Kugwiritsa ntchito ma stepper motors poyesa kulemera

Makina opakira, gawo lofunika kwambiri ndikulemera zinthuzo. Zipangizo zimagawidwa m'magulu a ufa, zinthu zokhuthala, mitundu iwiri ya zinthu zolemera kapangidwe kake, njira yogwiritsira ntchito stepper motor ndi yosiyana, magulu otsatirawa a zipangizo akufotokozerantchito of mota ya steppermotsatana.

 

Kuyeza zinthu zophikidwa ndi ufa

 

Kuyeza kwa screw ndi njira yodziwika bwino yoyezera volumetric, kudzera mu kuchuluka kwa kuzungulira kwa screw kuti mupeze kuchuluka kwa muyeso, kuti mukwaniritse muyeso wa kukula kwa chosinthika ndikuwongolera kulondola kwa cholinga cha muyeso, zofunikira za liwiro la screw zitha kusinthidwa ndikuyikidwa molondola, kugwiritsa ntchitomota zoyendera masitepeakhoza kukwaniritsa zofunikira pa mbali zonse ziwiri.

Mwachitsanzo, makina oyezera ufa pogwiritsa ntchito mota ya stepper kuti azilamulira liwiro ndi kuzungulira kwa screw, sikuti zimangopangitsa kuti kapangidwe ka makina kakhale kosavuta, komanso zimapangitsa kuti zikhale zosavuta kuwongolera. Ngati palibe katundu, liwiro la mota ya stepper, malo oimikapo amangodalira kuchuluka kwa chizindikiro cha pulse ndi kuchuluka kwa ma pulse, ndipo sichikhudzidwa ndi kusintha kwa katundu, komwe kuli ndi ubwino wodziwikiratu wolondola poyerekeza ndi electromagnetic clutch control ya screw metering, yoyenera kwambiri kuyeza zipangizo zomwe zili ndi kusintha kwakukulu kwa mphamvu yokoka.

 

Mota ya stepper ndi screw pogwiritsa ntchito kulumikizana mwachindunji, kapangidwe kake ndi kosavuta komanso kosavuta. Ndikofunikira kunena kuti, popeza mphamvu yodzaza ya mota ya stepper imapangidwa kwambiri, ikadzaza pang'ono, padzakhala phokoso lalikulu. Chifukwa chake, pambuyo poti miyeso ya ntchito yapezeka, ndikofunikira kusankha kuchuluka kwa overload coefficient kuti zitsimikizire kuti mota ya stepper ikugwira ntchito bwino.

 

Kuyeza zinthu zokhuthala

 

Pompu yowongolera magiya ya stepper motor ingathandizenso kuwerengera molondola. Mapampu a magiya amagwiritsidwa ntchito kwambiri potumiza zinthu zokhuthala, monga madzi a manyuchi, phala la nyemba, vinyo woyera, mafuta, ketchup ndi zina zotero. Pakadali pano, powerengera zinthuzi, mapampu a pistoni amagwiritsidwa ntchito kwambiri, pali zovuta kuzisintha, kapangidwe kake kovuta, zovuta, kugwiritsa ntchito mphamvu zambiri, muyeso wolakwika ndi zofooka zina.

 

Kuyeza kwa pampu ya magiya kumayesedwa ndi magiya awiri omwe amalumikizana ndikuzungulira, zinthuzo zimakakamizika kuchokera ku cholowera kupita ku chotulukira kudzera m'malo a mano ndi mano. Mphamvu imachokera ku mota ya stepper, malo ndi liwiro la kuzungulira kwa mota ya stepper zimayendetsedwa ndi chowongolera chomwe chimakonzedwa, kulondola kwa mita kumakhala kokwera kuposa kulondola kwa mita ya pampu ya pistoni.

 

Galimoto ya stepper ndi yoyenera kugwiritsidwa ntchito pa liwiro lotsika, pamene liwiro likuchulukirachulukira, phokoso la galimoto ya stepper lidzawonjezeka kwambiri, ndipo zizindikiro zina zachuma zidzachepetsedwa kwambiri. Pa mapampu a giya othamanga kwambiri, kusankha kapangidwe ka liwiro kumakhala bwino. Mu makina opaka magiya okhuthala anayamba kugwiritsa ntchito kapangidwe ka galimoto ya stepper, phokoso limakhala lovuta kupewa, kudalirika kumachepa. Pambuyo pake, kugwiritsa ntchito njira ya spur gear speed kuti muchepetse liwiro la galimoto ya stepper, phokoso limayendetsedwa, kudalirika kwakulanso, kulondola kwa metering kumatsimikizika.
