How To Sarudza The rakavhara Method In The machine Design?

1.Kutakura Chisimbiso

Zvinoenderana nehunhu hwayo, kurongedza zvisimbiso kunogona kukamurwa kuve:

• Yakapfava kurongedza chisimbiso
• Yakaoma kurongedza chisimbiso
• Yakagadzirwa kurongedza chisimbiso

A. Chinyoro chekutakura chisimbiso

Runyoro kurongedza mhando: kurongedza

Kurongedza kunowanzo kuvezwa kubva kune dzakapfava tambo uye kuzadzwa mune yakavharika mhango nematanda ane mativi akaenzana-chikamu chikamu. Simba rekutsikirira rinogadzirwa negland kumanikidza kurongedza uye kumanikidza kurongedza kuti kumanikidzwa pane yekuisa chisimbiso pamusoro (mugodhi). Pamusoro pekunze uye iyo yakavharika mhango), iro radial simba reiyo yekumisikidza mhedzisiro inogadzirwa, nokudaro ichitamba basa rekuisa chisimbiso.

Zvinoshanda nguva dzekupfava kurongedza:

Iko kurongedza zvinhu zvakasarudzirwa kurongedza zvinoisa chisimbiso mhedzisiro yekutakura. Kazhinji kutaura, iko kurongedza zvinhu kunogumirwa netembiricha, kumanikidza uye pH yeanoshanda svikiro, uye kumeso kusagadzikana uye eccentricity yemuchina michina iko iko kurongedza kunoshanda Uye kumhanyisa kumhanya, nezvimwewo, zvichave zvakare nezvinodiwa pasarudzo kurongedza zvinhu. Graphite kurongedza inogona kumira yakanyanya tembiricha uye yakanyanya kumanikidza, uye ndechimwe chezvinhu zvinoshanda zvigadzirwa kugadzirisa dambudziko repamusoro tembiricha uye yakanyanya kumanikidza chisimbiso Ngura kuramba, yakanakisa yekuisa chisimbiso kuita, yakagadzikana uye yakavimbika basa. Aramid kurongedza imhando yepamusoro-simba organic organic. Kurongedza kwakarukwa kunoiswa mudumbu ne polytetrafluoroethylene emulsion uye mafuta. Polytetrafluoroethylene kurongedza kunoitwa kwakachena polytetrafluoroethylene kupararira nebwe sechinhu chisina kugadzirwa zvinhu, kutanga kugadzirwa mbishi firimu, uyezve yakamonana, yakarukwa uye yakarukwa kuita kurongedza. Inogona kushandiswa zvakanyanya muchikafu, mishonga, kugadzira mapepa, makemikari faibha, nezvimwe zvinodiwa nehutsanana, uye vharafus uye mapombi ane akasimba anoparadza midhiya.

B. Chakaoma kurongedza chisimbiso

Kune mhando mbiri dzezvipupuriro zvakaomarara: mhete yakakamurwa uye mhete yakatsemurwa.

2.Mechaniki Kugadziridza Seal

Iyo michina chisimbiso inogara ichiumbwa nezvikamu zviviri, chinotenderera chikamu (yeyero chikamu) uye chakamira chikamu (orenji chikamu). Idzo mbiri hama dzinofamba uye dzinomira mhete nzvimbo dzinova huru yekuisa chisimbiso pamusoro pechisimbiso.

Mechanical zvisimbiso zvinodaidzwa kunzi kumagumo kumeso zvisimbiso. Zvinoenderana nematanho akakosha emunyika, ivo vanotsanangurwa sekuti: angangoita maviri ekupedzisira anotarisana akatarisa kune axis yekutenderera anochengetwa padhuze nekubatana uye kutsvedza hama kune mumwe nemumwe pasi pekushandira pamwe kwemvura inomanikidza uye neelastic simba (kana simba remagineti) yenzira yekubhadhara uye chisimbiso chebetsero. Yakagadzirwa kudzivirira kuyerera kwemvura.

