2,Standard test Force (Qib 8)

Qib 1: 0.325kg = (piston pas nrig + qhov hnyav lub tais + lub tes tsho thaum tshav kub kub + tsis muaj 1 lub cev hnyav)

= 3.187 TZS

Qib 2: 1.200kg =(0.325+ No.2 0.875 nyhav) = 11.77N

Qib 3: 2.160kg =(0.325+ No.3 1.835 nyhav) = 21.18N

Qib 4: 3.800 kg = (0.325 + no.4 3.475 yuag) = 37.26N

Qib 5: 5,000 kg = (0.325 + no.5 4.675 yuag) = 49.03N

Qib 6: 10.000 kg = (0.325 + No.5 4.675 yuag + No.6 5.000 nyhav) = 98.07N

Qib 7: 12.000 kg=(0.325+ no.5 4.675 luj + No.6 5.000+ No.7 2.500 nyhav)= 122.58N

Qib 8: 21.600 kg=(0.325+ tus lej 2 0.875 hnyav + Number 3 1.835+ Number 4

3.475+5 4.675+6 5.000+7 2.500+8 2.915 luj) = 211.82N

kwv tij yuam kev ntawm qhov hnyav≤0.5%.

3,Qhov kub thiab txias:50-300℃

4,Qhov kub thiab txias precision: ±0.5℃.

5,Fais fab mov:220 V±10% 50Hz

6,Ua haujlwm ib puag ncig: ambient kub yog 10℃-40℃;Cov av noo ntawm ib puag ncig yog 30% -80%;Tsis muaj corrosive nruab nrab ib ncig, tsis muaj zog cua convection;Tsis muaj kev vibration thiab muaj zog magnetic teb cuam tshuam ib puag ncig.

7,Ntsuas qhov ntev:250×350×600 = ib(L×W×H)

Lub hauv paus ntsiab lus thiab kev ua haujlwm:

Melt flow rate meter yog extruded yas meter.Nws yog nyob rau hauv cov xwm txheej kub uas tau teev tseg, nrog rau qhov kub thiab txias cua sov ua kom cov khoom ntsuas kom ua tiav lub xeev melting.Lub xeev molten ntawm cov khoom ntsuas, nyob rau hauv lub cev hnyav load lub ntiajteb txawj nqus los ntawm ib tug tej txoj kab uas hla ntawm lub qhov extrusion xeem.Hauv kev tsim cov khoom lag luam plastics thiab kev tshawb fawb ntawm cov chaw tshawb fawb tshawb fawb, "melt (mass) flow rate" feem ntau yog siv los qhia txog cov dej ntws, viscosity thiab lwm yam khoom ntawm lub cev ntawm cov ntaub ntawv polymer hauv lub xeev melting.Lub npe hu ua melting index yog hais txog qhov hnyav nruab nrab ntawm txhua ntu ntawm cov qauv extruded rau hauv 10 feeb ntawm extrusion.

Melt (mas) flow rate meter yog qhia los ntawm MFR, chav tsev yog: g / 10 min (g / min) Formula: MFR (θ, npe)                      = tref .m/t

Hauv cov qauv: θ—Ntsuas kub

          mnom—Nominal load Kg

           m ——Qhov nruab nrab loj ntawm qhov txiav g

          tref——Siv sijhawm(10 feeb), S (600s)

           t——Lub sijhawm luv rau kev txiav s

Lub ntsuas hluav taws xob yog tsim los ntawm cov cua kub cua sov thiab qhov ntsuas kub thiab nruab rau ntawm lub fuselage (kem) puag.

Kev tswj qhov kub thiab txias tau txais ib-chip microcomputer los kho lub zog thiab tswj qhov kub thiab txias, uas muaj peev xwm tiv thaiv kev cuam tshuam, siab kub tswj precision thiab ruaj khov.Cov cua sov hlau nyob rau hauv lub cub tawg yog qhov txhab ntawm lub cua sov pas nrig raws li ib qho kev cai lij choj kom txo tau qhov kub thiab txias gradient thiab ua tau raws li tus qauv yuav tsum tau ua.

Cov teeb meem xav tau kev saib xyuas:

1,Ib lub qhov hluav taws xob ib leeg yuav tsum muaj lub qhov hluav taws xob hauv av, thiab txhim khu kev qha hauv av.

2,Yog tias muaj qhov txawv txav ntawm lub LCD, nws yuav tsum raug kaw ua ntej, thiab rov pib dua qhov ntsuas kub thiab pib ua haujlwm.

3,Hauv kev ua haujlwm ib txwm, yog tias qhov cub kub kub ntau dua 300℃, software tiv thaiv, cua sov cuam tshuam, thiab tswb.

4,Yog tias muaj qhov tshwm sim txawv txav, xws li kev tswj qhov kub thiab txias, tsis tuaj yeem tso saib, thiab lwm yam, yuav tsum raug kaw rau kev saib xyuas,

5,Thaum ntxuav lub piston pas nrig, tsis txhob txhuam nrog cov khoom tawv.
