Intshayelelo

Elimitha yamanzi e-ectromagnetic luhlobo lwesixhobo sokulinganisa ukuhamba kwevolumu yolwelo oluqhubayo olusekwe kumgaqo kaFaraday wokungeniswa kombane. Ineempawu zoluhlu olubanzi, ukuhamba okuphantsi kokuqala, ilahleko yoxinzelelo oluphantsi, umlinganiselo wexesha lokwenyani, umlinganiselo owongezelekayo, umlinganiselo we-bi-direction, njl. njl. Ubukhulu becala isebenzisa ucando lwe-DMA, ukubeka iliso kwi-intanethi, ukuhlalutya ilahleko yamanzi kunye nokuhlaliswa kweenkcukacha-manani kwiindawo zonikezelo lwamanzi. .

Iingenelo

I-1 Akukho zithintelo ngaphakathi kwityhubhu yokulinganisa, ukulahleka koxinzelelo oluphantsi kunye neemfuno eziphantsi zombhobho othe ngqo.
2 Uyilo lwedayamitha eguquguqukayo, phucula ukuchaneka komlinganiso kunye novakalelo, ukunciphisa ukusetyenziswa kwamandla okuvuselela.
3 Khetha ii-electrode ezifanelekileyo kunye ne-liner, enokumelana nokugqwala okuhle kunye nokumelana nokunxiba.
I-4 Uyilo olupheleleyo lwe-elektroniki, amandla okumelana nokuphazamiseka, ukulinganisa okuthembekileyo, ukuchaneka okuphezulu, uluhlu olubanzi lokuhamba.

Isicelo

Imitha yamanzi yombane sisixhobo sokulinganisa esilungiselelwe ngokukodwa iimfuno zokwenyani zamashishini onikezelo lwamanzi, eyenzelwe ngokukodwa ishishini lamanzi, elinokwandisa unikezelo lwamanzi kunye nokuqinisekisa umlinganiselo ochanekileyo worhwebo lwamanzi kunye nokuhlaliswa. Ukuziqhelanisa kubonakalise ukuba imitha yamanzi ye-electromagnetic lolona khetho lufanelekileyo lokusombulula ukuchasana komlinganiselo wabasebenzisi bamanzi abakhulu. Ukongeza, iimitha zamanzi ze-electromagnetic zisetyenziswa kakhulu kwishishini lemichiza, ukhuseleko lokusingqongileyo, isinyithi, amayeza, ukwenza iphepha, unikezelo lwamanzi kunye nokukhupha amanzi kunye nobunye ubuchwephesha boshishino kunye namasebe olawulo.

Ukufakela

Ukhetho lwemekobume yofakelo
1. Hlala kude nezixhobo ezinamasimi anamandla e-electromagnetic. Ezinje ngemoto enkulu, i-transformer enkulu, izixhobo ezinkulu zokuguqula amaza.
2. Indawo yokufakela akufanele ibe ne-vibration enamandla, kwaye ukushisa kwe-ambient akutshintshi kakhulu.
3. Ilungele ukufakela kunye nokugcinwa.

Ukukhethwa kwendawo yokufakela
1. Uphawu lwesikhokelo sokuhamba kwi-sensor kufuneka luhambelane nolwalathiso lokuhamba kwendlela yokulinganisa kwipayipi.
2. Isikhundla sokufakela kufuneka siqinisekise ukuba ityhubhu yokulinganisa isoloko igcwele i-medium medium.
3. Khetha indawo apho i-fluid flow pulse incinci, oko kukuthi, kufuneka ibe kude nempompo yamanzi kunye neendawo zokuchasana zendawo (iivalve, i-elbows, njl.)
4. Xa ulinganisa ulwelo olunezigaba ezibini, khetha indawo ekungelula ukubangela ukwahlukana kwesigaba.
5. Gwema ukufakwa kwindawo enoxinzelelo olubi kwi-tube.
6. Xa isilinganisi esilinganisiweyo sibangela ukuba i-electrode kunye nodonga lwangaphakathi lwetyhubhu yokulinganisa lunamathele kunye nokulinganisa, kucetyiswa ukuba izinga lokuhamba kwi-tube yokulinganisa lingabi ngaphantsi kwe-2m / s. Ngeli xesha, ityhubhu edibeneyo incinci kancinci kunetyhubhu yenkqubo ingasetyenziswa. Ukuze uhlambulule i-electrode kunye ityhubhu yokulinganisa ngaphandle kokuphazamisa ukuhamba kwi-tube yenkqubo, inzwa inokufakwa ngokuhambelana nechweba lokucoca.

Iimfuno zecandelo lombhobho othe tye
Iimfuno zenzwa kwicandelo lombhobho othe tye onyukayo ziboniswe kwitheyibhile. Xa iidayamitha zamacandelo emibhobho enyukayo nasezantsi ethe ngqo engahambelani naleyo yemitha yamanzi abandayo ye-electromagnetic, kufuneka kufakwe umbhobho ocociweyo okanye umbhobho obhinqiweyo, kwaye i-Angle yawo ecoko kufuneka ibe ngaphantsi kwe-15° (7° -8 °). ekhethwayo) kwaye emva koko idityaniswe nombhobho.
