PDC kubowola ma nozzles
Mau oyamba a Zopanga
Mphuno ya simenti ya carbide ndi imodzi mwazinthu zofunika pakubowola kwa diamondi, tungsten carbide drill bit nozzle imagwira ntchito pakuwotcha, kuziziritsa, komanso kudzoza nsonga zabowolo, ma carbide amathanso kuyeretsa tchipisi ta miyala pansi pa chitsime ndikubowola. zamadzimadzi pakugwira ntchito kwamphamvu kwambiri, kugwedezeka, mchenga, ndi slurry zomwe zimakhudzidwa panthawi yofufuza mafuta ndi gasi.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. Mipukutu ya 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 kukana kuvala pamapulogalamu amphamvu kwambiri.Titha kuphatikizira kalasi yapadera ya tungsten carbide kwa inu.Tili ndi luso lopanga mawonekedwe ndi makulidwe osiyanasiyana a tungsten alloy nozzles.
