Isifinyezo semigomo yolwazi lwamapayipi ensimbi engenamthungo

① isimo sokulethwa

Ibhekisela esimweni sokugcina sepulasitiki noma ukwelashwa kokushisa kokugcina komkhiqizo olethiwe.Ngokujwayelekile, ukugoqa okushisayo noma ukudonsa okubandayo (okugoqa) noma isimo sokukhiqiza: isimo sokwelashwa kokushisa ukuze kuthunyelwe ngemva kokwelashwa okushisa, noma umlilo ovamile (ovamile), ukulungiswa kwekhwalithi, isisombululo esiqinile, isimo se-annealing ngokusho kwesigaba sokwelashwa kokushisa.Lapho uyala, isimo sokulethwa sizoboniswa kwinkontileka.

② ilethwa ngesisindo sangempela noma ngesisindo sethiyori

Isisindo sangempela-Lapho ukulethwa, isisindo somkhiqizo sihanjiswa ngesisindo (isisindo) isisindo;

Isisindo sethiyori-Isisindo somkhiqizo yisisindo esibalwa kusukela kusayizi wensimbi.Ifomula yokubala ilandelayo (edingekayo ngokuya ngesisindo sethiyori, izokhonjiswa kunkontileka): isisindo sethiyori imitha (ukuminyana kwensimbi). ingu-7.85 kg/dms3) ifomula yokubala:

Uhlobo w= (DS) S: isisindo sethiyori se-T eyodwa yepayipi yensimbi imitha, kg/m;Idayamitha yangaphandle ye-D-steel, m: s ukujiya kodonga lwepayipi elilodwa lensimbi, m.

③ izimo zokuqinisekisa

Ngokwendinganiso yamanje yosuku olushiwo lokuhlola nokuqinisekisa ukuthotshelwa kwezinga, okubizwa ngokuthi izimo zesiqinisekiso.Izimo zesiqinisekiso nazo zihlukaniswe:

A. Izimo zesiqinisekiso eziyisisekelo (ezaziwa nangokuthi izimo zesiqinisekiso esiyimpoqo).Kungakhathaliseki ukuthi kubonisiwe noma cha kunkontileka.Zonke izindinganiso zobuchwepheshe zizophunyuka ekuhlolweni, futhi ziqinisekise ukuthi imiphumela yokuhlolwa ihlangabezana nezinhlinzeko ezijwayelekile.Njengokwakheka kwamakhemikhali, okomshini. izakhiwo, ukuchezuka kosayizi, ikhwalithi yendawo kanye nokutholwa kwamaphutha, ukuhlolwa kwe-hydraulic noma i-pressure fan noma ukunwetshwa kwe-1 1 nokunye ukuhlola ukusebenza kwenqubo, yizimo ezidingekayo.

B. Imibandela yesiqiniseko sesivumelwano: Ngaphandle kwemibandela yesiqinisekiso esiyisisekelo esisezingeni, kukhona ” izingxoxo phakathi kwezinhlangothi zombili ngokwezidingo zomfakisicelo. Futhi uyiphawule esivumelwaneni?I-quot;noma ” lapho umthengi eyifuna.Ukufuna…, kufanele kukhonjiswe kwinkontileka “;amanye amakhasimende, izimfuneko zewaranti eziyisisekelo ezifana nokwakheka, izakhiwo zemishini, ukuchezuka kosayizi, njll.) noma izinto zokuhlola ezengeziwe (ezifana nobude bepayipi lensimbi, ukushuba kodonga olungalingani). Le migomo nezimfuneko ezingenhla, lapho u-oda, izinhlangothi ezihlinzekayo nezifunayo izoxoxisana, isayine isivumelwano sobuchwepheshe bokuhlinzeka futhi isikhombise kwinkontileka.Ngakho-ke, le mibandela yaziwa nangokuthi izimo zesiqinisekiso sesivumelwano.Emikhiqizweni enemibandela yesiqinisekiso sesivumelwano, intengo kufanele inyuswe.

④ bhala imiyalelo noma amazwana kuwo

“Iqoqo” elisezingeni lisho iyunithi yokuhlola, okuyiqoqo lokuhlola.Uma iqoqo leyunithi yokulethwa, elibizwa ngokuthi iqoqo lokudiliva.Lapho iqoqo lokulethwa likhulu, iqoqo ngalinye lokulethwa lingahlanganisa amaqoqo amaningana okuhlola: lapho iqoqo lokulethwa. incane, iqoqo lokuhlola lingahlukaniswa libe amaqoqo amaningana okulethwa.Ukwakheka "kwenqwaba" kuvame ukuba nalokhu okulandelayo (bona izindinganiso ezifanele):

I. Iqoqo ngalinye lizokwakhiwa ngamapayipi ensimbi anenombolo yomkhiqizo ofanayo (izinga lensimbi), inombolo yesithando somlilo efanayo (ithangi) noma inombolo efanayo yesithando somlilo sikanina, ukucaciswa okufanayo kanye nesistimu yokushisa efanayo (izikhathi zesithando somlilo).

B. Kumapayipi esakhiwo sensimbi yensimbi yekhwalithi ephezulu namapayipi oketshezi, iziko (amathangi) ahlukene angaba nenombolo yomkhiqizo ofanayo, ukucaciswa okufanayo kanye nesistimu efanayo yokushisa ukushisa (izikhathi zesithando somlilo).Ukwakhiwa kwepayipi lensimbi.

C. Iqoqo ngalinye lepayipi lensimbi elishiselwe kufanele libe nepayipi lensimbi elinezinga elifanayo (izinga lensimbi) kanye nokucaciswa okufanayo.

⑤ insimbi yekhwalithi nekhwalithi ephezulu

Ngamazinga e-GB / T699-1999 kanye ne-GB / T3077-1999, umkhiqizo wayo ubuye ngo-“A”, ngensimbi yezinga eliphezulu, ngaphandle kwalokho insimbi yekhwalithi ephezulu.Insimbi yekhwalithi ethuthukisiwe iphakeme kokunye noma kukho konke okulandelayo:

A. Yehlisa ububanzi bengxenye yokuqukethwe:

B. Yehlisa okuqukethwe kwezinto eziyingozi (njengokugeleza, i-phosphorus nensimbi):
