Isingeniso
Uma kukhulunywa ngokwakha izakhiwo ze-pier zesikhulumi sasolwandle, ukukhetha izinto ezifanele kubalulekile. Enye yezinto ezinjalo eziye zathandwa kakhulu amashubhu asikwele, ikakhulukazi lawo enziwe nge-ASTM A-572 Grade 50. Kulesi sihloko, sizohlola izinzuzo zokusebenzisa amashubhu asikwele ezakhiweni ze-pier zesikhulumi sasolwandle, sihlolisise amashubhu ensimbi yemikhumbi kanye namazinga ensimbi yokwakha imikhumbi, sixoxe ngezinto zokwakha imikhumbi, sikhanyise amapayipi emikhumbi kanye nokufakwa kwamapayipi emikhumbi, futhi sinikeze ukuqonda okuphelele kokuthi amashubhu asikwele adlala indima ebalulekile kanjani ekwakheni imikhumbi.
Ayini amashubhu asikwele?
Amashubhu ayisikwele ayizingxenye zesakhiwo ezingenalutho (i-HSS) ezibonakala ngesimo sazo esingunxande. Zenziwe ngezinto ezahlukene, okuhlanganisa nensimbi, futhi zisetshenziswa kabanzi ekwakheni ngenxa yokuguquguquka kwazo namandla azo.
Izinto: ASTM A-572 IGAMA 50
Enye yezinto ezifanele kakhulu izakhiwo ze-pier yesikhulumi sasolwandle yi-ASTM A-572 Grade 50. Le nto yaziwa ngamandla ayo angavamile, okwenza ifaneleke kakhulu ekusetshenzisweni lapho ukuqina kubaluleke kakhulu. Izakhiwo ze-ASTM A-572 Grade 50, njengokuqina okuphezulu kanye nokumelana okuhle komthelela, kuqinisekisa ukuzinza nokuthembeka okudingekayo ezindaweni zasolwandle.
Izinzuzo zokusebenzisa amashubhu asikwele ezakhiweni zeplatifomu yasolwandle
Ukusebenzisa amashubhu asikwele ezakhiweni zeplatifomu yesikhulumi sasolwandle kunikeza izinzuzo eziningana. Okokuqala, ubuqotho besakhiwo kanye namandla anikezwa amashubhu asikwele kuwenza abe ukukhetha okuthembekile kokubekezelela izimo ezinzima zasolwandle. Ngaphezu kwalokho, amashubhu asikwele amelana kakhulu nokugqwala, okuqinisekisa ukuthi ahlala isikhathi eside futhi anciphisa izindleko zokulungisa. Ngaphezu kwalokho, amashubhu asikwele anikeza izinketho zokuguquguquka kanye nokwenza ngokwezifiso, okuvumela abaklami ukuthi bawavumelanise nezidingo ezahlukene zesakhiwo.
Ishubhu yensimbi yokuthutha kanye namazinga ensimbi yokwakha imikhumbi
Ekwakhiweni kwemikhumbi, ukukhethwa kwezinto ezifanele kubalulekile ukuqinisekisa ukuphepha nokusebenza kahle kwemikhumbi yasolwandle. Amapayipi ensimbi yemikhumbi ayisici esibalulekile ekwakhiweni kwemikhumbi, njengoba ekhonza izinjongo ezahlukene njengokuthutha uketshezi kanye nokunikeza ukwesekwa kwesakhiwo. Amazinga ahlukene ensimbi yokwakha imikhumbi asetshenziselwa amapayipi ensimbi yemikhumbi, ngalinye linikeza izakhiwo ezithile kanye namandla afanele ukusetshenziswa okuhlukahlukene.
Izinto zokwakha imikhumbi yezakhiwo zasolwandle
Ngaphandle kwamapayipi ensimbi yemikhumbi, ukwakhiwa kwemikhumbi kudinga izinto eziningi zokwakha izakhiwo zasolwandle ezithembekile nezihlala isikhathi eside. Lezi zinto zifaka izinsimbi ezinamandla aphezulu, ama-alloy e-aluminium, izinhlanganisela, kanye nokwembozwa okuthuthukisiwe. Izinto ngazinye zinezakhiwo ezithile ezifaka isandla ekusebenzeni okuphelele kwesakhiwo sasolwandle.
Amapayipi okuthutha kanye nokufakwa kwamapayipi okuthutha
Amapayipi emikhumbi abalulekile ekusebenzeni kahle nasekusebenzeni kahle kwemikhumbi yasolwandle. Adlala indima ezinhlelweni ezifana nokuhlinzekwa kukaphethiloli, ukujikeleziswa kwamanzi, kanye nokuphathwa kwemfucuza. Ukufakwa kwamapayipi emikhumbi kuyizinto ezisetshenziswa ukuxhuma nokulawula ukugeleza koketshezi ngaphakathi kwezinhlelo zamapayipi omkhumbi. Amapayipi emikhumbi akhethwe futhi afakwe kahle kanye nokufakwa kwamapayipi kuqinisekisa ukuphepha nokusebenza kahle kwemisebenzi yasolwandle.
