Ungakhetha njani i-twin screw extruder kwisicelo sakho sePVC
Isindululo sethu kukugcina zombini iijiyometri kuluhlu olufutshane xa kungekho nto ikhutshiweyo yinkqubo okanye ubungqina bomatshini. Emva koko susa ulungelelwaniso olungafanelekanga usebenzisa eyona nkqubo. "Umbhobho," "iprofayile" kunye "nebhodi" zichonga iintsapho zemveliso, hayi iinkcukacha ezipheleleyo ze-extrusion.
PVC umbhobho extrusion
Sipapasha zombini aPVC umbhobho conical screw umphandakunye aPVC umbhobho parallel screw umphanda. Eso sisizathu sokuthelekisa uqwalaselo, hayi isithembiso sokuba yonke isayizi ihambelana nombhobho ngamnye. Qala ngemilinganiselo yemveliso, ukuqulunqwa, umsebenzi woxinzelelo kunye neendawo ezifunekayo ezizinzileyo zemveliso.
Iphepha lombhobho we-conical libandakanya iibhendi zesicelo ze-16 ukuya kwi-63 mm, i-50 ukuya kwi-110 mm kunye ne-90 ukuya kwi-160 mm. Loo manani achaza izicelo zombhobho ezidwelisiweyo. Azikho iidayamitha ezijijekileyo kwaye azimiseli ubukhulu bobungakanani bombhobho wendalo yonke koomatshini beconical.
Iiprofayili kunye neebhodi
Kwiprofayili, bandakanya umzobo wecandelo, ubunzima ngemitha nganye, ulungelelwaniso lolungelelwaniso kunye neemfuno zokwamkelwa komgangatho. Kwibhodi, chonga ukuba iqinile okanye igwebugwebu kwaye uchaze ukutyeba okwamkelweyo, ukuxinana apho kufanelekileyo, iimfuno zomphezulu kunye ne-dimensional. Utshintsho kulwakhiwo lwemveliso lufanele ukuphononongwa ngokutsha kwenkqubo.
YethuPVC amagwebu-ibhodi isikhokelo Screw specicationigubungela ingcaciso emfutshane yokutshintsha ngakumbi. Siza kugcina uphononongo oluthile lwesicelo lwahlukileyo kuthelekiso lwejometri ngokubanzi. Imidibaniso yomthi esekwe kwiPVC nayo ifuna uphononongo lwazo lokuqulunqa; musa ukudlulisa isiphelo kwi-PE- okanye iPP-based composite kuba zombini iimveliso zibizwa ngokuba yiWPC.
Uluvula nini kwakhona ukhetho
Phinda ujonge inkcazo xa iresiphi, ifom yesondlo, umgangatho ojoliswe kuwo okanye ishedyuli yemveliso itshintsha. Kwinkqubo esele ingatshintshwanga, utshintshiselwano oluhambelana ngokuchanekileyo kufuneka luvavanywe phambi kokuba kucetywe ukuguqulwa komatshini. Ngomsebenzi owandisiweyo wemveliso, cela umthengisi womatshini ukuba ahlole umgca opheleleyo kunokuba athembise utshintsho ngejiyometri ejijwayo kuphela.
Ukuba umgca weconical okhoyo sele ugubungela umgangatho ofunekayo kunye noluhlu lwemveliso, siya kuqala sivavanye i-conical replacement ehambelanayo, singathengisi uguqulo olunxuseneyo njengophuculo oluzenzekelayo. Ingqiqo efanayo iyasebenza kumgca ohambelanayo owanelisayo. Ngomsebenzi omtsha wemveliso, khetha ulungelelwaniso olunesicelo esibonakalisiweyo esifanelekileyo; ixabiso eliphezulu lokuthenga okanye i-diameter enkulu ye-nominal ayikho loo mboniso.
Ngaba unokutshintsha okanye uguqule isikrufu esikhoyo kunye nomphanda?
I-conical twin screw barrel kunye ne-parallel twin screw barrel ayizondibano ezinokutshintsheka. Ngaphambi kokuxoxa ngokuguqulwa, fumana uphononongo olupheleleyo lomatshini. Ulungiselelo lokuphuma kwebhokisi yegiya, uqhagamshelo lweshaft, ukunyuswa komphanda kunye noyilo lweyunithi yokusetyenzwa kolu hlaziyo, kunye nokondla, ukukhupha umoya, ukufudumeza kunye nokupholisa ujongano.
