Pandinoona amechanical sealmukuita, ndinonzwa kufemerwa nesainzi iri shure kwayo. Mudziyo muduku uyu unochengeta mvura mukati memudziyo, kunyange kana zvikamu zvinofamba nekukurumidza.
- Mainjiniya vanoshandisa maturusi akadaiCFD uye FEAkudzidza mazinga ekudonha, kushushikana, uye kuvimbika.
- Nyanzvi dzinoyerawofriction torque uye leakage rateskuve nechokwadi kuti chisimbiso chega chega chinoshanda zvakanyanya.
Key Takeaways
- Mechanical sealsgadzira chivharo chakasimba chinomisa kudonha mumapombi nemichina, kunyangwe kana zvikamu zvinofamba nekukurumidza, kudzivirira michina uye nharaunda.
- Kusarudza zvinhu zvakakodzera uye rudzi rwechisimbiso kunobatsira zvisimbiso kugara kwenguva refu, kuderedza kushandiswa kwesimba, uye kuderedza mari yekugadzirisa.
- Kugara uchiongorora uye nekuchengetedza kwakaringana chengetedza michina zvisimbiso kushanda zvakanaka, kuchengetedza mari uye kudzivirira kuparara.
Iyo Mechanical Chisimbiso Inoshanda
Kushanda Nheyo yeMechanical Chisimbiso
Pandinotarisa amechanical seal, ndinoona mhinduro yakangwara yedambudziko rakaoma. Chisimbiso chinogadzira kubatana kwakasimba pakati peshaft inofamba uye imba yakamira. Iyi interface inochengeta mvura mukati mepombi, musanganiswa, kana compressor, kunyangwe shaft ichitenderera nekumhanya kwakanyanya. Ndinoona zvichishamisa kuti sainzi neinjiniya zvinosangana sei pano.
Masayendisiti anoshandisa mhando dzemakombuta kudzidza mafambiro emvura uye kuti kupisa kunopararira sei mukati mechisimbiso. Vanoshandisa equations kufanotaura kuti chisimbiso chichaita sei kune shanduko mukumanikidza, kumhanya, kana tembiricha. Semuyenzaniso, kana simba rinodzvanya chisimbiso rakatarisana pamwechete richichinja ne4% chete, chiso chisimbiso chinogona kufamba kupfuura 34% yakawanda, uye kuvuza kunogona kusvetuka neinopfuura 100%. Nhamba idzi dzinoratidza kuti chisimbiso chinokanganisa sei nharaunda yacho. Mainjiniya anoedza mamodheru avo nezviyedzo zvehupenyu chaihwo, kuyera tembiricha uye kudonha kwemazinga. Themhedzisiro inowirirana zvakanyanya, zvichiratidza kuti sayenzi shure kwechisimbiso inoshanda munyika chaiyo.
Zvikamu Zvikuru zveMechanical Chisimbiso
Ndinogara ndichinzwa kufadzwa nezvikamu zvinoumba mechanical seal. Chikamu chega chega chine basa rakakosha, uye pamwe chete vanogadzira chipingamupinyi chakasimba kurwisa kubuda.
- Kutenderera Chisimbiso Chiso: Chikamu ichi chinotenderera ne shaft. Inofanira kugara yakapfava uye yakapfava.
- Stationary Chisimbiso Chiso: Chikamu ichi chinoramba chakamira, chakatsikirirwa pachiso chinotenderera.
- Sekondari Zvisimbiso: O-mhete kana elastomers anozadza chero madiki madiki uye chengeta chisimbiso chakasimba.
- Spring kana Bellows: Izvi zvinosundidzira zviso zvechisimbiso pamwechete, kunyangwe shaft ikafamba zvishoma.
- Metal Zvikamu: Aya anobata zvese munzvimbo uye anobatsira chisimbiso kuti chikwane midziyo.
Kusarudza zvinhu kunokosha zvikuru. ndaona zvisimbiso zvinogadzirwa kubva kumakeramiki kana carbides zvinogara kwenguva refukupfuura magadzirirwo ekare. Zvinhu izvi zvinoramba kupfeka uye kupisa. O-mhete uye mafuta anokosha anobatsira chisimbiso kushanda zvakanaka kwemakore. Mainjiniya vanogadzira zviso kuti zvive zvakati sandara uye zvakafanana. Iyi dhizaini yekuchenjerera inochengetedza inodonha kusvika kushoma uye inobatsira chisimbiso kugara kwenguva refu.
Zano:Paunosarudza chisimbiso chemagetsi, nguva dzose chengetedza zvinhu. Simbi isina tsvina inoshanda zvakanaka pakupisa kukuru. PTFE inomira kune yakaoma makemikari.
Maitiro eMechanical Seals Anodzivirira Kudonha
Ndinotenda kuti mashiripiti chaiwo echisimbiso chemuchina anoitika pakamuka kadiki pakati pezviso zviviri zvechisimbiso. Firimu rakatetepa remhando dzemvura pano. Iyi firimu inoita senge cushion, inoderedza kukakavara uye kupfeka. Kana iyo firimu yakanyanya kukora, kudonha kunogona kuitika. Kana yakanyanya kutetepa, zviso zvinogona kupera nekukurumidza. Mainjiniya vanodzidza kuti zviso zvakakasharara kana kutsvedzerera sei, uye kuti kupisa kunochinja sei gaka. Vanoshandisa grooves yakakosha uye mapatani kudzora firimu remvura.
