Sumo pfupi yePDC cutters

 

Dhizaini yePDC drill Bits yanhasi sematrix haina kufanana neyaimbovepo makore mashoma apfuura. Simba rekusimba uye kuramba kusimba kwakawedzera ne33%, uye simba remabraze ekucheka rakawedzera ne ≈80%. Panguva imwe chete, majometri uye tekinoroji yezvimiro zvinotsigira zvavandudzwa, zvichikonzera zvigadzirwa zvematrix zvakasimba uye zvinobudirira.
Zvinhu zvekucheka
Zvicheki zvePDC zvinogadzirwa necarbide substrate nedhaimani. Kupisa kwakanyanya kwemadigirii 2800 uye kumanikidzwa kwakanyanya kweinenge 1,000,000 psi zvinoumba chidimbu ichi. Cobalt alloy inoshandawo sechinhu chinobatsira pakuita kuti sintering iite. Cobalt inobatsira kubatanidza carbide nedhaimani.
Huwandu hweVatemi
Tinowanzo shandisa ma cutters mashoma pazvidimbu zvePDC zvakapfava sezvo cutter yega yega ichibvisa kudzika kukuru kwekucheka. Kuti zvive zvakaoma, zvakakosha kushandisa ma cutters akawanda kuti zvikwanise kudzika kudiki kwekucheka.

 

PDC Drill Bits - Saizi Yekucheka
Kuti zvive zvakapfava, tinowanzo sarudza kucheka kwakakura pane mune zvakaoma. Kazhinji, saizi dzakajairika dzinobva pa8 mm kusvika 19 mm pane chero chinhu.

 

 

Tinowanzo tsanangura dhizaini yedhizaini ye cutter rack nekutarisa kumashure kweraki uye makona erivhari repadivi.
●Cheka chemusana chekucheka ndiyo kona inoonekwa nechiso checheka kusvika pakuumbwa kwayo uye inoyerwa kubva pakamira. Makona echeka chemusana anosiyana pakati, kazhinji, 15° kusvika 45°. Haachinji pakati pechidimbu, kana kubva pachidimbu kuenda pachidimbu. Hukuru hwekona yecheka chekucheka yePDC drill bits hunokanganisa Penetration Rate (ROP) uye kuramba kwecheka. Sezvo angle yecheka ichiwedzera, ROP inoderera, asi kuramba kwecheka kunowedzera sezvo mutoro wakashandiswa ikozvino wapararira panzvimbo yakakura zvikuru. Vacheki vePDC vane macheka madiki emusana vanotora kudzika kukuru kwekucheka uye nekudaro vanowedzera kusimba, vanogadzira Torque yakakwira, uye vanokurumidza kupera uye njodzi huru yekukuvara.

 

 

●Rake yerutivi rwekucheka inoyera zvakaenzana kurongeka kwemuchina wekucheka kubva kuruboshwe kuenda kurudyi. Makona erutivi rwekucheka anowanzova madiki. Akona yerutivi rwekucheka inobatsira kuchenesa maburi nekutungamira zvidimbu zvakananga kuannulus.
