Muhurongwa hwemazuva ano hwemaindasitiri, hurongwa hwemahydraulic hunoshandiswa zvakanyanya muminda yakasiyana-siyana yakadai semichina yekuvaka, michina yekuchera migodhi, uye kuvaka ngarava nekuda kwekubatsira kwayo kwekutumira simba zvakanaka uye zvakagadzikana. Vharuvhu yemabhureki, sechikamu chakakosha chehurongwa hwemahydraulic, inonyanya kukosha.
1. Kuve nechokwadi chekuchengetedzwa kwekushanda kwemidziyo
Midziyo inofambiswa ne hydraulic system inowanzova nemitoro yakakura uye kumhanya kwakanyanya. Kana tsaona ikaitika uye braking ikasakwanisa kuitwa nenguva, zvingangokonzera tsaona dzakakomba dzekuchengetedza. Vharuvhu rebhureki rinogona kupa simba rebhureki rakakodzera mumamiriro ekushanda akajairwa, zvichibvumira michina kumira zvakanaka zvichienderana nechinangwa chemushandisi, kudzivirira kusagadzikana kwekumhanya; mumamiriro ezvinhu enjodzi akadai sekukundikana kwemagetsi, nekugadzirisa vharuvhu rebhureki kuenda mberi uye kubatana nezvinhu zvakaita se accumulators, inogona kupindura nekukurumidza uye kuita emergency braking. Semuenzaniso, panguva yekushanda kwemugodhi, michina mikuru yakaita se excavators inoshandisa vharuvhu rebhureki kuti imire nenguva kana ikangoerekana yakundikana, kudzivirira michina kuti isatsvedze kana kurasikirwa nekudzora, uye kuona kuchengetedzeka kwevashandi nezvinhu zvemidziyo.
2. Kuvimbisa kushanda kwakarurama uye kwakasimba
Kushanda kwe hydraulic system kunoda kudzorwa kwakanyatsojeka, uye hunhu hwe brake valve hunokanganisa zvakananga kururama nekugadzikana kwekushanda. Maumbirwo ayo akamanikana anoibvumira kuiswa munzvimbo dzakamanikana pasina kukanganisa marongerwo ese e hydraulic system, uye inogonawo kushanda pamwe chete nezvimwe zvikamu. Uyezve, ine kunzwa kwakanaka kwetsoka, kukurumidza kupindura kwekumanikidzwa, uye kugadziriswa kwakapfava, zvichibvumira vashandisi kudzora simba rekubhureka nemazvo zvichienderana nemamiriro chaiwo ekushanda. Tora crane mumichina yekuvaka semuenzaniso. Munguva yekushanda kwekusimudza, brake valve inogona kumisa ruoko rwekusimudza panzvimbo yakatarwa, ichidzivirira kusagadzikana kwekubhureka kunogona kukonzera kuti chinhu chinorema chizununguke kana kutodonha, zvichivandudza kunaka kwekushanda uye kushanda zvakanaka.
3. Kujairana nenzvimbo dzakasiyana dzebasa nemamiriro ezvinhu
Masisitimu ehydraulic mumaindasitiri akasiyana anotarisana nenzvimbo dzakasiyana dzekushanda nemamiriro ezvinhu. Magadzirirwo ekushanda kwevharuvhu remabhureki anosarudza kuchinjika kwaro. Tafura inotevera inoratidza magadzirirwo akakosha evharuvhu remabhureki uye mamiriro ekugadzirisa anoenderana nawo:
| Rudzi rweParamende | MaParamita Akananga | Mamiriro Ekugadzirisa |
| Kushanda Pakati | Oiri yeHydraulic yakagadzirwa neMineral | Inofukidza masisitimu mazhinji emahydraulic emaindasitiri uye inoenderana zvakanyanya. |
| Nhamba yeViscosity | 2.8 – 380mm²/s | Inogona kushanda zvakadzikama mumamiriro ezvinhu akadai sekunze kunotonhora munzvimbo dzekuchamhembe (zvinodiwa zvishoma zvekusviba) uye munzvimbo dzemaindasitiri dzinopisa zvakanyanya (zvinodiwa zvakanyanya zvekusviba). |
| Tembiricha yemafuta eHydraulic | - 30℃ kusvika 107℃ | Inokwanisa kushanda mumamiriro akasiyana-siyana akaomarara kubva pakutonhora zvakanyanya kusvika pakupisa kwakanyanya. |
| Kudzvanywa Kwekugadzika Range | 20 – 200bar | Inosangana nezvinodiwa zvekubhureka zvemitoro yakasiyana-siyana uye simba, kubva pamidziyo yekubhureka midiki kusvika pakubhureka kwakasimba kwemichina inorema. |
| Kumanikidzwa Kwakanyanya Kwekupinda kweNhevedzano Yese | 210bha | Inopa rutsigiro rwakakwana rwesimba remabhureki kune masisitimu ehydraulic ane zvinodiwa nemhepo ine simba rakawanda. |
4.Simudza kuvimbika uye hupenyu hwebasa rehurongwa
Vharuvhu yemabhureki ine zvinodiwa zvakasimba zvekuchena (zvichisvika padanho re18/16/13, ISO4406), uye zvakare inoganhurira kumanikidzwa kwemafuta ekudzoka zvakanyanya kusapfuura bhaa rimwe. Izvi zvinobatsira kuchengetedza kuchena uye kugadzikana kwehurongwa hwe hydraulic. Nzvimbo yakachena yehurongwa inoderedza kupera kwezvikamu zve hydraulic nekusvibiswa, uye kumanikidzwa kwemafuta ekudzoka kwakasimba kunodzivirira kuvhunduka kwehurongwa kunokonzerwa nekuchinja-chinja kwekumanikidzwa, nokudaro zvichideredza mwero wekukundikana kwehurongwa hwese hwe hydraulic, zvichiwedzera hupenyu hwebasa remuchina, zvichideredza mari yekugadzirisa uye nguva yekushanda, uye kuve nechokwadi chekuti kugadzirwa kunoramba kuripo.
Vharuvhu remabhureki rine basa rakakosha muhurongwa hwemahydraulic maererano nekuchengetedzwa, kudzora mashandiro, kugadzirisa nharaunda, uye kuvimbika kwehurongwa. Chinhu chakakosha chakakosha pakushanda kwakasimba, kwakanaka uye kwakachengeteka kwehurongwa hwemahydraulic. Nekuvandudzwa kuri kuitwa tekinoroji yeindasitiri, zvinodiwa kuti vharuvhu remabhureki rishande zvicharamba zvichiwedzera. Vharuvhu remabhureki richagara richivandudzwa, zvichipa rutsigiro rwakasimba pakugadzirwa kwehurongwa hwemahydraulic.
