Ungasarudza sei injini yemagetsi yeindasitiri?

Kune mhando ina dzemotokari dzinotakura otomatiki dzemaindasitiri:

1, Simba remabhiza rinogadziriswa uye simba remagetsi risingaperi: Simba remabhiza rinoshanduka uye simba remagetsi risingaperi rinosanganisira ma conveyors, macrane nemapombi egiya. Muzvishandiso izvi, simba remabhiza rinoramba riripo nekuti mutoro wacho unoramba uripo. Simba remabhiza rinodiwa rinogona kusiyana zvichienderana nekushandisa, izvo zvinoita kuti mota dzeAC neDC dzirambe dzichimhanya dzive sarudzo yakanaka.

2, Variable torque uye constant horsepower: Muenzaniso wevariable torque uye constant horsepower applications ipepa rekudzoreredza machine. Kumhanya kwezvinhu zvinoramba zvakafanana, zvinoreva kuti simba remabhiza harichinji. Zvisinei, sezvo dhayamita yeroll ichiwedzera, mutoro unochinja. Mumasystem madiki, iyi ishandisirwo yakanaka yemaDC motors kana maservo motors. Simba rekugadzirisa zvinhu zvakare inyaya uye rinofanira kufungwa nezvaro pakusarudza saizi yeinjini yeindasitiri kana kusarudza nzira yekudzora simba. MaAC motors ane encoders, closed-loop control, uye full-quadrant drives anogona kubatsira masisitimu makuru.

3, simba remagetsi rinogadziriswa uye torque: mafeni, mapombi e centrifugal uye ma agitators anoda simba remagetsi rinoshanduka uye torque. Sezvo kumhanya kwemota yeindasitiri kuchiwedzera, simba remagetsi rinobuda rinowedzerawo ne simba remagetsi rinodiwa uye torque. Mhando idzi dzemitoro ndipo panotangira hurukuro yekushanda zvakanaka kwemota, nema inverters anorodha ma AC motors achishandisa ma variable speed drives (VSDs).

4, kudzora nzvimbo kana kudzora torque: Mashandisirwo akadai semadhiraivha akatsetseka, anoda kufamba kwakanyatsojeka kunzvimbo dzakasiyana-siyana, anoda kumira kwakasimba kana kudzora torque, uye anowanzoda mhinduro kuti asimbise nzvimbo chaiyo yemota. Mamota eServo kana eStepper ndiwo akanakisa pamashandisirwo aya, asi mamota eDC ane mamota eAC ane mhinduro kana inverter ane encoders anowanzo shandiswa mumitsetse yekugadzira simbi kana mapepa uye mamwe mashandisirwo akafanana.

Mhando dzakasiyana dzemotokari dzeindasitiri

Kunyangwe paine mhando dzinopfuura makumi matatu nematanhatu dzemota dzeAC/DC dzinoshandiswa mumaindasitiri. Kunyangwe paine mhando dzakawanda dzemota, kune kupindirana kukuru mumaindasitiri, uye musika wave kusunda kuti kusarudzwa kwemota kuve nyore. Izvi zvinoderedza sarudzo inoshanda yemota mumashandisirwo mazhinji. Mhando nhanhatu dzemota dzakajairika, dzakakodzera mashandisirwo mazhinji, imota dzeDC dzisina mabhurashi uye dzakabvongodzwa, mota dzeAC squirrel cage newinding rotor, mota dzeservo nestepper. Mhando idzi dzemota dzakakodzera mashandisirwo mazhinji, nepo dzimwe mhando dzichishandiswa chete pamashandisirwo akakosha.

Mhando nhatu huru dzekushandiswa kwemotokari dzemaindasitiri

Mashandisirwo matatu makuru emota dzemaindasitiri ndeekumhanya kusingachinji, kumhanya kwakasiyana, uye kutonga kwenzvimbo (kana torque). Mamiriro akasiyana ezvishandiso zvemaindasitiri anoda mashandisirwo nematambudziko akasiyana pamwe nezvinetso zvavo. Semuenzaniso, kana kumhanya kwakanyanya kuri pasi pekumhanya kwemota, giya regiya rinodiwa. Izvi zvinobvumirawo mota diki kumhanya nekukurumidza kuri nani. Kunyange zvazvo paine ruzivo rwakawanda online rwekuti ungaziva sei saizi yemota, pane zvinhu zvakawanda izvo vashandisi vanofanira kufunga nezvazvo nekuti kune zvakawanda zvekufunga nezvazvo. Kuverenga inertia yemutoro, torque, uye kumhanya kunoda kuti mushandisi anzwisise maparameter akadai sehukuru hwese nehukuru (radius) hwemutoro, pamwe nekukweshana, kurasikirwa negiya regiya, uye kutenderera kwemuchina. Shanduko mumutoro, kumhanya kwekukurumidzira kana kudzikira, uye kutenderera kwebasa rekushandisa zvinofanirawo kufungwa nezvazvo, zvikasadaro mota dzemaindasitiri dzinogona kupisa zvakanyanya. Mota dzeAc induction isarudzo yakakurumbira yekushandiswa kwekufamba kwemota dzemaindasitiri. Mushure mekusarudza mhando yemota nehukuru, vashandisi vanofanirwawo kufunga nezvezvinhu zvakatipoteredza uye mhando dzedzimba dzemota, senge open frame uye stainless steel washing housing applications.

