Umbhobho woKwemba kakuhle

Inkcazelo emfutshane:

Umbhobho wokugrumba, uhlobo olufutshane lombhobho wokugrumba umngxuma, luhlobo lwentonga yokomba engaphandle.Isetyenziswa ikakhulu kwi-rotary percussive drilling equlethe iigesi kunye nolwelo.Amacandelo ayo aphambili abandakanya umbhobho (intonga) umzimba kunye nokudibanisa.

Umyalezo I-imeyile

Iinkcukacha zeMveliso

Iithegi zeMveliso

Imibhobho Drill isetyenziswa ngokubanzi kwimigodi, ukuhlola ngokwejoloji kunye nazo zonke iintlobo zokomba (amanzi, ioyile, igesi, njalo njalo) project.As a okhokelayo ukuvelisa umbhobho yokomba, senza zonke iintlobo zemigangatho kunye non-standard imibhobho yokomba kubathengi bethu.Imibhobho yethu yokomba ibandakanya umbhobho wokomba wentsimbi, umbhobho wokomba wemigodi, umbhobho wokomba wamanzi, umbhobho wokomba we-oyile, umbhobho wokugaya i-API, intonga yokubhola i-DTH, intonga yokubhola, njl njl.

Iimpawu eziphambili ze-tube ye-DTH ephezulu zizinzileyo, ukuchaneka kunye nokulawula.

Umbhobho woQhaphaza :

1.Umzimba wombhobho: umbhobho obandayo wozoba umthungo ongenamthungo.ngoko ke umbhobho unobungakanani obuchanekileyo, i-centerizer elungileyo.
2.Impahla yomzimba wombhobho ikwibakala elifanayo neleSandvik.
3.Isinxibelelanisi soMsonto : Ubushushu kunye nonyango lwe Nitrogen , ngoko ke umbhobho womelele kwaye kulula ukuwulayisha nokuwukhulula .
4.I-Friction welding.

Umbhobho wokomba weDTH oMgangatho:

Ububanzi: 76mm, 89mm, 102mm, 114mm, 127mm, 140mm;

Ubude: 1000mm, 1500mm, 2000mm, 3000mm, 5000mm, 6000mm;

Umsonto: 2 3/8” API REG, 2 7/8” API REG, 3 1/2” API REG, 4 1/2” API REG,

2 3/8 API IF, 3 1/2 API IF
