Lefoo Flowmeter Izicelo Embonini & Empilweni Yansuku Zonke

Ukukala ukuhamba kwamanzi kusetshenziswa kakhulu ekukhiqizweni kwezimboni nezolimo, ekwakhiweni kwezokuvikela izwe, ocwaningweni lwesayensi, ekuhwebeni kwamanye amazwe, nasemikhakheni eyahlukene yempilo yabantu's. Ekukhiqizweni kwemboni kaphethroliyamu, kusukela ekukhishweni kukawoyela, ezokuthutha, ukuncibilikisa nokucubungula kuya ekuthengiseni ngezohwebo, ukukala ukuhamba kwamanzi kuhamba kuyo yonke inqubo. Ayikho indawo engahlukaniswa nokukala ukuhamba kwamanzi, kungenjalo ukukhiqiza okuvamile nokuhwebelana embonini kaphethroliyamu ngeke kuqinisekiswe. . Embonini yamakhemikhali, ukukala ukuhamba kwamanzi okungaqondile kungabangela ukungalingani esilinganisweni sokusabalalisa izingxenye zamakhemikhali, kungakwazi ukuqinisekisa ikhwalithi yomkhiqizo, futhi kuvele izingozi ezinzima zokuphepha ekukhiqizeni. Ekukhiqizweni kwemboni kagesi, ukukala nokulungiswa kokuhamba koketshezi, igesi, umusi nezinye izinto eziphathi kudlala indima ebalulekile. Ukunemba kokukala ukuhamba kwamanzi akugcini nje ngokuba nokubaluleka okukhulu kwezomnotho ekuqinisekiseni ukuthi izikhungo zikagesi zisebenza ngaphansi kwemiphumela efanele, kodwa futhi ngentuthuko yamayunithi okushisa okuphezulu, umfutho ophezulu namandla amakhulu, ukukala ukuhamba kwamanzi sekuyisixhumanisi esibalulekile ekuqinisekiseni ukusebenza okuphephile kwezikhungo zikagesi. Uma ukuhamba kwamanzi okuphuthumayo kwamabhoyela amakhulu kuphazamiseka noma kuncishiswa, kungabangela izingozi ezinzima zokoma kwebhoyela noma ukuqhuma kwamapayipi. Lokhu kudinga ukuthi umshini wokukala ukuhamba kwamanzi ungagcini nje ngokukala ngokunembile, kodwa futhi ukhiphe isignali yezexwayiso ngesikhathi. Ekukhiqizweni kwemboni yensimbi nensimbi, ukukala ukuhamba kwamanzi ajikelezayo nomoya-mpilo (noma umoya) enqubweni yokwenza insimbi kungenye yemiphumela ebalulekile yokuqinisekisa ikhwalithi yomkhiqizo. Embonini ekhanyayo, yokudla, yendwangu nezinye izimboni, ukukala ukuhamba kwamanzi nakho akuhlukaniseki.

Iziguquli ezisetshenziswa kakhulu yilezo ezinamakhilikithi nezifakwayo. I-flowmeter ye-ultrasonic enomsindo owodwa ilula ngokwakhiwa futhi ilula ukuyisebenzisa, kodwa lolu hlobo lwe-flowmeter alunakho ukujwayela izinguquko ekusabalaleni kokuhamba. Ukuthuthukiswa okusheshayo kobuchwepheshe be-microelectronic nobuchwepheshe bekhompuyuthi kukhuthaze kakhulu ukushintshwa kwezinsimbi, futhi ama-flowmeter amasha avela njengezithombo. Kuze kube manje, kuthiwa ama-flowmeter angamakhulu afakwe emakethe, futhi izinkinga ezinzima eziningi ekusetshenzisweni emkhakheni kulindeleke ukuthi zixazululwe. Umsebenzi wobuchwepheshe besimanje bokukala ukuhamba kwamanzi ezweni lethu usemuva kancane. Ubekwe ekugcineni okuphezulu komgudu wokukala wokuhamba 6 futhi maqondana nezimbobo 11 no-12 ukuze kuncishiswe ukuhamba koketshezi okuzokala olungenayo ezimbenbeni 11 no-12; ingxenye yokulawula yokukala 19 isetshenziselwa ukukala isikhathi sokuhamba samaza e-ultrasonic phakathi kweziguquli ze-ultrasonic 8 no-9;

Iziyalezo Zokufaka & Ukusetshenziswa Kwe-Lefoo Flowmeters

I-flowmeter kufanele igweme izinto ezinamandla kazibuthe kanye nemishini enezinkambu ezinamandla kagesi (njengama-motor amakhulu, ama-transformer amakhulu, njll.), ukuze kungavinjelwa inkambu kazibuthe ukuthi ithinte inkambu yokusebenza kanye nesiginali yokuhamba kwe-sensor. Intambo yesiginali yokuhamba nentambo yokuvusa phakathi kwe-sensor ne-scoop converter. Kodwa-ke, ekuhlaziyweni kwezingxenye ezilimele ekuphazamisekeni kombani, iningi lama-voltage aphezulu afakiwe nama-surge amanje abangelwa iphutha angeniswa emgqeni wokunikezwa kukagesi wegumbi lokulawula, futhi ezinye izindlela ezimbili zincane. Njengoba i-electromagnetic flowmeter inamathuba amaningi okukala izinto eziqinile ezilengayo noma ukungcola kunamanye ama-flowmeter, amathuba okungasebenzi okubangelwa ungqimba lokunamathela odongeni lwangaphakathi aphezulu ngenani. Uma ukuhamba kukagesi kwengqimba lokunamathela kufana noketshezi. Izinkinga ezivamile ngesikhathi sokuqalisa ukusebenza ngokuvamile zibangelwa ukufakwa okungafanele.
