Kuita kwePDC cutters

Tsvagiridzo nekuvandudzwa kwePDC cutters zvakagadziridzwa munyika zhinji muma1970s. Mumiriri ndiye "stratapax" nekambani yeGE, Iyo "syndrill" nekambani yeDeBeers, uye "Claw Cutter" naSandvik.

Kuita kwevacheki vePDC vari pamusoro, zvisinei nekuramba kupfeka, kusimba kwemaitiro, kana kugadzikana kwemafuta, zvese zvinomiririra danho repamusoro repasi panguva iyoyo.

Kuita kwePDC cutter inonyanya kureva zviratidzo zviri pasi apa:

1. Kuramba kupfeka (kunonziwo wear ratio),

2. Anti-impact kusimba (joule),

3. Kugadzikana kwekupisa

Mushure menguva hombe yekuyedzwa kwePDC cutter, takaona mwero wePDC cutters munyika yedu senge pazasi:

Pakati pe-1990s kusvika 2003: kupfeka kuramba ndeye 8 kusvika ku120,000 (10 kusvika 180,000 kunze kwenyika);

Iko kukanganisa kuoma ndeye 200 ~ 400 j (kupfuura 400 j kunze kwenyika).

Shanduko mukugadzikana kwekupisa ndeye: mushure mekunyura pa750 ° C (pasi pemamiriro ekuderedza), iyo Wear reshiyo inoratidzwa ichikwira ne5% kusvika 20% kune vamwe vagadziri vepamba, uye kuoma kwemhedzisiro hakuna shanduko huru. Vamwe vagadziri varamba pachiyero chekupfeka uye anti-impact kuoma.

Kupfupisa, kuoma, kusakara, kusasimba, uye kugadzikana kwekupisa kwevacheki vePDC venyika yedu kwaswedera uye kusvika padanho repamusoro repasi rose, zvichiisa hwaro hwekuwedzera kuchera mumatombo akaomarara ane PDC anocheka.

Isu tinodaidza iyo PDC yekucheka nekuomarara kwepamusoro, kupfeka kwakanyanya kuramba, kusimba kwakanyanya, uye kugadzikana kwepamusoro kwemafuta mana-akakwira PDC anocheka. Kuchera nemhando yepamusoro PDC cutters kunofambisa budiriro yakazara yemapurojekiti ekuchera

Mabhenefiti ekuchera akapfava kusvika epakati-akaoma dombo maumbirwo, kunyanya maumbirwo ematombo akaomarara, nekushandisa chibooreso chinosanganiswa ndeichi:

1. Kubudirira kwekupwanya kwedombo kunovandudzwa zvikuru

2. Kushanda kwepamusoro uye kupfupisa nguva yekuvaka

3. Kurudzira kuvandudzwa kwemidziyo yekuchera.

4. Kushandiswa kwepamusoro-soro PDC cutters inokurudzira kuchinja kwechimiro chedhaimondi bit uye kugadzirwa kwe hydraulic parameters.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
