Ngophuculo lwemithetho eqhubekayo nechanekileyo yolawulo loqinisekiso lwemetroloji kwizinto ezikrwada, ngakumbi izinto eziqinileyo, uhlobo olutsha lwezixhobo zokuqinisekisa i-metrological.——Oomatshini bokuqinisekisa ubume bemetroloji belizwe abangenabunzima kunye nezixhobo baye babakho ngeminyaka yoo-1990. I-multihead weigher ngokuqhubekayo kwaye ngokuchanekileyo ilinganisa imathiriyeli ekrwada ngokotshintsho kubunzima bomnatha bezinto ezikrwada kumzimba wesikali. Ukuvela kwe-multihead weigher ngokucothayo kuthathe indawo yesikali sebhanti ye-elektroniki, isikali esijikelezayo kunye nesikali esipheleleyo.

Njengendlela yokulinganisa entsha kunye nephuculweyo, isetyenziswe ngokubanzi kwishishini lesinyithi, imigodi, isityalo sekhemikhali kunye neshishini lamandla ekhemikhali. Iqonga lenkonzo yokulinganisa, umgqomo wokutyisa kunye nabo bonke oomatshini kunye nezixhobo ezisebenza kwiqonga lenkonzo yokulinganisa zisetyenziswa njengomzimba wonke wobunzima, kwaye inzwa ngokuqhubekayo idlulisela utshintsho lobunzima bomnatha kumzimba wobunzima ukuya kwi-multihead weigher manipulator (i-manipulator iyasebenza. isitshixo se-multihead weigher Inxalenye yesisombululo, konke ukukhohlisa kunye nesisombululo kwenziwa ngayo). Isixhobo solawulo sibala i-net weight elastic coefficient yomzimba wesikali ngokweyunithi yeyunithi ngokwesiginali yedatha njengokuqukuqela okuthe ngqo okukhawulezileyo, kwaye emva koko uthelekise kunye neseti epheleleyo ekujoliswe kuyo.

Emva kokubala kwe-PID, isiphumo se-4-50mA yedatha yedatha yangoku, tshintsha i-frequency yemveliso ye-inverter yemoto yokutya, kwaye emva koko utshintshe umlinganiselo wesantya semoto, ukuze isixa esithile sokutya sisondele kangangoko kunokwenzeka kwithagethi epheleleyo ekujoliswe kuyo. njengoko ukuphumeza echanekileyo Indawo ekuyiwa kuyo ifidi. Ukuze ugqibezele ngcono ukondliwa okuqhubekekayo kunye nokuqinisekiswa kokuqinisekisa ukuchaneka kwe-multihead weigher, ihopha enkulu yokutyisa rhoqo kunye nevalve ezenzekelayo ezenzekelayo yokutyisa isondlo kufuneka ibekwe kumgqomo wokutyisa. Kukho ixabiso eliphezulu lomda (recharge_terinated) kunye nexabiso eliphantsi lomda (recharge_started) kwimitha yokulawula.

Xa ubunzima bomnatha kwisikali bufikelela kwixabiso elisezantsi lomda, isibonakaliso siya kuthunyelwa ukuvula ivalve yokulayishwa kwakhona, ivalve yokulayishwa kwakhona iya kuvulwa, izinto eziluhlaza kwindawo yokugcina impahla ziya kuthotywa kwibhini yokulayisha ngokuhambelana nonxibelelwano oluguquguqukayo. , kwaye ubunzima bomnatha kwisikali buya kwanda. Xa ubunzima bomnatha kwisikali bufikelela kwixabiso lokulayishwa kwakhona, apha kuyo yonke inkqubo, i-motor yokupasa isebenza ukusuka ekuqaleni ukuya ekupheleni, oku kuthetha ukuba ukudlula kuyaqhubeka.
