A uhlelo lwe-hydraulicisebenzisa uketshezi olucindezelwe ukudlulisa amandla nokwenza umsebenzi wemishini. Iguqula amandla emishini ibe amandla aketshezi, bese ibuyela ekuhambeni. Onjiniyela bathembele ezimisweni ezifana nezibalo ze-Navier-Stokes kanye nefomula ye-Darcy-Weisbach ukuze bathuthukiseukwakhiwa kwesistimu ye-hydraulic, njengoba kuboniswe kunoma iyiphi imininingwaneumdwebo wesistimu ye-hydraulic.
Okuthathwayo Okubalulekile
- Amasistimu we-hydraulic asebenzisa uketshezi olucindezelwe ukuze aphindaphinde amandla futhi enze imisebenzi esindayo ngokulawula okunembayo, ngokusekelwe kuMthetho kaPascal.
- Izingxenye ezibalulekile zihlanganisaamaphampu, amachibi, ama-valve, ama-actuator, noketshezi, ngakunye kubalulekile ekudluliselweni nasekulawuleni amandla ngendlela efanele.
- Amasistimu we-hydraulic anika amandla izimboni eziningi ngokunikeza amandla aphezulu, ukusebenza kahle kwamandla, nokuthembeka, kodwa adinga ukulungiswa njalo ukuze agweme ukuvuza nokungcola.
Indlela IHydraulic System esebenza ngayo
Izimiso Eziyisisekelo Zohlelo Lwamanzi (Umthetho KaPascal)
Isistimu ye-hydraulic isebenza ngokususelwe kuMthetho kaPascal, umgomo oyisisekelo kumakhenika oketshezi. Umthetho kaPascal uthi lapho ukucindezela kusetshenziswa oketshezini oluvalekile, ukucindezela kudluliselwa ngokulinganayo kuzo zonke izinhlangothi kulo lonke uketshezi. Lo mgomo uvumela amasistimu we-hydraulic ukuthi aphindaphinde amandla futhi enze ukuphakamisa okusindayo ngokufaka okuncane.
Ngokwesibonelo, lapho umuntu efaka amandla ku-piston encane, ukucindezela okukhiqizwa oketshezini kuhamba ngamapayipi namapayipi kuye ku-piston enkulu. I-piston enkulu, enendawo enkulu, ikhiqiza amandla amakhulu kakhulu okukhipha. Ubudlelwano phakathi kwamandla okufaka namandla okukhiphayo kuncike esilinganisweni sezindawo zepiston. Uma i-piston yokufaka inendawo engamasentimitha-skwele angu-2 futhi i-piston ephumayo inendawo yamasentimitha-skwele angu-20, amandla okukhiphayo azoba mkhulu ngokuphindwe kashumi kunamandla okufaka, kucatshangwa ukuthi ingcindezi efanayo isetshenziswa.
Umthetho kaPascal uvumela amasistimu asebenzisa amanzi ukuba asebenzise amapayipi neziqukathi zomumo ohlukahlukene ngaphandle kokulahlekelwa ingcindezi, okuwenza akwazi ukuzivumelanisa nezimo ezisetshenziswayo ezihlukene zemishini.
Lesi simiso sakha isisekelo semishini efana nemishini yokunyathelisa esebenzisa amanzi, amabhuleki ezimoto, nemishini yokwakha. Amandla okudlulisa ingcindezi ngendlela efanayo avumela onjiniyela ukuthi bakhe amasistimu angaphakamisa izimoto, asebenzise imishini esindayo, futhi anikeze ukulawula okunembayo kuzilungiselelo zezimboni.
Ukusebenza Kwesinyathelo Ngesinyathelo Kwesistimu Yamanzi
Ukusebenza kwesistimu ye-hydraulic kuhilela izinyathelo ezimbalwa ezibalulekile, ngasinye sinomthelela ekudluliselweni okuphumelelayo nasekulawuleni amandla. Ukulandelana okulandelayo kuveza inqubo ejwayelekile:
- Okokufaka Amandla: Uhlelo luqala ngokufaka okomshini, okufana nemoto kagesi noma injini, eshayela aiphampu ye-hydraulic.
- I-Fluid Pressurization: Iphampu idonsa uketshezi olunamanzi amaningi echibini bese ilicindezela, idale ukugeleza koketshezi ngaphansi kwengcindezi ephezulu.
- Ukudluliswa Kwengcindezi: Uketshezi olunomfutho luhamba ngamapayipi namapayipi luye ezingxenyeni ezihlukahlukene, njengama-valve nama-actuator.
- Control and Direction: Amavaluvu alawula indlela, ingcindezi, nezinga lokugeleza koketshezi, okuvumela ukulawula okunembe ekuhambeni kwama-actuator.
- Okukhiphayo Kwemishini: Ama-Actuator, njengamasilinda nomaama-hydraulic motors, guqula amandla oketshezi abuyele ekusebenzeni komshini, ukwenza imisebenzi efana nokuphakamisa, ukusunduza, noma ukuzungezisa.
- Buyisa Ukugeleza: Ngemva kokuqeda umsebenzi walo, uketshezi lubuyela endaweni yokugcina amanzi, lulungele ukuhanjiswa kabusha ngepompo.
Ochwepheshe bavame ukusebenzisa amathuluzi okuxilonga, okuhlanganisa izikali zokucindezela kanye nama-multimeters edijithali, ukuqapha imingcele yesistimu efana namazinga okucindezela nezici zikagesi. Uma izilinganiso zibonisa ukungahambi kahle, zingahlola izingxenye zangaphakathi ukuze ziguge noma zilimale. Le ndlela ihlanganisa idatha yobuningi nokuhlola okubukwayo ukuze kuqinisekiswe ukusebenza kwesistimu okuphelele.
