1. Isingeniso Somkhiqizo
Imitha yezinga le-ultrasonic yochungechunge lwe-LMUiyidivayisi yokulinganisa ehlanganisiwe enezintambo ezimbili eqalwe yiLanry Instruments. Iqukethe inzwa ye-probe ehlanganisiwe kanye neyunithi yokucubungula kagesi enesakhiwo esivalwe ngokuphelele esingavumeli ukuvuza, okuvumela ukuqapha okuqhubekayo kwezinga lokungathintani koketshezi nezinto eziqinile. Ifanelekela izimo zokusebenza ezinzima embonini yensimbi, amakhemikhali, amandla kagesi, uphethiloli kanye neminye imboni, umkhiqizo usekela ukufakwa kwezikulufo kanye ne-flange. Ngokwamukela isimiso sokulinganisa isikhathi sokundiza esivuthiwe, esihlonyiswe ngesinxephezelo sokushisa okuzenzakalelayo kanye nobuchwepheshe bokucubungula isignali obuhlakaniphile, ikhipha ngokuzinzile izimpawu ze-analog ezijwayelekile ze-4-20mA, esebenza njengesixazululo esijwayelekile sokuqapha izinga lethangi kanye ne-silo.
Uchungechunge lwe-LMUIhlanganisa amamodeli ayisikhombisa ahlukaniswe ngebanga lokulinganisa eliphezulu: i-LMU4, i-LMU6, i-LMU8, i-LMU12, i-LMU15, i-LMU20 kanye ne-LMU30, kanye nebanga lokulinganisa uketshezi elihlanganisa u-4m kuya ku-30m. Kwezinto eziqinile, amagagasi e-ultrasonic ahlakazeka kalula futhi amuncwa yimpuphu, ngakho-ke ibanga lokulinganisa elisebenzayo lingu-50% kuphela walokho ezimweni zokusebenza koketshezi. Ukukhethwa kwemodeli kufanele kufane nendawo yokufaka endaweni kanye nezici zezinto. Iyunithi yonke ifinyelela izinga lokuvikelwa kwe-IP67; isembozo sayo sangaphandle sensimbi sinokungena komoya kanye nokumelana ne-alkali, okuvumela ukusebenza okuzinzile kwesikhathi eside ngaphansi kwengcindezi evamile ye--40℃ ~ 80℃ kanye ne-±0.1MPa.
2. Isimiso Sokulinganisa Okuyinhloko
Idivayisi iqedela ukukala ibanga nge-indlela ye-acoustic yesikhathi sokundiza: inzwa ikhipha ama-pulse e-ultrasonic phansi. Ngemva kokushaya ubuso bezinto ezibonakalayo, amaza omsindo abuyela emuva ku-probe. Imitha iqopha isikhathi sokuphumula u-t phakathi kokudluliselwa kanye nokwamukelwa, bese ibala ibanga u-D ukusuka ku-probe kuya ebusweni bezinto ezibonakalayo kuhlanganiswe nesivinini somsindo u-c, ilandela ifomula: D=c·t/2.
Abasebenzi bafaka ukuphakama okuphelele kokufakwa kwethangi u-H (ibanga lethangi elingenalutho) kusengaphambili, bese imitha iguqula ngokuzenzakalelayo izinga lesikhathi sangempela u-L=HD. Inzwa yokushisa ehlanganisiwe eyakhelwe ngaphakathi ibuyekeza ukuphambuka kwejubane lomsindo okubangelwa izinguquko zokushisa ngesikhathi sangempela ukuze kuqedwe amaphutha okulinganisa avela ekushiseni okuzungezile.
Ithuluzi linebanga elingenalutho (indawo efile B), lapho ama-echo angenakutholakala khona. Isethi ephelele yesilinganiso F ngesikhathi sokulinganisa akumele idlulele ebangeni elingenalutho. Ibanga elingenalutho lemodeli ngayinye liyanda kusuka ku-0.2m kuya ku-1.2m, futhi amamodeli ebanga elide adinga isikhala esikhulu sokufakwa esigciniwe. Amasethi amabili kuphela amapharamitha (ukuphakama kwethangi elingenalutho kanye nesilinganiso esigcwele) okudingeka afakwe ukuze kulinganiswe ngokushesha. Izinkinobho ezintathu zokungenisa kanye nesibonisi esikhulu se-LCD esinezinombolo ezine zisekela ukulungisa nokufunda okulula endaweni.
