Kudivayisi sokulinganisa umoya velocity. amathuluzi Meteorological

Yedivayisi ukulinganisa isivinini komoya kanye isiqondiso nenchazelo eyaziwa ngokuthi igalelo zokubuka noma anemometer. Sebenzisa leli thuluzi, uma kudingekile ukulawula imingcele emoyeni ukunyakaza.

Umgomo we operation

Naphezu ukuhlukahluka anemometers, leyehlukile ikhipha iningi labo ukusebenza isimiso yokunquma ubunjalo isenzo ukugeleza komoya ungene ezihambayo izakhi ligijima.

Amadivayisi kulesi sigaba bayakwazi ukunquma esiphezulu zamanje isivinini somoya kanye ukugeleza umoya indlela ethile. Ezinye izinkomba onobuhle ukunikeza umthamo ukugeleza rate, ukugeleza lokushisa, umswakama. Ngakho, idivayisi obusebenzayo for ukulinganisa isivinini somoya is iguqulwe ibe sezulu esiteshini ephathekayo.

izinhlobo

Thola izinhlobo eziningana ethize amadivayisi ukububala ngokuthe isivinini somoya. Okwamanje, lezi zinhlobo ezilandelayo amadivaysi uya khona:

• ukujikeleza;
• eddy;
• ezishisayo;
• torque engu;
• optical;
• ultrasound.

Ake sihlolisise at uhlobo idivayisi ngamunye, ukucacisa amandla abo, izindlela yokusebenza.

anemometer ukujikeleza

Insimbi Meteorological ingase ifakwe izinkomishi noma izindwani, okuyinto isinyathelo isici njengoba abathola. Kwakamuva removably kuvikelwe ukuba umgodi mpo futhi uxhumeke kwi-imitha. Ukuhambisa komoya kubangela vane ukujikisa mayelana-eksisi ezinjalo. Njengoba ukunyakaza yokulinganisa indlela kuthola inani linemibhikisho for predetermined isikhawu sesikhathi. Imiphumela ezibukwayo Imininingwane umoya isivinini ububanzi, noma ukubonisa digital.

Ezakhiwe yalolu hlobo yasungulwa kudala. Nokho, naphezu ukuvela amathuluzi ezingcono, anemometers ukujikeleza namanje uqhubeke ngempumelelo usebenza ababikezeli bezulu emhlabeni wonke.

vortex anemometers

Ngo zinsizakuphila ijubane nesilinganiso futhi isiqondiso somoya kwenzeka ngenxa yesenzo emoyeni ukusakaza ibe isondo blade ukukhanya achithayo ngonyaka indiza mpo. Njengasendabeni yabase langaphambilini, ukujikeleza impeller ngokwenza uhlelo of amagiya ithumela ukwaziswa indlela esiphikisayo.

Okwamanje, isandla ezivamile vortex anemometers. Lesi sakamuva zisetshenziselwa ukukala komoya amazinga e ukupholisa izinhlelo kanye namapayipi ezifakiwe kumaphrojekthi ezimbonini kanye yokuhlala mapayipi.

anemometers ezishisayo

Hhayi kakhulu ziphoqa amadivayisi ezishisayo. Ngokuvamile, kuba nesidingo kwisicelo sabo e nesilinganiso izinkomba kancane umoya notshwala.

imisebenzi Thermal usheshise inzwa omoya isimiso yokulinganisa lokushisa intambo noma amapuleti ekhethekile, okuyinto umfutho womoya. Nge ezahlukene ukugeleza amazinga lwabelwe ethile amandla evumela ukuthi kulondolozwe izinga lokushisa ethile timphawu ukushisa. Ngale ndlela elula, kanye isivinini somoya kunqunywa.

torque anemometers

Kudivayisi sokulinganisa Isivinini umoya may futhi ukusebenza ngokuhlonza umoya ukugeleza ingcindezi izinkomba uphawu phakathi uhlangothi tube T emise. Idatha etholwe ngesisekelo Ukuqhathanisa ngokweqile umfutho womoya ngaphakathi nangaphandle cell.