Ukusetshenziswa kwamapayipi esikwele ekwakheni imikhumbi
Amashubhu ayisikwele athola ukusetshenziswa okubanzi ekwakheni imikhumbi ngenxa yezakhiwo zawo eziyingqayizivele. Avame ukusetshenziswa njengezakhi zesakhiwo emathunjini emikhumbi, emadekini, nasezindaweni eziphakeme. Amashubhu ayisikwele angamelana nemithwalo esindayo, anikeze ukwesekwa okudingekayo, futhi anikele ekuzinzeni okuphelele komkhumbi. Ngaphezu kwalokho, amashubhu ayisikwele anikeza ukuguquguquka ekuklanyweni nasekuzivumelaniseni nezidingo ezahlukene zokwakha imikhumbi.
Ukuqina nokumelana nokugqwala kwamashubhu asikwele
Enye yezinzuzo ezibalulekile zokusebenzisa amashubhu asikwele ekwakheni imikhumbi ukuqina kwawo kanye nokumelana nokugqwala. Imvelo yasolwandle ibeka izakhiwo ezimweni ezinzima njengokuvezwa emanzini anosawoti kanye nomswakama. Amashubhu asikwele enziwe ngezinto ezifana ne-ASTM A-572 Grade 50 aklanyelwe ngqo ukumelana nezimo ezinjalo nokugcina ubuqotho besakhiwo sawo ngokuhamba kwesikhathi.
Amandla nobuqotho besakhiwo
Amashubhu ayisikwele anikeza amandla amahle kakhulu kanye nokuqina kwesakhiwo, okwenza abe afanele izakhiwo ze-pier zesikhulumi sasolwandle. Isimo sesikwele sisabalalisa umthwalo ngokulinganayo, kunciphisa ingozi yokwehluleka kwesakhiwo. Izakhiwo ezinamandla aphezulu zamashubhu ayisikwele ziqinisekisa ukuphepha nokuthembeka kwezakhiwo zasolwandle, ngisho nangaphansi kwezimo ezidinga kakhulu.
Izinketho zokuguquguquka kanye nokwenza ngezifiso
Enye inzuzo ephawulekayo yamashubhu asikwele ukuthi ayakwazi ukuguquguquka futhi angakhetha ukwenza ngendlela oyifisayo. Angenziwa kalula, ashiselwe, futhi alolongwe ukuze ahlangabezane nezidingo ezithile zomklamo. Amashubhu asikwele anikeza abaklami nonjiniyela inkululeko yokwakha izakhiwo ezisebenzayo nezijabulisa ngobuhle, okuthuthukisa ukusebenza kahle kanye nokukhanga kwezakhiwo ze-pier zesikhulumi sasolwandle.
Ukusebenza kahle kwezindleko kanye nokusimama
Ukusebenzisa amashubhu asikwele ezakhiweni zeplatifomu yasolwandle kuletha izinzuzo zokusebenzisa izindleko kanye nokusimama. Ukuphila isikhathi eside kanye nezidingo zokunakekelwa okuphansi kwamashubhu asikwele kusiza ekunciphiseni izindleko zomjikelezo wokuphila. Ngaphezu kwalokho, ukusebenzisa izinto ezifana ne-ASTM A-572 Grade 50 kuqinisekisa ukuthi izakhiwo zihlangabezana nezindinganiso eziphakeme kakhulu zokusimama, okwenza kube ukukhetha okunobungani nemvelo.
Isiphetho
Ekuphetheni, amashubhu asikwele, ikakhulukazi lawo enziwe nge-ASTM A-572 Grade 50, anikeza izinzuzo eziningi zezakhiwo ze-pier zesikhulumi sasolwandle. Ukuqina kwawo, ukumelana nokugqwala, amandla, ukuguquguquka, kanye nokusebenza kahle kwezindleko kuwenza abe ukukhetha okuhle kakhulu kwezicelo zokwakha imikhumbi. Ngokufaka amashubhu asikwele ezakhiweni zasolwandle, abaklami nonjiniyela bangakha amapulatifomu aqinile nathembekile amelana nemvelo yasolwandle eyinselele.
Imibuzo Evame Ukubuzwa
Nakuba i-ASTM A-572 Grade 50 iyindlela ethandwayo, kunezinye izinto ezitholakalayo kuye ngezidingo ezithile.
Yebo, amashubhu ayisikwele anezicelo ezimbonini ezahlukahlukene njengokwakha, ezokuthutha kanye nengqalasizinda.
Amashubhu ayisikwele anikeza ukusebenza okuhle kakhulu ezakhiweni zasolwandle, kodwa ukucatshangelwa kokuklama okufanele kanye nokukhetha izinto kubalulekile ukuze kube nemiphumela emihle kakhulu.
Amashubhu ensimbi yemikhumbi aklanyelwe ukuhlangabezana neziqondiso eziqinile kanye nezindinganiso ezithile eziqondene nezicelo zasolwandle, kucatshangelwa izici ezifana nokumelana nokugqwala kanye nokumelana nomthelela.
Ukufakwa kwamapayipi omkhumbi okuvamile kufaka phakathi izindololwane, ama-tee, ama-reducer, ama-valve, kanye nama-coupling asetshenziselwa ukuxhuma nokulawula ukugeleza koketshezi ezinhlelweni zamapayipi omkhumbi.