Bvunzo mumafekitari dzinoratidza kuti zvisimbiso zvitsva zvinoramba zvichidonha zvakaderera, kunyangwe pasi pekumanikidzwa kwakanyanya. Pashure pezviuru zvemaawa,zvisimbiso zvakasakara zvinogona kutanga kudonha zvakanyanya, kunyanya kana nzvimbo yacho ikakuvara. Ndakaona kuti kuchengeta zviso zvechisimbiso zvakachena uye zvakatsetseka zvinoita mutsauko mukuru.
Mune zvimwe zviitiko, zvisimbiso zvinobvumira chete huwandu hushoma hwemhute kubuda—inenge 1 cc pazuva. Izvi zvakachengeteka kumvura zhinji. Kune makemikari ane njodzi, madhizaini akasarudzika anoita kuti mvura inodonha isvike zero.
Ini ndinonzwa kudada kuziva kuti michina zvisimbiso zvinodzivirira vanhu uye nharaunda nekumisa kudonha mumamiriro ezvinhu akaoma.
Mhando, Kuenzanisa, uye Mabhenefiti eMechanical Seals
Mhando dzeMechanical Seals uye Typical Applications
Ini ndinoona akawanda marudzi emakanika zvisimbiso mubasa rangu. Mhando imwe neimwe inokodzera basa rinokosha. Cartridge seals anouya akagadzirira kuisa, zvichiita kuti kuseta kuve nyore. Pusher zvisimbiso zvinoshandisa zvitubu kuchengetedza zviso zvechisimbiso pamwechete. Non-pusher seals kushandiswamupfumvutira panzvimbo yamatsime. Ini ndinowanzo shandisa zvisimbiso zvakapetwa kumvura ine njodzi nekuti inowedzera dziviriro. Split seals inobatsira pandisingakwanise kupatsanura michina. Ini ndinosarudza chisimbiso chakakodzera zvichibva pamvura, kudzvanywa, uye kumhanya. Semuenzaniso, ndinoshandisa zvisimbiso zvimwechete mumapombi emvura yakachena uye zvisimbiso zviviri mumiti yemakemikari.
Mechanical Seal vs. Packing uye Zvimwe Zvimwe
Pandinofananidza chisimbiso chemuchina nekurongedza gland, ndinoona misiyano mikuru. Kurongedza kunoda kusimbiswa nguva nenguva uye kunodonha zvakanyanya. Mechanical seals anoramba achidonha akadzikira uye anochengetedza simba. Ndakagadzira tafura kuratidza misiyano mikuru:
| Aspect | Mechanical Seals | Gland Packing |
|---|---|---|
| Leakage Rate | Zvinonyanya kuderera;leakage ratio ye1 | Much higher; leakage ratio ye800 |
| Kushandisa Simba | Zvinenge 50% zvishoma pane kurongedza | Kushandiswa kwesimba kwepamusoro |
| Zvido Zvekushanda | Inoda kugezeswa pakutonhodza nekuchenesa | Inoda kuchengetedzwa nguva nenguva |
| Maintenance Issues | Sensitive kuoma kumhanya uye misalignment | Inowanzoita abrasion uye kuvuza |
Tafura iyi inondikurudzira kuti ndisarudze yakanakisa sarudzo yebasa rega rega.
Mabhenefiti Akakosha Ekushandisa Mechanical Seals
Ndinonzwa kudada pandinoshandisa chisimbiso chemuchina nekuti chinodzivirira midziyo uye nharaunda. Inoderedza kudonha, inochengetedza simba, uye inoderedza mari yekugadzirisa. Ndiri kuona hupenyu hurefu hwemidziyo uye kushomeka kushoma. Nechisimbiso chakakodzera, ini ndinobatsira timu yangu kushanda zvakachengeteka uye nemazvo.
Zano:Kusarudza chisimbiso chakanaka kunogona kutungamirira kumakore ekushanda kusina matambudziko.
Ndinovimba nechisimbiso chemuchina kuchengetedza midziyo yangu ichishanda yakasimba. Ndinoona mhedzisiro chaiyo: mapombi anogara makore matatu kureba, uye ini ndinochengeta kusvika ku50% pakugadzirisa. Hezvino zvandinoona:
| Benefit | Real-World Result |
|---|---|
| Kuchengetedza Simba | 5-10% shoma simba rinoshandiswa |
| Lower Costs | $500,000 yakachengetwa pane saiti |
FAQ
Chii chandinofanira kuita kana chisimbiso changu chikatanga kubuda?
Ndinogara ndichitarisa tsvina kana kukanganisa kutanga. Kuchenesa chisimbiso kana kutsiva zvikamu zvakasakara zvinowanzogadzirisa dambudziko.
Zano:Macheki enguva dzose anoita kuti midziyo yangu ishande yakasimba.
Iyo mechanical seal inowanzogara kwenguva yakareba sei?
Ini ndinoona zvisimbiso zvakawanda zvinogara kubva kune rimwe kusvika kumakore mashanu. Kutarisirwa kwakanaka uye zvinhu zvakafanira zvinondibatsira kusvika pahupenyu hwakareba kwazvo.
Ndinokwanisa kuisa chisimbiso chemuchina ndega here?
Ndinotenda kuti chero munhu anogona kudzidza hunyanzvi uhu. Ini ndinotevera mirairo nhanho nhanho.
- Ndinoshandisa maturusi akakodzera.
