Izigxivizo zemishini zamaphampu zingase zihlangabezane namaphutha athile kanye nezinkinga ngesikhathi sokusebenza, okungenzeka kubangelwe ukungabi khona kokusebenza okuvamile ngesikhathi sokufakwa.Ngakho-ke, ukuhlolwa okuhlukahlukene kufanele kwenziwe ngesikhathi sokufakwa, ikakhulukazi okubandakanya: izimpawu zemishini zamaphampu zingase zihlangabezane namaphutha kanye nezinkinga ngesikhathi sokusebenza.
1. Ububanzi bembobo nokujula komgodi wophawu lwepompo kufanele kuhambisane nobukhulu bomdwebo ohlanganisa uphawu, ngokuchezuka okuvamile okungu-± 0.13MM;Ukuchezuka kwe-Dimensional komkhono we-shaft noma we-shaft ngu-± 0.03mm noma ± 0.00mm-0.05.Hlola ukususwa kwe-axial ye-shaft, futhi ukufuduka okuphelele kwe-axial akufanele kudlule u-0.25mm;I-radial runout ye-shaft ngokuvamile ingaphansi kuka-0.05mm.Ukuphuma kwe-radial ngokweqile kungase kubangele: ukugqokwa kwemikhono ye-shaft noma shaft;Ukuvuza phakathi kwezindawo zokuvala kuyanda;Ukudlidliza kwemishini kuyaqina, ngaleyo ndlela kunciphisa impilo yesevisi yophawu.
2. Hlola ukugoba kwe-shaft.Ukugoba okuphezulu kwe-shaft kufanele kube ngaphansi kuka-0.07mm.Hlola ukuphuma kobuso bomgodi wokuvala.Ukuphuma kobuso bomgodi wokuvala akumele kudlule u-0.13MM.Uma ingaphezulu le-cavity yokuvala i-perpendicular ku-shaft, ingabangela uchungechunge lwamaphutha we-mechanical seal.Ngenxa yokuthi indlala yokuvala igxilile endlaleni evala uphawu ngamabholithi, ukuphuma ngokweqile kwembobo yokuvala kubangela ukuthambekela kokufakwa kwendlala, okubuye kubangele ukuthambekela kwendandatho emile evalayo, okuholela ekunyakazeni okungavamile kwalo lonke uphawu, okuyimbangela eyinhloko yokugqoka kwe-micro vibration.Ngaphezu kwalokho, ukuguga kophawu lwemishini kanye nophawu olusizayo lwe-shaft noma umkhono we-shaft nakho kuzoqina, Ngaphezu kwalokho, ukuzamazama okungavamile kophawu nakho kuzodala ukuguga nokukhathala kwensimbi noma iphinikhodi yokudlulisela, okuholela ngaphambi kwesikhathi. ukwehluleka kwesigxivizo.
3. Hlola ukuqondanisa phakathi kwembobo yembobo yesivalo sikamshini ukuze uthole iphampu kanye ne-shaft, futhi ukungaboni ngasolinye kuyoba ngaphansi kuka-0.13MM.Ukungaqondi kahle phakathi kwembobo yomgodi wokuvala kanye ne-shaft kuzothinta umthwalo oguquguqukayo phakathi kwezindawo zokuvala, ukuze kufinyezwe ukuphila kokusebenza kophawu.Ukuze ulungise ukuqondanisa, ukuqondanisa okungcono kungatholakala ngokulungisa i-gasket phakathi kwekhanda lepompo kanye nohlaka oluthwala noma ukucubungula indawo yokuxhumana.
Njengamanje, ngaphansi kwezidingo zokuphepha kokukhiqiza kanye nokuvikelwa kwemvelo, izimpawu zemishini ziye zasetshenziswa kabanzi.Izigxivizo zemishini zisetshenziswa kumishini yezimboni nezamabhizinisi ukuqinisekisa ukuthi akukho ukuvuza phakathi kwezindawo zokuvala eziguquguqukayo nezimile.Kunezinhlobo eziningi namamodeli wezimpawu zemishini zamaphampu ezimboni namaphampu amakhemikhali, kodwa ikakhulukazi kunamaphuzu okuvuza amahlanu:
① Ukuvalwa phakathi komkhono we-shaft kanye ne-shaft;
② Ukuvalwa phakathi kwendandatho ehambayo kanye nomkhono we-shaft;
③ Ukubekwa uphawu phakathi kwamasongo aguquguqukayo namile;
④ Ukuvalwa phakathi kwendandatho emile kanye nesihlalo esiyindandatho esinganyakazi;
⑤ Vala uphawu phakathi kwekhava yokugcina nomzimba wepompo.
