Mafuta a hydraulic excavator ali pa kutentha kwakukulu, kotero kusefera ndi kuyeretsa ndikofunikira kwambiri

Kutentha kwakukulu kwa mafuta ofufutira a hydraulic kumagwirizana mwachindunji ndi kukonza kwa tsiku ndi tsiku ndi kusintha kwa mafuta. Kusintha pafupipafupi kwa sefa sikungathetse mavuto akulu chifukwa:

1. Malinga ndi miyezo ya mafuta pamakina omanga, kuchuluka kwa kuwonongeka kwa mafuta ambiri a hydraulic kuyenera kuwongoleredwa ku NAS ≤ 8. Mafuta atsopano a hydraulic akadzazidwa m'migolo pa malo opangira mafuta, kulondola kwa kusefera kumafunika kukhala 1 mpaka 3 microns.

2. Malinga ndi mapangidwe amafuta amafuta a hydraulic oil circuit yamakina a engineering, kusefera kulondola kwa fyuluta yamafuta a hydraulic kumatha kuchepetsedwa mpaka ≥10 microns, komanso kusefera kulondola kwa zinthu zosefera za zonyamula zina. ndi zazikulu. Ngati ili ndi ma microns osakwana 10, izi zidzakhudza kuthamanga kwa mafuta komanso kuthamanga kwagalimoto, ndipo ngakhale zinthu zosefera zidzawonongeka! Chisankho chomwe chimagwiritsidwa ntchito kwambiri pamakina a hydraulic oil filter pamakina a engineering ndi: kulondola kusefera ndi 10μm50%, kupanikizika ndi 1.4 ~ 3.5MPa, kutuluka kwake ndi 40 ~ 400L / min, ndipo nthawi yosinthira ndi 1000h.

3. Moyo wautumiki wa mafuta a hydraulic nthawi zambiri ndi 4000-5000h, yomwe ili pafupi zaka ziwiri. M'chaka ndi m'dzinja chaka chilichonse, kusiyana kwa kutentha pakati pa usana ndi usiku kumakhala kwakukulu. Wofukula akasiya kugwira ntchito usiku atagwira ntchito kwa tsiku limodzi, mafuta omwe ali mkati mwa tanki ya hydraulic amakhala kutentha kwambiri ndipo mpweya wakunja kwa thanki ndi kutentha kochepa. Mpweya wotentha wa mu thanki umakumana ndi mpweya wozizira kunja kwa thanki. Idzasungunuka kukhala madontho amadzi pamwamba pa thanki ndikugwera mumafuta a hydraulic. Pakapita nthawi, mafuta a hydraulic adzasakanizidwa ndi madzi. Kenako imasanduka chinthu cha acidic chomwe chimawononga pamwamba pazitsulo. Pansi pazigawo ziwiri zamakina ogwiritsira ntchito komanso kupanikizika kwa mapaipi, tinthu tating'onoting'ono timene timagwera pazitsulo zimasakanizidwa mumafuta a hydraulic. Panthawiyi, ngati mafuta a hydraulic sanayeretsedwe, tinthu tating'onoting'ono tazitsulo timasefedwa ndi fyuluta, ndipo tinthu tating'onoting'ono kuposa 10 μm tidzakhala hydraulically. zosefedwa zimasakanizidwa mumafuta a hydraulic ndipo zimakulitsa kuvalanso kwachitsulo pamwamba. Chifukwa chake, akatswiri amalimbikitsa kuti kusefera kwamafuta a hydraulic ndi nthawi yoyeretsedwa ndi maola 2000-2500 kapena kamodzi pachaka, ndipo m'malo mwa mafuta atsopano Muyeneranso kuyeretsedwa. Lolani mafuta akale mu dongosolo ayeretsedwe ndikusandulika kukhala mafuta atsopano, kenaka onjezerani mafuta atsopano, kuti mafuta otsalawo asawononge mafuta atsopano.

Popeza kusintha pafupipafupi kwa zosefera sikungathetse vutoli, tiyenera kuchita chiyani? Njira yabwino yothanirana nazo ndikusefa ndikuyeretsa mafuta mu thanki yamafuta ndi makina ozungulira mafuta ndi makina apadera a vacuum mafuta opangira ma hydraulic kuti achotse madzi ochulukirapo ndi zonyansa zamakina mumafuta ndikusunga mafuta a hydraulic oyera. Ukhondo umasungidwa pamlingo wa NAS6-8 kwa nthawi yayitali, ndipo chinyezi chimakhala mkati mwamtundu wadziko lonse. Mafuta amalamulidwa kuti asakalamba mosavuta, kotero kuti zipangizo zofukula zisawonongeke, mafuta amakhala olimba, ndipo kutaya zambiri ndi zowonongeka zingathe kupewedwa!

Pamene maola ogwirira ntchito ofukula akuchulukirachulukira, zida zambiri zokalamba zimafunikanso kusinthidwa munthawi yake. Ngati mukufuna kugulapofukula zowonjezera, mutha kulumikizana nafe. Ngati mukufuna kugula achofufutira chachiwiri, mutha kulumikizana nafe. CCMIE imakupatsani chithandizo chokwanira kwambiri chogulira.
