Isetyenziselwe iMotor Grader SEM919 iyathengiswa

Intshayelelo yeMveliso

I-SEM919 yimveliso yodidi lwemoto yoomatshini baseCaterpillar's Shangong.Luhlobo lomatshini wokushukuma komhlaba.Ingasetyenziselwa ulwakhiwo lwendlela, ukwakhiwa kwedolophu, kunye nokugcinwa kweendlela ezikhawulezayo kunye neemeko zokususa ikhephu.Ukuba uyongeza Ngokudityaniswa kwe-ripper emva kwe-dozer blade, umsebenzi omningi unokwenziwa.

Iimpawu zeMveliso

1. I-asi yangemva yecaterpillar eyenziwe ekhaya

Ukuphuculwa koyilo lokuthwala, ukuhanjiswa komthwalo okufanelekileyo, kunye nobomi obude;i-caliper disc brakes, ukusebenza kuphuculwe nge-20%, kunokwethenjelwa ngakumbi;Ulungiselelo lwezixhobo ezine zeplanethi zokuqhuba kokugqibela, amandla okuthwala umthwalo owomeleleyo;iziqhoboshi zangaphandle, ukugcinwa lula;akukho mfuneko yokutofa igrisi, ukonga Ixesha, umzamo kunye nemali zigcinwa.

2. Inkqubo yokulawula intonga enemingxuma esixhenxe (ukhetho)

Indlela yokudibanisa imingxuma esixhenxe elawulwa yi-electro-hydraulic inokutshintsha indawo yomngxuma kwi-cab;ukusebenzisa indawo efanelekileyo yomngxuma kunokuqinisekisa ukuba i-blade inokubamba ezantsi komsele xa ucoca utyani obukhule kakhulu emseleni;Ukulungelelaniswa kwesithuba somngxuma wentonga kunokulungelelanisa ngakumbi i-angle phakathi kwe-blade kunye nomhlaba, okulungele ukulungisa umsele wokukhupha amanzi kunye ne-slope yangasemva yomlambo womlambo.Xa ibekwe kwindawo yokuphela komngxuma, i-blade inokufikelela kwi-90 degrees perpendicular emhlabeni, ekulungeleyo kwimisebenzi ye-slope ephezulu;i-bushings eguquguqukayo eqhelekileyo kwimingxuma yentonga yokudibanisa ilungele ukulungiswa nokulungiswa, kwaye inokunciphisa ixesha lenkonzo kunye neendleko zokugcina.

3. Iblade edadayo umsebenzi

Umsebenzi osemgangathweni we-blade odadayo unciphisa ubunzima bomsebenzi kwaye uphucula 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.

4. Inkqubo yovandlakanyo lwe-hydraulic

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.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.

5. Chwetheza i-drawbar

Uluhlu lwe-A-type traction frame luqulunqwe ngeentsimbi ezimbini zesikwere, ezinokuqina okulungileyo, ubomi obude benkonzo kunye nezinga eliphantsi lokungaphumeleli.Intloko yebhola inokulungelelanisa i-gap (i-gasket yokulungelelanisa) ngokwemeko yokugqoka, ukunciphisa iindleko zokugcinwa komsebenzisi.Intloko yebhola edityanisiweyo ilungiswe ngeebholiti ukuze kube lula ukutshintshwa.

6. Isakhiwo sebhokisi isakhelo sangaphambili

Uyilo lwesakhiwo sebhokisi kunye ne-flange igcina indawo yoxinzelelo oluphezulu kude ne-weld seam, ephucula ukuthembeka kunye nokuqina kunye nokwandisa ubomi benkonzo yecandelo lezakhiwo.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. Uyilo olunengqiqo

Ukufumana ilifa leCaterpillar ekhokelayo kwishishini-uyilo lokuvuya olusemgangathweni, uhambo olufutshane kunye nolawulo olubekwe kakuhle luvumela umqhubi ukuba asebenzise imivumbo emininzi ngesandla esinye.Amandla okulawula ukukhanya anciphisa ukudinwa komqhubi.

8. Ikhebhu ebanzi kwaye ekhululekile

I-cab ibekwe kwisakhelo sangaphambili, kwaye indawo yesakhelo sokutsalwa, i-turntable kunye ne-blade ingabonakala ngokucacileyo, eluncedo 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.
