Ukuhlaziywa kwezicaciso zobuchwepheshe kanye namaphoyinti abalulekile wobunjiniyela wokufakwa kwe-eccentric reducer ohlelweni lwephampu yomlilo
1.Ukucaciswa kokucushwa kwezingxenye zamapayipi okuphumayo
Ngokuya ngezinhlinzeko eziyisibopho ze-GB50261 "Ikhodi Yokwakhiwa Nokwamukelwa Kwesistimu Yokufafaza Okuzenzakalelayo":
Ukucushwa Kwengxenye Eyinhloko:
● I-valve yokuhlola (noma i-valve yokulawula iphampu enemisebenzi eminingi) kufanele ifakwe ukuze kuvinjelwe ukugeleza emuva kwe-medium
● Ivalvu yokulawula iyadingeka ukuze kulawulwe ukugeleza
● Ukuqapha kabili kwegeji yengcindezi yokusebenza kanye negeji yokucindezela yepayipi eliphumayo elikhulu lesistimu
Izidingo Zokuqapha Ingcindezi:
● Igeyiji yokucindezela kufanele ifakwe idivayisi yebhafa (kunconywa i-diaphragm buffer)
● I-valve yokuxhuma efakwe ngaphambi kwedivayisi ye-buffer ukuze ilungiswe kalula
● Ububanzi begeji yokucindezela: izikhathi ezingu-2.0-2.5 zokucindezela kokusebenza kwesistimu
2. Imihlahlandlela yokufakwa kwamadivaysi okulawula uketshezi
Izidingo Zokuqondisa:
● Amavalvu okuhlola/amavalvu okulawula imisebenzi eminingi kufanele ahambisane ngokuqinile nesiqondiso sokugeleza kwamanzi
● Uxhumano lwe-flange luyanconywa ukuze kuqinisekiswe ukuqina
Imininingwane yokufaka isikali somfutho:
● Izinto ezikwazi ukumelana nokugqwala (304 insimbi engagqwali noma ingxubevange yethusi) kufanele zisetshenziselwe izisetshenziswa zebhafa.
● Ubude bokusebenza bevalve yepulaki kufanele bube ngu-1.2-1.5m ukusuka phansi
3.Isikimu sokwenza ngcono sohlelo lwamapayipi okumunca
Isihlungi sokucushwa kwedivayisi:
● Ipayipi elimunca kufanele lifakwe isihlungi sikabhasikidi (usayizi wembotshana≤3mm)
● Isihlungi kufanele sifakwe idivayisi ye-alamu yokucindezela okuhlukile
Idizayinelwe ukuthi ilungiswe kalula:
● Isihlungi kufanele sifakwe ipayipi lokudlula kanye nesixhumi esibonakalayo sokuhlanza ngokushesha
● Kunconywa ukwakhiwa kwesihlungi esingahlukaniseki
4.Vikela izinyathelo zezimpawu ze-hydraulic
Ukukhetha isinciphisi se-Eccentric:
● Izinciphisi ezicindezelwe ezijwayelekile kufanele zisetshenziswe (ngokuya nge-SH/T 3406)
● I-engeli yesinciphisi kufanele ibe ngu-≤8° ukuze kuvinjelwe izinguquko ezingazelelwe ekuphikiseni kwendawo
Ukuthuthukisa Ukugeleza:
● Ubude besigaba sepayipi eliqondile ngaphambi nangemva kokunciphisa kufanele kube ≥ izikhathi ezingu-5 ububanzi bepayipi
● Ukulingiswa kwe-CFD kuyanconywa ukuze kuqinisekiswe ukusatshalaliswa kwezinga lokugeleza
5.Izinyathelo zokuphepha zokuqaliswa kwephrojekthi
Ukuhlolwa kwengcindezi:
● Ukuhlolwa kwengcindezi yesistimu kufanele kube izikhathi ezingu-1.5 kunokucindezela kokusebenza
● Isikhathi sokubamba asikho ngaphansi kwamahora ama-2
I-Flushing Protocol:
● I-Pickling passivation kufanele yenziwe ngaphambi kokufaka uhlelo
● Izinga lokugeleza kwamanzi kufanele libe ngu-≥ 1.5m/s
Imibandela yokwamukela:
● Izinga lokunemba legeji yokucindezela akufanele libe ngaphansi kuka-1.6
● Ingcindezi yokuhlukanisa isihlungi kufanele ibe ngu-≤ 0.02MPa
6.Lolu hlelo lokucaciswa lufakwe "Ezicacisweni Zobuchwepheshe Zokuhlinzeka Ngamanzi Omlilo kanye Nezinhlelo Zokukhipha Umlilo" GB50974, futhi kunconywa ukwenza ukuhlaziywa kwe-HAZOP kuhlanganiswe namaphrojekthi athile, kugxilwe kulawa maphuzu obungozi alandelayo:
● Ingozi yokubuyela emuva kwemidiya ngenxa yokwehluleka kwamavalvu okuhlola
● Ingozi yokwehluleka kokunikezwa kwamanzi ngenxa yezihlungi ezivalekile
● Ingozi yokusebenza kokucindezeleka ngokweqile ngenxa yokwehluleka kwegeji yokucindezela
● Ingozi ye-hydraulic shock ebangelwa ukufakwa okungalungile kwezinciphisi
Kunconywa ukuthi kwamukele isikimu sokuqapha sedijithali, ulungiselele izinzwa zokucindezela, iziqaphi zokugeleza nezihlaziyo zokudlidliza, futhi usungule uhlelo lokulawula igumbi lephampu yomlilo elihlakaniphile ukuze kuzuzwe ukuqapha isimo sesikhathi sangempela kanye nesixwayiso samaphutha.
