1. Tsanangudzo uye Nheyo dzeUnyanzvi dzeHigh-Speed ​​​​Rotary Unions

Mubatanidzwa wemagetsi unotenderera nekukurumidza isangano remagetsi rinotenderera nekuvharira rine michina yakanyatsogadzirwa, iro basa guru nderekuita kuti media (mvura, gasi, utsi, nezvimwewo) isaburitse mvura (mvura, gasi, nezvimwewo) pakati pemidziyo inotenderera (rotor) nemapaipi akagadziriswa (stator). Chinhu chikuru chakanakira hunyanzvi hwayo chiri mukugadzikana kwemuchina uye kuvimbika kwemuchina unotenderera zvichienderana nemamiriro ekushanda anomhanyisa. Zvichienzaniswa nemayuniyoni akajairwa emagetsi, mayuniyoni anotenderera anotenderera nekukurumidza akagadziriswa kuti agadzirise mamiriro ekumhanya kukuru, kazhinji achichinjika kumhando yekumhanya ye3000-15000r/min, uye anogona kuita kuti ashande nekukurumidza kupfuura 20000r/min kuburikidza nekugadzira kwakakosha (senge dynamic balance optimization uye kushandiswa kwezvinhu zvakareruka).

Musimboti wayo mukuru wekushanda unoenderana nekushanda pamwe chete kwesystem yekubata nemazvo uye chimiro chekubatanidza chisimbiso: mabearings ekugadzirisa (akawanda mabearings ekubata mabhora ane kumhanya kwakanyanya kana mabearings eceramic rolling) ane basa rekutsigira rotating shaft system, kuona kuti coaxiality uye kushanda zvakanaka pakumhanya kwakanyanya, uye kudzora radial runout ≤ 0.02mm; chimiro chekubatanidza chisimbiso (kunyanya graphite-silicon carbide mechanical seal, pamwe chete nepolytetrafluoroethylene assixival seals) chinoumba stable sealing interface pakati penzvimbo inotenderera nenzvimbo isingachinji kuburikidza nepreset sealing specific pressure, zvinobudirira kudzivirira kubuda kwemedia, ukuwo zvichideredza kurasikirwa kwekukweshana kwenzvimbo yekuisa chisimbiso uye kuona kugadzikana kwenguva refu pakushanda kwepamusoro.

2. Nzvimbo dzeKushandisa Zvikuru uye Zvinodiwa zveUnyanzvi zveMasangano Ekufamba Nekukurumidza

Mayuniyoni anotenderera anomhanya zvakanyanya anoshandiswa zvakanyanya muminda yemidziyo yepamusoro ine zvinodiwa zvakanyanya pakumhanya, kushanda kwekuvhara uye kuchena kwepakati. Mamiriro akasiyana ekushandisa anoenderana nehunyanzvi hwakajeka.

2.1 Nzvimbo Yokugadzirisa Zvishandiso Zvemuchina

Inonyanya kushandiswa kune masisitimu espindle enzvimbo dzemachining dzinomhanya zvakanyanya uye maCNC lathes. Basa rayo guru nderekuendesa mvura inotonhorera (senge emulsion, oiri yekucheka) kana mweya wakamanikidzwa kune spindle inotenderera nekukurumidza uye maturusi, zvichiita kuti maturusi atonhodze, kubvisa chips uye lubrication yespindle ishande. Izvi zvinoda kuti rotary union ienderane nekumhanya kwe8000-12000r/min, nekubuda kwechisimbiso ≤ 0.1cc/h, uye inofanirwa kuve nekudzivirira ngura yemvura inocheka uye kudzivirira kuzununguka kuitira kuti runout yespindle isakanganise kunyatsoita machining.

