Ko te nuinga o te wā, he mea hanga te mata keri PDC mā te whakamahi i ngā taputapu tapahi PDC me te maitai, ā, nā te kaha o te maitai ki te pā me te ātete ki te kakahu o te taimana polycrystalline, ka tere ake te keri o te mata keri PDC i roto i te tukanga keri. He tere ake te keri o te mata keri PDC tinana maitai i roto i te hanganga ngohengohe, engari he ātete ake te keri o te mata keri PDC tinana matrix ki te kakahu, ka taea e te mata keri tinana matrix te keri i te hanganga mārō ina whakaritea ki te mata keri PDC tinana maitai nā te mea he tinana matrix tungsten carbide, engari he puhoi ake te keri ina whakaritea ki te mata keri PDC tinana maitai. Mena kei te hiahia koe ki tētahi o ngā mata keri PDC, tēnā whakapā atu ki a Far Eastern Drilling.
Ngā Momo PDC Tinana Matrix vs. Ngā Momo PDC Tinana Rino
Mena kua roa koe e mahi ana i te keri, kua rongo pea koe mō ngā mata PDC. Ko te PDC he whakarāpopototanga mō te "polycrystalline diamond compact," e whakaahua ana i te rauemi e hanga ana i te mata tapahi o ēnei mata. He mea hanga te Matrix Body PDC me te Steel Body PDC ki tēnei matū.
He maha ngā ingoa mō ēnei wahi. E mōhiotia whānuitia ana rātou:
- Ngā Momo PDC
- Ngā moka taimana polycrystalline
- Ngā moka niho maramara hiato
- Ngā poraka tapahi taimana polycrystalline
He maha ngā wā ka whakamahia ngā mata PDC mō te keri hinu – engari he rongonui anō hoki i roto i ētahi atu ahumahi. I hangaia i te tau 1976, ā, he rite tonu te rongonui o ēnei ināianei kingā moka kōne-roera(te momo mata he wāhanga hurihuri). Ahakoa he roa te hītori o te angitu o ngā mata PDC, kei te whanake tonu, kei te whakapai tonu mā roto i ngā koki tapahi hou, ngā whakaritenga, me ngā rauemi. He tino whai hua ēnei mata i a rātou e mahi ana ki te kutikuti i ngā hanganga toka, kaua ki te kuru. I ia tau, ka whakapai ake ngā whanaketanga hou o te hangarau i te whai huatanga o ngā mata PDC me te whakapai ake i te tere keri.
E mōhiotia ana ēnei mata ko ngā mata "mai i te ihu ki te kōhatu huri" o te umanga keri – ka oti pai te mahi, ā, he tino whai hua hoki mō te whānuitanga o ngā ratonga me ngā momo hanganga—kāore he wāhanga neke e piri, kāore he ngangau, he keri whai hua noa iho mō ō hiahia katoa.
He aha ngā Momo PDC?
E rua ngā momo matua oNgā mata keri PDC– ngā mata PDC tinana matihiko me ngā mata PDC tinana maitai. He rite te āhua o ngā mata porowhita e rua, e whā ki te waru ngā hanganga tapahi, ngā mata rānei, e horapa ana mai i waenganui. Kātahi ka tāpirihia he mata tapahi tekau ki te toru tekau ki runga i ia mata. He awa wai kei ngā mata hei whakamatao, ā, he pūwero kei te pito o te mata. Ki te whakaaro koe ki tēnei mata, he rite tonu te āhua ki te karauna e mau ana te kingi.
E whakamahia ana ngā mata PDC mō te keri hinu me te hau, te keri waiariki, te keri puna wai, te keri hangahanga, te keri maina me te keri ahunga whakapae.
Te Pūtaiao kei Muri i ngā Moka PDC
Tērā pea kua ako koe i te kura ko te taimana te rauemi tino mārō e mōhiotia ana e te tangata. Ae! Ā, he tino pai mō te tapahi i ētahi atu rauemi pēnei i ngā hanganga toka mō te keri.
Ka whakamahia e ngā mata PDC ngā taimana iti, iti te utu, i hangaia e te tangata i roto i ā rātou hanganga tapahi. He uaua te tukanga hanga taimana i runga i ēnei mata. Hei whakangawari ake, anei te tukanga mō te hanga mata keri taimana:
- Ka hangaia ngā taimana hangai iti
- Kātahi ka whakakotahihia ngā taimana hei puranga nui o ngā tioata
- Kātahi ka hangaia ngā tioata kia rite ki ngā tēpu taimana
- Kātahi ka herea ngā tēpu taimana ki te konganuku, ko te tikanga he tungsten carbide, me te here konganuku.
