Kūʻai aku ʻo DTH hammers i nā ʻāpana wili pōhaku liʻiliʻi
Hōʻike huahana
Hana ʻia kahi ʻano nui o nā pihi pihi e kūpono i nā ʻano a me nā nui a pau o nā makamaka kaulana a pau o nā hāmare iho-ka-hole.
Loaʻa i nā ʻano poʻo like ʻole a me nā ʻano pihi, ua hoʻolālā ʻia lākou e hāʻawi i nā drillers i ka manawa e koho ai i ka bit maikaʻi loa no ka wili pono ʻana i nā ʻano pōhaku like ʻole a me nā kūlana honua.
Hana ʻia nā ʻāpana āpau i ke ʻano waena me ke kila nickel alloy kiʻekiʻe, ka mea i mālama ʻia i ka wela e hana i kahi ʻili e pale aku i ka luhi a me ka ʻaʻahu.
ʻO DTH (Down to Hole) drill bit, i kapa ʻia hoʻi ka spline connect drill bit, hoʻohana nui ʻia i loko o nā koʻu nui (wehe a ma lalo o ka lepo), ka ʻili ʻana a me ke kūkulu ʻana.Aia ka hāmare ma lalo o ka lua e pili pono ana me ka drill bit me nā splines ma ka bit.Paʻi ka piston hāmare i ka bit drill e hopena i ka hoʻoili maikaʻi ʻana o ka ikehu hopena a me nā poho mana liʻiliʻi me ka hohonu o ka lua.

Pehea e koho ai i ke ʻano o ka maka a me ke ʻano o ke pihi Carbide
A: Ke koho ʻana i ke ʻano o ke alo
Hoʻokuʻu i waena Bit
No ka piʻi kiʻekiʻe o ke komo ʻana ma nā ʻano pōhaku palupalu a paʻakikī a māwae.
Maka Poʻo
ʻO ke alo o ka palapala noi holoʻokoʻa no ke kūkulu ʻia ʻana o ka pōhaku ʻano paʻakikī a homogeneous.ʻO ka mana hole deviation maikaʻi a me ka mana flushing maikaʻi.
Maka Huhu
No ka piʻi kiʻekiʻe o ke komo ʻana ma ka palupalu a me ka paʻakikī me ka haʻahaʻa a me ke kaomi ea.ʻO ia ke kū'ē loa i ka holoi kila, a me ke kū'ē maikaʻi i ke kila holoi wāwae ana.
Bit Maka Paha
He kūpono kēia ʻano ʻano maka no nā ʻano pōhaku paʻakikī a paʻakikī loa i nā noi me nā ea kiʻekiʻe.ʻO ke komo ʻana maikaʻi ke kūʻē i ka holoi kila.
B: E hoʻokomo i ke ʻano o ka pihi Carbide
He kūpono ke pihi ʻokoʻa no nā kūlana honua like ʻole, nā pae abrasive, PSI a me nā pae komo.Ma keʻano laulā, ʻoi aku ka nui o nā pihi gauge, ʻoi aku ka maikaʻi ma mua o ka hana, ʻoi aku ka paʻakikī.
pōʻai
- Noi ka ikaika-nui
- ʻOi aku ka maikaʻi i ka abrasive palupalu
- 25,000 a 45,000 PSI (170 a 300 MPa)
- Abrasive a hiki loa
Pākuʻi Ballistic
- Ka ikaika o ka noi - komo wikiwiki
- Ua kūpono i ka lepo palupalu
- 10,000 a 20,000 PSI(70 a 140 MPa)
- ʻAʻohe abrasive lepo
Semi-ballistic
- Noi Ka ikaika-ke komo wikiwiki
- Ua kūpono i ka ʻāina waena
- 15,000 a 25,000 PSI(100 a 170 MP)
- ʻAha ʻāwīwī
Pākuʻi (Conical).
- Ka ikaika o ka noi - komo wikiwiki
- He kūpono no nā ʻano ʻāina āpau ʻole abrasive
- Wahi pili liʻiliʻi
- He kūpono no nā ʻāpana liʻiliʻi liʻiliʻi
ʻO nā hiʻohiʻona o nā ʻāpana kila Nickel-alloy
1) Pono
Hoʻohana ka piston o DTH Hammer i ke kila kila nickel kiʻekiʻe (i lawe ʻia mai), me ka hoʻomaʻamaʻa wela kiʻekiʻe e like me ke kūlana ʻoihana koa.
ʻO ka hoʻoikaika ʻana i ka hana ʻana ma ka ʻili hāmare no ke kūpaʻa kiʻekiʻe.
2) Pono
Nā ʻāpana drill i hoʻolālā kūikawā ʻia no ka hoʻokumu ʻana i nā pōhaku palupalu a paʻakikī.E wehe maʻalahi i ke kaula no ka mālama maʻalahi.
3) Pono
Hoʻolālā ʻokoʻa pōkole DTH hāmare a me ka bit no ka maikaʻi o ka hoʻoili ʻana i ka ikehu hopena kiʻekiʻe, me ka mana hopena kiʻekiʻe a me ka wikiwiki wili ʻana.
Hoʻolālā ʻia ka hammer a me ka bit e ka hoʻohālikelike kamepiula, me ke keʻena hoʻolaha ea maikaʻi loa a me ka hoʻolālā paʻa ʻana o ka ea.
