Chii chinonzi sando yemvura?
Nyundo yemvura iri mukukundikana kwesimba kamwe kamwe kana muvharuvhu yakavharwa nekukurumidza, nekuda kweiyo inertia yekumanikidzwa kwemvura kuyerera, iyo inoyerera inoputika wave inogadzirwa, senge nyundo, inodaidzwa kunzi nyundo yemvura.Simba rekumashure-uye-kumashure remvura inovhundutsa, dzimwe nguva yakakura, inogona kuputsa mavharuvhu nemapombi.
Kana vharuvhu yakazaruka yakavharwa kamwe kamwe, kuyerera kwemvura kunoita kumanikidza pavhavha uye pombi madziro.Nekuda kwemadziro akatsetseka epombi, iyo inotevera mvura inoyerera pasi pechiito che inertia inokurumidza kusvika pakakwirira uye inogadzira inoparadza mhedzisiro, iyo "mvura nyundo mhedzisiro" mumagetsi mechanics, ndiko kuti, yakanaka sando yemvura.Ichi chinhu chinofanira kutariswa pakuvaka mapaipi ekupa mvura.
Kusiyana neizvi, chivharo chakavharwa chinozarura kamwe kamwe chichabudisawo nyundo yemvura, inonzi nyundo yemvura yakaipa, iyo inewo simba rinoparadza, asi kwete sezvakaita yekare.Iyo yemagetsi pombi unit inokonzeresa kukanganisa kwekumanikidza uye nyundo yemvura mhedzisiro kana simba rakangoerekana ragurwa kana kutanga.Kuvhundutsa kwemafungu ekumanikidza kwakadaro kunopararira pedyo nepombi, izvo zvinotungamirira nyore nyore kukumanikidza kwepaipi kwepanzvimbo uye kukonzera kutsemuka kwepombi uye kukuvara kwemidziyo.Naizvozvo, kuchengetedzwa kwesando yemvura mhedzisiro inova imwe yehunyanzvi tekinoroji yeinjiniya yekupa mvura.
Mamiriro emvura sando:
1. Ivhavha inovhura kana kuvhara kamwe kamwe;
2. Chikwata chepombi chinomira kana chinotanga kamwe kamwe;
3. Single pombi kumvura yakakwirira (mvura kupa terrain kureba musiyano weanopfuura 20 metres);
4. Musoro wose wepombi (kana kushanda nesimba) yakakura;
5. Kumhanya kwemvura mupombi yemvura yakakurisa;
6. Pombi yemvura yakarebesa, uye nzvimbo inoshanduka zvikuru.
Kukuvadza kwesando yemvura effect:
Kuwedzera kwesimba kunokonzerwa nesando yemvura kunogona kusvika kakawanda kana kakapetwa kakapetwa kakapetwa kanokwana kushanda kwepombi. Kukuvadza kukuru kwekuchinja kukuru uku kwepombi ndiko:
1.Cause kudengenyeka kwakasimba kwepombi, pombi yejojo yakabviswa;
2. Kukuvadzwa kwevhavha, kudzvinyirira kwakakomba kwakanyanyisa kukonzera kuputika kwepombi, mvura inotakura network inoderedzwa;
3. Pane zvinopesana, kuderera kwakanyanya kunokonzera kuparara kwepombi, asiwo kukuvadza valve uye kugadzirisa;
4. Ikonzeresa kutendeuka kwepombi, kukuvadza midziyo yemukamuri yepombi kana mapaipi, zvinokonzeresa nzvimbo yepombi mafashama, zvichikonzera kukuvadzwa uye dzimwe njodzi huru, inokanganisa kugadzirwa uye hupenyu.
Matanho ekudzivirira ekubvisa kana kuderedza sando yemvura:
Kune matanho akawanda ekudzivirira panyundo yemvura, asi matanho akasiyana anofanira kutorwa maererano nezvikonzero zvinogona kukonzera nyundo yemvura.