2.2 Munda weMichina yeKurongedza

Yakagadzirirwa mitsetse yekuzadza inomhanya zvikuru uye michina yekurongedza inotenderera, inoshandiswa kutakura zvinhu zvine mvura panguva imwe chete (senge zvinwiwa, masosi) kana pneumatic media, ichivimbisa kuenderera mberi uye kugadzikana kwemaitiro ekurongedza. Rotary union inofanirwa kuve nekumhanya kwe3000-6000r/min, chimiro chekuvhara chisina angle kuti isasvibiswe nepakati, uye panguva imwe chete ichichinjika kune zvinhu zvekuvharira zvekudya (senge fluororubber yemhando yechikafu), ichitevedzera mitemo yehutsanana yemichina yechikafu.

2.3 Nzvimbo yeMidziyo yeMagetsi eMhepo

     Inoshandiswa kune sisitimu yekudzora gomba remagetsi emhepo, ine basa rekutumira mafuta ehydraulic kana grisi, kudzora kugadzirisa kona yebanga, uye kuona kuti unit inoshanda zvakatsiga pasi pemhepo yakasiyana. Izvi zvinoda kuti rotary union ienderane nekumhanya kwe5000-8000r/min, irambe ichidzivirira kupisa kwakanyanya uye kwakaderera (-40℃ ~ + 80℃) uye irambe ichidzivirira jecha, chimiro chekuvharira chinofanira kutsungirira kumanikidzwa kwakanyanya (≤10MPa), uye igare ichidzivirira kwenguva refu kuti ideredze nguva yekushanda nekugadzirisa.

2.4 Munda weKugadzira Semiconductor

Inoshandiswa mukugadzira wafer, kuisa firimu rakatetepa uye mimwe michina. Basa rayo guru nderekupa michina yakachena kwazvo (senge mvura yakachena kwazvo, magasi akakosha). Rotary union inofanirwa kuve nekumhanya kwe6000-15000r/min, nzvimbo yekuvhara inoshandisa dhizaini isina zvimedu, chiyero chehutsanana hwepakati chinosvika kuClass 10 kudzivirira tsvina kuti isasvibise wafer, uye inewo ngura inodzivirira kuti ienderane nezvinodiwa zvemagasi akakosha (senge hydrogen fluoride, ammonia).

3. Maitiro Ekuwedzera Hupenyu hweBasa uye Maitiro Ekuchengetedza eMasangano Ekufamba Nekukurumidza

Hupenyu hwebasa rema "high-speed rotary unions" hunonyanya kuenderana nekusakara kwe "sealing surface", kurasikirwa nema "bearing" uye kunyatsorongeka kwekuisa. Pamwe chete nehunhu hwayo hwekushanda, zvakakosha kutevedzera zvakasimba misimboti mitatu mikuru yekuchengetedza ye "kuchena, mafuta uye kurongeka". Magadzirirwo chaiwo ndeaya anotevera:

3.1 Kudzora Kuchena Kwepakati Nepakati

Kuchena kwepakati nepakati ndiko kunokosha pakuona kuti nzvimbo yekuvharira inoramba iripo. Sefa chaiyo (kupfava kwe ≤5μm) inofanira kuiswa kumberi kwepombi yekufambisa yepakati kudzivirira zvidimbu zvakasimba netsvina kupinda muchikamu chekuvharira, zvichikonzera kukwenya nekupfekwa panzvimbo yekuvharira; kuchenesa nguva dzose nzira yekuyerera kwemukati memubato werotary union kudzivirira kukora kwepakati nekukura. Kunyanya kune michina inopisa zvakanyanya (senge mafuta ekufambisa kupisa), zvakakosha kuti ugare uchiona kusviba kwepakati nepakati uye kusvibiswa, uye kutsiva nzvimbo yakashata nenguva. Panguva imwe chete, dzivisa kuisa jointi muguruva nenzvimbo dzinopisa dzegasi, uye isa chifukidziro chekudzivirira kana zvichidikanwa.

