Kuongororwa kwehunyanzvi hwehunyanzvi uye zvinhu zvakakosha zveinjiniya zvekuisa eccentric reducer musystem yepombi yemoto
1. Kugadziriswa kwezvimiro zvepombi yekuburitsa
Zvinoenderana nezvinodiwa zveGB50261 "Code for Construction and Acceptance of Automatic Sprinkler System":
Kugadziriswa kweChikamu Chepakati:
● Vharuvhu yekuchekerera (kana vharuvhu yekudzora pombi ine mabasa akawanda) inofanira kuiswa kudzivirira kudzokera shure kwenzira yemagetsi.
● Vharuvhu yekudzora inodiwa kuti idzore kuyerera kwemvura
● Kutarisa kaviri chiyero chekushanda kwesimba uye chiyero chesimba chepombi huru yekubuditsa yehurongwa
Zvinodiwa zveKutarisa Kumanikidzwa:
● Chiyero chekuyera kumanikidzwa chinofanira kunge chine mudziyo wekudzivirira (chinokurudzirwa kuti chivharo che diaphragm)
● Vharuvhu yepuragi yakaiswa pamberi pechinhu chinovhara kuti zvive nyore kugadzirisa
● Kuyera kwekumanikidza: 2.0-2.5 nguva yekumanikidzwa kwekushanda kwehurongwa
2. Gwaro rekuisa michina yekudzora mvura
Zvinodiwa pakutungamira:
● Mavharuvhu ekutarisa/mavharuvhu ekutonga ane mabasa akawanda anofanira kunge akanyatsoenderana negwara remvura inoyerera
● Kubatanidza flange kunokurudzirwa kuti ive nechokwadi chekuti kusimba
Mashoko ekuisa pressure gauge:
● Zvinhu zvisingapindi ngura (304 simbi isingatsvi kana mhangura) zvinofanira kushandiswa pakushandisa zvinhu zvinodzivirira ngura
● Kureba kwevharuvhu yepuragi kunofanira kuva 1.2-1.5m kubva pasi
3. Optimization scheme ye suction pombi system
Kugadziriswa kwemudziyo wefirita:
● Pombi yekusveta inofanira kunge ine sefa yebhasikiti (hukuru hwepore≤3mm)
● Sefa iyi inofanira kunge iine mudziyo wekutiza wekumanikidza
Yakagadzirirwa kuchengetedza zviri nyore:
● Sefa iyi inofanira kunge iine pombi yekubvisa tsvina uye nzira yekuchenesa nekukurumidza
● Kuvaka sefa inobviswa kunokurudzirwa
4. Matanho ekuchengetedza hunhu hwe hydraulic
Sarudzo yekuderedza zvinhu zvakasiyana-siyana:
● Zvinoderedza simba zvinomanikidzwa zvinofanira kushandiswa (zvichienderana neSH/T 3406)
● Kona yechinhu chinoderedza simba inofanira kuva ≤8° kudzivirira kuchinja kamwe kamwe kwesimba remunzvimbo yacho
Kugadzirisa Kuyerera Kwemvura:
● Kureba kwechikamu chepombi yakatwasuka isati yasvika uye yapera chinodzora kunofanira kunge kuri ≥ kashanu kupfuura dhayamita yepombi.
● Kuenzanisa kweCFD kunokurudzirwa kuti uone kugoverwa kwehuwandu hwemvura
5. Nzira dzekudzivirira pakuita basa
Kuongororwa kwekushushikana:
● Kuyedzwa kwekumanikidzwa kwesystem kunofanira kunge kwakapetwa ka1.5 kupfuura kumanikidzwa kwekushanda
● Nguva yekumirira haisi pasi pemaawa maviri
Nzira yeFlushing:
● Kubvisa tsvina kubva mumudziyo wemuchina (pickling passivation) kunofanira kuitwa usati waisa system.
● Mwero wekuyerera kwemvura unofanira kuva ≥ 1.5m/s
Maitiro Ekugamuchira:
● Kururama kwechiyero chekumanikidza hakufanirwe kunge kuri pasi pe1.6
● Kumanikidzwa kwemuchina wekusiyanisa firita kunofanira kuva ≤ 0.02MPa
6. Iyi sisitimu yekutsanangura zvinhu yakabatanidzwa mu "Technical Specifications for Fire Water Supply and Fire Hydrant Systems" GB50974, uye zvinokurudzirwa kuita ongororo yeHAZOP pamwe chete nemapurojekiti chaiwo, tichitarisa pane zvinotevera njodzi:
● Njodzi yekudzokera shure kwezvemukati memuviri nekuda kwekutadza kwemavharuvhu ekuongorora
● Njodzi yekukundikana kwemvura nekuda kwemafirita akavharika
● Njodzi yekuvhiyiwa zvakanyanya nekuda kwekutadza kwegeji yekumanikidza
● Njodzi yekuvhunduka kwemvura inokonzerwa nekusaiswa zvakanaka kwema reducers
Zvinokurudzirwa kushandisa chirongwa chekutarisa chedhijitari, kugadzirisa masensa ekumanikidza, mamonita ekuyerera kwemhepo uye analyzers ekudzungudza, uye kugadzira sisitimu yekutarisira kamuri repombi yemoto yakangwara kuti uwane kutarisa mamiriro ezvinhu panguva chaiyo uye yambiro yekukanganisa.
