Iindaba - Inkcazo ye-eccentric reducers kwiimpompo zomlilo

Uhlalutyo lweenkcukacha zobugcisa kunye neengongoma eziphambili zobunjineli zokufakelwa kwe-eccentric reducer kwinkqubo yempompo yomlilo

1.Inkcazo yoqwalaselo lwamacandelo ombhobho wokuphuma

Ngokwemimiselo enyanzelekileyo ye-GB50261 "iKhowudi yoLwakhiwo kunye noKwamkelwa kweNkqubo yokutshiza ye-Automatic":
Uqwalaselo lwecandelo elingundoqo:
● Ivalve yokutshekisha (okanye ivalve yokulawula impompo enemisebenzi emininzi) kufuneka ifakwe ukuthintela ukubuya ngasemva kwendawo ephakathi
● Ivalve yokulawula iyafuneka kulawulo lokuhamba
● Ukubeka iliso kabini kwi-gauge ye-pressure gauge kunye ne-pressure gauge yombhobho oyintloko wokuphuma kwenkqubo
IiMfuno zokuJonga uxinzelelo:
● Igeyiji yoxinzelelo kufuneka ixhotyiswe ngesixhobo sokukhusela (i-diaphragm buffer iyacetyiswa)
● Ivalve yokuplaga efakwe phambi kwesixhobo sokukhusela ukuze sigcinwe lula
● Uluhlu lokulinganisa uxinzelelo: 2.0-2.5 amaxesha oxinzelelo olusebenzayo lwenkqubo

2. Izikhokelo zokufakela izixhobo zokulawula ulwelo

IiMfuno zendlela:
● Iivalvu zokukhangela/iivalvu zokulawula imisebenzi emininzi kufuneka zihambelane ngokungqongqo necala lokuhamba kwamanzi
● Uxhulumaniso lwe-Flange luyacetyiswa ukuqinisekisa ukuqina
Iinkcukacha zofakelo lwegeyiji yoxinzelelo:
● Izinto ezikwaziyo ukutyiwa (304 intsimbi engatyiwayo okanye ialloyi yobhedu) kufuneka zisetyenziswe kwizixhobo ezikhuselayo.
● Ubude bokusebenza kwevalve yeplagi kufuneka bube yi-1.2-1.5m ukusuka emhlabeni

3.Iskim sokuphucula inkqubo yombhobho wokufunxa

Hluza ubumbeko lwesixhobo:
● Umbhobho wokufunxa kufuneka uxhotyiswe ngesihluzo sebhaskithi (ubungakanani bepore≤3mm)
● Isihluzi kufuneka sixhotyiswe ngesixhobo sokulumkisa ngoxinzelelo olwahlukileyo
Yenzelwe ukugcinwa lula:
● Isihluzi kufuneka sixhotyiswe ngombhobho odlulayo kunye nojongano olukhawulezayo lokucoca
● Ulwakhiwo lwesihluzo esinokususwa kuyacetyiswa

4.Imilinganiselo yokukhusela iimpawu ze-hydraulic

Ukukhetha isinciphisi se-Eccentric:
● Izinciphisi ezicinezelweyo ezisemgangathweni kufuneka zisetyenziswe (ngokwe SH/T 3406)
● I-angle yokunciphisa kufuneka ibe ngu-≤8 ° ukukhusela utshintsho ngokukhawuleza ekuchaseni kwendawo
UkuPhuculwa kokuHamba:
● Ubude becandelo lombhobho ochanekileyo ngaphambi nangemva kokuba umnciphisi kufuneka abe ≥ amaxesha ama-5 ububanzi bombhobho
● Ukulinganisa kweCFD kuyacetyiswa ukuqinisekisa ukuhanjiswa kwesantya sokuhamba

5.Imiqathango yokuphunyezwa kweprojekthi

Uvavanyo loxinzelelo:
● Uvavanyo loxinzelelo lwenkqubo kufuneka lube ngamaxesha angama-1.5 kuxinzelelo lokusebenza
● Ixesha lokubamba alikho ngaphantsi kweeyure ezi-2
Inkqubo yokugungxulwa:
● I-Pickling passivation kufuneka yenziwe phambi kofakelo lwesixokelelwano
● Isantya sokugungxulwa kufuneka sibe ≥ 1.5m/s
Iinqobo zokwamkelwa:
● Inqanaba lokuchaneka kwe-gauge yoxinzelelo akufanele libe ngaphantsi kwe-1.6
● Uxinzelelo oluhlukileyo lokucoca kufuneka lube ≤ 0.02MPa

I-6.Le nkqubo yenkcazo ifakwe kwi-"Technical Specifications for Fire Water Supply and Fire Hydrant Systems" GB50974, kwaye kucetyiswa ukuba kwenziwe uhlalutyo lwe-HAZOP ngokudibanisa neeprojekthi ezithile, kugxininise kula manqaku omngcipheko alandelayo:

● Umngcipheko wokubuyela umva kwemidiya ngenxa yokusilela kweevalvu zokutshekisha
● Umngcipheko wokungaphumeleli konikezelo lwamanzi ngenxa yezihluzo ezivalekileyo
● Umngcipheko wokusebenza koxinzelelo olugqithisileyo ngenxa yokusilela kwegeyiji yoxinzelelo
● Umngcipheko wokothuka kwehydraulic obangelwa kukufakwa ngokungafanelekanga kwezinciphisi

Kunconywa ukuba uthabathe iskimu sokubeka iliso sedijithali, uqulunqe izinzwa zoxinzelelo, iimonitha zokuhamba kunye nabahlalutyi be-vibration, kunye nokuseka inkqubo yokulawula impompo yomlilo ehlakaniphile ukufezekisa ukubeka iliso kwexesha langempela kunye nesilumkiso sephutha.
