Ukulawulwa okunembile koketshezi (amagesi noma uketshezi) kungenye yezidingo eziyinhloko emikhakheni yokwenza izinto ngokuzenzakalela kwezimboni, amadivayisi ezokwelapha, amathuluzi okuhlaziya, ngisho namakhaya ahlakaniphile. Nakuba ama-valve endabuko e-solenoid noma ama-valve omoya esetshenziswa kabanzi, avame ukwehluleka ezimweni ezidinga ukulawulwa okuncane kokugeleza, ukuphindaphinda okuphezulu kakhulu, ukugcinwa kwesikhundla ngokuphelele, noma uhlelo lokuvula oluyinkimbinkimbi. Ngalesi sikhathi, ama-motor amancane, anezinzuzo zawo zokusebenza ezihlukile, aya ngokuya eba “ubuchopho obuhlakaniphile” kanye “nomphathi we-agile” wezinhlelo zokulawula ama-valve eziphezulu, eqhuba inguquko eqondile ekulawulweni koketshezi.
1, Inselele yokulawula ama-valve kanye nokulingana okuphelele kwama-motor amancane
Izindlela zokulawula ama-valve zendabuko, njengezivalo ze-solenoid zohlobo lokushintsha, izivalo ezilinganayo ezithembele kumasignali e-analog noma ezinhlelweni zempendulo eziyinkimbinkimbi, zivame ukubhekana nemikhawulo elandelayo:
Ukunemba okunganele:Kunzima ukufeza ukulungiswa okuqondile kwamazinga okugeleza amancane kanye nokubekwa kokuvulwa okuphindaphindayo kakhulu.
Impendulo kanye nokuzinza:Amasignali e-analog angase aphazamiseke, futhi impendulo enamandla ingase ingabi ngcono. Ukugcina indawo kudinga ukusetshenziswa kwamandla okuqhubekayo (i-solenoid valve) noma ingcindezi yomthombo womoya (i-pneumatic valve).
Ubunzima:Ukufinyelela ukulawulwa okuvaliwe okunembe kakhulu kudinga izinzwa ezengeziwe (ezifana nama-encoder esikhundla, amamitha okugeleza) kanye nama-algorithms okulawula ayinkimbinkimbi, okwandisa izindleko kanye nomthamo.
Ukusetshenziswa kwamandla kanye nokukhiqizwa kokushisa:I-valve ye-solenoid idinga ukunikezwa amandla njalo ukuze igcine indawo yayo, okuholela ekusetshenzisweni kwamandla kanye nokukhiqizwa kokushisa.
Ukuvela kwama-motor amancane asebenza nge-stepper kunikeza izixazululo ezincintisana kakhulu kulezi zinselele:
Ukuma okuqondile kwe-loop evulekile:Ngaphandle kwesidingo sezinzwa ezengeziwe zesikhundla, ukulawulwa okunembile kokuvulwa kwevalvu (ivalvu ejikelezayo) noma isikhundla se-spool (ivalvu esebenza ngqo) kungatholakala ngokubala kwe-pulse, ngesisombululo sokuhlukaniswa kwezinyathelo ezincane (njengesinyathelo esingu-1/256) ukuya ekhoneni lesinyathelo (njenge-1.8 °), kufezwe ukulawulwa kokugeleza okunembile kakhulu.
Ukugcinwa kwesikhundla ngokuphelele:Ama-motor e-hybrid noma e-unomphela e-magnet stepper anganikeza i-torque yokubamba esimweni sokuma (ngisho noma engenawo amandla), aqinise i-valve endaweni ekhethiwe, futhi ukugcinwa kwamandla okungasebenzi kahle kuyinzuzo yawo enkulu.
Ukulawula kwedijithali, ikhono eliqinile lokulwa nokuphazamiseka:ukwamukela izimpawu ze-pulse zedijithali, ikhono eliqinile lokulwa nokuphazamiseka, i-logic yokulawula ecacile nelula.
Impendulo yokuma okusheshayo kokuqala:Ingaqala ngokushesha ukuma nokubuyela emuva, ivumelane nezidingo zokulungiswa okusheshayo.
Ukunciphisa okuncane: Ngosayizi omncane, kungafakwa ngqo emzimbeni wevalvu noma ku-actuator encane, okusindisa isikhala.
Ukusetshenziswa kwamandla okuphansi:Isebenzisa kuphela inani elikhulu lamandla kagesi ngesikhathi sokunyakaza, futhi amandla kagesi angancishiswa kakhulu ngesikhathi sokubamba okungaguquki (kusetshenziswa abashayeli abafanele), ngisho nokubamba ugesi (kuncike ekubambeni i-torque), okuholela ekusetshenzisweni kwamandla okuphansi.
