Izigxivizo zemishini ziyingxenye yezingxenye eziyisisekelo eziyinkimbinkimbi kakhulu neziyinkimbinkimbi, okuyizingxenye ezibalulekile zezinhlobo ezahlukene zephampu, igedlela le-reaction synthesis, i-turbine compressor, motor submersible nokunye. Ukusebenza kwawo kokubekwa uphawu nempilo yesevisi kuncike ezintweni eziningi, njengokukhethwa, ukunemba komshini, ukufakwa okulungile nokusetshenziswa.
1. Indlela yokukhetha.
Mechanical seal ngokwezimo zokusebenza kanye nezakhiwo ze-medium, kukhona ukumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi kwe-mechanical seal, uphawu lwemishini, ukumelana nokucindezela okukhulu kanye nokumelana nokugqwala kwama-granules medium mechanical seal futhi ivumelane nokushisa uphawu lomshini we-hydrocarbon ekhanyayo. medium, njll, kufanele kube ngokusho ukusetshenziswa ezahlukene ukukhetha isakhiwo ezahlukene kanye materials of uphawu mechanical.
Ukukhethwa kwamapharamitha ayinhloko yilawa: umfutho we-seal cavity (MPa), izinga lokushisa loketshezi (℃), isivinini sokusebenza (m/s), izici zoketshezi kanye nokufaka isikhala esisebenzayo esivaliwe, njll.
Imithetho eyisisekelo yokukhetha yilezi:
1. Ngokuhambisana nokucindezela kwegumbi lokubeka uphawu, isakhiwo sokubeka uphawu sinqunywa ukwamukela uhlobo olulinganiselayo noma olungalingani, ubuso obubodwa bokuphela noma ubuso obukabili, njll.
2. Ngokusho kwesivinini sokusebenza, uhlobo olujikelezayo noma olumile, ingcindezi ye-hydrodynamic noma uhlobo olungathintana naye lunqunywa.
3. Ngokusho kwezinga lokushisa kanye nezakhiwo eziwuketshezi, nquma amapheya okungqubuzana nezinto ezisizayo zokuvala, bese ukhetha ngendlela efanele isistimu yokuvikela ukujikeleza kophawu lomshini njengokugcoba, ukuwasha, ukugcinwa kokushisa nokupholisa, njll.
4. Ngokusho kwesikhala esisebenzayo sophawu lokufaka, kuqinisekiswa ukuthi i-multi-spring noma i-spring eyodwa noma i-wave spring yamukelwa, futhi ukulayishwa kwangaphakathi noma kwangaphandle kuyamukelwa.
