Slurry volume loss runtime Slurry i ka hana ʻana, ʻaʻole like ke kaomi wai o ka paila ma ke kino, he wahi kaomi kiʻekiʻe, aia nā wahi haʻahaʻa. No ka mea e pono ai ke kūkulu ʻana, nui nā āpau i loko o ke kino pāpaʻi, i ka wā e kahe ana ka ʻāpana a puni ka pae paʻi, e kahe ka wai mai ke kiʻekiʻe kiʻekiʻe a hiki i ka haʻahaʻa haʻahaʻa, ʻo kēia ʻāpana o ka ʻāpana kiʻekiʻe o ka wai hoʻi i loko. ka haʻahaʻa puʻe māhele 'āina, oiai e kahe ana i loko o ka ikehu functional loaa i ka impeller, akā,ʻaʻole i ka pono hoʻohana, akā, i ke kaapuni o ke kino pauma, no ka mea, o ke āpau e lanakila ai i ke kū'ē a me ka pau, ua kapaia keia poho poho.
E like me ka wai mai loko mai o ka hapa o ka impeller i loko o ka pauma hope,ʻaʻole i hoʻokuʻuʻia mai loko mai o ka pauma, ka pauma hoʻokuʻu kahe ana Q o ka maoli lākiō o ka kahe ana ma o ka impeller Q 'e liʻiliʻi.
Hoʻokaʻawale leo poho
(1) kahi o ka puka komo o ka impeller, ka impeller a me ke kino pump he wahi liʻiliʻi liʻiliʻi. ʻO ke kaomi i loko o ka lua o ka impeller impeller inlet ma mua o ke kiʻekiʻe, no laila aia kahi āpau liʻiliʻi mai ka wai waihona ma o ka sila hoʻi i loko o ka impeller inlet impeller puka. Hoʻohana maikaʻi ʻia kēia ʻāpana o ka wai ma ke ʻano he impeller o kahi koho kūleʻa, a ʻo ka poho ke lanakila ʻana i ke kūʻē ʻana o ka ʻāpana sila. ʻO ka mea maʻamau, ua kapa ʻia kēia ʻāpana o ka nalowale o ka ikehu he seal ring leakage losses. Kahe ka wai i loaʻa ma o ka mechanics o ke kumu e helu ai i ka nui o ka leakage ma ke apo sealing q1 (m ^ 3 / s): nā wai maloʻo a i ʻole nā wai me nā mea paʻa me ka pauma palaoa, ʻoi aku ka nui o ke apo o ka sila ma mua o ka waiwai ma ka Papa 2 -1 iki . Hiki ke hoʻoholo ʻia ka lōʻihi o ke apo apo hoʻopaʻa l e like me ke ʻano kikoʻī.
(2) Ma ke kaulike centrifugal axial force maʻamau i loko o nā keʻena ʻelua, e like me ka lua kaulike (Figure 2-11) a me ka pā kaulike a pēlā aku. ʻOiai ʻo kahi hapa o ka wai i loaʻa mai ka impeller o ka ikehu, akā ʻaʻole i hoʻohana pono ʻia a hoʻopau ʻia e lanakila ai i ke kūʻē ʻana ma ke ʻano kaulike, ʻo ia hoʻi ka nui o ka nalowale o ka ikehu. Ma ka hoʻokomo ʻana i ka helu ʻana o ka nui o ka leak wai e kūkākūkā ʻia ma ka Mokuna VII. Ma ka nui o ka leakage ma ka lua koena hiki ke hoʻohālikelike ʻia e ke ʻano (2-13), ʻo ka hele ʻana o ka puʻu koena ʻoi aku ka maikaʻi o 3-6%.
Eia kekahi, ʻo ka pauma multi-stage, ma kahi o nā ʻāpana ʻelua ma luna o ka leakage leakage volume loss, ʻaʻohe ʻāpana o ka leakage leakage leakage. ʻO nā pāpaʻi multi-stage maʻamau ka pae ʻāpana ʻāpana, no ka mea, ʻokoʻa ke kiʻekiʻe o ka wai ma hope o ka pā kaomi ʻana,mea hana pahū slurryno laila, he hapa o ka wai ma ka pae hoʻi i loko o ka pā pā ma waena o ka ʻaoʻao impeller o ka hoʻomaʻemaʻe mua, ka leakage āpau ma waena o ka pae wai, ma waena o ka impeller a me ke alakaʻi ʻana i ka vane backlash ma hope o ka hui ʻana me ka wai mai ka impeller, ka alakai vanes a me ka ABM lau, akā, ma ka pae pae ma waena o ka impeller hoʻi i loko o ka pre-backlash, a pela aku. No ka mea ʻaʻole e hele kēia ʻāpana o ka wai i ka impeller, ʻaʻole pili i ka kahe o ka paila, no laila ʻaʻole lilo kēia ʻāpana o ka ikehu.
