He aha ke kiʻekiʻe maʻemaʻe pōpō pōlele? ʻO ka High Purity Ball Valve kahi mea hoʻokele kahe e kū ana i nā kūlana o ka ʻoihana no ka hoʻomaʻemaʻe mea a me ka hoʻolālā.
Hoʻohana ʻia kēia mau mea i nā "ʻōnaehana kākoʻo" e like me ka hoʻomaʻamaʻa ʻana i ka mahu hoʻomaʻemaʻe no ka hoʻomaʻemaʻe ʻana a me ka mālama ʻana i ka mahana.
He aha ka maʻamau o ka ʻoihana no nā valve maʻemaʻe kiʻekiʻe? Loaʻa i ka ʻoihana lāʻau lapaʻau nā koho koho valve mai nā kumu ʻelua:
ʻO ka ASME/BPE-1997 kahi palapala normative e ulu ana e uhi ana i ka hoʻolālā a me ka hoʻohana ʻana i nā mea hana i ka ʻoihana lāʻau lapaʻau. hoʻonui… a he ʻāpana koʻikoʻi o ka hana ʻana i nā huahana, e like me ka wai no ka injection (WFI), ka mahu maʻemaʻe, ka ultrafiltration, ka waiho ʻana o nā huahana waena a me nā centrifuges.
I kēia lā, hilinaʻi ka ʻoihana i ka ASME / BPE-1997 e hoʻoholo i nā hoʻolālā pōlele pōlele no nā noi hoʻopili ʻole huahana. ʻO nā wahi nui i uhi ʻia e ka kikoʻī:
Hoʻohana pinepine ʻia nā kiwi i loko o nā ʻōnaehana kaʻina biopharmaceutical me nā kiwi pōpō, nā kiwi diaphragm, a me nā kiwi hoʻopaʻa.
ʻO ka hōʻoia he kaʻina hana hoʻoponopono i hoʻolālā ʻia e hōʻoia i ka reproducibility o kahi huahana i hoʻoponopono ʻia a i ʻole formulation. Hōʻike ka papahana e ana a nānā i nā ʻāpana kaʻina hana mechanical, ka manawa hoʻolālā, ka mahana, ke kaomi a me nā kūlana ʻē aʻe.
Aia kekahi mau pilikia e pili ana i ka hōʻoia mea. ʻO ka MTR (Material Test Report) he ʻōlelo ia mai kahi mea hana hoʻoheheʻe e palapala i ke ʻano o ka hoʻolei ʻana a hōʻoia i hele mai ia mai kahi holo kikoʻī i ke kaʻina hana hoʻolei.
Hāʻawi nā mea hana mea noho i nā hōʻike haku no ka hōʻoia ʻana i ka mālama ʻana o ka noho me nā alakaʻi FDA.
ʻO ka Ultra High Purity (UHP) kahi huaʻōlelo i manaʻo ʻia e hoʻoikaika i ka pono o ka maʻemaʻe kiʻekiʻe loa.
Loaʻa ka ʻoihana semiconductor i nā kikoʻī hoʻolālā valve mai ka hui ʻana o ka ʻike i mālama ʻia e ka hui SemaSpec. ʻO ka hana ʻana o nā wafers microchip e pono ai ka mālama pono ʻana i nā kūlana e hoʻopau a hōʻemi paha i ka hoʻohaumia ʻana mai nā particles, outgassing a me ka wai.
Hōʻike ka SemaSpec maʻamau i ke kumu o ka hoʻokumu ʻana i nā ʻāpana, ka nui o ka nui, ke kumu kinoea (ma o ka hui ʻana o ka valve palupalu), ka hoʻāʻo ʻana o ka helium leak, a me ka wai ma loko a ma waho o ka palena o ka valve.
Ua hōʻoia maikaʻi ʻia nā kīpē pōleʻa i nā noi paʻakikī. ʻO kekahi o nā pōmaikaʻi nui o kēia hoʻolālā:
Mechanical Polishing - ʻO nā ʻili i poni ʻia, nā weld a me nā ʻili i hoʻohana ʻia he mau hiʻohiʻona ili like ʻole ke nānā ʻia ma lalo o ke aniani hoʻonui.
Hana ʻia ka hana polishing mechanical ma ka hoʻohana ʻana i ka alumina abrasives. Hiki ke hoʻokō ʻia ka polishing mechanical e nā mea hana lima no nā wahi ākea nui, e like me nā reactors a me nā moku ma kahi, a i ʻole e nā reciprocators aunoa no nā paipu a i ʻole nā ​​ʻāpana tubular.
ʻO ka electropolishing ka wehe ʻana i nā mea ʻino microscopic mai nā ʻili metala ma nā ʻano electrochemical.
Kūleʻa maoli ke kila kila i ka corrosion ma muli o kona kiʻekiʻe chromium maʻiʻo (maʻamau 16% a ʻoi aku paha i ke kila kila).
