Qodobka 1: Horudhaca dhibaatooyinka caadiga ah ee hoos u dhaca inta lagu jiro habka extruder-ka ee ka saarista:
In wax soo saarka extrusion ee profiles aluminium, cilladaha sida caadiga ah loo yaqaan yaraynta ka muuqan doona in alaabta semi-dhammeeyay ka dib markii la gooyo madaxa iyo dabada ka dib markii alkali etching kormeerka. Qalabka farsamada ee aluminium profiles ka kooban qaab-dhismeedkani ma buuxinayo shuruudaha, oo keenaya khataro badbaado.
Isla mar ahaantaana, marka la soo saaro aluminium aluminium aluminium profiles ayaa lagu daaweeyaa dusha sare ama hagaajinta, jiritaanka cilladani waxay burburisaa sii wadida gudaha ee walxaha, taas oo saameyn doonta dusha dambe iyo dhamaystirka. Xaaladaha halista ah, waxay keeni doontaa in calaamadaha qarsoon la xoqo ama waxyeello u geystaan qalabka leexinta iyo khataraha kale, tani waa dhibaatada caadiga ah ee wax soo saarka. Halkan, maqaalkani wuxuu si kooban u falanqeynayaa sababaha abuuritaanka aluminium profile yaraanta iyo hababka loo tirtiro.
Dhibicda 2: Kala soocida hoos u dhaca muuqaalada aluminiumka ee extruders: hoos u dhaca godan iyo hoos u dhaca sanadlaha ah:
1) Hoos u dhac madhan: A godan ayaa laga sameeyay bartamaha dabada ee profiles extruded iyo baararka. Qaybta iskutallaabtu waxay u muuqataa sida dalool leh geeso qallafsan ama dalool leh geeso ay ka buuxaan wasakh kale. Jihada dhererka waa koofiyad qaabeysan funnel, caarada maroodiga waxay wajaheysaa jihada socodka birta. Waxay inta badan ku dhacdaa in diyaarad hal-dalool dhiman extrusion, gaar ahaan dabada profiles extruded la coefficients extrusion yar, dhexroor alaabta waaweyn, derbiyada qaro weyn, ama gaskets extrusion saliid-wasab.
2) Yaraanta sanadlaha ah: Labada daraf ee sheyga shunt shunt ah ee wax soo saarka ah, gaar ahaan madaxa, waa faraanti la joojiyay ama geeso, iyo qaabka bilaha ayaa aad uga muuqda labada dhinac ee xariiqda alxanka. Yaraynta sanadlaha ah ee badeecad kasta oo dalool ah waa mid siman.
Sababta keentay dhimista: Xaaladda farsamada ee samaynta dhimista ayaa ah in marka marxaladda advection ay dhammaato oo gaaska extrusion si tartiib tartiib ah u soo dhawaado dhimashada, extrusionku wuu kordhaa oo wuxuu abuuraa cadaadis dN oo ku yaal dusha dhinaca ee foosto extrusion. Xooggan oo ay weheliyaan xoogga isku-dhafka dT cylinder, marka xaaladda dheelitirka xoogga dN cylinder ≥ dT pad la burburiyo, birta ku taal agagaarka aagga gaasaska la sii daayay ayaa gadaal u qulqulaya cidhifka dhexda bannaan, sameynta hoos u dhac.
Qodobka 3: Waa maxay xaaladaha extrusion ee keena hoos u dhigista dabada:
1. Walxaha haraaga ah ee soo saarista aad bay u gaaban yihiin
2. Gaaska extrusion waa saliid ama wasakh
3. Dusha sare ee gogosha ama dhogorta ma nadiifsana
4. Dhererka goynta alaabtu ma waafaqsana xeerarka
5. Dahaarka dhululubada extrusion waa mid aan loo dulqaadan karin
6. Xawaaraha extrusion ayaa si lama filaan ah u kordha.
Qodobka 4: Hababka lagu baabi'inayo yaraynta ay sameeyeen mashiinnada extrusion aluminium iyo tallaabooyinka lagu dhimayo loogana hortagayo samaynta dhimista:
1. Si adag u raac xeerarka nidaamka si aad u gooyso oo aad u cadaadiso xad-dhaafka, arkay madaxa iyo dabada, sii dahaarka dhululubada extrusion si sax ah, mamnuuc gaaska saliidda, hoos u dhig heerkulka usha aluminium ka hor intaan la saarin, oo isticmaal gaasaska convex gaar ah. Dooro dherer macquul ah oo walxaha hadhaaga ah.
2. Dusha sare ee qalabka extrusion iyo ulaha aluminium waa inay nadiif ahaadaan
3. Si joogto ah u hubi cabbirka dhululubada extrusion oo beddel qalabka aan u qalmin
4. Diidmada jilicsan, xawaaraha extrusion waa in hoos loo dhigaa marxaladda dambe ee extrusion, iyo dhumucda soo hadhay waa in si habboon looga tago, ama habka extrusion ee kordhinta walxaha haraaga ah waa in la isticmaalo.
Qodobka 5: Si wax ku ool ah loo baabi'iyo ifafaale hoos u dhaca inta lagu guda jiro wax soo saarka ee mashiinada extrusion profile aluminium, dhumucda xad-dhaaf ah ee extruder sidoo kale loo baahan yahay in fiiro gaar ah. Kuwa soo socda waa heerka tixraaca ee dhumucda xad-dhaafka ah:
tonnage Extruder (T) dhumucdiisuna waxay tahay (mm)
800T ≥15mm 800-1000T ≥18mm
1200T ≥20mm 1600T ≥25mm
2500T ≥30mm 4000T ≥45mm
