Mfundo ya electro-hydraulic excavator steel grab machine ndikugwiritsa ntchito mphamvu yamagetsi kuti igwire ntchito kudzera mu hydraulic system kuti ikwaniritse kutsegula ndi kutseka kwa chidebe chogwira kuti akwaniritse cholinga chotsitsa ndi kutsitsa katundu.
Chinthu choyamba chomwe chimapangitsa kutentha kwamafuta kukwera ndi kapangidwe kopanda nzeru ka makina ophatikizira a electro-hydraulic.Mukagwira zinthu, kukana kwakuthupi kukakhala kwakukulu kuposa mphamvu yakukumba ya makina ogwirira, ngakhale chidebe chogwira sichingagwire zinthuzo, "chophwanyidwa" mu mulu wazinthu, koma injini ya makina ogwirira imazungulirabe, ndipo ngakhale galimoto ikuwoneka "yotsekedwa yozungulira", makina a hydraulic ali ndi valve yowonjezera kuti adziteteze.Panthawi imeneyi, mpope kudzera mpumulo valavu kuthamanga kusefukira, mafuta kutentha limatuluka kwambiri.Mphamvu zimasungidwa, ndipo mphamvu yamagetsi imakhala kutentha, kutenthetsa mafuta.
Pakutsitsa ndi kutsitsa ntchito, chifukwa cha zomwe wogwiritsa ntchitoyo adakumana nazo kapena mzere wowonera ndi zinthu zina, pitilizani kugwira chogwiriracho pambuyo pa kutsekedwa kwa makina onyamula zitsulo, kuti makina opangira zitsulo atsekedwenso (nthawi zambiri zimachitika), ndiye injini yamakina ogwiritsira ntchito zitsulo imatembenukabe, galimotoyo ikuwoneka "yotsekedwa", pampu ya hydraulic kudzera mu valve yopumulira yothamanga kwambiri, kutentha kwa mafuta kumakwera kwambiri.Mphamvu zimasungidwa, ndipo mphamvu yamagetsi imasanduka kutentha, kutenthetsa mafuta.
Kukwera kwa kutentha kwa mafuta sikungowononga mphamvu, komanso kumayambitsa ngozi zotsatirazi:
No.1: excavator litenge zitsulo makina ntchito si odalirika, osatetezeka.Kutentha kwamafuta kumakwera kwambiri, kukhuthala kwamafuta a hydraulic, mphamvu ya volumetric ndi hydraulic system yogwira ntchito bwino, kutayikira kumachulukira, kupanikizika sikungasungidwe, mphamvu yogwira yowala imakhala yaying'ono kapena yosagwira katundu, kudalirika ndikosavuta, kugwidwa kolemera kwa katundu kugwera mumlengalenga, kosatetezeka.
No.2: Zimakhudza kupanga.Chifukwa cha zomwe zili pamwambapa, wogwiritsa ntchito amayenera kuyimitsa ndikusiya kutentha kwamafuta a makina achitsulo chogwira kuzirala, zomwe zimakhudza mphamvu yotsitsa ndikutsitsa.
No.3: Zigawo za hydraulic system zimakula chifukwa cha kutenthedwa, kuwononga kusiyana kwapachiyambi komwe kumayenderana ndi ziwalo zomwe zikuyenda, zomwe zimapangitsa kuti pakhale mikangano yowonjezereka, valavu ya hydraulic ndi yosavuta kupanikizana, nthawi yomweyo, filimu yamafuta opaka mafuta. zimakhala zowonda, zovala zamakina zimawonjezeka, zomwe zimapangitsa kuti pampu, valavu, galimoto, ndi zina zotero, zigwirizane bwino, chifukwa cha kuvala msanga ndi kulephera kapena kutaya.
No.4: Mafuta vaporization, madzi evaporation, zosavuta kupanga hayidiroliki zigawo cavitation;Mafuta oxidize kuti apange ma colloidal deposits, omwe ndi osavuta kutsekereza mabowo mu fyuluta yamafuta ndi valavu ya hydraulic, kotero kuti ma hydraulic system sangathe kugwira ntchito bwino.
No.5: Kufulumizitsa ukalamba ndi kuwonongeka kwa zisindikizo za rabara, kufupikitsa moyo wawo, ngakhale kutaya ntchito yawo yosindikiza, zomwe zimapangitsa kuti ma hydraulic system atayike kwambiri.
No.6: Kutentha kwamafuta kwambiri kumathandizira kuwonongeka kwamafuta a hydraulic ndikufupikitsa moyo wantchito wamafuta
No.7: Kulephera kwa makina ogwiritsira ntchito zitsulo ndikwambiri, ndipo mtengo wokonza ukuwonjezeka.Kutentha kwambiri kwamafuta kumakhudza kwambiri kugwiritsa ntchito makinawo, kuchepetsa moyo wautumiki wa zida za hydraulic, kulephera kwakukulu, ndikuwonjezera mtengo wokonza.
Mwachidule, pankhani ya ndalama zokwanira, akatswiri amanena kuti ndi bwino kugula chofukula kuti akonzenso makina ogwiritsira ntchito zitsulo, ndikugwiritsanso ntchito makina a hydraulic ofukula kuti ayendetse makina ogwiritsira ntchito zitsulo, ndi ntchito yokhazikika komanso kuchepa kochepa !!
