Kune akawanda matanho ekudzivirira nyundo yemvura, asi matanho akasiyana anofanira kutorwa zvichienderana nezvinokonzeresa nyundo yemvura.

1.Kuderedza kuyerera kwepombi yemvura kunogona kuderedza nyundo yemvura kune imwe nhanho, asi inowedzera dhayamita yepombi yemvura uye kuwedzera purojekiti yekutsvaga. Pakuisa mapaipi emvura, kufunga kunofanirwa kucherechedzwa kudzivirira humps kana shanduko huru pamateru.

Deredza urefu hwepombi yemvura. Iyo yakareba iyo pombi, inowedzera kukosha kwesando yemvura kana iyo split case pombi yemvura inomiswa. Kubva pane imwe nzvimbo yekupomba kusvika kune mbiri dzekupomba, tsime rekusveta mvura rinoshandiswa kubatanidza mapombi maviri.

Kukura kwesando yemvura kana pombi yamira kunonyanya kuenderana nemusoro wejometri wekamuri yepombi. Iyo yakakwirira yemusoro wejometri, iyo yakakura kukosha kwesando yemvura kana pombi yamiswa. Nokudaro, musoro wepombi unonzwisisika unofanirwa kusarudzwa zvichienderana nemamiriro chaiwo emunharaunda.

Mushure mokumisa pombi nekuda kwenjodzi, pombi kuseri kwevhavha yekuongorora inofanira kuzadzwa nemvura isati yatanga pombi.

Paunenge uchitanga pombi, usanyatso kuvhura iyo yakakamurwa kese yemvura pombi yekubuda vharafu, zvikasadaro kukanganiswa kwemvura kukuru kuchaitika. Tsaona huru dzesando dzemvura mumapombi akawanda dzinowanzoitika mumamiriro ezvinhu akadaro.

2. Gadzira mudziyo wekubvisa sando yemvura

(1) Kushandisa inogara voltage control tekinoroji

Iyo PLC otomatiki yekudzora sisitimu inogamuchirwa kuita frequency kushandura kumhanya kudzora papombi, uye kuita otomatiki kudzora pakushanda kweiyo yese mvura yekupa pombi yekamuri system. Sezvo kudzvinyirirwa kwepombi yemvura yepombi network inoramba ichichinja nekuchinja kwemamiriro ekushanda, kuderera kuderera kana kuwandisa kunowanzoitika panguva yekushanda kwehurongwa, izvo zvinogona kukonzera nyore nyundo yemvura, zvichiita kuti kukuvara kwepombi nemichina. A PLC otomatiki control system inoshandiswa kudzora pombi network. Kuonekwa kwekumanikidza, kutonga kwemhinduro yekutanga uye kumira kwepombi yemvura uye kukurumidza kugadzirisa, kutonga kwekuyerera, uye nokudaro kuchengetedza kudzvinyirira pane imwe nhanho. Iyo yemvura yekumanikidza yepombi inogona kusetwa nekudzora iyo microcomputer kuchengetedza inogara ichimanikidza mvura yekupa uye kudzivirira yakawandisa kudzvanya kushanduka. Mukana wesando yemvura wakaderedzwa.

(2) Isa mvura yekubvisa sando

Ichi chishandiso chinonyanya kudzivirira sando yemvura kana pombi yamiswa. Iyo inowanzoiswa padhuze nepombi yekubuda yepombi yemvura yekuparadzanisa. Iyo inoshandisa kudzvanywa kwepombi pachayo sesimba rekuona yakaderera-kumanikidza otomatiki chiito. Ndiko kuti, kana kudzvinyirirwa mupombi kwakadzikira pane yakatarwa yekudzivirira kukosha, chiteshi chemvura chinozovhurika otomatiki kubvisa mvura. Kubvisa kudzvanyirira kunoshandiswa kuenzanisa kudzvanywa kwepombi dzenzvimbo uye kudzivirira kukanganisa kwesando yemvura pamidziyo nemapaipi. Eliminators anogona kazhinji kukamurwa kuva mhando mbiri: mechanical uye hydraulic. Mechanical eliminators anodzoserwa nemaoko mushure mekuita, nepo hydraulic eliminators inogona kugadzikwa patsva.