3. Izici Zomkhiqizo Eziyinhloko
- Umklamo ohlanganisiwe ohlangene: Inzwa kanye neyunithi kagesi kuhlanganiswe njengento eyodwa, kunezinketho zokufaka izikulufo/i-flange ukuze kube lula ukuyiqaqa nokufaka ngaphandle kwezintambo ezihlukene.
- Ukuvikelwa kwe-Multi-circuit: Amamojula okuvikela i-overvoltage eyakhelwe ngaphakathi, i-overcurrent kanye nombani, avumelana nezimo eziyinkimbinkimbi zokunikezwa kwamandla ezimbonini.
- Umthamo omuhle kakhulu wokulwa nokuphazamiseka: I-algorithm yesignali yedijithali ehlakaniphile ihlunga imfucuza ekhiqizwa umusi, uthuli, izisekelo zamatangi kanye nezinto ezivuselelayo, okufaka izimo zokusebenza zamatangi eziyinkimbinkimbi.
- Ukukhishwa kwesignali okujwayelekile: Ukukhishwa kwamanje okungu-4-20mA okunomthamo womthwalo ongu-0~500Ω, okuxhumeka ngqo ku-PLC, amarekhoda kanye neminye imishini yokulawula yezimboni; i-4mA ihambelana nethangi elingenalutho kanti i-20mA ihambelana nethangi eligcwele.
- Ukuzivumelanisa nezimo zokusebenza okubanzi: Indlu yensimbi kagesi, i-ABS sensor probe, i-IP67 engangeni uthuli, ukusebenza okungangeni manzi kanye nokumelana ne-alkali, okusebenza ezindaweni eziphansi/eziphezulu kanye nezinomfutho omncane.
- I-engeli yogongolo oluguquguqukayo: I-engeli yogongolo engu-8° (3dB) yamamodeli afushane angu-4/6/8m; I-engeli yogongolo engu-5° (3dB) yamamodeli akude angu-12~30m, okunciphisa ukuphazamiseka kwe-echo okuvela ezindongeni zethangi nokukhulisa ukuzinza kokulinganisa ibanga elide.
4. Izimo Zokusebenza
Ngenxa yezinzuzo zokungathintani, ukusebenza okungagugi kanye nokuhambisana nezinto eziqinile kanye noketshezi, uchungechunge lwe-LMU lusetshenziswa kabanzi ekuqapheni izindawo ezahlukene zokugcina izimpahla zezimboni:
- Imboni yamakhemikhali: Ukuqapha izinga lamathangi okugcina i-acid-base, amathangi alawula indle kanye namathangi e-reagent;
- Imboni kagesi: Amathangi amanzi ajikelezayo, ama-silos omlotha ompukane kanye namathangi odaka olususa i-sulfurization;
- Imboni yezinsimbi: Amachibi amanzi okupholisa, ama-silo amaminerali kanye namathangi e-slag slurry;
- Imboni kaphethiloli: Amathangi okugcina uwoyela ongahluziwe kanye namachibi okulahla indle okuhlukanisa uwoyela;
- Indawo yokugcina izinto evamile: Ukulinganiswa kwezinga eliqinile lama-silo okusanhlamvu, amabhokisi ezinhlayiya zepulasitiki kanye namayadi esihlabathi.
5.Isifinyezo
Uchungechunge lwe-LMUIsithumeli sezinga le-ultrasonic esihlanganisiwe siyidivayisi encane enama-wire amabili yokulinganisa uketshezi olungenakuthintana kanye nezinga eliqinile embonini yamakhemikhali, amandla, i-metallurgical kanye ne-petroleum. Njengoba isebenzisa isimiso sesikhathi sokundiza kanye nesinxephezelo sokushisa, ifaka ukuvikelwa kwe-IP67, umbani kanye nokuvikelwa kwe-overvoltage, ukuphuma okungu-4-20mA kanye nokunemba okungu-0.2%FS. Ama-engeli ahlukene ogongolo afanelana nezigaba ezahlukene zokulinganisa. Ayinawo ukugqwala kanye nokunamathela kwezinto, inikeza ukuqapha okuphansi kokunakekelwa kwamathangi, amachibi kanye nama-silo ngaphansi kwezimo zokusebenza ezinzima.
