Imowudi yokudluliselwa kwetorque phakathi kwesikrufu kunye ne-mandrel sisitshixo sokuqonda i-groove ye-screw enzulu.Ukuhanjiswa kwetorque phakathi kwesixhobo sokujiya kunye ne-mandrel ekuqaleni kwaqhagamshelwa ngezitshixo ezisicaba, nto leyo engapheleli nje ekunciphiseni ukujula kwesikrufu se-screw kunye nokwandisa umthamo wasimahla wesikrufu, kodwa namandla amaqhosha acaba akakwazanga ukuhlangabezana neemfuno ze-screw. imisebenzi ethile yemveliso.
- 1.Spiral groove ubunzulu
Ubunzulu be-screw groove yiparameter ebalulekileyo yeiwele – screw extruder.Ngokuqhelekileyo ibonakaliswa ngokungathanga ngqo ngomlinganiselo we-screw diameter kunye ne-screw root diameter.Ixabiso liyiparameter ebalulekileyo ukubonisa umgangatho wobugcisa we-twin screw extruder.Okwangoku, umlinganiselo wedayamitha yangaphandle yesikrufu ukuya kwidayamitha yengcambu yesikrufu kwisizukulwana samva nje (isizukulwana sesithandathu) i-coaxial twin-screw extruder emelwe yiWP yaseJamani nguD/Di = 1.55.Kukho izinto ezininzi ezithintela uD / Di, ukongeza kumgama osembindini weshafu yokuphuma kwebhokisi yegiya yesikrufu sokuqhuba, isikrufu ngokwaso sinempembelelo enkulu kwi-D/Di: njengokumelana nokucheba kwe-screw mandle-shaft, imowudi yokudlulisa itorque phakathi i-screw element kunye ne-mandle-shaft, isakhiwo se-screw element ngokwayo, njl.
- (1) Ukuphumelela ekukhetheni izinto eziphathekayo, iteknoloji yokucubungula kunye nokusebenza kobushushu bokusebenza kwe-mandrel kwenza ukuba umthamo we-torque ye-mandrel uphuculwe kakhulu, kunye nomlinganiselo wobude bobubanzi be-screw ukunyuka ukusuka kwi-36 yokuqala ukuya kuma-50, okanye ngaphezulu.
- (2) Ukuphumelela kwetekhnoloji yenkqubo ekhethekileyo yokuqhubela igiya ye-co-directional twin-screw extruder ibonelela ngesiqinisekiso sothumelo lwamandla kwigalelo letorque efunwa sisikrufu esinzulu segroove phantsi kwemeko yomgama osembindini ongaguqukiyo, okwenza isikrufu sibe nguD/ Di uya 1.55.
- (3) Imowudi yokudluliselwa kwetorque phakathi kwesikrufu kunye ne-mandrel sisitshixo sokuqaphela i-groove enzulu ye-screw.Ukuhanjiswa kwetorque phakathi kwesixhobo sokujiya kunye ne-mandrel ekuqaleni kwaqhagamshelwa ngezitshixo ezisicaba, nto leyo engapheleli nje ekunciphiseni ukujula kwesikrufu se-screw kunye nokwandisa umthamo wasimahla wesikrufu, kodwa namandla amaqhosha acaba akakwazanga ukuhlangabezana neemfuno ze-screw. imisebenzi ethile yemveliso.Ukusebenzisa i-multi-key torque transmission ngendlela ye-involute inokuphucula kakhulu ubunzulu be-screw groove phantsi kobubanzi obufanayo bangaphandle be-screw.Kwiminyaka yakutshanje, ngelixa ifunda kubuchwephesha obuphambili bangaphandle, iTshayina yenze impumelelo enkulu ekuqhubeni nasekuveliseni.Okwangoku, ikwazile ukwenza ulwakhiwo lwe-involute spline kunye nefom yoqhagamshelo efanayo ne-screw yangaphandle, ngaloo ndlela yenza impumelelo enkulu kubunzulu be-screw groove.
