Ngatitaurei nezve kusefa inoshanda, kumhanya kwepamusoro uye kusefa velocity yehepa mafirita. Hepa filters uye ulpa filters zvinoshandiswa pamagumo eimba yakachena. Mafomu avo ezvimiro anogona kukamurwa kuita: mini pleat hepa sefa uye yakadzika pleat hepa sefa.
Pakati pazvo, maitiro ekuita kwehepa mafirita anoona maitiro avo epamusoro-soro ekusefa, saka kudzidza kwemaitiro ekuita kwehepa mafirita kune kukosha kukuru. Iyi inotevera sumo pfupi yekusefa zvakanaka, kumhanya kwepamusoro, uye kusefa velocity yehepa mafirita:
Surface velocity uye sefa velocity
Kumhanya kwepamusoro uye kusefa kwesefa kwehepa kunogona kuratidza huwandu hwekuyerera kwemhepo yehepa sefa. Velocity yepamusoro inoreva kuyerera kwemhepo pachikamu chehepa sefa, inowanzoratidzwa mu m/s, V=Q/F*3600. Kumhanya kwepamusoro chinhu chakakosha parameter inoratidza maitiro eiyo hepa sefa. Velocity yesefa inoreva kumhanya kwekuyerera kwemhepo pamusoro penzvimbo yesefa zvinhu, zvinowanzoratidzwa muL/cm2.min kana cm/s. Iyo sefa velocity inoratidza kupfuura kugona kweiyo sefa zvinhu uye kusefa kuita kweiyo sefa zvinhu. Iyo filtration rate yakaderera, kazhinji kutaura, kugona kwepamusoro kunogona kuwanikwa. Iyo filtration rate inobvumirwa kupfuura yakaderera uye kushorwa kwesefa zvinhu kwakakura.
Sefa kunyatsoshanda
Iyo "sefa inoshanda" yehepa sefa chiyero chehuwandu hweguruva rakabatwa kune guruva riri mumhepo yepakutanga: kusefa kunyatsoshanda = huwandu hweguruva rakabatwa nehepa sefa / guruva riri mumhepo iri kumusoro = 1-guruva riri mukati. mhepo yakadzika/kumusoro. Zvinoreva kushanda kweguruva remhepo zvinoita sezviri nyore, asi zvazvinoreva uye kukosha zvinosiyana zvakanyanya zvichienderana nenzira dzakasiyana dzekuedza. Pakati pezvinhu zvinotaridza kushanda kwesefa, "huwandu" hweguruva hune zvirevo zvakasiyana, uye hunhu hwemafirita ehepa akaverengerwa nekuyerwa anosiyanawo.
Mukuita, kune huremu hwose hweguruva uye nhamba yeguruva zvidimbu; dzimwe nguva huwandu hweguruva hweimwe yakajairika particle size, dzimwe nguva huwandu hweguruva rose; kunewo chiyero chechiedza chinoratidza zvisina kunanga kusungirirwa uchishandisa imwe nzira, fluorescence quantity; kune huwandu hwepakarepo hweimwe nyika, uye kune zvakare yakayerwa avhareji yehuwandu hwehukoshi hwehuhu hwese hwekugadzira guruva.
Kana iyo hepa sefa yakayedzwa uchishandisa nzira dzakasiyana, zviyero zvakayerwa zvinozosiyana. Nzira dzekuyedza dzinoshandiswa nenyika dzakasiyana siyana uye vagadziri hadzina yunifomu, uye kududzira uye kutaura kwehepa sefa inoshanda zvakasiyana. Pasina nzira dzekuyedza, kushanda kwesefa hazvibviri kutaura nezvazvo.
