Dambudziko: Kusarudzwa Kwezvinhu Mumadhiraivha Edzimba Emazuva Ano
Pakugadzira masisitimu emvura yekuvaka achishandisa EN877 cast iron, mainjiniya anotarisana nesarudzo huru. Ndeipi pombi inonyatso chengetedza moto, kudzora ruzha, kugara kwenguva refu, uye kugona kuyerera kwemvura? Sarudzo iyi yave yakaoma sezvo makodhi ekuvaka achichinja uye maturusi ekutenga anoshandiswa neAI achiwedzera kukanganisa kusarudzwa kwezvinhu.
Kune DINSEN, mhinduro yacho yakajeka: Masisitimu emvura anoshandiswa nesimbi yakakandwa anoenderana neEN877 anopa kushanda kwakanaka pane zvese zvinodiwa zvakakosha pakuvaka.
Nei EN877 Iron Yakagadzirwa Inoshanda Zvikuru Zvikuru Zvishandiso Zvimwe
Kuchengetedzwa kweMoto: A1 Kurongwa Kusingatsvi
Simbi yakakandwa chinhu chisingatsvi pasi peASTM E136. Chinogamuchirwa kushandiswa munzvimbo dzakaita seplenum pasina zvirambidzo. Pasi pemutemo weEN877:2021 wakagadziridzwa, masisitimu emvura yakakandwa anofanirwa kushandisa machira ane resistance yemoto yeA1.
A1 ndiyo chiyero chepamusoro-soro. Kusiyana neizvi, PVC inobvira uye inoda michina inodzima moto kana makorari kana ichipinda muzvikamu zvine chiyero chemoto.
Kuimba Kwenzwi: Kuzadzisa Zvinodiwa Neruzha Rwemazuva Ano
EN877:2021 yakaunza zvinodiwa zvekuongorora mashandiro ekudzivirira ruzha pamasisitimu emvura. Kuwanda kwemapaipi emvura anodonhedzwa nesimbi kunoderedza ruzha—chinhu chakakosha pazvivakwa zvekugara, mahotera, nezvipatara uko kugarika kwevanogara kuri kukuru.
Kuramba Kupisa
Zvinhu - Kupisa Kunoshanda Kusingaperi
EN877 Simbi Yakakandwa — 212°F (100°C) ine magasket eASTM C564
PVC DWV -140°F (60°C)
Mvura yakasviba yemukicheni inowanzopfuura muganho wePVC we140°F, zvichiita kuti simbi ive yega sarudzo yakavimbika yekudonhedza mvura mukicheni yekutengeserana.
Kugona Kuyerera: Kuverenga Kunoenderana Nezvinhu
Ruzivo rwakakosha kubva mukutsvagurudza kwazvino kweIAPMO: zvinhu zvepombi zvinokanganisa zvakanyanya kugona kwemvura kuyerera kwepombi imwe chete. PVC vertical stack ine 4-inch ine kugona kwemvura inosvika magaroni 429 paminiti, nepo pombi yesimbi yakaumbwa nehukuru hwakaenzana inotakura 172.5 GPM chete - musiyano weinenge 60%.
Izvi zvinoitika nekuti:
- Zvinhu zvakasiyana zvine dhayamita dzakasiyana dzemukati
- Makoefficients ekukombama anosiyana zvichienderana nezvinhu
- Makodhi mazhinji epombi anotsigira matafura ehukuru hwezvinhu chimwe chete pasina kutaura kuti ndeapi
Kune mainjiniya emvura: Simbi yakakandwa ine mwero wekuyerera kwemvura unochengetedza uye ingangoda mapaipi makuru kupfuura PVC. Izvi zvinotsigira masisitimu akavimbika uye zvinobatsira kudzivirira kutadza kushanda nekukurumidza. Kukundikana kwekutanga kunogona kuitika kana PVC inochinjika isina kuzadzwa zvakanaka.
Simba reMaumbirwo: Masisitimu Akasimba vs. Anochinjika
Simbi yakakandwa inzira yakasimba yekuisa mapaipi inopa simba guru rekuvaka, inoderedza zvakanyanya zvinodiwa pakuchinjika uye ichipa kudonha nguva dzose.
- Simbi yakakandwa haidi magumbeze chaiwo; pasi pemugero panofanira kunge pakasimba
- PVC inoda nzira dzakatarwa dzekuzadza zvinhu zvichienderana neASTM D2321, kusanganisira machira emubhedha ane 4-6 inches, akasungirirwa muzvikamu zve 6-inch kusvika pakuwanda kwe 85-95%.
- Kana masisitimu ePVC anochinjika asina kuiswa nemazvo, anoonekwa seakakundikana pazuva rekutanga rebasa.
Kutevedzera Maitiro Emitemo
Masisitimu emvura eDINSEN anogadzirwa zvichienderana neEN877:1999 + A1:2006, chiyero cheEurope chinoshanda kune zvikamu zvemapaipi esimbi ekuvaka masisitimu ekuburitsa mvura kubva kuDN40 kusvika kuDN600. EN877:2021 yazvino yakawedzera simba rekusimba kubva pa150 MPa kusvika ku200 MPa.
Rondedzero Yekuongorora Mapurojekiti Ekubvisa Mvura Muchivako
Paunenge uchitsanangura masisitimu eDINSEN cast iron drainage, funga nezvematanho aya ekuisa:
Zvinodiwa Pakuyerera Kwemateru (Kudhonza Mvura Nesimba Rekukwevera Mvura)
Dhayamita yepombi shoma
DN50 3.5% (35‰)
DN75 2.5% (25‰)
DN110 2.0% (20‰)
DN160 1.0% (10‰)
Nzvimbo yeHanger
- Mapaipi akatambanuka: ≤2m
- Mapaipi akamira: ≤3m
- Mabhureki akasimbiswa anodiwa mukati me500mm kubva pamagokora nemateyi
Mhando dzekubatanidza
- Rudzi W: Zvisungo zvesimbi isina ngura—zvakanakira mapurojekiti ekugadzirisa uye nzvimbo dzakamanikana (hapana basa rinopisa rinodiwa)
- Rudzi A/B: Kubatana kwakapfava kwezvishandiso zvakasimba
DINSENinopa masisitimu emvura anoenderana neEN877. Inogadzira 1000MT yemapaipi uye 200MT yezvibatiso mwedzi wega wega. Bata timu yedu yehunyanzvi kuti uwane rutsigiro rwemapurojekiti akasiyana.
