ʻAʻole kala ʻia nā wahi ʻoihana paʻakikī. I loko o nā mea kanu hoʻoponopono kemika, nā ʻāpana desulfurization o ke kinoea, a i ʻole nā mea hoʻomaʻemaʻe kahakai, hāʻule nā pepa hao kalapona maʻamau i loko o nā mahina-pitting, pohā, hopu ʻia ma lalo o ka ea piha i ka chloride a i ʻole ka mahu ʻakika. ʻAʻole ka nīnau maoli ina e hahau ana ka palaha—oia i ka manawa, a pehea ka nui o ka manawa hoʻomaha, ke kumukūʻai hoʻoponopono, a me ka pilikia palekana e lawe mai ai. ʻO ia ke kumu i hoʻōki ai nā ʻenekinia ma Zibo Hongcheng Fan Co., Ltd. i ka hoʻolālā ʻana i nā mea pā "ʻoi aku ka pale ʻana i ka corrosion". Ua kūkulu lākou i nā mea hoʻoheheʻe anti-corrosion kila i hana ʻia no ka hoʻopaʻapaʻa ʻole: 316L mau hale kila kila, nā kumu, nā impellers, a me nā mea hoʻopaʻa; nā hili piha ʻana; nā ʻili i hoʻopaʻa ʻia; a me ke kaulike hoʻoikaika i hōʻoia ʻia i ka ISO 1940 G2.5. ʻAʻole ma ke ʻano he koho—akā ma ke ʻano he kumu.
No ke aha ʻaʻole "ʻoi aku ka maikaʻi" o ke kila kila - ʻaʻole hiki ke kūkākūkā i nā noi koʻikoʻi
Ua ʻike mākou i ʻekolu mau hiʻohiʻona hāʻule maʻamau i loko o nā hoʻonohonoho corrosive: ʻo ka mua, galvanic corrosion kahi e hoʻopili ai nā papa carbon-steel i nā impeller stainless-e hana ana i nā micro-currents e ʻai i nā hui weld. ʻO ka lua, ʻo ka ʻinoʻino i loko o nā flanges bolted i ʻike ʻia i ka condensate a me ka sulfur dioxide. ʻO ke kolu, ʻo ka māhā ʻana i ka pōʻino ma nā ʻau peʻahi ma lalo o ka hoʻouka wela cyclic a me ka ʻike H₂S. Hoʻopili nā mea pā epoxy-coated maʻamau i kēia mau pilikia-a hiki i ka uhi ʻana i nā pahu i ka wā o ka mālama ʻana a i ʻole ka paikikala wela, e hōʻike ana i ke kila maka ma lalo. Hoʻopau ka mea peʻahi anti-corrosion kila i ke kumu kumu: ʻaʻohe uhi e hoʻohaʻahaʻa, ʻaʻohe metala like ʻole i ka hui, ʻaʻohe pahele ʻino huna. Ma Zibo Hongcheng, ua hoʻohana ʻia kēlā me kēia mea hoʻoheheʻe FBD-Ⅱ no ka lawelawe hoʻoulu ʻana i ka lānahu e hoʻohana ana i ka 316L ducting a me ka impeller blades me ka liʻiliʻi o 2.5 mm ka mānoanoa o ka pā—ʻaʻole e pale wale i ka noe waikawa, akā no ke kū ʻana i nā ʻāpana abrasive me ka ʻole o ka lahilahi ma lalo o ka hoʻomanawanui ʻana.
Nā Koi Hoʻokō ʻOiaʻiʻo e hoʻohālike i kēlā me kēia hoʻoholo hoʻolālā
Hoʻopaʻapaʻa paha kekahi ʻoi aku ka nui o ke kila kila no ka haʻahaʻa haʻahaʻa. Akā, haʻi ka ʻikepili kahua i kekahi moʻolelo ʻē aʻe. I loko o kahi mea kanu kemika Shandong e holo mau ana i ka hana 24/7, ua lōʻihi ka peʻahi centrifugal i uhi ʻia i 14 mau mahina ma mua o ka lawe ʻana i ka pōʻino mai ka neʻe ʻana o ka chloride i ka momona. ʻO kāna mea hoʻololi i ke kila kila-corrosion—he ea hoʻokahi (28,000 m³/h), ke kaomi paʻa like (3,200 Pa), ka helu kaʻa like like (55 kW)—ua hana ʻo ia i 47 mahina me nā pani pani ʻole ʻia. No ke aha mai? No ka mea, ʻaʻole hoʻololi wale ʻo Zibo Hongcheng i nā mea. Hoʻolālā hou lākou: hoʻonui i nā hale halihali me nā sila lehelehe pālua i helu ʻia no IP68; nā sila labyrinth pili ʻole ma nā hoʻonui ʻia; a me nā ʻaoʻao o ka impeller blade i hoʻopaʻa ʻia no ka wikiwiki o ke kihi haʻahaʻa—e hōʻemi ana i ka ʻinoʻino me ka mālama pono ʻana. ʻO kā lākou 9-19 kiʻekiʻe-pressure stainless blower, hoʻohana nui ʻia ma ke ʻano he boiler poʻokela i nā mea kanu biomass-fired, hāʻawi i ka 84.3% peak efficiency ma 1,450 rpm-ʻaʻole naʻe me ka pale ʻana i ka corrosion, akā ma muli o ke aʻo ʻana i ka thermal a me ka mechanical design.
