I-center pivot sprinkler (ngezinye izikhathi ibizwa ngokuthi i-central pivot irrigation), ebuye ibizwe ngokuthi isifafaza esiyindilinga sikagesi, isifafaza sohlobo lwe-pointer njll., kuyindlela yokunisela ngezitshalo lapho okokusebenza kuzungeza i-pivot futhi izitshalo ziniselwa ngezifafazi.Amasistimu okunisela e-centre-pivot anenzuzo ngenxa yekhono lawo lokusebenzisa amanzi ngendlela efanele kanye nokwandisa isivuno sepulazi.Amasistimu asebenza kahle kakhulu ezindaweni ezinkulu zomhlaba.
Isivuno esifanelekiles: i-alfalfa, ummbila, ukolweni, amazambane, isithombo sebhitrudi, okusanhlamvu nezinye izitshalo zemali.
Ingxenye ephakathi esekela isiphetho se-sprinkler ilungisiwe, futhi okunye okunye okufafaza kuhamba eduze kokuphela okungashintshi okushayelwa injini.Ngokusebenzisa isixhumi esibonakalayo ekupheleni kwe-Central Branch shaft, amanzi ampontshelwa phezulu emfuleni noma emthonjeni futhi athunyelwe epayipini lamanzi ku-sprinkler truss, abese ethunyelwa ensimini ngokusebenzisa isifafazi ukuze kutholakale ukuchelela okuzenzakalelayo.
Indawo eyisiyingi egxile ku-pivot iyaniselwa, ivamise ukudala iphethini eyindilinga ezitshalweni uma ibhekwa phezulu.
Ukuchelela nge-center-pivot kusebenzisa inani elincane kunezinye izindlela zokunisela ngaphezulu, njengokunisela ngemisele.
Iphinde ibe nezindleko eziphansi zabasebenzi kunamasu okuchelela phansi adinga ukumbiwa kwamashaneli.
Futhi, ukuchelela kwe-centre-pivot kunganciphisa inani lokulinywa komhlabathi.
Kuyasiza ekunciphiseni ukugeleza kwamanzi kanye nokuguguleka komhlabathi okungenzeka ngokuchelela komhlabathi.
Ukulinywa kancane kuphinde kukhuthaze izinto eziningi eziphilayo nezinsalela zezitshalo ukuthi zibole zibuyele emhlabathini.Kuphinde kunciphise ukucinana kwenhlabathi.
Ama-pivots amaphakathi ngokuvamile angaphansi kwamamitha angu-500 (1,600 ft) ubude (irediyasi eyindilinga) kanti usayizi ovame kakhulu umshini ojwayelekile wamamitha angu-400 (1⁄4 mi), ohlanganisa cishe amahektha angama-50 (amahektha angu-125) omhlaba.

Ukusebenzisa ikhwalithi efanayo ye-UMC VODAR motor, ukuzivumelanisa kwayo nemvelo, ukubanda okukhulu nokushisa akuthinteki, izinga lokuhluleka eliphansi, izinga eliphansi lokugcinwa, liphephile futhi linokwethenjelwa.
Ngomsebenzi wokuvikela, ngenxa yokungazinzi kwe-voltage kanye nesimo sokugcwala ngokweqile, ngeke kuvele i-fuse, into ephukile yocingo.
Ukusebenzisa igobolondo le-aluminium ingxubevange, kungavala kahle ukungena kwamanzi.
Injini ivalwe kahle, akukho ukuvuza kwamafutha, impilo ende yesevisi.
Yamukela ikhwalithi efanayo ye-VODAR reducer ye-UMC, efanele izimo zensimu ezehlukene, ephephile futhi enokwethenjelwa.
Uhlobo lwebhokisi lokufakwayo kanye ne-output oil seal, kuvimbela ngempumelelo ukuvuza kwamafutha.
Isivikelo sangaphandle sokuvikela uthuli kukho kokubili amashafu okokufaka nokuphumayo.
Igumbi lokunweba eligcwele lensimbi engenasici, kusetshenziswa uwoyela wegiya elicindezela kakhulu, ukusebenza kokuvikela ukugcotshwa kwegiya lezikelemu kuyamangaza.
Ukuxhumana okuphambene nomzimba kusebenzisa indlela yokuxhuma ibhola kanye ne-cavity, futhi amashubhu ebhola ne-cavity axhunywe ngamasilinda erabha, anokuguquguquka okuqinile kwendawo futhi athuthukisa kakhulu ikhono lokukhuphuka.
Ikhanda lebhola lishiselwe ngokuqondile epayipini lomzimba elifushane, elikhulisa kakhulu amandla futhi likwazi ukubhekana namandla aqinile ensimbi ezimweni zezulu ezibandayo futhi igweme ukuwa kwemishini.