- (4) Ukuphumelela kwesakhiwo sesiqalelo.Ubume bebhloko yokuxova busombulula itekhnoloji ephambili yokuvelisa, ulwakhiwo lwayo lutshintsha ukusuka kuhlobo lweqhekeza elinye, uhlobo lokudibanisa ukuya kuhlobo olukhoyo oludibeneyo, ngaloo ndlela iqinisekisa ubunzulu be-screw groove ukusuka kumandla wento, nayo yenza ukulungelelaniswa kokudibanisa isikrufu kunye nendibano ye-screw ethembekileyo ngakumbi kwaye ilungele.
Ukushwankathela, impumelelo kwimiba yenkqubo yothumelo lwegiya, amandla e-shear e-mandrel, i-torque yokuhambisa i-screw element kunye ne-mandrel, kunye noyilo kunye nokuveliswa kwezinto ezisijiva kuqinisekisa uphuhliso oluyimpumelelo lwesizukulwana esitsha sesantya esiphezulu kunye nesijiva esinzulu. i-extruder.
- 2.Into entsha yesikrufu
I-Synthetic twin screw extruder yinxalenye engundoqo yesikrufu, emva kokufika kwe-synthetic double screw extruder, kwaye uphuhliso lwescrew kunye nescrew element ibisoloko iluphando lomphuhlisi kunye necala eliphambili, ulwakhiwo lwesijiva ukusuka kuphuhliso oludityanisiweyo kwangoko ukuya “kwibhloko yesakhiwo. ”, imisonto emithathu ukusuka entloko ukuya entloko, kamva xa ulwakhiwo oluphindwe kabini, uhlobo lwezinto ezijijwayo, ulwakhiwo kunye nokwahlukana komsebenzi.Phuhlisa uhlobo lomxube wokuzicoca wohlobo lwesikrufu, uhlobo lomphetho wesixhobo somxube wohlobo lwesikrufu, isikrufu esinamazinyo, isikrufu sokulawula isikrufu, njl.njl., i-twin screw extruder screw element eyenziwe ngokutsha, ukongeza kunye nokugqibelela, ukomeleza kunye nokuphucula indlela i-twin screw extruder yokuxuba kunye nefuthe leplastiki, ukusasazwa, ukucheba, uxinzelelo, kunye nokulungelelaniswa.
- 3.Iiparamitha zokukala itorque yebhokisi yeGear
Ipharamitha yebakala le-torque i-M / A3 yebhokisi yebhokisi yinto ebalulekileyo yesalathisi somsebenzi we-coaxial twin-screw extruder.Ixabiso layo limele inqanaba lobugcisa be-coaxial twin-screw extruder kwaye limele umthamo we-torque yebhokisi yebhokisi phantsi komgama othile weziko lokujikijela.Ngenxa yobungcali befom yokuhanjiswa kwe-coaxial twin-screw extruder, i-torque yegiya ifakwe kwibhokisi yegiya nge-shaft-speed shaft.Ngokunciphisa kunye nokusabalalisa i-torque, i-torque idluliselwa kwi-twin-screw ngama-shafts amabini aphumayo kunye nomgama olinganiselwe ophakathi phantsi kwemeko ye-axial force enkulu.Ngoko ke, ipharamitha yomlinganiselo we-M / A3 phakathi komgama ophakathi kwe-shaft yokuphuma kunye ne-torque yokuphuma ibe ngumqondiso obalulekileyo wokulinganisa inqanaba lobugcisa.Ke uyilo lwebhokisi yegiya ye-twin screw extruder inzima kakhulu xa kuthelekiswa noyilo kunye nophuhliso lwenkqubo yokuhanjiswa kwegiya ngokubanzi.Okwangoku, iChina yenze impumelelo enkulu kwimowudi yokuhanjiswa kwegiya, ukuhanjiswa kwetorque efanayo kunye nesisombululo samandla e-axial.Iiparameters zebakala le-torque ye-extruder yokulinga zitshintshiwe ukusuka kwi-4.Isixhenxe siya phezulu ukuya kwisibhozo.Ibeka isiseko esihle sophuhliso lwesantya esiphezulu kunye nebhokisi yegiya ephezulu ye-torque yemveliso ye-extruder.
