Ungawabona kanjani amapayipi ensimbi angamanga naphansi:
1. Amapayipi ensimbi angamanga nangaphansi anezindonga eziwugqinsi ajwayele ukugoqwa. Ukugoqa kukhona imigqa egoqiwe ehlukahlukene eyakhiwe phezu kwamapayipi ensimbi anezindonga eziwugqinsi. Lesi sici sivame ukugijima kulo lonke isiqondiso se-longitudinal yomkhiqizo. Isizathu sokugoqa ukuthi abakhiqizi abangenangqondo baphishekela ukusebenza kahle futhi ukunciphisa kukhulu kakhulu, okuholela ezindlebeni. Ukugoqa kuzokwenzeka phakathi nenqubo elandelayo yokugoqa. Umkhiqizo ogoqiwe uzoqhekeka ngemuva kokugoba, futhi amandla ensimbi azoncishiswa kakhulu.
2. Amapayipi ensimbi angamanga nangaphansi anezindonga eziwugqinsi ngokuvamile anezindawo ezinemigodi ngaphezulu. I-Pockmarking iphutha elingalingani endaweni yensimbi ebangelwa ukuguga okunzima kwe-groove rolling. Njengoba abakhiqizi bamapayipi ensimbi aqinile anezindonga eziwugqinsi bephishekela inzuzo, ukugingqika kwemigodi kuvame ukweqa izinga.
3. Amapayipi ensimbi mbumbulu anezindonga eziwugqinsi ajwayele ukuba nezibazi. Kunezizathu ezimbili: (1). Impahla yamapayipi ensimbi angamanga futhi aphansi ayilingani futhi iqukethe ukungcola okuningi. (2). Imishini yokuqondisa yabakhiqizi bezinto zomgunyathi nabaphansi ilula futhi kulula ukunamathela ensimbi. Lokhu kungcola kungabangela kalula izibazi ngemva kokuluma ama-roller.
4. Ingaphezulu lamapayipi ensimbi mbumbulu nangaphansi anezindonga eziwugqinsi ajwayele ukuqhekeka ngenxa yokuthi impahla yawo eluhlaza iyi-adobe, enezimbotshana eziningi. I-adobe ingaphansi kokucindezeleka okushisayo phakathi nenqubo yokupholisa, okubangela ukuqhekeka, kanye nemifantu ivela ngemva kokugingqika.
5. Amapayipi ensimbi angamanga naphansi anezindonga eziwugqinsi kulula ukuwanwaya. Isizathu siwukuthi izinto zokusebenza zabakhiqizi bamapayipi ensimbi angu-fake futhi aphansi aqinile alula futhi kulula ukukhiqiza ama-burrs nokunwaya ubuso bensimbi. Imihuzuko ejulile inciphisa amandla ensimbi.
6. Amapayipi ensimbi angamanga nangaphansi anezindonga eziwugqinsi awacwebezeli futhi abomvu ngokukhanyayo noma ngombala afana nensimbi yengulube. Kunezizathu ezimbili. Enye ukuthi ayinalutho i-adobe. Okwesibili ukuthi izinga lokushisa eliguquguqukayo lemikhiqizo yensimbi engelona iqiniso neliphansi alilona izinga. Izinga lokushisa labo lensimbi likalwa ngokuhlola okubukwayo. Ngale ndlela, ukugoqa akukwazi ukwenziwa ngokuya ngendawo ecacisiwe ye-austenite, futhi ukusebenza kwensimbi ngokwemvelo ngeke kuhlangabezane nezindinganiso.
7. Izimbambo eziphambanayo zamapayipi ensimbi mbumbulu nangaphansi anezindonga eziwugqinsi zincane futhi ziphansi, futhi ngokuvamile zibonakala zingagcwali kakhulu. Isizathu siwukuthi ukufeza ukubekezelelana okukhulu okungalungile, inani lokunciphisa lokudlula kokuqala komkhiqizo oqediwe likhulu kakhulu, isimo sensimbi sincane kakhulu, futhi iphethini yembobo ayigcwaliswa.
