Sando yemvura inonzi nyundo yemvura nekuda kwe inertia yekumanikidzwa kwemvura kuyerera apo simba rinobva ragurwa kamwe kamwe kana vharafu yakavharwa nekukurumidza, iyo inoburitsa mvura inoyerera kuvhunduka wave, kungofanana nesando inorova. Iyo yekumashure uye yekumberi simba remvura shock wave dzimwe nguva inogona kuve yakakura kwazvo, nekudaro ichikuvadza valve uye pombi yemvura.
Kana vharuvhu yakazaruka yakavharwa kamwe kamwe, kuyerera kwemvura kunoburitsa kumanikidza pavhavha uye pombi madziro. Pamusana pemadziro epombi yakatsetseka, mvura inotevera inoyerera inokurumidza kusvika pakakwirira pasi pechiito che inertia uye inogadzira mhedzisiro inoparadza, iyo "mvura nyundo mhedzisiro" mu hydrodynamics, ndiko kuti, yakanaka nyundo yemvura. Ichi chinhu chinofanira kutariswa pakuvaka pombi yekupa mvura.
Pane zvinopesana, mushure mokunge vheji yakavharwa yakavhurwa kamwe kamwe, ichaitawo nyundo yemvura, inonzi nyundo yemvura yakaipa, iyo inewo imwe simba rinoparadza, asi haisi yakakura seyokutanga. Kana iyo yemagetsi yepombi yemvura inongoerekana yadzimwa kana kutangwa, inokonzeresa kudzvanywa uye kuita sando yemvura. Iyi dzvinyiriro yekuvhundutsa wave inopararira papombi, izvo zvinogona kutungamira nyore kudzvinyirira kwepanzvimbo kwepombi, zvichikonzera kuputika kwepombi uye kukuvara kwemidziyo. Naizvozvo, kudzivirira nyundo yemvura yave imwe yeakakosha matekinoroji einjiniya yekupa mvura.
Mamiriro emvura sando
1. Kamwe kamwe kuvhura kana kuvhara kwevhavha;
2. Kamwe kamwe kumira kana kutanga kwepombi yemvura unit;
3. Kuendesa mvura kubva papombi imwe kuenda kunzvimbo yakakwirira (iyo topographic elevation musiyano wemvura inodarika 20m);
4. Musoro wose (kana kushanda nesimba) wepombi yemvura yakakura;
5. Kuwedzera kuyerera kwepaipi mupombi yekufambisa mvura;
6. Pombi yemvura yakarebesa uye nzvimbo inoshanduka zvikuru.
Kukuvadza kwemvura sando effect
Kukwira kwesimba kunokonzerwa nesando yemvura kunogona kusvika kakawanda kana kunyange makumi enguva dzenguva dzose dzekushanda kwepombi. Njodzi dzeiyi dzvinyiriro huru yekuchinja kune pombi system inonyanya kusanganisira:
1. Ikonzeresa kuzunguzika kwakasimba kwepombi uye bvisa kubatana kwepombi;
2. Ivhavha yakakuvadzwa, uye kudzvinyirira kwakakomba kwakanyanyisa, zvichiita kuti pombi inoputika uye kuderedza kuderedzwa kwemvura yemvura;
3. Pane zvinopesana, kuderera kwakanyanya kunokonzera kuparara kwepombi uye kukuvadza valve uye kugadzirisa zvikamu;
4. Ita kuti pombi idzokere kumashure, kukuvadza midziyo kana pombi mukamuri yepombi, kunyudza zvakanyanya mukamuri yepombi, kukonzeresa kukuvadzwa uye dzimwe njodzi huru, uye kukanganisa kugadzirwa uye hupenyu.
Matanho ekudzivirira ekubvisa kana kuderedza sando yemvura
Kune akawanda matanho ekudzivirira nyundo yemvura, asi matanho akasiyana anofanira kutorwa maererano nezvinokonzeresa nyundo yemvura.
