Kina Slurry Pump Materials Selection hale hana a me nā mea hoʻolako | YAAO

I loko o kahi pump slurry ka impeller a i loko o ka casing e hōʻike mau ʻia i ka slurry a pono e pale ʻia e pili ana i ka lole.
"ʻO ke koho ʻana i nā mea no ka impeller a me ka casing ka mea nui e like me ke koho o ka pauma iā ia iho."

ʻEkolu mau kūlana ʻokoʻa e hana i ka lole i loko o ka pauma slurry:

Abrasion,'Āpana,Ka popopo

Abrasion

ʻEkolu ʻano nui o ka abrasion:
I nā pumps slurry loaʻa iā mākou ka nui o ka wili ʻana a me ka hoʻohaʻahaʻa haʻahaʻa.
Aia ka helu Abrasion i ka nui o ka huna a me ka paʻakikī.

Kū wale ka abrasion i nā wahi ʻelua i kahi pump slurry:
1. Ma waena o ka impeller a me ka puka komo paʻa.
2. Ma waena o ka ʻau lima a me ka hāʻawe paʻa.

Kaʻaʻai

ʻO kēia ka lole nui i nā pump slurry. ʻO ke kumu o ka paʻi ʻana o nā huna huna i ka ʻili ma nā ʻaoʻao like ʻole.
Hoʻomoʻa nui ʻia ka ʻaʻai ʻo erosion e ka hana ʻana o ka pauma. ʻO ka ʻaihū kahakai, ma ke ʻano nui, ma ka palena iki ma ka helu BEP fl ow, a hoʻonui me ka haʻahaʻa a me nā kahe kiʻekiʻe.
No nā kumu i hoʻomaopopo ʻole ʻia, hiki i ka ʻaʻai erosion ke hoʻonui nui hoʻi inā ʻae ʻia ka pauma e hana ma "snore"; ʻo ia hoʻi, ke lawe ʻana i ka ea i loko o ka paipu komo.
Kuhi ʻia e kumu ʻia kēia e ka cavitation, ma muli o nā ʻāpana o ka pauma e haʻalulu ana ma ke ʻano o ke ea ma luna o lākou. Eia nō naʻe, ʻokoʻa kēia e ʻae e like me nā huʻa ea e hoʻopau pinepine i ka cavitation ma ka neʻe ʻana e fll i nā lua o ka mahu.
ʻEkolu ʻano erosion nui:
Ka hopena o ka ʻaʻai ʻana ma nā ʻāpana pump:

Impeller

Hiki i ka impeller ke hoʻopili i ka hopena (kiʻekiʻe a haʻahaʻa) i ka maka, ma ka ʻaoʻao gland (A), ke huli ka 90 °. Ma ka lihi alakaʻi o ka vane (B).
Hiki ke moe i ka moena a me nā hopena angular haʻahaʻa ma nā wana ma waena o nā uhi impeller (C).
Nā lālani ʻaoʻao (nā puka komo a me nā laina hope)
Aia nā ʻaoʻao ʻaoʻao i ka moena e heʻe ana a me ka haki ʻana a me ka wili ʻana o ka abrasion.

Volute

Hiki i ka volute ke hopena i ka hopena o ka wai ʻoki. ʻO ka moena heʻe a me ka ʻaina hopena haʻahaʻa e komo ai i ke koena o ka volute.
Ka popopo:
ʻO ka hoʻohaunaele (a me nā hoʻouka kemika) o nā wahi pulu i kahi Slurry Pump kahi hanana paʻakikī no nā mea metala a me nā elastomer.
No ke alakaʻi ʻana, hāʻawi ʻia nā papa ʻaina kūmike no nā metala a me nā mea elastomer ma ka ukali ʻana a ma ka ʻāpana o nā Papa Kūlana Kemika

E pale i ka pale - he aha nā koho?

Aia kekahi mau koho nui i ke koho ʻana i ka pale o ka pale o nā pump slurry:
Impeller a me ka casing ma Hard Metal i nā ʻāpana like o ka hao keʻokeʻo a me ke kila.
Impeller i nā elastomers a me ka casing pale ʻia e nā laina elastomer. He kāpili maʻamau nā Elastomers i nā ʻano like ʻole a i ʻole polyurethane.
Hoʻohui ʻia o impeller o nā mea paʻa kila a me nā elastomer-lined casings.

Koho o nā mea ʻaʻahu

ʻo ke koho ʻana o nā ʻāpana ʻaʻahu ke kaulike ma waena o ke kūpaʻa ʻana i ka lole a me ke kumukūʻai o nā ʻāpana lole.
ʻElua mau papahana no ka pale ʻana i ka ʻaukā:
He mea paʻakikī ka mea ʻaʻahu e pale aku i ka hana ʻoki ʻana i nā paʻa paʻa! a i ʻole Pono e hoʻopaʻa i ka mea ʻaʻahu i hiki ke omo i nā haʻalulu a me ka rebound o nā mea ʻili!
