NO.1 Kwakatangira mita yemvura
Mita yemvura yakatanga muEurope. Muna 1825, Klaus weBritain akagadzira mita yematangi emvura ine huremu ine hunhu chaihwo, ichiteverwa nekudzosera mita imwechete yemvura yepiston, jet vane mhando yemamita emvura uye helical vane mhando yemamita emvura.
Iko kushandiswa uye kugadzirwa kwemamita emvura muChina kwakatanga kunonoka. Muna 1879, chirimwa chekutanga chemvura cheChina chakazvarwa muLushunkou. Muna 1883, vezvemabhizimusi veBritain vakagadza wechipiri chirimwa chemvura muShanghai, uye mamita emvura akatanga kuunzwa kuChina. Mumakore ekuma1990, hupfumi hweChina hwakaramba huchikurumidza kumhanya, iyo indasitiri yemamita emvura yakawedzerawo nekukurumidza, huwandu hwemabhizimusi uye huwandu hwezvakabuda zvakapetwa kaviri, panguva imwechete, akasiyana metres emvura, mita yemvura yekuverenga uye zvimwe zvigadzirwa zvakatanga. kusimuka.
NO.2 Mechanical mvura mita uye akangwara mvura mita
Mechanical mvura mita
Mechaniki yemvura mita inoshandiswa kuenderera mberi kuyera, kubata nemusoro uye kuratidza huwandu hwemvura inoyerera kuburikidza nepombi yekuyera pasi pemamiriro ekuyerwa ekushanda. Chimiro chakakosha chinonyanya kuverengerwa nemete muviri, chifukidzo, kuyera mashandiro, kuverenga mashandiro, nezvimwe.
Mechanical mvura mita, inozivikanwawo seyakajairwa mita yemvura, imhando yemamita emvura ayo anoshandiswa zvakanyanya nevashandisi. Neruzivo rwekukura, mutengo wakaderera uye kuyerwa kwepamusoro kwakaringana, metre yemvura inoramba iine chinzvimbo chakakosha mukuzivikanwa kwanhasi kwemamita emvura akangwara.
Akangwara mita yemvura
Akangwara mita yemvura imhando nyowani yemamita emvura ayo anoshandisa echizvino microelectronics tekinoroji, yazvino sensor tekinoroji uye akangwara IC kadhi tekinoroji kuyera kushandiswa kwemvura, kuendesa data remvura uye kugadzirisa maakaundi. Inofananidzwa neyemita yemvura mita, iyo chete ine basa rekuyerera kuunganidzwa uye mechiratidzo pointer kuratidza yekushandisa mvura, iko kufambira mberi kukuru.
Akangwara mita yemvura ine mabasa ane simba, akadai sekubhadharisa mari, isina kukwana bharamu, hapana kuverenga mita yemanyorero. Kunze kwekurekodha uye kuratidza kwemagetsi kwekushandisa kwemvura, inogona zvakare kudzora kushandiswa kwemvura zvinoenderana nechibvumirano, uye nekupedzisa kuverenga kwechaji yemvura yematanho emvura mutengo, uye inogona kuchengeta data remvura panguva imwe chete.
NO.3 Kupatsanura kwemamita emvura zvivakwa
Yakarongerwa semabasa.
mita yemvura yemunharaunda uye mita yemvura maindasitiri.
Nekupisa
Yakakamurwa kuita mita yemvura inotonhora uye mita yemvura inopisa.
Zvinoenderana netembiricha yepakati, inogona kuganhurwa kuita mita yemvura inotonhora uye mita yemvura inopisa
(1) Mvura inotonhorera yemvura: iyo yepasi muganho tembiricha yepakati iri 0 ℃ uye yepamusoro muganho tembiricha iri 30 ℃.
(2) Hot mita yemvura: mita yemvura ine yepakati yakadzika muganho tembiricha ye30 ℃ uye yepamusoro muganho we90 ℃ kana 130 ℃ kana 180 ℃.
Zvinodiwa nenyika dzakasiyana zvakasiyana zvishoma, dzimwe nyika dzinogona kusvika pamuganhu wepamusoro we50 degrees Celsius.
Nekumanikidza
Iyo yakakamurwa kuita yakajairika mita yemvura uye yakanyanya kumanikidza mita yemvura.
Zvinoenderana nekumanikidza kunoshandiswa, inogona kuganhurwa kuita mita yemvura uye yakanyanya kumanikidza mita yemvura. MuChina, iko kumanikidzwa kwemamita emvura akajairika kazhinji 1MPa. Yakakwira kumanikidza mvura mita ndeye mhando yemamita emvura ine yakanyanya kushanda kumanikidza anodarika 1MPa. Inonyanya kushandiswa kuyera pasi pevhu jekiseni remvura uye mamwe maindasitiri mvura inoyerera nepombi.
Kwete. 4 mita yemvura kuverenga.
Chidimbu chekuyera kwemamita emvura huwandu hwamamirimita (M3). Iyo kuverenga kwemamita kuverenga kunonyorwa muhuwandu hwakazara hwemamirimita, uye mantissa isingasviki 1 cubic mita ichasanganisirwa munharaunda inotevera.
Iyo pointer inoratidzwa nemavara akasiyana. Avo vane kupatsanura kukosha kwakakura kupfuura kana kuenzana ne 1 cubic mita vatema uye vanofanirwa kuverengwa. Iwo asingasviki 1 cubic mita ese akatsvuka. Kuverenga uku hakudiwe.
NO.5 Ko mita yemvura ingagadziriswe pachedu here?
Chero mita yemvura muhupo hwezvinetso zvisina kujairika, haigone kubviswa nekugadziriswa pasina mvumo, vashandisi vanogona kunyunyuta zvakananga kuhofisi yebhizinesi yekambani yemvura, uye kutumira vashandi kunogadzirisa nekambani yemvura.
