45# ipayipi lensimbi lisezingeni eliphezulu futhi intengo ephansi
Ishubhu lensimbi elingenamthungo liwumugqa omude wensimbi onengxenye engenalutho futhi alikho ilunga elizungezile. Ipayipi lensimbi elingenamthungo linengxenye engenalutho futhi lingasetshenziswa njengepayipi lokudlulisa uketshezi, njengepayipi lokuhambisa uwoyela, igesi yemvelo, igesi, amanzi nezinye izinto eziqinile. Uma kuqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi lensimbi engenamthungo linamandla afanayo aguquguqukayo kanye ne-torsional kanye nesisindo esincane. Kuyinsimbi yesigaba sezomnotho. Isetshenziswa kakhulu ekwenzeni izingxenye zesakhiwo kanye nezingxenye zemishini, njengepayipi lokubhoboza uwoyela, umshini wokuhambisa imoto, uhlaka lwamabhayisikili kanye nesikafula sensimbi esisetshenziswa ekwakheni. Ukukhiqiza izingxenye zendandatho ngepayipi lensimbi elingenamthungo kungathuthukisa ukusetshenziswa kwezinto, kube lula inqubo yokukhiqiza, konga izinto zokusebenza namahora okucubungula, njengeringi elithwele, umkhono kajack, njll. Ipayipi lensimbi lisetshenziswa kabanzi ekukhiqizeni. Ipayipi lensimbi liphinde libe yinto esemqoka yazo zonke izinhlobo zezikhali ezijwayelekile. Isibhamu kanye nomgqomo kufanele kwenziwe ngepayipi lensimbi. Ipayipi lensimbi lingahlukaniswa libe yipayipi eliyindilinga kanye nepayipi elimise okukhethekile ngokuya ngendawo ehlukene ye-cross-sectional kanye nokuma. Ngenxa yokuthi indawo eyindilinga inkulu kakhulu ngaphansi kwesimo somjikelezo olinganayo, uketshezi oluningi lungathuthwa ngepayipi eliyindilinga. Ukwengeza, lapho isigaba sendandatho singaphansi kokucindezela kwe-radial yangaphakathi noma yangaphandle, amandla afana kakhulu. Ngakho-ke, amapayipi amaningi ensimbi angamapayipi ayindilinga. Nokho, ipayipi eliyindilinga nalo linemikhawulo ethile. Isibonelo, ngaphansi kwesimo sokugoba indiza, amandla okugoba wepayipi eliyindilinga awanamandla njengalawo wesikwele kanye nepayipi elingunxande. Amapayipi ayisikwele nawonxande avame ukusetshenziswa ohlakeni lwemishini ethile yezolimo namathuluzi nefenisha yensimbi neyokhuni. Amapayipi ensimbi anobunjwa obukhethekile obunye ubujamo besigaba nawo ayadingeka ngokwezinjongo ezahlukene.
