Umlando we-rebar coupler

Embonini yezokwakha, izindlela zokuxhuma zokuqinisa zendabuko ezifana nama-lap joints kanye nokuxhumeka kwe-welding azikwazi ukwanelisa ukuthuthukiswa okusheshayo kwemboni yezokwakha mayelana nekhwalithi yokuxhuma, ukusebenza kahle, nokusebenza. Ukubuyekezwa okuqhubekayo kobuchwepheshe be-conical thread coupler technology kuye kwaholela ekuthuthukisweni okusha kuyo yonke imboni kanye nokuthuthuka okuqhubekayo kwezobuchwepheshe. Ngakho-ke, ibha yensimbiubuchwepheshe bokuxhumanaiphumelele ngendlela ethile, futhi inezici zayo ukuze ikwazi ukujwayela imboni ehlala ithuthuka kanye nemikhuba yezenhlalo. Indlela yokuxhumana ye-lap ayikwazi ukusetshenziselwa ukuxhuma izinsimbi zensimbi ezinosayizi omkhulu, futhi ukushisela kunezingqinamba eziningi (njengezinto zensimbi ezingaqinile, ukushisela okuncane, njll.; ukunikezwa kwamandla okungazinzile noma izinga eliphansi le-welder; ubude besikhathi esiqinile, umthamo onganele; imiphumela yesimo sezulu kanye nesimo sezulu esinjengomoya nemvula; amapulani okwakhiwa kwezindawo ezinezidingo eziphakeme zokuvikela umlilo; ikhwalithi nesivinini sokuxhuma i-rebar evundlile).

Ikhwalithi yokushisela ayikwazi ukuqinisekiswa. Uxhumano lwemishini lwezinsimbi zensimbi lungagwema ubunzima obungenhla futhi lubonise izinzuzo ezisobala. Ngasekupheleni kweminyaka yawo-1980, ngokwethulwa kobuchwepheshe bokuxhumana bemishini obuthuthukile bakwamanye amazwe, kuhambisana nemizamo eqhubekayo yochwepheshe abafanelekile bezinye izikhungo zocwaningo lwesayensi eShayina, ubuchwepheshe bokuxhumana bemishini obuqinisiwe baseShayina buthuthuke ngokushesha. Uxhumano lwemishini seludlule ezigabeni ezihlukene zokuthuthuka ezifana ne-sleeve cold extrusion, i-taper threading, ukuphazamisa intambo eqondile kuze kufike entanjeni eqondile egoqekayo, futhi ubuchwepheshe sebukhulile futhi buzinzile, futhi izindleko ziye zehliswa ngokuqhubekayo.

Naphezu kwalokhu, ubuchwepheshe bokuxhuma intambo yase-Chinalisenegebe elithile uma liqhathaniswa namazwe angaphandle. Enye yezinkinga ezigqame kakhulu ukuthi inkundla ayishadile. I-rebar esuka ku-diameter ye-16 kuya ku-40 mm ine-pitch engu-2.5 mm, futhi i-pitch engu-2.5 mm ifaneleka kangcono ububanzi obungu-22 mm. Ukuqinisa uxhumano. Nakuba zisekhona izikhala kwezinye izindawo, lezi zikhala zizoncipha njengoba ubuchwepheshe bokukhiqiza imikhono yensimbi yaseChina buqhubeka nokuvuthwa.

I-Conical thread coupler eqiniswe yi-Yida inemibandela elandelayo:

1. Akukho mfantu ebusweni be-i-conical thread couplerfuthi izintambo zigcwele futhi azikho ezinye izici.

 2. Ukuhlolwa kwephrofayili yezinyo elifanelekile, hlola ukunemba kwe-dimensional nge-gauge ye-thread plug gauge.

 3. Ingaphandle lezintambo ezihlanganisa intambo yamamodeli nosayizi abahlukahlukene kufanele zibe namazinga asobala we-rebar namadayamitha.

 4. Izimbobo emaphethelweni womabili we-conical thread coupler kufanele zivalwe ngesembozo sepulasitiki ukugcina ingaphakathi lihlanzekile futhi lihlanzekile.

Umkhono wensimbi oqinisiwe we-Yida/intambo ye-rebar eqondile inezinzuzo ezilandelayo:

 1. Akuthintwa izinto eziningi ezifana nokwakheka kwamakhemikhali ensimbi, izici zomuntu, isimo sezulu, ugesi, njll.;

 2. Ayinakho ukungcola, ihlangabezana nezidingo zokuvikelwa kwemvelo, futhi iphephile futhi inokwethenjelwa ngaphandle kokusebenza komlilo ovulekile;

 3. Uhlu olubanzi lwezinhlelo zokusebenza, ezisebenza ezinhlobonhlobo zokuma kanye nokuxhumana okufanayo, okuhlukile kokuqinisa ububanzi;

 4. Amandla aphezulu, izinga elizinzile nelithembekile;

 5. Ukusebenza okulula, isivinini sokwakha.

Eminyakeni yamuva nje, iChina yenze inqubekelaphambili enkulu kubuchwepheshe bokuxhumana bokuqinisa imishini yensimbi. Ama-conical thread couplers aqiniswe ngensimbi asetshenziswa kabanzi kumaphrojekthi amakhulu afana nezakhiwo eziphakeme kakhulu, amabhuloho, izitimela ezihamba ngesivinini esikhulu, izimboni zamandla enuzi, nezakhiwo zensimbi. Imikhono yokuxhuma i-Rebar kulula ukuyisebenzisa, ayinalangabi elivulekile, iphephile futhi iyashesha, futhi yonga kakhulu izinsiza zempahla namandla abasebenzi. Zihlonishwa kakhulu e-China nakwamanye amazwe, futhi kancane kancane zithatha indawo yobuchwepheshe bendabuko bokubopha kanye nokushisela.

I-HeBei YiDa eqinisa umkhono wokuxhuma insimbi isetshenziswa kabanzi kumaphrojekthi amakhulu njengebhuloho le-hong Kong-zhuhai-macao, isikhungo samandla enuzi e-fuqing, ujantshi wesitimela we-beijing-shanghai wesivinini esikhulu kanye nesikhungo sase-Wuhan saseGreenland.
