Ibhawodi yangaphandle ene-hexagonal iyinsizakalo yensimbi, eyaziwa nangokuthi isikulufu esine-hexagonal yangaphandle, isikulufu esine-hexagonal yangaphandle, noma ibhawudi yangaphandle ene-hexagonal.

9. Amabhawodi anamandla aphezulu ngokuvamile enziwa ngensimbi yokuqina okuphezulu (insimbi engu-45 (8.8s), 20MmTiB (10.9s), okungamabhawodi acindezelwe ngaphambili. Amabhawodi ohlobo lwe-Friction acindezelwa ngaphambili ngesikrufu se-torque, futhi amabhawodi ohlobo lwe-pressure ahlulwe nge-plum blossom head. kuqiniswe.

10. Amabhawodi ajwayelekile ngokuvamile eba grade 4.4, 4.8, 5.6, kanye no-8.8. Amabhawodi anamandla aphezulu ngokuvamile ahlukaniswa njengebanga lesi-8.8 kanye nebanga le-10.9, kanti ibanga elingu-10.9 yilona elivame kakhulu.

11. Izimbobo ezikulufi zamabhawudi ajwayelekile zingahle zingabi zinkulu kunalezo zamabhawudi anamandla. Eqinisweni, izimbobo zamabhawodi ezivamile zincane uma kuqhathaniswa.

12. Izimbobo zezikulufi zebhawodi ezijwayelekile A nezinga B ngokuvamile zinkulu ngo-0.3-0.5mm kuphela kunebhawodi. Izimbobo zezikulufu ze-C-grade ngokuvamile zinkulu ngo-1.0-1.5mm kunamabhawodi.

13. Amabhawodi anamandla amakhulu ohlobo lwefriction adlulisa imithwalo ngokungqubuzana, ukuze umehluko phakathi kwesikulufu nembobo yesikulufu ungafinyelela ku-1.5-2.0mm.

Izici ezijwayelekile zokudlulisa amandla okucindezela okuthwala amabhawodi angamahexagon angaphandle anokuqina okuphezulu ukuqinisekisa ukuthi ngaphansi kokusetshenziswa okuvamile, amandla okugunda aweqi amandla okungqubuzana, afana nalawo ohlobo lokungqubuzana kwamabholidi anamandla amakhulu. Lapho umthwalo ukhula ngokuqhubekayo, ukushelela okuhlobene kuzokwenzeka phakathi kwamapuleti axhumayo. Ukuxhumana kuncike ekuphikiseni kwe-shear kwesikulufu kanye nokucindezela odongeni lwembobo ukuze kudluliselwe amandla, afana namabhawodi ajwayelekile. Ngakho-ke, umehluko phakathi kwesikulufu kanye nembobo yesikulufu mncane kancane, kusukela ku-1.0 kuya ku-1.5mm.

Ibhawodi yehange lesisekelo sekholomu

19. Amabhawodi okusetshenzwa kulengwa awanabanga, izinto zokwakha kuphela: Q235 kanye ne-Q345. Amabhawodi okusetshenzwa kulengwa avame ukusetshenziswa kakhulu ezakhiweni zomakhiwo amabhawodi onyawo lwekholomu.

20. Amabhawodi onyawo lwekholomu awawona amabhawodi ajwayelekile noma aphansi kunamabhawudo anamandla aphezulu. Ukukhuluma ngokuqinile, akukona okwamabhawudi. Ibhawodi ye-ancho eyisisekelo yekholomu ngokuvamile i-M20 noma i-M24.

Amazinga okukhiqiza amabhawodi okukhonkwa ezinyawo zekholomu kufanele afane nalawo amabhawodi ajwayelekile. Ubude bebhawodi lehange elithengelwe isisekelo sekholomu kufanele buhlobane namandla ashayisanayo phakathi kwayo nokhonkolo, kanye nesimo sebhawodi lehange.

Amabhawodi okunweba namabhawodi amakhemikhali

22. Kungakhathaliseki ukuthi amabholothi okunweba okusetshenzelwa kuwo noma amabhawodi ayisikhonkwane amakhemikhali, awawona amafomu okuxhuma ezimisweni ezijwayelekile zikazwelonke, futhi lokho kuxhumana kufanele kugwenywe, ikakhulukazi ekuxhumekeni okubalulekile. Izingxenye ezishumekiwe ngaphambili kufanele zisetshenziswe kubo bonke.

23. Ibhawodi lehange lokunwetshwa lincike ikakhulukazi ekuvulekeni kwekhabhinethi yepayipi lokunweba kanye namandla ashayisanayo akhiqizwa ukhonkolo ukuze amelane nokudonsa. Ubukhulu bamandla okuqina buhlobene eduze nenqubo yokwakha, futhi kunezici ezibalulekile zobuntu ezihilelekile. Ngakho-ke, ukwenza izivivinyo eziqinile ngokuhlola okungahleliwe nakho akusizi ngalutho.

24. Amabhawodi amakhemikhali ehange akhiwa ngokubhoboza izimbobo ngomshini wokubhoboza, ukufaka induku yebhawodi, bese ejova udaka lwamakhemikhali ukuze kuzuzwe umphumela wokubambelela. Imikhiqizo evamile efana ne-Huiyu ne-Heineken.

Amabhawodi okunweba namabhawodi amakhemikhali ayingxenye yezakhiwo zebhawodi lehange. Kwezinye izimo, amabhawodi okunweba noma ama-anchor bolt amakhemikhali ayadingeka ngoba awashumekiwe ngaphambili. Kodwa lesi simo kufanele sigwenywe kumklamo. Ngoba ama-anchor bolt kufanele ashumekwe ngaphambili. Isibonelo, amabhawodi ehange onyawo lwekholomu. Ngoba ngale ndlela kuphela lapho singakwazi ukuqinisekisa ukunamathela okuhle nokucindezeleka. Ngaphezu kwalokho, ukubhoboza izimbobo ngemva kwalokho kuvame ukuthinta izinsimbi zensimbi ezigxilile kanye nokhonkolo kukhonkolo