Maitiro ekusarudza mota dzeindasitiri

Matambudziko matatu makuru ekusarudzwa kwemota dzemaindasitiri

1. Mapurogiramu anomhanya nguva dzose?

Mukushandiswa kwemota inomhanya nekumhanya kwakafanana, mota iyi inowanzo mhanya nekumhanya kwakafanana isina kana kufunga nezvekumhanya nekudzikamisa mota. Rudzi urwu rwekushandisa runowanzo mhanya uchishandisa ma "on/off controls" akazara. Dunhu rekudzora rinowanzo kuve ne "branch circuit fuse" ine contactor, "overload industrial motor starter", uye "manual motor controller" kana "soft starter". Mamota ese ari maviri eAC neDC akakodzera kushandiswa kwekumhanya kwakazara. Mamota eDc anopa torque yakazara pakumhanya kwezero uye ane base hombe yekukwirisa. Mamota eAC akasarudzwawo zvakanaka nekuti ane simba rakawanda uye haadi kugadziriswa zvakanyanya. Kusiyana neizvi, hunhu hwepamusoro hwemota yeservo kana stepper hunogona kuonekwa sehwakanyanya kushandiswa kuri nyore.

2. App inoshanduka-shanduka yekukurumidza?

Mashandisirwo ekumhanya anochinja-chinja anowanzoda kusiyana kwekumhanya nekumhanya, pamwe chete nema ramps ekumhanyisa anotsanangurwa uye ekudzikamisa. Mukushandiswa kunoshanda, kuderedza kumhanya kwemainjini emaindasitiri, akadai semafeni nemapombi ecentrifugal, kunowanzoitwa kuti kuve nekushanda zvakanaka nekuenzanisa kushandiswa kwesimba nemutoro, pane kumhanya nekumhanya kwakazara uye kudzvanya kana kudzvinyirira kubuda. Izvi zvakakosha kufunga nezvazvo pakushandisa mashandisirwo akadai semitsetse yemabhodhoro. Kusanganiswa kwemainjini eAC neVFDS kunoshandiswa zvakanyanya kuwedzera kushanda zvakanaka uye kunoshanda zvakanaka mumhando dzakasiyana dzemashandisirwo ekumhanya anochinja-chinja. Mainjini eAC neDC ese ane madhiraivha akakodzera anoshanda zvakanaka mumhando dzakasiyana dzemashandisirwo ekumhanya anochinja-chinja. Mainjini eDc nemagadzirirwo emadhiraivha ave ari sarudzo chete yemainjini anochinja-chinja, uye zvikamu zvawo zvakagadzirwa uye zvakaratidzwa. Kunyangwe ikozvino, mainjini eDC anozivikanwa mumhando dzakasiyana dzekukurumidza, fractional horsepower applications uye anobatsira mumhando dzakasiyana dzekukurumidza nekuti anogona kupa torque yakazara pakumhanya kwakaderera uye torque inogara iripo pakumhanya kwakasiyana-siyana kwemainjini emaindasitiri. Zvisinei, kugadziriswa kwemainjini eDC inyaya yekufunga nezvayo, sezvo akawanda achida kushanduka nemabhurashi uye kupera nekuda kwekusangana nezvikamu zvinofamba. Mamota eDC asina brush anobvisa dambudziko iri, asi anodhura zvakanyanya pakutanga uye mhando dzemamota eindasitiri dziripo idiki. Kusashanda kwebhurashi hakusi dambudziko nemamota eAC induction, nepo madhiraivha anochinja-chinja (VFDS) achipa sarudzo inobatsira kumapurogiramu anodarika 1 HP, akadai semafeni uye kupomba, izvo zvinogona kuwedzera kushanda zvakanaka. Kusarudza rudzi rwedhiraivha kuti imhanye mota yeindasitiri kunogona kuwedzera ruzivo rwenzvimbo. Encoder inogona kuwedzerwa kumota kana application ichiida, uye drive inogona kutsanangurwa kuti ishandise mhinduro ye encoder. Nekuda kweizvozvo, iyi setup inogona kupa kumhanya kwakafanana neservo.

3. Unoda here kudzora chinzvimbo?

Kudzora nzvimbo kwakasimba kunowanikwa nekugara uchisimbisa nzvimbo yemota painofamba. Mashandisirwo akadai sekuisa madhiraivha emutsetse anogona kushandisa mamota estepper ane kana asina feedback kana mamota eservo ane feedback. Stepper inofamba chaiyo panzvimbo nekumhanya kuri pakati nepakati yobva yabata nzvimbo iyoyo. Open loop stepper system inopa simba rekutonga nzvimbo kana saizi yakakodzera. Kana pasina feedback, stepper ichafambisa nhamba chaiyo yematanho kunze kwekunge yasangana nekukanganiswa kwemutoro kupfuura kugona kwayo. Sezvo kumhanya uye simba rekushandisa zvichiwedzera, open-loop stepper control inogona kusasangana nezvinodiwa zvesystem, izvo zvinoda kukwidziridzwa kune stepper kana servo motor system ine feedback. Closed-loop system inopa chaiyo, high-speed motion profiles uye chaiyo position control. Servo systems dzinopa torque dzakakwirira kupfuura steppers pakumhanya kwakanyanya uye dzinoshanda zvirinani mu high dynamic loads kana complex motion applications. Kune high performance motion ine low position overshoot, reflective load inertia inofanira kuenderana ne servo motor inertia zvakanyanya sezvinobvira. Mune mamwe mashandisirwo, mismatch inosvika 10:1 yakakwana, asi 1:1 match ndiyo yakanaka. Kuderedza magiya inzira yakanaka yekugadzirisa dambudziko rekusawirirana kwemagiya, nekuti kusawirirana kwemutoro unoonekwa kunoderedzwa nechikamu chechiyero chekutumira, asi kusawirirana kwegiya kunofanirwa kutariswa mukuverenga.
