STEEL panggilingan waos bit
IADC 1 SERIES pengeboran bit
Bit iki digunakake kanggo pengeboran kekuatan kompresi rendah, tatanan alus.Dawane untu proyeksi dawa digunakake ing kerucut offset dhuwur kanggo nyedhiyakake tingkat penetrasi paling gedhe.Wear-resistant hardfacing digunakake kanggo ngontrol nyandhang untu.Ing jinis bit sing paling lembut, hardfacing iki nutupi untu bit.
IADC 2 SERIES pengeboran bit
Bit iki digunakake kanggo pengeboran tatanan hard lan abrasive.Gigi sing cendhak banget, jarak sing rapet kanthi jumlah hardfacing minimal digunakake kanggo tahan patah.Bit iki kudu tahan beban sing dhuwur lan ngebor formasi abrasif kanthi aksi ngremuk lan nglereni.

Cathetan kanggo nggunakake bit rol cone:
1 .Sadurunge pengeboran mudhun, perlu kanggo mesthekake yen dhasar sumur resik, ora ana grit, lan ora ana logam sing tiba.
2. Priksa manawa sekrup sambungan benang saka bit kerucut roller utuh lan nozzle dipasang kanthi bener.
3. Run ing bolongan kudu stabil, supaya kaku lan nyegah ngebur.
4. Sendi pungkasan perlu pamindahan gedhe kanggo miwiti Tabel Rotary lan terus reaming kanggo ngisor sumur., kanthi wisuh sumur kanggo nyegah lebu saka clogging nozzle.
5. Wangun bolongan ngisor kudu entheng dipencet lan alon-alon nguripake menyang kontak karo ngisor sumur, meksa pengeboran cilik, kacepetan kurang, pamindahan gedhe, torsi cilik, lan kacepetan 40 ~ 60 rev / min, paling 30 menit.
6. Nemtokake bobot ing bit lan kacepetan ing kombinasi karo kahanan nyata tatanan.
7. Sak ngebur ahead, operasi kudu Gamelan, pengeboran dipakani kudu seragam, iku strictly pareng angkat lan ngeculake pengeboran banget, senar pengeboran ora uga braked lan pengeboran senar free tiba.
8. Yen wis ketemu sing dicokot pengeboran mandheg nggawe kemajuan, mundhak meksa pump lan sudo temenan, tingkat seng nembus dumadakan sudo, lan torsi tambah, angkat bor kanggo mriksa tanpa wektu tundha.
