Iwo maviri Akakosha Zvishandiso zvePDC Cutters

PDC cutter imhando yemhando yepamusoro-yakaoma zvinhu iyo compact polycrystalline diamondi ine tungsten carbide substrate pa-ultra-high tembiricha uye kudzvanywa.

PDC Cutter yakagadzirwa kutanga neGeneral Electric (GE) muna 1971. Yekutanga PDC Cutters yeindasitiri yemafuta uye gasi yakaitwa muna 1973 uye mushure memakore matatu ekuedza uye kuongororwa kwemunda, inopupurirwa kuti inoshanda zvakanyanya kupfuura zviito zvekupwanya zve carbide. mabhatani mabheti saka anounzwa zvekutengesa muna 1976.

PDC Cutters akagadzirwa kubva tungsten carbide substrate uye synthetic diamond grit. Iyo diamondi uye carbide substrate inokura pamwechete kuburikidza nemakemikari zvisungo pasi pepamusoro-tembiricha uye high-pressure mamiriro.

Izvo zvakanyanya kukosha zvePDC cutters ndeye diamond grit uye carbide substrate.

1. Gira redhaimani

Diamond grit ndiyo yakakosha zvinhu zvePDC cutters. Panyaya yemakemikari uye zvivakwa, manmade diamond yakafanana nedhaimondi rechisikigo. Kugadzira grit yedhaimani kunosanganisira maitiro akareruka emakemikari: yakajairwa kabhoni inodziiswa pasi pekumanikidza kwakanyanya uye tembiricha. Mukuita, zvisinei, kugadzira dhaimani hakusi nyore.

Dhaimondi grit haina kugadzikana pakupisa kwakanyanya kupfuura dhaimondi rechisikigo, zvisinei. Nekuti simbi inokonzeresa yakavharirwa muchimiro chegrit ine mwero wepamusoro wekuwedzera kwemafuta kupfuura madhaimani, mutsauko wekuwedzera unoisa madhaimani-kune-dhaimani mabhondi pasi peshear uye, kana mitoro yakakwira zvakakwana, inokonzeresa kutadza kwemabhondi. Kana zvisungo zvikaramba, madhaimondi anokurumidza kurasika, saka PDC inorasikirwa nekuoma kwayo nekupinza uye haishande. Kudzivirira kutadza kwakadaro, PDC cutters inofanirwa kutonhodzwa zvakaringana panguva yekuchera.

2. Carbide substrate

Carbide substrate inogadzirwa ne tungsten carbide. Tungsten carbide (kemikari formula: WC) ikemikari inosanganiswa ine tungsten uye kabhoni maatomu. Iyo inonyanya kukosha yetungsten carbide ipfumbu yehupfu, asi inogona kudzvanywa uye kuumbwa kuita maumbirwo kuburikidza nekutsikirira uye sintering.

Tungsten carbide inoshandiswa zvakanyanya mukuchera zviboorero zvedombo repamusoro, sando dzepasi, magejo egejo, mapikicha egejo refu, mapikicha ekugera, kusimudza zvinofinha, nemichina inofinha.

Zzbetter ine kudzora kwakasimba kune mbishi zvinhu zve diamond grit uye carbide substrate. Pakugadzira iyo PDC cutter oilfield yekuchera, isu tinoshandisa dhaimondi rinotengeswa kunze kwenyika. Isu tinofanirawo kuipwanya uye kuigadzira zvakare, zvichiita kuti saizi yepakati iwedzere kufanana. Tinofanirawo kuchenesa madhaimani. Isu tinoshandisa Laser Particle Size Analyzer kuongorora iyo particle size kugovera, kuchena, uye saizi yebhechi yega yega yedhaimani poda. Isu tinoshandisa emhando yepamusoro mhandara hupfu ane mamakisi akakodzera kugadzira tungsten carbide substrates.

PaZzbetter, tinogona kupa huwandu hwakasiyana hweakatemerwa chaiwo.
