Kugwiritsa ntchito kwa doppler flow meter

Pali zinthu zambiri zomwe zimakhudza kuchuluka kwa madzi otuluka. Mwachitsanzo, mapaipi otulutsa madzi otuluka m'mizinda, ngati matope opita kukhoma la mapaipi sali osalala, kuchuluka kwa madzi otuluka kudzatsekedwa ndikuchepetsedwa. Chitoliro chikakhala chachitali, kutayika kwake kumakhala kwakukulu panjira, komanso kuchuluka kwa madzi otuluka kumakhala kocheperako. M'mimba mwake mwa mapaipi otulutsa madzi otuluka sikungakhale kwakukulu kwambiri kapena kochepa kwambiri, chifukwa chachikulu kwambiri chidzawonjezera ndalama zomwe polojekiti ikugwiritsa ntchito, chochepa kwambiri chidzakhudza magwiridwe antchito a madzi otuluka, nthawi zambiri malinga ndi kuchuluka kwa madzi otuluka kuti adziwe kukula kwa mapaipi.

Doppler ultrasonic flowmeter ndi kugwiritsa ntchito mfundo ya ultrasonic Doppler poyesa kuyenda kwa mita, Doppler flowmeter ili ndi zabwino zambiri, sikufunika kudula mofanana ndi sensa yoyika chitoliro cha electromagnetic flow meter, sikufunika kugwiritsa ntchito chipangizo cholumikizira, osanenapo kukhazikitsa malo okhazikika kuti azitha kuyendetsa madzi kuchokera pamalo otuluka, madzi oyera ndi madzi odetsedwa amatha kuyezedwa. Nthawi yomweyo, imatha kuthetsa vuto la "muyeso wa chubu chosakhala chathunthu".

Munda wofunsira:

Kusamalira madzi, maukonde a mapaipi apansi panthaka m'mizinda, ngalande zamadzi otayira m'mizinda, ngalande za mafakitale, madzi otayira m'zipatala, migodi, madzi othirira ulimi, ulimi wa m'madzi, kuzindikira mitsinje yachilengedwe ndi zina zotero.
