Nā Nozzles Water Jet Tungsten Carbide
He aha ka tungsten carbide i koho maikaʻi loa no nā nozzles?
• ʻO Super coarse grain hard alloy virgin raw material, 100% alloy ma ke kaomi ʻana a me ka sintering, i hoʻonui ʻia ka paʻakikī a me ka paʻakikī o ka drill bit e 30% i ka manawa like.
• Hoʻolālā kūʻokoʻa, hoʻonui ka wikiwiki o ka ʻeli ʻana a me ka ʻeli ʻana i 20%, hoʻonui ke ola i 30%
• Ke kūpaʻa ʻana o ka nui ma nā wahi me nā kūlana kiʻekiʻe o ka wela a me ke kaomi
• He hoʻopau maikaʻi e maʻalahi ke hoʻomaʻemaʻe
• Kūleʻa maikaʻi loa, kū'ē i ka abrasion
Maikaʻi ke kumu kūʻai ma muli o ke ola lōʻihi a me nā pono mālama pono ʻole.
ʻO ke kumu nui loa
(1) ma lalo o kekahi mau kūlana, e like me ka nozzle diameter, injection Angle a me ka mamao spray, ʻoi aku ka kiʻekiʻe o ke kaomi jet, ʻoi aku ka maikaʻi o ka hopena haʻihaʻi pōhaku;
(2) ma lalo o ke kūlana nozzle anawaena, injection Angle a me ka nozzle neʻe wikiwiki e mau, e hoʻonui ka mamao spray maikaʻi me ka piʻi ʻana o ke kaomi, hiki i 32.5 manawa o ka nozzle anawaena ma 200MPa;
(3) ʻo ke kumu o ka neʻe ʻana o ka nozzle e hōʻike i ka manawa hana o ka pōhaku erosion jet.Ke emi ma lalo o 2.9mm/s, liʻiliʻi kona hopena i ka hopena erosion o ka pōhaku.
(4) ke emi ka puʻe ma mua o 150MPa, piʻi ka jet pressure a piʻi wikiwiki ka nui o ka haʻihaʻi pōhaku i kēlā me kēia mana;akā naʻe, ke piʻi aʻe ka puʻe, e emi iki ka leo haʻihaʻi pōhaku no kēlā me kēia mana, a ʻo ka maikaʻi haʻihaʻi pōhaku ka mea kiʻekiʻe loa ma 150MPa.
(5) neʻe ka nozzle kiʻekiʻe kiʻekiʻe i mua, me ka hopena haʻihaʻi pōhaku maikaʻi loa a me ka Angle injection maikaʻi loa o 12.50.
