Mechanical seals anogona kugadzirisa akasiyana ekuisa chisimbiso matambudziko. Heano mashoma anosimbisa kuchinjika kwemakanika zvisimbiso uye anoratidza kuti nei achikoshera mune yanhasi maindasitiri chikamu.
1. Dry Powder Ribbon Blenders
Matambudziko akati wandei anouya kana uchishandisa hupfu hwakaoma. Chikonzero chikuru ndechekuti kana ukashandisa chisimbiso chinoda mafuta emvura, zvinogona kuita kuti hupfu huvhare kutenderedza nzvimbo yekuisa chisimbiso. Kuvharika uku kunogona kuva nenjodzi kunzira yekuisa chisimbiso. Mhinduro ndeyekubvisa poda pamwe nenitrogen kana mweya wakadzvanywa. Nenzira iyi, hupfu hauzouye mukutamba, uye kuvhara hakufanirwe kuve nyaya.
Kunyangwe iwe ukafunga kushandisa nitrogen kana mhepo yakamanikidzwa, ita shuwa kuti mhepo inoyerera yakachena uye yakavimbika. Kana kudzvinyirirwa kwakadzikira, saka izvi zvinogona kubvumira hupfu kuti hubatane nepacking-shaft interface, iyo inokunda chinangwa chekuyerera kwemhepo.
Kufambira mberi kutsva mukugadzira kwakafukidzwa muna Ndira 2019 chinyorwa chePumps & Systems inogadzira siliconized graphite zvinhu uchishandisa kemikari vapor reaction inoshandura nzvimbo dzakafumurwa dze electrographite kuita silicone carbide. Iyo siliconized nzvimbo inodzivirira zvakanyanya kupfuura simbi, uye maitiro aya anobvumira kuita kuti zvinhu zvive zvakaomarara zvigadziriso sezvo kemikari inoita isingachinji saizi.

Kuti uderedze guruva, shandisa vheji yekuburitsa ine guruva-yakasimba chivharo kuchengetedza gasket cap
Shandisa zvindori zvemwenje pagland yekurongedza uye chengetedza hushoma hwemhepo yekumanikidza panguva yekubatanidza maitiro kuitira kudzivirira zvimedu kubva pakuwana stuffing bhokisi. Izvi zvichadzivirirawo shaft kubva pakupfeka.
2. Inoyangarara Backup Rings yeHigh-Pressure Rotary Seals
Zvindori zvekuchengetedza zvinowanzo shandiswa pamwe chete nezvisimbiso zvekutanga kana O-mhete kubatsira maO-mhete kuramba mhedzisiro yeextrusion. Mhete yekuchengetedza yakanakira kushandisa mune yakakwirira-kumanikidza rotary masisitimu, kana mune zviitiko apo akakosha extrusion gaps aripo.
Nekuda kweiyo yakanyanya kudzvanywa muhurongwa, pane njodzi yekuti shaft isarongeka kana kudzvanywa kwepamusoro kukonzeresa kuti zvinhu zviremara. Nekudaro, kushandisa inoyangarara backup mhete mune yakakwirira-kudzvanywa rotary system imhinduro yakanaka nekuti inoteedzera lateral shaft kufamba, uye zvikamu hazviremara panguva yekushandiswa.

Rimwe rematambudziko makuru ane chekuita nemagetsi zvisimbiso mune aya akanyanya-kudzvanywa masisitimu ndeyekuwana diki diki rinogoneka extrusion gap clearance kuderedza kukuvadzwa kweextrusion. Iyo yakakura iyo gap extrusion, iyo yakanyanya kukuvadza kukuvadza kuchisimbiso kunogona kuve nekufamba kwenguva.
Chimwe chinodiwa ndechekudzivirira simbi-kune-simbi kusangana pane extrusion gap inokonzerwa nekutsauka. Kubata kwakadaro kunogona kukonzera kukweshera kwakaringana kubva mukupisa kuti pakupedzisira kupe simba chisimbiso chemuchina uye kuita kuti isarambe ichidzivirirwa neextrusion.
3. Zvisimbiso zvakamanikidzwa kaviri paLatex
Nhoroondo, iyo inonyanya kunetsa chikamu che mechaniki latex chisimbiso ndechekuti inoomesa kana ichiratidzwa kupisa kana kupokana. Kana latex seal inoratidzwa nekupisa, mvura inovhara kubva kune dzimwe zvidimbu, izvo zvinoita kuti iome. Kana iyo latex yekuisa chisimbiso ichipinda mugomba riri pakati pechisimbiso chechisimbiso kumeso, inoratidzirwa kune friction uye shears. Izvi zvinotungamirira ku coagulation, izvo zvinokanganisa kuiswa chisimbiso.
Kugadzirisa kuri nyore kushandisa kaviri-kudzvanywa mechanical chisimbiso nekuti chinovharira fluid chinogadzirwa mukati. Nekudaro, pane mukana wekuti latex inogona kuramba ichipinda mukati mezvisimbiso nekuda kwekumanikidza kukanganisa. Nzira yechokwadi-yemoto yekugadzirisa dambudziko iri kushandisa kaviri katuriji chisimbiso chine throttle kudzora gwara rekutsvaira.

