Yiziphi izinhlobo zezinzwa zezinga lamanzi?
Nazi izinhlobo ezingu-7 zezinzwa zeleveli ye-liquid zereferensi yakho:
1. Inzwa yezinga lamanzi optical
Inzwa yokubona iyisimo esiqinile. Basebenzisa ama-LED we-infrared nama-phototransistors, futhi uma inzwa isemoyeni, ahlanganiswe ngokubonakalayo. Uma ikhanda lenzwa licwiliswa oketshezini, ukukhanya kwe-infrared kuzophuma, kubangele okukhiphayo ukuthi kushintshe. Lezi zinzwa ziyakwazi ukubona ubukhona noma ukungabikho cishe kwanoma yiluphi uketshezi. Azizweli ekukhanyeni okuzungezile, azithintwa igwebu lapho zisemoyeni, futhi azithintwa amabhamuza amancane lapho zisemanzini. Lokhu kuzenza zibe usizo ezimweni lapho izinguquko zesimo kufanele zirekhodwe ngokushesha nangokuthembekile, nasezimeni lapho zingasebenza khona ngokwethembeka isikhathi eside ngaphandle kokunakekelwa.
Izinzuzo: ukulinganisa okungaxhunywanga, ukunemba okuphezulu, nokuphendula okusheshayo.
Ububi: Ungasebenzisi ngaphansi kwelanga eliqondile, umhwamuko wamanzi uzothinta ukunemba kokulinganisa.
2. I-Capacitance liquid level sensor
Ukushintsha kwezinga le-Capacitance kusebenzisa ama-electrode angu-2 (ngokuvamile enziwe ngensimbi) kumjikelezo, futhi ibanga phakathi kwawo lifushane kakhulu. Lapho i-electrode icwiliswa oketshezini, iqeda umjikelezo.
Izinzuzo: ingasetshenziswa ukunquma ukuphakama noma ukuwa koketshezi esitsheni. Ngokwenza i-electrode kanye nesitsha ukuphakama okufanayo, amandla phakathi kwama-electrode angalinganiswa. Akukho capacitance kusho akukho uketshezi. Umthamo ogcwele umele isitsha esiphelele. Amanani alinganiselwe okuthi “okungenalutho” kanye “nokugcwele” kufanele kurekhodwe, bese kusetshenziswa amamitha alinganisiwe angu-0% no-100% ukuze kuboniswe izinga loketshezi.
Ukungalungi: Ukugqwala kwe-electrode kuzoshintsha amandla e-electrode, futhi idinga ukuhlanzwa noma ukulinganisa kabusha.
3. Ukulungisa inzwa yezinga lemfoloko
I-tuning fork level gauge iyithuluzi lokushintsha izinga lephuzu eliwuketshezi elidizayinwe ngomgomo wokulungisa wefoloko. Umgomo wokusebenza weswishi uwukubangela ukudlidliza kwawo ngokusebenzisa i-resonance yekristalu ye-piezoelectric.
Yonke into ine-resonant frequency. Imvamisa ye-resonant yento ihlobene nosayizi, ubukhulu, ukwakheka, amandla… wento. Isibonelo esijwayelekile semvamisa yokukhala kwento ukuthi: inkomishi yengilazi efanayo elandelanayo Ukugcwalisa ngamanzi anobude obuhlukene, ungenza ukusebenza komculo wezinsimbi ngokuthepha.
Izinzuzo: Ingaphazanyiswa ngempela ukugeleza, amabhamuza, izinhlobo zoketshezi, njll., futhi akukho ukulinganisa okudingekayo.
Ukubi: Ayikwazi ukusetshenziswa kumidiya ye-viscous.
4. Inzwa yezinga le-diaphragm liquid
Iswishi yeleveli ye-diaphragm noma ye-pneumatic incike kumfutho womoya ukuze usunduze i-diaphragm, esebenza neswishi encane ngaphakathi komzimba oyinhloko wedivayisi. Njengoba izinga loketshezi likhula, ingcindezi yangaphakathi kushubhu yokuthola izokhuphuka kuze kube yilapho kwenziwa kusebenze i-microswitch. Njengoba izinga le-liquid lehla, umfutho womoya nawo wehla, futhi inkinobho iyavuleka.