- Ka noho tēnei hei wāhanga tapahi o te mata – he maha ngā tapahi i ia mata o te mata
- Kātahi ka tāpirihia ngā kaitapahi ki ngā mata, ka tāpirihia ki te tinana o te mata.
Ka whakamahia ngātahitia ngā kaitapahi me ngā mata i te pito o te mata PDC hei tapahi i ngā momo toka katoa.
Taimana Hanga i roto i ngā Moka Wiri
E kite ana koe, ko ngā taimana hangai te rauemi matua mō ngā mata PDC. I te hanga i ēnei mata, ka hangaia he kirikiri taimana tino iti (e kiia ana ko te kirikiri taimana). He tino pakari tēnei kirikiri engari ka iti ake te pumau i te taumata ngota ina wera. Nō reira, he nui ake te tūponotanga ka pakaru tō mata PDC mena kāore i te pai te whakamatao i te wā e whakamahia ana.
Ahakoa rā, he tino ātete ngā taimana hangai ki te kakahu; koinei te rauemi tino pai mō te roa o te wā me te pakari. Ka rerekē te momo whakarewa mēnā ka whiriwhiria e koe he mata whakarara, he mata maitai rānei – engari he mea nui te taimana. Ka roa te ora o ngā mata PDC mēnā ka whakamataohia.
Ngā Momo PDC Tinana Matrix
Ko ngā mata o te tinana Matrix tētahi o ngā momo mata PDC rongonui. He mea hanga ēnei ki tētahi rauemi hiato he mārō, he pakarukaru hoki. He mea hanga te rauemi ki ngā konganuku tungsten carbide kua herea ki tētahi mea here whakarewa ngawari ake, pakari ake. Ahakoa kāore i te tino kaha ngā mata o te tinana Matrix ki ngā pānga, he pai ake te ātete ki te pakū i ngā mata PDC tinana maitai.
Ka hangaia ngā wahi tinana matihiko mā te whakamahi i tētahi pokepokea ai kua werahia i roto i te oumu. Ka whakakīia te pokepokea ai ki te konganuku whakarewa hei āhua totoka, ka whakamahanahia kia rewa, ka whakamatao, kātahi ka huihuia ki ngā taputapu tapahi.
Ngā Whakamahinga o ngā Momo PDC Matrix Body
Ko ngā moka PDC tinana matrix te mea matua e whakamahia ana mō ēnei mahi:
- Ngā hanganga ngohengohe ki te pakeke-waenga
- Te nui o te rōrahi
- Oneone teitei
- Ngā tono e hiahiatia ana te whakamahi i te moka kotahi mō ngā oma moka maha
Ngā Momo PDC Tinana Rino
Ko ngā mata PDC tinana rino tētahi atu o ngā momo mata PDC tino noa. He rerekē te hanganga o ēnei mata ki te mata matrix. He mea hanga ēnei ki te rino, kaua ki te konganuku hiato e whakamahia ana mō ngā mata PDC tinana matrix. He tino pai ki te ātete ki te pānga engari he nui ake te tūponotanga ka pakaru i te horo.
Ka whakamahia e ngā mata PDC maitai te mahi tapahi o te mata hei wawahi i te toka e keria ana ki roto. He tino pumau te nuinga o ēnei, ā, ka taea te keria i ngā tere teitei.
He mea hanga ēnei poro ki ngā pae rino. Ka mīhinihia ngā pae ki ngā mira me ngā mīhini hurihuri whakarewa hei hanga i te tinana o te poro, kātahi ka whakapirihia ngā niho tapahi me te pou ki reira. He māmā ake te hanga i ngā poro rino PDC ki ngā āhua me ngā hoahoa uaua. Mā te hanga hoahoa uaua ka taea te whānuitanga o ngā mata tapahi me ngā āhuatanga. He pai te rerekētanga o ngā āhuatanga tapahi i te wā e keri ana i ngā hanganga toka ahurei.
Ngā Whakamahinga o ngā Mīti PDC Tinana Rino
He whai hua ngā mata PDC tinana maitai mō ngā mahi penei:
- Te keri i ngā hanganga kirikiri
- Ngā wāhi kōhatu ngohengohe
- Te keri tere i roto i te paparanga
- Te keri hau māori
- Ngā puna hohonu
- Ngā hanganga whakakoi
Hokona ngā PDC Bits Ipurangi
He mahi uaua te whiriwhiri i tētahi kaiwhakarato mō ngā mata PDC. Ahakoa he maha ngā kōwhiringa pai hei whiriwhiri māu, he kaiwhakarato mātau a Far Eastern Driling Bit, ā, he nui rawa atu āna taonga i Haina. Ka taea e koe te mōhio atu ki ētahi atu kōrero mai i te paetukutuku www.chinafareastern.com
