Intshayelelo yeMveliso

I-SEM921 i-self-propelled motor grader ixhotyiswe ngempompo yeplunger eguquguqukayo ye-Rexroth njengomgangatho, ehambisa ukuhamba ngokufunwa kwaye igcine ukusetyenziswa kwamandla;Ukubaluleka komlinganiselo okhethekileyo weCaterpillar kunye nevalve yokulawula imbuyekezo yoxinzelelo (PPPC) yenza ukuba umatshini ulawuleke ngakumbi kwaye uphucule ukusebenza ngokubanzi komatshini.ukusebenza kunye nokusebenza kakuhle.

Iimpawu zeMveliso

1. I-SEM921 i-motor grader ithatha inkqubo ye-hydraulic evavanya umthwalo ngokuphambili ngokulinganayo kunye nembuyekezo yoxinzelelo, ebonelela ngentshukumo yesixhobo eqikelelwayo kunye nechanekileyo, iphucula umgangatho womsebenzi kunye nokusebenza kakuhle, kunye nesakhelo samkela isakhiwo esinebhokisi eneflange, kunye neCaterpillar self. -yenziwe I-axle yangasemva iqinisekisa ukuba umatshini unamandla kwaye uqinile, i-cab ide kwaye ibanzi, kwaye i-air conditioner eqhelekileyo ikhululekile;amandla okulawula asezantsi kunye ne-stroke kunciphisa ukudinwa komqhubi.

2. I-asi yangemva yeCaterpillar eyenziwe ngokwayo iphucula ilungiselelo lokuthwala, isasaze imithwalo ngokufanelekileyo, kwaye iphucula ubomi;iibhuleki ze-caliper disc ziphucula ukusebenza nge-20% kwaye zithembeke ngakumbi;iigiya ezine zeplanethi zilungiselela i-drive yokugqibela, enomthamo onamandla wokuthwala;iziqhoboshi zangaphandle, ugcino Lulula;akukho naliti yegrisi efunekayo, ukonga ixesha, umsebenzi kunye nemali.

3. Isixhobo sokudibanisa i-electro-hydraulic esinemingxuma esixhenxe sinokugqibezela indawo yokutshintsha umngxuma kwikhebhu.Ukusebenzisa indawo efanelekileyo yomngxuma kunokuqinisekisa ukuba incakuba inokufikelela ezantsi komsele xa kucolwa uhlaza olukhule kakhulu emseleni.Ngokuhlengahlengiswa kwesithuba somngxuma wentonga yokudibanisa, i-angle phakathi kwe-blade kunye nomhlaba inokulungiswa ngcono, ekulungele ukulungiswa komsele wokukhupha kunye ne-back slope yonxweme lomlambo.Xa ibekwe emngxunyeni wokugqibela, i-blade inokufikelela kwi-90 degrees perpendicular emhlabeni, ekulungele ukusebenza kwe-slope back back.I-bushings enokutshintshwa isemgangathweni kwi-rod bore yokudibanisa ukuze kube lula ukugcinwa nokulungiswa, ukunciphisa ixesha lenkonzo kunye neendleko zokugcina.

4. Umsebenzi ojikelezayo we-blade uxhotyiswe njengomgangatho, onciphisa ubunzima bomsebenzi kunye nokuphucula ukusebenza kakuhle.Xa iisilinda zeoli eziphindwe kabini zidada ngaxeshanye, iblade ixhomekeke kubunzima bayo ukuze ibambelele emhlabeni kwaye ihambe inyuka iphantsi kunye nokuthotywa komhlaba ukukhusela indlela enzima.Isetyenziselwa ukususwa kwekhephu kunye nokususwa kwenkunkuma yendlela.I-cylinder eyodwa yokuphakamisa iyadada, enokuthi yenze elinye icala le-blade lisondele kwindawo esebenza nzima, kwaye elinye icala le-cylinder yokuphakamisa lisetyenziselwa ukulawula ukuthambekela kwe-blade.

5. I-PPPC (i-Proportion Priority, i-Pressure Compensation) i-valve yokulawula eyenzelwe ngokukodwa i-Caterpillar ye-motor graders ihambisa amandla ngokwemfuno kunye nokuhamba ngokomlinganiselo, ukuqinisekisa ukuba umqhubi unokusebenzisa umatshini ukugqiba izenzo ezininzi ze-compound kunye nokuphucula kakhulu ukusebenza kakuhle komsebenzi.Impompo yeplunger eguquguqukayo isetyenziselwa ukunciphisa ukulahleka kwamandla, ukunciphisa ubushushu obuveliswa yinkqubo ye-hydraulic, kunye nokunciphisa ukusetyenziswa kwamafutha.Ii-hydraulics ezijonga umthwalo zibonelela ngokuqikelelwa, ukuphunyezwa kwentshukumo echanekileyo yokuphucula umgangatho womsebenzi kunye nemveliso.I-valve ye-PPPC ine-valve yokukhiya eyakhelwe-ngaphakathi ukukhusela ukuvuza kwangaphakathi kwe-valve core, ukugcina indawo yesixhobo somatshini xa kungabikho ukusebenza kwe-hydraulic, kunye nokuqinisekisa umgangatho womsebenzi;thintela ukuhamba ngengozi kwesixhobo somatshini kwaye ugweme ukulimala ngengozi kubasebenzi.

6. Uyilo lwesakhiwo esinebhokisi esine-flange sigcina indawo yoxinzelelo oluphezulu kude ne-weld seam, ephucula ukuthembeka kunye nokuqina kunye nokwandisa ubomi benkonzo yeengxenye zesakhiwo.Ukwakhiwa kweplate eqhubekayo ephezulu kunye nezantsi kunika amandla afanelekileyo ahambelanayo kwaye ihambelana ngokupheleleyo neemfuno zokuyila iinxalenye zesakhiwo seCaterpillar, ezinokwandisa ubomi besakhelo sangaphambili kunye nokunciphisa iindleko zokusetyenziswa.Imibhobho ihlelwe kwicala lesakhelo sangaphambili ukwenzela ukugcinwa lula.Amacandelo aphambili asebenzisa i-self-lubricating bushings ukuphucula ukuthembeka kunye nokunciphisa iindleko zokugcina.

7. I-cab ibekwe kwisakhelo sangaphambili, kwaye indawo yesakhelo sokutsalwa, i-turntable kunye ne-blade inokubonwa ngokucacileyo, oku luncedo kumqhubi ukulawula indawo ye-blade ngokuchanekileyo.Ide kwaye ibanzi (i-1.9 yeemitha ukuphakama), inokuqhutywa imile, kwaye umthamo wayo ngu-30% omkhulu.Ukulawulwa kwamavili angaphambili kunokubonwa ngokucacileyo xa isinqe sigobile, siqinisekisa ukhuseleko kunye nokuchaneka komsebenzi.
