I-SEM921 i-self-propelled motor grader

Isingeniso Somkhiqizo

I-SEM921 i-self-propelled motor grader ifakwe nephampu ye-plunger eguquguqukayo ye-Rexroth engenisiwe njengejwayelekile, esabalalisa ukugeleza ngokufunwa futhi yonga ukusetshenziswa kwamandla;Ukubaluleka kwesilinganiso esiyingqayizivele se-Caterpillar kanye ne-valve yokulawula isinxephezelo sokucindezela (PPPC) kwenza isilawuli somshini sizwele kakhulu futhi sithuthukise ukusebenza kukonke komshini.ukusebenza nokusebenza kahle.

Izici Zomkhiqizo

1. I-SEM921 motor grader yamukela isistimu ye-hydraulic ezwa ukulayisha ehamba phambili ngokulinganayo kanye nesinxephezelo sokucindezela, esihlinzeka ngokunyakaza kwamathuluzi okubikezelwayo nokunembayo, ukuthuthukisa izinga lomsebenzi nokusebenza kahle komsebenzi, futhi uhlaka lwamukela isakhiwo esimise okwebhokisi esinama-flange, kanye neCaterpillar ngokwayo. -yenziwe I-axle yangemuva iqinisekisa ukuthi umshini unamandla futhi uhlala isikhathi eside, i-cab yinde futhi ivulekile, futhi i-air conditioner evamile ikhululekile;amandla aphansi okukhohlisa kanye ne-stroke kunciphisa ukukhathala komshayeli.

2. I-asi engemuva ye-Caterpillar eyazakhela yona ngokwayo ithuthukisa ukuhlelwa kokuthwala, isabalalisa imithwalo ngokunengqondo, futhi ithuthukisa ukuphila;amabhuleki e-caliper disc athuthukisa ukusebenza ngo-20% futhi anokwethenjelwa kakhulu;amagiya amaplanethi amane ahlela ukushayela kokugcina, okunamandla okuthwala okunamandla;amabhuleki angaphandle, ukugcinwa Kalula;awudingi umjovo wamafutha, ukonga isikhathi, umsebenzi kanye nemali.

3. I-electro-hydraulic elawulwa yi-electro-hydraulic linkage mechanism inezimbobo eziyisikhombisa ingaqedela ukushintsha indawo yembobo kukhebhu.Ukusebenzisa indawo efanelekile yomgodi kungaqinisekisa ukuthi i-blade ingafinyelela phansi komsele lapho ususa uhlaza olukhule kakhulu emgodini.Ngokulungiswa kwesikhundla somgodi wenduku yokuxhuma, i-angle phakathi kwe-blade nomhlaba ingalungiswa kangcono, okuyinto elula ukulungisa umsele wokudonsa kanye nomthambeka ongemuva wosebe lomfula.Uma ibekwe ekugcineni kwembobo, i-blade ingafinyelela kuma-degree angama-90 perpendicular phansi, okulungele ukusebenza kwe-slope ephezulu emuva.Ama-bushings ashintshwayo ajwayelekile kubhore yenduku yokuxhuma ukuze alungiswe kalula futhi alungiswe, kuncishiswe isikhathi sesevisi kanye nezindleko zokuyilungisa.

4. Umsebenzi ontantayo we-blade ufakwe njengokujwayelekile, okunciphisa ubunzima bomsebenzi futhi kuthuthukise ukusebenza kahle komsebenzi.Lapho amasilinda kawoyela aphindwe kabili entanta ngesikhathi esifanayo, i-blade incike kumandla ayo adonsela phansi ukuze ibambelele phansi futhi yehle futhi yehla ngokuhlehlisa phansi ukuze ivikele umgwaqo oqinile.Isetshenziselwa ukususa iqhwa kanye nokususa udoti emgwaqeni.Isilinda esisodwa sokuphakamisa siyantanta, esingenza uhlangothi olulodwa lwe-blade lusondele endaweni yokusebenza kanzima, kanti olunye uhlangothi lwesilinda esiphakamisayo lusetshenziselwa ukulawula ukuthambekela kwe-blade.

5. I-PPPC (I-Proportion Priority, Pressure Compensation) i-valve yokulawula eyakhelwe ngokukhethekile i-Caterpillar ye-motor graders ihambisa amandla ngokuvumelana nesidingo nokugeleza ngokwesilinganiso, iqinisekisa ukuthi umshayeli angasebenzisa umshini ukuze aqedele izenzo eziningi ezihlanganisiwe futhi athuthukise ngokuphawulekayo ukusebenza kahle komsebenzi.Iphampu ye-plunger eguquguqukayo isetshenziselwa ukunciphisa ukulahleka kwamandla, ukunciphisa ukushisa okukhiqizwa isistimu ye-hydraulic, nokunciphisa ukusetshenziswa kukaphethiloli.Ama-hydraulic ezwa ukulayisha ahlinzeka ngokunyakaza okusebenzayo okubikezelwe, okunembe ukuze kuthuthukiswe izinga lomsebenzi kanye nokukhiqiza.I-valve ye-PPPC ine-valve yokukhiya eyakhelwe ngaphakathi ukuvimbela ukuvuza kwangaphakathi kwe-valve core, ukugcina isikhundla sethuluzi lomshini lapho kungekho ukusebenza kwe-hydraulic, nokuqinisekisa ikhwalithi yomsebenzi;vimbela ukuhamba ngengozi kwethuluzi lomshini futhi ugweme ukulimala ngengozi kubasebenzi.

6. Umklamo wesakhiwo omise okwebhokisi nge-flange ugcina indawo yokucindezeleka okuphezulu kude nomthungo we-weld, okuthuthukisa ukuthembeka nokuqina futhi kwandise impilo yesevisi yezingxenye zesakhiwo.Isakhiwo esiqhubekayo sepuleti elingaphezulu nephansi linikeza amandla amahle angaguquki futhi lithobelana ngokugcwele nezidingo zedizayini yezingxenye zesakhiwo se-Caterpillar, ezingandisa impilo yohlaka lwangaphambili futhi zehlise izindleko zokusebenzisa.Amapayipi ahlelwe ohlangothini lwefreyimu yangaphambili ukuze agcinwe kalula.Izingxenye ezibalulekile zisebenzisa izihlahla ezizigcobayo ukuze zithuthukise ukwethembeka kanye nokunciphisa izindleko zokunakekela.

7. I-cab itholakala kuhlaka lwangaphambili, futhi indawo yefreyimu ye-traction, i-turntable kanye ne-blade ingabonakala ngokucacile, okuwusizo kumshayeli ukulawula isikhundla se-blade ngokunembile.Yinde futhi ivulekile (ukuphakama kwamamitha angu-1.9), ingasebenza imile, futhi umthamo wayo ukhudlwana ngo-30%.Isiteringi samasondo angaphambili sibonakala kahle uma ukhalo lugobile, ukuqinisekisa ukuphepha nokunemba komsebenzi.
