Kuyeza mulingo wosakhudzana ndi chinthu chimodzi chofunikira kwambiri pamakina oyendetsera mafakitale. Njirayi imalola kuwunika mulingo wamadzimadzi kapena wolimba mu thanki, chidebe kapena njira yotseguka popanda kuyanjana ndi sing'anga. Njira zina zomwe zimagwiritsidwa ntchito kwambiri zosakhudzana ndi chinthu ndi ma ultrasound ndi ma radar level meters. Ngati wogwiritsa ntchito akufuna kugwiritsa ntchito muyeso wosakhudzana ndi chinthu pakuwongolera mulingo, kumvetsetsa momwe ma ultrasound ndi ma radar level gauges amagwirira ntchito kumathandiza kusankha moyenera pazochitika zinazake.
Mfundo yogwirira ntchito
Ma geji a ultrasonic levelZimagwira ntchito potulutsa mafunde amphamvu kwambiri kuti zipeze kusiyana pakati pa sensa ndi pamwamba pa chinthu chamadzimadzi/cholimba. Mafunde awa amayenda mumlengalenga, amawonetsa pamwamba pa chinthucho, ndikubwerera ku sensa. Mtunda ukhoza kudziwika ndi nthawi yomwe mafunde amathera paulendo wawo. Chifukwa chake chipangizocho chimayikidwa patali pamwamba pa malo apakati, popanda gawo lililonse kukhudzidwa mwachindunji kapena kumizidwa mu chinthucho.
Ma geji a radarimagwiritsa ntchito mafunde amagetsi (ma microwave) m'malo mwa phokoso kuti idziwe mulingo wapakati wa madzi kapena olimba. Mofananamo zizindikiro za microwave zimatulutsidwa kupita pamwamba pa sing'anga kenako zimawonetsedwa ndikubwezeredwa ku chida. Panthawiyi palibe kukhudzana kwenikweni pakati pa thupi la chida ndi sing'anga. Kudzera mu nthawi yolemba nthawi youluka kwa zizindikiro za mafunde, mtunda kuchokera pa chida kupita pamwamba pa chinthucho ukhoza kuwerengedwa.
Miyeso ya milingo ya mitundu iwiriyi imagawana njira zomwezo:
D = (C*T)/2
L = H - D
Kumene,
D: Mtunda kuchokera pamwamba pa sing'anga kupita ku chida
C: Liwiro la mawu (la ultrasound) liwiro la kuwala (la radar)
T: Nthawi yopuma kuchokera pa mpweya woipa mpaka kufika pa kulandira
L: Mulingo wapakati woti muyesedwe
H: Kutalika kuchokera pansi pa chotengera kupita ku chida
Mosiyana ndi zida zodziwika bwino zogwiritsira ntchito pokhudzana ndi zinthu, kuchotsa kukhudzana kwenikweni ndi chinthucho, ukadaulo wa ultrasound ndi radar umapambana kwambiri pakulamulira mulingo wa zinthu zowononga, zokhuthala, kapena zoopsa zomwe zingawononge kapena kutsekereza zinthu zonyowa monga ma floats, ma probe, kapena mizere ya impulse. Kukhazikitsa kumakhala kosavuta chifukwa zipangizozi zimayikidwa kunja ndipo nthawi yosamalira ndi nthawi yopuma nthawi zambiri imakhala yochepa chifukwa cha kapangidwe kake kosavulaza. Makampani monga kukonza mankhwala, kukonza madzi, komanso kupanga chakudya amatha kupindula kwambiri ndi masensa a ultrasound ndi radar osakhudzana ndi mulingo chifukwa cha kusinthasintha kwawo komanso kudalirika kwawo pakati pa zowongolera zamadzimadzi, madzimadzi, matope, ndi olimba m'ma geometri osiyanasiyana a thanki.
Kuyerekeza pakati pa ultrasound ndi radar
Choyezera cha ultrasound ndi chosavuta kuyika ndipo chimafuna kukhazikitsidwa kochepa. Poyerekeza ndi choyezera cha radar, choyezera cha ultrasound nthawi zambiri chimakhala chotsika mtengo ndipo motero chimakondedwa kwambiri mu ntchito zomwe zili ndi ndalama zochepa. Komabe, magwiridwe antchito a zida za ultrasound amakhudzidwa kwambiri ndi zotsatira zachilengedwe za fumbi, thovu, kugwedezeka kwa mpweya komanso kutentha kwambiri ndi chinyezi zomwe zimatha kuyamwa kapena kuletsa mafunde a phokoso ndikuyambitsa vuto la mafunde otayika.
Komano, radar level gauge imadziwika ndi kulondola kwambiri, kutalika kwa nthawi yayitali komanso kudalirika kotsimikizika m'malo ovuta kugwira ntchito. Sichikhudzidwa kwambiri ndi zinthu zomwe zimavuta ukadaulo wa ultrasonic. Komabe zikutanthauza kuti zinthu za radar nthawi zambiri zimakhala zodula kwambiri. Dielectric constant ndi chinthu china chofunikira poyesa radar. Zipangizo zochepa za dielectric zimatha kufooketsa kuwunikira kwa chizindikiro cha echo zomwe zimapangitsa kuti muyeso usakhazikike kapena kutayika.
Mwachidule, wogwiritsa ntchito akasankha kugwiritsa ntchito muyeso wosakhudzana ndi kukhudzana, sensa ya ultrasound ingakhale yabwino kwambiri pa ntchito yocheperako komanso yoganizira bajeti pomwe radar imakhala yoyenera pa malo ovuta komanso kufunafuna muyeso wapamwamba. Mulimonsemo, ndikofunikira kudziwa kuti mawonekedwe apakati ndi chilengedwe, komanso kapangidwe ka njira yogwirira ntchito, ndizothandiza pakukhazikitsa njira yoyezera yopanda kukhudzana.
Zolemba zoyika zida zopanda kukhudza
- ✦ Malo oikirapo ayenera kukhala kutali kwambiri ndi komwe phokoso limachokera
- ✦ Gasket ya rabara ingagwiritsidwe ntchito poyiyika pamalo ogwedezeka
- ✦ Mtunda kuchokera ku sensa kupita ku mulingo wapamwamba kwambiri woyembekezeredwa uyenera kukhala waukulu kuposa malo osawona
- ✦ Malo a sensa ayenera kukhala ndi mtunda winawake ndi khoma la chidebe malinga ndi ngodya yotulutsira
- ✦ Malo oyezera ayenera kukhala opanda zopinga zomwe zingayambitse kusokonezeka kwa zizindikiro monga makwerero kapena mtanda wopingasa.
- ✦ Kuti muyeze bwino pakati, malo oikirapo ayenera kupewa malo otsegulira chakudya cha zinthu.
- ✦ Ndi bwino kupewa kusinthasintha kwakukulu kwa kutentha pamalo oyika zida
- ✦ Choyezera cha sensor chiyenera kukhala cholunjika pamwamba pa sing'anga kuti chigwire bwino ntchito
Shanghai Wangyuanndi kampani yodziwa bwino ntchito yopanga zida kwa zaka zoposa 20 yomwe imapereka masensa a ultrasound ndi radar osakhudza komanso mitundu ina ya zida zoyezera mulingo. Chonde musazengereze kutifunsa mafunso anu okhudza zinthu zoyezera mulingo wosakhudzana.
