PDC drill bits nozzles
Kenyelletso ea Tlhahiso
Nozzle e entsoeng ka samente ea carbide ke e 'ngoe ea likarolo tsa bohlokoa bakeng sa drill ea daemane, tungsten carbide drill bit nozzle e sebetsa ho flush, pholile, le ho tlotsa malebela a likotoana tsa ho cheka, li-nozzles tsa carbide le tsona li ka hloekisa litsupa tsa majoe ka tlase ho seliba ka ho cheka. mokelikeli maemong a ts'ebetso a khatello e phahameng, ho thothomela, lehlabathe, le seretse se nang le tšusumetso nakong ea ho batla oli le khase ea tlhaho.Li-nozzles tsa Carbide le tsona li na le phello ea hydraulic rock fragmentation.Nozzle e tloaelehileng ke cylindrical;e ka hlahisa kabo e leka-lekaneng ea khatello holim'a lefika.
Li-nozzles tsa tungsten carbide li sebelisoa haholo-holo bakeng sa li-cutter tse tsitsitseng le li-cone roller bits bakeng sa metsi a pholileng le ho hlatsoa seretse, ho latela ho cheka ha tikoloho ea sebaka, re tla khetha phallo e fapaneng ea metsi le boholo ba masoba ka sebōpeho sa li-nozzles tsa tungsten.
Mefuta ea li-nozzles tsa carbide
Ho na le mefuta e 'meli ea mantlha ea li-nozzles tsa carbide bakeng sa likotoana tsa ho cheka.E 'ngoe e na le khoele, 'me e 'ngoe ha e na khoele.Li-nozzles tsa carbide tse se nang khoele li sebelisoa haholo-holo holim'a li-roller bit, li-nozzles tsa carbide tse nang le khoele li sebelisoa haholo ho drill bitana ea PDC.Ho ea ka lisebelisoa tse fapaneng tsa ho sebetsana le lisebelisoa, ho na le mefuta e 6 ea li-nozzles tse lohiloeng bakeng sa likotoana tsa PDC:
1. Cross groove thread nozzles
2. Li-nozzles tsa mofuta oa Plum blossom
3. Li-nozzles tsa ka ntle tsa hexagonal
4. Li-nozzles tse ka hare tsa hexagonal
5. Mofuta oa Y (3 slot / grooves) likhoele tsa likhoele
6. Gear drill bit nozzles le tobetsa fracturing nozzles.
Kedel Tool e ka hlahisa mefuta e mengata ea likhoele tsa nozzle bakeng sa likotoana tsa ho cheka tsa PDC ka har'a metric le khoele ea borena.Khoele e kopaneng ea naha e mahoashe, khoele e ntle, le likhoele tse khethehileng ho kenyeletsoa ho nepahala ha sehlopha sa 3, ho nepahala ho holimo ho maemo a Amerika.Ho ea ka litlhoko tsa hau tsa carbide bit, li ka etsoa ka ho fapanyetsana.
Ha re khone feela ho hlahisa li-nozzles tse tloaelehileng tsa tungsten carbide, empa hape re khona ho hlahisa li-nozzles tse ikhethileng ho latela litšoantšo kapa lisampole.Li-nozzles li fumaneha ka mefuta e mengata e fapaneng ea mefuta le mefuta e fapaneng ea boholo bakeng sa lisebelisoa tse ngata tsa ho cheka ka mekoti.Limaraka tsa rona tse lekiloeng tšimong li etselitsoe ho tiea ho hoholo le ho hanyetsa ho roala lits'ebetsong tsa matla a torque e phahameng.Re ka kopanya sehlopha se khethehileng sa tungsten carbide bakeng sa hau.Re na le boiphihlelo ba ho hlahisa libopeho le boholo bo fapaneng ba li-nozzle tsa tungsten alloy.
