Kukura kwemusika wepasi rose wemakompresa emhepo kunosvika mabhiriyoni makumi mana nemana emadhora ekuAmerica muna 2023. Makambani ekuChina ari kuramba achivandudza kugona kwawo kugadzira uye nhanho yekugadzira, uye maitiro emuno ari kuramba achifambira mberi.Zvinhu zvefirita yecompressor yemhepo, sezvinhu zvinokosha, zvine chinzvimbo chakakosha muketani yemaindasitiri.
I. Zvinhu Zvikuru Zvisina Kugadzirwa zveAir Filter Elements
Chinhu chikuru chezvinhu zve air filter paper chakagadzirwa nemazvo, icho chinotarisa zvakananga mhedzisiro yekusefa uye hupenyu hwebasa. Parizvino, zvinhu zve air filter zvinogadzirwa nekambani yeHV inotengeswa kunze kwenyika uye pepa rekusefa reKorean Ahlstrom pure wood pulp. Mapepa aya e filter ane hunhu hunotevera:
Zvimiro zvemuviri: Huremu hwepepa i127 ± 6 g/m², ukobvu ≥ 0.36mm, kudzika kwecorrugation 0.1 – 0.3mm, kubvumidzwa kwemhepo pa △P = 200Pa mamiriro ≥ 580L/m²·s, saizi yepamusoro yepore ≤ 75μm.
Kushanda Kwekusefa: Kururama kwekusefa kuri 5 - 10μm, kushanda zvakanaka kwekusefa kunosvika 98%, zvichibatsira kudzivirira zvidimbu zvakasimba mumhepo. Dhizaini yechimiro chine mativi akawanda inowedzera nzvimbo yekusefa nekashanu kusvika kasere, uye kugona kwekusvibisa kunovandudzwa zvakanyanya.
Hunhu Hwekugara: Hupenyu hwebasa rekugadzira hunosvika maawa 2000, uye munzvimbo ine mhepo yakanaka, inogona kuwedzerwa kusvika maawa 3000. Pepa rekusefa rinorapwa neresin, rine resin inosvika 18%, zvichiita kuti rirambe risingapindi mvura uye rigare zvakanaka.
II. Zvinhu Zvikuru Zvisina Kugadzirwa zveZvinhu zveFirita yeOiri
Chinhu chikuru chinosefa mafuta chinoshandiswa mufiriji yegirazi. Hunhu hwayo hwehunyanzvi ndeinotevera:
Maumbirwo eFiber: Kushandisa fiber dzegirazi dzakapfava zvikuru dzine dhayamita ye1 - 20μm, zvichiita sefa rakapinda nepachivakwa chine mativi matatu, chine saizi yepore ye30 - 80μm. Chivakwa ichi chinogona kubata madonhwe emafuta e99% ≥ 5μm, nekushanda kwakayerwa kwekusefa kwe99.9%.
Kuramba Kupisa: Magirazi pachawo anogona kumira tembiricha yepamusoro ye555℃, asi kana uchishandisa zvinhu zvefirita, tembiricha yekushanda inogona kusvika 120℃ ichitsigirwa nefuremu yesimbi isingatsvi. Inodzivirira ngura yemakemikari zvakanyanya uye inogona kuramba mhinduro dzeacid nealkali nedzimwe mhinduro dzisiri dzeorganic, dzakakodzera kusefa mafuta akasiyana-siyana ekuzora nemafuta ehydraulic.
Hunhu hweMichina: Mwero wekureba kwekukuvara kwemapfupa unowedzerwa kusvika pa3.5%, 42% yakakwira kupfuura maitiro echinyakare.
III. Zvinhu Zvikuru Zvisina Kugadzirwa zveMafuta neGasi
Zvinhu zvemafirita ekuparadzanisa oiri negasi zvinoshandisa zvinhu zvemafirita egirazi akagadzirwa nefiber composite zvakapfava zvikuru kubva kukambani yeUS HV. Zvine hunhu hunotevera:
Kuumbwa Kwezvinhu: Yakagadzirwa nezvinhu zvema micrometer-level glass fiber filter muchimiro che multi-layer composite, ine fiber dhayamita ye 1 - 20μm, ichigadzira three-dimensional interlaced filtering layer kuburikidza nemaitiro akakosha. Chimiro ichi chinogona kubata zvinobudirira 0.1μm-size oil mhute particles, ine gasi remafuta re ≤ 3PPM w/w.
Nzira yekuparadzanisa: Kuburikidza nekupindira, kupararira uye kuunganidzwa kwemafuta, madonhwe madiki emafuta anounganidzwa kuita madonhwe makuru emafuta. Zvidimbu zvemafuta zvinoiswa papombi yemafuta inodzoserwa pasi uye zvinodzoserwa kuhurongwa hwekuzora. Musiyano wekutanga wekumanikidzwa i ≤ 0.02MPa, musiyano wekudzvanya wekutsiva i 0.7MPa, uye hupenyu hwebasa i 3500 - 5200 maawa.
Kuchinjika Kwezvakatipoteredza: Inokwanisa kushivirira pH 2 - 12 acidic uye alkaline environments, ine mwero wekuzvimba we ≤ 5%. Muongororo dze5000 cycle, mashandiro anongopera ne12% chete, kumanikidzwa kwekushanda kuri pakati pe1.4 - 2.5MPa, kunyanya yakakodzera munzvimbo dzakaoma dzemaindasitiri dzakadai semaindasitiri epetrochemical nemagetsi.
IV. Zvishandiso zvechipiri neZvimwe Zvikamu zvekubatsira
Mushonga weKurapa Resin: Maresini aya anopa zvinhu zvekusefa hunhu hwemvura, anowedzera simba remuchina, uye anovandudza kuramba tembiricha. Phenolic resin inogona kutsungirira 280℃, ichichengetedza kugadzikana pakupisa kwakanyanya.
Sisitimu Inonamira: Kushandisa zvinonamira zvinopisa zvinonyunguduka zveEVA, PO kana PA pakusanganisa zvinhu zvinosefa. Zvinhu zvinosefa zvemhepo zvinonyanya kushandisa chinonamira chinonyunguduka chinonyunguduka cheEVA, nepo zvinhu zvinosefa zvemafuta zvichishandisa chinonamira chinonyunguduka chePA polyurethane. Zvinonamira izvi zvine viscosity yakagadzikana patembiricha yakatarwa uye zvinoumba jira rakasimba rekubatanidza mushure mekuoma, zvichivimbisa kusimba kwechimiro chechinhu chinosefa. Zvimwe zvinowedzerwa zvinoshanda: zvinosanganisira zvinodzivirira mvura, zvinochenesa, zvinoparadzira uye zvinodzora moto, nezvimwewo.
Zvinhu zviri pamusoro apa zvinoshanda pamwe chete muhurongwa hwekuona kuti zvigadzirwa zve filter zvinobudirira zvakanaka maererano nekunyatso pfapfaidza, hupenyu hwebasa uye simba remuchina. Chiyero chaicho chezvinhu zvakasiyana uye matekiniki ekugadzirisa ndiwo matekiniki makuru.
