Sezvo anobudirira filtration unosvikirwa, Sefa bepa rave richishandiswa nevakawanda muminda siyana. Maererano mhando fibers anoumba Sefa bepa, chokupika uye kushandiswa Sefa bepa ndiwo akasiyana. Rinogona kushandiswa zvakajairika Sefa bepa kungopa zviitiko, girazi internet Sefa bepa kuti mukuru tembiricha, uye polypropylene Sefa bepa kuti Ultra-yakachena.
Sechivako Sefa bepa iri labyrinth marongerwo rinoumbwa fibers uye migero, izvo pamwe kwomuviri mauto chokuita mvura zvinoumba mupise mashandiro firita mapepa. The filtration mashandiro ari sezvinotevera:
1. Direct kubatwa kana kuvhura
In iyi, vamwe vanhu vakarasika vanodavira kuti ndiyo chete chinoita Anoumba filtration, uye kuti tsvina inoramba vari akarwiswa mune inflow pamusoro kana labyrinth chete nokuti akakura kupfuura aperture. Kutaura zvazviri, pane:
2. Adsorption
Apo yakasvinwa mvura inopfuura nomunyika labyrinth, zvimwe zvacho zviri adsorbed kuti Sefa bepa pasi zvinoitwa electrostatic okutorwa, kunyange dhayamita vamwe nezvimedu iduku zvikuru pane aperture. Naizvozvo, vamwe Sefa zvokuvakisa zvikurukuru kuitwa kunofambira mberi magetsi munguva mukugadzira rikurumidze.
3. rova uye kuwa
In iyi, nokuda ukama pakati aibuda zvazvingava, inoramba vakavharirwa zvakananga pamusoro pemvura Sefa bepa faibha pane pore iri Sefa bepa, uye adsorptive simba uye mvura iyerere simba vari zvinochengetwa payo, nokudaro ichivharira zvimwe zvacho duku.
4. Filtration uye agglomeration
Tiine chichiitwa kuunganidza tsvina inoramba pamusoro pemvura Sefa bepa, anoumba rimwe Sefa rukoko pacharo, iro misungo nezvimedu madiki ari pores pakati guru inoramba. With zvibereko zvacho, ari kurwisa kunowedzera nguva dzose, kusvikira pakupedzisira makavhara zvachose kana asvika differential kufurirwa.
Kugadzirwa Sefa bepa iri nyore chaizvo. Inongova kuti siyana fibers inenge iri mvura-kwakavakirwa binders kuti kwadziri chose, uye ipapo vanoumba zvakasimba waakaita kubatana bepa mupumburu uri sirika chidzitiro. Kuburikidza nokuomesa, kutiva uye nokuomesa, inogamuchirika mwando pamwero kunokwanisika. Asi chokwadi, kugadzirwa zvakanaka Sefa bepa, anochengeta chete kuita pakati batch mangé uye batch mangé, mupumburu rwakapetwa, kunyange pakati makore nemakore, zvinoda kwayo uremu, porosity, permeability, simba uye vamwe kuchinja rakamanikana siyana.
The Sefa Mashoko ari Sefa vanofanira kudzivisa Sefa maitiro rurege damage hunokuvadza nezvimedu, uye panguva imwecheteyo kubvumira Urume yakakwana ichipfuura, kuitira kudzivisa cavitation ari pombi, basa humburumbira uye combustion yomukati. In Nemuromo, mumwe Sefa akakwana zvinofanira kubvisa 100% of utachiona nezvimedu uye zvinopa kupindirana mhepo permeability. Asi chokwadi, izvi hazvibviri.
The namaapuro Sefa bepa anofanira kuita zvose yokufudza zviratidzo zvakasiyana-siyana kuitira kuti adzivirire zvinobudirira negadziriro kuti yakasvinwa zvakanaka. Oil filters dzine zvinodiwa kuti Sefa bepa pane mhepo filters, kunyanya nokuti wevasungwa mafuta anochinja harina pasi zvikuru tembiricha kuchinja, izvo huchachinja filtration chokubuda mafuta.
