1. Ukuqaliswa kweteknoloji yomatshini wokunitha ojikelezayo

1. Intshayelelo emfutshane yomatshini wokunitha ojikelezayo

Umatshini wokunitha ojikelezayo (njengoko kubonisiwe kuMfanekiso 1) sisixhobo esiluka umsonto wekotoni kwilaphu le-tubular.Isetyenziswa ikakhulu ukunitha iindidi ngeendidi zamalaphu ezinithiweyo anyusiweyo, amalaphu eT-shirt, amalaphu ahlukeneyo anepateni anemingxuma, njl.njl. Ngokwesakhiwo, inokohlulwa ibe yijezi enye umatshini wokunitha ojikelezayo kunye nomatshini wokunitha wejezi ophindwe kabini. isetyenziswa kakhulu kushishino lwamalaphu.

2. Iimfuno zenkqubo

(1) I-inverter iyadingeka ukuba ibe nokuchasana okunamandla kokusingqongileyo, kuba ubushushu bendawo yokusebenza kwindawo yokusebenza buphezulu kakhulu, kwaye uboya bomqhaphu ngokulula bunokubangela ukuba ifeni yokupholisa izinze kwaye yonakaliswe, kwaye imingxuma yokupholisa ivalwe.

(2) Umsebenzi we-inching eguquguqukayo uyafuneka.Amaqhosha e-inching afakwe kwiindawo ezininzi zezixhobo, kwaye i-inverter iyadingeka ukuba iphendule ngokukhawuleza.

(3) Kukho izantya ezithathu ezifunekayo kulawulo lwesantya.Enye isantya sokusebenza kwe-intshing, esiqhele ukujikeleza i-6Hz;enye isantya esiqhelekileyo sokuluka, esinesantya esiphezulu ukuya kuma-70Hz;eyesithathu yinkqubo yokuqokelela enesantya esisezantsi, efuna ukuphindaphinda malunga ne-20Hz.

(4) Ngexesha lokusebenza komatshini wokunitha ojikelezayo, ukuguqulwa kwemoto kunye nokujikeleza akuvumelekanga ngokupheleleyo, ngaphandle koko iinaliti zebhedi yenaliti ziya kugoba okanye zophuke.Ukuba umatshini wokunitha ojikelezayo usebenzisa i-single-phase bearing, oku akuyi kuqwalaselwa.Ukuba inkqubo ijikeleza phambili kwaye ibuyele umva Ixhomekeke ngokupheleleyo kwi-rotation yangaphambili kunye ne-reverse ye-motor.Kwelinye icala, kufuneka ikwazi ukunqanda ukujikeleza umva, kwaye kwelinye icala, idinga ukuseta i-DC braking ukuphelisa ukujikeleza.

3. Iimfuno zokusebenza

Xa uthunga, umthwalo unzima, kwaye inkqubo ye-intshi / ukuqalisa kufuneka ikhawuleze, efuna ukuba i-inverter ibe ne-frequency ephantsi, i-torque enkulu, kunye nesantya sokuphendula ngokukhawuleza.Isiguquli se-frequency samkela imowudi yokulawula i-vector ukuphucula ukuchaneka kozinzo lwe-motor kunye nokuphuma kwe-torque ephantsi.

4. Lawula iingcingo

Inxalenye yolawulo lwesetyhula yokunitha umatshini wokunitha ithatha i-microcontroller okanye i-PLC + ulawulo lojongano lomatshini wobuntu.I-converter frequency ilawulwa yi-terminals ukuqala kunye nokumisa, kwaye i-frequency inikwe ngobuninzi be-analog okanye i-multi-stage frequency setting.

Kukho izikimu zolawulo ezimbini zolawulo lwe-multi-speed control.Enye kukusebenzisa i-analog ukuseta i-frequency.Ingaba i-jogging okanye i-high-speed and low-speed operation, i-analog signal kunye nemiyalelo yokusebenza inikezelwa yinkqubo yokulawula;enye kukusebenzisa isiguquli samaza.Ukumiswa kwe-multi-stage frequency setting, inkqubo yokulawula inika umqondiso we-multi-stage frequency switching signal, i-jog inikezelwa yi-inverter ngokwayo, kwaye i-high-speed weaving frequency inikezwa ngobuninzi be-analog okanye i-digital setting ye-inverter.

2. Iimfuno ezikwisiza kunye nesicwangciso sokugunyazisa

(1) Iimfuno zesayithi

Umzi-mveliso womatshini wokunitha ojikelezayo uneemfuno ezilula kakhulu zomsebenzi wolawulo we-inverter.Ngokuqhelekileyo, idityaniswe kwii-terminals ukulawula ukuqala kunye nokuyeka, i-analog frequency inikwe, okanye i-multi-speed isetyenziselwa ukuseta i-frequency.I-inching okanye i-speed-speed operation kufuneka ikhawuleze, ngoko ke i-inverter iyafuneka ukulawula i-motor ukuvelisa i-torque enkulu ye-low-frequency frequency ephantsi.Ngokuqhelekileyo, ekusetyenzisweni koomatshini bokunitha abajikelezayo, imowudi ye-V / F ye-frequency converter yanele.

(2) Iskimu sokulungisa isikimu esisamkelayo yile: C320 series sensorless current vector inverter Power: 3.7 kunye 5.5KW

3. Iiparamitha zokulungisa iimpazamo kunye nemiyalelo

1. Umzobo wocingo

2. Debug parameter setting

(1) F0.0=0 indlela yeVF

(2) F0.1 = 6 ijelo lokufaka umjelo wangaphandle uphawu lwangoku

(3) F0.4=0001 Ulawulo lwetheminali yangaphandle

(4) F0.6=0010 uthintelo lokujikeleza umva luyasebenza

(5) F0.10=5 ixesha lokukhawuleza 5S

(6) F0.11=0.8 ixesha lokuthoba isantya 0.8S

(7) F0.16=6 umthwali rhoqo 6K

(8) F1.1=4 Unyuso lweTorque 4

(9) F3.0=6 Misela u-X1 ukuqhubela phambili ukubaleka

(10) F4.10 = 6 misela i-jog frequency ukuya kwi-6HZ

(11) F4.21=3.5 Seta ixesha lokubaleka ukubaleka libe yi-3.5S

(12) F4.22=1.5 ibeka ixesha lokubaleka ukuya kwi-1.5S

Debugging Notes

(1) Okokuqala, baleka ukuze ubone icala lemoto.

(2) Ngokubhekiselele kwiingxaki zokungcangcazela kunye nokuphendula okucothayo ngexesha lokugijima, ukukhawuleza kunye nokunciphisa ixesha lokugijima kufuneka lihlengahlengiswe ngokweemfuno.

(3) I-torque ye-low-frequency inokuphuculwa ngokulungelelanisa i-carrier wave kunye nokunyusa i-torque.

(4) Uboya belaphu buvalela umjelo womoya kunye nezitali zefeni, okubangela ukutshatyalaliswa okulambathayo kobushushu be-inverter.Le meko yenzeka rhoqo.Okwangoku, i-inverter jikelele itsiba i-alamu ye-thermal kwaye emva koko isuse ngesandla i-lint kwi-air duct ngaphambi kokuqhubeka ukuyisebenzisa.
