1. Chiyambi cha ukadaulo wa makina ozungulira oluka

1. Chiyambi chachifupi cha makina ozungulira oluka

Makina oluka ozungulira (monga momwe asonyezedwera pa Chithunzi 1) ndi chipangizo chomwe chimaluka ulusi wa thonje kukhala nsalu yozungulira. Amagwiritsidwa ntchito makamaka kuluka mitundu yosiyanasiyana ya nsalu zolukidwa zokwezedwa, nsalu za T-sheti, nsalu zosiyanasiyana zokhala ndi mabowo, ndi zina zotero. Malinga ndi kapangidwe kake, imatha kugawidwa m'magawo awiri: makina oluka ozungulira a jersey imodzi ndi makina oluka ozungulira a jersey awiri, omwe amagwiritsidwa ntchito kwambiri mumakampani opanga nsalu.

2. Zofunikira pa ndondomeko

(1) Chosinthira magetsi chikufunika kuti chikhale cholimba kwambiri pa chilengedwe, chifukwa kutentha kwa malo ogwirira ntchito ndi kwakukulu, ndipo ubweya wa thonje ungapangitse kuti fani yoziziritsira itayime ndikuwonongeka, komanso mabowo oziziritsira atsekeke.

(2) Ntchito yosinthasintha yogwirira ntchito yozungulira imafunika. Mabatani ozungulira amayikidwa m'malo ambiri pazida, ndipo inverter imafunika kuti iyankhule mwachangu.

(3) Pali ma speed atatu ofunikira pakulamulira liwiro. Limodzi ndi liwiro logwira ntchito la inching, nthawi zambiri pafupifupi 6Hz; lina ndi liwiro loluka, lomwe limakhala ndi ma frequency apamwamba kwambiri mpaka 70Hz; lachitatu ndi ntchito yosonkhanitsa yotsika, yomwe imafuna ma frequency pafupifupi 20Hz.

(4) Pa nthawi yogwira ntchito ya makina oluka ozungulira, kusintha ndi kuzungulira kwa injini n'koletsedwa kotheratu, apo ayi singano za bedi la singano zidzapindika kapena kusweka. Ngati makina oluka ozungulira amagwiritsa ntchito bearing ya gawo limodzi, izi sizingaganiziridwe. Ngati makinawo azungulira kutsogolo ndi kumbuyo Zimatengera kwathunthu kuzungulira kutsogolo ndi kumbuyo kwa injini. Kumbali imodzi, iyenera kuletsa kuzungulira kumbuyo, ndipo kumbali ina, iyenera kukhazikitsa DC braking kuti ichotse kuzungulira.

3. Zofunikira pakuchita bwino

Poluka, katundu amakhala wolemera, ndipo njira yoyambira/yoyambira iyenera kukhala yachangu, zomwe zimafuna kuti inverter ikhale ndi ma frequency ochepa, torque yayikulu, komanso liwiro loyankha mwachangu. Chosinthira ma frequency chimagwiritsa ntchito njira yowongolera vector kuti chiwongolere kulondola kwa liwiro la injini komanso kutulutsa ma torque ochepa.

4. Kulamulira mawaya

Gawo lolamulira la makina oluka ozungulira limagwiritsa ntchito microcontroller kapena PLC + mawonekedwe a munthu ndi makina. Chosinthira ma frequency chimayendetsedwa ndi ma terminals kuti ayambe ndi kuyimitsa, ndipo ma frequency amaperekedwa ndi kuchuluka kwa analog kapena kuyika ma frequency ambiri.

Pali njira ziwiri zowongolera zowongolera liwiro lambiri. Choyamba ndi kugwiritsa ntchito analog kukhazikitsa ma frequency. Kaya ndi kuthamanga kapena kuthamanga kwambiri komanso kuthamanga pang'ono, chizindikiro cha analog ndi malangizo ogwirira ntchito amaperekedwa ndi makina owongolera; china ndikugwiritsa ntchito chosinthira ma frequency. Makina owongolera omwe ali mkati mwake amakhala ndi ma frequency ambiri, makina owongolera amapereka chizindikiro chosinthira ma frequency ambiri, jog imaperekedwa ndi inverter yokha, ndipo ma frequency oluka mwachangu amaperekedwa ndi kuchuluka kwa analog kapena kuyika kwa digito kwa inverter.

2. Zofunikira pamalopo ndi dongosolo loyambitsa ntchito

(1) Zofunikira pamalopo

Makampani opanga makina oluka ozungulira ali ndi zofunikira zosavuta pa ntchito yowongolera ya inverter. Kawirikawiri, imalumikizidwa ku ma terminals kuti iyambe ndi kuyimitsa, ma frequency a analog amaperekedwa, kapena ma speed ambiri amagwiritsidwa ntchito kukhazikitsa ma frequency. Kugwira ntchito mwachangu kapena mwachangu kwambiri kumafunika kuti kukhale kofulumira, kotero inverter imafunika kuwongolera mota kuti ipange torque yayikulu yotsika kwambiri pama frequency otsika. Kawirikawiri, pakugwiritsa ntchito makina oluka ozungulira, njira ya V/F ya chosinthira ma frequency ndiyokwanira.

(2) Ndondomeko yokonza zolakwika Ndondomeko yomwe timagwiritsa ntchito ndi iyi: C320 series sensorless current vector inverter Mphamvu: 3.7 ndi 5.5KW

3. Kukonza zolakwika ndi malangizo

1. Chithunzi cha mawaya

2. Kusintha kwa magawo a cholakwika

(1) F0.0=0 VF mode

(2) F0.1=6 chizindikiro chakunja chakunja kwa njira yolowera pafupipafupi

(3) F0.4=0001 Kulamulira kwakunja kwa terminal

(4) F0.6=0010 kupewa kutembenuka mobwerera m'mbuyo ndikovomerezeka

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

(6) F0.11=0.8 nthawi yochepetsera liwiro 0.8S

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

(8) F1.1=4 Kukweza mphamvu ya torque 4

(9) F3.0=6 Ikani X1 kuti muyende patsogolo

(10) F4.10=6 khazikitsani ma frequency a jog ku 6HZ

(11) F4.21=3.5 Ikani nthawi yofulumira kuthamanga ku 3.5S

(12) F4.22=1.5 imayika nthawi yochepetsera liwiro la kuthamanga kukhala 1.5S

Zolemba Zokonza Ma Bug

(1) Choyamba, thamangani kuti mudziwe komwe injini ikupita.

(2) Ponena za mavuto a kugwedezeka ndi kuyankha pang'onopang'ono panthawi yothamanga, nthawi yothamanga mofulumira komanso yocheperako iyenera kusinthidwa malinga ndi zofunikira.

(3) Mphamvu yotsika kwambiri imatha kukonzedwa mwa kusintha mafunde onyamula ndi mphamvu yowonjezera mphamvu.

(4) Ubweya wa thonje umatseka njira yotulutsira mpweya ndi malo osungira mafani, zomwe zimapangitsa kuti inverter isatenthe bwino. Izi zimachitika kawirikawiri. Pakadali pano, inverter wamba imadumpha alamu yotenthetsera kenako n’kuchotsa pamanja chotchinga chomwe chili mu njira yotulutsira mpweya musanapitirize kuigwiritsa ntchito.
