Chii chinonzi Water Hammer?
Nyundo yemvura ndeye apo pane kamwe-kamwe simba kupera kana kana vharafu yakavharwa nekukurumidza, nekuda kwe inertia yekumanikidzwa kwemvura kuyerera, kuvhunduka kwemvura kuyerera kunogadzirwa, senge sando inorova, saka inonzi nyundo yemvura. .Simba rinogadzirwa nekumashure nekumashure masaisai emvura inoyerera, dzimwe nguva yakakura kwazvo, inogona kukanganisa mavharuvhu nemapombi.
Kana vheji yakazaruka yakavharwa kamwe kamwe, mvura inoyerera ichipikisana nevhavha uye pombi rusvingo, ichigadzira kumanikidza.Pamusana pemadziro akatsetseka epombi, mvura inotevera inoyerera inokurumidza kusvika pakakwirira pasi pechiito che inertia uye inogadzira kukanganisa.Iyi ndiyo "sando yemvura" mumagetsi mechanics, kureva, sando yemvura yakanaka.Ichi chinhu chinofanira kutariswa pakuvaka mapaipi ekupa mvura.
Pane zvinopesana, mushure mokunge vheji yakavharwa yakavhurwa kamwe kamwe, ichaitawo nyundo yemvura, iyo inonzi nyundo yemvura yakaipa.Rinewo rimwe simba rokuparadza, asi harina kukura sepakutanga.Kana iyo yemagetsi yepombi yemvura yemagetsi ikaerekana yapera simba kana kutanga kumusoro, zvinokonzeresa kuvhunduka uye nyundo yemvura.Kuvhundutsa kwepaipi iyi kunopararira pedyo nepombi, izvo zvinogona kutungamirira nyore nyore kukumanikidza kwepaipi kwepanzvimbo, zvichikonzera kuputika kwepombi uye kukuvara kwemidziyo.Naizvozvo, kudzivirira nyundo yemvura yave imwe yeakakosha matekinoroji muinjiniya yekupa mvura.
Mamiriro emvura sando
1. Ivhavha inovhurika kamwe kamwe kana kuvhara;
2. Chikwata chepombi yemvura chinongoerekana chamira kana kutanga;
3. Single-pombi kuendeswa kwemvura kunzvimbo dzakakwirira (mvura inogovera terrain kureba musiyano inodarika 20 metres);
4. Musoro wose (kana kushanda nesimba) wepombi yakakura;
5. Velocity yemvura mupombi yemvura yakakurisa;
6. Pombi yemvura yakarebesa uye nzvimbo inoshanduka zvikuru.
Ngozi dzesando yemvura
Kuwedzera kwesimba kunokonzerwa nesando yemvura kunogona kusvika kakawanda kana kunyange kakapetwa kakapetwa kanokwana kushanda kwepombi.Kuchinja kwakakura kwakadaro kunokonzeresa kukuvadza kune pombi system kunyanya sezvinotevera:
1. Kukonzera kudengenyeka kwakasimba kwepombi uye kubviswa kwejojo yepombi;
2. Ivhavha yakakuvadzwa, uye kudzvinyirira kwakakomba kwakanyanyisa kuita kuti pombi iparadze, uye kudzvinyirirwa kwemvura yemvura kunoderedzwa;
3. Pane zvinopesana, kana kudzvinyirira kwakanyanyisa, pombi ichaputsika, uye valve nekugadzirisa zvikamu zvichakuvadzwa;
4. Ita kuti pombi yemvura idzokere kumashure, inokanganisa midziyo kana mapaipi muimba yepombi, inokonzera zvakanyanya kuti pombi yepombi inyudzwe, inokonzera kukuvadzwa kwevanhu uye dzimwe njodzi huru, uye inokanganisa kugadzirwa nehupenyu.
Matanho ekudzivirira ekubvisa kana kuderedza sando yemvura
Kune matanho akawanda ekudzivirira pasando yemvura, asi matanho akasiyana anofanira kutorwa maererano nezvinokonzeresa nyundo yemvura.
