Nhanganyaya kune bulldozer kuchengetedza valve1. TsanangudzoBulldozer kuchengetedza vharafu ndeye otomatiki yekuvhura uye yekuvhara yekumanikidza yekudzora vharafu yakaiswa mumakiyi maseketi e hydraulic masisitimu (senge midziyo inoshanda, chidhiraivho, kufamba, nezvimwewo). Kana iyo system yekumanikidza inodarika preset yekuchengetedza kukosha, vheji inovhura otomatiki kuti ibvise kumanikidza; Mushure mokunge dzvinyiriro ichidzokera kune yakajairika, valve yakavharwa kuchengetedza kushandiswa kwemaitiro ekushanda kwemaitiro.2. Kushanda musimbotiNheyo yakakosha yemavharuvhu ekuchengetedza yakavakirwa pa "pressure force balance":Ivhavha inoshongedzerwa nechitubu nevhavha core, uye preload simba rechitubu rinoenderana nekuchengetedzwa kwekuchengetedza (preset kukosha) kweiyo system.Kana iyo system yekumanikidza iri pazasi kukosha kwakachengeteka, iyo yevhavha core inovhara pasi pechiito chesimba rechirimo, uye hydraulic oiri haigone kupfuura, uye iyo yakachengeteka inosundidzira inodarika nepakati, uye iyo yakachengeteka simba inosundidzira inodarika. hydraulic oiri pavharuvhu yepakati ihombe kupfuura simba remuchirimo, uye musimboti wevharuvhu unosundirwa kuvhurika. Chikamu chemafuta e hydraulic chinobudiswa kudzokera kutangi yemafuta kuburikidza nevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha),kukonzera kuti system pressure idere.Kana dzvinyiriro inodonha pazasi kukosha kwakachengeteka,simba rechirimo rinosundidzira simbi yevhavha kuti ivhare zvakare,uye sisitimu inodzokera kune yakajairwa kumanikidzwaIyo bulldozer kuchengetedza vharafu ndiyo musimboti yekuchengetedza mudziyo weiyo hydraulic system,inonyanya kushandiswa kudzivirira kukosha kwehurongwa kubva pakudarika iyo yakatarwa. Kana kudzvanywa kwepakati mukati memidziyo kana pombi inokwira uye ichipfuura chikumbaridzo chakaiswa, vharafu yekudzivirira inovhurika otomatiki kuti ideredze kudzvanya nekuburitsa svikiro kunze kwehurongwa, kudzivirira kukuvara kwemidziyo kana njodzi dzekuchengetedza dzinokonzerwa nekudzvinyirira. Chimiro chayo chinowanzobatanidza zvinhu zvakakosha zvakadai semuviri wevharuvhu, musimboti wevharuvhu, uye chitubu. Iyo yevhavha musimboti inowana kuvhura uye kuvhara kutonga pasi peyero yechirimo simba uye system kudzvanywa, yakafanana ne "spring valve core" yekutyaira musimboti weloader kuchengetedza mavharuvhu.
Kushandiswa kwevharuvhu yekuchengetedza yebulldozer
Iyo hydraulic system yebulldozer ndiyo "power centre" yekushanda kwayo uye kufamba, kuvhara zvishandiso zvekushanda (bulldozer, bulldozer), steering system, kufamba hurongwa, etc. Mavharuvhu ekuchengetedza anoita basa rinokosha rekudzivirira mumasitimu aya:
1. Kushanda mudziyo hydraulic system (musimboti application mamiriro)
Bulldozer's bulldozer blade (kusimudza, kutenderedza) uye kusunungura mudziyo (kusimudza, kupinda muvhu) vanotsamira pamasilinda ehydraulic kutyaira, uye panguva yekushanda, mitoro inoerekana (yakadai sebulldozer blade inosangana nematombo akaomarara kana mudziyo wekusunungura uchinamirwa) inogona kukonzera kamwe kamwe kuwedzera cylinder mukati mekumanikidza.
