pale i ka nalowale o ka slurry pump

Volume poho a e pale aku i ka nalowale o ka slurry pump

Volume poho centrifugal china slurry pump seal apo leakage poho, poho o ke kaulike ma waena o nā keʻena a me ka pae o ka leakage poho.

He poho leakage apo sila

I loko o ka impeller inlet, he apo hoʻopaʻa i loko o ka china slurry pump hana, no ka mea, ʻo nā apo sealing ma nā ʻaoʻao ʻelua he ʻokoʻa puʻupuʻu, ʻo ka ʻaoʻao o ke kaomi puka impeller ma kahi o hoʻokahi ʻaoʻao o ke kaomi inlet impeller, no laila e mau mau ana. he ʻāpana o ka wai mai ka puka impeller a i ka impeller inlet leakage . ʻO kēia ʻāpana o ka wai i loaʻa i ka ikehu o ka impeller, akā ʻaʻole i hoʻouna ʻia ka wai, pēlā e hōʻemi ai i ka nui o ka wai china slurry pump. ʻO ka ikehu a pau i hoʻohana ʻia e lanakila ai i ka leakage o ke apo seal wai ma ke kūʻē.
ʻIke loa, ʻoi aku ka nui o ke apo seal anawaena Dw, ʻoi aku ka ʻilihune ma nā ʻaoʻao ʻelua o ka ʻokoʻa kaomi, ʻoi aku ka nui o ka leakage. No ka stereotypes china slurry pumps, i mea e emi ai ka nui o ka leakage e hoʻomaikaʻi i ka pono o ka china slurry pump pono e ʻae ʻia i ka hihia o ke apo sealing gap narrowing. ʻO ka mea maʻamau e pili ana i ka nui o ka hoʻomaʻemaʻe ʻana i ke apo apo apo 0.002, e like me Dw = 200 mm, ʻo ka huina hoʻomaʻemaʻe o 0.40 mm. I ka hui ʻana, ʻaʻole nui loa ke apo seal, i ʻole, e hoʻonui ka nui o ka leakage. ʻO kekahi kī nui i hoʻohana ʻia no ka hoʻonui ʻana i ke kūʻē ʻana o ke apo seal ala no ka hōʻemi ʻana i ka nui o ka leakage, hoʻonui i ke kūʻē ʻana o ke apo seal i hana ʻia i ka maze , zigzag, etc. hoʻonui i ke kū'ē ma ke ala .
Leakage o ke apo sila, a ma kekahi mau hihia e hiki ke hoʻopilikia i ka impeller inlet, no laila, pono e hoʻolālā i ke apo sila.

ʻO ka lua, nā poho leakage o ka mīkini kaulike

I loko o ka nui o ka centrifugal china slurry pump, axial thrust balancing hiʻohiʻona hui: e like me ke kaulike ʻana i nā lua, ka mālama ʻana i ke kaulike, ka disc balance. No ka mea he ʻelua ʻaoʻao e kaulike i ka mīkini ʻokoʻa puʻe, a no laila he ʻāpana o ka leaka wai mai ka ʻāpana kiʻekiʻe a hiki i ka ʻāpana haʻahaʻa haʻahaʻa. Ma kahi o 5% e hōʻemi i ka lua leakage e kaulike i ka pono o ka slurry pump china. I loko o nā keʻena diski kaulike, ʻoi aku ka leakage no 3% o ke kahe o ka hana, akā ʻoi aku ka nui o kekahi o ka slurry pump china kiʻekiʻe ma mua o kēia; i mea e hoemi leakage poho hiki ke hoemi i ke kaulike disc anawaena D me ka pili ole i ke kulana counterweight '.

ʻO ke kolu, nā poho leakage interstage

I loko o ka multi-stage volute china slurry pump, ka pae o ka spacing ma nā ʻaoʻao ʻelua o nā pae pā kaomi, no laila e loaʻa nā leakage, e like me ka hoʻonohonoho ʻana o nā keʻena like ʻole, ʻo ke kiʻekiʻe o ke kaomi ma nā ʻaoʻao ʻelua o nā papa spacer ke kumu mua. lua a i ʻole ke kula kiʻekiʻe, ʻoi aku ka ʻokoʻa o nā pae, a laila ʻoi aku ka nui o ka leakage ma waena o ka pae ʻāpana, no laila ua hoʻohana nui ʻia ma waena o ka sila pae wāwae.

Eia kekahi, i ka mahele slurry pump multi-stage china, aia nā leakage inter-stage. Akā ʻokoʻa kēia leakage ma waena o ka pae i ʻōlelo ʻia ma mua, no ka mea ʻaʻole leak kēia ʻāpana o ka wai ma o ka impeller, ʻaʻole ia i ka pohō leo. Maʻaneʻi, ke kiʻekiʻe o ke kaomi a puni ka pā ʻāpana, kaomi ʻia e ka hopena diffusion o nā vanes o ka ʻaoʻao impeller a me ka ʻāpana suction (e like me ka impeller centrifugal). Ma ke ʻano o ke kaomi ʻokoʻa, ka leakage o nā manawa pae wai ma ka papa ma mua o ke komo ʻana i ka impeller gap backlash, a ma nā ʻaoʻao alakaʻi, lau ABM (inhalation guide vanes) a hoʻi i loko o ke āpau ma waena o ka pae, e hana hou i ke kaʻina hana. ʻOiai ʻaʻole pili ka leakage slurry pump ma waena o nā ʻāpana multi-stage slurry pump leakage level, akā ua puni ka holo ʻana i ka hoʻohana mana slurry pump china. Eia kekahi, ʻo ka ʻāpana o ka wai ma o nā ʻaoʻao alakaʻi, vane throat e hoʻemi i ka pauku keʻa maikaʻi (ʻo ia hoʻi, lawe ka leakage o ka wai i kahi ʻāpana o ke keʻa), e hoʻonui ia i ka kahe kahe ma ʻaneʻi, e hoʻonui ai i nā poho hydraulic. . Wahi a ka "centrifugal china slurry pump design basis," he puke e pili ana i: he multi-stage china slurry pump, ma ke kahe kahe o 20 l / s, ke āpau ma waena o ka pae i emi mai ka 0.75 mm a 0.25 mm, ka nui leakage interstage q emi o 0.7 lita / sec. ma muli o ka emi ʻana o q, ua hoʻemi ʻia ke kahe e hele ana i loko o nā vanes, e hōʻemi ana i ka kahe kahe o ka ʻāʻī vane, e hōʻemi ana i ka nalowale o ka wai i loko o nā vanes, a no ka hōʻemi ʻana o q i ka wikiwiki pili o ka impeller e haʻalele ka wai i ka slot alakaʻi i loko. ka ʻaoʻao i hōʻemi ʻia, pēlā e hōʻemi ai i ka nalowale o ka friction o ka disc impeller, no laila ua hoʻomaikaʻi ʻia ka maikaʻi o ka slurry pump china ma kahi o 5%.
