1 mea: mea slurry pump impeller a me volute, e like me nā mea elastic e like me ka rubber, neoprene, polyurethane resin, maʻamau i hoʻohana ʻia i ka manawa o ka wikiwiki o ka impeller puka haʻahaʻa ma mua o 23 m / s, hiki ke hoʻomaikaʻi maikaʻi i ka pump NPSH.
2 mau ʻāpana paʻa i ka mana o ka pauma centrifugal, ke kahe o ka pauma slurry - ʻoi aku ka palahalaha o ka piʻi ʻana, a e piʻi aʻe ke kahe o ka pipeline me ka piʻi ʻana o ke kaʻa a me ka lohi, pipeline hiʻohiʻona curve a me ka pihi hana He liʻiliʻi ke kihi, ka ʻO ke poʻo o kahi hoʻololi liʻiliʻi hiki ke hoʻololi nui i ke kahe.
3 mechanical design, shaft, bearing, seal, pump body, etc.): pono ke kiʻekiʻe o ka ikaika a me ka paʻa a me ka hilinaʻi o ka lāʻau a me ka halihali. Hiki i ka impeller hoʻopili ʻo Trapezoidal ke kū i ka haʻawe kaumaha, ma lalo o ke kūlana o ka haʻawe kaumaha me ka hoʻohana ʻana i ka sliding thrust bearing a hoʻohana pinepine ʻia ka hali pōpō i nā kūlana haʻahaʻa māmā.
4 ʻaʻahu a me ka hana hydraulic o ka pilikia: i mea e hōʻemi ai i ka ʻaʻahu a me ka waimaka, pono e hoʻomau i nā ʻāpana ʻōwili a haʻahaʻa ka wikiwiki o ka wai, pono e hoʻonui ʻia ka mānoanoa o ka ʻāpana kino e hoʻokō ai i nā pono. o ka hana pono. ʻO ka ʻaoʻao radial o ka impeller, kokoke i ka rectangle, a ʻoi aku ka liʻiliʻi ma ka mokulele kū i ka hoʻohana ʻana i ka ʻāpana rotation axial seal mua, ka hoʻolālā maʻamau o ka pahu pahu no ka hapalua spiral, a i ʻole ka pōʻai, i hana ʻia ma ka hana kiʻekiʻe loa kokoke i ka lae o ākea o ka liʻiliʻi o ka lole a me ka waimaka. I ka wā e pono ai nā ʻāpana nui o ka lawe ʻana i ka paʻa, ʻoi aku ka nui, ʻo ka laulā o ka helu impeller blade i hoʻopaʻa ʻia i hoʻemi ʻia i 2-3 mau ʻāpana, ma ke kumu o ka hoʻomaikaʻi ʻana i ka ʻaʻahu o ka pā, ʻo ka hana hydraulic pump he ʻokoʻa ke ʻano o ka emi ʻana. .
Slurry pump vice impeller shaft seal packing sila, sila, sila mechanical.
1, ʻo ka slurry pump packing seal e hilinaʻi ʻia ma ke ʻano o ka hopena sealing paʻakikī a palupalu ma waena o ka hoʻopili ʻana a me ka lima lima, ʻo ka hoʻopaʻa ʻana i ka sila a me ka shaft seal water shaft seal water pressure e pono e ʻoi aku ka nui o ka slurry pump outlet pressure o 1.5 kg, ke ʻano o ka sila hoʻohana nui ʻia. ma ka hale lole, holoi lanahu.
2, slurry pump mechanical seal mechanical seal, friction play a sealing effect of dynamic and static ring close points i māhele ʻia i mechanical seal ma waho me ka ʻole o ka wai injection type mechanical seal, holoi ke ʻano wai i loko o ka mechanical seal, ka wai injection type mechanical seal . ʻAʻole pono ke hoʻohui i ka wai hoʻoheheʻe wai ʻano mechanical seal, ke ola lawelawe ma kahi o 4000 mau hola; Ma waho o ka flushing water injection type mechanical seal and shaft seal water shaft seal water pressure o 1.5 kg, ke ola lawelawe ma kahi o 6000 hola; ʻO ke ʻano wai hoʻoheheʻe wai e holoi ai i ka sila mechanical me ka wai seal shaft e koi ʻia, ʻoi aku ka nui o ka wai ma mua o ka slurry pump outlet pressure o 1.5 kg, ke ola lawelawe ma kahi o 8000 mau hola.
3, vice impeller o slurry pauma sila ua hanaia e vice impeller puʻe seal hopena, i ke koi o ka slurry pump kahe hope puʻe i ole e oi aku mamua o 15% slurry pauma puka kaomi, i ka mea hoʻohana o ka wai shortage i keia sila.
