Tsim ntawm Electroplating Kub ntsuas Circuit Court rau hluav taws xob cua sov raj

Tsim ntawm Electroplating Kub ntsuas Circuit Court rau hluav taws xob cua sov raj

Qhov kub yuav tsum tau rau electroplating ntau lawm yog nyob nruab nrab ntawm 40 degree thiab 70 degree, thiab input voltage ntawm lub -3A analog function module FXON yuav tsum nyob nruab nrab ntawm 0 thiab 10V. Yog li ntawd, qhov ntsuas kub ntawm qhov ntsuas kub ntsuas hluav taws xob siv hauv qhov tsim no yog 0 txog 100 degree, thiab qhov tso tawm qhov sib txawv voltage ntau yog 0 txog 5V. Qhov ntsuas kub ntsuas Circuit Court daim duab qhia hauv daim duab 2.

Ntawm lawv, Rt yog lub thermistor nrog qhov ntsuas kub zoo, qauv T{{0}}, thiab nws qhov ntsuas kub yog nyob nruab nrab ntawm -55 thiab 150, nrog rau qhov kub thiab txias coefficient ntawm 0.75 feem pua ​​/ K . Lub linearity yog qhov zoo, thiab qhov ntsuas qhov ntsuas kub tsis zoo tsis ntau tshaj ± 2.5 feem pua ​​​​hauv thaj tsam ntawm 0-100 degree . Lub Circuit Court muaj peb ntu: lub hwj huam mov, tus choj ntsuas qhov kub thiab txias, thiab lub amplifier. Txhawm rau kom tsis txhob muaj qhov cuam tshuam thermal ntawm tam sim no ntawm kev ntsuas qhov tseeb, qhov ua haujlwm tam sim no ntawm Rt raug xaiv kom qis dua 1mA, thiab nws yog siv los ntawm D1 voltage regulator. Tom qab ntawd, nws muab faib los ntawm R3 thiab semi adjustable resistor R5 los kho R5 thiaj li hais tias qhov voltage follower A1 outputs ib tug ua hauj lwm voltage ntawm R42.5V. LED ua hauj lwm raws li lub hwj huam mov qhia lub teeb, thiab R6, R7, thiab R8 tsim qhov ntsuas kub ntsuas choj Rt Circuit Court. Rt hloov qhov kub hloov pauv mus rau qhov hloov pauv hloov thiab tau txais qhov hloov pauv voltage. Nws cov zis yog amplified los ntawm A2 txawv amplification. Thaum qhov kub hloov pauv tsis pub dhau 0-100 degree, qhov sib thooj Vo tso zis voltage hloov nyob rau hauv 0-5V, nrog rhiab heev ntawm 50mV / degree . Yog xav tau qhov ntsuas kub kom raug ntau dua, cov thermocouples tuaj yeem siv tau.

2.3 Kev Tsim Kho thiab Cov Lus Ceeb Toom [3]

Vim tias qhov kev tswj hwm ntawm lub tank kub yog tib yam, tsab xov xwm no yuav siv qhov kev tswj hwm rau lub tank tooj liab plating ua piv txwv. Qhov kev pab cuam no tsuas yog siv rau kev siv xwb, thiab kev hloov kho tsim nyog yuav tsum tau ua yog tias nws yuav tsum tau siv rau hauv kev siv tswv yim. Raws li pom hauv daim duab 3.
