I ka wā o ka nīnau nīnau a nā mea kūʻai aku, e haʻi mākou i ka mea kūʻai aku i ke kumukūʻai o hoʻokahi kilokani，ʻOi aku ka huikau o kekahi mau mea kūʻai aku, no ka mea, ʻaʻole lākou’'ike 'ole i ke kaumaha o ka pahu carbide sima poepoe, i maopopo ole ai ia lakou ke kumu kuai hookahi. ʻĀnō e haʻi ʻo zzbetter iā ʻoe i ke ʻano helu helu o ka pahu pōʻai carbide paʻa:

Hāʻawi ʻia: G=π×（Diameter/2）²×Ka lōʻihi×ʻO ka mānoanoa÷10⁶=    KG

Q: He aha ke kaumaha o ka YG10XΦ10mm*330mm poepoe bar?

 E helu pū kākou:

G=3.14×(10.4/2)2×330×14.5÷1000000=0.407KG

Nānā：Kūlike mākou i kaΦ10 blanks asΦ10.3-Φ10.4 (kaʻO ke koʻokoʻo carbide paʻa Φ10 a pono e lepo). Waiho mākou iā lākou331 i ka 333 lōʻihi. No laila e hoʻohana i ka ʻikepili i luna e lawe mai.)

ʻAʻole ʻike nui kekahi poʻe e pili ana i ka nui o nā māka carbide cemented, no lailaʻoi aku ka maikaʻi o zhuzhou tungsten carbide co.,ltdʻike ʻo ia ka helu ʻia ma lalo nei nā māka o nā kaola pōʻai carbide i hoʻohana mau ʻia.

Maopopo paha ia?

i haku i ke ano helu o ka pahu poepoe maluna, ke ano helu o kapaipu tungsten carbide ʻoi aku ka maʻalahi, I kēia manawa, ʻoi aku ka maikaʻi o ka haʻi ʻana iā ʻoe i ke ʻano helu helu o ka paipu poepoe carbide paʻa:

(Radius o ka pōʻai waho*radius o ka pōʻai o waho* 3.14*lōʻihi*density/10⁶= kaumaha o ka pōʻai waho)—(radius o ka pōʻai i loko* radius o ka pōʻai i loko * 3.14 * lōʻihi * density / 10⁶= ke kaumaha o ka pōʻai i loko) = ke kaumaha o ka paipu kalapona

O kahi laʻana

Q: He aha ke kaumaha o ka YG10XΦ10*Φ8*330 carbide paipu?

E helu pū kākou:

G=5.2*5.2*3.14*330.5*14.5/1000000—3.9*3.9*3.14*330.5*14.5/1000000=0.178kg

ʻO ka mea i luna nei ke ʻano helu helu o ka pahu pōʻai i ʻike pū ʻia e zzbetter me ʻoe i kēia lā, manaʻolana wau e pono ia! Ua aʻo anei ʻoe?
