I-extruder yinxalenye ebalulekileyo yesixhobo sokubumba iplastiki kunye ne-pelletizing. Ukusetyenziswa kwemihla ngemihla kwe-extruder kunokunika umdlalo opheleleyo ekusebenzeni komatshini kunye nokugcina imeko yokusebenza ebalaseleyo. Kufuneka igcinwe ngononophelo ngokungapheziyo ukwandisa ubomi benkonzo yesixhobo. Ukusilela okuphambili kwe-extruder yingxolo engaqhelekanga kunye nokungcangcazela okungaqhelekanga okubangelwa kukunxitywa okungaqhelekanga, ukuguga okanye ukonakaliswa kweendawo zothumelo, kunye nokungathobi ngokwaneleyo.

Iimpazamo eziqhelekileyo zeplastiki ye-extruder:
1. Umamkeli wangoku akazinzanga
Izizathu zemveliso:
● Ukutya okungalinganiyo.
● Eyona nto iphambili yemoto yonakele okanye ayicolisi kakuhle.
● Icandelo elithile lesifudumezi liyasilela kwaye alitshisi.
● I-screw adjustment pad ayilunganga, okanye isigaba siyoyikeka, kwaye izinto ziyaphazamisa.

Indlela:

● I-induction current ye-inverter ayizange ikhutshwe. Cima umbane oyintloko kwaye ulinde imizuzu emi-5 ngaphambi kokuba uqale.
● Jonga ukuba iqhosha likaxakeka lisetyenzisiwe na.

3.Intloko yomatshini ayigudi okanye ivalwe
Isizathu:
● Icandelo elithile lesifudumezi alisebenzi, kwaye iplastiki yemathiriyeli ikwimeko embi.
● Ubushushu bokusebenza bubekwe phantsi kakhulu, okanye ulwabiwo lweplastiki lobunzima bemolekyuli lubanzi kwaye aluzinzanga.
● Kusenokubakho izinto zasemzini ekungelula ukuba zinyibilike.
Indlela:
● Qwalasela isifudumezi uze usitshintshe ukuba kuyimfuneko.
● Qinisekisa ubushushu obumiselweyo becandelo ngalinye, thethana negcisa ukuba kukho imfuneko, kwaye unyuse ixabiso lokumisela iqondo lobushushu.
● Coca kwaye ukhangele inkqubo ye-extrusion kunye nentloko yomatshini.

4. Isiqalo sokuqala siphezulu kakhulu
Isizathu:
● Ixesha lokufudumala alanelanga, kwaye i-torque yanele.
● Icandelo elithile le-heater alisebenzi.
Indlela:
● Ngaphambi kokuba uqhube, sebenzisa ivili lesandla. Ukuba akukho lula, yandisa ixesha lokufudumeza okanye khangela ukuba icandelo ngalinye lesifudumezi lisebenza yonke imihla.

5. Injini engundoqo yenza isandi esingaqhelekanga
Isizathu:

● Khangela i-thyristor rectifier circuit, kwaye ubeke indawo ye-thyristor element ukuba kuyimfuneko.

I-6.Eyona nto iphambili yokunyuka kweqondo lobushushu iphezulu kakhulu
Isizathu:
● Ukuthanjiswa kakubi.
● Ukuthwala kugugile kakhulu.
Indlela:
● Jonga uze wongeze isithambiso. Qwalasela iibheringi zeemoto uze uzibuyisele xa kukho imfuneko.

7.Uxinzelelo lwentloko aluzinzanga
Isizathu:
● Isantya sokujikeleza semoto ephambili ayilingani.
● Isantya senjini yokutyisa siyaguquguquka, kwaye isixa sokutya siyaguquguquka.
Indlela:
● Qwalasela isixokelelwano solawulo lweemoto esembindini kunye neebheringi.
● Qwalasela isixokelelwano somxhesho kunye nesixokelelwano solawulo.

8. Uxinzelelo lweoyile yokuthambisa ephantsi
Isizathu:
● Ixabiso lokumisela uxinzelelo lwevalve yokulawula uxinzelelo lwenkqubo ye-oyile iphantsi kakhulu.
● Impompo yeoli inengxaki, okanye umbhobho wokufunxa ioyile uvalekile.
Indlela:
● Jonga kwaye ulungise ivalve elawula uxinzelelo lwenkqubo yeoli yokuthambisa.
● Qwalasela impompo yeoli kunye nombhobho wokufunxa.

