Iitywina zoomatshini zezinye zezona zinto zintsonkothileyo nezintsonkothileyo ezisisiseko zoomatshini, ezingawona malungu aphambili eentlobo ngeentlobo zempompo, iketile yokusabela, icompressor yeturbine, imoto entywilayo njalo njalo. Ukusebenza kwayo kokutywinwa kunye nobomi benkonzo kuxhomekeke kwizinto ezininzi, njengokukhethwa, ukuchaneka komatshini, ukufakela ngokuchanekileyo kunye nokusetyenziswa.
1. Indlela yokukhetha.
Ukutywinwa komatshini ngokweemeko zokusebenza kunye neepropathi eziphakathi, kukho ukumelana nobushushu obuphezulu, ukumelana nobushushu obuphantsi kwetywina lomatshini, itywina lomatshini, ukumelana noxinzelelo oluphezulu kunye nokumelana nokubola kwe-granules medium seal mechanical kunye nokuziqhelanisa nokufunxa itywina lomatshini lokukhanya kwe-hydrocarbon. medium, njalo njalo, kufuneka ngokuhambelana ukusetyenziswa ezahlukeneyo ukukhetha isakhiwo ezahlukeneyo kunye nezixhobo zokutywina oomatshini.
Ukukhethwa kweeparamitha eziphambili zezi: uxinzelelo lwe-seal cavity (MPa), ubushushu be-fluid (℃), isantya sokusebenza (m / s), iimpawu zolwelo kunye nokufakela indawo esebenzayo etywiniweyo, njl.
Imigaqo esisiseko yokukhetha yile:
1. Ngokutsho koxinzelelo lwegumbi lokutywina, isakhiwo sokutywinwa sizimisele ukwamkela uhlobo olulinganisiweyo okanye olungalinganiyo, ubuso obubodwa okanye ubuso obubini, njl.
2. Ngokutsho kwesantya sokusebenza, uhlobo olujikelezayo okanye olumileyo, uxinzelelo lwe-hydrodynamic okanye uhlobo olungenalo uqhagamshelwano lunqunywe.
3. Ngokweempawu zeqondo lokushisa kunye ne-fluid, misela izibini ze-friction kunye nezixhobo zokutywina ezincedisayo, kwaye ukhethe ngokuchanekileyo inkqubo yokukhusela i-mechanical circulation system efana ne-lubrication, ukuhlamba, ukugcinwa kobushushu kunye nokupholisa, njl.
4. Ngokwesithuba esisebenzayo sokutywinwa kofakelo, kuqinisekiswa ukuba i-multi-spring okanye i-spring single okanye i-wave wave iyamkelwa, kwaye ukulayishwa kwangaphakathi okanye kwangaphandle kwamkelwe.