1. Kuderedza kuyerera kwepombi yemvura kunogona kuderedza dzvinyiriro yesando yemvura kusvika kumwero wakati, asi kuchawedzera dhayamita yepombi yemvura uye kuwedzera mari yepurojekiti.Pakuisa mapaipi emvura, kufunga kunofanirwa kucherechedzwa kudzivirira humps kana shanduko huru pamateru.Kukura kwesando yemvura kana pombi yamira kunonyanya kuenderana nemusoro wejometri wekamuri yepombi.Iyo yakakwirira yemusoro wejometri, yakakura sando yemvura kana pombi yamiswa.Nokudaro, musoro wepombi unonzwisisika unofanirwa kusarudzwa maererano nemamiriro chaiwo emunharaunda.Mushure mekumisa pombi mutsaona, mirira kusvikira pombi kuseri kwevharuvhu yekutarisa yazadzwa nemvura isati yatanga pombi.Usanyatsovhura valve yekubuda yepombi yemvura paunotanga pombi, kana zvisina kudaro pachava nehombe huru yemvura.Dzakawanda dzetsaona huru dzesando dzemvura munzvimbo zhinji dzekupomba dzinoitika mumamiriro ezvinhu akadaro.
2. Seta mudziyo wekubvisa sando yemvura
(1) Kushandisa inogara ichimanikidza kudzora tekinoroji:
Sezvo kudzvinyirirwa kwepombi yemvura yepombi network inoshanduka nguva dzose nekuchinja kwemamiriro ekushanda, kuderera kwepasi kana kuwandisa kunowanzoitika panguva yekushanda kwegadziriro, iyo inotarisana nenyundo yemvura, zvichiita kuti kukuvadzwa kwepombi nemichina.Iyo otomatiki control system inogamuchirwa kudzora kudzvanywa kwepombi network.Iyo yekuona, mhinduro yekudzora kwekutanga, kumira uye nekukurumidza kugadzirisa kwepombi yemvura, kudzora kuyerera, uyezve kuchengetedza kudzvanywa pane imwe nhanho.Iyo yemvura yekumanikidza yepombi inogona kusetwa nekudzora iyo microcomputer kuchengetedza inogara ichimanikidza mvura yekupa uye kudzivirira yakawandisa kudzvanya kushanduka.Sando mukana wakaderedzwa.
(2) Isa nyundo yemvura inobvisa
Mudziyo uyu unonyanya kudzivirira sando yemvura kana pombi yamiswa.Iyo inowanzoiswa pedyo nepombi yekubuda yepombi yemvura.Iyo inoshandisa kudzvanywa kwepombi pachayo sesimba rekuona yakaderera-kudzvanya otomatiki chiito, ndiko kuti, kana kudzvanywa mupombi kwakadzikira pane yakatarwa yekudzivirira kukosha, iyo dhiraivha inongovhura uye inoburitsa mvura.Kudzora kudzvanyirira kudzikamisa kudzvanywa kwepombi dzenzvimbo uye kudzivirira kukanganisa kwesando yemvura pamidziyo nemapaipi.Kazhinji, zvinobvisa zvinogona kukamurwa kuva marudzi maviri: mechanical uye hydraulic.reset.
3) Isa chivharo chekuvhara chinononoka pane pombi yekubuda yepombi yemvura yakakura-caliber
Iyo inogona kunyatsobvisa nyundo yemvura kana pombi yakamira, asi nekuda kwekuti pane imwe chiyero chemvura yekudzokera shure kana vharuvhu ichiitwa, tsime rekusveta rinofanira kunge rine pombi inoputika.Kune marudzi maviri ekunonoka-kuvhara cheki mavharuvhu: sando mhando uye simba rekuchengetedza mhando.Rudzi urwu rwevhavha runogona kugadzirisa nguva yekuvhara yevhavha mukati mehumwe huwandu maererano nezvinodiwa.Kazhinji, 70% kusvika 80% yevhavha inovharwa mukati me3 kusvika 7 s mushure mekupera simba, uye nguva yekuvhara ye20% yasara kusvika 30% inogadziriswa zvichienderana nemamiriro epombi yemvura uye pombi, kazhinji. pakati pe10 kusvika ku30 s.Zvakakosha kucherechedza kuti cheki chekivhavha inononoka inovhara inoshanda zvakanyanya kana paine hump mupombi yekuvharisa sando yemvura.
