Ipayipi lenqubo lidlala indima ebalulekile emayunithi okukhiqiza amandla, amakhemikhali, amakhemikhali kaphethroli, insimbi kanye nezinye izingxenye zokukhiqiza. Inqubo yokufaka ihlobene ngqo nekhwalithi yephrojekthi kanye nomthamo wokuphepha. Ekufakweni kwepayipi lenqubo, ubuchwepheshe bepayipi lenqubo buyiphrojekthi enezidingo zobuchwepheshe eziphezulu kanye nenqubo yokufaka eyinkimbinkimbi kakhulu. Ikhwalithi yokufaka ipayipi ithinta ngqo ikhwalithi yenqubo yokuthutha, ayithinti nje kuphela inqubo yokuthutha umkhiqizo, kodwa futhi idlala indima enkulu emsebenzini. Ngakho-ke, ekufakweni kwepayipi lenqubo yangempela, ikhwalithi yokufaka kumele ilawulwe. Leli phepha lixoxa futhi lichaza ukulawulwa kokufakwa kwepayipi kanye nezinkinga okumele zinakwe emkhakheni wokufakwa kwepayipi eShayina.
Ipayipi lomoya elicindezelwe
Ukulawulwa kwekhwalithi kokufakwa kwephayiphi yenqubo eShayina kuhlanganisa kakhulu: isigaba sokulungiselela ukwakhiwa, isigaba sokwakha, isigaba sokuhlola, ukuhlolwa kokuhlolwa, isigaba sokuhlanza amaphayiphi kanye nesigaba sokuhlanza. Njengoba izidingo zobuchwepheshe zikhula, ekwakheni kwangempela, kumelwe silungiselele, sifake, silawule futhi silwe nokugqwala ngokwesimo sangempela.
1. Nquma uhlelo lokufakwa kwepayipi lenqubo
Ngaphambi kokuba kunqunywe ukufakwa kwepayipi lenqubo, inani eliyisisekelo lokufakwa kwephrojekthi kanye nokwakhiwa kumele lichazwe ngokwezimo zokufakwa kanye nendawo yokwakha kanye nomklamo wokwakha. Izinsizakusebenza eziyinhloko zabantu kanye nezinto zokwakha zokwakhiwa zizoqinisekiswa ngokuqonda isimo sonke sokuthuthukiswa kwephrojekthi kanye nezinto zokusebenza eziyinhloko kanye nabantu zeyunithi yokwakha. Ngokuhlela uhlelo lwezinto zokusebenza kanye nabasebenzi, ukwabiwa okuphelele kwenziwa. Ngaphansi kwesimo sokuqinisekisa inqubekela phambili yokwakha, inqubo ehambisanayo izohlelwa futhi ihlelwe ukuze kusindiswe abasebenzi bokwakha futhi kulwelwe isikhathi sokwakha, ukuze kuthuthukiswe ukusebenza kahle kwemishini emikhulu efana ne-crane.
Njengephuzu elibalulekile lokulungiselela uhlelo lokwakha, uhlelo lobuchwepheshe luhlanganisa kakhulu: uhlelo lokuphakamisa olunembile kanye nokusetshenziswa kwenqubo yokushisela. Lapho kushiselwa izinto ezikhethekile kanye nokuphakamisa amapayipi amakhulu, incazelo yobuchwepheshe yohlelo lokwakha kumele ithuthukiswe, futhi isisekelo esithile sesiqondiso kufanele sithathwe njengesisekelo sokwakhiwa nokufakwa kwendawo. Okwesibili, ngokwezinga lokuqukethwe kohlelo lokwakha kanye nezinyathelo zokuqinisekisa ukuphepha, uhlelo lokwakha lunganqunywa ngokuhlanganisa zonke izici zezici, futhi indawo kufanele iqondiswe ngokufanele nangokuhlelekile ekwakheni okuhambisanayo.
2. Ukusetshenziswa kobuchwepheshe bokwakhiwa kwamapayipi ekwakhiweni
Njengenqubo evamile eShayina, inqubo yokwakhiwa kwamapayipi kufanele inakwe ngenxa yokujula okungaphelele kokwakhiwa kanye nenani eliphansi lokwakhiwa. Isibonelo, amanye amaphrojekthi okwakha aphakamisa ukuthi ukwakhiwa kwamapayipi kumele kube ngaphezu kuka-40%, okuthuthukisa kakhulu ubunzima bamabhizinisi okwakha ngokwesimo sangempela. Njengesixhumanisi esiyinhloko sokufakwa kwamapayipi enqubo, ukujula kokwakhiwa kusesenqubo elula yokwakhiwa kwamabhizinisi amaningi eShayina. Isibonelo, inqubo yokwakhiwa kwangaphambi kwesigaba samapayipi aqondile anokuxhumeka kwendololwane nepayipi ezimbili kanye nenye ingaxazulula inkinga elula yokufaka yamapayipi enqubo. Lapho kufakwa imishini yamapayipi, ayikwazi ukudlala indima yokwakhiwa kwamapayipi. Ngakho-ke, ekwakhiweni kwangempela, kumele sicabangele inqubo yokwakha kusengaphambili, futhi sifake igobolondo elifanele elilungisiwe endaweni yokufaka i-mercury kanye ne-heat exchanger ngaphansi kwezimo. Epayipini elilinganisiwe lokuhlanganisa insimu, lapho ukuhlanganiswa kwensimu sekuqediwe, amalunga okushisela eqembu lensimu elilinganisiwe adonswa emuva esitshalweni esifanelana nokwakhiwa kwangaphambili, futhi imishini ezenzakalelayo isetshenziswa ngqo ekushiseleni, futhi i-flange ehambisanayo ixhunywe ngamabhawodi. Ngakho-ke, umsebenzi wokushisela ngesandla endaweni yokwakha ungalondolozwa futhi ukusebenza kahle kokufakwa kwepayipi kungathuthukiswa.
