Mfundo za PLC Operating Condition Monitoring System for Induction Melting Furnace

Mfundo za PLC Operating Condition Monitoring System za Kuchotsa Kutentha Kwambiri

Dongosolo loyang’anira ntchito ya PLC ya ng’anjo yosungunuka yosungunuka imaphatikizidwa ndi chophimba cha 10-inch, chokhala ndi ntchito monga kuwongolera ndi kusinthika, kuwonetseratu, komanso kukumbukira.

1. PLC yoyendetsera kunja kwa ng’anjo ya ng’anjo yosungunula imakhala ndi DC voltmeter, DC ammeter, voltmeter yapakati pafupipafupi, mita yapakati pafupipafupi, mita yamagetsi yamagetsi, chida chowonetsera kutentha, etc. Zida zonse zogwiritsira ntchito zingathe kuwonetsedwa mwachidziwitso. The Siemens 10-inch touch screen akhoza kuyika ng’anjo kapena kusungunuka mosavuta, ndipo akhoza kusonyeza kutentha kwa kutentha ndi mphamvu ya zipangizo ndi ma curve ena a parameter mu nthawi yeniyeni. The console idapangidwa ndi switch switch power, intermediate frequency manual and automatic switch, batani loyimitsa mwadzidzidzi, kuwala kowonetsa mphamvu, kuwala kwapakati pafupipafupi komanso kuwala kochenjeza.

2. Bolodi loyendetsa magetsi lapakati lapakati limapangidwa ndi mawonekedwe a kutentha otsekedwa. Chida chowongolera kutentha chimasankhidwa kuchokera ku Japan Island Electric SR3 ndi chida chosinthira PID. Thermometer yakutali ya infrared optical fiber imasankhidwa kuchokera ku Germany’s Optris CT series copper special thermometer, yoyezera kutentha -40 -900°C. Choyamba, ikani kutentha kwa kutentha ndi kuthamanga kwa annealing pa chipangizo chowongolera kutentha kapena chophimba cha PLC. Mphamvu ikayatsidwa, thermometer imayesa kutentha kwanyengo mu nthawi yeniyeni ndikubwezeretsanso ku chida chowongolera kutentha. Chida chowongolera kutentha chimafananiza kutentha kwake ndi kutentha kwa kutentha ndikutulutsa kuyerekezera Chizindikirocho chimatumizidwa ku gulu lapakati pafupipafupi, ndipo gulu lalikulu loyang’anira limangosintha ma trigger angle ya thyristor molingana ndi kuchuluka kwa chizindikiro, kotero kuti mphamvu yotulutsa mphamvu yamagetsi imasinthidwa ndi mlingo wa chizindikiro cha analogi, kukwaniritsa cholinga cha kutentha kwatsekedwa-kuzungulira. Liwiro lodyetsa la chubu lamkuwa likasinthidwa, thermometer imazindikira kusintha kwa kutentha kwa chubu chamkuwa, ndipo imatulutsa chizindikiro chofananira chapano malinga ndi kuyerekezera kwa kutentha komwe kwapezeka ndi kutentha komwe kumayikidwa.

Kwa gulu lowongolera ma frequency apakati, mphamvu yotulutsa mphamvu yamagetsi yapakatikati idzasinthidwa kukhala mphamvu yofunikira kuti ikwaniritse cholinga cha kutentha kotsekedwa-loop control.

3. Kusintha kwapakati pafupipafupi kwa kontrakitala yowongolera kunja kumapangidwa ndi zida zamanja komanso zodziwikiratu. Njira yodziwikiratu ikasankhidwa, zidazo zimatengera kutentha kotsekeka-loop control system, ndipo zida zamagetsi zimasinthiratu mphamvu yotulutsa molingana ndi kutentha kosungunuka. Bolodi loyendetsa magetsi lapakati lapakati limapangidwa ndi mawonekedwe a kutentha otsekedwa. Chida chowongolera kutentha chimasankha Shimadden SR3 yokhala ndi chida chosinthira PID, ndipo choyezera chakutali cha fiber optic thermometer chimasankha thermometer yapadera ya German Optris CT, ndipo kutentha ndi 385-1600 ℃. Choyamba ikani kutentha kosungunuka pa chida chowongolera kutentha kapena chophimba cha PLC. Mphamvu yamagetsi ikayambika, thermometer imayesa kutentha kwanthawi yayitali ndikubwezeretsanso ku chipangizo chowongolera kutentha. Chida chowongolera kutentha chikufanizira kutentha kwake ndi kutentha kwa kutentha komwe kumayikidwa ndikutulutsa chizindikiro cha analogi ku gulu lalikulu la IF, gulu lalikulu lowongolera limangosintha ma trigger angle ya thyristor molingana ndi kuchuluka kwa chizindikiro, kuti mphamvu yotulutsa. mphamvu yamagetsi imatha kusinthidwa ndi mlingo wa chizindikiro cha analogi. Wogwiritsa ntchito akasankha njira yogwiritsira ntchito pamanja, chipangizocho chimasungunuka pamlingo waukulu kwambiri.

4. Kuwonjezera pa kusonyeza momwe ntchito yogwiritsira ntchito zipangizo, mawonekedwe ogwirira ntchito amathanso kuyang’anitsitsa kulephera kwa zipangizo ndikupereka malangizo okonzekera ndi zina. Ndondomeko yoyendetsera ntchito ikuphatikizidwa ndi njira zogwiritsira ntchito zida, zochitika zolephera zomwe zimachitika komanso njira zothandizira.

