Iyo filtration system yakakosha kumichina zvekuti mimwe yatobva kufekitari.Asi mamiriro ekushanda anosiyana zvakanyanya, uye kana iri michina mikuru, zvakajairika kuti vabatanidzwe nemamiriro akanyanya.Kunyura mumakore akakora eguruva redombo- sekumigodhi-uye ivhu mumachina ekurima nemasango kana masara e soot kubva mukutsva kweinjini- semumarori nemabhazi- zvinhu izvi zvinokumbirwa nenzira dzisingaverengeki nemamiriro ekunze uye nekushanda pachako.
Kuve nechokwadi chekuti sisitimu inoshanda pamazinga akanakisa, zvakakosha kuve nemasefa akasiyana masisitimu.Tsvaga pazasi kuti mutsauko uripo pakati pesefa yepasi uye yakadzika sefa ndeipi uye kuti chimwe nechimwe chinotora basa ripi kuitira kuti ikubatsire kuzadzisa zvaunowana.
Chii chinonzi surface filter?
Isu tinotoziva kuti mafirita emakina akakura midziyo yakabatana kune akasiyana masisitimu ekuyerera kwemvura: mweya, lubricant uye mafuta.Saka, kuti kusefa kuitike zvinobudirira, svikiro rekusefa rinodikanwa, kureva kuti, chinhu chinozochengeta zvimedu zvinosvibisa.
Kune akati wandei mhando dzezvinhu zvinogadzira mafirita zvinhu: cellulose, polymers, fiberglass, pakati pevamwe.Nyaya yacho inobva pane chinangwa.Mukusefa mafuta muinjini dzinopisa, semuenzaniso, kushandiswa kwemasefa emapepa kwakajairika.Mune microfiltration, kune rumwe rutivi, yakawanda yegirazi microfiber inoshandiswa.
Muchidimbu, kusefa inzira yekumanikidza kufamba kwemvura kana gasi kuburikidza neine porous material kuitira kubvisa maomarara akaturikwa ipapo.Kana hukobvu hwesefa yepakati hwakafanana nehukuru hwezvikamu zvichabviswa, maitiro acho anonzi surface filtration, sezvo zvinhu zvakavharirwa pamusoro pesefa.Zvakajairika kuwana mafirita emhepo emhando iyi.
Mumwe muenzaniso wakajairika wekusefa kwepasi is sieves.Muchiitiko ichi, zvimedu zvakavharirwa pamusoro, zvichigadzira keke uye zvichibvumira zviduku zviduku kuti zvipfuure kuburikidza nekusefa network.Kune akawanda mafomati emasefa epamusoro.
Chii chinonzi deep filter?
Mune yakadzika sefa, mukupesana neyepamusoro sefa, zvimedu zvakasimba zvinopatsanurwa zvakanyanya nekuisa mukati me pores yesvikiro yepakati, inogona kuve ne:
1.Mubhedha wezviyo zvakakora (somuenzaniso, 0.3 kusvika 5 mm yakadzika yejecha).
2.Masendimita mashoma emafibers (cartridge filters yakavharwa ne resins, somuenzaniso).
3.Kusiya mashoma mamirimita akakora (somuenzaniso, sefa midhiya yakagadzirwa ne cellulose).
4.A granular support layer kune main filter (pre-coating layer, semuenzaniso).
Nenzira iyi, ukobvu hwesefa yepakati inokwana ka100 yakakura kupfuura saizi yechikamu chinosefa, kana zvasvika pakudzika mafirita.Vanogona kuva waya cartridges, faibha agglomerates, porous epurasitiki uye sintered simbi.Naizvozvo, mafirita akadzika anoumbwa neasina kujairika network yemicrofibers ediki diki granulometry, kusvika pakuchengetedza diki diki.Iyi ficha ndiyo inovimbisa kuti kusefa hakuzongoitika pamusoro, asi nekudzika kuburikidza nesefa midhiya.Izvi, zvakare, zvinogona kuve nemapolymers, cellulose kana fiberglass, yakaparadzaniswa kana kuumbwa.
Saka, mukusefa kwakadzama, zvinosvibisa zvinofamba nemhando ye "labyrinth" mukati memudziyo, zvichipinda mukati meiyo interlaced microfibers inoumba mambure ekusefa.Masefa mazhinji akadzama mapepa akapetwa muhukobvu hwakasiyana, nokudaro achigadzira nzvimbo yakakura yekusefa munzvimbo imwechete, kana ichienzaniswa nemasefa epamusoro akaenzana.
Iyi ndiyo mukana mukuru weyakadzika sefa, sezvo zvichizotora nguva yakareba kuti izere (kuvhara).Mune yakadzika sefa, keke yekusefa inoumbwa, iyo inofanirwa kubviswa nguva nenguva kudzivirira kuvhara, kudonha kana kutadza mukugadzira.Iyo pie ichaumba kusvika sefa yasvika pakuzara.Pane mamwe mafirita mafirita modhi, zvinokwanisika kuchenesa kashoma nemhepo yakamanikidzwa kana mafuta edhiziri usati wada kuachinja zvachose.
Ndeupi musiyano uripo pakati pavo?
Muzviitiko zvese izvi, maitiro emuviri anobatanidzwa ndeaya: kupindira kwakananga, inertial kukanganisa, kupararira uye sedimentation.Musefa yepamusoro, zvisinei, nzira dzekusefa dziri kubonderana kana kusefa.Panyaya yekudzika sefa, iko kupindira.
Kunyangwe mafirita akadzika anogona kugara achitaridzika zvirinani, chiratidzo chekuti ndeipi sefa iri nani pane imwe neimwe.Sezvo iri tekinoroji yepamusoro, kushandiswa kwemafirita akadzika kunonyanya kukurudzirwa mune zvemasisitimu anotarisisa kusvibiswa, senge hydraulic system.
