Yiziphi izinhlobo zokulinganisa ingcindezi?

1. Indlela yekholomu ewuketshezi

Lezi zinhlobo zezinto zokusebenza zilinganisela ingcindezi elinganisiwe nengcindezi ekhishwa ikholomu yoketshezi. Uma ukuminyana koketshezi kwaziwa, ukuphakama kwekholomu ye-liquid kuyisilinganiso sokucindezela.

2. Isilinganiso somfutho

I-manometer isekelwe endleleni yekholomu ye-liquid futhi ingasetshenziswa ukukala ukucindezela koketshezi. Ngokusekelwe esimisweni sokulinganisa ikholomu ye-liquid ngamakholomu afanayo noma amanye ama-liquid, idivayisi ingahlukaniswa ibe izinhlobo ezimbili: i-manometer elula kanye ne-manometer ehlukile. I-manometer elula i-manometer ekala ingcindezi endaweni ethile oketshezini oluqukethwe epayipini noma esitsheni, futhi i-manometer ehlukile ikala umehluko wengcindezi phakathi kwanoma yimaphi amaphuzu amabili oketshezini oluqukethwe epayipini noma esitsheni. Ama-gauge okucindezela abonakala ngokuzinza kwawo kwamakhemikhali aphezulu, i-viscosity ephansi, i-capillary engaguquki, i-volatility ephansi kanye nomfutho we-vapor ophansi.

3. Indlela ye-elastic element

Idivaysi yokulinganisa ingcindezi yento enwebekayo ibhekisela esisetshenziswa lapho ingcindezi elinganisiwe idala ukuthi izinto ezinwebekayo zigxumeke phakathi kwemikhawulo yazo enwebekayo, futhi ubukhulu bokuguqulwa bucishe bulingane nengcindezi esetshenzisiwe.

4. Uhlobo lwe-diaphragm

Izakhi ze-diaphragm zingahlukaniswa zibe izinhlobo ezimbili, eyokuqala iyisici esisebenzisa izici ezinwebekayo ze-diaphragm, kanti eyesibili iyingxenye ephikiswa yiziphethu noma ezinye izinto ezinwebekayo ezihlukene. Elokuqala liqukethe i-capsule eyodwa noma ngaphezulu, futhi i-capsule ngayinye iqukethe ama-diaphragm amabili axhunywe ndawonye nge-soldering, i-brazing noma i-welding. Izinsimbi ezivame ukusetshenziswa ezingxenyeni ze-diaphragm ziyithusi, ithusi le-phosphor nensimbi engagqwali. Uhlobo lwesibili lwe-diaphragm lusetshenziselwa ukucindezela ingcindezi nokusebenzisa amandla kusici esihlukile sokunwebeka, futhi i-diaphragm izovumelana nezimo. Ukunyakaza kwe-diaphragm kuvinjelwa intwasahlobo, enquma ukuphambuka ekucindezelweni okunikeziwe.

5. Izinzuzo kanye nokusetshenziswa kohlobo lwe-diaphragm

Isetshenziselwa ukulinganisa ingcindezi ephansi kakhulu, ivacuum noma ingcindezi ehlukile. Ngokuvamile zisetshenziswa ezindaweni ezonakalisa kakhulu. Izinzuzo zabo zibucayi kakhulu, zingakwazi ukukala umehluko wengcindezi ngokwengxenye ebangeni elincane kakhulu futhi zidinga indawo encane kuphela.

6. I-Borden gauge yokucindezela

Umqondo ongemuva kwedivayisi ukuthi uma ikhubazekile nganoma iyiphi indlela, ithubhu eliphambanayo lizobuyela esimweni salo esiyindilinga ngaphansi kwengcindezi. Ngokuvamile, amapayipi agotshwa abe yi-C-shape noma ubude be-arc obungaba ngu-27 degrees. I-Bourdon tube ingasetshenziselwa ukulinganisa umehluko wengcindezi ebangeni eliphezulu kakhulu. Igeji ye-Bourdon nayo ingenziwa ibe yifomu elivunguzayo noma elivunguzayo ukuze kutholwe umugqa ongcono kanye nokuzwela okuphezulu. Izinto ze-Bourdon tube kumele zibe nokunwebeka okuhle noma izici zasentwasahlobo.
