Zisho Ukuthini Izilinganiso Ze-NEMA?

I-NEMA 1:Izivalo ze-NEMA 1 zenzelwe ukusetshenziswa endlini futhi zinikeza isivikelo ekuthinteni abantu ngezingxenye zikagesi ezishajwa bukhoma.Iphinde ivikele okokusebenza emfucumfucwini ewayo (ukungcola).

I-NEMA 2:Indawo ebiyelwe ye-NEMA 2, yazo zonke izinhloso nezinjongo, iyafana nendawo ebiyelwe ye-NEMA 1.Kodwa-ke, isilinganiso se-NEMA 2 sinikeza ukuvikeleka okwengeziwe okuhlanganisa ukuvikeleka ekuconseni okukhanyayo noma ukuchaphazwa kwamanzi (ubufakazi bokuconsa).

I-NEMA 3R, 3RX:Izivalo ze-NEMA 3R kanye ne-3RX zidizayinelwe ukusetshenziswa ngaphakathi noma ngaphandle futhi zivikela emvuleni, likhithika, iqhwa, nokungcola, futhi zivimbela ukwakheka kweqhwa endaweni ebiyelwe kuyo.

I-NEMA 3, 3X:Izivalo ze-NEMA 3 kanye ne-3X azinamvula, azinethi, futhi azinalo uthuli futhi zenzelwe kokubili izinhlelo zokusebenza zasendlini nangaphandle.I-NEMA 3 kanye ne-3X ichaza ukuvikelwa okwengeziwe othulini ngale kwe-NEMA 3R noma 3RX ebiyelwe.

I-NEMA 3S, 3SX:Izivalo ze-NEMA 3S kanye ne-NEMA 3SX ziyazuza ekuvikelweni okufanayo njenge-NEMA 3, nokho, zinikeza ukuvikeleka lapho iqhwa libumba endaweni ebiyelwe futhi izohlala isebenza uma imbozwe yiqhwa.

I-NEMA 4, 4X:Izivalo ze-NEMA 4 kanye ne-NEMA 4X zenzelwe ukusetshenziswa ngaphakathi noma ngaphandle futhi zinikeza ukuvikela okufanayo njengendawo ebiyelwe ye-NEMA 3 enokuvikelwa okwengeziwe ekungeneni kwamanzi kanye/noma emanzini aqondiswe kwipayipi.Ngakho-ke, uma udinga ukuhlanza indawo ebiyelwe yakho ye-NEMA 4, akudingeki ukhathazeke ngamanzi alimaza izingxenye zakho zikagesi.

I-NEMA 6, 6P:Inikeza isivikelo esifanayo njengendawo ebiyelwe ye-NEMA 4, i-NEMA 6 inikeza isivikelo ekucwilisweni kwamanzi kwesikhashana noma eside (isilinganiso esingu-6P NEMA) kuze kufike ekujuleni okukhethiwe.

I-NEMA 7:Futhi yakhelwe izindawo eziyingozi, indawo ebiyelwe ye-NEMA 7 ayikwazi ukuqhuma futhi yenzelwe ukusetshenziswa endlini (eyakhelwe izindawo eziyingozi).

I-NEMA 8:Inikeza isivikelo esifanayo njengendawo ebiyelwe ye-NEMA 7, i-NEMA 8 ingasetshenziswa ngaphakathi nangaphandle (eyakhelwe izindawo eziyingozi).

I-NEMA 9:Izivalo ze-NEMA 9 azikwazi ukuvutha futhi zihloselwe ukusetshenziswa endlini ezindaweni eziyingozi.

I-NEMA 10:I-NEMA 10 evalekile ihlangabezana nezindinganiso ze-MSHA (Ukuphepha Kwezimayini Nokuphathwa Kwezempilo).

I-NEMA 12, 12K:Izivalo ze-NEMA 12 kanye ne-NEMA 12K zenzelwe ukusetshenziswa endlini ngenjongo evamile.Izivalo ze-NEMA 12 kanye ne-12K zivikela emanzini aconsayo namanzi, ziyamelana nokugqwala, futhi azibandakanyi ama-knockout (izimbobo ezishaywa kancane ezingasuswa ukuze kufakwe izintambo, izixhumi, kanye/noma amapayipi).

I-NEMA 13:Izivalo ze-NEMA 13 ezenjongo evamile, ukusetshenziswa kwasendlini.Zinikeza isivikelo esifanayo nezibiyelo ze-NEMA 12, kodwa ngesivikelo esengeziwe ekuconseni kanye/noma kumafutha afuthwe kanye nezinto zokupholisa.

*Qaphela: Indawo ebiyelwe ngo-“X” ikhombisa isilinganiso esimelana nokubola.
