Inombolo yemodeli isho ukuthi: "PH" ikhombisa indandatho yesandiso, futhi "21" ikhombisa umthwalo ophukayo ongu-210kN.
Izici Zomkhiqizo: Yenziwe kusetshenziswa-inqubo yokubumba ucezu olulodwa, indandatho iqine kakhulu. Indawo eshisayo-efakwe amagalani inikeza ukumelana nokugqwala okuhle kakhulu futhi imelana nezindawo zokusebenza zangaphandle ezinokhahlo. Isakhiwo sayo esilula, esinezixhumi zohlobo lwendandatho{4}}emikhawulweni yomibili, isiza ukuxhuma nokulungiswa kobude phakathi kokufakwayo okuhlukene, okwenza kube lula ukukusebenzisa.
Ubukhulu obuyinhloko: ububanzi obungu-30mm, ububanzi bembobo obungu-24mm, ubude bendandatho engu-160mm, ubude obungu-210mm obuphelele, kanye nesisindo esingaba ngu-1.6kg.
Amapharamitha Obuchwepheshe: Umthwalo ophulayo ongu-210kN.
Uhlelo lokusebenza: Isetshenziselwa ukuxhuma izintambo zesivikelo ekufakweni, phakathi kwama-clamp nezintambo zesivikelo, naphakathi kwamakhondaktha ombani nemibhoshongo yezigxobo. Kuwuxhumano lwendawo yonke.
Inombolo yemodeli evamile ye-PH-21 iringi yesandiso ithi "PH-21130." Igama elithi "130" likhombisa ubude obungu-130mm kanye nomthwalo ophukayo ongu-210kN. Yakhiwe ngensimbi eyindilinga, ivame ukubizwa ngokuthi yindandatho ehambisanayo ngenxa yesakhiwo sayo esihambisanayo. Ngokuyinhloko isetshenziselwa ukunweba noma ukushintsha isiqondiso soxhumano. Amandla ayo aqinile ngesikhathi sokusetshenziswa ahlobene nomthwalo ophukayo kanye nensimbi ye-alloy, ikakhulukazi inqubo yokubumba. Ngokuvamile, amandla okubamba makhulu noma alingana no-400MPa. Ezindaweni ezikhethekile, ama-alloy anezinga lokushisa eliphansi angasetshenziswa ukukhulisa amandla okubamba ukuya ku-Greater than noma alingana no-500MPa. Kodwa-ke, kufanele kuthathwe izinyathelo zokuqapha ukugwema ukuphuka okubandayo ngesikhathi sokusetshenziswa.
Ubani onentshisekelo enkulu endandeni yesandiso ye-PH-21? Khona-ke, sidinga ukucabangela izinhlelo zokusebenza eziyinhloko zendandatho yokunweba:
Amayunithi wokwakha ubunjiniyela bamandla
Imigqa-emide ebanzi engaphezulu, izintambo zokudonsa kombhoshongo osekhoneni, nezinye izindawo zokuxhuma zikalayini okwazi ukumelana nomthwalo wokuphuka ongu-200kN;
Amaqembu okusebenza nokugcinwa kwegridi
Ukushintsha{0}}izixhumi zamandla aphansi ngesikhathi sokunwetshwa kwamandla kanye nokulungiswa kwemigqa emidala, ukulungisa ngokushesha ukuwohloka kweringi okubangelwa ukudlidliza komoya noma ukulayishwa kweqhwa, nokuhambisana nezinhlaka ezijwayelekile zezintambo zehadiwe;
Ukwakhiwa kwemvelo okukhethekile
Ukuze usetshenziswe ezindaweni ezibolayo, khetha insimbi eshisayo-ecwilisa ingxubevange ene-zinc coating engu-Greater noma elingana no-70μm ukuze welule impilo yesevisi.
Uma ufaka futhi ufaka isandiso se-PH-21, naka amaphuzu alandelayo:
Ngaphezu-nolawulo lwenkomba
Indandatho yesandiso ingadambisa-ukushuba, kodwa amandla eyunithi yezingxenyekazi zekhompiyutha kufanele aqashwe kanyekanye ukuze kuvinjelwe-imikhawulo;
Ukunemba kokulungiswa kobude beyunithi yezinhlamvu
Lapho kunxeshezelwa umehluko wobude bombhoshongo noma ukuchezuka kwentambo yesivikelo, ubude beyunithi yezinhlamvu kufanele bulinganiswe ngokunembile kusetshenziswa ipuleti lokulungisa ukuze kugwenywe{0}}ukungalingani kwephuzu elilodwa;
Ukuqinisekisa ibanga lokuphepha ngogesi
Uma isetshenziselwa ukugxuma emibhoshongweni etshekile, qinisekisa imvume encane phakathi kwe-conductor kanye ne-crossarm ngemuva kokufakwa kwendandatho yokunweba ukuvimbela ukuphuma kukagesi.
PH-21 iringi yesandiso ayidingi nje kuphela ukufakwa nokwakhiwa ngokucophelela, kodwa futhi nokunakekelwa nokunakekelwa kwesikhathi eside. Uma kwenzeka ukuqhekeka noma izinguquko zokusebenza, zishintshe ngokushesha.
Futhi, ngaphambi kokusebenzisa PH-21 iringi yesandiso, qinisekisa ukuthi iringi ihlanzekile futhi ayilimele. Sebenzisa-ibhulashi elithambile{3}elinamabristled kanye nokokugeza okuphakathi nendawo ukuze ukhuhle kahle ingaphezulu lendandatho ukuze ususe kahle uwoyela, uthuli, nezinsalela, futhi ugweme ukulimala{5}}kokubamba ukugqwala okubangelwa izinto ezilimazayo. Ngemva kokugeza ngamanzi, sula wome ngendwangu{7}}yamahhala noma wome umoya ukuze uvimbele amabala amanzi ayinsalela angase abangele ukugqwala. Gwema ukusebenzisa amanzi ashisayo noma izincibilikisi ezinotshwala, njengoba zingathinta ubuqotho bezinto ezibonakalayo. Indandatho yesandiso ye-PH-21 ehlanzekile ingakhuphula ukusebenza komkhiqizo futhi ibeke isifaki esimweni esihle.
Amashadi ashisayo: indandatho ye-ph-21, i-China ph-21 abakhiqizi bendandatho yokwengeza, abahlinzeki, imboni