ʻO ka hopena o kēlā me kēia kaʻina hana polishing ka hana ʻana i kahi ʻili "maʻemaʻe" i wehewehe ʻia e like me ka awelika roughness (Ra). Wahi a ASME / BPE;"E hōʻike ʻia nā poli a pau ma Ra, microinches (m-in), a i ʻole micrometers (mm)."
Ana 'ia ka laumania o ka ili me ka profilometer, he mea hana 'akomi me ka stylus-style reciprocating arm. Ua hele ka stylus ma ka ili metala e ana i ke kiekie o ke awawa.
Hōʻike ʻia ka pilina ma waena o ka ʻili i hoʻomaʻamaʻa ʻia a me ka poni ʻia, ka helu o nā hua abrasive a me ka ʻili o ka ʻili (ma mua a ma hope o ka electropolishing) i hōʻike ʻia ma ka papa ma lalo.
ʻO nā micrometers kahi maʻamau maʻamau o ʻEulopa, a ua like ka ʻōnaehana metric me nā microinches. Hoʻokahi microinch e like me 40 micrometers.
Ma muli o ke ʻano maʻalahi o ka hoʻolālā ʻana i ka pōlele, hiki ke loaʻa i nā ʻano noho like ʻole, sila a me nā mea kino.
Makemake ka ʻoihana biopharmaceutical e hoʻokomo i nā "pūnaewele i hoʻopaʻa ʻia" i nā manawa a pau. hoʻonohonoho ʻia.
Loaʻa nā lako Cherry-Burrell ma lalo o nā inoa inoa "I-Line", "S-Line" a i ʻole "Q-Line" no nā ʻōnaehana maʻemaʻe kiʻekiʻe e like me ka ʻoihana meaʻai / mea inu.
ʻO nā hopena hoʻopaneʻe i waho o waho (ETO) hiki ke hoʻopaʻa ʻia i loko o ka laina i loko o ka ʻōnaehana paipu. E like ka nui o nā hopena ETO e like me ke anawaena o ka ʻōnaehana paipu (pipe) a me ka mānoanoa o ka pā.
Hoʻohana nui ʻia nā kiwi pōleʻa i nā noi kaʻina ma muli o kā lākou versatility.
Eia hou, hiki ke hoʻoneʻe ʻia ka ʻāpana waena o ka pōleʻa e ʻae i ke komo ʻana i ka pahu weld kūloko, a laila hiki ke hoʻomaʻemaʻe ʻia a/a i ʻole hoʻi.
He mea nui ka hoʻoheheʻe wai no ka mālama ʻana i nā ʻōnaehana bioprocessing i ka maʻemaʻe a me ka sterile. ʻO ka wai i koe ma hope o ka hoʻoheheʻe ʻana e lilo ia i wahi colonization no ka bacteria a i ʻole microorganisms ʻē aʻe, e hana ana i kahi bioburden hiki ʻole ke ʻae ʻia ma ka ʻōnaehana.
Ua wehewehe ʻia kahi wahi make i loko o kahi ʻōnaehana paipu ma ke ʻano he groove, tee, a i ʻole ka hoʻonui ʻana mai ka holo paipu nui ma mua o ka nui o ke anawaena paipu (L) i wehewehe ʻia i ka ID paipu nui (D).
Hoʻolālā ʻia nā mea hoʻoheheʻe ahi i mea e pale ai i ka hoʻolaha ʻana o nā wai wela i ka wā o ke kaʻina hana.
FDA-USP23, Papa VI i apono 'ia i ka noho poepoe no ka noho ana: PTFE, RTFE, Kel-F, PEEK a me TFM.
ʻO TFM kahi PTFE i hoʻololi ʻia i kemika e hoʻopili ana i ke āpau ma waena o ka PTFE kuʻuna a me ka hoʻoheheʻe ʻana i ka PFA. Ua hoʻokaʻawale ʻia ʻo TFM ma ke ʻano he PTFE e like me ASTM D 4894 a me ISO Draft WDT 539-1.5. Hoʻohālikelike ʻia me PTFE kuʻuna, loaʻa iā TFM nā waiwai i hoʻonui ʻia:
Ua hoʻolālā ʻia nā noho i piha i ka lua e pale aku i ke kūkulu ʻia ʻana o nā mea, i ka wā e paʻa ai ma waena o ka pōleʻa a me ka lua o ke kino, hiki ke hoʻopaʻa a paʻa paha i ka hana maʻemaʻe o ka lālā pani pani.
No ka hana maʻamau, loaʻa nā ʻano mea hana ʻelua: pneumatic a me ka uila. Hoʻohana nā mea hana pneumatic i kahi piston a i ʻole diaphragm i hoʻopili ʻia i kahi mīkini hoʻololi e like me ka rack a me ka hoʻonohonoho pinion e hāʻawi i ka rotational output torque.Electric actuators are basically gear motors. ve Actuator" ma hope o kēia manual.