Torque kudivayisi sokulinganisa isivinini somoya isetshenziswa hhayi kuphela e-meteorology. Asethwe kumadivayisi ezifana nezinhlelo ukupholisa, Amapayipi, lapho kubalwa a volumetric ukugeleza rate futhi ukugeleza velocity.

anemometers ultrasonic

Umgomo we operation amadivayisi kwalesi sigaba kusekelwe sokunquma ijubane umsindo ngesikhathi umamukeli njengoba umsebenzi emoyeni mass ukugeleza amazinga. Nazi kakhulu ephezulu ukucacisa, amadivayisi eyindida futhi ukuba silungise isiqondiso somoya ukugeleza.

Ukwabela ngakuthathu amadivayisi ultrasonic mgudumbili. Okokuqala unike amandla izibalo ukukhiqizwa kokuqondisa yezokuvakasha igelezela kuzo izingxenye ezintathu. Futhi, ntathu ithuluzi Meteorological kungaba ukukala isivinini somoya kanye endizeni ovundlile. Ezinye izinhlelo ultrasound iveza kuhlaziywa lokushisa airflows.

anemometers optical

Yemvelo, onjiniyela abathintekayo ezinhlelweni isikhala, ngokuvamile baphendukela ekusebenziseni laser amadivayisi optical sokulinganisa isivinini nendlela yekuhambisa sandla air stream. Amadivayisi anjalo usebenza ngokuvumelana nencazelo ukukhanya ezihlakazekile noma kubonakala kusukela velocity ezihambayo into. Le ndlela aluhileli imiphumela ngqo izinto gaseous, okuluketshezi noma okuqinile ithanda zona lezi zici zedivayisi wokulinganisa.

Ububanzi anemometers optical ebanzi kakhulu, kusukela ekutholeni izinkomba ukunyakazisa izinto zibe namangqamuzana aphilayo kanye capillary nesiphetho isivinini ukunyakaza kathisha yamagesi asemkhathini.

Ukusebenza idivayisi laser kwenza kube ngokunembile ukubala Isivinini air logeleta utungelete izinto ezihambayo, ikakhulukazi izimoto, izindiza, emizimbeni isikhala. Izibalo okuholela ukunikeza ithuba abacwaningi, onjiniyela kanye Mechanics ukuklama ukuma sokunciphisa umoya lapho zindiza kakhulu ukwakhiwa imishini.

Amathiphu Ukukhetha

Yini okufanele Ngibheka uma kukhethwa ithuluzi for ukulinganisa isivinini nendlela yekuhambisa sandla air imisinga? Esibalulekile lapha uhlu imisebenzi ebhekene ngumsebenzisi. Kuye lesi silinganiso sibe ezibekiweko of the idivayisi:

• esiphezulu wokulinganisa ububanzi;
• Inani amaphutha;
• kungenzeka kwesicelo ezimweni ezahlukene lokushisa;
• ukuphepha idivayisi umsebenzisi lapho zihlatshwa izici nolaka kwemvelo;
• uthayiphe: kudivayisi umile noma ephathekayo;
• degree of ukuvikelwa indlela kwezulu imithelela;
• uhlobo idivayisi iphinde indlela ugesi idatha;
• Ubukhulu idivayisi;
• kungenzeka ekubaleni izinkomba nasebusuku (khona ukukhanya).

Okwamanje, ukusebenza nemibandela okushisa aphansi kakhulu ingasetshenziswa zomculo Meteorological heater. Ukuze ezimayini ezikhethekile ukusetshenziswa anemometers ukuthi ziyakwazi nokusebenza ngendlela efanele ngesikhathi wokuqukethwe eliphezulu uthuli Isikhala ezungezile endaweni evuthayo. Amadivayisi anjalo obusebenzayo ahlupheke ukuchayeka umswakama ephakeme futhi sihlale operable lapho abalulekile lokushisa nomehluko.

Ngenxa yalokho,

Njengoba singabona, kuye ngezidingo siqu, kungenzeka ukukhetha idivayisi ofanele kakhulu ukulungisa amazinga komoya. Nokho, kukhona ubunzima obuthile. Njengoba zonke anemometers abakumedako amadivayisi, angaphansi isitifiketi futhi isitifiketi yi zikahulumeni efanele.