3.Dry Gasi Seal

Yakaomeswa gasi chisimbiso, kana "yakaoma inomhanya gasi chisimbiso", iri mhando nyowani yemugodhi yekupedzisira chisimbiso inoshandisa slotted yekuisa tekinoroji yekuisa chisimbiso gasi, uye isiri-yekudyidzana chisimbiso.

Features:

Kuiswa chisimbiso kwakanaka, hupenyu hurefu, hapana chikonzero chekuvhara mafuta system, yakaderera simba rekushandisa, mashandiro mashoma uye yakaderera mashandiro uye mari yekuchengetedza. Segadziriro-yemahara yekuisa chisimbiso sisitimu iyo isingade chero yekuisa chisimbiso kumagumo kumeso kutonhora uye mafuta ekuzora, yakaoma gasi zvisimbiso zviri kutsiva zvinoyangarara zvindori zvisimbiso uye labyrinth zvisimbiso kuva chisimbiso chikuru cheiyo shaft chisimbiso cheiyo-inomhanya centrifugal compressors mune petrochemical indasitiri .

Applications:

Yakakwira-inomhanya fluid michina senge centrifugal compressors inokodzera mashandiro ezvinhu apo shoma gadziriro gasi inodonhedza mumhepo isina kukuvara, senge mweya compressors, nitrogen compressors, nezvimwe.

4. Chisimbiso cheLabyrinth

Iyo labyrinth chisimbiso ndeyekuisa akati wandei wedenderedzwa yekuisa mazino akarongedzwa mukuteedzana kutenderera iyo inotenderera shaft. Akateedzana ematanho ekuvharira uye maburi ekuwedzera anoumbwa pakati pemeno nemeno. Kana svikiro rakavharwa richipfuura nepakati peiyo labourinth inotyisa, inoburitsa hunhu hwekudzivirira kuputika.

Labyrinth chisimbiso ndiyo inonyanya kukosha yekuisa chisimbiso fomu pakati pematanho uye shaft magumo ecentrifugal compressors. Zvinoenderana neakasiyana maitiro, inogona kuganhurwa mumhando ina: akatsetseka, zigzag, akatsika uye huchi.

A. Smooth labyrinth chisimbiso

Iyo yakatsetseka labyrinth chisimbiso ine zvivakwa zviviri: inosangana uye yekuisa. Iyo ine yakapusa chimiro uye iri nyore kugadzira, asi iyo yekuisa mucherechedzo murombo.

B. Zigzag labyrinth chisimbiso

Iyo zigzag labyrinth chisimbiso zvakare chakakamurwa muzvimiro zviviri: iyo yakazara uye yekuisa. Chimiro chechimiro chechisimbiso ichi cheyabrinth ndechekuti iko kukwira kwemazino ekuisa chisimbiso kwakasiyana, uye mazino epamusoro uye akaderera akarongedzwa neimwe nzira, uye inoenderana shaft yepamusoro yakakosha concave-convex groove Groove, chimiro cheakakwirira uye akaderera mazino akafananidzwa neiyo concave-convex groove inoita kuti mitezo yekuisa chisviniro ive yerudzi rwezagzag, nekudaro, kuyerera kwekurwisa kunowedzerwa uye kugona kwekuisa chisimbiso kunovandudzwa. Asi inogona chete kushandiswa mumasirinda kana zvikamu zvine yakatsemuka nzvimbo, uye iyo yekuisa chisimbiso muviri inofanirawo kuitwa yakatwasuka yakatsemurwa mhando.

C. Akapfuura labyrinth chisimbiso

Kubva pakuongorora kwechimiro, iyo yakadonha labyrinth chisimbiso chakafanana neyakareruka labyrinth chisimbiso, asi iyo yekuisa mucherechedzo yakafanana neiyo zigzag labyrinth chisimbiso, uye inowanzo shandiswa mune yekumanikidza chifukidzo uye bhalansi disc.