Hiki ke hoʻomaʻemaʻe ʻia a hoʻopaʻa ʻia nā kiʻi kiʻekiʻe Purity Ball Valves i nā koi BPE a i ʻole Semiconductor (SemaSpec).
Hana ʻia ka hoʻomaʻemaʻe kumu me ka hoʻohana ʻana i kahi ʻōnaehana hoʻomaʻemaʻe kani ultrasonic e hoʻohana ana i kahi reagent alkaline i ʻae ʻia no ka hoʻomaʻemaʻe anuanu a me ka degreasing, me kahi ʻano ʻokoʻa ʻole.
Hōʻailona ʻia nā ʻāpana kaomi me ka helu wela a ua hui pū ʻia me kahi palapala hōʻoia kūpono.
I kekahi manawa, pono e koho nā ʻenekini kaʻina hana ma waena o ka pneumatic a i ʻole ka uila uila no nā ʻōnaehana mana kaʻina.
ʻO ka hana mua i ke koho ʻana i ke ʻano o ka mea hana (pneumatic a i ʻole uila) ʻo ia ka hoʻoholo ʻana i ke kumu mana kūpono loa no ka mea hana. ʻO nā mea nui e noʻonoʻo ai:
ʻO nā mea hana pneumatic kūpono loa e hoʻohana i ka hāʻawi ʻana i ke ea o 40 a 120 psi (3 a 8 bar). ʻO ka maʻamau, ua nui lākou no ka hoʻolako ʻana o 60 a 80 psi (4 a 6 bar).
Hoʻohana maʻamau ʻia nā mea hana uila me ka mana 110 VAC, akā hiki ke hoʻohana ʻia me nā ʻano ʻokoʻa AC a me DC, ʻelua a me ʻekolu-phase.
Hiki ke hoʻohanaʻia nā mea hana pneumatic a me ka uila ma luna o ka laulā wela. e ka wela helu okoa ma mua o ka actuator, a me keia e lawe i loko o ka mooolelo i loko o nā noi a pau. Ma nā haʻahaʻa wela noi, ea lako maikaʻi e pili ana i ka hau wahi e noonoo.
Loaʻa i nā mea hana uila ke ana wela o -40 a 1500F (-40 a 650C). Ke hoʻohana ʻia i waho, pono e hoʻokaʻawale ʻia ka mea hoʻokele uila mai ke kaiapuni i mea e pale ai i ka wai mai ke komo ʻana i loko o ka hana. i ka wā ʻaʻole ia e holo ana, hiki i ka hoʻololi ʻana o ka mahana ke hana i ke kaiapuni e "hanu" a condense.
He mea paʻakikī i kekahi manawa ke hōʻoia i ka hoʻohana ʻana i nā mea hana uila i nā wahi pōʻino, akā inā ʻaʻole hiki ke hāʻawi i nā ʻano hana i koi ʻia e ka ea i hoʻopaʻa ʻia a i ʻole nā ​​​​mea hana pneumatic, hiki ke hoʻohana ʻia nā mea hana uila me nā hale hoʻonohonoho kūpono.
Ua hoʻokumu ka National Electrical Manufacturers Association (NEMA) i nā alakaʻi no ke kūkulu ʻana a me ka hoʻokomo ʻana i nā mea hana uila (a me nā mea uila ʻē aʻe) no ka hoʻohana ʻana i nā wahi pōʻino. ʻO nā alakaʻi NEMA VII penei:
VII Wahi Pohihihi Ka Papa I (Explosive Gas or Vapor) e halawai me ke Code Uila Lahui no na noi;e hoʻokō i nā kikoʻī o Underwriters' Laboratories, Inc. no ka hoʻohana ʻana me ka ʻaila, hexane, naphtha, benzene, butane, propane, acetone, Atmospheres of benzene, lacquer solvent vapors a me ke kinoea maoli.
Loaʻa i nā mea hana hoʻokele uila ke koho o kahi mana NEMA VII kūpono o kā lākou laina huahana maʻamau.
Ma ka lima 'ē aʻe, pneumatic actuators inherently explosion-proof. Ke hoʻohana 'ia nā mana uila me ka pneumatic actuators ma nā wahi pōʻino, pinepine lākou iʻoi aku ka maikaʻi ma mua o nā mea hoʻokele uila. ʻO nā uators ma nā wahi pōʻino ke koho pono iā lākou i kēia mau noi.
ʻO ka hoʻihoʻi ʻana o ka puna.
Inā ʻaʻole hiki ke hoʻohana ʻia kahi pūnāwai ma muli o ka nui a i ʻole ke kaumaha o ka mea hana, a i ʻole i hoʻokomo ʻia kahi ʻāpana hana pālua, hiki ke hoʻokomo ʻia kahi pahu accumulator e mālama i ke kaomi ea.
