The screw ground mulundi mulu wobowola pansi, womwe umadziwika kuti umakhala ndi pobowola ndi chitoliro chobowola, ndipo pobowola kapena chitoliro chobowola chimalumikizidwa ndi cholumikizira chamagetsi; Muluwo utathamangitsidwa mobisa, sudzachotsedwa ndipo udzagwiritsidwa ntchito mwachindunji ngati mulu
Zigawo zomwe zafotokozedwa pamwambapa zikuphatikizanso ndi auger bit
1, Middle zitsulo chitoliro
2, Chitoliro chapamwamba cholumikizira
3, Chitoliro chobowola chimakhala ndi chitoliro cholumikizira chapamwamba
4. Pakati chitsulo ndodo
5. M'munsi kugwirizana kutsinde
6, Pambuyo pothamangitsidwa mobisa, muluwu pano sumachotsedwanso, koma umagwiritsidwa ntchito mwachindunji ngati mulu.
Pamaziko a "mapeto kubala mulu" dongosolo ndi "kukangana mulu" dongosolo ntchito yomanga, izo chimagwiritsidwa ntchito kwambiri pomanga zosiyanasiyana milu pansi, anangula pansi ndi mwachisawawa anamanga milu pansi.
Processing teknoloji ya mulu wozungulira pansi
Nthawi zambiri, milu yoyenerera imatha kupangidwa kudzera mu kudula, kupindika, kuwotcherera, pickling, plating yotentha ndi njira zina zaukadaulo. Pickling ndi kutentha galvanizing ndi zofunika odana ndi dzimbiri njira mankhwala, amene mwachindunji moyo utumiki wa milu yozungulira pansi.
The processing mlingo wa mulu pansi mwachindunji chimatsimikizira moyo utumiki wa zitsulo pansi mulu, monga khalidwe la osankhidwa welded chitoliro, mlingo khalidwe kuwotcherera, ngati pali maenje mchenga, kuwotcherera zabodza ndi m'lifupi kuwotcherera, zimene zonse zimakhudza tsogolo utumiki moyo wa mulu pansi ndi khalidwe la wotsatira processing. Pickling ndi yofunika kwambiri odana ndi dzimbiri ndondomeko, ndi khalidwe la plating otentha, monga nthawi plating otentha ndi khalidwe la mankhwala pamwamba, zonse zimakhudza khalidwe pansi mulu odana ndi dzimbiri mankhwala. Nthawi zambiri, mulu wa pansi wozungulira ukhoza kugwiritsidwa ntchito kwa zaka 40-80. Chilengedwe ndi njira yogwiritsira ntchito njira yogwiritsira ntchito imakhudzanso moyo wautumiki wa mulu wa pansi, monga mlingo wa acid-base wa nthaka, ngati njira yogwirira ntchito ndi yoyenera, ndipo kugwiritsa ntchito molakwika kungayambitse kuwonongeka kwa pamwamba pa mulu wazitsulo, kuwonongeka kwazitsulo zoteteza zitsulo, kuthamanga kwa dzimbiri kwa mulu wachitsulo ndi kuchepetsa moyo wautumiki.
Kugwiritsa ntchito chidziwitso cha mulu wa spiral ground
Spiral pansi mulukaŵirikaŵiri amagwiritsidwa ntchito kulimbitsa mahema m’malo amchenga ndi kutetezera mahema kuti asauluzidwe ndi mphepo. Pa nthawi yomweyo, pansi atagwira mphamvu yaMilu ya Zitsulo zachitsuloNdi bwino kusiyana ndi mulu wamba wamba mumchenga wofewa