D. Honeycomb labyrinth chisimbiso

Mazino ekuisa chisimbiso echisviniro chehuchi hwenyuchi chakasunganidzwa kuita huchi hwehuchi kuita kamuri yekuwedzera yakaoma kuumbwa. Kuiswa chisimbiso kwaro kuri nani pane iyo yekuisa chisimbiso fomu, uye inokodzera zviitiko zvine hombe kumanikidza misiyano, senge bhalansi disc chisimbiso checentrifugal compressor. Iyo honeycomb labyrinth chisimbiso ine yakaoma nzira yekugadzira, yakasimba simba yekuisa chisimbiso jira, uye yakanaka yekuisa chisimbiso mhedzisiro.

5.Chisimbiso cheOiri

Iyo mafuta chisimbiso chisimbiso ndeye-yekuzvisimbisa-wega chisimbiso chemuromo ine yakapusa dhizaini, diki saizi, yakaderera mutengo, iri nyore kugadzirisa, uye yakaderera kuramba torque. Izvo hazvigone chete kudzivirira kuvuza kwepakati, asi zvakare kudzivirira kupindira kweguruva rekunze uye zvimwe zvinokuvadza zvinhu. Iko kune imwe nhanho yemubhadharo wekupfeka, asi haina kupokana neyakaomesesa, saka inowanzo shandiswa pamakemikari mapombi mune yakaderera nguva yekumanikidza.

6.Simba Seal

Kana pombi yemakemikari iri kushanda, musoro wekumanikidza unoburitswa nemupepeti wemubatsiro inoenzanisira yakanyanya-kumanikidza mvura panzvimbo yekubuda huru, nekudaro ichiwana kuiswa chisimbiso. Paunenge uchipaka, iyo yekubatsira impeller haishande, saka inofanirwa kuve yakagadzirirwa necheni yekupaka chisimbiso kugadzirisa iyo kemikari pombi inodonha inogona kuitika panguva yekupaka. Iyo yekubatsira impeller ine yakapusa yekuisa chisimbiso mamiriro, yakavimbika chisimbiso uye hwakareba hupenyu hwebasa. Iyo kemikari pombi inogona kuwana yekudonha-chiratidzo chemvura panguva yekushanda, saka inowanzo shandiswa mumakemikari mapombi anotakura kusachena midhiya.

7.Spiral Chisimbiso

Spiral chisimbiso zvakare chimiro chesimba rinosimbisa. Iyo inonoka groove inogadzirwa pane inotenderera shaft kana ruoko rweiyo shaft, uye chisimbiso svikiro rinozadzwa pakati pemubato uye ruoko. Iko kutenderera kweiyo shaft kunokonzera iyo inonamira groove kuburitsa irikuendesa mhedzisiro yakafanana neiyo yepombi, nokudaro ichidzivirira kuvuza kweiyo yekuvhara mvura. Iyo saizi yekugona kwayo kwekuisa mucherechedzo inoenderana neiyo helix kona, kukanda, kukwirira kwezino, kukwirira kwezino, kureba kunoshanda kwezino uye saizi yegwanza pakati pemubato nesleeve. Sezvo pasina kukakavadzana pakati pezvisimbiso, hupenyu hwebasa hwakareba, asi nekuda kwekukamurwa kwenzvimbo yemahara, kureba kwekutenderera kazhinji kunopfupika, saka kugona kwayo kwekusimbisa kunogumirawo. Kana iyo pombi ichishandiswa pakuderedzwa kumhanya, iyo yekuisa chisimbiso mhedzisiro inoderedzwa zvakanyanya.

Batanidza kuchinyorwa ichi: Maitiro Ekusarudza Iyo Simbiso Nzira Mune Iyo Machining Dhizaini

Dzokorora Chirevo: Kana pasina mirairo yakakosha, zvinyorwa zvese zviri pasaiti ino ndezvepakutanga. Ndokumbira uratidze kwakabva kudhindazve: https://www.cncmachiningptj.com/, thanks!
