Musiyano uripo pakati pevhu kusefa uye kwakadzika kusefa

Chinovhara zvinhu zvinonyanya anoshandiswa pamusoro pevhu kusefa uye akanzwa zvinhu zvinoshandiswa pakadzika kusefa. Misiyano inotevera:

1. Iyo yekuvhara screen (nylon monofilament, simbi monofilament) inonongedza zvakananga zvakasviba mune kusefa pamusoro pechinhu. Izvo zvakanakira ndezvekuti monofilament chimiro inogona kucheneswa kakawanda uye mutengo wekushandisa wakaderera; Asi iko kusanzwisisika ndeye pamusoro peiyo filtration modhi, iri nyore kukonzera kumeso kuvharika kweye bhegi resafa. Rudzi rwechigadzirwa urwu rwakanyanya kukodzera panguva dzakakora dzekutsvaira nemhando yepasi, uye chaiyo filtration ndeye 25-1200 μ m.

2.Felt zvinhu (tsono yakarohwa jira, mhinduro yakaputirwa isina-yakarukwa jira) yakajairwa yakadzika-mativi matatu firita yezvinhu, iyo inozivikanwa nekusununguka fiber chimiro uye yakakwira porosity, iyo inowedzera kugona kwehusina tsvina. Rudzi urwu rwefibisi zvinhu ndezvekomboni yekubatira maitiro, ndiko kuti, zvidimbu zvakakura zvezvisina kuchena zvinobatika pamusoro peiyo fiber, nepo zvidimbu zvakanaka zvakabatirwa munzvimbo yakadzika yeiyo firita zvinhu, saka kusefa kune kwakakwirira kusefa mashandiro, Pamusoro pezvo, iyo yepamusoro tembiricha pamusoro pekupisa kurapwa, ndiko kuti, kushandiswa kweiyo pakarepo sintering tekinoroji, inogona kunyatso kudzivirira iyo fiber kubva pakurasikirwa nekuda kweiyo-yekumhanyisa mhedzisiro yemvura panguva yekusefa; Izvo zvinonzwa zvinhu zvinoraswa uye iyo chaiyo filtration ndeye 1-200 μ m.

Huru zvinhu zvemidziyo yefaera yaainzwa ndeinotevera:

Polyester - iyo inowanzo shandiswa firita fiber, yakanaka kemikari kuramba, kushanda tembiricha isingasviki 170-190 ℃

Polypropylene inoshandiswa kusefa kwemvura mumakemikari indasitiri. Iyo ine yakanakisa acid uye alkali kuramba. Kupisa kwayo kwekushanda kuri pasi pe100-110 ℃

Shinda - yakanaka anti solvent basa, asi haina kukodzera anti acid, alkali kusefa

Nilong ine yakanaka kemikari kuramba (kunze kweasidhi kuramba), uye kwaro kushanda tembiricha iri pasi pe170-190 ℃

Fluoride ine yakanakisa mashandiro ekupisa tembiricha uye kemikari kuramba, uye tembiricha yekushanda iri pasi pe250-270 ℃

Kufananidza kwezvakanakira nekuipira pakati pevhu pefa zvinhu uye zvakadzama firita zvinhu

Kune akawanda marudzi eichifa zvinhu zvekusefa. Senge rakarukwa waya pajira riya, firita bepa, simbi jira, sintered firita chinhu uye akanzwa, nezvimwe zvakadaro, zvinoenderana nenzira yayo yekusefa, inogona kuganhurwa mumhando mbiri, kureva pamusoro mhando uye kudzika mhando.

1. Surface firita yezvinhu
Surface mhando firita zvinhu zvinonziwo mhedziso firita zvinhu. Pamusoro paro pane imwe geometry, yunifomu micropores kana migero. Inoshandiswa kubata tsvina mumafuta anovharira. Sefa zvinhu zvinowanzo kuve pachena kana twill firita yakagadzirwa nesimbi waya, machira fiber kana zvimwe zvinhu. Iyo yekusefa musimboti yakafanana nekushandisa kweiyo chaiyo skrini. Kugonesa kwaro kwakaringana kunoenderana neijometri kukura kwe micropores uye chiteshi.

Zvakanakira zvemhando yepasi firita zvinhu: kuratidzwa kwakaringana kweakarurama, hwakawanda hwekushandisa. Nyore kuchenesa, reusable, refu basa upenyu.

Izvo zvakanakira zvepasi mhando firita zvinhu zvinotevera: diki yakasviba; Nekuda kwekukamisirwa kwetekinoroji yekugadzira, iko iko iko kushomeka pane gumi

2. Yakadzika firita zvinhu
Kudzika mhando firita zvinhu inonzi zvakare yakadzika mhando firita zvinhu kana zvemukati mhando firita zvinhu. Iyo firita yezvinhu ine imwe hukobvu, iyo inogona kunzwisiswa sekuwedzeredzwa kweakawanda epamusoro mhando mhando mafirita. Iyo yemukati chiteshi inoumbwa isina yakajairwa uye isina yakatarwa saizi yemvura yakadzika. Mafuta paanopfuura nepasefa yezvinhu, tsvina iri mumafuta inobatwa kana kushambadzirwa munzvimbo dzakadzika dzakasiyana dzefaera zvinhu. Kuti uite basa rekusefa. Sefa bepa rinowanzoitika rakadzika firita zvinhu zvinoshandiswa mu hydraulic system. Kurongeka kwacho kunowanzo pakati pe3 ne20um.

Izvo zvakanakira yakadzama mhando firita zvinhu: hombe huwandu hwetsvina, hupenyu hwakareba hwebasa, inokwanisa kubvisa akawanda masende akapfava pane iwo chaiwo uye bvisa, yakakwira kusefa chaiyo.

Kukanganisika kwekudzika kwerudzi rwefirita yezvinhu: hapana saizi saizi yefaera zvinhu mukaha. Hukuru hwezvinhu zvisina kuchena hazvigone kudzorwa nemazvo; Zvinenge zvisingaite kuchenesa. Mazhinji acho anoraswa. Iko kushandiswa kwakakura.
