Ubudlelwane boQhagamshelwano
Ibhalansi yobushushu yeisitofu sokungundailawula ukuqhuba kobushushu bomatshini wokubumba inaliti kunye nokungunda ngundoqo ekuveliseni iindawo ezibunjiweyo zenaliti.Ngaphakathi kwesikhunta, ubushushu obuziswe yiplastiki (njenge-thermoplastic) idluliselwe kwizinto eziphathekayo kunye nentsimbi ye-mold ngokusebenzisa i-radiation ye-thermal, kwaye idluliselwe kumanzi okudlulisa ubushushu ngokusebenzisa i-convection.Ukongeza, ubushushu budluliselwa kwi-atmosfera kunye nesiseko sokungunda ngemitha ye-thermal.Ubushushu obufunxwa lulwelo lokudlulisa ubushushu buthathwa ngumatshini wobushushu bokungunda.Ibhalansi ye-thermal yokubumba ingachazwa njenge: P = Pm-Ps.Apho i-P bubushushu obuthathwe ngumatshini wobushushu bokungunda;I-Pm bubushushu obuveliswa yiplastiki;I-Ps bubushushu obukhutshwa ngumngundo emoyeni.
Iimeko zangaphambili zolawulo olusebenzayo lweqondo lokushisa lokungunda Inkqubo yokulawula ubushushu iqulethwe ngamacandelo amathathu: isikhunta, isilawuli sobushushu sokungunda, kunye nolwelo lokuhambisa ubushushu.Ukuqinisekisa ukuba ubushushu bunokongezwa okanye bususwe kubumba, inxalenye nganye yenkqubo kufuneka ihlangabezane nale miqathango ilandelayo: Okokuqala, ngaphakathi kwesikhunta, indawo yomphezulu wejelo lokupholisa kufuneka ibe nkulu ngokwaneleyo, kunye nobubanzi. wembaleki kufuneka ahambelane nomthamo wempompo (uxinzelelo lwempompo).Ukuhanjiswa kweqondo lokushisa kwi-cavity kunempembelelo enkulu kwi-deformation inxalenye kunye noxinzelelo lwangaphakathi.Ukusetwa okufanelekileyo kweetshaneli zokupholisa kunokunciphisa uxinzelelo lwangaphakathi, ngaloo ndlela kuphuculwe umgangatho weendawo ezibunjiweyo zesitofu.Iyakwazi nokunciphisa ixesha lomjikelo kunye nokunciphisa iindleko zemveliso.Okwesibini, umatshini wokushisa wokubumba kufuneka ukwazi ukugcina ubushushu bobushushu bokuhambisa ubushushu buhlala buhlala ngaphakathi kwinqanaba le-1 ° C ukuya kwi-3 ° C, kuxhomekeke kwiimfuno zomgangatho weendawo ezibunjiweyo zenaliti.Okwesithathu kukuba i-fluid yokudlulisa ubushushu kufuneka ibe ne-conductivity enhle ye-thermal, kwaye okona kubaluleke kakhulu, kufuneka ikwazi ukungenisa okanye ukuthumela ngaphandle isixa esikhulu sobushushu ngexesha elifutshane.Ukusuka kwimbono ye-thermodynamic, amanzi angcono ngokucacileyo kuneoli.
Umgaqo osebenzayo Umatshini weqondo lokushisa lokubumba uqulunqwe itanki yamanzi, inkqubo yokufudumeza kunye nokupholisa, inkqubo yokuhambisa amandla, inkqubo yokulawula inqanaba lolwelo, inzwa yobushushu, i-injection port kunye namanye amacandelo.Ngokuqhelekileyo, impompo kwinkqubo yokuhanjiswa kwamandla yenza ukuba umbane oshushu ufikelele kwi-mold ukusuka kwitanki yamanzi exhotywe nge-heater eyakhelwe-ngaphakathi kunye ne-cooler, kwaye emva koko ukusuka kwi-mold ukuya kwi-tank yamanzi;inzwa yobushushu ilinganisa ubushushu bolwelo olushushu kwaye idlulisela idatha kwindawo yolawulo yoMlawuli.
Umlawuli ulungelelanisa ubushushu bombane oshushu, ngaloo ndlela ulungelelanisa ngokungathanga ngqo ubushushu besikhunta.Ukuba umatshini wokushisa wokungunda ukwimveliso, iqondo lokushisa lokungunda lidlula ixabiso elimiselweyo lomlawuli, umlawuli uya kuvula i-valve ye-solenoid ukudibanisa umbhobho wokungena kwamanzi kude kube yiqondo lokushisa lobushushu obushushu, oko kukuthi, iqondo lokushisa. ukungunda kubuyela kwixabiso elimiselweyo.Ukuba iqondo lokushisa lokubumba lingaphantsi kwexabiso elimiselweyo, umlawuli uya kuvula i-heater.
