Ngesikhathi senqubo yokukhipha ipayipi, igesi idinga ukuphuma ekuncibilikeni. Uma la magesi engakwazi ukuphumela ngesikhathi, izici ezinjengama-pores, amabhamuza, nobuthuntu obungaphezulu kungase kuvele phezulu noma ngaphakathi kwemikhiqizo yamapayipi, kuthinte kabi izakhiwo zenyama nemishini, izakhiwo zamakhemikhali, kanye nepayipi lezakhiwo zikagesi.
Kukhona ama-vents angu-1 ukuya kwangu-2 phakathi kwembobo yokuphakela kanye nekhanda lomshini ukuze kukhishwe umswakama nokunye okuguquguqukayo kokuncibilikisiwe kwempahla. Kodwa-ke, ezinye izimbobo zamasilinda ensimbi zivame ukuvela. Inkinga evamile ukukhishwa kwempahla ku-exhaust port. Inani elincane lezinto lizothinta ukukhishwa kwe-volatile futhi lithinte ikhwalithi yomkhiqizo; inani elikhulu lezinto lizovimba imbobo yokukhipha umoya futhi libangele nokuphumula.
Ngokuvamile, kunezizathu ezimbili zokuphakela ipayipi extruder. Enye idizayini yesikulufu engenangqondo, ebangela ukuthi okokusebenza kugeleze kubuyele endaweni yokukhipha umoya; enye idizayini encane yechweba le-exhaust. Impahla encibilikisiwe “iyalengiswa” lapho idlula endaweni yokukhipha umoya.

Okokuqala, ungabona ukuthi izinto eziku-screw zigeleza zibuyela emuva zisuka ku-vent. Kuma-extruder amaningi angena umoya, ungabona ukuncibilika kuya phambili kusikulufu. Ngaphansi kwezimo ezijwayelekile, izinga lokugcwaliswa kwe-screw groove ngezinto alidluli ama-50%. Uma idlula, izothinta umphumela wokuqeda futhi ibangele ukuthi indwangu iveze embotsheni yokukhipha umoya; uma singaphansi kuka-50%, isikulufu singasebenza ngokujwayelekile. Okubalulekile okungekuhle kungase kubangelwe ukuklama okungenangqondo kwembobo yokukhipha umoya noma ingxenye ye-shunt.

Izinto Ezithinta Ukugwenywa Kwempahla Ye-Pipe Extruder kanye Nezixazululo

1. Isikulufa factor
Isikulufu se-exhaust sithatha idizayini enezigaba eziningi. Inzuzo yalo mklamo yukuthi i-port exhaust ingaphansi kwengcindezi evamile, futhi impahla ngeke iphume. I-extruder ene-vent eyodwa idinga isikulufu esiyisiteji esingu-2, nama-vents amabili adinga isikulufu esinezigaba ezi-3. Isiteji ngasinye sinesigaba sokucindezela okuphakathi, ingxenye yokucindezela, kanye nengxenye yokulinganisa. Isigaba sokuqala sesigaba sokuqala yisigaba sokudla okujwayelekile kwengcindezi, kanti isigaba sesibili yisigaba esivamile sokukhipha ingcindezi, okuyindawo lapho imbobo yokukhipha umoya itholakala khona.
Ngomklamo wesikulufu we-extruder ephumayo, kunezinkinga ezimbili: lapho impahla ifinyelela esigabeni sokukhipha umoya, impahla kumele incibilike ngokuphelele ukuze ikhiphe ama-volatile; okwesibili, inani lokuphakelayo lesikulufu sesigaba sesibili kufanele libe elibaluleke kakhulu kunalelo lesikulufu sesigaba sokuqala ukwenza I-screw groove ekuqaleni kwesigaba sesibili ayiphelele, ukuze i-outlet yomoya ikwazi ukugcina ingcindezi evamile.
Uma izinga lokuphakelayo lesikulufu sesigaba sokuqala libaluleke kakhulu kunesikulufu sesigaba sesibili, ukuncibilika ku-extruder kuzogeleza kubuyele emuva. Ukuxazulula le nkinga, kuyadingeka ukunciphisa inani lokudla lesigaba sokuqala noma ukwandisa inani lokudla lesigaba sesibili.

2. Izimo zenqubo
Indlela esheshayo nelula yokuxazulula inkinga ukushintsha izimo zenqubo. Isibonelo, ngikhulisa ukungqubuzana nengcindezi yokugunda kanye nesilinda noma isikulufu sensimbi futhi ngikhuphule ukungqubuzana noma i-viscosity endaweni yesilinda sensimbi ukuze ngithuthukise ivolomu yokulethwa.

3. I-Exhaust port
Uma isikulufu sembobo yokukhipha umoya sigcwaliswe kancane kuphela futhi imbobo yokukhipha umoya isasebenza, kunenkinga ethile ngedizayini yembobo yokukhipha umoya. Imbobo yokukhipha umoya kufanele ibe banzi kunomfudlana ogelezayo ukuze kuqinisekiswe ukuthi incibiliko ayivimbi imbobo yokukhipha umoya. Ngesikhathi esifanayo, ukuvulwa kwembobo yokukhipha umoya akufanele kube kukhulu kakhulu, okunganciphisa isikhathi sokuhlala sokuncibilika kanye nesikhathi sokunwetshwa kokugeleza kwezinto ezibonakalayo.
Njengomkhiqizi we-extruder wamapayipi, okuhlangenwe nakho kuka-Jinwei ukuthi: Ukuthi isikulufu esikhishwa umoya singaphandle kwento ehlobene ngokuqondile nenqubo yokukhipha, ukusebenza kwepulasitiki, kanye nedizayini yesikulufu nesikhala. Ngakho-ke, umenzi usebenzisa i-extruder ephuma umoya. Lapho ushiya umshini ukuze ukhiqize futhi ucutshungulwe, kuyadingeka ukuqonda ubuchwepheshe bokucubungula, izici ze-resin, nokusebenza kwemishini ukwenza i-extruder ephumayo ivamise ukusebenza futhi ngokuzinza.