1. Kuderedza kuyerera kwepombi yekufambisa mvura kunogona kuderedza dzvinyiriro yesando yemvura kusvika kumwero wakati, asi zvinozowedzera dhayamita yepombi yekufambisa mvura uye kuwedzera mari yepurojekiti. Panguva yekurongeka kwepombi yekufambisa mvura, hump kana kuchinjika kwakapinza kwemateru kunodziviswa sezvinobvira. Saizi yepombi inomisa sando yemvura inonyanyoenderana nemusoro wegeometric wepombi imba. Iyo yakakwirira iyo geometric musoro ndeye, iyo yakakura kukosha kwepombi yekumisa mvura sando. Nokudaro, musoro wepombi unonzwisisika uchasarudzwa maererano nemamiriro ezvinhu chaiwo. Mushure mekuvhara kwepombi yechimbichimbi, pombi ichatangwa mushure mekunge pombi kuseri kwevharuvhu yecheki yazadzwa nemvura. Paunenge uchitanga pombi, usanyatsovhura vharuvhu yekubuda yepombi, zvikasadaro inoburitsa simba rakakura remvura. Tsaona huru dzesando dzemvura dzepombi dzepombi dzinonyanya kukonzerwa munyaya iyi.
2. Seta mvura sando yekubvisa mudziyo
(1) Constant pressure control tekinoroji inogamuchirwa:
Sezvo kudzvinyirirwa kwepombi yemvura yepombi network ichichinja nguva dzose nekuchinja kwemamiriro ekushanda, kuderera kwepasi kana kuwandisa kunowanzoitika panguva yekushanda kwegadziriro, iyo iri nyore kugadzira nyundo yemvura, zvichiita kuti kukuvadzwa kwepombi nemidziyo, iyo otomatiki kudzora. sisitimu inogamuchirwa kudyisa kutanga, kumira uye kukurumidza kudzora pombi yemvura kuburikidza nekuonekwa kwepombi network kudzvanywa, kudzora kuyerera, uyezve kuchengetedza imwe nhanho yekumanikidza, Iyo pombi yekupa mvura yekumanikidza inogona kusetwa nekudzora microcomputer kuchengetedza inogara ichimanikidza mvura, dzivirira yakawandisa kudzvanya kushanduka uye kuderedza mukana wesando yemvura.
(2) Isai chinobvisa sando yemvura
Midziyo yacho inonyanya kushandiswa kudzivirira sando yemvura kubva pakumisa pombi. Inowanzoiswa pedyo nepombi yekubuda nayo yepombi yemvura. Kudzvanywa kwepombi pachayo kunoshandiswa sesimba rekuona yakaderera-kudzvanya otomatiki chiito, ndiko kuti, kana kudzvanywa kwepombi kwakadzikira pane yakatarwa yekudzivirira kukosha, iyo yekubuda kwemvura inovhurika otomatiki kuburitsa mvura nekumanikidza, kuti kuenzanisa kudzvanywa kwepombi yenzvimbo uye kudzivirira kukanganisa kwesando yemvura pamidziyo uye pombi, Kazhinji, chinobvisa chinogona kukamurwa kuita mechanical mhando uye hydraulic type. Mushure meiyo mechanic eliminator ichiita, inogona kudzoreredzwa nemaoko, uye iyo hydraulic eliminator inogona kumisikidzwa otomatiki.
(3) Isa inononoka yekuvhara cheki vharafu papombi yekubuda yepombi yemvura yakakura dhayamita
Inogona kunyatso kubvisa nyundo yemvura yekuvharwa kwepombi, asi nekuda kwekuti kune imwe huwandu hwemvura yekudzokera shure kana vharuvhu ichiita, tsime rekusveta rinofanira kunge riine pombi inofashukira. Kunonoka kuvhara cheki vharafu ine marudzi maviri: inorema sando mhando uye simba rekuchengetedza mhando. Nguva yekuvhara yevhavha inogona kugadziriswa mukati mehumwe huwandu sezvinodiwa. Kazhinji, vharuvhu inovharwa 70% ~ 80% mukati me3 ~ 7 s mushure mekupera simba, uye yasara 20% ~ 30% nguva yekuvhara inogadziriswa maererano nemamiriro epombi yemvura uye pombi, kazhinji muhuwandu hwe10 ~ 30 s. Zvakakosha kucherechedza kuti kana paine hump mupombi yekuvharisa sando yemvura, inononoka kuvhara yekuvhara valve inoshanda zvakanyanya.
