ZINTHU ZOPEREKERA MANO
IADC 1 SERIES DRILL BITS
Ma bits awa amagwiritsidwa ntchito kubowola mphamvu zochepetsetsa, zofewa.Mano otalikirapo amatalika amagwiritsidwa ntchito pama cones okwera kuti apereke mitengo yolowera kwambiri yotheka.Zolimba zosamva kuvala zimagwiritsidwa ntchito poletsa kutha kwa mano.Pa mitundu yofewa kwambiri, cholimbacho chimakwiriratu mano.
IADC 2 SERIES DRILL BITS
Izi zing'onozing'ono zimagwiritsidwa ntchito pobowola zolimba komanso zowononga.Mano aafupi kwambiri, otalikirana kwambiri okhala ndi zomangira zolimba kwambiri amagwiritsidwa ntchito pofuna kusweka.Ma bits awa ayenera kupirira akalemedwa kwambiri ndi kubowola mapangidwe abrasive ndi kuphwanya, kudula.

Malangizo ogwiritsira ntchito ma roller cone bits:
1 .Pamaso pobowola pansi, m'pofunika kutsimikizira kuti pansi pa chitsime ndi choyera, chopanda grit, ndipo palibe chitsulo chogwa.
2. Chongani ngati ulusi kugwirizana screw wa chodzigudubuza chulu pang'ono pang'ono ndipo nozzle anaika bwino.
3. Kuthamanga mu dzenje kuyenera kukhala kokhazikika, kupewa kupsinjika ndi kupewa kubowola.
4. Cholumikizira chomaliza chimafunikira kusamutsidwa kwakukulu kuti muyambitse tebulo lozungulira ndikupitilirabe mpaka pansi pa chitsime., Tsukani bwino chitsimecho kuti zinyalala zisatseke mphuno.
5. Mawonekedwe a dzenje lapansi ayenera kukanikizidwa mopepuka ndikutembenukira pang'onopang'ono kuti agwirizane ndi pansi pa chitsime, kuthamanga kwazing'ono, kuthamanga kwapansi, kusuntha kwakukulu, torque yaying'ono, ndi liwiro la 40 ~ 60 rev / min, osachepera 30. mphindi.
6. Dziwani kulemera kwa pang'onopang'ono ndi liwiro limodzi ndi zochitika zenizeni za mapangidwe.
7. Pobowola kutsogolo, ntchitoyo iyenera kukhala yosalala, kudyetsa kubowola kuyenera kukhala kofanana, ndikoletsedwa kukweza ndi kumasula chobowola mwamphamvu, chingwe chobowola sichimabowola bwino ndi chingwe chobowola popanda kugwa.
8. Zikapezeka kuti kubowola kumasiya kupita patsogolo, kuthamanga kwa pampu kumawonjezeka ndikuchepa mwachiwonekere, mlingo wa kulowa mkati umachepa mwadzidzidzi, ndipo torque ikuwonjezeka, kwezani kubowola kuti muwone popanda kuchedwa.
