Esi sikhokelo sipheleleyo sihlola iindlela ezisebenzayo zokulawula isantya sokuhamba kwepompo yakho ye-peristaltic, ukusuka kulungiso olulula oluqhutywa ngesandla ukuya kwizisombululo ezizenzekelayo eziphambili.

Ukuqonda iziseko zoLawulo lokuhamba kwamanzi

Ngaphambi kokuba usebenzise iindlela zokulawula, kubalulekile ukuqonda ukuba yintoni emisela isantya sokuhamba kwamanzi kwimpompo ye-Mini peristaltic:

• 1,Isantya seMoto (RPM): I-primary control variable - isantya sokuhamba sihambelana ngqo nesantya sokujikeleza
• 2, Ububanzi bangaphakathi beTubing: Imisela ubungakanani obufudusiweyo ngokujikeleza ngakunye
• 3, Iipropati zolwelo: Ubunzulu kunye noxinano kuchaphazela ukusebenza kokuhamba kwamanzi okwenyani
• 4, Uxinzelelo lweNkqubo: Uxinzelelo oluvela kutshintsho lokuphakama okanye imiqathango luchaphazela imveliso

Iindlela eziphambili zokulawula izinga lokuhamba kwamanzi

Ulawulo lwesantya seMoto (Indlela eqhelekileyo)

Kwiimpompo ezisebenza ngeDC ezifana nempompo ye-peristaltic ye-12v, ulawulo lwesantya semoto lubonelela ngolungelelwaniso lokuhamba oluguquguqukayo noluchanekileyo:

• I-PWM (i-Pulse Width Modulation): Eyona ndlela isebenzayo yokulawula ipompo ye-Mini peristaltic
  • 1. Isebenzisa iipulses ezikhawulezayo zokuvula/ukucima ukuze inciphise ngempumelelo i-voltage ephakathi
  • 2. Igcina i-torque yemoto ngelixa isantya sayo sitshintshatshintsha
  • 3. Isetyenziswa ngokulula ngeArduino, iRaspberry Pi, okanye abalawuli bePWM abazinikeleyo.
• Ulawulo lweVoltage eguquguqukayo:
  • 1, iisekethe ezilula ezisekelwe kwi-potentiometer
  • 2, Abalawuli be-voltage ethe tye
  • 3. Ayisebenzi kakuhle kunePWM kodwa kulula ukuyisebenzisa.

Uhlengahlengiso lweMishini

• Ukukhetha iityhubhu: Ukutshintsha ububanzi bangaphakathi beetyhubhu kubonelela ngohlengahlengiso lokuhamba kwamanzi okurhabaxa
  • 1, i-ID enkulu = izinga lokuhamba eliphezulu kwi-RPM efanayo
  • 2, Isazisi Esincinci = izinga lokuhamba kwamanzi eliphantsi, ngcono xa kusenziwa idosi echanekileyo
• Uqwalaselo lweNtloko yeRoller: Ezinye iimpompo zivumela ukutshintsha inani leeroller
  • 3, Iirola ezingaphezulu zinciphisa ukubetha kwentliziyo kwaye zinokuphucula ukuchaneka kokuhamba kwegazi okuphantsi

Isikhokelo Sokuyisebenzisa Esisebenzayo

Kwizicelo eziSisiseko (Ulawulo lwesandla):

1. Sebenzisa umbane oguquguqukayo onohlengahlengiso lwevolthi
2. Faka i-potentiometer elandelelanayo ngepompo yakho ye-peristaltic ye-12v
3. Linganisa izinga lokuhamba kwamanzi kwiindawo ezahlukeneyo zolawulo

Kwizicelo ezibalulekileyo:

• 1. Sebenzisa iimpompo ze-peristaltic eziqhutywa yi-stepper motor
• 2, Sebenzisa ulawulo oluvaliweyo olunezinzwa zokuhamba kwamanzi
• 3, Yongeza iinkqubo zempendulo ukuze ufumane imbuyekezo

Ukulinganisa kunye nokuqinisekisa

Nokuba yeyiphi na indlela yokulawula, ukulinganisa kubalulekile:

1. 1, Qokelela imveliso kwixesha elilinganisiweyo
2. 2. Bala izinga lokuhamba kokwenyani: Umthamo/Ixesha
3. 3, Yenza i-calibration curve enxulumene nesignali yokulawula ukuya kwisantya sokuhamba
4. 4, Qinisekisa ukuchaneka kulo lonke uluhlu lokusebenza

Kwimpompo ye-peristaltic yamanzi, linganisa ulwelo olusetyenziswayo, njengoko umahluko we-viscosity uchaphazela iimpawu zokuhamba kwamanzi.

Ukusombulula iingxaki zezinga lokuhamba kwamanzi

• 1, Ukuhamba okungahambelaniyo: Jonga ukuba iityhubhu zigugile na, ukungazinzi kwenjini, okanye ukuguquguquka kwevolthi
• 2. Ukuncipha kokuhamba komoya okuphezulu: Hlola ukuba akukho monakalo kwiityhubhu, ukuguguleka kwemoto, okanye uxinzelelo oluphezulu lwenkqubo
• 3. Iziphumo zePulsation: Cinga ngokongeza ii-pulse dampers okanye ukwandisa inani leeroller

Amaqhinga oLawulo oluPhambili

• 1, Ukuhlanganiswa kwe-PLC: Kwizicelo zoshishino