3.2 Kugadziriswa kweMafuta eSainzi

Sarudza mafuta chaiwo (akadai semafuta anomhanya zvakanyanya uye anodziya zvakanyanya, tembiricha yakakodzera -20℃ ~ + 150℃) zvichienderana nemamiriro ekushanda, uye wedzera kana kutsiva nguva nenguva. Kutenderera kwekutsiva kunogadziriswa zvichienderana nekumhanya nemamiriro ekushanda, uye kunotsiviwa mwedzi yega yega 3-6 pasi pemamiriro ekushanda akajairwa; huwandu hwemafuta anoshandiswa hunofanirwa kudzorwa pa 1/2-2/3 yehuwandu hwemabheyaringi kudzivirira kudonhedzwa kwekabhoni inodziya zvakanyanya kunokonzerwa nekupinza zvakanyanya kana kukweshana kwakaoma kwebheyaringi kunokonzerwa nekusapinza kwakakwana. Zvinorambidzwa kutsiva zvigadzirwa zvakakosha nemafuta akajairwa kudzivirira kukuvara kwemabheyaringi nekuda kwekutadza kwemafuta.

3.3 Kudzora Kurongeka Kwekuisa uye Kurongeka

 Panguva yekuisa, zvakakosha kuve nechokwadi chekuti kukanganisa kwekubatana pakati pe rotary union ne rotating shaft kuri ≤0.05mm, uye kumhanya kwekupedzisira kuri ≤0.03mm, kuitira kudzivirira simba rekutakura risina kuenzana uye kukurumidza kupera kwe sealing surface kunokonzerwa nekushanda kwe eccentric; mounting flange inofanira kunge yakati sandara, uye ma bolts e fastening anofanira kusimbiswa zvakaenzana kudzivirira deformation ye joints; usati washanda, zvakakosha kuita bvunzo yekumhanya isina mutoro, kutarisa kumhanya, kudedera uye kubuda kwemvura, uye kuiisa mu load operation chete mushure mekusimbisa kuti hapana chakaipa. Mushure mekudzima, zvinokurudzirwa kubvisa mvura mukati me medium, kunyanya medium inogadziriswa nyore nyore uye yakasimba (senge low-temperature cooling fluid), kudzivirira medium kuti isaome uye kukuvadza seals nema bearingers.

3.4 Kuongorora Nguva Dzose uye Kugadzirisa Matambudziko Ezvikanganiso

Gara uchitarisa maparamita ekushanda kwerotary union, kusanganisira kumhanya, tembiricha, vibration value uye leakage. Kana paine vibration isina kujairika (vibration value >2.5mm/s), seal leakage yakawandisa kana tembiricha yepamusoro yejoinhi (>80℃), zvinodikanwa kudzima kuti zviongororwe nenguva; gara uchitarisa kupera kwezvisimbiso. Kana zvikawanikwa zviine mavanga, kukuvara kana kukwegura pamusoro peseal, zvinodikanwa kutsiva seal assembly ye sealation imwechete uye zvinhu panguva kuti disawedzera kukanganisa.

4. Mhedziso

Sechinhu chakakosha pakunyatsojeka mumidziyo yepamusoro-soro, mashandiro emagetsi anotenderera anomhanya zvakanyanya anokanganisa zvakananga kugadzikana kwekushanda, kururama kwemuchina uye hupenyu hwebasa remuchina. Nekujekesa misimboti yayo mikuru yehunyanzvi, zvinodiwa zvehunyanzvi zvakagadziriswa kune minda yakasiyana, uye kunyatsotevedzera zvinodiwa zvekuchengetedza zvehutsanana, mafuta ekuzora uye kurongeka, hupenyu hwebasa rayo hunogona kuwedzerwa zvinobudirira uye mutengo wekushanda nekugadzirisa unogona kuderedzwa. Mukushandiswa kwakakodzera, zvakakosha kusarudza modhi yechigadzirwa chakakodzera zvichienderana nemamiriro chaiwo ekushanda (kumhanya, pakati nepakati, kumanikidzwa, tembiricha) kuti ive nechokwadi chekuti inoita basa rayo zvakanaka.
