DTH nyundo zoboola miyala zing'onozing'ono zimagulitsidwa
Mafotokozedwe Akatundu
Amapanga mabatani angapo kuti agwirizane ndi mitundu yonse ndi makulidwe amitundu yonse yotchuka ya nyundo zapansi-hole.
Zopezeka mumitundu yosiyanasiyana yamutu ndi mawonekedwe a mabatani, adapangidwa kuti apatse obowola mwayi wosankha kachidutswa kakang'ono kobowola bwino mitundu yonse ya miyala ndi mikhalidwe yapansi.
Ma bits onse apakati amapangidwa ndi chitsulo chapamwamba cha nickel alloy, chomwe chimatenthedwa kuti chipangitse malo omwe amalimbana ndi kutopa ndi kuvala.
DTH (Down to Hole) drill bit, yomwe imatchedwanso spline connection drill bit, imagwiritsidwa ntchito makamaka mumgodi waukulu (wotseguka ndi wapansi), miyala yotseguka ndi yomanga.Nyundoyo ili pansi pa dzenje lolumikizana mwachindunji ndi bowolo lomwe lili ndi splines mkati mwake.Pistoni ya nyundo imagunda pobowola zomwe zimapangitsa kuti mphamvu yoyambukira iperekedwe bwino komanso kutaya mphamvu pang'ono ndikukuya kwa dzenje.

Momwe Mungasankhire mawonekedwe a nkhope ya DTH Bits ndi Carbide Button Shape
A: Kusankha mawonekedwe a Bits
Drop Center Bit
Pamalo olowera kwambiri m'miyala yofewa mpaka yapakati-yolimba komanso yopindika.
Nkhope ya Concave
Mawonekedwe ozungulira a bit a nkhope makamaka pakupanga miyala yolimba komanso yofanana.Kuwongolera kwabwino kwa mabowo ndi mphamvu yabwino yothamangitsira.
Nkhope ya Convex
Pamalo olowera kwambiri mofewa mpaka pakati-molimba komanso kuthamanga kwa mpweya wotsika mpaka wapakati.Ndiko kukana kwambiri kutsuka kwachitsulo, komanso kukana bwino kwazitsulo zotsukira zitsulo.
Pang'onopang'ono Face Bit
Mawonekedwe a nkhope amtunduwu ndi oyenera kulimba mpaka kulimba kwambiri komanso kupangika kwa miyala yonyezimira pamapulogalamu okhala ndi kupanikizika kwa mpweya.Kulowa kwabwino kumabweretsa kukana kutsuka kwachitsulo.
B: Ikani Kusankha mawonekedwe a Carbide Button
Batani losiyana ndiloyenera pamikhalidwe yosiyanasiyana yapansi, milingo ya abrasive, PSIs ndi milingo yolowera.Nthawi zambiri, mabatani a geji akachuluka, amagwirira ntchito bwino kwambiri, makamaka mu hard rock.
Chozungulira
- Kugwiritsa Ntchito Mphamvu-zolinga zambiri
- Yoyenerana bwino ndi abrasive yofewa
- 25,000 mpaka 45,000 PSI (170 mpaka 300 MPa)
- Abrasive kuti abrasive kwambiri
Batani la Ballistic
- Mphamvu ya Ntchito- kulowa mwachangu
- Zoyenerana bwino ndi nthaka yofewa
- 10,000 mpaka 20,000 PSI (70 mpaka 140 MPa)
- Non abrasive ground
Semi-ballistic
- Kugwiritsa Ntchito Mphamvu-mwachangu kulowa
- Zoyenerana bwino ndi malo apakati
- 15,000 mpaka 25,000 PSI (100 mpaka 170 MP)
- Pang'ono abrasive nthaka
Batani Loweta (Conical).
- Mphamvu ya Ntchito- kulowa mwachangu
- Zokwanira pamitundu yonse yapansi yosawonongeka
- Malo ocheperako
- Zoyenerana bwino ndi tizigawo tating'onoting'ono
Mawonekedwe a zitsulo za Nickel-alloy zitsulo
1) Kudalirika
Pistoni ya DTH Hammer imagwiritsa ntchito chitsulo chapadera (chotumizidwa) chapamwamba cha nickel alloy, chokhala ndi kutentha kwapamwamba monga muyezo wamakampani ankhondo.
Kulimbitsa processing pa nyundo pamwamba anali-kukana.
2)Kukwanira
Zobowola mwapadera zopangira miyala yapakatikati ndi yolimba.Chosavuta disassembly ulusi kuti zosavuta kukonza.
3) Kuchita bwino
Kapangidwe kakapangidwe kakafupi ka DTH nyundo ndi pang'ono kuti igwire bwino ntchito yotumiza mphamvu kwambiri, yokhala ndi mphamvu zambiri komanso kukumba mwachangu.
Mapangidwe a nyundo ndi pang'ono amakongoletsedwa ndi kayeseleledwe ka makompyuta, okhala ndi chipinda chabwino kwambiri chogawa mpweya komanso kapangidwe ka mpweya wothina.
