Maumbirwo akasiyana ePDC cutters

Kuchera ibasa rakakosha muindasitiri yemafuta uye gasi. PDC bits (inonziwo Polycrystalline Diamond Compact bit) inowanzoshandiswa mukuchera. PDC bit imhando yebhiti rine akawanda Polycrystalline Diamond (PCD) cutters akabatanidzwa kune bit body uye anocheka nepakati pematombo nekuveura chiito pakati pevacheki nedombo.

PDC cutter chikamu chakakosha chedhiri, zvakare bhiza rekuchera. Maumbirwo akasiyana ePDC cutter anonangwa kusangana nemamiriro akasiyana ebasa. Kusarudza chimiro chakanaka kwakakosha zvikuru, izvo zvinogona kuvandudza kushanda kwako uye kuderedza mutengo wekuchera.

Kazhinji, tinogovanisa PDC cutter sepazasi:

1． PDC flat cutters

2． PDC mabhatani

PDC flat cutters anonyanya kushandiswa kuchera mabheti mumigodhi neoiri minda yekuchera. Iyo zvakare inogona kushandiswa mudhaimani musimboti bit uye PDC inobereka.

Mabhenefiti makuru ePDC cutters:

• High density (low porosity)

• High compositional & structural homogeneity

• Kupfeka kwepamusoro uye kukanganisa kupikisa

• Kugadzikana kwepamusoro kwekushisa

• Yakanakisa kuita kwese kunowanikwa mumusika

PDC flat cutter dhayamita kubva 8 kusvika 19mm ::

Izvo zvataurwa pamusoro apa ndezvevashandisi vekusarudza kubva. Panguva imwecheteyo, zvirevo zvakasiyana zvezvigadzirwa zvinogona kugadzirwa uye kugadziriswa zvinoenderana nezvinodiwa nevashandisi.

Semitemo yakawanda, makucheka makuru (19mm kusvika 25mm) ane hukasha kupfuura madiki anocheka. Nekudaro, ivo vanogona kuwedzera torque kuchinja.

Madiki anocheka (8mm, 10mm, 13mm uye 16mm) akaratidzwa kuti anoboora pamwero wepamusoro wekupinda (ROP) pane makucheka makuru mune mamwe maapplication. Imwe yekushandiswa kwakadaro ndeye limestone semuenzaniso. Mabhiti akagadzirwa ane madiki anocheka asi mazhinji acho anogona kumirisana nepamusoro pekuita kurodha.

Pamusoro pezvo, vacheki vadiki vanogadzira madiki ekucheka ukuwo macheki makuru achigadzira akakura makucheka. Kuchekwa kwakakura kunogona kukonzera matambudziko nekucheneswa kwegomba kana mvura yekuchera isingakwanisi kutakura zvicherwa kumusoro.

PDC inotakura

Kutakura kwePDC kunoshandiswa senge antifriction inotakura mota inodzika, iyo inoshandiswa zvakanyanya mumakambani ebasa remumunda wemafuta uye mafekitori emota anodzika. PDC inotakura ine mhando dzakasiyana dzinosanganisira PDC radial inobereka, PDC thrust inobereka.

Mapepa ePDC anoshingirira kupfeka. Zvichienzaniswa neyechinyakare tungsten carbide kana mamwe mabearings akaomarara, hupenyu hwemadhaimondi hurefu hwakapetwa ka4 kusvika ka10, uye anogona kushanda patembiricha yepamusoro (ikozvino tembiricha yepamusoro i233°C). Iyo PDC inotakura sisitimu inogona kutora yakawandisa mutoro kwenguva yakareba, uye yakaderera kukweshera kurasikirwa mumusangano wekutakura kunowedzera kuwedzera simba remuchina.

PDC mabhatani anonyanya kushandiswa kuDTH drill bit, cone bit, uye diamond pick.

Madhaimondi anotora anonyanya kushandiswa kumichina yekuchera, senge inoenderera mberi miner madhiramu, Longwall shearer madhiramu, mugero unobhowa michina (nhoo yemuchina hwaro, rotary drilling rig, tunneling, trenching madhiramu, zvichingodaro)

PDC mabhatani anonyanya kusanganisira:

(1) PDC domed mabhatani: anonyanya kushandiswa kuDTH drill bit.

(2) PDC conical mabhatani: anonyanya kushandiswa kune cone bit.

(3) PDC parabolic mabhatani: inonyanya kushandiswa kucheka kwekubatsira.

Kuenzaniswa netungsten carbide mabhatani, mabhatani ePDC anogona kuvandudza abrasive kuramba kanopfuura kagumi.

Kunze kweakajairwa saizi, isu tinogona zvakare kugadzira pane yako dhizaini.

Tikugashirei kuti uwane zzbetter PDC cutters, kuita kwakanakisa, kunoenderana mhando, uye kukosha kwakanyanya.