Izinzuzo: Asikho isidingo samandla ethangini, ingasetshenziswa nezinhlobo eziningi zoketshezi, futhi iswishi ngeke ihlangane noketshezi.
Ukubi: Njengoba kuwumshini, uzodinga ukulungiswa ngokuhamba kwesikhathi.
5.Inzwa yezinga lamanzi entantayo
Iswishi ye-float iyinzwa yeleveli yoqobo. Ziyimishini eyimishini. I-float engenalutho ixhunywe engalweni. Njengoba iflothi iphakama futhi iwe oketshezini, ingalo izophushwa iye phezulu naphansi. Ingalo ingaxhunywa kuswishi kazibuthe noma yemishini ukuze kunqunywe ukuvuleka/ukucisha, noma ingaxhunywa kugeji yeleveli eshintshayo isuke ekubeni igcwele iye engenalutho lapho izinga loketshezi lehla.
Ukusetshenziswa kwamaswishi okuntanta kumaphampu kuyindlela eyongayo nephumelelayo yokukala izinga lamanzi emgodini wokumpompa wegumbi elingaphansi.
Izinzuzo: Iswishi ye-float ingakala noma yiluphi uhlobo loketshezi futhi ingaklanywa ukuthi isebenze ngaphandle kokunikezwa kwamandla.
Ukubi: Makhulu kunezinye izinhlobo zokushintshwa, futhi ngenxa yokuthi angomshini, kufanele asetshenziswe kaningi kunamanye amaswishi ezinga.
6. Ultrasonic liquid level inzwa
I-ultrasonic level gauge iyi-gauge yezinga ledijithali elawulwa yi-microprocessor. Esilinganisweni, i-pulse ye-ultrasonic ikhishwa inzwa (transducer). Igagasi lomsindo liboniswa indawo ewuketshezi futhi yamukelwe inzwa efanayo. Iguqulwa ibe isignali kagesi ngekristalu ye-piezoelectric. Isikhathi esiphakathi kokudluliswa nokwamukela igagasi lomsindo sisetshenziselwa ukubala Isilinganiso sebanga ukuya phezulu koketshezi.
Isimiso sokusebenza senzwa yezinga lamanzi ye-ultrasonic ukuthi i-ultrasonic transducer (probe) ithumela igagasi lomsindo we-high-frequency pulse lapho ihlangana nobuso bezinga elilinganisiwe (impahla), iyaboniswa, futhi i-echo ebonisiwe itholwa i-transducer futhi iguqulwe ibe isignali kagesi. Isikhathi sokusabalalisa segagasi lomsindo. Ilingana nebanga ukusuka kugagasi lomsindo ukuya phezulu kwento. Ubudlelwano phakathi kwebanga lokudluliswa kwegagasi lomsindo S kanye nesivinini somsindo C kanye nesikhathi sokudlulisa umsindo esingu-T bungavezwa ngefomula: S=C×T/2.
Izinzuzo: ukulinganisa okungathinteki, okuphakathi okukaliwe cishe akunamkhawulo, futhi kungasetshenziswa kabanzi ukukala ukuphakama koketshezi oluhlukahlukene nezinto eziqinile.
Ukungalungi: Ukunemba kokulinganisa kuthintwa kakhulu izinga lokushisa nothuli lwendawo yamanje.
7. I-radar level gauge
Ileveli yoketshezi lwe-radar iyithuluzi lokulinganisa izinga loketshezi elisuselwe kumgomo wokuhamba kwesikhathi. Igagasi le-radar ligijima ngesivinini sokukhanya, futhi isikhathi sokusebenza singaguqulwa sibe isignali yezinga yizingxenye ze-elekthronikhi. I-probe ithumela ama-high-frequency pulses ahamba ngesivinini sokukhanya emkhathini, futhi lapho ama-pulses ehlangana nobuso bezinto ezibonakalayo, ayaboniswa futhi amukelwe umamukeli kumitha, futhi isignali yebanga iguqulwa ibe yizinga. isignali.
Izinzuzo: ububanzi bohlelo lokusebenza, aluthinteki izinga lokushisa, uthuli, umusi, njll.
Ukungalungi: Kulula ukukhiqiza i-echo yokuphazamiseka, ethinta ukunemba kokulinganisa.
