1. Ubwino Waukulu wa Zochitika za Chitoliro cha Madzi Oundana
Ma flowmeter a Doppler ultrasoundZimaonekera bwino kwambiri pakugwiritsa ntchito mapaipi a matope makamaka chifukwa cha mphamvu zitatu. Choyamba, kapangidwe kake kosalowerera ndale kumatanthauza kuti palibe zigawo zomwe zimalowa mupaipi, zomwe zimapewa kutsekeka ndi zinthu zolimba zomwe zimayimitsidwa ndi matope (monga grit, organic flocs, kapena ulusi) ndikuchepetsa kufunikira kochotsa ndi kuyeretsa pafupipafupi. Chachiwiri, zimagwirizana bwino ndi zinthu zosiyanasiyana za matope—mosiyana ndi ma electromagnetic meters omwe amalephera ndi matope otsika, kapena ma turbine meters omwe amakhudzidwa ndi turbulence, ma flowmeter awa amangofuna tinthu tomwe timawunikira bwino mu matope kuti tisunge kulondola, ngakhale mitundu ya kukhuthala kwambiri. Chachitatu, ma transducer awo akunja amapangidwa ndi zinthu zosagwira dzimbiri (monga PTFE, ceramic), zomwe zimatha kupirira matope a mafakitale okhala ndi acidic kapena alkaline, zomwe zimawonjezera moyo wawo wautumiki mpaka zaka 8-10, nthawi yayitali kuposa ma meter olowerera.
2. Magawo Ofunika Ogwiritsira Ntchito
Amagwiritsidwa ntchito kwambiri m'magawo atatu akuluakulu okhudzana ndi matope. M'malo oyeretsera madzi otayira m'matauni, amayang'anira kuyenda kwa matope m'magawo ofunikira: panthawi yokhuthala, amathandizira kukulitsa kuchuluka kwa flocculant potsata kulowa kwa matope osaphika; mu kugaya, amawongolera kuchuluka kwa matope osagwiritsidwa ntchito ndi mpweya poyesa kuyenda kwa matope ogayidwa (ngakhale ndi mababu a biogas); mu kuchotsa madzi, amasintha magawo osindikizira poyang'anira matope olowa mu makina osefera—mwachitsanzo, chomera cha Berlin chinawongolera kulondola kwa muyeso kufika pa ±2% ndikuchepetsa kukonza ndi 70% atagwiritsidwa ntchito. Pa matope a mafakitale (monga matope olemera mu ulusi kapena matope a petrochemical oil), amathetsa mavuto otsekeka omwe amavutitsa mita yachikhalidwe, kuonetsetsa kuti ntchito ikugwirabe ntchito. Amathandizanso kugwiritsanso ntchito matope, monga m'mapulojekiti a matope kupita ku biogas, komwe amayesa kuyenda kwa matope ogayidwa kuti akonze chiŵerengero chosakanikirana cha matope ndi zinthu zina, ndikuwonjezera phindu la biogas.
3. Malangizo Ofunikira Okhazikitsa
Kukhazikitsa bwino ndikofunikira kwambiri kuti mutsimikizire kulondola kwa muyeso, ndipo mfundo zitatu ziyenera kudziwika. Choyamba, sankhani gawo la chitoliro cholunjika: kutalika kwa m'mwamba kuyenera kukhala kochepera 10 kuposa m'mimba mwake wa chitoliro, ndipo kutalika kwa m'munsi kuyenera kukhala kochepera 5, kuti mupewe kusokonezeka kwa kayendedwe ka madzi kuchokera ku zigongono, ma valve, kapena mapampu omwe amakhudza kudalirika kwa deta. Chachiwiri, ikani ma transducer molondola: pamapaipi opingasa, ikani 45°–90° pamwamba pa pansi pa chitoliro—izi zimapewa matumba a mpweya (omwe amachititsa kuti chizindikiro chiziwonekere molakwika) ndi kusonkhanitsa kwa zinyalala (zomwe zimaletsa kutumiza kwa zizindikiro); pamapaipi oimirira, onetsetsani kuti matope akuyenda mmwamba kuti tinthu tating'onoting'ono tisungidwe mofanana. Chachitatu, gwiritsani ntchito zinthu zoyenera zolumikizira: sankhani mitundu yotentha kwambiri komanso yosagwira mafuta kuti muwonetsetse kuti kulumikizana kwamphamvu pakati pa ma transducer ndi khoma la chitoliro, makamaka pamapaipi omwe amanyamula matope otentha kwambiri.
Chidule
Ma flowmeter a Doppler ultrasoundNdi abwino kwambiri kugwiritsa ntchito mapaipi a matope, ndi ubwino waukulu woletsa kutsekeka, kusinthasintha kwamphamvu, komanso kukana dzimbiri. Amagwira ntchito yofunika kwambiri pakukonza madzi otayira m'matauni, kuyang'anira matope m'mafakitale, ndi kugwiritsanso ntchito matope, pomwe kuyika bwino (kuyang'ana kwambiri kusankha gawo la mapaipi, malo osinthira, ndi kugwiritsa ntchito othandizira olumikizirana) kumatsimikizira kuti amagwira ntchito bwino komanso mokhazikika. Zinthu izi zimapangitsa kuti zikhale njira yodalirika yothetsera mavuto a kuyeza kuyenda kwa matope.