1. Kuderedza kuyerera kwepombi yekufambisa mvura kunogona kuderedza nyundo yemvura kune imwe nhanho, asi ichawedzera dhayamita yepombi yekufambisa mvura uye kuwedzera mari yeprojekti.Kugoverwa kwemitsara yekufambisa mvura kunofanirwa kutariswa kudzivirira kuitika kwehumps kana kungoerekana kushanduka kwemateru.Ukuru hwenyundo yemvura inonyanya kuenderana nemusoro wejometri wekamuri yepombi.Iyo yakakwirira musoro wejometri ndeye, iyo yakakura kukosha kwenyundo yemvura ndeye.Nokudaro, musoro wepombi unonzwisisika unofanirwa kusarudzwa maererano nemamiriro ezvinhu chaiwo.Mushure mekunge pombi yamira mutsaona, pombi inofanira kutangwa apo pombi kuseri kwevhavhavha yecheki yakazadzwa nemvura.Usavhura zvakakwana pombi yekubuda kwevhavha paunotanga pombi, kana zvisina kudaro inoburitsa simba guru remvura.Tsaona zhinji dzesando dzemvura mumapombi emvura dzinoitika pasi pechiitiko ichi.
2. Seta mudziyo wekubvisa sando yemvura:
(1) Constant pressure control tekinoroji:
Sezvo kudzvinyirirwa kwemvura inoyerera inogara ichichinja nekuchinja kwemamiriro ekushanda, chiitiko chekushomeka kwepasi kana kuwandisa kunowanzoitika muhurongwa hwekushanda kwehurongwa, huri nyore kugadzira nyundo yemvura, zvichikonzera kuparadzwa kwepombi nemidziyo. .Iyo otomatiki yekudzora sisitimu inogamuchirwa, kuburikidza nekuonekwa kwepombi network pressure, mhinduro yekudzora pombi kutanga, kumira uye kukurumidza kudzora, kutonga kuyerera, uyezve kuita kuti kumanikidzwa kuchengetedze imwe nhanho.Kupa mvura kwepombi kunogona kuiswa ne kudzora iyo microcomputer kuchengetedza inogara ichimanikidza mvura, kudzivirira yakawandisa kudzvanya kushanduka, uye kuderedza mukana wesando yemvura.
(2) Isa nyundo yemvura inobvisa
Midziyo iyi inonyanya kudzivirira sando yemvura kumisa pombi, iyo inowanzoiswa pedyo nepombi inobuditsa pombi.Iyo inoshandisa kudzvanywa kwepombi pachayo sesimba rekuona iyo yakaderera kumanikidza otomatiki chiito, ndiko kuti, kana kudzvanywa kwepombi kwakadzikira pane yakatarwa yekudzivirira kukosha, chiteshi chemvura chinongovhura kuburitswa kwemvura uye kudzoreredzwa, saka sekuenzanisa kudzvanywa kwepombi yenzvimbo uye kudzivirira kukanganisa kwesando yemvura pamidziyo uye pombi.Eliminator inogona kazhinji kukamurwa kuita michina uye hydraulic marudzi maviri, mechanical eliminator chiito nekudzoreredza kwemanyore, hydraulic eliminator inogona kugadzirisa otomatiki.
(3)Isa inononoka-yekuvhara cheki vharafu pane yakakura dhayamita yemvura pombi yekubuda pombi.
Inogona kunyatsobvisa nyundo yemvura inomisa pombi, asi nekuda kwekuti pane imwe huwandu hwemvura inodzokera shure panguva yekushanda kwevharuvhu, tsime rekusveta rinofanira kunge rine pombi inoputika.Kune marudzi maviri eanononoka kuvhara cheki mavharuvhu: inorema sando mhando uye simba rekuchengetedza mhando.Iyi valve inogona kugadzirisa nguva yekuvhara yevhavha mukati meimwe mutsara sezvinodiwa.Kazhinji, vharuvhu inovharwa ne70% ~ 80% mukati me3 ~ 7 s mushure mekudzima, uye yasara 20% ~ 30% yenguva yekuvhara inogadziriswa zvinoenderana nemamiriro epombi uye pombi, kazhinji muhuwandu hwe. 10 ~ 30 s.Zvakakosha kucherechedza kuti kana paine hump mupombi uye sando yemvura yebhiriji inoitika, basa revhavha yekuvhara inononoka inoshanda zvakanyanya.
