Uhlalutyo lweenkcukacha zobugcisa kunye neendawo eziphambili zobunjineli zokufakela i-eccentric reducer kwinkqubo yepompo yomlilo
1. Inkcazo yoqwalaselo lwezixhobo zepayipi yokuphuma
Ngokwemigaqo enyanzelekileyo ye-GB50261 ethi "Umgaqo woKwakha noKwamkelwa kweNkqubo yokuSprinkler eZenzekelayo":
Uqwalaselo lweCandelo eliPhambili:
● Kufuneka kufakwe ivalvu yokujonga (okanye ivalvu yokulawula ipompo enemisebenzi emininzi) ukuthintela ukubuya kwamanzi kwi-medium
● Ivalvu yokulawula iyadingeka ukuze kulawulwe ukuhamba kwamanzi
● Ukujonga kabini igeyiji yoxinzelelo olusebenzayo kunye negeyiji yoxinzelelo yombhobho ophambili wokukhupha wenkqubo
Iimfuneko zokujonga uxinzelelo:
● Igeyiji yoxinzelelo kufuneka ixhotyiswe ngesixhobo sokukhusela (kucetyiswa ukuba i-diaphragm buffer)
● Ivalvu yeplagi ifakwe phambi kwesixhobo se-buffer ukuze kube lula ukuyilungisa
● Uluhlu lokulinganisa uxinzelelo: 2.0-2.5 amaxesha uxinzelelo olusebenzayo lwenkqubo
2. Izikhokelo zokufakelwa kwezixhobo zokulawula ulwelo
Iimfuno zoBuchule:
● Iivalvu zokujonga/iivalvu zokulawula imisebenzi emininzi mazihambelane ngqo necala lokuhamba kwamanzi
● Uqhagamshelo lweFlange luyacetyiswa ukuqinisekisa ukuqina
Iinkcukacha zokufakelwa kwegeyiji yoxinzelelo:
● Izinto ezimelana nokugqwala (intsimbi engagqwaliyo engama-304 okanye i-alloy yobhedu) mazisetyenziswe kwizixhobo ze-buffer
● Ukuphakama kokusebenza kwevalvu yeplagi kufuneka kube yi-1.2-1.5m ukusuka emhlabeni
3. Inkqubo yokwenza ngcono inkqubo yombhobho wokufunxa
Uqwalaselo lwesixhobo sesihluzi:
● Umbhobho wokufunxa kufuneka uxhotyiswe ngesihluzo sebhasikithi (ubukhulu bembobo≤3mm)
● Isihluzo kufuneka sixhotyiswe ngesixhobo sokulumkisa uxinzelelo oluhlukeneyo
Yenzelwe ukuba kube lula ukuyigcina ikwimeko entle:
● Isihluzo kufuneka sixhotyiswe ngepayipi yokudlula kunye nomgca wokucoca ngokukhawuleza
● Kucetyiswa ukwakhiwa kwesihluzo esisuswayo
4. Amanyathelo okukhusela iimpawu ze-hydraulic
Ukukhetha i-Eccentric reducer:
● Kufuneka kusetyenziswe izinciphisi ezixinzelelweyo eziqhelekileyo (ngokwe-SH/T 3406)
● I-engile yesinciphisi kufuneka ibe yi-≤8° ukuthintela utshintsho olukhawulezileyo kukumelana kwendawo
Ukulungiswa Kokuhamba Komsinga:
● Ubude becandelo lombhobho othe tye ngaphambi nasemva komnciphisi kufuneka bube ≥ ngokuphindwe kahlanu ubukhulu bombhobho
● Kucetyiswa ukuba kwenziwe ukulinganisa kwe-CFD ukuqinisekisa ukusasazwa kwesantya sokuhamba kwamanzi
5. Amanyathelo okhuseleko ekuphunyezweni kweprojekthi
Uvavanyo loxinzelelo:
● Uvavanyo loxinzelelo lwenkqubo kufuneka lube luphindwe kayi-1.5 kunoxinzelelo olusebenzayo
● Ixesha lokubamba alikho ngaphantsi kweeyure ezi-2
Iprotokholi yokuFusha:
● Ukucoca nge-pickling kufuneka kwenziwe ngaphambi kokuba kufakwe inkqubo
● Isantya sokuhamba kwamanzi kufuneka sibe yi-≥ 1.5m/s
Iikhrayitheriya zoKwamkelwa:
● Inqanaba lokuchaneka kwegeyiji yoxinzelelo akufuneki libe ngaphantsi kwe-1.6
● Uxinzelelo lomahluko wesihluzo kufuneka lube yi-≤ 0.02MPa
6. Le nkqubo yeenkcukacha ifakiwe kwi-"Technical Specifications for Fire Water Supply and Fire Hydrant Systems" GB50974, kwaye kuyacetyiswa ukuba kwenziwe uhlalutyo lwe-HAZOP kunye neeprojekthi ezithile, kugxilwe kula manqaku omngcipheko alandelayo:
● Umngcipheko wokubuyela umva kwemidiya ngenxa yokungasebenzi kakuhle kweevalvu zokujonga
● Ingozi yokungasebenzi kwamanzi ngenxa yezihluzo ezivalekileyo
● Umngcipheko wokusebenza ngokugqithisileyo ngenxa yokungasebenzi kakuhle kwegeyiji yoxinzelelo
● Umngcipheko wokothuka ngamanzi amdaka okubangelwa kukufakelwa okungafanelekanga kwee-reducers
Kucetyiswa ukuba kusetyenziswe inkqubo yokubeka esweni yedijithali, kumiselwe izinzwa zoxinzelelo, iimonitha zokuhamba kunye nezihlalutyi zokungcangcazela, kwaye kusekwe inkqubo yolawulo lwegumbi lepompo yomlilo ekrelekrele ukuze kufezekiswe ukujonga imeko ngexesha langempela kunye nesilumkiso sempazamo.