Ngaphambi kokuba ndicebise ijiyometri yesijija eyahlukileyo
Xa ndiphonononga ingxaki ye-PVC extrusion, umbuzo wam wokuqala kukuba ngaba sibuyisela inkqubo yoqobo okanye sicela umatshini ukuba enze umsebenzi owahlukileyo. Ukutshintshwa kwezinto ezigugileyo kunye nokunyusa umthamo wemveliso kufuna ubungqina obahlukileyo. Andiyi kucebisa ukutshintsha phakathi kwe-conical kunye nezikrufu ezihambelanayo ngenxa yokuba umgca awuzinzanga.
Ukuba imveliso iyaguquguquka, ndiqala ngokucela ukuhlaziywa koqulunqo, iimeko zokutya, iirekhodi zokusebenza kunye neziphumo zokuhlolwa kwemveliso egqityiweyo. Ndifuna uxinzelelo, ubushushu, isantya se-screw kunye nesiphumo esamkelweyo esirekhodwe ngexesha elinye. Ukuthelekisa imveliso yayizolo kunye ne-avareji yanamhlanje indixelela kancinci ukuba izinto okanye imveliso itshintshile.
Emva koko, ndiphonononga ukucwangciswa koomatshini. Iphakheji yomzobo kufuneka ichonge indlela yokujikeleza, ijiyometri ejikijelwayo, umgama osembindini, uqhagamshelo lokuqhuba kunye nojongano lomgqomo. Kwindibano yokutshintshwa, ndikwafuna imilinganiselo ebotshelelwe kwizikhundla ezibiziweyo kuzo zombini izikrufu kunye nemibhobho yomibini. Inombolo yomzekelo sisiqalo, hayi imvume yokwenza.
Ndiye ndahlula izenzo ezinokwenzeka. Umba wesondlo ufuna uphando lokondla. Isinxibo esirhanelwayo sidinga ingxelo yokuhlola ehambelanayo. Uqulunqo olutshintshileyo lufuna ukuphononongwa kwenkqubo. Ukuba imveliso ekujoliswe kuyo iye yanda, izixhobo zokupholisa, ukutsalwa kunye nokusika kufuneka zingene kwingxoxo ngaphambi kokuba ndicebise iyunithi enkulu yokucubungula.
Ngaphambi kokuba umyalelo uqhubeke, ndingavuma ngezigaba ezibini zokwamkelwa: ukulungelelaniswa koomatshini kunye nokusebenza kwemveliso. Eyokuqala ijonga ukuba indibano ihambelana nomatshini; eyesibini ijonga ukuba into ekuvunyelwene ngayo ivelisa imveliso eyamkelekileyo phantsi kweemeko ezichaziweyo. Ukugcina ezo zigqibo zahlukene kunika umthengi indlela ecacileyo ukusuka kwingxaki yokuqala ukuya kwinkcazo yokubuyisela ekhuselekayo.

Ukuhlola kunye nokususa isikrufu, sebenzisa isityalo esivunyiweyo sokwahlula, ukupholisa kunye neenkqubo zokuphakamisa kunye nabasebenzi abaqeqeshiweyo. Yethui-parallel twin-screw clearance kunye nesikhokelo sokunxibaicacisa indlela yokucwangcisa irekhodi yomlinganiselo ohambelanayo.
Kufuneka uthumele ntoni kwi-RFQ kunye novavanyo lwemveliso?
Kutheni ndingavuma ukutshintshwa kwamanani ekhathalogu kuphela
Xa ndithelekisa iinketho zeNanhaiya ezipapashiweyo ze-conical kunye ne-parallel screw-barrel, ndiqala ukwahlula iifomathi zokucaciswa. Uluhlu lwe-conical lubandakanya izibini zedayamitha ezifana ne-Φ65/Φ132 kunye ne-Φ80/Φ156. La mangeniso ekhathalogu achonga ubume bomgqatswa; abaseka imveliso elinganayo okanye utshintshiselwano nenye indibano.Iimpawu zeNanhaiya conical
Umbhobho we-PVC we-parallel screw-barrel page upapasha uluhlu lwe-diameter ye-Φ45 ukuya ku-Φ150 mm kunye nomlinganiselo we-L / D we-32 ukuya kwi-38, kunye ne-customization ekhoyo. Loo manani achaza loo mveliso inikezelayo, ayizizo zonke i-trallel twin-screw extruder.Nanhaiya PVC umbhobho parallel iinkcukacha
Uqwalaselo olunxuseneyo oluyi-65 mm ngoko ke alunakuthathwa njengento yokutshintsha i-65/132 ye-conical assembly kuba zombini iinkcazo ziqulethe "65." Kwaye andizukutolika i-diameter ye-conical yesibini njengomlinganiselo we-L / D okanye i-diameter yombhobho ogqityiweyo.