Ukuze ugweme ukungaphumeleli kunye nokugcinwa kwemihla ngemihla, ukugcinwa, kunye nokulungiswa ngokungqongqo ngokuhambelana neemfuno, kuyafuneka ukuba ubeke ingqalelo ekunxityweni kwe-screw extruder.
Ukunxiba okuqhelekileyo kwe-screw kunye ne-barrel ye-extruder yeplastiki kwenzeka ikakhulu kwindawo yokutya kunye nommandla wokulinganisa. Isizathu esiphambili sokugqoka kukungqubuzana okomileyo phakathi kweengqungquthela ze-chip kunye nentsimbi; xa i-chip itshisa kwaye ithambile, iyancipha.

esinye isikrufu esikhuphayo

Ukuguga okungaqhelekanga kwesikrufu kunye nomgqomo kuya kwenzeka xa i-screw lock ngamaqhina eringi kunye nezinto zangaphandle. Iqhina leringi lithetha ukuba imathiriyeli ejiyileyo itshixa isikrufu. Ukuba i-screw extruder ayinaso isixhobo esifanelekileyo sokukhusela, amandla okuqhuba anamandla angajija. Ukuba isikrufu sibambekile, siya kuvelisa ukuxhathisa okukhulu, kubangele umonakalo omkhulu kumphezulu wesikrufu kunye nemikrwelo eqatha kumbhobho.
Imikrwelo esemgqomeni inzima ukuyilungisa. Umgqomo wenzelwe umgaqo wokuqinisekisa ukuba ubomi benkonzo bude kunobu-screw. Ukugqoka umgqomo oqhelekileyo, ngokuqhelekileyo awulungiswanga. Indlela yokuphucula i-screw thread isoloko isetyenziselwa ukubuyisela i-gap ye-radial phakathi komngxuma wangaphakathi wombhobho kunye nobubanzi obungaphandle be-screw.

isisombululo:
Umonakalo wengingqi we-screw thread ukulungiswa ngokubeka i-welding ekhethekileyo yokuchasana nokunxiba kunye ne-alloy enganyangekiyo ku-corrosion. Ngokubanzi, ukuwelda kwegesi engasebenziyo, kunye ne-plasma argon i-welding, kwaye itekhnoloji yokutshiza isinyithi nayo ingasetyenziselwa ukulungiswa. Okokuqala, gaya umphezulu ongaphandle wesikrufu esigugileyo ukuya kubunzulu obumalunga ne-1.5mm, emva koko ugqume umaleko we-alloyi ukuya kubungakanani obaneleyo ukuqinisekisa isibonelelo esaneleyo somatshini, kwaye ekugqibeleni ugaye isangqa sangaphandle sesikrufu kunye necala lesikrufu ukuya kubungakanani bokuqala bobukhulu be-screw.

Ingxolo engaqhelekanga
● Ukuba iyenzeka kwisinciphisi, inokubangelwa kukuthwala umonakalo okanye ukuthamba okungonelanga okanye okubangelwa kukuguga kwezixhobo, ukufakela ngokungafanelekanga, kunye nokulungelelaniswa, okanye ukungaxutywa kakuhle kwezixhobo. Inokusombulula ngokutshintsha iibheringi, ukuphucula ukuthambisa, ukutshintsha iigiya, okanye ukulungelelanisa iimeko zokudibanisa izixhobo.
● Ukuba ingxolo sisandi esibukhali sokukhuhla, qwalasela ukuba nokwenzeka kwentloko ye-shaft kunye ne-sleeve shaft sleeve scraping ngenxa yokuphambuka kwendawo yombhobho. Inokusombulula ngokulungisa umgqomo.
● Ukuba umphanda wenza ingxolo, inokuba kungenxa yokuba isikrufu sigotywe ukutshayela ibhore okanye iqondo lobushushu elibekiweyo liphantsi kakhulu, libangela ukukhuhlana okugqithisileyo kwamasuntswana aqinileyo. Inokucutshungulwa ngokulungisa isikrufu okanye ukwandisa ubushushu obumiselweyo.

Ukungcangcazela okungaqhelekanga
Ukuba oku kwenzeka kwi-reducer, kubangelwa ukugqoka kweebherethi kunye neegesi, ezinokusombululwa ngokutshintshela iibhondi okanye iinqwelo. Ukuba kwenzeka kwi-barrel, kungenxa yezinto eziyinkimbinkimbi zangaphandle ezixutywe kwizinto eziphathekayo, kwaye ukucoceka kwezinto kufuneka kuhlolwe. Ukuba kukho imfuneko, fakela isixhobo esiluqilima esizibuthe kwi-hopper ukubhengeza iifayili zentsimbi.

Ukuvaleka kwe-annular kwi-screw inlet
Oku kusilela kubangelwa ikakhulu kukuphazamiseka kwamanzi okupholisa okanye ukuhamba okungonelanga. Inkqubo yokupholisa kufuneka ihlolwe, kwaye ukuhamba kunye noxinzelelo lwamanzi okupholisa kufuneka ulungelelanise kwiimfuno ezichaziweyo. Kusenokwenzeka ukuba isiqwenga esikhulu semathiriyeli esetyenzisiweyo kwimathiriyeli ekrwada ivalela indawo yokungena kwaye ifuna ukucocwa. Isingeniso.
Oku kungasentla luhlalutyo oluqhelekileyo lokungaphumeleli kunye nezisombululo zeplastiki ze-extruder. Jonga ukuba uyifundile na?
