ʻO ka ʻāpana koʻikoʻi o nā ʻāpana wili karbida hou - nā nozzle carbide

ʻO ka nozzle ka mea nui o ka bit drill carbide hou, a ʻo kāna hana e hoʻoholo pololei i ka pono o ka haʻihaʻi pōhaku o ka bit drill. Ma muli o ka hoʻokomo ʻia ʻana o ka nozzle i loko o ka bit drill carbide cemented hou a ua kaupalena ʻia kona lōʻihi a me ke anawaena o waho, ua kūpono nā kūlana hoʻolālā nozzle ʻoihana i kēia manawa no nā kūlana ʻaʻole i kaupalena ʻia, no laila pono e hoʻolālā ʻia ka nozzle e hana i ka hopena punching maikaʻi loa. ka mokulele. Ma lalo o ka ʻenehana loea kūikawā o ka nui o ka nozzle palena, pono ka hoʻolālā nozzle e hoʻokō i nā koi aʻe:

① ʻOi aku ka nui o ka hopena o ka jet e koi ʻia, ʻoi aku ka maikaʻi, i hiki ai i ka pōhaku paʻa ke haki. I ka manawa like, koi ʻia ʻo ke kahawai jet e like me ka hiki, i hiki ke pale pono i ka hoʻopili ʻana o ka drill bit alakaʻi ma ke kahawai jet. ʻO ka nui o ka jet, ʻo ia hoʻi, ma hope o ka haʻalele ʻana o ka jet i ka nozzle, ʻoi aku ka maikaʻi o ka convergence a ʻoi aku ka liʻiliʻi o ke kihi diffusion o ka jet. Akā i ka manawa like, koi ʻia ka nui o ka aperture o ka jet erosion, i hiki ke wāwahi mua ʻia ka pōhaku no ka bit alakaʻi, a hiki ke hoʻemi ʻia ka ikaika o ka mea hana i ka nui.

ʻO ke ʻano kumu o ka jet ma hope o ka haʻalele ʻana i ka nozzle: ʻo ia ka hapa nui o ka ʻāpana mua a me ka ʻāpana kumu, a aia kahi ʻāpana hoʻopau ma hope o ka ʻāpana kumu, akā ua haki ka jet i kēia ʻāpana i nā kulu wai. Aia kahi conical iso-kinetic flow core region ma ka ʻāpana mua, e mālama mau ana i ka wikiwiki injection mua. Loaʻa i kēlā me kēia ʻāpana nā hana like ʻole i nā noi ʻenekinia pono, kūpono ka ʻāpana mua no ka ʻoki ʻana a me ka ʻoki ʻana, kūpono ka ʻāpana kumu no ka hoʻoponopono ʻana i ka ʻili, ka hoʻomaʻemaʻe ʻana, ka wehe ʻana i ka ʻōpala, a me nā mea ʻē aʻe. . Ma kēia haʻawina, hoʻohana nui ʻia ka ʻāpana kumu o ka jet e wāwahi i nā pōhaku. No laila, pono e hana ka hoʻolālā nozzle i ka ʻāpana koʻikoʻi o ka jet i ka lōʻihi e hiki ai, hiki ke hoʻoikaika i ka jet i ka ikaika erosion ma kahi lōʻihi. ʻO ka lōʻihi iso-velocity core e hiki ai i ka abrasive ke hoʻomau i ka wikiwiki ma hope o ka haʻalele ʻana i ka nozzle, pēlā e hoʻomaikaʻi ai i ka wikiwiki o nā ʻāpana abrasive. ʻO ka nui o ka nui o ka jet e pili ana i ke kihi ʻokiʻoki o ka nozzle, a pono ke koho ʻia ka ʻokiʻoki nozzle kūpono i ka hoʻolālā ʻana o ka nozzle.

②E hōʻoia i ke ola o ka nozzle hiki ke hoʻokō i nā koi ʻenehana. Ma o ka hoʻolālā hoʻolālā kūpono a me ke koho ʻana i nā mea, hoʻohālikelike ʻia ke ola lawelawe o ka nozzle me ke ola o ka drill, a ma ka manawa like, noʻonoʻo ʻia ka hoʻokele waiwai, a koho ʻia nā mea i kūpono i nā koi ma muli o nā kumukūʻai kūpono.

② ʻO ka nozzle he wai paʻa ʻelua-phase kahe kiʻekiʻe kiʻekiʻe, ʻaʻahu wikiwiki ka nozzle, no laila ʻoi aku ka kiʻekiʻe o nā mea o ka nozzle, pono e loaʻa i ka nozzle ka ikaika mechanical a me ke kūpaʻa maikaʻi a me ka pale ʻana i ka corrosion. I kēia manawa, hoʻohana pinepine ʻia ka tungsten carbide, daimana, a me nā mea waiwai. ʻO ka paʻakikī o ka nozzle carbide cemented hiki ke hōʻea i ka HRC93, hiki i ka ikaika compressive ke hiki i 6000MPa, a he ikaika kona pale ʻana. Hana ʻia nā nozzles Tungsten carbide e ke ʻano metallurgy pauka, a hoʻoheheʻe ʻia nā nozzles e ka make kila.

③ He kiʻekiʻe loa ka paʻakikī o ka daimana, ʻo ka paʻakikī o Mohs o 10, a me ka hiki ke hōʻino i ka anti-cavitation, ʻoi aku ka lōʻihi o ke ola ma mua o ka tungsten carbide, akā ma muli o ke ʻano paʻakikī, haʻahaʻa ka polishing pololei, ua like ka maikaʻi o ka jet me ka tungsten carbide nozzle. , ʻoi aku ka maikaʻi o ke kumukūʻai, e noʻonoʻo ana i ka hoʻokele waiwai hiki ke haʻalele i kēia mea. Nui nā ʻano pōhaku ʻano, e like me ka sapeira, ka rubi, a pēlā aku. ʻO ka paʻakikī kiʻekiʻe, a me ke kūpaʻa ikaika i ka abrasion jet wai, akā he mea brittle, maʻalahi e wāwahi. Hoʻohui i ka maikaʻi o nā jet nozzles, ka paʻakikī o ka hoʻoili ʻana, ke kumukūʻai, a me ke kumukūʻai, hoʻohana kā mākou hui i nā mea tungsten carbide e hana i nā nozzles.

Hana ʻo ZZBETTER i nā ʻano nozzles carbide, hiki ke hoʻokō i nā koi o kā mākou mea kūʻai mai nā ʻoihana like ʻole a me nā māla. Hiki iā mākou ke hana i nā mea maʻamau ʻole a me nā huahana tungsten carbide ʻē aʻe. Welina mai e kipa i kā mākou pūnaewele inā makemake ʻoe: www.zzbetter.com.
