Kudzora kwemhando yePDC cutters

Iwo maPDC cutters ane Polycrystalline Diamond layer uye carbide substrate. PDC cutters inodaidzwa zvakare kuti Polycrystalline Diamond Compact cutters, inova rudzi rwezvinhu zvakaoma zvikuru. Iko kushandiswa kwepolycrystalline diamond compact (PDC) cutters kuri kupararira zvakanyanya mazuva ano nekuda kwekuita kwavo kwepamusoro uye kusimba munzvimbo dzakaoma.

Izvo zvakakoshesesa zvinhu zvePDC vanocheka muoirifield yekuchera application mhando uye kuenderana. Ndinotenda kuti munhu wese achabvuma. Asi sei kudzora kunaka?

Kuve nechokwadi chese chidimbu chePDC cutter chinouya ZZZVAKANAKAmaoko emutengi ane mhando yepamusoro, ZZZVAKANAKAyakagadzira yakasimba yemhando yekudzora hurongwa, inosanganisira kudzora zvinhu, kugadzirwa kwemaitiro, uye kupedzwa zvigadzirwa kutonga. Mushandi wedu akadzidziswa zvakanyanya uye ane hunyanzvi uye akazvipira. Imwe neimwe PDC cutter inovakwa nevashandisi vakadzidziswa zvakanyanya uye kudzvanywa kunodzorwa mumashina panguva yekupisa.

PDC cutter quality control：

1. Raw material

2. Nzira yekugadzira

3. Kuongororwa kwezvinhu zvakapedzwa

1. Raw material control

1.1 Pakugadzira iyo PDC cutter oilfield drilling application tinoshandisa dhaimondi rinotengeswa kunze kwenyika. Isu tinofanirawo kuipwanya uye kuigadzira zvakare, zvichiita kuti saizi yepakati iwedzere kufanana. Tinofanirawo kuchenesa madhaimani.

1.2 Isu tinoshandisa Laser Particle Size Analyzer kuongorora kugoverwa kwesaizi, kuchena uye saizi yebhechi rega rega rehupfu hwedhaimani.

1.3 Kune tungsten carbide substrate isu tinoshandisa iyo giredhi chaiyo ine yakanyanya kusimba kuramba.

2. Nzira yekugadzira

2.1 Tine nyanzvi inoshanda uye zvivakwa zvepamberi kugadzira iyo PDC cutters

2.2 Munguva yekugadzira isu tichatarisa tembiricha uye kudzvanywa mune chaiyo-nguva uye kugadzirisa nenguva. Tembiricha ndeye 1300 - 1500℃. Dzvinyiriro ndeye 6 - 7 GPA. Iyo HTHP inodzvanya.

Kugadzira chidimbu chimwe chePDC Cutters chinoda kutenderera maminetsi makumi matatu.

Kune yega yega batch yePDC cutters, chidimbu chekutanga chakakosha. Pamberi pekugadzirwa kwehuwandu, isu tichaongorora chikamu chekutanga kuti tione kuti chinosangana nezvinodiwa nemutengi pakukura nekuita.

3.Kuongorora kwezvigadzirwa zvakapedzwa

Kuti tive nechokwadi chekuti vese vePDC vanocheka vanokodzera uye vanowirirana, hatifanire kungo nyatso kudzora ongororo yezvigadzirwa uye kugadzirwa kweyekuyerera uye kuvandudza tekinoroji, isu tinofanirawo kuzvipira kuvaka marabhoritari ine zvivakwa zvekuyedza zvepamberi kutevedzera mamiriro ekuchera munhandare yemafuta uye kuyedza PDC cutter pafekitori. tisati taendesa kune vatengi vedu.

Kupedzwa kwechigadzirwa kutonga isu tichaita kubva pazasi maficha:

Saizi uye chitarisiko chekuongorora

Kudzora kukanganisa mukati

Performance test

3.1 Saizi uye chitarisiko chekuongorora:dhayamita, kureba, dhaimani ukobvu, chamfer, geometric saizi, kutsemuka, dema dema, nezvimwe.

3.2 Kudzora kukanganisa mukati

Kudzora hurema hwemukati isu tichashandisa iyo yepamusoro inotengeswa kunze kwenyika ultrasonic C-san yekuongorora michina. Kune mafuta akaiswa PDC cutters isu tinofanirwa kuongorora zvidimbu zvese.

Iine C-scanning system, ultrasonic wave inogona kupinda muPDC layer uye kuona delamination kana mhango kuremara. C-scanning system inogona kuona saizi uye chinzvimbo chekuremara uye kuvaratidza paPC skrini. Zvinotora anenge 20minutes kuita imwe nguva yekuongorora.

3.3 PDC Cutter's performance sampling test:

kupfeka kuramba

kukanganisa kupikisa

kugadzikana kwekupisa.

3.3.1 Wear Resistance Testing:nekuyera kuti mangani maremu akarasika mushure mevacheki vePDC vakagadzika giraniti mune imwe nguva yenguva, tinowana chiyero chekupera. Iko kurasikirwa kukuru pakati pePDC cutters uye granite. Iyo yakakwirira iyo reshiyo, iyo inowedzera kupfeka kuramba iyo PDC Cutters ichave.

3.3.2ImpactResistance Test:Isu tinoidaidza zvakare Drop-Weight bvunzo, tichishandisa yakatwasuka lathe pane imwe kureba ichirovera paPDC Cutter yekucheka mbiri, kazhinji ine imwe dhigirii (15-25 dhigirii) siraidhi. Huremu hweiyi vertical lathe uye kureba kwayo kwakagara kwaizoratidza kuti inokunda sei iyi PDC cutter ingave.

3.3.3 Thermal Stability Test:Inotarisirwa kuyedza kana PDC Cutters yakagadzikana inodziya zvakakwana pasi pekushisa kwakanyanya kwekushanda. Kurabhoritari, tinoisa PDC cutters pasi pe700-750℃mumaminetsi gumi-gumi nemashanu uye ongorora mamiriro edhaimondi mushure mekutonhora kwechisikigo mumhepo. Kazhinji maitiro aya anoperekedzana neimwe kupfeka kuramba uye kukanganisa kuramba kuenzanisa mhando yePDC cutter isati yaedzwa uye mushure mekuedzwa.