Ita shuwa kuti pombi yako yakanyatsoenderana. Shaft inopera, kutsauka panguva yekuoma kwekutanga, kana mapombi epombi anogona kurasa kurongeka kwako uye zvinokonzeresa kushushikana pachisimbiso.
Gara uchiverenga zvinyorwa zvinoperekedza zvisimbiso zvako zvemakanika kuti uone kuti unoaisa kekutanga nenzira kwayo; kana zvisina kudaro, coagulation inogona kuitika nyore uye kukanganisa maitiro ako. Zviri nyore kupfuura vamwe vanhu vanotarisira kuita zvikanganiso zviduku zvinogona kukanganisa kushanda kwechisimbiso uye kukonzera migumisiro isingatarisirwi.
Kudzora firimu remvura rinosangana nechiso chechisimbiso rinowedzera hupenyu hwechisimbiso chemuchina, uye zvisimbiso zvakapetwa kaviri zvinopa kutonga ikoko.
Gara uchiisa chisimbiso chako chakapetwa kaviri nekudzora kwezvakatipoteredza kana tsigiro sisitimu yekuunza mvura inovharira pakati pezvisimbiso zviviri. Mvura yacho inowanzobva mutangi kuzozora zvisimbiso kuburikidza nechirongwa chepombi. Shandisa nhanho uye kumanikidza mita patangi kuti ushande zvakachengeteka uye kutakura kwakaringana.
4. Specialized E-Axle Seals yeMagetsi Mota
Iyo e-axle pamotokari yemagetsi inoita mabasa akabatanidzwa einjini uye kutapurirana. Imwe yezvinetso mukusunga gadziriro iyi ndeyokuti motokari dzemagetsi dzinofambiswa nemotokari dzinomhanya zvakapetwa kasere kupfuura dziri pamotokari dzine simba regesi, uye kumhanya kungangowedzera zvakanyanya sezvo motokari dzemagetsi dzinowedzera.
Zvisimbiso zvechinyakare zvinoshandiswa kuma e-axles zvine miganho yekutenderera inosvika 100 tsoka pasekondi. Kuteedzera ikoko kunoreva kuti mota dzemagetsi dzinongokwanisa kufamba nzendo pfupi pamutengo mumwe chete. Zvisinei, chisimbiso chichangobva kugadzirwa chakagadzirwa kubva ku polytetrafluoroethylene (PTFE) chakabudirira kubata 500-awa accelerated load cycle test iyo yakatevedzera mamiriro chaiwo ekufambisa kwepasi uye yakakwanisa kutenderera kukurumidza kwemamita 130 pasekondi. Zvisimbiso zvakaiswa kuburikidza ne5,000 maawa ekutsungirira kuyedzwa, zvakare.
Kunyatsoongorora zvisimbiso mushure mekuyedzwa kwakaratidza kuti pakanga pasina kubuda kana kusakara pashaft kana muromo wekusimbisa. Uyezve, kupfeka pamusoro pekumhanya kwaisaonekwa.

Zvisimbiso zvinotaurwa pano zvichiri muchikamu chekuedza uye hazvisati zvagadzirira kuparadzirwa kwakapararira. Nekudaro, kubatana kwakananga kwemota uye giya bhokisi kunopa matambudziko ane chekuita nemagetsi zvisimbiso kune ese emagetsi mota.
Kunyanya, mota inofanirwa kuramba yakaoma nepo giya bhokisi richigara rakazorwa. Mamiriro ezvinhu aya anoita kuti zvive zvakakosha kuwana chisimbiso chakavimbika. Pamusoro pezvo, vanoisa vanofanira kuvavarira kusarudza chisimbiso chinoita kuti e-axle ifambe ichitenderera inodarika zana nemakumi matatu kutenderera paminiti - iyo yazvino indasitiri yekuda - uku ichideredza kupokana.
Mechanical Seals: Yakakosha paKushanda Kwakafanana
Iyo yekutarisisa pano inoratidza kuti kutora iyo chaiyo mechaniki chisimbiso chechinangwa inopesvedzera mhedzisiro. Uyezve, kujairana neakanakisa maitiro ekuisa kunobatsira vanhu kudzivirira misungo.
