Kev Cai Ntau Lawm Ntawm Ntxig Hom Radiator

1. Rau qhov ntom ntom ntawm cov hniav mus rau tus nplaig pwm, thawj tus pas nrig txhuas yuav tsum yog tus pas nrig luv lossis txhuas txhuas ntshiab ntawm 150-200mm.

2. Ua ntej sim ua pwm, qhov chaw extrusion yuav tsum tau hloov kho kom lub hau ntswj extrusion, lub tog raj nkag thiab lub qhov hluav taws xob ntawm lub hauv paus pwm yog nyob hauv kab ib kab.

3. Thaum lub sijhawm sim pwm thiab tsim khoom ib txwm muaj, cua sov kub ntawm txhuas pas nrig yuav tsum nyob nruab nrab ntawm 480-520 ℃.

4. Cov cua sov kub ntawm pwm tuaj yeem tswj tau ntawm 480 ℃ raws li cov pwm kub ib txwm muaj. Lub sijhawm tiv thaiv tshav kub ntawm cov pwm tiaj nrog lub cheeb tsawg dua 200mm yuav tsum tsis pub tsawg tshaj 2 teev. Yog tias nws yog pwm sib cais, lub sijhawm khaws cia cua sov yuav tsum ntau dua 3 teev. Teev kom ntseeg tau tias qhov sib xws ntawm cov pwm kub thiab qhov kub sab nraud.

5. Ua ntej mus sib hais pwm lossis tsim khoom, lub thawv ntim sab hauv ntawm lub thawv ntim khoom yuav tsum tau muab ntxuav nrog lub tog raj kheej tu lub gasket, thiab xyuas seb puas qhuav qhuav ntawm lub tshuab extruder yog ib txwm muaj.

6. Thaum cov pwm tau sim lossis tsim tawm tsuas yog pib, lub iav tsis siv neeg ntawm lub tshuab extruder raug kaw, thiab cov hloov ntawm txhua ntu tau rov pib dua rau txoj haujlwm xoom. Pib maj mam los ntawm qhov siab tshaj plaws, thiab tso cov khoom rau li 3-5 feeb. Qhov siab feem ntau yog tswj thaum lub sijhawm ua cov txheej txheem txhuas. Lub siab raug tswj tsis pub dhau 100Kg/cm2, cov ntaub ntawv ammeter tsis pub dhau 2-3A, feem ntau 80-120Kg/cm2 tuaj yeem tso tawm, thiab tom qab ntawd nws tuaj yeem maj nrawm. Thaum lub sijhawm tsim khoom ib txwm muaj, qhov nrawm nrawm yuav raug rau siab dua 120Kg/cm2.

7. Thaum lub sijhawm sim pwm lossis txheej txheem tsim khoom, yog tias cov pwm raug thaiv, cov hniav ib nrab, qhov sib txawv nrawm yog loj dhau, thiab lwm yam, cov pwm yuav tsum raug tso tseg tam sim ntawd, thiab cov pwm yuav tsum raug tshem tawm hauv txoj hauv kev rov qab los zam qhov pwm raug muab pov tseg.

8. Hauv kev sim lossis txheej txheem tsim khoom, qhov chaw tso tawm yuav tsum tsis muaj kev cuam tshuam, thiab lub tog hauv ncoo txhawb nqa lossis clamp slack yuav tsum muaj kev tswj hwm raws li qhov xwm txheej tso tawm. Soj ntsuam thiab pom cov xwm txheej txawv txav txhua lub sijhawm thiab daws nrog lawv nyob rau lub sijhawm. Thaum kaw qhov tshwm sim, lub tshuab yuav tsum raug kaw tam sim ntawd.

9. Thaum lub sijhawm ua haujlwm ncaj, nws yog qhov yuav tsum tau ua tib zoo tshuaj xyuas cov kev hloov ua ntej thiab tom qab, ua haujlwm raws li tus qauv, siv quab yuam me ntsis, thiab nruj me ntsis kom ntseeg tau cov khoom zoo.

10. Teeb qhov ntev kom tsim nyog raws li qhov yuav tsum tau ua ntawm cov phiaj xwm tsim khoom. Thaum pom, pom cov hniav noj ceev yuav tsum tsis txhob nrawm dhau kom tsis txhob puas rau qhov kawg. Qhov kawg yuav tsum tau clamped kom tshem tawm cov nyem thiab burrs.

11. Kev teeb tsa lub pob tawb yuav tsum tau ua tus qauv, suav nrog lub ncoo hauv ncoo yuav tsum tau muab tso kom tsim nyog kom tsis txhob puas rau qhov profile.

12. Lub hnub nyoog kub ntawm qhov profile raug tswj ntawm 190 ± 5 ℃, qhov kub tau khaws cia rau 2.5-4 teev, thiab nws tau cua txias tom qab tawm hauv lub cub tawg.
