Ukubhoboza amalahle manje sekuvame ukusetshenziswa embonini yokumba izinto ezintathu, amandla ahlukaniswe izigaba ezimbili, UHLOBO I lokugaya amatshe athambile, uhlobo lwe-II lwamatshe aqinile kanye nokumba amatshe aqinile.Ngesivinini esisheshayo sokumba, ukumbozwa okubanzi kokugaya, ukonga isikhathi, ukonga umzamo, ukusebenzelana okulula, okuhlala isikhathi eside nezinye izici ezivelele.Ingcezu yamalahle isetshenziswa lapho kumbiwa amalahle athambile, umgwaqo wamalahle aqinile kanye namatshe amalahle.Ngezansi kwemboni yehlathi yase-Zhengzhou i-xiaobian ukwethula ukuhlukaniswa nokusetshenziswa kokubhola kwamalahle.
1. Imininingwane namamodeli wezinhlamvu zokumba amalahle
Ukucaciswa kwebhithi yamalahle namamodeli ahlukaniswe abe ngu-ф 28mm, ф 30mm, ф 32mm, ф 38mm, ф 42mm ngokobubanzi bosayizi wamaphiko amabili.
2. Ukuhlelwa kwezingcezu zokubhola amalahle
Ngokwemodi yokusebenza ayifani, ukubhola kwamalahle kungabuye kuhlukaniswe ukuhlolwa okomile kanye nokuhlolwa okumanzi okubili.I-Dry test bit incane enganikezi amanzi othuli futhi ayinawo umgudu wokuphepha wokuhlinzeka ngogesi kuyo yonke inqubo yokumba.Ibhithi yokuhlola emanzi: ingxenye enamanzi anothuli anikezwa ngesikhathi sokumba yonke kanye nephaseji eliphephile lokuphakelwa kukagesi.Ngokusho kwezinto ezimbili zamaphiko azifani, i-bit yamalahle ihlukaniswe i-carbide cutter bit kanye ne-diamond composite sheet (PDC) bit.
3, ukusetshenziswa okuyinhloko komshini wamalahle
Kufakwe endaweni yokumba ikhemikhali yamalahle, isihluthulelo sokumba imbobo ethambile - ye-hard rock reinforcement bolt yokusekela imbobo.Ngokuvamile isetshenziswa emgwaqeni wamalahle ngamandla edwala F ≤8, ikakhulukazi emsebenzini wokusekela ibhawodi womgwaqo wamalahle, ingabhoboza imbobo yekhebula lehange le-cast-in-place slab.
E-China, insimu yamalahle inezici ezilandelayo: okokuqala, umthamo wemakethe, ngoba i-bit yamalahle isetshenziswa embonini yokumba amalahle, indawo ephakathi nendawo ephansi yesidingo inkulu kakhulu;Okwesibili, inani eliphelele lamabhizinisi akhiqizayo likhulu, futhi izinga lokusebenza lincane, lisakazeke kakhulu, futhi ukugxilwa kwemboni kuphansi.
Ngenhla ithi "yini ukuhlukaniswa kwebhithi yamalahle nokusetshenziswa kwayo?"Ngethemba ukuthi ngingakusiza.Uma ufuna ukwazi kahle okuqukethwe kwezinye izinto zokusebenza zezimayini, ungakwazi ukunaka le webhusayithi, kodwa futhi uthintane nenkonzo yethu yamakhasimende aku-inthanethi, senza konke okusemandleni ethu ukukusiza.
