Njengenxalenye ephambili yeenkqubo zokulawula ulwelo, ukusebenza kweevalvu ze-hydraulic solenoid zichaphazela ngokuthe ngqo ukuthembeka kunye nokusebenza kakuhle kwesixhobo. Inkqubo yokubumba yeyona nto iphambili ekumiseleni umgangatho wevalve ye-solenoid, ebandakanya ukusetyenziswa okubanzi kokukhethwa kwezinto, uyilo lolwakhiwo, kunye nobugcisa bokuvelisa. Eli nqaku liza kuchaza ngokucwangcisiweyo amanqaku aphambili enkqubo yokubumba ivalve ye-hydraulic solenoid ngokwembono yoyilo lokungunda, ukubumba izinto, kunye -nokulungiswa kweposi.
I. Uyilo lokungunda kunye nokuVeliswa
Iivalvu ze-hydraulic solenoid ziqhele ukubunjwa kusetyenziswa isitofu esichanekileyo sokubumba okanye{0}}ukuphosa. Ukuchaneka komngundo kuchaphazela ngokuthe ngqo uzinzo lwe-dimensional yomzimba wevalvu. Uyilo lokungunda lugxile kwibhalansi yomjelo wokuqukuqela kunye noyilo lwenkqubo yokupholisa: ubukhulu bejelo elingundoqo kufuneka lihambelane nokuhamba kweplastiki yokunyibilika, kwaye imisele yesebe kufuneka ibe nesetyhula{3}}icandelo lokunciphisa ilahleko yoxinzelelo. Imijelo yamanzi okupholisa kufuneka isasazwe ngokulinganayo kumngxuma wokungunda, kuqinisekiswe umahluko wobushushu phakathi kwe-±2 idigri ukuthintela ukuncamathela kondoqo wevalvu ngenxa yokushwabana okungalinganiyo. Kwimizimba yevalvu yentsimbi esebenza phantsi{7}}kweemeko zoxinzelelo oluphezulu, fa{8}}imolds yokuphosa kufuneka yenziwe nge-H13 eshushu{10}}yentsimbi esebenzayo yentsimbi kunye ne-nitrided ukunyusa ubulukhuni bomphezulu (Mkhulu okanye bulingana ne-HV900) ukumelana nomthwalo ophindaphindiweyo.
II. Inkqubo yokubumba izinto eziphathekayo
1. IValve yePlastiki yokuBumba uMzimba
Iiplastiki zobunjineli ezifana ne-PA{0}}GF30 (equlathe i-30% yefiber yeglasi) zihlala zikhethwa ngenxa yokunganyangeki kunye nokomelela kwazo. Iiparamitha zokubumba i-injection zifuna ulawulo olungqongqo: iqondo lokushisa lomgqomo libekwe kwi-260-280 degree, uxinzelelo lwe-injection 80-120 MPa, kunye nexesha lokubamba lihlengahlengiswe ngokobunzima bodonga (ngokuqhelekileyo i-1-3 imizuzwana / mm). Ukuphelisa uxinzelelo lwangaphakathi, i-annealing kwi-80℃iyadingeka emva kokudiliza, ilandelwa yi-2 yeyure ukubamba ukuzinzisa imilinganiselo.
2. Metal Valve Ukubumba uMzimba
Kusetyenziso oluphezulu{{0}loxinzelelo oluphezulu, ialluminiyam ialloy (efana ne-ADC12) okanye ibrass die{2}}isetyenziswa rhoqo. Die -iparamitha zenkqubo yokuphosa zezi: ubushushu be-alloy 650-700 degree, iqondo lobushushu lokungunda 180-220 degree, kunye noxinzelelo lokunyusa 50-80 MPa. Imiphezulu yokutywina ebaluleke kakhulu idlula emva kokugqitywa kwe-CNC ukuze kuqinisekiswe ukuba flatness Ngaphantsi okanye ilingana no-0.01 mm. I-vacuum impregnation isetyenziselwa ukuzalisa iziphene ze-microporous, ukwandisa umlinganiselo woxinzelelo ukuya phezulu kwe-35 MPa.
III. Inkqubo yoManyano lweNdibano yoMbane
Ikhoyili ye-electromagnetic inxeba usebenzisa umatshini wokujija ozenzekelayo. Ucingo olune-enameled olunobubanzi obuyi-0.3-0.5mm lunenxeba elixineneyo kwiileya ezininzi, kunye nokugqunywa kwefilimu ye-polyimide phakathi kweeleya. Izinto ezingundoqo yi-DT4 yombane yentsimbi ecocekileyo, i-annealed ukunciphisa ukunyanzeliswa (Ngaphantsi okanye ilingana ne-80A / m), kwaye idibene ne-valve stem nge-brazing-based brazing ukuqinisekisa ixesha lokuphendula elingaphantsi kwe-10ms. Ikhoyili kunye nomzimba wevalvu zigqunywe nge-epoxy resin, kunye ne-insulation resistance ye-Greater than or equal to 100MΩ emva kokunyanga.
IV. IPost-Ukusetyenzwa kunye noLawulo loMgangatho
Ivalve ebunjiweyo ye-solenoid ingena kumatshini wokulinganisa wolungelelwaniso oluthathu ukuze ihlole imilinganiselo engundoqo (efana nokunyamezela isihlalo sevalvu yokuvula indawo eyi-±0.005mm) kwaye iphumelele uvavanyo lokungangeni moya (i-helium yokuvuza ukuchaneka kwe-1×10⁻⁹ Pa·m³/s). Kwimizimba yevalvu yeplastiki, uvavanyo lomjikelo wobushushu obuphezulu-ukusuka kwi -40℃ukuya kwi 120℃nalo lwenziwa ukuqinisekisa ukuxhathisa kwemathiriyeli.
Ukuqukumbela
Inkqubo yokubumba i-hydraulic solenoid valves imele ukuhlangana kwesayensi yezinto, ukuveliswa okuchanekileyo, kunye ne-fluid dynamics. Ngokulungisa uyilo lokungunda, ukulawula ngokuchanekileyo iparameters zokubumba, kunye nokuphucula isithuba{1}}iinkqubo zokucutshungulwa, ukungaguquguquki kwemveliso kunye nokuqina kunokuphuculwa kakhulu. Kwixesha elizayo, ngenkqubela phambili yokwenziwa kwezixhobo ezongezelelweyo kunye nethekhnoloji yemathiriyeli ehlanganisiweyo, ukubumba ivalvu ye-solenoid kuya kuphuhla ngakumbi ukuya kubunzima bokukhanya kunye nokwenziwa ngobukrelekrele.
