Chofukulacho chikagwira ntchito kwa nthawi ndithu, ma silinda a mikono ikuluikulu ndi yaing’ono adzasanduka mitundu, makamaka makina akale.Kusintha kwamtundu ndikovuta kwambiri.Anthu ambiri sadziwa chomwe chikuyambitsa, ndipo amaganiza kuti ndi vuto laubwino wa silinda.
Kusintha kwamtundu wa silinda yamafuta ndi chinthu chodziwika bwino.Pali zifukwa zambiri, ndipo zifukwa zambiri za mtunduwo sizikugwirizana ndi mtundu wa silinda.Chotsatirachi ndichidule chachidule cha chofufutira cha Komatsu pc228 chomwe chakonzedwa posachedwa ndi ogwira ntchito yokonza fakitale.Tiyeni tikambirane chifukwa cha mtundu wa cylinder excavator ndi yankho.
Chochitika chavuto:
Wofukula wa Komatsu pc228 kasitomala, silinda yamafuta yamakina idasintha mtundu (silinda yamafuta inali yakuda), ndipo mafuta a hydraulic adasinthidwa ndi kampaniyo.Zinangotenga maola oposa 500 okha.Sindikudziwa chomwe chikuchitika?
Kulephera kusanthula kwa mtundu wa silinda yofukula (silinda yakuda):
Kawirikawiri, mtundu wa silinda umasinthidwa.Poyamba, silinda idzawoneka buluu, ndiye mtunduwo udzadetsedwa pang'onopang'ono kenako nkukhala wofiirira, mpaka utakhala wakuda.
Ndipotu, kusinthika kwa silinda sikuli chifukwa cha mankhwala omwewo, koma pamwamba pake amaphimbidwa ndi filimu yamitundu, kotero zikuwoneka ngati silindayo yatayika.Tiyeni tikambirane kaye zifukwa zosinthira mtundu wa silinda.
1. Kusiyana kwakukulu kwa kutentha pakati pa mkati ndi kunja kwa silinda
Izi nthawi zambiri zimachitika m'nyengo yozizira.Pambuyo pofukula ntchito kwa nthawi yayitali, kutentha kwa hydraulic system kumakwera, ndipo kutentha kwa chilengedwe chakunja kumakhala kotsika kwambiri.Panthawiyi, pali kusiyana kwakukulu kwa kutentha pakati pa mkati ndi kunja kwa silinda.Ndodo ya silinda ili mu mkhalidwe uwu.Kugwira ntchito pansi kungapangitse kuti silinda isinthe mtundu.
2. Ubwino wa mafuta a hydraulic ndi osauka kwambiri
Posintha mafuta a hydraulic of excavator, kuti apulumutse ndalama, mabwana ambiri samagula mafuta oyambira a hydraulic, omwe angapangitse kuti silinda isinthe mtundu.Chifukwa mafuta a hydraulic adzawonjezera kupanikizika kwakukulu kwa anti-wear additive, ma hydraulics a mitundu yosiyanasiyana ya opanga Chiŵerengero cha zowonjezera mu mafuta ndizosiyana, kotero kusakaniza kumayambitsa kutayika komanso kukhudza dongosolo la hydraulic.
3. Pamwamba pa ndodo ya silinda pali zonyansa
Pamene chofukula chikugwira ntchito, ndodo ya silinda ya silinda ya hydraulic nthawi zambiri imakhudzana ndi chilengedwe chakunja, ndipo n'zosavuta kumamatira ku fumbi ndi zonyansa, makamaka m'mikhalidwe yovuta, yomwe idzakhala yovuta kwambiri.Ngati sichitsukidwa mu nthawi, kudzikundikira kwa fumbi ndi zonyansa kumapangitsanso kuti silinda isinthe mtundu .
Ngati itembenuka kukhala buluu, imatha chifukwa cha zowonjezera mu chisindikizo chamafuta ndi mafuta a hydraulic omwe amamatira ku ndodo ya silinda pa kutentha kwakukulu.Zikasanduka zakuda, zitha kukhala kuti chitsogozo chomwe chili mumkono wovala chimangiriridwa pa silinda.Chifukwa pamtengo.
4. Pamwamba pa ndodo ya silinda pali mizere yabwino
Palinso kuthekera kwina kuti mtundu wa ndodo ya silinda ndi wolakwika.Pamwamba pa ndodo ya silinda imakhala ndi ming'alu ndi mizere yabwino yomwe imakhala yovuta kuipeza ndi maso.Chifukwa chachikulu ndi chakuti pamwamba pa ndodo ya pisitoni sichitenthedwa mofanana panthawi ya electroplating, ndipo ming'alu idzawoneka.Mkhalidwe wa chitsanzo.Izi zimangopezeka ndi galasi lokulitsa lamphamvu kwambiri.
Titakambirana zomwe zimayambitsa kusinthika pamwambapa, tiyeni tikambirane njira yothetsera kusungunuka kwa silinda yofukula (silinda ndi yakuda):
1.Ngati mupeza kuti pamwamba pa silinda ili ndi mtundu waung'ono ndi wochepa wa buluu, mukhoza kuusiya.
2. Ngati muwona kuti kutayika kwamtundu ndi koopsa kwambiri, muyenera kusintha chisindikizo chatsopano cha mafuta ndi kuvala manja, ndikuyang'ana dongosolo la hydraulic panthawi imodzimodzi kuti mupewe kutentha kwakukulu kwa mafuta a hydraulic.Izi nthawi zambiri zimatha pakapita nthawi.
3.Ngati theka lakutsogolo la cylinder ya ndowa likutayika, zikutanthauza kuti kutentha kwa mafuta a hydraulic ndipamwamba kwambiri, ndipo tifunika kuyeretsa radiator mokwanira kuti tichepetse kutentha kwa mafuta a hydraulic panthawi ya ntchito.
4. Ngati silinda imatayika pambuyo posintha mafuta a hydraulic amtundu wina, mafuta oyambirira a hydraulic ayenera kusinthidwa nthawi yomweyo panthawiyi.
5. Ngati kusintha kwamtundu kumayamba chifukwa cha kusweka kwa silinda, ili ndilo vuto la silinda.Ngati n'kotheka, gwirizanitsani ndi wothandizira wopanga kuti athetse, kapena gulani silinda yowonjezera nokha.
Mwachidule, pali zifukwa zambiri za mtundu wa silinda, zina zomwe zimayambitsidwa ndi chilengedwe chakunja, ndipo zifukwa zazikuluzikulu ndizo mavuto awo.Mwachitsanzo, ubwino wa mafuta a hydraulic, kutentha kwa mafuta a hydraulic, khalidwe la silinda, ndi zina zotero, kwenikweni, zonsezi zimafuna kuti tipeze Nkhani zina zomwe zimafunika kuziganizira pakukonzekera tsiku ndi tsiku.
Kusintha kwa mtundu wa silinda ndi chenjezo laling'ono chabe loti ma hydraulic system sakuyenda bwino.Mukapeza kuti simungathe kulumala, muyenera kuyang'ana makina a hydraulic mosamala ndikuwunika zomwe zili pamwambapa kuti muwone komwe kuli vuto.Ndikhulupirira kuti mukakumana ndi zolephera zofananira m'tsogolomu, mudzadziwa kuchokera pazifukwa ziti?Tiyeni tithane ndi vuto!
Kuphatikiza apo, kampani yathu imapereka mitundu yonse ya masilinda amtundu wa excavator.Ngati mukufuna kusintha silinda ya excavator, mutha kulumikizana nafe nthawi iliyonse.
