NO.1 Chiyambi cha mita yamadzi
Mita yamadzi idayambira ku Europe. Mu 1825, Klaus waku Britain adapanga mita yamadzi yama tanki yokhala ndi zida zenizeni, kenako ndikubwezeretsanso mita imodzi yamadzi a piston, ma mita angapo amtundu wamajet vane ndi mita yamadzi yama helical.
Kugwiritsa ntchito ndikupanga mita yamadzi ku China kudayamba mochedwa. Mu 1879, chomera choyamba chamadzi ku China chidabadwira ku Lushunkou. Mu 1883, amalonda aku Britain adakhazikitsa chomera chachiwiri chamadzi ku Shanghai, ndipo ma mita amadzi adayambitsidwa ku China. M'zaka za m'ma 1990, chuma cha China chidapitilirabe kuthamanga kwambiri, msika wamagetsi wamadzi udayambiranso mwachangu, kuchuluka kwa mabizinesi ndi kuchuluka kwake kuwirikiza kawiri, nthawi yomweyo, mita zamadzi zingapo zanzeru, dongosolo lowerengera madzi mita ndi zinthu zina kuwuka.
NO.2 Mawotchi madzi mita ndi wanzeru mita madzi
Mawotchi amadzi mita
Mawotchi amadzi amagwiritsira ntchito poyesa mosalekeza, kuloweza ndikuwonetsa kuchuluka kwa madzi oyenda kudzera mu payipi yoyeserera momwe zinthu zilili. Kapangidwe kameneka kamapangidwa ndimete thupi, chophimba, kuyeza makina, kuwerengera makina, ndi zina zambiri.
Mawotchi amadzi mita, amatchedwanso miyambo mita madzi, ndi mtundu wa mita madzi amene chimagwiritsidwa ntchito ndi owerenga. Ndi ukadaulo wokhwima, mtengo wotsika komanso kuyeza kwakukulu, makina oyeseza madzi akadali ndi malo ofunikira kutchuka kwamamita anzeru masiku ano.
Wanzeru mita madzi
Mita yanzeru yamadzi ndi mtundu watsopano wamamita amadzi omwe amagwiritsa ntchito ukadaulo waukadaulo wamagetsi, ukadaulo wamakono waukadaulo ndi ukadaulo waluntha wamakadi a IC kuyesa kumwa madzi, kusamutsa data yamadzi ndi kukonza maakaunti. Poyerekeza ndi mita yamadzi yachikhalidwe, yomwe imangokhala ndi ntchito yosonkhanitsa komanso kuwonetsa cholozera cha madzi, ndikutukuka kwakukulu.
Mita yanzeru yamadzi imagwira ntchito mwamphamvu, monga kulipira pasadakhale, ma alamu osakwanira, osakhala ndi mita yowerengera. Kuphatikiza pa kujambula ndikuwonetsa kwamagetsi kagwiritsidwe ntchito ka madzi, itha kuyang'aniranso kagwiritsidwe ntchito ka madzi malinga ndi mgwirizano, ndikumaliza kuwerengetsera kuchuluka kwa madzi pamtengo wamadzi, ndipo imatha kusunga madzi nthawi yomweyo.
NO.3 Gulu la mita yamadzi
Amagawidwa ngati ntchito.
mita yamadzi yapachiweniweni ndi mita yamadzi yamafuta.
Kutentha
Amagawidwa mita yamadzi ozizira ndi mita yamadzi otentha.
Malinga ndi kutentha kwapakati, imatha kugawidwa m'madzi ozizira ndi mita yamadzi otentha
(1) Cold madzi mita: m'munsi malire kutentha sing'anga 0 ℃ ndi chapamwamba malire kutentha 30 ℃.
(2) Hot mita madzi: mita mita ndi sing'anga m'munsi malire kutentha 30 ℃ ndi malire chapamwamba 90 ℃ kapena 130 ℃ kapena 180 ℃.
Zofunikira m'maiko osiyanasiyana ndizosiyana pang'ono, mayiko ena amatha kufikira malire a 50 madigiri Celsius.
Mwa kukakamizidwa
Amagawidwa mita yamadzi wamba komanso mita yamagetsi.
Malinga ndi kupanikizika komwe kumagwiritsidwa ntchito, itha kugawidwa m'madzi wamba amadzi ndi kuthamanga kwa madzi mita. Ku China, kuthamanga kwama mita wamba madzi nthawi zambiri kumakhala 1MPa. Kuthamanga madzi mita ndi mtundu wa mita madzi ndi kuthamanga pazipita ntchito zoposa 1MPa. Amagwiritsidwa ntchito poyesa jakisoni wamadzi wapansi panthaka ndi madzi ena am'mafakitale akuyenda m'mapaipi.
Na. 4 Kuwerenga kwa mita yamadzi.
Kuyeza kwa kuchuluka kwa mita yamadzi ndi cubic mita (M3). Kuwerengera kwa mita kudzalembedwa mu cubic metres yonse, ndipo mantissa yochepera 1 cubic mita iphatikizidwa mgawo lotsatira.
Cholozera chikuwonetsedwa ndi mitundu yosiyanasiyana. Omwe amakhala ndi magawano okulirapo kuposa kapena ofanana ndi cubic mita imodzi ndi akuda ndipo amayenera kuwerengedwa. Ma mita osakwana 1 cubic onse ndi ofiira. Kuwerenga kumeneku sikofunikira.
NO.5 Kodi mita yamadzi ingakonzedwe ndi ife tokha?
Mita iliyonse yamadzi pakakhala zovuta zina, sizingasokonezedwe ndikukonzedwa popanda chilolezo, ogwiritsa ntchito amatha kudandaula kuofesi yamakampani a madzi, ndikutumiza ogwira ntchito kukakonza ndi kampani yamadzi.
