Ukuhlaziywa kwezincazelo zobuchwepheshe kanye namaphuzu abalulekile obunjiniyela bokufakwa kwe-eccentric reducer ohlelweni lwephampu yomlilo
1. Ukucaciswa kokucushwa kwezingxenye zepayipi lokukhipha
Ngokwemibandela eyimpoqo ye-GB50261 ethi "Ikhodi Yokwakhiwa Nokwamukelwa Kohlelo Lokufafaza Okuzenzakalelayo":
Ukucushwa Kwengxenye Eyinhloko:
● Ivalvu yokuhlola (noma ivalvu yokulawula iphampu enemisebenzi eminingi) kumele ifakwe ukuze kuvinjelwe ukugeleza kwamanzi emuva kwe-medium
● I-valve yokulawula iyadingeka ukuze kulawulwe ukugeleza kwamanzi
● Ukuqapha kabili igeyiji yokucindezela okusebenzayo kanye negeyiji yokucindezela yepayipi eliyinhloko lokukhipha uhlelo
Izidingo Zokuqapha Ukucindezeleka:
● Igeyiji yokucindezela kufanele ifakwe idivayisi ye-buffer (kunconywa i-diaphragm buffer)
● I-plug valve ifakwe phambi kwedivayisi ye-buffer ukuze kube lula ukuyilungisa
● Ububanzi besilinganiso sokucindezela: izikhathi ezingu-2.0-2.5 kunengcindezi yokusebenza yesistimu
2. Iziqondiso zokufakwa kwamadivayisi okulawula uketshezi
Izidingo Zokuqondisa:
● Amavalvu okuhlola/amavalvu okulawula imisebenzi eminingi kufanele ahambisane ngokuqinile nendlela amanzi ageleza ngayo
● Kunconywa ukuxhuma i-flange ukuqinisekisa ukuqina
Imininingwane yokufaka i-Pressure gauge:
● Izinto ezingamelani nokugqwala (insimbi engagqwali engu-304 noma i-alloy yethusi) kufanele zisetshenziswe kumadivayisi okuvimba
● Ukuphakama kokusebenza kwevalvu yepulaki kufanele kube yi-1.2-1.5m ukusuka phansi
3. Uhlelo lokwenza ngcono uhlelo lwepayipi lokumunca
Ukucushwa kwedivayisi yokuhlunga:
● Ipayipi lokumunca kufanele lifakwe isihlungi sebhasikidi (usayizi wembobo≤3mm)
● Isihlungi kufanele sibe nedivayisi ye-alamu yokucindezela okuhlukile
Yakhelwe ukuze kube lula ukuyinakekela:
● Isihlungi kufanele sibe nepayipi elidlulayo kanye ne-interface yokuhlanza esheshayo
● Kunconywa ukwakhiwa kwesihlungi esisuswayo
4. Izinyathelo zokuvikela izici ze-hydraulic
Ukukhetha i-Eccentric reducer:
● Kumelwe kusetshenziswe izinciphisi ezijwayelekile ezicindezelwe (ngokusho kwe-SH/T 3406)
● I-engeli yesinciphisi kufanele ibe ngu-≤8° ukuvimbela izinguquko ezisheshayo ekumelaneni kwendawo
Ukuthuthukiswa Kokugeleza:
● Ubude besigaba sepayipi eliqondile ngaphambi nangemva kwesinciphisi kufanele bube ≥ izikhathi ezi-5 ububanzi bepayipi
● Kunconywa ukulingisa kwe-CFD ukuqinisekisa ukusatshalaliswa kwezinga lokugeleza
5. Izinyathelo zokuphepha zokuqaliswa kwephrojekthi
Ukuhlolwa kokucindezeleka:
● Ukuhlolwa kwengcindezi yesistimu kufanele kube yingcindezi yokusebenza ephindwe ka-1.5
● Isikhathi sokulinda asingaphansi kwamahora ama-2
Iphrothokholi Yokuhlanza:
● Ukususwa kwe-pickling kufanele kwenziwe ngaphambi kokufakwa kwesistimu
● Izinga lokugeleza kokuhlanza kufanele libe ngu-≥ 1.5m/s
Izindlela Zokwamukela:
● Izinga lokunemba kwesilinganiso sokucindezela akufanele libe ngaphansi kuka-1.6
● Ukucindezela komehluko wesihlungi kufanele kube ngu-≤ 0.02MPa
6. Lolu hlelo lokucacisa lufakiwe ku-"Technical Specifications for Fire Water Supply and Fire Hydrant Systems" GB50974, futhi kunconywa ukuthi kwenziwe ukuhlaziywa kwe-HAZOP kuhlanganiswe namaphrojekthi athile, kugxilwe kula maphuzu alandelayo engozi:
● Ingozi yokugeleza kwemidiya emuva ngenxa yokwehluleka kwama-valve okuhlola
● Ingozi yokwehluleka kokunikezwa kwamanzi ngenxa yezihlungi ezivalekile
● Ingozi yokusebenza ngokweqile ngenxa yokwehluleka kwesilinganiso sokucindezela
● Ingozi yokushaqeka kwe-hydraulic okubangelwa ukufakwa okungafanele kwama-reducer
Kunconywa ukuthi kusetshenziswe uhlelo lokuqapha lwedijithali, kulungiselelwe izinzwa zokucindezela, iziqaphi zokugeleza kanye nezihlaziyi zokudlidliza, futhi kusungulwe uhlelo lokuphatha igumbi lomlilo oluhlakaniphile ukuze kufezwe ukuqapha isimo ngesikhathi sangempela kanye nesixwayiso samaphutha.
