1. Chiyambi cha luso la makina ozungulira oluka

1. Chidule chachidule cha makina oluka ozungulira

Makina oluka oluka mozungulira (monga momwe asonyezedwera pa Chithunzi 1) ndi chipangizo chomwe chimalukira ulusi wa thonje munsalu ya tubular.Amagwiritsidwa ntchito makamaka kuluka mitundu yosiyanasiyana ya nsalu zolukidwa, nsalu za T-sheti, nsalu zosiyanasiyana zokhala ndi mabowo, etc. Malinga ndi kapangidwe kake, zitha kugawidwa kukhala makina oluka a jersey ozungulira komanso makina oluka a jersey ozungulira, omwe ndi amagwiritsidwa ntchito kwambiri m'makampani opanga nsalu.

2. Zofunikira za ndondomeko

(1) Inverter imayenera kukhala ndi kukana kwamphamvu kwa chilengedwe, chifukwa kutentha kwa malo ogwirira ntchito pamalowa kumakhala kokwera kwambiri, ndipo ubweya wa thonje ukhoza kuchititsa kuti chozizira chozizira chiwonongeke ndikuwonongeka, ndipo mabowo ozizira atsekedwe.

(2) Flexible inching ntchito ntchito ikufunika.Mabatani a inching amayikidwa m'malo ambiri a zida, ndipo inverter imayenera kuyankha mwachangu.

(3) Pali maulendo atatu ofunikira pakuwongolera liwiro.Imodzi ndi inchiing ntchito liwiro, kawirikawiri mozungulira 6Hz;chinacho ndi liwiro lanthawi zonse loluka, lomwe limathamanga kwambiri mpaka 70Hz;chachitatu ndi ntchito yosonkhanitsa yotsika, yomwe imafunika pafupipafupi pafupifupi 20Hz.

(4) Pogwiritsa ntchito makina ozungulira ozungulira, kutembenuka kwa injini ndi kuzungulira ndizoletsedwa, mwinamwake singano za bedi la singano zidzapindika kapena kusweka.Ngati makina ozungulira ozungulira amagwiritsa ntchito gawo limodzi, izi sizingaganizidwe.Ngati dongosolo likuzungulira kutsogolo ndi kubwereranso Izo kwathunthu zimadalira kutsogolo ndi m'mbuyo kasinthasintha wa galimoto.Kumbali imodzi, ikuyenera kuletsa kusinthasintha kwapang'onopang'ono, ndipo kumbali ina, ikufunika kukhazikitsa DC braking kuti ithetse kuzungulira.

3. Zofunikira zogwirira ntchito

Mukaluka, katunduyo ndi wolemetsa, ndipo inching / kuyambitsa ndondomeko iyenera kukhala yofulumira, yomwe imafuna kuti inverter ikhale ndi mafupipafupi otsika, torque yaikulu, ndi liwiro lachangu.Makina osinthira pafupipafupi amatengera mawonekedwe owongolera vekitala kuti apititse patsogolo kukhazikika kwa injini ndikutulutsa torque yotsika.

4. Kuwongolera mawaya

Gawo lowongolera la makina oluka oluka ozungulira amatengera microcontroller kapena PLC + mawonekedwe owongolera makina amunthu.Ma frequency converter amayendetsedwa ndi ma terminals kuti ayambe ndi kuyimitsa, ndipo ma frequency amaperekedwa ndi kuchuluka kwa analogi kapena kuyika ma frequency angapo.

Pali njira ziwiri zowongolera zowongolera ma liwiro ambiri.Chimodzi ndicho kugwiritsa ntchito analogi kuti muyike pafupipafupi.Kaya ndikuthamanga kapena ntchito yothamanga kwambiri komanso yotsika kwambiri, chizindikiro cha analogi ndi malangizo ogwiritsira ntchito amaperekedwa ndi dongosolo lolamulira;ina ndiyo kugwiritsa ntchito ma frequency converter.Kukonzekera kwafupipafupi kwa masitepe ambiri, kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kapa bwino ka za ngokwe kapanganinganinganingani kusungwa miakambombo5khumishonishini yokhudzana ndi chilankhulo cha Chingerezi.

2. Zofunikira pa malo ndi dongosolo lotumidwa

(1) Zofunikira pa tsamba

Makina ozungulira oluka makina ali ndi zofunikira zosavuta pakugwira ntchito kwa inverter.Nthawi zambiri, imalumikizidwa ndi ma terminals kuti muwongolere kuyamba ndi kuyimitsa, ma frequency a analogi amaperekedwa, kapena ma-multi-speed amagwiritsidwa ntchito kuyika ma frequency.Kuthamanga kwa inching kapena kutsika kwambiri kumafunika kuti ikhale yachangu, kotero inverter imayenera kuwongolera mota kuti ipange torque yayikulu yotsika pafupipafupi.Nthawi zambiri, pakugwiritsa ntchito makina oluka ozungulira, mawonekedwe a V/F osinthira pafupipafupi ndi okwanira.

(2) Debugging chiwembu Chiwembu ife kutengera ndi: C320 mndandanda sensorless panopa vekitala inverter Mphamvu: 3.7 ndi 5.5KW

3. Debugging magawo ndi malangizo

1. Chithunzi cha waya

2. Sinthani mawonekedwe a parameter

(1) F0.0=0 VF mode

(2) F0.1 = 6 njira yolowera ma frequency akunja chizindikiro chakunja

(3) F0.4=0001 Kuwongolera kotheratu kwakunja

(4) F0.6=0010 kapewedwe ka kasinthasintha ndi koyenera

(5) F0.10=5 kuthamangitsa nthawi 5S

(6) F0.11=0.8 kuchepetsa nthawi 0.8S

(7) F0.16=6 chonyamulira pafupipafupi 6K

(8) F1.1=4 Torque yowonjezera 4

(9) F3.0=6 Khazikitsani X1 kupititsa patsogolo jog

(10) F4.10 = 6 ikani ma frequency a jog kukhala 6HZ

(11) F4.21=3.5 Khazikitsani nthawi yothamanga kukhala 3.5S

(12) F4.22=1.5 imayika nthawi yothamanga kukhala 1.5S

Debugging Notes

(1) Choyamba, thamangani kuti mudziwe kumene injiniyo ikulowera.

(2) Ponena za zovuta za kugwedezeka ndi kuyankha pang'onopang'ono panthawi yothamanga, kuthamanga ndi kutsika kwa nthawi yothamanga kumayenera kusinthidwa malinga ndi zofunikira.

(3) Ma torque otsika amatha kuwongolera posintha mafunde onyamulira ndi mphamvu ya torque.

(4) Ubweya wa thonje umatchinga njira yolowera mpweya ndi ma fani, zomwe zimapangitsa kuti inverter isatenthedwe bwino.Izi zimachitika kawirikawiri.Pakadali pano, inverter wamba amalumpha alamu yotentha kenako amachotsa pamanja chingwe cha mpweya asanayambe kuzigwiritsa ntchito.
