Kukula kwa msika wapadziko lonse wa ma compressor a mpweya ndi pafupifupi madola 44 biliyoni aku US mu 2023. Makampani aku China akunyumba akupitilizabe kukweza mphamvu zawo zopangira ndi kupanga, ndipo njira zapakhomo zikupita patsogolo nthawi zonse.Zinthu zosefera za compressor ya mpweya, monga zowonjezera zofunika, zimakhala ndi malo ofunikira mu unyolo wa mafakitale.
I. Zipangizo Zazikulu Zopangira Zosefera za Mpweya
Zinthu zofunika kwambiri pa fyuluta ya mpweya ndi pepala losefera lokonzedwa mwapadera, lomwe magwiridwe ake amatsimikizira mwachindunji momwe kusefera kudzakhudzira komanso nthawi yogwirira ntchito. Pakadali pano, fyuluta ya mpweya yodziwika bwino imapangidwa ndi kampani ya HV yochokera kunja ndi pepala losefera la Korean Ahlstrom. Mapepala osefera awa ali ndi makhalidwe aukadaulo awa:
Ma Parameters Omwe Ali ndi Thupi: Kulemera kwa pepala ndi 127 ± 6 g/m², makulidwe ≥ 0.36mm, kuya kwa corrugation 0.1 – 0.3mm, kulola mpweya kulowa pa △P = 200Pa condition ≥ 580L/m²·s, kukula kwakukulu kwa ma pore ≤ 75μm.
Kusefa: Kulondola kwa kusefa ndi 5 - 10μm, kugwiritsa ntchito bwino kusefa kumafika 98%, zomwe zimathandiza kuti tinthu tolimba tilowe mumlengalenga. Kapangidwe ka kapangidwe ka multilayer pleated kumawonjezera malo osefa ndi nthawi 5 - 8, ndipo mphamvu ya zinthu zoipitsa imawonjezeka kwambiri.
Makhalidwe Olimba: Nthawi yogwiritsidwa ntchito popanga zinthu ndi maola 2000, ndipo pamalo omwe mpweya wabwino uli bwino, imatha kuwonjezeredwa mpaka maola 3000. Pepala losefera limakutidwa ndi utomoni, wokhala ndi utomoni wa pafupifupi 18%, zomwe zimapangitsa kuti lisamavutike ndi madzi komanso likhale lolimba.
II. Zipangizo Zazikulu Zopangira Mafuta
Chida chachikulu chosefera cha zinthu zosefera mafuta ndi ulusi wagalasi. Makhalidwe ake aukadaulo ndi awa:
Kapangidwe ka Ulusi: Pogwiritsa ntchito ulusi wagalasi wopyapyala kwambiri wokhala ndi mainchesi a 1 - 20μm, kupanga gawo losefera kudzera mu kapangidwe kolumikizana ka magawo atatu, ndi kukula kwa ma pore a 30 - 80μm. Kapangidwe kameneka kangathe kuletsa madontho a mafuta a 99% ≥ 5μm, ndi mphamvu yoyezera kusefera ya 99.9%.
Kukana Kutentha Kwambiri: Ulusi wagalasi wokha umatha kupirira kutentha kwa 555℃, koma pogwiritsa ntchito zinthu zosefera, kutentha kogwira ntchito kumatha kufika 120℃ mothandizidwa ndi chimango chachitsulo chosapanga dzimbiri. Uli ndi kukana kwamphamvu kwa mankhwala ndipo umatha kukana mayankho a asidi ndi alkali ndi mayankho ena osakhala achilengedwe, oyenera kusefedwa kwa mafuta osiyanasiyana opaka mafuta ndi mafuta a hydraulic.
Kapangidwe ka Makina: Kuchuluka kwa kusweka kwa fracture kumawonjezeka kufika pa 3.5%, komwe ndi kokwera ndi 42% kuposa njira zachikhalidwe.
III. Zipangizo Zazikulu Zopangira Zosefera Zolekanitsa Mafuta ndi Gasi
Zinthu zosefera zolekanitsa mafuta ndi mpweya zimagwiritsa ntchito zosefera zagalasi zopangidwa ndi ulusi wopangidwa ndi ulusi wochuluka kwambiri kuchokera ku kampani ya US HV. Zili ndi makhalidwe awa:
Kapangidwe ka Zinthu: Kopangidwa ndi zipangizo zosefera zagalasi la ulusi wa micrometer mu kapangidwe kake ka multilayer composite, ndi ulusi wa mainchesi a 1 - 20μm, kupanga gawo losefera lokhala ndi magawo atatu kudzera mu njira zapadera. Kapangidwe kameneka kangathe kuletsa bwino tinthu ta mafuta tokhala ndi utsi wa 0.1μm, ndi mafuta olekanitsidwa a gasi okwana ≤ 3PPM w/w.
Njira Yolekanitsira: Kudzera mu kutsekereza, kufalitsa ndi kusonkhanitsa zinthu zitatu, madontho ang'onoang'ono amafuta amaphatikizidwa kukhala madontho akuluakulu amafuta. Tinthu tating'onoting'ono ta mafuta timayikidwa ndi chitoliro chamafuta chobwerera pansi ndikubwezedwa ku dongosolo lopaka mafuta. Kusiyana koyambirira kwa kuthamanga ndi ≤ 0.02MPa, kusiyana kwa kuthamanga kwa mpweya ndi 0.7MPa, ndipo nthawi yogwira ntchito ndi maola 3500 - 5200.
Kusinthasintha kwa Zachilengedwe: Yopirira pH 2 - 12 acidic ndi alkaline, yokhala ndi kuchuluka kwa kutupa kwa ≤ 5%. Mu mayeso a 5000 cycle, magwiridwe antchito amachepa ndi 12%, kuthamanga kwa ntchito ndi 1.4 - 2.5MPa, makamaka yoyenera m'malo ovuta a mafakitale monga mafakitale a petrochemical ndi magetsi.
IV. Zipangizo Zachiwiri ndi Zigawo Zothandizira
Wothandizira Kuchiza Utomoni: Utomoni uwu umapatsa zinthu zosefera mphamvu zosalowa madzi, umawonjezera mphamvu ya makina, komanso umathandizira kukana kutentha. Utomoni wa phenolic umatha kupirira kutentha kwa 280℃, kusunga bata kutentha kwambiri.
Dongosolo Lomatira: Kugwiritsa ntchito zomatira zomatira zotentha za mtundu wa EVA, PO kapena PA popangira zinthu zosefera. Zinthu zosefera mpweya nthawi zambiri zimagwiritsa ntchito zomatira zotentha za EVA, pomwe zinthu zosefera zamafuta zimagwiritsa ntchito zomatira zotentha za PA polyurethane. Zomatirazi zimakhala ndi kukhuthala kokhazikika pa kutentha komwe kwakhazikitsidwa ndipo zimapanga gawo lolimba lomangirira pambuyo pozimitsa, kuonetsetsa kuti kapangidwe ka zinthu zosefera kamakhala kolimba. Zowonjezera zothandiza: zimaphatikizapo zinthu zothira madzi, zinthu zoyera, zothira madzi ndi zoletsa moto, ndi zina zotero.
Zipangizo zomwe zili pamwambazi zimagwirira ntchito limodzi mu dongosolo kuti zitsimikizire kuti zinthu zosefera zikugwira ntchito bwino kwambiri pankhani yolondola kusefera, nthawi yogwirira ntchito komanso mphamvu ya makina. Chiŵerengero cholondola cha zipangizo zosiyanasiyana ndi njira zopangira zinthu ndizomwe zimagwiritsa ntchito kwambiri.