2,Isakhiwo esijwayelekile kanye nemodi yokusebenza ye-valve eqhutshwa yi-micro stepper motor
Ukusetshenziswa kwama-motor ama-micro stepper ekulawuleni ama-valve kuncike kakhulu ezindleleni ezimbili eziyinhloko:
I-valve ejikelezayo yokushayela ngqo:
Isakhiwo:Umgodi wokukhipha wemoto ye-micro stepper uxhunywe ngqo esiqwini se-valve se-ball valve, i-butterfly valve, noma i-plug valve ngokusebenzisa i-coupling.
Umsebenzi:Injini ithola ama-pulse avela kumlawuli, ijikeleza ngokunembile i-engeli ethile (njenge-0-90 °), ishayela umongo we-valve (ibhola, ipuleti le-butterfly) ukuze ijikeleze, ishintshe indawo enqamula isiteshi sokugeleza, futhi ifinyelele ukulawula okuqondile noma okushintshiwe kwesilinganiso sokugeleza. I-Micro step drive ingaguquka kalula futhi inciphise umphumela wesando samanzi.
Izinzuzo:Isakhiwo esilula nesiqondile, ukusebenza kahle kokudlulisa okuphezulu, ukunemba kuncike ekhoneni lesinyathelo semoto kanye nekhono lokuhlukanisa izinyathelo ezincane.
I-valve esebenza ngqo (eqondile) yedrayivu:
Isakhiwo:Ama-motor ama-micro stepper ngokuvamile aguqula ukunyakaza okujikelezayo kube ukunyakaza okuqondile kwe-valve core ngokusebenzisa i-precision screw nut noma i-cam mechanism. I-motor iyajikeleza ukuze icindezele i-nut noma i-cam, eqhuba i-valve core (i-needle valve, i-globe valve core) ukuthi ihambe nge-axial, ilawula ngokunembile ukuvulwa kwe-valve.
Umsebenzi:I-pulse ngayinye ihambisana nokufuduka okuncane okuqondile kwe-valve core (njengama-micrometer ambalwa kuya kwamashumi ama-micrometer), okufeza ukulawulwa kokugeleza okunembe kakhulu.
Izinzuzo:Ifanele izimo ezidinga ukulawulwa okuqondile okuphezulu kakhulu, njengokulinganisa okuncane, ama-valve okujova okuhlaziywa kwe-chromatographic, njll. Indlela yezikulufo ngokwayo inikeza izinga elithile lekhono lokuzikhiya.
Izingxenye ezibalulekile:
Injini ye-Micro stepper:Umthombo wamandla oyinhloko, ukukhetha kudinga ukucabangela i-torque edingekayo, isivinini, ukunemba (i-angle yesinyathelo), usayizi, kanye nezidingo zemvelo.

Umzimba we-valve:Khetha ama-valve ebhola, ama-valve ebhabhathane, ama-valve enaliti, ama-valve e-diaphragm, njll. ngokusekelwe ezicini zoketshezi (ukugqwala, ukujiya, izinga lokushisa, ingcindezi), ububanzi bokugeleza, izidingo zokuvala, njll., bese wenza umklamo ovumelana nezimo.
Umshayeli we-Micro stepper:ithola izimpawu zokushaya kwenhliziyo kanye neziqondiso ezivela kubalawuli (PLC, microcontroller, njll.), ihlinzeka ngesimo samandla samanje esidingekayo sokugoqa izinjini, ifinyelela ukwahlukaniswa kwezinyathelo ezincane, ukulawula kwamanje, imisebenzi yokuvikela (ukushisa ngokweqile, ukushisa ngokweqile), njll. Abashayeli abasebenza kahle bayisihluthulelo sokukhulula amandla ezinjini.
Isilawuli:Uhlelo oluphezulu lubala futhi lukhiphe ukulandelana kwe-pulse okudingekayo kanye nesignali yesiqondiso ngokusekelwe enanini lesethi yokugeleza noma i-logic yohlelo.

Isixhumi esibonakalayo sedijithali, okulula ukusihlanganisa:isignali yokuqondisa i-pulse ejwayelekile, kulula ukuyixhuma nama-PLC ahlukahlukene, amakhompyutha ezimboni, izinhlelo ezifakiwe, ukuqaphela i-logic yokulawula eyinkimbinkimbi kanye nokuxhumana.
Impendulo esheshayo nokulawula okuguquguqukayo:Ukuma kokuqala, ukusheshisa, ukwehlisa ijubane, kanye nokuphendula okuphambene kuyashesha, futhi kungahlelwa ukuze kufezwe noma yiliphi ijika lokuvula.
Incane futhi ithembekile, kulula ukuyinakekela:Isakhiwo silula kakhulu, asinazo izibhulashi ezigugile, isikhathi eside senkonzo, kanye nezinzuzo ezisobala ezindaweni ezihlanzekile noma ezingenazo izilungiso.
