Nheyo dzePLC Operating Condition Monitoring System ye Induction Inoyunguta Moto

Iyo PLC inoshanda mamiriro ekutarisa sisitimu yeiyo induction inonyungudika choto inosanganiswa negumi-inch kuratidza skrini, ine mabasa akadai seanodzoreka uye anochinjika, otomatiki kuratidza, uye otomatiki ndangariro.

1. Iyo PLC yekunze control console ye induction melting furnace yakagadzirwa neDC voltmeter, DC ammeter, intermediate frequency voltmeter, intermediate frequency meter, intermediate frequency power meter, tembiricha yekuratidzira chiridzwa, etc. Midziyo yese yemidziyo inogona kuratidzwa intuitively. Iyo Siemens 10-inch touch screen inogona nyore kuseta oveni kana kunyungudika, uye inogona kuratidza tembiricha yekunyunguduka uye simba remidziyo uye mamwe ma curve eparameter munguva chaiyo. Iyo console yakagadzirirwa nekudzora simba switch, yepakati frequency manual uye otomatiki switch, emergency stop bhatani, simba chiratidzo chemwenje, yepakati frequency chiratidzo mwenje uye kukanganisa chiratidzo chenyevero.

2. Iyo yepakati ma frequency emagetsi ekudzora bhodhi inogadzirwa nekushisa kuvharwa-loop control interface. Iyo tembiricha yekudzora chiridzwa inosarudzwa kubva kuJapan Island Electric SR3 ine PID yekugadziridza chiridzwa. Iyo kure-infrared optical fiber thermometer inosarudzwa kubva kuGermany Optris CT series copper special thermometer, yekuyera tembiricha -40 -900°C. Kutanga, isa tembiricha yekudziya uye yekumhanyisa kumhanya pane tembiricha yekudzora chiridzwa kana PLC yekubata sikirini. Mushure mekunge simba ravhurwa, iyo thermometer inoyera tembiricha yekudziya munguva chaiyo uye inodzosera iyo kumudziyo wekudzora tembiricha. Iyo tembiricha yekudzora tembiricha inoenzanisa tembiricha yakayerwa neyakagadzika tembiricha yekudziya uye inoburitsa simulation Chiratidzo chinotumirwa kune yepakati frequency main control board, uye main control board inogadzirisa otomatiki iyo trigger angle ye thyristor zvinoenderana nechiyero chechiratidzo, kuitira kuti simba rinobuda remagetsi rinogadziriswa pamwe chete nechiyero chechiratidzo cheanalog, kubudirira chinangwa chekushisa chakavharwa-loop control. Kana kumhanya kwekudya kwechubhu yemhangura kuchigadziriswa, iyo thermometer inoona shanduko yekushisa yehubhu yemhangura, uye inoburitsa chiratidzo chazvino chinoenderana nekuenzanisa pakati peiyo tembiricha yakaonekwa uye tembiricha yakatarwa.

Kune yepakati frequency control board, iyo inobuda simba yepakati frequency magetsi magetsi anozogadziriswa kune inodiwa simba zvinoenderana nekuita chinangwa chekushisa kuvharwa-loop control.

CT yakatevedzana Optris yakakosha thermometer yekuyera mhangura

3. Iyo yepakati frequency switch yekunze control console inogadzirwa nemabhunu uye otomatiki oparesheni knobs. Kana iyo otomatiki modhi yasarudzwa, michina inotora tembiricha yakavharwa-loop control system, uye simba rekushandisa rinogadzirisa otomatiki simba rekubuda zvichienderana neyakagadzika tembiricha yekunyungudika. Iyo yepakati ma frequency emagetsi ekudzora bhodhi akagadzirwa ane tembiricha yakavharwa-loop control interface. Iyo tembiricha yekudzora chiridzwa inosarudza Shimadden SR3 ine PID yekugadziridza chiridzwa, uye kure-infrared fiber optic thermometer inosarudza iyo yeGerman Optris CT yakatevedzana yakakosha thermometer, uye tembiricha iri 385-1600 ℃. Kutanga kuseta tembiricha yekunyungudika pane tembiricha yekudzora chiridzwa kana PLC yekubata sikirini. Mushure mekunge magetsi epakati pekutanga atanga, thermometer inoyera tembiricha yecrucible munguva chaiyo uye inodzosera kumudziyo wekudzora tembiricha. Iyo tembiricha yekudzora tembiricha inofananidza tembiricha yakayerwa neyakagadzika tembiricha yekudziya uye yobva yaburitsa analogi chiratidzo kune IF main control board, iyo main control board inogadzirisa otomatiki iyo trigger angle ye thyristor zvinoenderana nechiyero chechiratidzo, kuti simba rekubuda. yemagetsi anogona kugadziriswa pamwe nechiyero chechiratidzo cheanalog. Kana mushandisi asarudza iyo yemanyorero ekushandisa modhi, mudziyo unonyungudika pane yakanyanya kubuda simba.

4. Mukuwedzera pakuratidza chimiro chekushanda kwechigadzirwa, chigadziro chekubata chinogonawo kutarisa kukanganisa kwemidziyo uye kupa mazano ekugadzirisa uye mamwe mashoko. Iyo yekushandisa inoperekedzwa nemidziyo yekushandisa maitiro, zvakajairika kutadza zviitiko uye nzira dzekurapa.

