I-Motor Grader Esetshenzisiwe SEM919 Iyathengiswa

Isingeniso Somkhiqizo

I-SEM919 iwumkhiqizo we-motor grader we-Caterpillar's Shangong Machinery.Iwuhlobo lwemishini yokunyakazisa umhlaba.Ingasetshenziselwa ukwakhiwa komgwaqo, ukwakhiwa kwedolobha, kanye nokunye ukulungiswa komgwaqo kanye nezimo zokususa iqhwa.Uma ungeza Ngokungezwa kwe-ripper ngemuva kwe-dozer blade, umsebenzi owengeziwe ungenziwa.

Izici Zomkhiqizo

1. Isibungu i-asi yangemuva eyenziwe ekhaya

Isakhiwo sokuthwala esithuthukisiwe, ukusatshalaliswa komthwalo okunengqondo, nempilo ende;amabhuleki e-caliper disc, ukusebenza ngcono ngo-20%, okuthembekile kakhulu;ukuhlelwa kwamagiya angamaplanethi amane okushayela kokugcina, umthamo oqinile wokuthwala umthwalo;amabhuleki angaphandle, ukugcinwa okulula;azikho izidingo zokujova ugrisi, ukonga Isikhathi, umzamo kanye nemali kugcinwa.

2. Uhlelo lokulawula izimbobo ezinezimbobo eziyisikhombisa (kuyakhetheka)

Indlela yokuxhuma enezimbobo eziyisikhombisa elawulwa yi-electro-hydraulic ingashintsha indawo yembobo kukhebhu;ukusebenzisa indawo efanele yembobo kungaqinisekisa ukuthi i-blade ingakwazi ukuthinta phansi komsele lapho isusa izimila ezimila emgodini;Ukulungiswa kwendawo yembobo yenduku kungalungisa kangcono i-engeli phakathi kwe-blade nomhlabathi, okulungele ukulungisa umsele wokudonsa kanye nomthambeka ongemuva wosebe lomfula.Uma ibekwe endaweni yokugcina imbobo, i-blade ingafinyelela ama-degree angama-90 perpendicular emhlabathini, okulungele ukusebenza kwe-high-back slope;ama-bushings ashintshayo ajwayelekile emigodini yenduku yokuxhuma alungele ukugcinwa nokulungiswa, futhi anganciphisa isikhathi sesevisi nezindleko zokulondoloza.

3. Umsebenzi wokuntanta kwe-blade

Umsebenzi ojwayelekile wokuntanta we-blade wehlisa ubunzima bomsebenzi futhi uthuthukisa 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.

4. Isistimu ye-hydraulic ezwa ukulayisha

Ivalvu yokulawula ye-PPPC (I-Proportion Priority, Pressure Compensation) eklanywe ngokukhethekile i-Caterpillar ye-motor graders isabalalisa amandla ngokuvumelana nesidingo nokugeleza ngokwesilinganiso, iqinisekisa ukuthi umshayeli angasebenzisa umshini ukuze aqedele izenzo ezihlanganisiwe eziningi 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.

5. Thayipha ibha yokudonsa

Uhlaka lokudonsa lohlobo lwe-A lwakhiwe ngezinsimbi ezimbili eziyisikwele, ezinokuqina okuhle, impilo ende yesevisi kanye nezinga lokuhluleka eliphansi.Ikhanda lebhola lingakwazi ukulungisa igebe (i-gasket yokulungisa) ngokuya ngesimo sokuguga, ukunciphisa izindleko zokugcinwa komsebenzisi.Ikhanda lebhola lokuxhumana elikhiphekayo lihlanganiswe namabhawodi ukuze lingene esikhundleni kalula.

6. Uhlaka lwangaphambili lwesakhiwo sebhokisi

Idizayini yesakhiwo sohlobo lwebhokisi ene-flange igcina indawo enengcindezi ephezulu kude nomthungo we-weld, okuthuthukisa ukuthembeka nokuqina futhi andise 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. Isakhiwo sokukhohlisa esinengqondo

Ukuzuza njengefa isakhiwo se-joystick esisezingeni eliphezulu semboni, ukuhamba okufushane nezilawuli ezihlukaniswe kahle kuvumela opharetha ukuthi asebenzise izinti zokujabula eziningi ngesandla esisodwa.Amandla okulawula ukukhanya anciphisa ukukhathala komshayeli.

8. Ikhebhu evulekile nenethezekile

I-cab itholakala ohlakeni olungaphambili, futhi indawo yefreyimu yokudonsa, i-turntable ne-blade ibonakala ngokucacile, okuwusizo kumshayeli ukulawula indawo ye-blade ngokunembe kakhudlwana.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.
