Sefa chinhu inyanzvi izwi rekusefa nekuchenesa basa.Kuti uchenese iyo yakapusa uye yakapusa yekuparadzanisa mudziyo wezviwanikwa uye zviwanikwa zveyekutanga fluid, iyo sefa chinhu chinonyanya kushandiswa mukusefa kwemafuta, kusefa kwemhepo, kusefa kwemvura uye mamwe maindasitiri ekusefa.

Iyo sefa inogona kuparadzanisa zvimedu zvakasimba mumvura kana gasi, kana kuita kuti zvinhu zvakasiyana-siyana zvibatane zvizere kuti ikurumidze kuita nguva, izvo zvinogona kudzivirira kushanda kwakajairika kwemidziyo kana kuchena kwemhepo.Kana iyo mvura ichipinda musefa ine imwe saizi sefa, tsvina yayo inovharika, uye mvura yakachena inoyerera ichibuda kuburikidza nesefa element.Iyo liquid filter element inoita kuti mvura (kusanganisira mafuta, mvura, nezvimwewo) ichene kune iyo nyika inodiwa nekugadzirwa uye hupenyu, ndiko kuita kuti mvura isvike kumwe kuchena.

Air filter element inonziwo air filter cartridge, air filter, style, etc. Inonyanya kushandiswa kusefa kwemhepo muinjiniya locomotive, mota, zvekurima locomotive, marabhoritari, sterile operation room uye akasiyana siyana maoperation rooms.

Iyo sefa sikirini inonyanya kugadzirwa newaya mesh.Basa rayo guru nderokusefa kusvibiswa kwemidziyo uye kuvandudza kupikisa kwekuyerera kwezvinhu, kuitira kuti uvandudze kushanda kwesefa yemidziyo uye kurebesa hupenyu hwayo hwebasa.Sefa sikirini inoshandiswa zvakanyanya muhupenyu uye kugadzirwa, senge chikafu, mushonga, kugadzira michina uye mamwe minda, sefa skrini yakakosha.

Sefa inogona kupatsanurwa muzvikamu zvakasiyana zvichienderana nezvinhu zvakasiyana, zvinosanganisira simbi rabha sefa, kufefetedza sefa, simbi sefa, air conditioning sefa, coarse efficient filter, etc. mafirita akasiyana ane maitiro akasiyana uye chiyero chekushandisa.Iyo simbi yerubha sefa sikirini inonyanya kugadzirwa nesimbi isina simbi waya, iyo ine hunhu hwekupokana nekuora, kupisa kwakanyanya uye simba rakawanda.Iyo inowanzoenderana negasi uye mvura kusefa.Paunenge uchichenesa, iyo simbi yerubha sefa sikirini iri nyore kudzoreredza iyo yekutanga density, iri nyore kuchenesa.Ventilation filter inonyanya kugadzirwa nefiber textile, iine hunhu hwekusaita corrosion resistance, asidhi uye alkali kuramba, uye sefa yekufemesa ine mutengo wakakura wekuita, unogona kucheneswa kakawanda pasina kukanganisa kusefa, saka inofarirwa zvakanyanya neveruzhinji.Chinhu chikuru chesimbi sefa ialuminium foil kana simbi isina tsvina, inova chigadzirwa chakajairika mumidziyo yakawanda.Iyo inozivikanwa kune veruzhinji uye ine mukurumbira wemusika wepamusoro.Iyo air conditioning filter screen inonyanya kutora concave convex huchi chimiro, iyo inonyanya kushandiswa mukuchenesa tsvina system uye air filtration system.Zviri nyore kuchenesa uye kutsiva kakawanda uye ine nguva yakareba inomhanya, inodiwa zvakanyanya neveruzhinji.Coarse effect sefa inowanzoshanda kune yekutanga mhedzisiro yekusefa kwemidziyo, senge yakashata huruva kusefa uye kufefeta kwemhepo.Iko kukwenenzverwa kweiyo coarse effect sefa haina kukwirira, saka zvinodikanwa kugara uchitarisa kupfeka kwemidziyo mukushandisa.

Mukuita kwehupenyu hwezuva nezuva, iyo sefa inodawo kugara ichigadziriswa, kuitira kuti inyatso kuona kuti kusefa kwemidziyo haina kukanganiswa.Kazhinji, unofanira kuchenesa sefa mwedzi mitatu yega yega.Kutanga, bvisa sefa.Kana pasina tsvina yakawanda, unogona kuishambidza zvakananga nemvura yakachena, uye wozoomesa mumumvuri.Kana pane sediment yakawanda pamusoro pesefa, unogona kuipukuta nemucheka, woisuka nemvura yakachena, kana kushandisa chaiyo sefa yekuchenesa kuti icheneswe, uye woiisa munzvimbo inotonhorera kuti iome.Paunenge uchiisa iyo sefa skrini, inofanirwa kuiswa nenzira kwayo maererano nemirairo.Inofanirwa kuve nechokwadi chekuisa chisimbiso pane isina chinhu chibatiso chemidziyo kudzivirira kubuda kwemhepo.
Sefa inoita basa rakakosha muhupenyu.Iyo sefa inobatanidza matekinoroji mazhinji echizvino-zvino, inonyatso adsorbi guruva uye zvinhu zvine chepfu mumhepo, inova nechokwadi chehupenyu, inonatsiridza kuita kusefa kwemidziyo, uye zvakare inovandudza kugadzirwa kwakanaka.Ndinotenda kuti kuvandudzwa kwesefa kuchava nani uye zviri nani, nzvimbo yemusika icharamba ichivandudza.