8. Ingxenye ephambanayo yepayipi lensimbi engugqinsi enodonga mbumbulu i-oval. Isizathu siwukuthi ukuze ulondoloze izinto zokwakha, umenzi usebenzisa inani elikhulu lokunciphisa kumaphasi amabili okuqala we-roller eqediwe. Amandla alolu hlobo lwe-rebar ancipha kakhulu, futhi awahlangabezani nobukhulu obuphelele be-rebar. izindinganiso.
9. Ukubunjwa kwensimbi kufana nomfaniswano, i-tonnage yomshini we-shear ebandayo iphezulu, futhi ubuso bokuphela kwekhanda lokusika bushelelezi futhi buhlanzekile. Kodwa-ke, ngenxa yekhwalithi ephansi yezinto ezibonakalayo, ubuso bokugcina bekhanda lokusika lezinto ezingezona ezingezona eziphansi nezingaphansi ngokuvamile buba nokwenzeka kokulahlekelwa inyama, okungukuthi, akulingani futhi akunalucwebe lwensimbi. Futhi ngenxa yokuthi imikhiqizo ekhiqizwa abakhiqizi bezinto zomgunyathi nabaphansi inamakhanda ambalwa, izindlebe ezinkulu zizovela ekhanda nasemsila.
10. Izinto ezisetshenziswa amapayipi ensimbi aqinile anezindonga eziwumgunyathi ziqukethe ukungcola okuningi, ukuminyana kwensimbi kuncane, futhi ubukhulu abunakubekezelelwa, ngakho-ke kungakalwa futhi kuhlolwe ngaphandle kwe-vernier caliper. Isibonelo, ku-rebar 20, indinganiso ibeka ukuthi ukubekezelelana okungalungile okuphezulu ngu-5%. Lapho ubude obunqunyiwe buyi-9M, isisindo sethiyori senduku eyodwa singu-120 kg. Isisindo sayo esincane kufanele sibe: 120X (l-5%) = 114 kg, enesisindo Uma isisindo sangempela sesiqephu esisodwa singaphansi kwamakhilogremu angu-114, iyinsimbi yomgunyathi ngoba ukubekezelelana kwayo okungalungile kudlula u-5%. Ngokuvamile, umphumela wokukala okuhlanganisiwe kwesigaba uzoba muhle, ikakhulukazi kucatshangelwa izindaba zephutha elikhulayo kanye nethiyori yamathuba.
11. Ububanzi bangaphakathi bamapayipi ensimbi mbumbulu nangaphansi anezindonga eziwugqinsi bushintshashintsha kakhulu ngenxa yalokhu: 1. Izinga lokushisa lensimbi elingazinzile linohlangothi lwe-yin ne-yang. ②. Ukwakheka kwensimbi akulingani. ③. Ngenxa yemishini engahluziwe namandla esisekelo aphansi, umshini wokugaywa une-bounce enkulu. Kuzoba nezinguquko ezinkulu kububanzi bangaphakathi phakathi nesonto elifanayo. Ukucindezeleka okunjalo okungalingani emigoqweni yensimbi kuzoholela kalula ekuqhekekeni.
12. Izimpawu zokuhweba nokuphrinta kwamapayipi ensimbi anezindonga eziwugqinsi zilinganiselwe.
13. Ngezintambo ezinkulu ezinobubanzi obungu-16 noma ngaphezulu kumapayipi ensimbi amathathu, ibanga phakathi kwezimpawu zokuhweba ezimbili lingaphezu kwe-IM.
14. Imigoqo yobude ye-rebar yensimbi engenasici ivamise ukuba namagagasi.
15. Abakhiqizi bamapayipi ensimbi angamanga futhi angaphansi aqinile awasebenzi, ngakho ukupakishwa kukhululekile. Izinhlangothi ziyi-oval.

Ukugeleza kwenqubo yepayipi elishiselwe: ukuqaqa - ukwenza isicaba - ukugunda ekugcineni nokushisela - i-looper - ukwakha - ukushisela - ukususwa kwe-weld yobuhlalu bangaphandle - ukulungiswa kwangaphambili - ukwelashwa kokushisa okufakwayo - ukulinganisa nokuqondisa - Ukuhlolwa kwe-eddi yamanje - ukusika - ukuhlolwa kwe-hydraulic - pickling - ukuhlolwa kokugcina - ukupakisha
