassembly; ihanda ang katugmang modelo Mga bagong filter, wrenches, oil receiving container at iba pang tool.

Pagkatapos ay isagawa ang kapalit na operasyon: hanapin ang lokasyon ng elemento ng filter, kadalasan sa gitna ng outlet ng langis o pipeline ng hydraulic oil tank, ilagay ang lalagyan ng langis sa ilalim ng elemento ng filter, tanggalin ang lumang elemento ng filter gamit ang isang wrench, at mag-ingat upang maiwasan ang pagtagas ng natitirang langis; punasan ito ng malinis na basahan Ang ibabaw ng upuan ng pag-install ng elemento ng filter ay tinitiyak na walang nalalabi na dumi; lagyan ng kaunting hydraulic oil ang sealing ring ng bagong elemento ng filter, at dahan-dahang i-screw ito sa installation seat hanggang sa ito ay masikip (nang walang labis na puwersa upang maiwasan ang pagkasira ng sealing ring).

Panghuli, kumpletuhin ang follow-up na inspeksyon: Pagkatapos makumpleto ang pag-install, magdagdag ng naaangkop na dami ng hydraulic oil sa karaniwang antas ng langis, simulan ang forklift at paulit-ulit na paandarin ang mekanismo ng pag-aangat upang maubos ang hangin sa pipeline; pagkatapos tumakbo ng 5-10 minuto, suriin kung mayroong anumang pagtagas ng langis sa lugar ng pag-install ng elemento ng filter, at sa parehong oras Obserbahan kung ang hydraulic system ay tumatakbo nang maayos, at maaari itong magamit pagkatapos makumpirma na walang abnormalidad.

Sa pang-araw-araw na pagpapanatili, inirerekumenda na regular na suriin ang mga kondisyon ng pagtatrabaho ng hydraulic oil pump at ang katayuan ng elemento ng filter ayon sa cycle na tinukoy sa manwal ng kagamitan, at suriin ang mga nakatagong panganib sa oras, upang epektibong pahabain ang buhay ng serbisyo ng hydraulic system at tiyakin ang matatag na operasyon ng forklift.
