Mita ya mulingo wa akupanga

Chida choyezera mulingo wa ultrasonic ndi chida choyezera chosakhudzana ndi madzi chomwe chimayesa mulingo wamadzimadzi kapena zinthu zolimba pogwiritsa ntchito mfundo ya ultrasound reflection. Chili ndi makhalidwe odziwika bwino awa:

1. Muyeso wosakhudzana ndi kusinthasintha kwamphamvu

Sensa siyimakhudzana mwachindunji ndi chinthu choyezedwacho, kupewa mavuto monga dzimbiri, kumatira, ndi kuwonongeka komwe kumachitika chifukwa cha chinthucho. Ndi yoyenera makamaka pa ntchito yovuta kwambiri yokhala ndi kutentha kwambiri, kupsinjika kwakukulu, zinthu zowononga (monga njira zothetsera asidi), zinthu zokhuthala (monga matope), kapena zinthu zokhala ndi tinthu tolimba. Ndi yabwino kwa zinthu zomwe zili ndi zofunikira kwambiri paukhondo (monga mafakitale azakudya ndi mankhwala) ndipo sizingaipitse zinthu.

2. Mitundu yosiyanasiyana ya muyeso komanso kusinthasintha kwakukulu

Muyeso wa zinthu ukhoza kukhala kuyambira masentimita makumi awiri mpaka mamita makumi awiri (kutengera chitsanzo ndi momwe ntchito ikuyendera), zomwe zingakwaniritse zosowa za muyeso wa madzi/muyeso wa zinthu zomwe zimagwiritsidwa ntchito m'mafakitale ambiri (monga matanki osungiramo zinthu, ma kettle ochitira zinthu, maiwe, malo osungiramo zinthu, ndi zina zotero). Njira yoyikira ndi yosinthasintha. Ikhoza kuyikidwa pamwamba kapena mbali ya chidebecho kudzera mu bulaketi popanda kulowa mkati mwa sing'anga, zomwe zimapangitsa kuti kapangidwe kake kakhale kosavuta.

3. Kuyankha mwachangu komanso kugwira ntchito bwino nthawi yeniyeni

Zizindikiro za ultrasonic zimafalikira mofulumira kwambiri (pafupifupi 340m/s mumlengalenga) ndi kuzungulira kwakanthawi kochepa koyezera (nthawi zambiri mu ma millisecond), komwe kumatha kuwonetsa kusintha kwamphamvu kwa mulingo wazinthu munthawi yeniyeni. Ndikoyenera kuyang'anira kusinthasintha kwachangu kwa mulingo wamadzimadzi/mulingo wazinthu (monga makina odzaza, ma silo osinthika, ndi zina zotero).

4. Ntchito yosavuta komanso yotsika mtengo yokonza

Palibe chifukwa chogwiritsira ntchito makina ovuta, ndipo njira yowerengera ndi yosavuta (mitundu ina imathandizira kuwerengera kiyi imodzi). Kukonza pambuyo pake kumafuna kuyeretsa nthawi zonse kwa sensor probe kuti fumbi ndi nthunzi yamadzi zisakhudze kutumiza kwa chizindikiro, zomwe zimapangitsa kuti pakhale ndalama zochepa zokonzera. Mitundu yambiri ili ndi zowonetsera za digito kapena ma interface olumikizirana (monga 4-20mA, RS485), zomwe zimatha kuwerenga deta mwachindunji kapena kulumikizana ndi makina owongolera kuti ziwonekere mosavuta patali.

5. Sizikhudzidwa ndi zinthu zakuthupi za sing'anga

Zotsatira za muyeso sizimakhudzidwa ndi makhalidwe enieni a chinthu chogwiritsidwa ntchito monga kuchulukana, kukhuthala, kusinthasintha kwa mpweya, ndi kutentha (mkati mwa mtunda winawake, kubwezera kutentha kumafunika). Bola ngati pamwamba pa chinthucho pakhoza kuwonetsa bwino mafunde a ultrasound, muyeso wokhazikika ukhoza kuchitika.

6. Zoletsa ndi njira zodzitetezera

Zimakhudzidwa ndi zinthu zachilengedwe:

Mafunde a ultrasound amafalikira mumlengalenga. Ngati pali mafunde amphamvu a mpweya, fumbi, nthunzi, thovu, kapena zopinga mu chidebe (monga zosakaniza), zingayambitse kusokonezeka kwa chizindikiro, zomwe zimakhudza kulondola kwa muyeso kapena kupangitsa kuti chilephereke.

Zofunikira zazikulu pa mawonekedwe:

Pamwamba pa malo oyezedwawo payenera kukhala pathyathyathya (monga madzi osasinthasintha). Ngati ndi pamwamba pa madzi osinthasintha kwambiri kapena pamwamba pa tinthu tolimba (monga ufa silo), zolakwika zingachitike chifukwa cha zizindikiro zofooka zomwe zimawonetsedwa.

Kuchepetsa kutentha:

Malo otentha kwambiri (monga kupitirira 80°C) angayambitse kusintha kwa kuchuluka kwa mpweya, zomwe zimakhudza liwiro la mafunde a phokoso. Ndikofunikira kusankha mitundu yokhala ndi ntchito zochepetsera kutentha kwambiri.

Ubwino waukulu wa zoyezera mulingo wa ultrasonic ndi kusakhudzana, kukana dzimbiri, kusavuta kuyika ndi kukonza, komanso kugwiritsa ntchito zinthu zosiyanasiyana. Ndi zipangizo zomwe zimagwiritsidwa ntchito kwambiri poyezera mulingo wamadzi/zinthu m'mafakitale. Komabe, posankha, chisamaliro chiyenera kuperekedwa kuti chipewe kukhudzidwa ndi chilengedwe (monga fumbi, nthunzi) ndi momwe zinthu zilili pamwamba pa sing'anga. Ngati pakufunika kutero, zipangizo zothandizira (monga ma waveguides) kapena zitsanzo zapadera (monga zitsanzo zoteteza kuphulika, kutentha kwambiri) ziyenera kugwiritsidwa ntchito kuti zigwirizane ndi zovuta zogwirira ntchito.