Isiphetho sam kolu hlaziyo lwenkcazo kukuba ikhathalogu inokunceda iimveliso ezimfutshane, kodwa ayinakuvuma ukuguqulwa. Ngaphambi kokucebisa indibano, ndiza kufuna ukucwangciswa komatshini, imizobo yojongano, ukuqulunqwa kunye nethagethi yemveliso. Emva koko ndiza kwahlula ukuhambelana komgangatho ukusuka kwinkqubo yokusebenza esafuna ukuqinisekiswa.
Oko kunika umthengi umphumo wekhonkrithi ukusuka kuthelekiso: umzobo ochaziweyo-uphononongo kunye nobubanzi bovavanyo, kunesithembiso esingaxhaswanga sokuba ukutshintsha ijiyometri yesikrufu kuya kwandisa imveliso okanye ukunciphisa ukusetyenziswa kwamandla.

Imibuzo ebuzwa qho
Ngaba ii-parallel twin screw extruders zihlala zijikeleza?
No. Parallel ichaza screw-axis geometry, ngelixa co-rotation kunye counter-rotation ichaza intshukumo. Cacisa omabini amacandelo xa uthelekisa izixhobo. Kulo msebenzi wokukhetha i-PVC, uqwalaselo olufanelekileyo kunye nomsebenzi othe ngqo we-extrusion kufuneka usungulwe ngaphambi kokusebenzisa umthamo, ukuxuba okanye amabango amandla avela kwelinye uhlobo lomatshini we-twin-screw.
Ngaba i-conical twin screw extruder ihlala ingcono kwiPVC?
Hayi. Ukuqulunqwa kwePVC kunye nemfuno yemveliso ayikhethi ijometri ngokwayo. Thelekisa ulungelelwaniso olucetywayo lwe-conical nolungqameneyo phantsi kwesondlo esivunyelweneyo, umgangatho kunye neemeko zemveliso. Ukutshintshwa, umatshini ofakiweyo kunye nojongano oluvunyiweyo lunyanzelela ukhetho phambi kokuba uthelekiso lwenkqubo luvumele ulwakhiwo olwahlukileyo.
Loluphi uyilo olusebenzisa amandla amancinci ngekhilogram nganye?
Ileyibhile yejometri ayimiseli mpendulo. Ukulinganisa amandla kunye nobunzima bemveliso eyamkelekileyo ngexesha elinye, usebenzisa umda wesixhobo ochaziweyo. Thelekisa iindawo zokusebenza ezifunekayo kwishedyuli yemveliso. Umatshini unokuzisa ngaphezulu kwe-kg/h eyamkelekileyo ngelixa usebenzisa ngaphezulu kwe-kWh ngekhilogram eyamkelekileyo ngelo xesha.
Ngaba isikrufu seconical kunye nebhareli singabuyisela isethi enxuseneyo?
Ayizizo iindibano ezinokutshintshelana. Ukuguqulwa kufuna uphononongo loyilo lomatshini, iziphumo zebhokisi yegiya, uqhagamshelo lweshaft, ukunyuswa kunye nojongano lwenkqubo. Ngomyalelo oqhelekileyo wokutshintsha, khankanya indibano ehambelanayo yomatshini ofakelweyo. Musa ukuvuma uguqulo olusuka kwimodeli yenombolo yekhathalogu okanye ixabiso ledayamitha ekwabelwana ngayo.
Inombolo yomzekelo efana no-65/132 ikuxelela ntoni?
UNanhaiya udwelisa i-Φ65/Φ132 njengesikruru sombhobho edityanisiweyo. Qinisekisa iindawo zedimension kunye nejometri epheleleyo kumzobo.