(4) Isa Iyo One-Way Pressure Regulating Shongwe
Yakavakwa pedyo nechiteshi chekupomba kana panzvimbo yakakodzera yepombi, kureba kwenzira imwe chete yekusurge tower kwakadzikira pane kudzvanywa kwepombi ipapo.Kana kudzvanywa kwepombi kwakadzikira pane mwero wemvura mushongwe, shongwe inokwirisa inodzoreredza mvura kune pombi kudzivirira mbiru yemvura kubvaruka uye kudzivirira kuvhara sando yemvura.Zvisinei, simba rayo-kuderedza simba panyundo dzemvura kunze kwepombi-inomisa sando dzemvura dzakadai sevhavha-inovhara mvura yemvura inogumira.Mukuwedzera, kushanda kwevhavhavha yekuongorora inoshandiswa mune imwe-nzira yekumanikidzika inodzora shongwe inovimbika zvachose.Kana iyo valve yakundikana, inogona kutungamirira kune chiitiko chikuru.
(5) Seta pombi yekupfuura (vharuvhu) muchiteshi chepombi.
Munguva yekushanda kwemaitiro epombi, cheki chevhavha yakavharwa nokuti mvura inomanikidza padivi remvura yepombi yakakwirira kudarika mvura yemvura padivi rekusveta.Apo pombi inomira kamwe-kamwe mushure menjodzi, kumanikidzwa kwepombi yepombi kunoderera zvakanyanya, nepo kumanikidzika padivi rekusveta kunokwira zvakanyanya.Pasi pekumanikidzwa uku kwakasiyana, iyo inopfupika yakakwira-kudzvanywa kwemvura mupombi huru yekunyura ndiyo inopfupikisa yakaderera-kudzvanywa mvura inosundira cheki yevharuvhu ndiro kune yekumanikidza mvura pombi hombe, uye inowedzera kuderera kwemvura ipapo.Kune rumwe rutivi, kudzvinyirirwa kwesando yemvura padivi rekusveta pombi kunoderedzwawo.Nenzira iyi, nyundo yemvura inosimuka uye inowira kumativi ose epombi yepombi inodzorwa, nokudaro zvinobudirira kuderedza nekudzivirira kukuvadza kwenyundo yemvura.
(6) Isai ma-multi-stage check valve
Mune pombi refu yemvura, imwe kana kupfuura mavharuvhu ekutarisa anowedzerwa kuti aparadzanise pombi yemvura muzvikamu zvakawanda, uye mavharuvhu ekutarisa anoiswa pachikamu chimwe nechimwe.Kana mvura iri mupombi yekufambisa mvura ichiyerera ichidzokera kumashure panguva yesando yemvura, vharafu yega yega inovharwa imwe neimwe kugovera kuyerera kwemvura yekumashure muzvikamu zvakawanda.Nekuti iyo hydrostatic musoro mupombi yega yega yekufambisa mvura (kana kuti backwash mvura inoyerera chikamu) idiki, sando yemvura inokwira inoderera.Iyi chiyero chekudzivirira inogona kushandiswa zvinobudirira mune yakakura kukwirira musiyano weiyo geometric mvura yekupa.Asi mukana wekuparadzaniswa kwembiru yemvura haugone kubviswa.Kukanganisa kwayo kukuru ndeyekuti simba rekushandisa pombi rinowedzera uye mutengo wemvura unowedzera panguva yekushanda.
(7) Iyo otomatiki yekuburitsa uye mudziyo wekupa mhepo inoiswa panzvimbo yakakwirira yepombi kuderedza kukanganiswa kwesando yemvura papombi.