KANA magetsi ekupa PLC midziyo yekushandisa mamiriro ekutarisa system inogona kuve neanotevera mabasa:

1) Zadzisa kunyungudika kutonga manejimendi mabasa, otomatiki kukanganisa kuongororwa, otomatiki lining sintering uye mamwe mabasa. 2) 2) Yakakwana kunyunguduka maitiro ekudzora basa uye kutarisa kwakakwana, alarm uye kukanganisa kuzviongorora basa. 3) 3) Zadzisa ruzha uye chiedza alarm system, iyo inovhundutsa zvinotevera mamiriro:

Iyo frequency conversion cabinet inovhurwa;

Iyo capacitor yakakuvadzwa;

Kupisa kwemvura inotonhorera munharaunda imwe neimwe yemagetsi yakanyanyisa;

Simba rekutonhodza mvura yakaderera;

Tembiricha yemvura inotonhorera yechoto yakanyanya;

Kudzvinyirirwa kwemvura inotonhora yechoto kwakanyanya kuderera;

Kusarudzwa kwechoto / kuparadzanisa kushandura kwakashata;

Iyo inogadzirisa chikamu cheiyo inoshanduka frequency magetsi magetsi haina DC inobuda;

Kugadzika / kudonha kwevira rekuona alarm.

Kudzora kabati uye kugovera magetsi kuisirwa uye wiring tekinoroji:

Main switch: Incoming six-waya sere-waya system, kureva, matanhatu-phase magetsi, imwe-phase pasi waya, uye imwe-phase isina kwayakarerekera waya inogadziriswa ne wiring lugs. Iyo switch yekutsanangura huwandu ishoma pane mutoro weiyo sub-switch uye zvishandiso. Iyo main switch iri kure neDC24V magetsi. Dunhu guru rinoshandisa AC380V kana AC220V, uye dunhu rekutonga rinoshandisa DC24V.

Iyo yepasi mutsara bhari uye zero mutsara bhari yakamaka uye yakagadziriswa zvakateerana, uye muchinjika-pasi waya wakagadzirirwa pamusuwo wekutonga kabati.

Iyo yekudzora kutungamira yeimwe neimwe sub-switch yakanyorwa pane control cabinet gonhi.

Iyo kabati yekudzora inogadzirwa ine mudziyo wekufema (axial kuyerera fan uye air inlet grille fomu convection), uye mhepo yekutsinhana chiteshi inoshongedzerwa neguruva sefa.

Chishandiso chekuvhenekesa mucheti chekutonga chakamira kuti ive nechokwadi chekuti gonhi rakavhurwa, kana switch inoiswa kudzora mwenje.

Yese mitsara yenzira yekumisikidza inosanganisirwa mune trunking, uye iyo mutsara nhamba yakanyorwa zvakajeka. Nhamba yewaya haiperi uye inoenderana nedhirowa. Iyo dhayamita yewaya inosarudzwa zvakakodzera, uye iyo infrared thermometer inotarisa kuti hapana kupisa kana kuwandisa kwemitsara.

Isa mapuranga ekudzivirira ekudzivirira uye mabhodhi-asingapindi makonzo kune akafumura switch wiring nemabhawa emhangura.

Pamberi pekabati yekudzora, isa mapedhi erubha anoenderana nezvinodiwa zvekuchengetedza, senge insulation giredhi uye saizi.

Yemota yekudzora modhi: mhepo switch + contactor + thermal relay kana mota yekudzivirira switch + contactor yekudzora system.

Kugadzirisa nzira: Izvo zvikamu zvemagetsi zvakagadziriswa pane kabati yekudzora ine 35mm yakajairwa gwara renjanji.

Wiring nzira: Gadzirisa neterminal uye maka nhamba yewaya;

PLC chikamu: Iyo PLC yemagetsi magetsi ine inowirirana kuchengetedza zvivakwa; iyo PLC yakaiswa zvakasimba uye inofefeterwa zvakanaka; kupinza uye kubuda kunosiyaniswa nemitsara miviri; kune anopfuura mashanu I/O mapoinzi ekuchengetedza.

Inverter chikamu: huwandu hwacho hwakareba kupfuura iyo yakayerwa simba remota; mutsara unouya une hurongwa hwekudzivirira hunonzwisisika;

Shandisa multi-core flexible wire wiring trough mu cabinet; 220V uye DC24V waya mavara akaparadzaniswa; waya dzine nzvimbo isina munhu muchidyiro; kubuda kwemutsara wekugovera simba kunodzivirirwa nerubha; kuguma kwetambo kune nhamba yewaya yakajairika.

Wiring terminal chikamu: iyo terminal inoisirwa kumucheto kwepasi kwekutonga kabati, 380V uye DC24V yakaiswa zvakasiyana; iyo magetsi ekugovera kabhineti yakabatana kune peripheral midziyo ine aviation plugs kana wiring terminals.

Iyo yekunze trunking ndeye mwero, yakachengeteka, inoshingirira kutsika kudzvanywa, uye haina kukanganisa.

Mutsetse wekugadzira uri mutambo uye waya mugero mugero, uye inogovaniswa zvine mutsindo nemvura nemhepo nzira.

Iyo yekubatanidza mutsara nhamba mamaki eiyo yekupinza uye inobuda zvikamu zvemidziyo yakajeka, yakasimba, uye iri nyore kuwana pane saiti; havazorasikirwe nekuda kwekutsiviwa kwezvikamu;
