The screw ground mulundi mulu wobowola pansi, womwe umadziwika kuti umakhala ndi pobowola ndi chitoliro chobowola, ndipo pobowola kapena chitoliro chobowola chimalumikizidwa ndi cholumikizira gwero lamphamvu;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 onyamula mulu" dongosolo ndi "kukangana mulu" dongosolo mu ntchito yomanga, 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 limatsimikizira moyo utumiki wa zitsulo pansi mulu, monga khalidwe la osankhidwa welded chitoliro, mlingo khalidwe kuwotcherera, ngati pali mchenga mabowo, kuwotcherera zabodza ndi m'lifupi kuwotcherera, amene onse zimakhudza moyo wamtsogolo wautumiki wa mulu wapansi ndi ubwino wa processing wotsatira.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 mulu pansi mankhwala odana ndi dzimbiri.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 digiri ya acid-base ya nthaka, ngati njira yogwirira ntchito ndi yoyenera, ndipo kugwiritsa ntchito molakwika kungayambitse kuwonongeka kwa pamwamba pa nthaka. zitsulo pansi mulu, kuwonongeka kwa zitsulo zoteteza wosanjikiza, mathamangitsidwe wa dzimbiri pansi zitsulo mulu ndi kuchepetsa moyo utumiki.
Kudziwa kugwiritsa ntchito 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 Yachitsulo YachitsuloNdi bwino kusiyana ndi mulu wamba wamba mumchenga wofewa