IF Power Supply PLC zida zowunikira magwiridwe antchito zitha kukhala ndi izi:

1) Malizitsani ntchito zowongolera zosungunula, kuzindikira zolakwika zokha, kuwongolera kwapang’onopang’ono ndi ntchito zina. 2) 2) Wangwiro kusungunula njira kulamulira ntchito ndi kuwunika mwangwiro, alamu ndi vuto kudzifufuza ntchito. 3) 3) Malizitsani ma alarm ndi kuwala kopepuka, komwe kungayambitse zotsatirazi:

Kabati yosinthira pafupipafupi imatsegulidwa;

Capacitor yawonongeka;

Kutentha kwa madzi ozizira mu dera lililonse la magetsi ndikokwera kwambiri;

Kuthamanga kwa madzi oziziritsa mphamvu ndikotsika kwambiri;

Kutentha kwa madzi ozizira a ng’anjo ndikokwera kwambiri;

Kuthamanga kwa madzi ozizira a ng’anjo ndikotsika kwambiri;

Kusintha kwa ng’anjo / kudzipatula ndikolakwika;

Gawo la rectifier lamagetsi osinthika pafupipafupi alibe DC;

Alamu yoyang’ana pansi / kutuluka kwa ng’anjo.

Control cabinet ndi kugawa magetsi kuyika ndi ukadaulo wama waya:

Kusintha kwakukulu: Dongosolo la mawaya asanu ndi limodzi omwe akubwera, ndiye kuti, magetsi a magawo asanu ndi limodzi, waya wagawo limodzi, ndi waya wagawo limodzi wokhazikika amakhazikika ndi zingwe zolumikizira. Mphamvu yosinthira masinthidwe ndi yocheperako kuposa katundu wa subswitch ndi zida. Kusintha kwakukulu kuli kutali ndi magetsi a DC24V. Dera lalikulu limagwiritsa ntchito AC380V kapena AC220V, ndipo dera lowongolera limagwiritsa ntchito DC24V.

Mzere wa mzere wapansi ndi zero mzere wa zero amalembedwa ndi kukhazikika motsatana, ndipo waya wodutsa pansi amapangidwira pakhomo la nduna yolamulira.

Mayendedwe owongolera a sub-switch iliyonse amalembedwa pachitseko chowongolera kabati.

Kabati yowongolera idapangidwa ndi chipangizo cholowera mpweya (axial flow fan ndi air inlet grille form convection), ndipo doko losinthira mpweya lili ndi fyuluta yafumbi.

Chida chowunikira mu kabati yowongolera chimakhala chokhazikika kuti chitseko chitsegulidwe, kapena chosinthira chimayikidwa kuti chiwongolere kuyatsa.

Mafotokozedwe onse a mizere amaphatikizidwa mu trunking, ndipo nambala ya mzere imalembedwa bwino. Nambala yawaya simazimiririka ndipo imagwirizana ndi kujambula. Kutalika kwa waya kumasankhidwa moyenerera, ndipo thermometer ya infrared imayang’ana kuti palibe kutenthedwa kapena kudzaza mizere.

Ikani matabwa otchinjiriza ndi matabwa oteteza makoswe pa mawaya owonekera ndi zitsulo zamkuwa.

Pamaso pa kabati yowongolera, ikani mapepala a mphira omwe amakwaniritsa zofunikira zachitetezo, monga kalasi ya insulation ndi kukula.

Pamayendedwe owongolera magalimoto: chosinthira mpweya + cholumikizira + cholumikizira chotenthetsera kapena chotchingira chitetezo chagalimoto + cholumikizira chowongolera.

Njira yokonzera: Zida zamagetsi zimakhazikika pa kabati yowongolera yokhala ndi njanji zowongolera za 35mm.

Njira yolumikizira: Konzani ndi terminal ndikuyika nambala yawaya;

Gawo la PLC: Mphamvu ya PLC ili ndi zida zodzitetezera; PLC imayikidwa molimba ndi mpweya wabwino; zolowetsa ndi zotuluka zimasiyanitsidwa ndi mizere iwiri; pali zoposa 5 I/O mfundo zosunga zobwezeretsera.

Inverter gawo: mphamvu ndi mlingo umodzi wapamwamba kuposa mphamvu oveteredwa galimoto; mzere wolowera uli ndi chitetezo chokwanira;

Gwiritsani ntchito mawaya amitundu yambiri osinthika mu nduna; Mitundu ya waya ya 220V ndi DC24V imasiyanitsidwa; mawaya ali ndi danga lopanda munthu mumpoto; kutulutsa kwa mzere wogawa mphamvu kumatetezedwa ndi mphira; kumapeto kwa waya kumakhala ndi nambala yokhazikika ya waya.

Wiring terminal gawo: terminal imayikidwa kumapeto kwa kabati yowongolera, 380V ndi DC24V imayikidwa padera; nduna yogawa mphamvu imalumikizidwa ndi zida zotumphukira ndi mapulagi oyendetsa ndege kapena ma wiring terminals.

Tsinde lakunja ndi lokhazikika, lotetezeka, losagonjetsedwa ndi kukakamizidwa, ndipo silimapunduka.

Mzere wopanga uli mu chingwe ndi waya mu ngalandeyo, ndipo umagawidwa bwino ndi madzi ndi mpweya.

Zizindikiro za mzere wolumikizira wa zolowetsa ndi zotulutsa za zida ndizomveka, zolimba, komanso zosavuta kuzipeza patsamba; sizidzatayika chifukwa cha kusintha kwa magawo;
