PDC kubowola ma nozzles

PDC kubowola ma nozzles, omwe amakhala ndi mawonekedwe osavuta, mphamvu yayikulu, kukana kwamphamvu kwambiri, komanso kukana kwambiri, ndi mawonekedwe a PDC bit nozzle ndi imodzi mwamaukadaulo atatu atsopano obowola padziko lapansi m'ma 1980. Kugwiritsa ntchito kumunda kukuwonetsa kuti kubowola kwa diamondi ndikoyenera kupanga zofewa kapena zolimba zapakati chifukwa cha zabwino za moyo wautali wautumiki, kutsika pang'ono, komanso kubowola kosasinthasintha.

Mau oyamba a Zopanga

Simenti ya carbide nozzle ndi imodzi mwazinthu zofunika kwambiri pakubowola kwa diamondi, tungsten carbide kubowola pang'ono nozzle imagwira ntchito kuti isungunuke, kuziziritsa, komanso kuthira mafuta nsonga zobowola, ma nozzles a carbide amathanso kuyeretsa tchipisi ta miyala pansi pa chitsime ndikubowola madzi m'malo ogwirira ntchito mwamphamvu, kugwedezeka, mchenga, ndi kuyang'ana kwachilengedwe kwamafuta. Carbide nozzles amakhalanso ndi hydraulic rock fragmentation effect. The nozzle ochiritsira ndi cylindrical; imatha kupanga kugawa kwapakati pamwala.

Mitsuko ya tungsten carbide imagwiritsidwa ntchito makamaka ngati tinthu tating'onoting'ono todulira ndi ma cone roller bits poziziritsa madzi ndi kutsuka matope, malinga ndi kubowola kwa chilengedwe, tidzasankha madzi osiyanasiyana komanso kukula kwa dzenje mu mawonekedwe a nozzles za tungsten.

Mitundu ya nozzles ya carbide

Pali mitundu iwiri ikuluikulu ya ma nozzles a carbide pazobowola. Wina ali ndi ulusi, ndipo wina ali wopanda ulusi. Ma nozzles a carbide opanda ulusi amagwiritsidwa ntchito makamaka pa chodzigudubuza, milomo ya carbide yokhala ndi ulusi imagwiritsidwa ntchito makamaka pa kubowola kwa PDC. Malinga ndi zida zosiyanasiyana zogwirira ntchito, pali mitundu 6 ya ma nozzles opangidwa ndi ma PDC bits:

1. Mabomba a ulusi wodutsa poyambira

2. Maula amtundu wa maluwa a ulusi

3. Zingwe zakunja za hexagonal

4. Internal hexagonal ulusi nozzles

5. Y mtundu (3 kagawo / grooves) ulusi nozzles

6. zida gudumu kubowola pang'ono nozzles ndi atolankhani fracturing nozzles.

Kedel Tool imatha kupanga mitundu yambiri ya ulusi wa nozzle wa PDC kubowola bits mu metric ndi ulusi wachifumu. Ulusi wolumikizana wamitundu yonse, ulusi wabwino, ndi ulusi wapadera kuphatikiza giredi 3 yolondola, yolondola kwambiri mulingo waku America. Malinga ndi zomwe mukufuna pa carbide bit, zitha kupangidwa ndikusinthana.

Sitingangopanga ma tungsten carbide nozzles, komanso timatha kupanga ma nozzles makonda malinga ndi zojambula kapena zitsanzo. Ma Nozzles amapezeka mumitundu yosiyanasiyana komanso kukula kwake pamabowo ambiri obowola pansi. Magiredi athu oyesedwa m'munda adapangidwa kuti akhale olimba kwambiri komanso kuti asavale pamapulogalamu amphamvu kwambiri. Titha kuphatikizira kalasi yapadera ya tungsten carbide kwa inu. Tili ndi luso lopanga mawonekedwe ndi makulidwe osiyanasiyana a tungsten alloy nozzles.
