Zida zoperekera madzi zopanda mphamvu

Mafotokozedwe Akatundu

Zida zoperekera madzi zopanda mphamvu ndi mtundu wa zida zachiwiri zopatsira madzi, zomwe zimalumikizidwa mwachindunji ndi netiweki yoperekera madzi mumsewu ndi gawo loperekera madzi, ndikupereka madzi motsatizana potengera kukakamizidwa kotsalira kwa chitoliro cha municipalities. maukonde kuonetsetsa kuti kukakamizidwa kwa ma network chitoliro cha matayala sikuchepera kuposa kuthamanga kwachitetezo (kutha kukhala 0 kukakamiza kwachibale, ndipo kutsika kwa 0, kumatchedwa kukakamiza koyipa).

Pachimake cha chitoliro network superimposed kuthamanga (palibe mphamvu zoipa) zipangizo madzi ndi mmene kupewa kuthamanga zoipa pa ntchito yachiwiri pressurized dongosolo madzi, kuthetsa zotsatira za ntchito unit pa maukonde mutauni chitoliro, ndi kukwaniritsa otetezeka, odalirika. , madzi okhazikika komanso osalekeza pa malo owonetsetsa kuti madzi akugwiritsa ntchito pafupi nawo sakukhudzidwa.

mfundo yogwirira ntchito

Non negative pressure water supply equipment imadziwikanso kuti pipe network superimposed pressure water supply equipment.Pali zida zamtundu wa tanki zopanda mphamvu zoperekera madzi komanso mtundu wamabokosi omwe siwovuta kuyika zida zamagetsi pamsika.

Matanki othamanga amtundu wamtundu wa non-negative pressure water supply amalumikizidwa mwachindunji ndi netiweki yamapaipi a municipalities, ndipo amapereka madzi motsatizana potengera kukakamizidwa kotsalira kwa netiweki yapaipi ya tauni.

Mfundo ntchito zipangizo

(1) Kuthamanga kwa madzi osinthasintha nthawi zonse: pamene kuchuluka kwa madzi amtundu wa mapaipi apakati ndi aakulu kuposa momwe amagwiritsira ntchito madzi, thanki yosasunthika yamtundu woipa wa zida zoperekera madzi zimapereka madzi pafupipafupi komanso kuthamanga kosalekeza.Panthawi imeneyi, madzi ena opanikizika amasungidwa mu thanki yosalekeza.

(2) Kuchotsa kupanikizika koipa: pamene kupanikizika kwa kugwirizana pakati pa ma netiweki amtundu wa chitoliro ndi thanki yosasunthika kumatsika chifukwa cha kuchuluka kwa madzi ogwiritsidwa ntchito ndi ogwiritsa ntchito, pamene kuthamanga kutsika pansi pa 0, kupanikizika koipa kumapangidwa. mu thanki yowonongeka, valavu yolowera ya vacuum suppressor idzatsegulidwa, ndipo mpweya udzalowa mu thanki yokhazikika.Panthawiyi, thanki yoyenda yokhazikika imakhala yofanana ndi thanki yamadzi yotseguka yokhala ndi madzi aulere.Kupanikizika kuli kofanana ndi mlengalenga, ndipo kupanikizika koipa kumachotsedwa.Pamene mlingo wa madzi akutsikira kwa mtengo anapereka, ndi madzi mlingo Mtsogoleri transmits ulamuliro chizindikiro kwa dongosolo ulamuliro mu pafupipafupi kutembenuka ulamuliro nduna kulamulira pressurizing wagawo kusiya ntchito ndi wosuta kusiya madzi;Madzi a wogwiritsa ntchito akachepa, kuchuluka kwa madzi mu thanki yosasunthika kumakwera, ndipo mpweya umatuluka mu valve yotulutsa mpweya wa vacuum suppressor.Kuthamanga kukabwerera mwakale, makina osindikizira ayambiranso kuti abwezeretsenso madzi.

(3) Madzi odulidwa ndi kutseka ntchito: pamene maukonde a chitoliro cha tauniyo atadulidwa, gawo lopondereza lidzasiya kugwira ntchito motsogozedwa ndi wolamulira wamadzimadzi.Pambuyo ma municipalities chitoliro maukonde madzi abwezeretsedwa .