(3) Isa inononoka-yekuvhara cheki valve pane yakakura-diameter pombi yemvura yakatsemuka ppombi yekuburitsa

Inogona kunyatsobvisa nyundo yemvura kana pombi yamira, asi nekuda kwekuti imwe huwandu hwemvura huchayerera shure kana vharuvhu yaitwa, mvura yekusveta tsime inofanira kunge iine pombi inoputika. Kune marudzi maviri ekunonoka-kuvhara cheki mavharuvhu: sando mhando uye simba rekuchengetedza mhando. Rudzi urwu rwevharuvhu runogona kugadzirisa nguva yevhavha yekuvhara mukati meimwe siyana sezvinodiwa. Kazhinji, vharuvhu inovhara 70% kusvika 80% mukati me3 kusvika 7 seconds mushure mekupera kwemagetsi. Iyo yasara 20% kusvika 30% nguva yekuvhara inogadziriswa zvinoenderana nemamiriro epombi yemvura uye pombi, kazhinji muchikamu chegumi kusvika makumi matatu masekonzi. Zvakakosha kuziva kuti kana pane hump mupombi uye nyundo yemvura inoitika, basa revhavha yekuvhara zvishoma nezvishoma ishoma.

(4) Gadzira shongwe yenzira imwe chete yekumanikidza

Inovakwa padyo nechiteshi chekupomba kana panzvimbo yakakodzera mupombi, uye kureba kwenzira imwe chete yekumanikidza inodzora shongwe yakaderera pane yekumanikidza kwepombi ipapo. Kana dzvinyiriro iri mupombi yakadzikira pane mwero wemvura mushongwe, nhanho inodzora mvura inodzoreredza mvura kune pombi kudzivirira mbiru yemvura kubvaruka uye kubhuroka sando yemvura. Zvisinei, simba rayo-kuderedza simba panyundo yemvura kunze kwepombi-kumisa nyundo yemvura, yakadai sevhavha-inovhara mvura nyundo, inogumira. Mukuwedzera, kushanda kwevhavha yenzira imwe inoshandiswa mune imwe-nzira yekumanikidza inodzora shongwe inofanira kuva yakavimbika zvachose. Kana vharuvhu yakundikana, inogona kukonzera nyundo huru yemvura.

(5) Misa pombi yokunzvenga (vharufu) muchiteshi chepombi

Apo pombi yepombi iri kushanda zvakajairika, cheki chevhavha yakavharwa nokuti mvura inodzvinyirira padivi repombi yakakwirira kudarika mvura yemvura padivi rekusveta. Kana simba retsaona richidzima kamwe kamwe rinomisa pombi yemvura inopatsanurwa, kudzvanywa kwepombi yepombi yemvura kunodonha zvakanyanya, ukuwo kudzvanywa kuri padivi rekusveta kuchikwira zvakanyanya. Pasi pekumanikidzwa uku kwakasiyana, iyo inopfupika yakakwira-kudzvanywa kwemvura mumvura yekusveta pombi hombe inosunda kuvhura cheki yevharuvhu ndiro uye inoyerera ichienda kune inopfupika yakaderera-inodzvinyirira mvura mumhepo yekumanikidza mvura pombi huru, zvichiita kuti kuderera kwemvura uko kuwedzere; kune rumwe rutivi, pombi yemvura Mvura yenyundo yemvura inokwira padivi rekusveta inoderedzwawo. Nenzira iyi, nyundo yemvura inosimuka uye kudonha kwemhepo kumativi ose epombi yemvura inodzorwa, nokudaro kuderedza nekudzivirira njodzi dzesando dzemvura.

(6) Gadzira ma-multi-stage check valve

Mune pombi refu yemvura, wedzera imwe kana mamwe mavharuvhu ekutarisa, patsanura pombi yemvura muzvikamu zvakawanda, uye isa cheki cheki pachikamu chimwe nechimwe. Apo mvura iri mupombi yemvura inoyerera ichidzoka munguva yesando yemvura, vharafu yega yega yecheki inovharwa imwe pashure peimwe kuti iparadzanise kuyerera kwemashure muzvikamu zvakawanda. Sezvo musoro wehydrostatic muchikamu chimwe nechimwe chepombi yemvura (kana kuti backflush flow section) iri diki, mwero wekuyerera kwemvura unodzikira. Hammer inosimudzira. Ichi chiyero chekudzivirira chinogona kushandiswa zvinobudirira mumamiriro ezvinhu apo iyo geometric mvura inopa kureba musiyano yakakura; asi haigone kubvisa mukana wekuparadzaniswa kwembiru yemvura. Kukanganisa kwayo kukuru ndekwe: kuwedzera simba rekushandisa pombi yemvura panguva yekushanda kwakajairika uye kuwedzera mari yekupa mvura.
