Esetshenziswa 2021 XCMG XE80DA excavators ezinamasondo

Isingeniso Somkhiqizo

I-XCMG XE80DA Excavator isetshenziswa kabanzi kubunjiniyela bomhlaba omncane, ukwakhiwa kukamasipala, ukulungisa imigwaqo, ukuchotshozwa kukakhonkolo, ukungcwaba ikhebula, ukwakhiwa kwendawo yokongiwa kwamanzi epulazini, ukutshalwa kwengadi kanye nokumbiwa komsele womfula kanye namanye amaphrojekthi.

Izici zomkhiqizo

1. Yamukela injini ye-Yanmar eshiwo ngokwemvelo esetshenziswa kabanzi embonini, enokufuduka okuncane, ukusetshenziswa kukaphethiloli okuphansi kanye ne-torque enesivinini esiphansi, ehlangabezana ngokuphelele nezici zezimo zokusebenza ze-excavator.Injini isebenzisa ubuchwepheshe bomjovo oqondile futhi inokuguquguquka okuhle kukawoyela.Ithuthukisiwe kusuka kumthethonqubo wejubane lomshini kuya kumthethonqubo wejubane we-elekthronikhi, ukulawulwa kwejubane kuzinzile, okungagcini nje ukunciphisa ukusetshenziswa kukaphethiloli, kodwa futhi kunciphisa ngokuphumelelayo "umusi omnyama" wenjini.

2. Ngokokuqala ngqa embonini yomkhiqizo ofanayo we-tonnage, iphampu eyinhloko elawulwa nge-elekthronikhi isetshenziselwa ukulawula umthamo omkhulu we-torque yepompo eyinhloko ngokuya nge-torque ephezulu ephumayo yenjini ngesivinini esihlukile, ibona ngempela ukufana okuphelele phakathi umthwalo kanye nokuphuma kwamandla, kanye nokwenza ngcono kakhulu izinga lokusebenzisa amandla enjini .

3. Uhlelo lokulawula i-hydraulic lusebenzisa uhlelo oluthuthukisiwe lokulawula umthwalo olunamandla aphansi, ukuphendula okusheshayo, ukulawula okunembile kanye nomthelela omncane.Ngokuvumelana nesignali yempendulo yomthwalo, ukugeleza kokuphumayo kwephampu ye-plunger eguquguqukayo kulawulwa ukuze kuhlangane njalo nokuvuleka kwe-spool ye-valve yezindlela eziningi, ngaphandle kokulahlekelwa kokugeleza okungafuneki, kanye nokuzuza ukusatshalaliswa kokugeleza ngaphandle komthwalo, okungaphezulu. nezimo futhi flat.Izenzo kulula ukuzisebenzisa.

4. Uma kuqhathaniswa nemikhiqizo yochungechunge lwe-C, isizukulwane esisha i-XE80D inomthamo wamabhakede okhuphuke ngo-10% kuya ku-0.33m3, okuthuthukisa ukusebenza kahle kokusebenza komhlaba.Umthamo omkhulu wethangi likaphethiloli, kuhlanganiswe nokusetshenziswa kukaphethiloli okuphansi kakhulu, kwandisa isikhathi sokusebenza esiqhubekayo sawo wonke umshini.Ngokohlelo lwe-hydraulic oluthuthukisiwe noluthuthukisiwe, umthamo wethangi likawoyela we-hydraulic ulungiswa kabusha, ongaphansi ngo-11% kunalowo wemikhiqizo yochungechunge lwe-C, futhi izindleko zokulilungisa zehliswa kakhulu.

5. Ukuqiniswa okuyingxenye kwenziwa engxenyeni ye-boom ngokucindezeleka okukhulu.Induku yenziwe “ngepuleti elimise okwe-U” elibunjiwe kanye necwecwe elingaphezulu lekhava, elinempilo ende yesevisi.Ibhakede elisha elijwayelekile lenza ukulayisha kube lula.I-beam eyinhloko yesikhulumi sokuhlaba ithatha isakhiwo se-"I-beam", futhi i-beam eseceleni ithatha isakhiwo se-"D-shaped cross-section" isakhiwo esinokwethenjelwa okuphezulu okuphelele.Isakhiwo se-chassis ye-X siyamukelwa, futhi ingaphakathi lefreyimu engezansi liqiniswa ngezimbambo ukuze kwakhiwe ibhokisi lesigaba esikhulu, elinomsebenzi omuhle wokuthwala umthwalo futhi lingasebenzisa ngokulinganayo isisindo semoto engaphezulu emgqeni wethrekhi, ukunciphisa ukugxila kwengcindezi yendawo ye-beam yethrekhi..Isiseshi esiqinisiwe esijwayelekile samazwe ngamazwe siyamukelwa, esithembeke kakhulu ekusetshenzisweni futhi esilula kakhulu ekulungisweni.Isihlungi sangaphambili sokungenisa umoya esisanda kufakwa singakwazi ukuhlunga ngempumelelo izinhlayiya ezinkulu zokungcola kusihlungi somoya, sandise impilo yesevisi yesihlungi somoya.Ifakwe isihlungi esikhulu se-Euro III esinembayo esinesehlukanisi samanzi samafutha, indawo yokuhlunga iyizikhathi ezingu-1.5 kunezinye izinhlobo zethoni efanayo.
