Intshayelelo kuMbhobho weMpompi: Ukuguqula iNdlela eFanelekileyo yoKwakha
Umbhobho wempompo, owaziwa ngokuba ngumbhobho wempompo wekhonkrithi, sisixhobo soguqulo soomatshini bobunjineli obuphucula ngokubonakalayo ukusebenza kakuhle kolwakhiwo lwekhonkrithi. Olu didi lutsha lwezixhobo zoomatshini bokwakha luza kunye noomatshini bokwakha bekhonkrithi, nto leyo eyenza ibe yinxalenye ebalulekileyo yayo nayiphi na iprojekthi yokwakha yale mihla.
Imibhobho yempompo yamanzi idla ngokubizwa ngokuba yimibhobho yempompo yomgangatho, equka impompo yomgangatho imibhobho ethe tye kunye nengqiniba yempompo yomgangatho. Le mibhobho ikakhulu yenziwe 20 # carbon steel, eyaziwa ngokuba Q235B. Inkqubo yokuvelisa ibandakanya iiflange ze-welding zemibhobho ezingenamthungo kunye nokuphosa, kulandelwa ukudibanisa kombhobho. Obu buchule bobugcisa buqinisekisa ukuqina kunye nokuthembeka kwetyhubhu yempompo.
Ngokweemfuno ezahlukeneyo zokusebenza, imibhobho yempompo yahlulahlulwe ibe nguxinzelelo oluphantsi, uxinzelelo oluphezulu kunye noxinzelelo oluphezulu. Umzekelo, kukho iintlobo ezininzi zempompo yomhlaba emibhobho ethe ngqo efana ne-DN80, DN100, DN125, kunye ne-DN150. Iimodeli ze-DN80 kunye ne-DN100 ziqhele ukusetyenziswa kwiimpompo zodaka kwaye zihlala zibizwa ngokuba yimibhobho yempompo yodaka okanye imibhobho yempompo yodaka. Kwelinye icala, i-DN125 yeyona isetyenziswa ngokuqhelekileyo umbhobho wempompo yekhonkrithi kwizicelo zoxinzelelo oluphantsi.
Ububanzi bangaphandle bepayipi ye-DN125 yi-133mm, kwaye ubukhulu bomzimba wombhobho ngu-4.5-5mm. Inkqubo ye-welding ezenzekelayo ye-25mm ye-flange esisigxina yamkelwa ukuqinisekisa umgangatho kunye nokunyaniseka kombhobho. Le mibhobho yempompo yomgangatho ilungele ukubekwa kwekhonkrithi ephantsi kunye nezinye izicelo zoxinzelelo oluqhelekileyo.
Ukusetyenziswa koxinzelelo oluphezulu kunye ne-ultra-high, ububanzi bangaphandle bombhobho wempompo bunyuswa ukuya kwi-140mm. Ubunzima bodonga lwemibhobho yoxinzelelo oluphezulu luyi-6mm, kwaye ubukhulu bodonga lwemibhobho ye-ultra-high-pressure yi-8mm okanye i-10mm. Ixhotyiswe ngeeflange zobuso obuyi-175 mm okanye i-194 mm kunye neeflange ezinobumba, le mibhobho yenzelwe ukumelana neemeko zokusebenza ezinzima.
Ukongeza kumanqanaba ahlukeneyo oxinzelelo, i-tubing yepompo ifumaneka ngobude obuhlukeneyo, kubandakanywa i-0.3m, 0.5m, 1m, 2m kunye ne-3m. Ubude bunokwenziwa ngokwemfuneko ukuhlangabezana neemfuno ezithile zeprojekthi.
Ngokubanzi, imibhobho yempompo idlala indima ebalulekileyo ekuhanjisweni ngokukhawuleza nangokufanelekileyo kwekhonkrithi kwiiprojekthi zokwakha. Ulwakhiwo lwayo olomeleleyo kunye neenketho zoxinzelelo ezahlukeneyo zenza ukuba ibe yinto eyimfuneko kuzo zonke iintlobo zezicelo zokumpompa zekhonkrithi. Ngombhobho wempompo, ukusebenza kakuhle kolwakhiwo kuye kwandiswa ukuya kumanqanaba angazange abonwe ngaphambili, kuvula indlela yenkqubo yokwakha ekhawulezayo, eneendleko ezingaphezulu.
