Zogwiritsidwa Ntchito Magalimoto Amtundu wa SEM919 Zogulitsa

Chiyambi cha Zamalonda

SEM919 ndi makina opangira ma mota a Caterpillar's Shangong Machinery.Ndi mtundu wa makina oyendetsa nthaka.Itha kugwiritsidwa ntchito pomanga misewu, yomanga m'matauni, komanso kukonza njira zina komanso kuchotsa matalala.Ngati muwonjezera Ndi kuwonjezera kwa ripper kumbuyo kwa tsamba la dozer, ntchito yochuluka ikhoza kuchitidwa.

Zogulitsa Zamalonda

1. Mbozi zopanga tokha nkhwangwa yakumbuyo

Kupititsa patsogolo kamangidwe kazonyamula, kugawa katundu moyenera, ndi moyo wautali;mabuleki a caliper disc, magwiridwe antchito amakula ndi 20%, odalirika;makonzedwe a zida za mapulaneti anayi oyendetsa komaliza, mphamvu zonyamula katundu zamphamvu;mabuleki akunja, kukonza kosavuta;palibe zofunika jekeseni mafuta, kupulumutsa Nthawi, khama ndi ndalama zapulumutsidwa.

2. Njira yolumikizira ndodo yamabowo asanu ndi awiri (posankha)

Njira yolumikizira mabowo asanu ndi awiri yomwe imayendetsedwa ndi electro-hydraulic imatha kusintha malo a dzenje mu cab;kugwiritsa ntchito dzenje loyenera kungathe kuwonetsetsa kuti tsamba limatha kukhudza pansi pa dzenje pochotsa zomera zomwe zakula mu dzenje;The kusintha kwa ndodo dzenje udindo akhoza bwino kusintha ngodya pakati pa tsamba ndi pansi, amene ndi yabwino kwa kukonza ngalande ngalande ndi otsetsereka kumbuyo kwa mtsinje mtsinje.Ikayikidwa kumapeto kwa dzenje, tsambalo limatha kufika madigiri 90 perpendicular pansi, lomwe ndi losavuta kugwira ntchito zotsetsereka zam'mbuyo;ma bushings osinthika okhazikika pamabowo olumikizira ndodo ndi yabwino kukonza ndi kukonza, ndipo amatha kuchepetsa nthawi yautumiki ndi ndalama zosamalira.

3. Tsamba loyandama ntchito

Ntchito yoyandama yamtundu wokhazikika imachepetsa kuvutikira kwa ntchito 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.

4. Katundu sensing hydraulic system

PPPC (Proportion Priority, Pressure Compensation) valve control valve yopangidwa mwapadera ndi Caterpillar for motor graders imagawa mphamvu molingana ndi kufunikira ndikuyenda molingana ndi gawo, kuwonetsetsa kuti dalaivala amatha kugwiritsa ntchito makinawo kuti amalize kuchitapo kanthu pawiri komanso kukonza bwino ntchito.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.

5. Lembani drawbar A

Chojambula chamtundu wa A chimapangidwa ndi zitsulo ziwiri zazikulu, zomwe zimakhala zolimba, moyo wautali wautumiki komanso kulephera kochepa.Mutu wa mpira ukhoza kusintha kusiyana (kusintha gasket) molingana ndi momwe amavalira, kuchepetsa mtengo wokonza wogwiritsa ntchito.Mutu wa mpira wolumikizidwa womwe umalumikizidwa umakhazikika ndi mabawuti kuti usinthe mosavuta.

6. Bokosi dongosolo kutsogolo chimango

Mapangidwe amtundu wa bokosi ndi flange amasunga malo opanikizika kwambiri kutali ndi seam weld, zomwe zimapangitsa kuti zikhale zodalirika komanso zolimba komanso zimatalikitsa moyo wautumiki wa zigawo zomanga.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. Kukonzekera koyenera

Cholowa cha Caterpillar chotsogola chodziwika bwino cha zokometsera, kuyenda kwakanthawi kochepa komanso zowongolera zokhala bwino zimalola wogwiritsa ntchito kuyitanitsa zokometsera zingapo ndi dzanja limodzi.Mphamvu yowongolera kuwala imachepetsa kutopa kwa oyendetsa.

8. Cab yotakata komanso yabwino

Cab ili pa chimango chakutsogolo, ndipo malo a traction frame, turntable ndi tsamba amatha kuwoneka bwino, zomwe zimathandiza kuti dalaivala azitha kuyang'anira 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.