(4) Imwe nzira Surge Tower
Ichavakwa padyo nechiteshi chepombi kana panzvimbo yakakodzera yepombi, uye kureba kwenzira imwe chete yekusevha tank kunenge kwakadzikira pane kudzvanywa kwepombi ipapo. Kana kudzvanywa kwepombi kwakadzikira pane mwero wemvura mushongwe, tangi rekugezera rinogadzira mvura kuenda papombi kudzivirira mbiru yemvura kubvaruka uye kudzivirira bhiriji nyundo yemvura. Nekudaro, iyo depressurization maitiro pasando yemvura kunze kwepombi yekumisa sando yemvura, senge vharafu inovhara mvura sando, inogumira. Mukuwedzera, kushanda kwevhavha yenzira imwe chete inoshandiswa mune imwe-nzira yekumanikidza inodzora shongwe ichave yakavimbika zvachose. Kana vharuvhu yakundikana, inogona kutungamirira kunjodzi huru
(5) Pombi yebypass (vharuvhu) yakaiswa muchiteshi chepombi
Panguva yekushanda kwepombi yepombi, cheki chevhavha yakavharwa nokuti mvura inopisa padivi remvura yepombi yakakwirira kudarika iyo padivi rekusveta mvura. Apo pombi inomira kamwe-kamwe nekuda kwekukundikana kwesimba, kudzvanywa kwepakubuda kwepombi yemvura kunoderera zvakanyanya, nepo kumanikidza kudivi rekusveta kunokwira zvakanyanya. Pasi pekumanikidzwa uku kwakasiyana-siyana, mvura inofamba yakawanda mupombi huru yekusveta ndiyo inofamba yakaderera-inodzvinyirira mvura inosundira cheki chevhavha ndiro kuti iende kune yakamanikidzwa yemvura pombi huru, uye inowedzera mvura shoma shoma ipapo; Kune rumwe rutivi, kukwira kwesimba renyundo yemvura padivi rekusveta pombi yemvura kunoderedzwawo. Nenzira iyi, nyundo yemvura inosimuka uye kudonha kwekumanikidza pamativi ese epombi yemvura inodzorwa, kuitira kuti inyatso kudzikisa uye kudzivirira kukuvadza kwesando yemvura.
(6) Isai ma-multi-stage check valve
Mupombi yakareba yekufambisa mvura, imwe kana kupfuura mavharuvhu ekutarisa anowedzerwa kuti aparadzanise pombi yekufambisa mvura muzvikamu zvakawanda, uye mavharuvhu ekutarisa anoiswa pachikamu chimwe nechimwe. Kana mvura iri mupombi yekuendesa mvura ichiyerera ichidzoka mugadziriro yesando yemvura, vharafu yega yega yecheki inovharwa zvakatevedzana kuti igovane kuyerera kwe backwash muzvikamu zvakawanda. Nekuti iyo hydrostatic musoro muchikamu chega chega chepombi yekuunza mvura (kana backwash kuyerera chikamu) idiki, iyo sando yemvura inokwira inodzikira. Ichi chiyero chekudzivirira chinogona kushandiswa zvinobudirira mune yakakura geometric mvura inopa kureba musiyano; Nekudaro, mukana wekuparadzaniswa kwembiru yemvura haugone kubviswa. Kukanganisa kwayo kukuru ndeyekuti simba rekushandisa pombi yemvura rinowedzera uye mutengo wekupa mvura unowedzera panguva yekushanda kwakajairika.
(7) Otomatiki echaust uye mhepo yekuzadzazve midziyo yakaiswa panzvimbo dzakakwirira dzepombi kuderedza kukanganiswa kwesando yemvura papombi.
