Paano haharapin ang hindi sapat na presyon ng hydraulic oil pump? Mga mungkahi para sa sabay-sabay na pagpapalit ng pipeline ng elemento ng filter(larawan1)

Ang hydraulic oil pump ay ang pangunahing bahagi ng hydraulic system ng electric forklift. Kapag nagkaroon ng problema sa hindi sapat na presyon, ito ay direktang hahantong sa mabagal o kahit na pagkabigo sa pag-angat at pagtabingi ng forklift, na makakaapekto sa kahusayan at kaligtasan ng operasyon. Kapag nakakaranas ng ganitong mga pagkakamali, kinakailangang suriin at harapin ang mga ito nang sunud-sunod, at kasabay nito ay bigyang-pansin ang sabay-sabay na pagpapalit ng elemento ng filter at pipeline upang malutas ang problema mula sa ugat.

Una sa lahat, ang isang pangunahing pagsusuri ng hydraulic system ay kinakailangan. Suriin muna ang antas ng likido at kalidad ng hydraulic oil. Kung ang antas ng likido ay mas mababa kaysa sa karaniwang halaga, lagyang muli ang hydraulic oil na nakakatugon sa mga detalye sa oras; kung ang langis ay maulap, itim o naglalaman ng mga dumi, nangangahulugan ito na ang langis ay lumala at kailangang palitan ng buo. Pagkatapos ay suriin kung may mga leakage point sa system, na tumutuon sa pagsuri sa oil pump seal, pipeline joints, hydraulic cylinder seal at iba pang bahagi. Kung may nakitang leakage, palitan ang mga nasirang seal sa oras at higpitan ang mga joints.

Matapos alisin ang mga problema sa langis at pagtagas, kinakailangang tumuon sa estado ng elemento ng filter at pipeline. Ang pangmatagalang paggamit ng elemento ng hydraulic filter ay mag-iipon ng malaking halaga ng mga dumi, na hahadlang sa sirkulasyon ng langis pagkatapos ng pagbara, na magreresulta sa pagbaba sa presyon ng output ng oil pump; habang ang tumatandang pipeline ay maaaring magkaroon ng kaagnasan, pagpapapangit o lokal na pagbara sa panloob na dingding, na makakaapekto rin sa paghahatid ng presyon. Sa oras na ito, ang pagpapalit lamang ng elemento ng filter o pagpapalit lamang ng pipeline ay hindi ganap na malulutas ang problema-ang natitirang mga dumi ng pipeline ay haharang muli sa bagong elemento ng filter, at ang pagbara ng lumang elemento ng filter ay maaari ring marumi ang bagong pipeline, na bumubuo ng isang mabisyo na bilog.

Samakatuwid, inirerekumenda na palitan ang elemento ng filter at pipeline nang sabay-sabay. Bago ang pagpapalit, kinakailangan na ihinto ang makina at bitawan ang presyon ng hydraulic system upang maiwasan ang panganib na dulot ng pag-spray ng langis. Kapag pinapalitan, alisin muna ang lumang elemento ng filter at ang tumatandang pipeline, at linisin ang interface ng oil pump at mga nakapaligid na dumi; kapag nag-i-install ng bagong pipeline, tiyaking mahigpit na konektado ang mga joints upang maiwasan ang pagtagas; kapag nag-i-install ng bagong elemento ng filter, bigyang-pansin ang tamang pagkakalagay sa direksyon ng pagmamarka upang maiwasan ang reverse installation. Nakakaapekto sa epekto ng pagsasala. Pagkatapos makumpleto ang pagpapalit, simulan ang forklift upang magsagawa ng walang-load na pagsubok upang obserbahan kung maayos ang pag-angat at pagtabingi. Kasabay nito, gamitin ang pressure gauge upang makita ang output pressure ng oil pump at kumpirmahin na ang presyon ay bumalik sa karaniwang hanay.

Sa pang-araw-araw na pagpapanatili, kinakailangan ding regular na suriin ang katayuan ng elemento ng filter at pipeline, at bumalangkas ng cycle ng pagpapalit ayon sa kapaligiran ng pagtatrabaho at dalas ng paggamit, upang mabawasan ang paglitaw ng hindi sapat na presyon ng hydraulic oil pump mula sa pinagmulan at pahabain ang buhay ng serbisyo ng kagamitan.
