Isistimu yokulawula i-oxygen ehlakaniphile yokulawula ukuvutha
Isistimu yokulawula i-oxygen ehlakaniphile yokulawula ukuvutha
Uhlelo lokulawula oluhlakaniphile:
Uhlelo lokulawula ugesi luqukethe ikhabhinethi yokulawula kagesi eyinhloko kanye nebhokisi lokuhlangana ku-valve block.Ikhabethe eliyinhloko lokulawula ugesi liqukethe uhlelo lokulawula lwe-PLC.Isikrini sokuthinta kanye nenkinobho yokushintsha yesistimu ihlinzeka ngakho konke ukulawula inqubo nokuqalisa imisebenzi yokumisa.
◆ izici zobuchwepheshe zokulawula okuzenzakalelayo kwemishini:
1. Izinto zokusebenza zinesakhiwo esihlangene, i-skid iyonke, indawo encane yaphansi, akukho sakhiwo sengqalasizinda, ukutshalwa kwezimali okuncane, inqubo elula, imikhiqizo ekhulile, nokuhlukaniswa kwe-adsorption kwenziwa ekamelweni lokushisa;izingxenye ezibalulekile ezifana ne-valve ye-pneumatic kanye ne-electromagnetic pilot valve yizisetshenziswa zangempela ezivela kwamanye amazwe, ezinciphisa ukuguga kwevalvu futhi andise impilo yesevisi yemishini.
2. Imishini emihle, umsindo ophansi, ukungangcoli, ukusebenza kokuzamazama komhlaba okuqinile, ukukhetha kokuqala kwemikhiqizo yokonga amandla nokuvikela imvelo embonini yokuhlukanisa umoya.
3. Isilawuli esihlelekayo se-PLC (SMART S7-200) senkampani yakwa-Siemens yaseJalimane siqedela ukulawula isikhathi, ukushintsha okuzenzakalelayo kwe-valve yenqubo ye-PSA, futhi siqaphela ukusebenza okuzenzakalelayo okungahleliwe okuphelele esizeni.
4. Inkinobho yokukhetha "ekude / yendawo" isethelwe ukuqala nokumisa okokusebenza endaweni noma ukude.
5. Isignali yezinsimbi isebenzisa i-4-20 mA.DC .
6. Iyunithi yamukela isistimu yokulawula ye-PLC ethuthukisiwe, engaxhumana nomsebenzisi ikhompyutha ephezulu ye-DCS, igcine isixhumi esibonakalayo sokuxhumana se-RS485, futhi isebenzisane nomsebenzisi ngokususa iphutha nokumisa.
7. Umsebenzi wokuthulula okuzenzakalelayo wesistimu: lapho inkomba yobumsulwa yehluleka ukuhlangabezana nezidingo zekhasimende (inani lobumsulwa lingasethwa).
8. Ukuqapha nge-inthanethi ubumsulwa nokugeleza;i-alamu ezwakalayo nebonwayo uma ingafaneleki;isikhathi eside (isikhathi singasethwa) i-alamu ye-oxygen engafanelekile ingabona umsebenzi wokuvala okuzenzakalelayo.
9. Uhlelo lokulawula lungakwazi ukubona ukulungiswa okuzenzakalelayo nokunye ukulawula okudingekayo ngaphakathi kobubanzi bomzimba, futhi kungabona ukuqala, ukumisa, ukuvikelwa kwe-interlock, ukulungiswa okuzenzakalelayo kwe-PID kanye neminye imisebenzi yayo yonke idivayisi yokuhlinzeka komoya-mpilo.
10. Ukuhlanzeka kwegesi yomkhiqizo kungasethwa ngokuvumelana nezidingo zabasebenzisi, futhi kungalungiswa ngokuzenzekelayo nge-valve yokugeleza komoya-mpilo ngokuvumelana nokusetshenziswa komoya-mpilo wedivayisi yokukhiqiza ukuze kugcinwe ubumsulwa begesi lomkhiqizo lungaguquki, ukuze kongiwe amandla. ukusetshenziswa kohlelo.
11. Impumuzo ye-Manual kanye ne-self pressure kanye ne-blowdown ingabonakala eqenjini lamapayipi.
12. Izici zokulawula okuzenzakalelayo: I-Siemens PLC ehlakaniphile, isilawuli esihlakaniphile samazwe ngamazwe esidumile, sikhethiwe isilawuli esihlelekayo se-S7-200 njengomongo, sihlanganiswe nomklamo wokubukeka oyingqayizivele wenkampani, ingashintsha imingcele yokusebenza kwesistimu esizeni, futhi ibonise ukusebenza. izimo zesistimu ngayinye (isimo sokusebenza esilingisiwe, isimo sokucubungula okuzenzakalelayo komoyampilo, inkomba ye-alamu, i-alamu yephutha elimsulwa, irekhodi ledatha, ithrendi yedatha, njll.) ngephaneli yokulingisa.Inqubo yokusebenza inembile futhi ilula;isilawuli kude nesimo sokuqapha , okuzenzakalelayo, ukusebenza okwenziwa ngesandla kanye nesignali yokuxhumana eyomile yokwaziswa kwephutha;ngesixhumi esibonakalayo sokuxhumana se-RS485 ukubona ukuqapha okukude kwe-DCS, ithuluzi lingalinganiswa ngqo emoyeni, kulula ukulisebenzisa futhi linakekele.
◆ Umsebenzi wokuphrinta wedatha yokusebenza kwemishini:
Khetha iphrinta yomkhiqizo wasekhaya enesixazululo samaphoyinti angu-8 / mm nemigqa engu-384.Ukufakwa okushumekiwe, kulula ukuphrinta nokuthatha iphepha.Idizayini evalwe ngokugcwele, kulula ukufaka isakhiwo sephepha, ukhiye wokukhiya oyingqayizivele wedivayisi yokulawula ubuchwepheshe belungelo lobunikazi, ingavimbela ngempumelelo ukungavuli kahle komnyango womgqomo wephepha, ivikele ngempumelelo iphrinta umsebenzi ophephile nothembekile.Ukubukeka kwemfashini nokuhle, usayizi omncane nesisindo esincane, ukuphrinta okushesha kakhulu, okubushelelezi nokucacile, okungahlanganiswa kalula ohlelweni lokulawula imishini.
Kunezindlela ezintathu zokuphrinta:
A.Kumodi yokuphrinta okwenziwa ngesandla, chofoza inkinobho yokuphrinta esikrinini sokusebenza ukuze uphrinte ukusebenza kwemishini;
B.Imodi yokuhlola okuzenzakalelayo, i-PLC njalo, phrinta ukusebenza kwemishini;
Imodi yokuphuma kwe-C.Fault, lapho okokusebenza kusebenza, uma kwenzeka kungasebenzi, phrinta ukusebenza kwempahla.
Umsebenzi wokuphrinta ohlakaniphile: thatha isilawuli esihlelekayo se-Siemens PLC SMART S7-200 njengomongo, funda idatha esemqoka yokusebenza kwemishini, kuhlanganiswe nomklamo wokubukeka oyingqayizivele wenkampani, phrinta idatha yokusebenza kwemishini ngokuya ngokusebenza kwangempela kwenkampani. okokusebenza, okuhlanganisa imininingwane yephutha, imingcele yokusebenza, isimo sokusebenza, ulwazi lomsebenzisi kanye nesikhathi esihambisanayo, njll. Kungenza abaphathi bakhululeke futhi basheshe ukuqonda ukusebenza kwangempela kwemishini.
