Mfundo ya akupanga lotseguka njira flowmeter ndi ntchito ya muyeso ubwino.

Mfundo yaikulu ya akupanga laser kuyambiraakupanga lotseguka njira flowmeterndi: molingana ndi kachipangizo kamene kamayikidwa pa weir (slot) kuyeza zida zoyezera, single-chip microcomputer mu open channel flow mita idapangidwa kuti itulutse siginecha inayake yamagetsi kuti ilimbikitse piezoelectric crystallization mu kafukufuku Tumizani chizindikiro cha data cha ultrasonic. ya mafupipafupi apadera, ndipo yambani chowerengera pa nthawi yotumiza ndikungoyamba kuwerengera nthawi. The akupanga deta chizindikiro ndi kufalikira malinga ndi kuyeza madzi mankhwala ndi kugunda muyezo mzati. Pakati pawo, gawo lina linayambitsa kuwonetsera koyamba, ndipo gawo lina linafalikiranso m'madzi. Gawo lachiwonetserocho limafalikira cham'mbuyo ndikulowa mu kafukufuku, zomwe zimapangitsa kuti chipangizochi chiziyenda mozungulira, zomwe zimapangitsa kutembenuka kwa mawu, mphamvu zamakina zamakina, ndi mphamvu yamagetsi yamagetsi kuti probe itulutse chizindikiro choyamba chamagetsi. Pamene akupanga yoweyula kufalikira kachiwiri m'madzi kufika pa madzi pamwamba, chifukwa pali nthunzi (gasi) pamwamba pa madzi pamwamba pa madzi, izo zimayambitsa yachiwiri kusinkhasinkha zikumveka mu nthunzi-zamadzimadzi mawonekedwe wosanjikiza, ndipo chimanyezimira echo ndi anamwazikana ndi kuonekera mmbuyo. kristalo wa piezoelectric. Chofufuzacho chimatulutsa chizindikiro china chamagetsi. Ndiko kuti, echo yowonekera koyamba imayambika pamalo ofotokozera (ndodo yokhazikika), ndipo yachiwiri yowoneka bwino imayambika pa mawonekedwe a nthunzi-zamadzimadzi. Pamene kafukufukuyo alandira mafunde owonetseredwa, nthawi yomweyo amathetsa nthawi. Panthawi imeneyi, nthawi imalembedwa. Chipangizocho chimalemba nthawi yofalitsa t ya akupanga yoweyula kuchokera kutumiza kupita ku kulandira. Ndipo T, molingana ndi chilinganizo H: ht/t0, (h ndi kutalika-m'lifupi chiŵerengero cha pamwamba pa weir (mphika)) ndi mbali chiŵerengero cha lotseguka njira flowmeter kafukufuku kwa madzi mlingo H.



Miyezo yolondola yosalumikizana: Sensa sikhudza zamadzimadzi, ndipo sichidzakokoloka ndikuipitsidwa ndi madzi oipa. Sensayo ndi chipolopolo chosindikizidwa cha ABS, chomwe chimagonjetsedwa ndi alkalis ndi dzimbiri, ndipo chimatha kugwiritsidwa ntchito kwa nthawi yaitali m'malo achilengedwe a chinyezi ndi ozizira; Yezerani nthawi yomweyo madzi amadzimadzi: Sensa nthawi yomweyo imayesa mita yamadzimadzi pamadzi amadzimadzi. Sichimagwiritsa ntchito zitsime zosasunthika, zomwe zingapewe kutsekereza chitoliro cholumikizira chifukwa chogwiritsa ntchito zitsime zosasunthika, zolimba zoyimitsidwa m'madzi otayira, mchenga wabwino, ndi zina zotere, zomwe zimapangitsa kuti zitsime zosasunthika komanso ma weirs oyezera kuzizira m'nyengo yozizira, mita ya alamu yonyenga imapangidwa, yomwe imayambitsa kuyeza kolakwika; Kusinthasintha kwapadziko lonse: Khazikitsani magawo akulu a zida zamagulu molingana ndi kiyibodi, yomwe ingagwiritsidwe ntchito pama weirs osiyanasiyana oyezera madzi. Miyezo yosiyanasiyana yogwiritsira ntchito monga kuphatikiza mu ngalande za ulimi wothirira nthaka ndi mapaipi a konkire apansi;



Thandizo lazambiri lautumiki: Chikalata chilichonse chikuwonetsa njira yoyika zida, njira yoyambira, kapangidwe ndi kukhazikitsa njira yoyezera madzi, komanso njira yoyezera ndi kutsimikizira kwapatuka kwathunthu; Ubwino wodalirika: Pambuyo pazaka zopanga, kugwira ntchito, komanso kumveka bwino kwaultrasonic lotseguka njira flowmeters, mapulogalamu omwe ali pamalopo atsimikizira kuti mawonekedwe a mankhwalawa amakwaniritsa zofunikira pakuyezera madzi onyansa ndi kutsimikizira.