Ngokubhekiselele kubomi benkonzo yebhokisi yegiya, ngokuphucula kunye nokuqhutywa luhlobo olutsha lwendlela yamatshaneli amaninzi, kungekuphela nje ukuphucula kakhulu umthamo wokuhambisa, kwaye ngolungiselelo olufanelekileyo lwe-axis, isombulule igiya kunye nokuhanjiswa komthwalo, Yanciphisa kakhulu idrive yegiya kunye nenkqubo yokusebenza kwamandla ongezelelweyo, okwenza ixesha elide lithintele ubomi benkonzo yebhokisi yegiya yokusebenza okuchasene nokudinwa kwegiya, ukusebenza kwenkqubo yokuthwala iphuculwe kakhulu, emva kokwamkela i-multiplex drive, imveliso Uxinzelelo lwe-diameter ye-axle ye-axle direction yehla kakhulu, ngoko ke, ngeendlela ezininzi zokuphucula i-gear, i-thrust bearing system, inxalenye yokusabalalisa i-torque yobomi benkonzo yokuthwala, ubomi obuyilwe ukuya kuthi ga kwi-10 a.
- 4.Isantya seScrew
Isantya se-Screw yenye iparameter ebalulekileyo yokulinganisa ibakala lokusebenza kwe-extruder kunye nolwalathiso olufanayo kwaye yindlela ebalulekileyo yokuphucula isalathisi sokusebenza kwe-extruder.Ichaphazela ngokuthe ngqo iiparamitha zebakala le-torque kunye nomthamo wokuvelisa wezixhobo.Ukonyuka kwesantya sokujikeleza isikhonkwane ikakhulu kuxhomekeke kubuchule obutsha kunye nophuhliso lwenkqubo yokuhambisa igiya, ukukwazi kwetorque ekrwada ngaphantsi kunye nokusebenza okuchasene nokudinwa, ngokuphuhlisa uhlobo olutsha lothumelo lwendlela kunye nokwandisa uyilo lokuyila, ukhetho lwamacandelo aphambili angeniswe ngaphandle. , kuthetha, ukujongwa ngokungqongqo kwezixhobo zokuphotha ezijijwayo kunye nophuculo lwenkqubo yonyango lobushushu, kunye nesixhobo sokuphotha kunye nesixhobo sokusonta, ukugqabhuka kwe-spline okubandakanya ukwenziwa ngendlela yosasazo olufanayo loxinzelelo, okwenza kube lula ukonyuka kwesantya sokujikeleza, bekukwi umatshini omncinci we-speed high-speed synthetic synthetic-screw extruder ngokusebenzisa uvavanyo lwamashishini.
- 5.Umthamo wemveliso
Inqanaba lobugcisa kunye nokusebenza kwezixhobo zijolise ekuphuculeni amandla okuvelisa, ukunciphisa ukusetyenziswa kwamandla kunye nokuphucula ukuthembeka.Umthamo wemveliso yeyona nto iphambili yokuvavanya ukusebenza kweyunithi: (1) phucula isantya se-screw, uhlobo olufanayo lwemveliso lunokuphinda-phindwe kabini; (2) ukusetyenziswa kwesikrufu esinzulu se-screw groove, ukwandisa umthamo okhululekileyo, uphucule isantya seyunithi kunye nomthamo wexesha leyunithi yothutho; (3) ukusetyenziswa kwesikrufu samawele kunye nempompo yegiya kudityaniswe nendlela yobugcisa, ukuphucula ukuthembeka kwebhokisi yothumelo, ukunciphisa amandla e-axial athwalwa yigiya, kuphelisa umda we-axial force ukunciphisa i imveliso yento, phucula imveliso ye-extruder.
