Njengengxenye ewumgogodla yezinhlelo zokulawula uketshezi, ukusebenza kwamavalvu e-hydraulic solenoid kuthinta ngqo ukuthembeka nokusebenza kahle kwemishini. Inqubo yokubumba iyisici esibalulekile ekunqumeni ikhwalithi yevalvu ye-solenoid, ebandakanya ukusetshenziswa okuphelele kokukhethwa kwezinto ezibonakalayo, ukwakheka kwesakhiwo, kanye nobuchwepheshe bokukhiqiza. Lesi sihloko sizochaza ngokuhlelekile amaphuzu abalulekile wenqubo yokubumba i-hydraulic solenoid valve ngokombono wedizayini yokubunjwa, ukubumba okubalulekile, kanye{2}}nokucubungula kokuthunyelwe.
I. Ukwakhiwa Kwesikhunta Nokukhiqiza
Amavalvu e-hydraulic solenoid ngokuvamile abunjwa kusetshenziswa ukubumba komjovo onembayo noma{0}}ukusakaza. Ukunemba kwesikhunta kuthinta ngokuqondile ukuzinza kwe-dimensional yomzimba we-valve. Idizayini yesikhunta igxile ebhalansini yesiteshi sokugeleza kanye nesakhiwo sesistimu yokupholisa: ububanzi beshaneli eyinhloko kufanele bufane nokugeleza kwepulasitiki encibilikayo, futhi iziteshi zamagatsha kufanele zibe nesigaba esiyisiyingi{3}}sokunciphisa ukulahleka kwengcindezi. Iziteshi zamanzi okupholisa kufanele zisakazwe ngokulinganayo endaweni yesikhunta, kuqinisekiswe ukuhluka kwezinga lokushisa ngaphakathi kwe-±2℃ukuze kuvinjelwe ukunamathela komgogodla wevalvu ngenxa yokushwabana okungalingani. Emizimbeni yamavalvu ensimbi esebenza ngaphansi-izimo zokucindezela okuphezulu, isikhunta sokufa{8}}sokusakaza kufanele senziwe ngensimbi eshisayo engu-H13{10}}esebenzayo futhi ene-nitrided ukuze kwandiswe ubulukhuni bobuso (Obukhulu noma obulingana ne-HV900) ukuze bumelane nemithwalo ephindaphindayo.
II. Inqubo Yokubumba Okubalulekile
1. I-Plastic Valve Body Molding
Amapulasitiki obunjiniyela afana ne-PA66+GF30 (equkethe u-30% we-glass fiber) ngokuvamile akhethwa ngenxa yokungazweli nokuqina kwawo. Imingcele yokubunjwa komjovo idinga ukulawula okuqinile: izinga lokushisa lomgqomo libekwe ku-260-280 degree, ingcindezi yomjovo 80-120 MPa, kanye nesikhathi sokubamba esilungisiwe ngokuvumelana nobukhulu bodonga (imvamisa imizuzwana engu-1-3/mm). Ukuze kuqedwe ukucindezeleka kwangaphakathi, i-annealing ku-80℃iyadingeka ngemva kokudilizwa, okulandelwa ukubanjwa kwamahora angu-2 ukuze kuqiniswe izilinganiso.
2. I-Metal Valve Ukubumba Umzimba
Ngezinhlelo zokusebenza zokucindezela okuphezulu{{0}okuphezulu, i-aluminium alloy (efana ne-ADC12) noma i-brass die-isetshenziswa ukusakaza. Amapharamitha enqubo yokusakaza ye-Die{4}ilawa: izinga lokushisa lengxubevange engu-650-700℃, izinga lokushisa lesikhunta 180-220℃, kanye ne-boost pressure 50-80 MPa. Izindawo zokuvala ezibucayi zithola ukuqedwa kwe-CNC okulandelayo ukuze kuqinisekiswe ukucaba Okungaphansi noma okulingana no-0.01 mm. I-vacuum impregnation isetshenziselwa ukugcwalisa ukukhubazeka kwe-microporous, okwandisa isilinganiso sokucindezela sibe ngaphezu kuka-35 MPa.
III. Electromagnetic Assembly Integration Process
Ikhoyili ye-electromagnetic ilinyazwa kusetshenziswa umshini wokujika ozenzakalelayo. Intambo ene-enameled enobubanzi obungu-0.3-0.5mm ilimele ngokuminyene izendlalelo eziningi, ifakwe ifilimu ye-polyimide phakathi kwezingqimba. Izinto eziwumgogodla yi-DT4 kagesi ehlanzekile yensimbi, edonswa ukuze kuncishiswe ukuphoqelelwa (Ngaphansi noma okulingana no-80A/m), futhi ixhunywe kusiqu se-valve nge-brazing esekelwe esiliva ukuze kuqinisekiswe isikhathi sokuphendula esingaphansi kuka-10ms. Ikhoyili kanye nomzimba we-valve zimbozwe nge-epoxy resin, ngokumelana nokufakwa kwe-Insulation Okukhulu noma okulingana no-100MΩ ngemva kokwelashwa.
IV. Okuthunyelwe-Ukucutshungulwa kanye Nokulawulwa Kwekhwalithi
Ivalvu ye-solenoid ebunjiwe idlula-emshinini wokulinganisa wokuhlanganisa izingxenye ezintathu ukuze ihlole ubukhulu bokhiye (okufana nokubekezelela indawo yesihlalo sevalvu engu-±0.005mm) futhi iphumelele ukuhlolwa kokungangeni komoya (ukunemba kokuhlolwa kokuvuza kwe-helium okungu-1×10⁻⁹ Pa·m³/s). Emizimbeni yamavalvu epulasitiki, -ukuhlolwa komjikelezo wezinga lokushisa eliphezulu ukusuka ku--40℃kuya ku-120℃nakho kwenziwa ukuze kuqinisekiswe ukumelana nokuchwensa kwento.
Isiphetho
Inqubo yokubumba yama-hydraulic solenoid valves imele ukuphambana kwesayensi yezinto, ukukhiqizwa okunembayo, kanye nokuguquguquka koketshezi. Ngokuthuthukisa idizayini yokubumba, ukulawula ngokunembile imingcele yokubumba, kanye nokuthuthukisa{1}}izinqubo zokucubungula okuthunyelwe, ukuvumelana komkhiqizo nokuqina kungathuthukiswa kakhulu. Ngokuzayo, ngokuthuthuka kokukhiqiza okungeziwe kanye nobuchwepheshe bezinto eziyinhlanganisela, ukubumba kwe-solenoid valve kuzothuthukela ekukhiqizeni okungasindi kanye nobuhlakani.
