Izitywina zoomatshini zezinye zezona zinto zintsonkothileyo nezintsonkothileyo ezisisiseko zoomatshini, ezingawona macandelo aphambili eentlobo ngeentlobo zempompo, iketile yokusabela, i-compressor ye-iturbine, i-motor submersible njalo njalo.Ukusebenza kwayo kokutywinwa kunye nobomi benkonzo kuxhomekeke kwizinto ezininzi, ezifana nokukhethwa, ukuchaneka komatshini, ukufakela ngokuchanekileyo kunye nokusetyenziswa.
1. Indlela yokukhetha.
Itywina lomatshini 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 nokulungelelanisa ukufunxa itywina lomatshini lokukhanya kwe-hydrocarbon. eliphakathi, njl., kufuneka libe ngokuhambelana nokusetyenziswa okuhlukeneyo ukukhetha isakhiwo esahlukileyo kunye nezixhobo zokutywinwa koomatshini.
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 njl.
2. Ngokutsho kwesantya sokusebenza, uhlobo olujikelezayo okanye olusisigxina, uxinzelelo lwe-hydrodynamic okanye uhlobo olungenalo uqhagamshelwano lunqunywe.
3. Ngokutsho kweqondo lokushisa kunye neempawu ze-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 kokufakela, kuqinisekiswa ukuba i-spring-spring okanye enye intwasahlobo okanye i-wave wave yamkelwa, kwaye ukulayishwa kwangaphakathi okanye kwangaphandle kwamkelwe.