(4) Gadzira shongwe yenzira imwe chete
Inovakwa padyo nechiteshi chekupomba kana panzvimbo yakakodzera yepombi, uye kureba kweimwe-nzira imwe shongwe yakadzikira pane yekumanikidza kwepombi ipapo.Kana kudzvanywa kwepombi kwakadzikira pane mwero wemvura mushongwe, shongwe yekukwirisa inozopa mvura kune pombi kudzivirira mbiru yemvura kuti isatyoke uye kudzivirira sando yemvura.Nekudaro, iyo inodzvinyirira mhedzisiro panyundo yemvura kunze kwepombi yekumisa nyundo yemvura, senge vharafu inovhara mvura sando, inogumira.Mukuwedzera, kushanda kwevhavha yenzira imwe chete inoshandiswa mune imwe nzira yekusvuta shongwe inofanira kuva yakavimbika zvachose.Kana vharuvhu yakundikana, inogona kutungamirira kunjodzi huru.
(5) Misa pombi yokunzvenga (vharuvhu) munzvimbo yekupomba
Apo pombi yepombi iri kushanda zvakajairika, cheki chevhavha yakavharwa nokuti mvura inodzvinyirira padivi remvura yepombi yakakwirira kudarika mvura yemvura padivi rekusveta.Apo kupera kwesimba kunongoerekana kwamisa pombi, kudzvinyirirwa kwepakubuda kwepombi kunodonha zvakanyanya, ukuwo kudzvinyirirwa padivi rekusveta kunokwira zvakanyanya.Pasi pekudzvanyirira uku kwakasiyana-siyana, iyo inopfupika yakakwira-kudzvanywa kwemvura mumvura yekusveta pombi hombe ndiyo inopfupikisa yakaderera-inomanikidza mvura inosundira kure cheki yevharuvhu ndiro uye inoyerera ichienda kune yekumanikidza mvura pombi huru, uye inowedzera kuderera kwemvura uko;kune rumwe rutivi, pombi yemvura Iyo nyundo yemvura inosimudzira padivi rekusveta inoderedzwa zvakare.Nenzira iyi, kukwira nekudonha kwesando yemvura kumativi ese echiteshi chekupomba kunodzorwa, nekudaro zvinobudirira kuderedza nekudzivirira njodzi dzesando dzemvura.
(6) Isai ma-multi-stage check valve
Mupombi refu yemvura, wedzera imwe kana mamwe mavharuvhu ekutarisa, patsanura pombi yemvura muzvikamu zvakawanda, uye isa cheki vharafu pachikamu chimwe nechimwe.Apo mvura iri mupombi yemvura inoyerera ichidzoka panguva yekugadzira sando yemvura, mavharuvhu echeki anovharwa mumwe pashure pomumwe kuti aparadzanise kuyerera kwemashure muzvikamu zvakawanda.Sezvo musoro we hydrostatic muchikamu chimwe nechimwe chepombi yemvura (kana kuti backflush flow section) iri diki, kuyerera kwemvura kunodzikira.Hammer Boost.Ichi chiyero chekudzivirira chinogona kushandiswa zvinobudirira mumamiriro ezvinhu apo iyo geometrical mvura inopa kukwirira musiyano yakakura;asi haigone kubvisa mukana wekuparadzaniswa kwembiru yemvura.Kukanganisa kwayo kukuru ndekwo: simba rekushandisa pombi yemvura rinowedzera panguva yekushanda kwemazuva ose, uye mari yemvura inowedzera.
(7) Otomatiki exhaust uye madhizaini ekupa mweya anoiswa panzvimbo yakakwirira yepombi kuderedza kukanganiswa kwesando yemvura papombi.
