Chiyambi cha Zamalonda

SEM921 self-propelled motor grader ili ndi pampu yotulutsa ya Rexroth variable monga muyezo, yomwe imagawira kutuluka pakufunika ndikupulumutsa mphamvu;Chiyerekezo chapadera cha Caterpillar komanso valavu yowongolera chipukuta misozi (PPPC) imapangitsa kuti makinawo azigwira bwino ntchito ndikuwongolera magwiridwe antchito a makinawo.magwiridwe antchito ndi magwiridwe antchito.

Zogulitsa Zamalonda

1. The SEM921 motor grader imatenga kachipangizo kakang'ono ka hydraulic kamene kamakhala koyambirira komanso kulipidwa molingana, komwe kumapereka zolosera komanso zolondola kuyenda kwa zida, kumapangitsa kuti ntchitoyo ikhale yabwino komanso magwiridwe antchito, ndipo chimango chimatengera mawonekedwe owoneka ngati bokosi okhala ndi flanges, ndi Caterpillar self. -made Mtsuko wam'mbuyo umatsimikizira kuti makinawo ndi amphamvu komanso okhazikika, kabati ndi yayitali komanso yayikulu, ndipo mpweya wokhazikika umakhala womasuka;mphamvu yochepetsera m'munsi ndi sitiroko zimachepetsa kutopa kwa oyendetsa.

2. Msempha wakumbuyo wodzipangira wokha wa Caterpillar umathandizira kunyamula, kugawa katundu moyenera, ndikusintha moyo;mabuleki a caliper disc amathandizira magwiridwe antchito ndi 20% ndipo ndi odalirika;magiya anayi a mapulaneti amakonzekera kuyendetsa komaliza, komwe kumakhala ndi mphamvu yonyamula mphamvu;mabuleki kunja, kukonza Yabwino;palibe jekeseni wamafuta wofunikira, kupulumutsa nthawi, ntchito ndi ndalama.

3. Ma electro-hydraulic oyendetsedwa ndi mabowo asanu ndi awiri amatha kumaliza kusinthana kwa dzenje mu kabati.Kugwiritsa ntchito pobowo koyenera kumapangitsa kuti tsambalo lifike pansi pa dzenje pochotsa zomera zomwe zamera mu dzenjelo.Kupyolera mu kusintha kwa dzenje malo a ndodo yolumikizira, ngodya pakati pa tsamba ndi nthaka ikhoza kusinthidwa bwino, yomwe ndi yabwino kukonzanso ngalande ndi malo otsetsereka a mtsinjewo.Ikayikidwa kumapeto kwa dzenje, tsambalo limatha kufika madigiri 90 perpendicular pansi, lomwe ndi losavuta kugwira ntchito zotsetsereka kumbuyo.Ma bushings osinthika ndi okhazikika mu ndodo yolumikizira kuti akonzere mosavuta ndikukonza, kuchepetsa nthawi yautumiki ndi mtengo wokonza.

4. Ntchito yoyandama ya tsamba ili ndi zida zokhazikika, zomwe zimachepetsa zovuta zantchito ndikuwongolera magwiridwe antchito.Pamene ma cylinders apawiri amafuta akuyandama nthawi imodzi, tsambalo limadalira mphamvu yake yokoka kuti imamatire pansi ndikusunthira mmwamba ndi pansi ndikutulutsa pansi kuti muteteze msewu wovuta.Amagwiritsidwa ntchito pochotsa chipale chofewa komanso kuchotsa zinyalala zam'misewu.Silinda imodzi yonyamulira imayandama, yomwe imatha kupanga mbali imodzi ya tsamba pafupi ndi malo ogwirira ntchito molimbika, ndipo mbali ina ya silinda yokweza imagwiritsidwa ntchito kuwongolera kutengera kwa tsamba.

5. PPPC (Proportion Priority, Pressure Compensation) valve control valve yopangidwa mwapadera ndi Caterpillar kwa oyendetsa galimoto amagawa mphamvu molingana ndi kufunikira ndi kuyenda molingana ndi chiwerengero, kuonetsetsa kuti dalaivala akhoza kugwiritsa ntchito makina kuti akwaniritse zochita zambiri zamagulu ndikusintha kwambiri ntchito yabwino.The variable displacement plunger pump imagwiritsidwa ntchito kuchepetsa kutayika kwa mphamvu, kuchepetsa kutentha kopangidwa ndi ma hydraulic system, ndikuchepetsa kugwiritsa ntchito mafuta.Ma hydraulic ozindikira katundu amapereka mayendedwe odziwikiratu, olondola ogwiritsira ntchito kuti ntchito ikhale yabwino komanso yogwira ntchito.Valve ya PPPC imakhala ndi valavu yotsekera yotsekera kuti iteteze kutulutsa kwamkati kwa valavu, kusunga malo a chida cha makina pamene palibe ntchito ya hydraulic, ndikuonetsetsa kuti ntchitoyo ndi yabwino;kupewa kuyenda mwangozi kwa chida cha makina ndikupewa kuvulala mwangozi kwa ogwira ntchito.

6. Chojambula chopangidwa ndi bokosi chokhala ndi flange chimasunga malo opanikizika kwambiri kutali ndi seam weld, zomwe zimapangitsa kuti zikhale zodalirika komanso zokhazikika komanso zimatalikitsa moyo wautumiki wa zigawo zamapangidwe.Mapangidwe a mbale yopitilira pamwamba ndi pansi amapereka mphamvu zabwino zokhazikika ndipo amagwirizana kwathunthu ndi zofunikira za kapangidwe ka zigawo za Caterpillar, zomwe zimatha kutalikitsa moyo wa chimango chakutsogolo ndikuchepetsa mtengo wogwiritsa ntchito.Mapaipi amakonzedwa pambali ya chimango chakutsogolo kuti akonze mosavuta.Zigawo zazikuluzikulu zimagwiritsa ntchito zitsamba zodzipaka mafuta kuti zikhale zodalirika komanso kuchepetsa ndalama zosamalira.

7. Cab ili pa chimango cha kutsogolo, ndipo malo a traction frame, turntable ndi tsamba amatha kuwoneka bwino, zomwe zimathandiza kuti dalaivala aziwongolera bwino malo a tsambalo.Wamtali komanso wotakasuka (1.9 metres m'mwamba), amatha kuyendetsedwa atayimirira, ndipo kuchuluka kwake ndi 30% kukulirapo.Kuwongolera kwa mawilo akutsogolo kumawonekera bwino pamene chiuno chikupindika, kuonetsetsa chitetezo ndi kulondola kwa ntchitoyo.