Hoʻopilikino i hana—ʻaʻole wale nā koi kūʻai aku
ʻO ka "Customizable" ke ʻano liʻiliʻi inā ʻaʻole ia e holo i ka manawa, kūpono i nā kikoʻī, a ola i ka hana ʻana. Ma Zibo Hongcheng, hoʻomaka ka hana maʻamau me ka ʻenehana noiʻi—ʻaʻole nā pepa kūʻai. I ka wā e pono ai ka hale hoʻoheheʻe titanium i nā mea pahū-hōʻoia kū'ē i ka mahu paʻakai hoʻoheheʻe ʻia ma 450°C, ʻaʻole i paʻa kā lākou hui i nā kikoʻī maʻamau. Ua nānā lākou i nā hōʻike hoʻokumu maoli ʻana o ke kinoea, ua hoʻopaʻa ʻia nā ʻoluʻolu wela ma waena o ka hale peʻa, ua koho ʻia ʻo Inconel 625 no nā cones inlet, hoʻohui i nā paepae i hoʻopaʻa ʻia i ka wai, a hōʻoia i ka hana ma ko lākou hale hoʻāʻo 1,200 kW-ana ana i ka vibration, piʻi ʻana o ka mahana, a me ka pohō o ke kaomi ma lalo o 72 mau hola i hoʻohālikelike ʻia. ʻAʻohe helu papa inoa ma waho o ka papa. ʻAʻole "e pili ana i ka loiloi ʻenehana." Hoʻopaʻa paʻa wale ʻia, hiki ke hana hou ʻia, hoʻokō ʻia i ke kahua. Loaʻa i kā lākou kōpili kila kila anti-corrosion fan nā ʻano like ʻole he 17 me nā palapala hōʻoia ATEX, IECEx, a i ʻole CCC-Mine—a ʻo kēlā me kēia moku me nā hōʻike hōʻike hōʻike mea hiki ke loaʻa (MTRs), nā palapala hōʻoia hoʻoikaika kino, a me nā pihi hana piha piha i pūlima ʻia e kekahi ʻenekini mīkini i hoʻopaʻa ʻia.
Hiki iā ʻoe ke hōʻoia—Ma mua o ke kau ʻana
Loaʻa ka hilinaʻi mai ka ʻike maopopo—ʻaʻole nā palapala. ʻO kēlā me kēia mea kila kila anti-corrosion fan mai Zibo Hongcheng e loaʻa i ʻehā mau mea hoʻopaʻa ʻia: hōʻoia ʻia ma o ka spectrometer XRF lima lima (e hōʻoia ana iā Mo ≥ 2.5%, Cr ≥ 16.5%, Ni ≥ 10.5%); ka nānā ʻana i ka dimensional me ka hoʻohana ʻana i nā mea paʻa i hōʻoia ʻia e CMM; ka ho'āʻo hana ma 110% helu wikiwiki no 30 mau minuke me ka nānā ʻana i ka vibration manawa maoli (<0.71 mm/s RMS ma ka wikiwiki hana); a me ka leak-check hope me ka helium mass spectrometry ma nā hili a pau i wili ʻia. ʻAʻohe mea e holo ʻole me ka QR-coded digital dossier e hoʻopili ana i nā wikiō hoʻāʻo, MTR scans, a me ka calibration logs. Pēlā ʻoe e pale aku ai i ka hewa $120,000: hoʻokomo i kahi peʻahi "stainless" wale nō e ʻike i ka baseplate ʻo 304-ʻaʻole 316L-a hāʻule i loko o ʻeono mahina ma kahi o kahi chlorine scrubber.
ʻAʻole pili ka ea ʻoihana e pili ana i ka neʻe ʻana o ka ea-e pili ana i ka hoʻomau ʻana i ka hoʻomau kaʻina hana, ka pale ʻana i nā limahana, a me ka pale ʻana i nā hemahema. ʻAʻole he kikowaena kumu kūʻai ke kila kila anti-corrosion fan. ʻO ia ka laina mua o ka pale ʻana i ka pilikia ʻōnaehana. Hoʻokumu ʻo Zibo Hongcheng Fan Co., Ltd. iā lākou ʻaʻole e hoʻokō i nā kūlana haʻahaʻa—akā e ola i nā lako a lākou e lawelawe ai. No ka mea i loko o nā wahi paʻakikī, ʻaʻole koho ka lōʻihi. ʻO ia wale nō ka mea nui.
