1. Nhanganyaya ye circular knitting machine technology

1. Muchidimbu sumo ye circular knitting machine

Muchina wekuruka wedenderedzwa (sezvinoratidzwa paMufananidzo 1) mudziyo unoruka shinda yedonje mumucheka wetubula.Inonyanya kushandiswa kuruka machira akasiyana-siyana akasimudzwa akarukwa machira, T-shirt machira, akasiyana machira ane pateni ane maburi, etc. Zvinoenderana nechimiro, inogona kupatsanurwa kuita single jersey denderedzwa knitting muchina uye kaviri jersey denderedzwa knitting muchina, ayo ari. inoshandiswa zvakanyanya muindasitiri yemachira.

2. Process zvinodiwa

(1) Iyo inverter inodiwa kuve nekudzivirira kwakasimba kwezvakatipoteredza, nekuti tembiricha yenzvimbo yekushanda yenzvimbo yakakwira zvakanyanya, uye mvere dzekotoni dzinogona kuita kuti fan inotonhorera idzikame uye ikuvadzwe, uye maburi ekutonhora avharwe.

(2) Flexible inching kushanda basa inodiwa.Inching mabhatani akaiswa munzvimbo dzakawanda dzemidziyo, uye inverter inodiwa kupindura nekukurumidza.

(3) Pane nhanho nhatu dzinodiwa mukudzora kumhanya.Imwe ndeye inching operation kumhanya, kazhinji kutenderera 6Hz;imwe yacho inokurumidza kuruka, ine frequency yepamusoro inosvika 70Hz;chechitatu ibasa rekuunganidza rakaderera, iro rinoda frequency ye20Hz.

(4) Panguva yekushanda kwechina denderedzwa yerukwa, mota kutenderedzwa uye kutenderera zvinorambidzwa zvachose, kana zvisina kudaro tsono dzemubhedha wetsono dzichakotamiswa kana kuputswa.Kana iyo denderedzwa yekuruka muchina inoshandisa imwechete-chikamu kubereka, izvi hazvingatariswe.Kana iyo system ichitenderera mberi uye ichidzokera Izvo zvachose zvinoenderana nekutenderera mberi uye kutenderera kutenderera kwemota.Kune rimwe divi, inoda kukwanisa kurambidza kutenderera kutenderera, uye kune rimwe divi, inoda kuseta DC braking kubvisa kutenderera.

3. Zvido zvekuita

Pakuruka, mutoro unorema, uye iyo inching / yekutanga maitiro inoda kukurumidza, izvo zvinoda kuti inverter ive yakaderera frequency, yakakura torque, uye nekukurumidza kupindura.Iyo frequency converter inotora vector control modhi yekuvandudza iyo mota yekumhanyisa kudzikamisa kurongeka uye yakaderera-frequency torque kubuda.

4. Kudzora wiring

Iyo inodzora chikamu chedenderedzwa yekuruka knitting muchina inotora microcontroller kana PLC + yemunhu-muchina interface control.Iyo frequency converter inodzorwa nematerminals kutanga nekumira, uye frequency inopihwa neanalog uwandu kana akawanda-nhanho frequency kuseta.

Pane chaizvo maviri ekudzora zvirongwa zveakawanda-kumhanya kudzora.Imwe ndeye kushandisa analog kuseta frequency.Ingave iri kumhanya kana kumhanya-mhanya uye kuderera-kumhanya-mhanya, iyo analog chiratidzo uye mirairo yekushandisa inopihwa neiyo control system;imwe yacho ndeye kushandisa frequency converter.Iyo yakavakirwa-mu-multi-stage frequency setting, iyo control system inopa akawanda-stage frequency switching chiratidzo, iyo jog inopiwa neiyo inverter pachayo, uye yakakwira-kumhanya yekuruka frequency inopiwa neanalog uwandu kana dhijitari yekumisikidza inverter.

2. Pa-saiti zvinodiwa uye kuronga kutumwa

(1) Pa-saiti zvinodiwa

Iyo denderedzwa yekurukisa muchina indasitiri ine zviri nyore zvinodiwa zvekutonga basa reiyo inverter.Kazhinji, yakabatana nematerminals kudzora kutanga uye kumira, analog frequency inopihwa, kana kuwanda-kumhanya kunoshandiswa kuseta frequency.Inching kana yakaderera-kumhanya kushanda inodikanwa kuti ikurumidze, saka inverter inodiwa kudzora mota kuti igadzire yakakura yakaderera-frequency torque pane yakaderera frequency.Kazhinji, mukushandiswa kwemichina yedenderedzwa yekuruka, iyo V/F modhi ye frequency converter inokwana.

(2) Debugging scheme Chirongwa chatinotora ndeichi: C320 series sensorless current vector inverter Simba: 3.7 uye 5.5KW

3. Debugging parameters uye mirayiridzo

1. Wiring diagram

2. Debug parameter setting

(1) F0.0=0 VF maitiro

(2) F0.1 = 6 frequency kupinza chiteshi chekunze chemazuva ano chiratidzo

(3) F0.4 = 0001 Kutonga kwekupedzisira kwekunze

(4) F0.6 = 0010 reverse kutenderera kudzivirira kunoshanda

(5) F0.10=5 nguva yekuwedzera 5S

(6) F0.11=0.8 deceleration nguva 0.8S

(7) F0.16=6 mutakuri frequency 6K

(8) F1.1=4 Torque inosimudzira 4

(9) F3.0=6 Isa X1 kumberi jog

(10) F4.10 = 6 isa frequency yejog ku6HZ

(11) F4.21=3.5 Isa nguva yekumhanyisa jog kusvika pa3.5S

(12) F4.22 = 1.5 inoisa nguva yejog ku1.5S

Debugging Notes

(1) Chekutanga, jog kuti uone kwakananga mota.

(2) Nezve matambudziko ekudedera uye kunonoka kupindura panguva yekumhanya, iyo yekumhanyisa uye yekudzikisa nguva yekumhanya inoda kugadziridzwa zvinoenderana nezvinodiwa.

(3) Yakaderera-frequency torque inogona kuvandudzwa nekugadzirisa inotakura wave uye torque inowedzera.

(4) Cotton wool inovharira mhepo duct uye feni zviteshi, zvichikonzera kushomeka kwekupisa kweiyo inverter.Mamiriro ezvinhu aya anowanzoitika.Parizvino, general inverter inosvetukira alarm yekudziya yobva yabvisa nemaoko lint mumhepo duct isati yaenderera mberi nekuishandisa.
