Bafa Yosinthira Kutentha kwa Liwiro la PR533

Chidule

PR533 imagwiritsidwa ntchito potsimikizira, kulinganiza ndi kuyesa zida ndi zida zoyezera kutentha ndi zowongolera, monga chowongolera kutentha ndi magetsi, chosinthira kutentha, ndi zina zotero. Ndi yoyenera kwambiri polinganiza "ma thermostat a pamwamba pa mafuta osinthika" ndi "ma thermostat a pamwamba osinthika". Nthawi zambiri kutentha kwa bafa kumakhala pa (0-160) °C, ndipo kutentha kumatha kusinthidwa pamlingo wofunikira. Ndipo bafa ilinso ndi ntchito yokhazikika ya kutentha. Nthawi yake yokhazikika ya kutentha nthawi zambiri imatchulidwa kuti 1 °C / min ndipo nthawi yake yozizira nthawi zambiri imatchulidwa kuti - 1 ° C / min.

Kupatula kukhala ndi ntchito yotenthetsera kutentha kwa bafa yamadzimadzi, PR533 imatha kutenthetsa ndi kuziziritsa mwachangu malinga ndi kuchuluka kwa kutentha ndi kuziziritsa komwe kwakhazikitsidwa. Kudzera mu kapangidwe kapadera ka makina oziziritsira, imatha kuwongolera kutentha kwa bafa kuti kuziziritse mosalekeza malinga ndi kuchuluka kwa kuziziritsa komwe kwakhazikitsidwa pamlingo wokulirapo (monga 160 ℃ ~ 0 ℃), ndipo imalola kukhazikitsa malo otentha pakati. Imatha kuchita molondola, mwachangu komanso mosavuta ndikuyesa kuchuluka kwa kutentha ndi kusiyana kwa malo olumikizirana ndi magetsi a chipangizo chotenthetsera. Kuchuluka kwa kusintha (mtengo wokwanira) kwa kutentha kwa bafa ndi 1 ℃/min, ndipo imatha kusinthidwa.

Mawonekedwe

1. Imathetsa vuto la kuwongolera kutentha ndi kuzizira mu calibration: ndi sikelo yonse ya 0 ~ 160 °C, imatha kupangitsa kutentha ndi kuzizira kukhala kosinthasintha, ndipo kutentha ndi kuzizira kumatha kukhazikitsidwa (kutentha ndi kuzizira kumatha kukhazikitsidwa: 0.7 ~ 1.2 °C/min). Ma thermostat okwana asanu ndi limodzi amatha kuyesedwa nthawi imodzi, zomwe zimapangitsa kuti ntchito ikhale yogwira ntchito bwino m'njira yonse.

2. Ndi mapulogalamu apadera, imatha kuzindikira mwanzeru momwe kutentha ndi kuzizira zimakhalira nthawi zonse / mwachangu kuti zigwire bwino ntchito: Pamene mtengo wosonyeza ndi cholakwika cha kukhudzana zimayesedwa nthawi imodzi, njira yotenthetsera ndi kuziziritsa kutentha ikhoza kukhazikitsidwa malinga ndi kutentha komwe kumayikidwa komanso kutentha kwa magetsi panthawi yonse yoyezera. Ndipo kutentha komwe kumaphatikizapo kulumikizana ndi magetsi kudzagwiritsa ntchito njira yotenthetsera ndi kuziziritsa mwachangu, ndipo kutentha komwe sikunagwiritsidwe ntchito ndi magetsi kudzagwiritsa ntchito njira yotenthetsera ndi kuziziritsa mwachangu, zomwe zingathandize bwino kukonza bwino.

3. Kukwaniritsa kufunikira kwachangu kwa zenizeni, kukwaniritsa kuziziritsa liwiro kosalekeza: Chogulitsachi chimapangidwa kutengera zosowa za mafakitale, monga kutumiza mphamvu ndi kusintha, metrology ndi calibration. Ndipo chakudya chamasana cha chinthuchi chingathandize kwambiri kuzindikira ndi kuwerengera bwino komanso mulingo wa zida zokhudzana nazo m'mafakitale omwe ali pamwambapa. Ndipo chimakonza ndikusintha algorithm, yomwe ingayang'ane kwambiri kuziziritsa liwiro kosalekeza, kutumiza algorithm yosinthira malinga ndi chitsanzo chosinthira kutentha, kugwirizana ndi algorithm yakale ya PID, ndikugwiritsa ntchito ukadaulo wapamwamba wa DC frequency conversion speed regulation kuti zitsimikizire kuti kutentha ndi kuziziritsa liwiro kosalekeza kukugwira ntchito bwino komanso kodalirika.

4. Kupanga njira yatsopano yoziziritsira ndi kupangitsa kuti dongosolo likhale losavuta: Kuziziritsa kwa compressor m'bafa kumagwiritsa ntchito njira yatsopano komanso njira ya "one drive two", yomwe imapangitsa kuti dongosololi likhale losavuta komanso kudalirika komanso kukwaniritsa zofunikira pa ntchito.

5. Kutentha ndi kuziziritsa kwa mbali imodzi, kutsatira miyezo ya akatswiri: Mu gawo lokwera la kuwerengera, liwiro lokhazikika limatsimikizira kuti kutentha kwa thanki kumakwera mosasinthasintha, ndipo kutsika kwa nthawi yochepa kwa kutentha kwa thanki kumatha kupewedwa bwino ngakhale mu gawo lokhazikika la kukwera kwa mbali imodzi; momwemonso, mu gawo lotsika la kuwerengera, thanki yotsimikizika imatsimikizika. Kutentha kumachepa mbali imodzi, ndipo kukwera kwa nthawi yochepa kwa kutentha kwa thanki kumatha kupewedwa bwino ngakhale mu gawo lokhazikika la kutsika kwa mbali imodzi kuti zitsimikizire kuti deta yoyezera ndi yowona komanso yodalirika.

6. Kupukuta mapaipi okha, kuchepetsa kukonza: Pakuzizira mwachangu komanso kutentha kwa bafa kukukwaniritsa zofunikira zomwe zafotokozedwa, mapampu onse omwe ali mu dera loziziritsira la media amasinthidwa kuti ayeretsedwe okha.

7. Malumikizidwe awiri olumikizirana: Bafa losinthasintha la PR533 limapereka maulumikizidwe akunja a RS-232 ndi RS-485. Malumikizidwe awiriwa olumikizirana ali ndi njira yolumikizirana yokhazikika, yomwe ingagwiritsidwe ntchito ngati kulumikizana pakati pa kompyuta ndi konsolo yakomweko.
