Isingeniso
Kungqalasizinda yesimanje yezimboni, ukuthuthwa kwamanzi kungenye yezinhlelo zobunjiniyela ezibaluleke kakhulu. Ukusuka ekuhanjisweni kukawoyela ongahluziwe kanye nokucutshungulwa kwamakhemikhali kuya ekuhanjisweni kwamanzi kamasipala kanye nokuthutha udaka lwezimayini, izimboni zithembele ezinhlelweni zokumpompa ezizinzile nezisebenzayo ukuze zihambise uketshezi ebangeni elifushane nelide. Enkabeni yalawa masistimu kukhona i-Pipeline Pump, idivayisi eyimishini engukhiye edizayinelwe ukudluliswa koketshezi oluqhubekayo{2}}lokusebenza ngempumelelo ngamapayipi.
Iphampu Yephayiphi akuyona nje iyunithi yemishini elula. Kuwuhlelo olunobunjiniyela oluhlanganisa ama-hydraulics, ukwakheka kwemishini, nobuchwepheshe bokulawula ukuze kuqinisekiswe ukugeleza okuzinzile, ibhalansi yengcindezi, nokusebenza kahle kwamandla. Ukuqonda ukuthi i-Pipeline Pump isebenza kanjani kubalulekile konjiniyela, abaklami besistimu, o-opharetha, namathimba okuthenga ngenxa yokuthi ukusebenza kwepompo kuthinta ngokuqondile ukuphepha kwesistimu, izindleko zokusebenza, nokuthembeka{2}}kwesikhathi eside.
Lo mhlahlandlela wobunjiniyela unikeza incazelo ejulile yezobuchwepheshe yesimiso sokusebenza sePump Pipeline. Ihlanganisa isakhiwo sangaphakathi, izindlela zokuguqula amandla, ukuziphatha kwe-hydraulic, izinhlobo ezahlukene zokusebenza, nokucatshangelwa okubalulekile komklamo wobunjiniyela. Umgomo uwukusiza abafundi ukuthi baqonde hhayi kuphela ukuthi Iphampu Yephayiphi isebenza kanjani, kodwa nokuthi kungani umklamo wayo ubalulekile ezinhlelweni zangempela zezimboni.
1. Isakhiwo Esiyisisekelo Sephampu Yepayipi
Ukuze uqonde isimiso sokusebenza sePumpu Yephayiphi, kuyadingeka ukuthi uqale uqonde ukwakheka kwayo komzimba. Zonke izici zokusebenza zephampu zisuka ekwakhiweni kwayo komshini.
• 1.1 Izingxenye Eziyinhloko Zephampu Yephayiphi
Iphampu yepayipi evamile iqukethe izingxenye ezimbalwa ezibalulekile:
I-Pump Casing (i-Volute noma i-Diffuser Housing)
I-casing igobolondo langaphandle eliqukethe uketshezi futhi liqondise ukugeleza kwalo. Iklanyelwe ukumelana nokucindezela kwangaphakathi okukhiqizwa ngesikhathi sokusebenza. Kumasistimu wePump Pipeline centrifugal, i-casing iguqula amandla esivinini abe amandla okucindezela.
I-Impeller noma i-Displacement Mechanism