Ucwaningo lokuhlola lubonise ukuthi amasistimu asebenza ngamanzi angakwazi ukuzuza ukonga amandla okubalulekile kanye nokusebenza kahle okuthuthukisiwe ngobuchwepheshe bokulawula obuthuthukisiwe. Isibonelo, amasekhethi asebenzisa amavalvu okulawula ukugeleza anganciphisa ukusetshenziswa kwamandla ngaphezu kuka-15% ngaphandle komthwalo futhi acishe abe ngu-10% emithwalweni ephezulu. Izilinganiso zokushisa ziphinde zembula ukuthi amasistimu asebenza kahle asebenza emazingeni okushisa aphansi, athuthukisa ukusimama futhi anciphise ukuguga.
Amazinga emboni, njenge-ISO 4409:2007, ahlinzeka ngemihlahlandlela yokuhlola kanye nokuqinisekisa ukusebenza kahle kwamaphampu namamotho asebenza ngogesi. Lawa mazinga aqinisekisa ukuthi abakhiqizi nonjiniyela bangathembela kudatha enembile, ephindaphindwayo lapho bekhetha futhi begcina izingxenye zesistimu.
Qaphela: Ukuqonda ukusebenza kwesinyathelo nesinyathelo kanye nemithetho eyisisekelo yohlelo olusebenza ngamanzi kusiza onjiniyela baklame imishini ethembekile nesebenza kahle yezinhlelo eziningi ezahlukene.
Izingxenye Eziyinhloko Zohlelo Lwe-Hydraulic
Uhlelo lwe-hydraulic luncike ezingxenyeni ezimbalwa ezibalulekile, ngayinye idlala indima ethile ekudluliselweni kwamandla nasekulawuleni. Ukuqonda lezi zingxenye kusiza onjiniyela baklame imishini ephumelelayo nethembekile.
Iphampu yeHydraulic
Iiphampu ye-hydrauliciguqula amandla emishini abe amandla asebenza ngamanzi, enze ukugeleza koketshezi olucindezelwe olunika amandla uhlelo. Izinhlobo zamaphampu ezivamile zifaka amaphampu egiya, i-vane, nama-axial piston. Amaphampu esimanje anikeza ukusebenza kahle okuphezulu, namanye amamodeli athola ukusebenza kahle okungaphezulu kuka-92% kanye nezingcindezi zokusebenza ezifika kubha engu-420 (6090 psi). Izilawuli ze-elekthronikhi ezithuthukisiwe zivumela ukulungiswa okunembile kokugeleza nokucindezela, okwenza lawa maphampu afanelekele izinhlelo zokusebenza ezifunwa yizimboni neselula.

Amavalvu
Amavalvu alawula indlela, ingcindezi, kanye nezinga lokugeleza koketshezi olusebenza ngamanzi. Izinhlobo zifaka ama-valve okucindezela, aqondisayo, nawokugeleza. Onjiniyela basebenzisa izindlela zobuningi ezifana nokuhlolwa kwe-stroke ingxenye kanye nokuhlolwa kobufakazi be-in-situ ukuze baqinisekise ukwethembeka nokuphepha kwe-valve. Izindinganiso zesimanje, njenge-ANSI/ISA-96.06.01-2022, zichaza indlela yokusebenza yama-actuator amavalvu, okuhlanganisa ukuxilonga nokuphepha.
Ama-Actuator (Amasilinda namaMotho)
Ama-Actuator aguqula amandla kagesi abe ukunyakaza komshini. Amasilinda angamaHydraulic akhiqiza ukunyakaza okuqondile, ngenkathiama-hydraulic motorsdala ukunyakaza kwe-rotary. Lezi zingxenye ziletha imiphumela yamandla aphezulu, amanye amasilinda akhiqiza kufika ku-43,000 lbf. Ama-electro-hydraulic actuators athuthukisa ukusebenza kahle futhi anganciphisa ukusetshenziswa kwamandla ngaphezu kuka-50% ngokuvuselela amandla.
I-Hydraulic Fluid
I-hydraulic fluid idlulisa amandla, igcoba izingxenye, futhi isuse ukushisa. I-viscosity yoketshezi ithinta ukusebenza kahle, ukuthambisa, nokukhiqiza ukushisa. Onjiniyela bakhetha uketshezi ngokusekelwe ezidingweni zesistimu, izinga lokushisa, kanye nohlobo lwephampu. Izithasiselo ezifana nama-anti-wear agent nama-rust inhibitors zivikela izingxenye zesistimu futhi zandise ukuphila koketshezi. Ukukhetha kahle uketshezi kuqinisekisa ukusebenza kahle nokuthembeka kwanoma yiluphi uhlelo lwe-hydraulic.
Izicelo Zesistimu Ye-Hydraulic, Izinzuzo, Nokuqhathanisa
Izicelo Ezivamile Zohlelo Lwe-Hydraulic
Amasistimu we-hydraulic anika amandla izimboni eziningi. Ezokwakha, ezolimo, i-aerospace, izimoto, nokuphathwa kwezinto ezibonakalayo konke kuncike kulawa masistimu ukuze aphakamise izinto ezisindayo nokulawula okunembayo. Isibonelo, i-Pennar Industries ihlela ukukhiqiza amasilinda angama-hydraulic angu-150,000 ngonyaka ngezolimo nokwakha. Iphrojekthi yokuchelela ye-Polavaram isebenzisa amasilinda angama-hydraulic angu-96 ukusebenzisa amasango angama-48 emisebe. Ithebula elingezansi ligqamisa isikali nokuhlukahluka kwezinhlelo zokusebenza:
