Intermeshing Conical Twin Screw

I-Nanhaiya screw ngumvelisi wokuqala waseTshayina osebenza ngokukhethekileyo kwimveliso ye-intermeshing conical twin screw. Ngaphezulu kweminyaka elishumi yamava koomatshini beplastiki, sisebenzisa iinkqubo zokuvelisa ezikumgangatho ophezulu kunye nezixhobo ukuyila nokwenza uluhlu olubanzi lwezikrufu. Iimveliso zethu zibonelela ngamaxabiso akhuphisanayo kwaye zigubungela uluhlu olubanzi lweemarike zaseYurophu nezaseMelika. Sijonge phambili ekubeni liqabane lakho lexesha elide eTshayina.

Intshayelelo yeMveliso

Esi sikruru sewele esidibanisayo senziwe ngentsimbi eyi-38CrMoAla. Imathiriyeli ekrwada ibalulekile ekujikeni ukusebenza, kwaye sikhetha amandla aphezulu kunye nentsimbi engagugiyo kubavelisi bentsimbi abaziwayo baseTshayina abahlangabezana nemigangatho yesizwe (GB/T 3077).

Sisebenzisa inkqubo yokuqengqeleka komsonto. Le nkqubo idala iprofayili yentambo egcweleyo, eyomeleleyo, inqanda ukuqhekeka. Ikwalawula impazamo yokuphosa intambo ukuya ku-≤0.1mm, iqinisekisa ukubandakanyeka okufanayo kunye nokunciphisa ukukhulula.

I-Nanhaiya's intermeshing conical twin screw barrels ziye zadlula kwi-R&D ezininzi kunye nophuculo kwaye ngoku zidityaniswe kwimigca yemveliso eyahlukeneyo yabavelisi, ukuphumeza ukusebenza komgangatho. Sinikezela ngewaranti yeminyaka eyi-1-2, kuxhomekeke kumlinganiselo othile wokongezwa kwezinto. Imigqomo ye-Nanhaiya ingena kwinkqubo ye-nitriding, kunye ne-2mm engqindilili ye-nickel-tungsten alloy alloy spray-welded kwiindawo ezithandwa kakhulu. Oku kwandisa ukuqina komphezulu we-barrel ukusuka kwi-HRC55-60 ukuya ngaphezulu kwe-HRC65, ukunyusa ukuxhathisa ukunxiba ngamaxesha angama-2-4.

Uphawu kunye nesicelo

1. Ukuhanjiswa kwezinto eziphathekayo: Ukunyanzeliswa kunye noZinzile, Akukho ukubuyela ngasemva

Isakhiwo se-intermeshing sidala "igumbi lezinto eziphathekayo" elivaliweyo elityhala ngenkani izinto eziphathekayo, ukuphelisa ngokupheleleyo ingxaki yokubuyela umva ehambelana ne-low-meshing okanye i-non-meshing screws.

Ukuhanjiswa ngokufanelekileyo akuchatshazelwa kakhulu yi-viscosity yezinto. Nangona uphatha izinto ezibonakalayo ezifana neeplastiki ezityhidiweyo kunye ne-slurries egxininiswe kakhulu, izinga lokutya elizinzileyo linokugcinwa, liqinisekisa imveliso eqhubekayo.

2. Ukuxuba kunye nokucheba: Impembelelo eyomeleleyo, i-uniform ephezulu

Xa izikrufu ezibini zidibanisa i-intermesh, zenza isenzo esiphindwe kathathu "sokucheba," "ukuxova," kunye "nokuwa" kwizinto eziphathekayo, ngokukhawuleza ukuphula i-agglomerates yezinto kunye nokuphumeza ukuxubana okufanayo kwe-microscopically yamacandelo.

Esi sikhundla sinamandla sokucheba sikwanceda ukunyibilika okanye ukusabela. Ngokomzekelo, kwi-extrusion yeplastiki, inokunciphisa ixesha lokunyibilika kwaye ifezekise umgangatho ofanayo wokunyibilika.

3. Uxinzelelo kunye noBushushu: Ukulawulwa kakhulu, ukulungele ukusebenza koxinzelelo oluphezulu

Igumbi elivaliweyo liseka ngokufanelekileyo kwaye ligcina uxinzelelo oluzinzileyo olusebenzayo, okwenza ukuba lilungele iinkqubo ezifuna uxinzelelo, njengoxinzelelo lwesayizi kwi-extrusion yombhobho weplastiki kunye neempendulo ezixinzelelekileyo zezinto ezisebenzayo. Ixesha lokuhlala lemathiriyeli ngaphakathi kwegumbi elivaliweyo liyahambelana noko, kwaye ukutshintshiselana kobushushu phakathi kwesikrufu kunye nomgqomo kufana kakhulu, okwenza ulawulo oluchanekileyo lobushushu bezinto kunye nokuthintela ukufudumeza kwendawo okanye ukungalingani kobushushu obunokukhokelela ekuwohlokeni kwezinto.

4. Umda weSicelo: Izisombululo ekuJoliswe kuzo kwiiMfuno zoLungiso olunzima

Oku kulungele ngokukhethekileyo izinto ezine-viscosity ephezulu, i-elasticity ephezulu, kwaye ifuna ukuxuba okulungileyo, okufana neeplastiki, irabha, i-adhesives, kunye ne-concentration coatings ephezulu.

Xa kuthelekiswa nezinye izikrufu, i-Nanhaiya's intermeshing conical-screws inciphisa intsalela yezinto ngaphakathi kwesixhobo, ukwenza lula ukucoca ngexesha lokutshintsha kwezinto kunye nokuphucula ngokungathanga ngqo ukusebenza kakuhle kwemveliso.

 Ezona ndawo ziphambili zokusetyenziswa kwe-intermeshing conical twin-screw extruders zigubungela phantse onke amanyathelo abalulekileyo kwinkqubo yokusetyenzwa kweeplastiki, ukusuka kwimathiriyeli ekrwada ukuya kwiimveliso ezigqityiweyo.

1. I-Plastiki Extrusion: Isetyenziselwa ukuveliswa kwemibhobho, iiprofayili (ezifana neminyango kunye neefestile zefestile), amashidi, iifilimu, i-cable coverings, kunye nokunye. Umthamo wayo ophezulu wokuhambisa uqinisekisa ukuhamba okuzinzileyo kweplastiki yokunyibilika, ngelixa isiphumo sayo esinamandla sokucheba sivumela ukuxuba ngokucokisekileyo kweplastiki kunye nezongezo (ezifana ne-masterbatches kunye ne-antioxidants), ukuqinisekisa umgangatho ofanayo kwimveliso egqityiweyo.

2. I-Plastiki yeGranulation: Iiplastiki zeplastiki, izinto ezisetyenzisiweyo, okanye izinto ezintsha ziyanyibilika, zikhutshwe, kwaye zisikwe kwiipellets ngokusebenzisa isikrufu. Isakhiwo se-intermeshing siqinisekisa ukunyibilika ngokucokisekileyo kunye neplastiki yeplastiki, ukuthintela izibonda ezinganyibilikiyo kwiipellets.

3. Ukucutshungulwa kwePlastiki eKhethekileyo: Ukucubungula iiplastiki ezinokushisa okuphezulu kunye neemfuno zokuxuba, ezifana ne-PVC (i-polyvinyl chloride) kunye ne-PC (i-polycarbonate). Ulawulo lwayo oluchanekileyo lweqondo lokushisa luthintela i-PVC ukuba ingaboli kwiqondo lokushisa eliphezulu, ngelixa ukuxuba kwayo okufanayo kuqinisekisa iipropati ezizinzileyo zemishini yeemveliso zePC.

Iinkcukacha

Ukucocwa okufanelekileyo kudala "indawo yokutywina" ngexesha lomsebenzi wokujikijelwa, ukunciphisa ukubuya umva kwezixhobo ze-viscosity ephezulu ukuya ekupheleni kwesondlo phantsi koxinzelelo kunye nokuqinisekisa ukuhanjiswa okunyanzelekileyo okusebenzayo. Oku kubaluleke kakhulu kwi-intermeshing conical twin-screw extruders. I-Nanhai Ya ilawula ngokungqongqo ukukhutshwa phakathi kwamazinyo amabini angama-screw, usebenzisa i-high-precision machining (efana nokusila) ukuqinisekisa ukucoceka okufanayo.

Ubushushu obuphezulu, ukuchaneka komatshini, kunye neenkqubo ze-nitriding ziqinisekisa ukusebenza okubanzi kwamacandelo aphambili.

Iindawo ezinobungozi ze-screw kunye ne-barrel ziqiniswa nge-alloy ye-nickel-tungsten alloy layer, ukufikelela kwi-2-3mm umaleko obunzima kunye nokuphucula kakhulu ukuxhathisa ukunxiba.
