Ukuchaneka kweemitha zokuhamba ze-ultrasonic ezibanjiweyo kuxhomekeke kwizinto ezininzi, kuquka umgaqo wokulinganisa, iimeko zokufakela, iimpawu zolwelo, kunye neempawu zepayipi. Phantsi kweemeko ezifanelekileyo, ezi mitha zichanekile kakhulu kwaye zithembekile, kodwa ukusebenza kwazo kunokwahluka ngokuxhomekeke kwindawo engqongileyo.
Ukuchaneka Okuqhelekileyo
1. Iimitha zokuhamba kwexesha lokuhamba:
• Ukuchaneka: ±0.5% ukuya ku-±1% yokufundwa (phantsi kweemeko ezifanelekileyo).
• Ilungele kakhulu ulwelo olucocekileyo oluneeprofayili zokuhamba kwamanzi ezingaguquguqukiyo.
• Ukuchaneka okuphezulu xa umbhobho ulinganiswe ngokufanelekileyo, kwaye ulwelo lufana.
2. Iimitha zokuhamba kweeDoppler:
• Ukuchaneka: 0.5%-2.0% isikali esipheleleyo
• Ayichanekanga kangako kuneemitha zexesha lokuhamba, njengoko zixhomekeke ekubeni kukho amasuntswana okanye amaqamza kulwelo.
• Ukuchaneka kunokwahluka kakhulu ngokusekelwe kuxinzelelo kunye nokusasazeka kwamasuntswana.
Izinto Ezichaphazela Ukuchaneka
1. Iimpawu zePipe:
• Izinto: Umbhobho kufuneka udlulise kakuhle imiqondiso ye-ultrasonic (umz., isinyithi, i-PVC).
• Ubukhulu bodonga: Kufuneka bulinganiswe ngokuchanekileyo kwaye bufakwe ngexesha lokuseta.
• Imeko: Ukugqwala, ukukrwela, okanye ulwelo ngaphakathi kombhobho kunokuphazamisa isignali.
2. Iimpawu zolwelo:
• Ukucaca: Iimitha zexesha lokuhamba zifuna ulwelo olucocekileyo, ngelixa iimitha zeDoppler zifuna amasuntswana okanye amaqamza.
• Ubushushu: Ubushushu obugqithisileyo bunokuchaphazela ukuhanjiswa kwesignali kwaye bufune imbuyekezo.
• Isantya sesandi: Utshintsho kwisantya sesandi solwelo (umz., ngenxa yotshintsho lobushushu) lunokunciphisa ukuchaneka.
3. Iprofayili yoMsinga:
• Iprofayili yokuhamba kwamanzi ezinzileyo nephuhlileyo ifanelekile. Ukuphazamiseka (umz., okuvela kwiigophe, iivalvu, okanye iimpompo) kunokubangela ukungachaneki.
4. Ufakelo:
• Ukulungelelaniswa ngokufanelekileyo kunye nokubekwa kwee-transducers kubalulekile.
• Iimpazamo kwi-engile yokufakela okanye umgama phakathi kwee-transducers zinokunciphisa ukuchaneka.
5. Ukulinganisa:
• Ukulinganisa okufanelekileyo kusetyenziswa ubungakanani obuchanekileyo bombhobho kunye neempawu zolwelo kubalulekile.
• Iiparameter zokufaka ezingachanekanga ziya kukhokelela kwiimpazamo.
Ukuphucula Ukuchaneka
• Ukulungiswa kwendawo: Qinisekisa ukuba umphezulu wombhobho ucocekile kwaye awunazo iingceba ukuze i-transducer idibane kakuhle.
• Ingqwalasela yeProfayili yokuHamba koMbane: Faka imitha kude ngokwaneleyo kwiingxaki zokuHamba koMbane (umz., ukugoba okanye iivalvu) ukuze ufumane iprofayili yokuHamba koMbane efanayo.
• Ukulinganisa: Lungisa isixhobo rhoqo kwaye uqinisekise iiparameter zokufaka.
• Iimodeli eziPhambili: Sebenzisa iimitha zokuhamba ezisemgangathweni ophezulu ezineenkqubo zokulungisa isignali eziPhambili ukuze usebenze ngcono kwiimeko ezinzima.
Imigangatho yoShishino
Iimitha zokuhamba ze-ultrasonic ezikumgangatho ophezulu ezifakwe kwi-clamp-on ezivela kubavelisi abaziwayo zinokufikelela ngokuchanekileyo okufanayo neemitha zokuhamba ezihambayo. Nangona kunjalo, kwizicelo ezifuna ukuchaneka okuphezulu kakhulu (umz., ukudluliselwa kokugcinwa), iimitha ezihlaselayo okanye ezinye iindlela zobuchwepheshe zihlala zikhethwa.
