Chii chinonzi "air filter"?
Sefa yemhepo mudziyo unobata zvinhu kuburikidza nekuita kwe porous sefa zvinhu uye kuchenesa mweya.Mushure mekucheneswa kwemhepo, inotumirwa mukati kuti ive nechokwadi chekuita zvinodiwa zvemakamuri akachena uye hutsanana hwemhepo mumakamuri akajairwa emhepo.Nzira dzekusefa dziri kuzivikanwa pari zvino dzinonyanya kuumbwa nemhedzisiro mishanu: interception effect, inertial effect, diffusion effect, gravity effect, uye electrostatic effect.
Zvinoenderana nezvinodiwa zvemaindasitiri akasiyana, mafirita emhepo anogona kupatsanurwa kuita sefa yekutanga, yepakati sefa, hepa sefa uye Ultra-hepa sefa.
Nzira yekusarudza air filter zvine musoro?
01. Sarudza zvine musoro kushanda kwemasefa pamatanho ese zvichienderana nemamiriro ekushandisa.
Mafirita ekutanga uye epakati: Anonyanya kushandiswa mukunatsa kufefetedza kwemhepo uye masisitimu emhepo.Basa ravo guru nderokudzivirira mafirita epasi uye nzvimbo inotonhorera yekudziya ndiro yeair conditioning unit kuti isavharwe uye kuwedzera hupenyu hwavo hwesevhisi.
Hepa/ultra-hepa sefa: inokodzera mamiriro ekushandisa ane hutsanana hwakanyanya zvinodiwa, senge air-conditioning terminal air supply nzvimbo munzvimbo isina huruva yakachena workshop muchipatara, zvemagetsi optics kugadzira, kunyatso gadzira chiridzwa uye mamwe maindasitiri.
Kazhinji, iyo terminal sefa inosarudza kuti mhepo yakachena sei.Iwo mafirita ekumusoro pamatanho ese anoita basa rekudzivirira kuwedzera hupenyu hwavo hwesevhisi.
Kushanda kwemasefa padanho rega rega kunofanirwa kugadziridzwa zvakanaka.Kana iyo dhizaini yehunyanzvi yematanho maviri ari padyo emafirita akasiyana zvakanyanya, nhanho yapfuura haizokwanisa kuchengetedza nhanho inotevera;kana musiyano pakati pezvikamu zviviri usina kunyanya kusiyana, danho rekupedzisira richaremerwa.
Iyo inonzwisisika kumisikidzwa ndeyokuti kana uchishandisa iyo "GMFEHU" kunyatso tsanangura rondedzero, isa yekutanga-level sefa yega 2 - 4 nhanho.
Pamberi pesefa yehepa pamagumo ekamuri yakachena, panofanira kuva nesefa ine hunyanzvi hwekuita isingasviki F8 kuidzivirira.
Kuita kwesefa yekupedzisira kunofanirwa kuve kwakavimbika, kushanda nesimba uye kumisikidzwa kweiyo pre-firita kunofanirwa kuve kunonzwisisika, uye kuchengetwa kwesefa yekutanga kunofanirwa kuve kuri nyore.
02. Tarisa pazvikamu zvikuru zvesefa
Yakatemerwa vhoriyamu yemhepo: Kune mafirita ane chimiro chakafanana uye yakafanana sefa zvinhu, kana kupikisa kwekupedzisira kwatemwa, nzvimbo yekusefa inowedzera ne50%, uye hupenyu hwesevhisi hwesefa huchawedzerwa ne70% -80%.Kana iyo sefa yapeta kaviri, hupenyu hwesefa hwesefa hunenge hurefu hwakapetwa katatu pane hwepakutanga.
Kwekutanga kuramba uye kuramba kwekupedzisira kwesefa: Iyo sefa inoumba kuramba kuyerera kwemhepo, uye kuunganidzwa kweguruva pasefa kunowedzera nenguva yekushandisa.Kana kushorwa kwesefa kunowedzera kune imwe kukosha kwakatarwa, sefa inoraswa.
Kupokana kwesefa itsva kunonzi "kutanga kuramba", uye kukosha kwekupikisa kunoenderana kana iyo sefa yaraswa inonzi "final resistance".Mamwe masefa samples ane "yekupedzisira kuramba" paramita, uye air conditioning mainjiniya anogona zvakare kushandura chigadzirwa zvinoenderana ne-on-saiti mamiriro.Iko kupikisa kwekupedzisira kukosha kwekugadzirwa kwepakutanga.Muzviitiko zvakawanda, kupikisa kwekupedzisira kwesefa inoshandiswa panzvimbo yacho ndeye 2-4 nguva yekutanga kupikisa.
Inokurudzirwa kuramba kwekupedzisira (Pa)
G3-G4 (sefa yekutanga) 100-120
F5-F6 (pakati sefa) 250-300
F7-F8 (yakakwirira-yepakati sefa) 300-400
F9-E11 (sub-hepa sefa) 400-450
H13-U17 (hepa sefa, Ultra-hepa sefa) 400-600
Kushanda kwesefa: Iyo "filtration performance" yefefa yemhepo inoreva chiyero chehuwandu hweguruva rakabatwa nesefa kune guruva remukati memhepo yekutanga.Iko kutsunga kwekuita kusefa hakuparadzaniswe kubva kune yekuyedza nzira.Kana iyo sefa imwe chete yakayedzwa uchishandisa nzira dzakasiyana dzekuyedza, hunhu hunobudirira hunowanikwa huchasiyana.Naizvozvo, pasina nzira dzekuyedza, kusefa kwesefa hakugone kutaura nezvazvo.
Dust holding capacity: Hupfu hunobata simba resefa zvinoreva huwandu hunotenderwa kuunganidza huruva hwesefa.Kana iyo guruva yekuunganidza huwandu ichipfuura kukosha uku, kupikisa kwesefa kuchawedzera uye kushanda kwesefa kunoderera.Naizvozvo, zvinogarotemerwa kuti guruva rinobata simba resefa rinoreva huwandu hweguruva rinounganidzwa kana kuramba nekuda kwekuunganidzwa kweguruva kunosvika pamutengo wakatarwa (kazhinji kaviri kupikisa kwekutanga) pasi pehumwe vhoriyamu yemhepo.
03. Tarisa kuongorora kwesefa
Pane nzira dzakawanda dzekuyedza kusefa kusefa kuita zvakanaka: gravimetric nzira, yemhepo yekuverenga guruva nzira, kuverenga nzira, photometer scanning, kuverenga scanning nzira, nezvimwe.
Kuverenga Scan Method (MPPS Method) Yakanyanya Penetratiable Particulate Size
Nzira yeMPPS parizvino ndiyo nzira yekuedza mafirita ehepa munyika, uye ndiyo nzira yakaomesesa yekuyedza mafirita ehepa.
Shandisa counter kuti urambe uchitarisa uye kuongorora iyo yese mhepo yekubuda pamusoro pesefa.Kaunda inopa nhamba uye saizi yeguruva panzvimbo yega yega.Iyi nzira haigone kuyera chiyero chekushanda kwesefa, asiwo kuenzanisa kushanda kwenzvimbo yeimwe neimwe poindi.