Ivhavhavha yekudzivirira inoiswa muoiri inlet circuit yeoiri cylinder. Kana dzvinyiriro ichipfuura kukosha kwekuchengetedza (kazhinji 1.1 - 1.2 nguva yakatemerwa kumanikidzwa kwegadziriro), valve inovhura kuti ibudise mamwe mafuta e-high-pressure kumashure kwetangi remafuta, kudzivisa deformation kana kuputika kwecylinder barrel uye piston tsvimbo nekuda kwekuremerwa, uye kudzivirira iyo hydraulic pump iyo inotyaira kuvharidzira cylinder yemafuta.
Steering hydraulic system
Bulldozer steering inotsamira pama hydraulic cylinders (kana hydraulic motors) kutyaira kusiyanisa kumhanya kwematinji. Kana manjanji akangoerekana avharika panguva yekufambisa (sekunamira mumadhaka kana kudhumhana nezvipingamupinyi), kudzvanywa mudhiraivha yeoiri yekufambisa kuchawedzera ipapo ipapo.
Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha ku vhuya ku tlula ku tlula ku tlula ku tlula ku tlula,kuviisa silinda ye fambisa,pombi ye tsinga, kana vheji ye tsinga ku tjita ku tlula ku tjita, ku va vekeke ku tlula ku tlula ku tlula ku tlula ku tlula tlula,na ku tjita ku tjita ku txi hambana ni ku tjita ku tlula ku tlula ku tlula ku va txi xiya.
. Kufamba hydraulic system
Mamwe mabulldozer anoshandisa hydraulic drive pakufamba (senge yakazara hydraulic bulldozers), uye mota inofamba inotyaira track kuti itenderere kuburikidza nehydraulic mafuta. Kana iyo nzira yakanamirwa nematombo kana mutoro wakakura zvakanyanya pakukwira, kudzvanywa kwemafuta ekufamba kunowedzera zvisina kujairika.
Vhuru yekudzivirira yedunhu rekufamba yavhurwa kuti isunungure kudzvanywa, kudzivirira mota inofamba, hydraulic pombi, uye yakakwirira-pipeline inotsikirira kudzivirira kuparuka kwegiya remota, kuputika kwepombi, uye kumwe kukanganisa kunokonzerwa nekuremedza. Iyo General Industrial Value yeKuchengetedza Mavharuvhu
Mavharuvhu ekuchengetedza anoshandiswa zvakanyanya muminda yakadai semaboilers, midziyo yekumanikidza, masisitimu eutsi, nezvimwewo, semuenzaniso:
Steam system: yakaiswa pasi pemvura yekudzikisira mavharuvhu, matangi emwenje, midziyo yekuchengetedza kupisa, uye zvimwe midziyo kudzivirira kuputika kunokonzerwa nekudzvinyirira.
Indasitiri yakakosha: Iyo yekupisa yekupisa mafuta bhailer inotora A40 mhando yekuchengetedza vharafu kubata neyakakura tembiricha oiri uye gasi pamusoro pe350 dhigirii, uye iyo mhepo compressor inodzivirira kuchengetedzeka kwetangi yekuunganidza gasi kuburikidza nevhavhavhavhavha. Iyo yakakosha dhizaini ye "otomatiki overpressure zororo kudzoreredza kuvharika" ivimbiso yepasirese yekushanda kwakachengeteka kwemaindasitiri masisitimu.
Iyo bulldozer kuchengetedza vharafu ndiyo "yekuchengetedza kuchengetedza" kweiyo hydraulic system, iyo inodzivirira kuwandisa nekudzora nemazvo kumanikidza. Chishandiso chayo chinomhanya kuburikidza nepakati masisitimu senge chishandiso chinoshanda, chidhiraivho, uye kufamba, uye chinhu chakakosha kuti ive nechokwadi chekushanda uye kwakachengeteka kushanda kwemabulldozer. Mukushandiswa kunoshanda, zvinodikanwa kugara uchitarisa kudzvanywa kwekuisa uye kuvharirwa kwevhavhavhavha yekuchengetedza kuti ive nechokwadi chekunzwa kwayo uye kuvimbika.
