Yokulinganisa uxinzelelo yokulinganisa

yokulinganisa uxinzelelo - isixhobo (amacebo) ukwenzela parameters umlinganiselo yengcinezelo igesi, engamanzi. Devices zihlelwa ngeentlobo eziliqela, kuxhomekeka iimpawu. Phambi kokuba ukhetha i manometer umlinganiselo ukuba uxinzelelo, kufuneka ufunde ezi nkcukacha lokusetyenziswa kwazo.

Ukukhetha isixhobo ngokutsho uluhlu loxinzelelo kulinganiswa

- Pressure gauge. Isixhobo ukulinganisa engumahluko onguphozithivu phakathi xi ingundoqo kunye noxinzelelo womoya kuluhlu ukususela 0,06 ukuya 1000 MPA.

- ulinganisa. Amanyathelo ongenawo kude 40 kPa.

- Umshini. Inceda yokulinganisa uxinzelelo ngezantsi kokugquma (esesibhakabhakeni) ukuya ku-100 kPa.

- ulinganisa. Amanyathelo kancinane uxinzelelo kwemfuneko (40 kPa).

- ulinganisa. Umlinganiselo uchunge elungelelene kwekhefu ukusuka - 20 ukuya + 20 kPa.

- manometers. Oku kuquka soxinzelelo lwegazi yokulinganisa uxinzelelo kwemfuneko (60 ukuya 240000 kPa), kunye lwepolitiki (ukuya kwi - 100 kPa).

- uxinzelelo umehluko gauge. Le fowuni ilungiselelwe umlinganiselo uxinzelelo umahluko.

Ibisetyenziswa kakhulu zomculo zahlula kunye noxinzelelo epheleleyo. isixhobo umahluko (izxhobo) yokulinganisa umahluko ingcinezelo phakathi amaxabiso amabini kubonisiwe. manometers ingundoqo abonisa ixabiso koxinzelelo, kungakhathaliseki ukuhla kwi-atmosfera.

Iimpawu, izakhiwo manometers

Yokulinganisa sokulinganisa xi zohlulwa ngokwendidi eziliqela, ngokuxhomekeke kuyilo nolwakhiwo imveliso: ulwelo, deadweight, inwebu deformation, lo deformation ukuya kumthombo tubular (Bourdon tube). Iinkcukacha yenza ukulinganisa amandla aphezulu elithile ngokuchanileyo.

soxinzelelo lwegazi uvalo kusetyenziswa amayeza. Zezona kakhulu abahlambulukileyo ngokoMthetho zokusingqongileyo, umgangatho i mercury ayithanga kratya.

Kuyinto yokulinganisa eqhelekileyo kakhulu yokulinganisa uxinzelelo igesi. Ziqulethe uluhlu umzimba apho kukho iimitha. Izixhobo ezifakwe kwi compressors, iimpompo, izixhobo igesi. yokulinganisa gesi ichanekile ukufundwa.

Yokulinganisa naluphi na uhlobo zihlelwa ngokungqinelana ekuchanekeni indicators. I ezincinane inani, sisixhobo ubonisa ixabiso elichanekileyo ngakumbi. Iiklasi nokuchaneka zezi zilandelayo: 0,15; 0.25; 0.4; 0.6; 1.0; 1.5; 2.5; 4.0.

yokulinganisa scope

Nenjongo yokulinganisa ezininzi. Baya kuza qha yombane, jikelele zobugcisa, reference, rekhoda, injongo ekhethekileyo.

- electric manometer zomfowunelwa kusetyenziswa ukulawula kunye nomlinganiselo xi ingangumoya, bume lulwelo, non-entsimbini.

- yokulinganisa Obshchetehnichesky esetyenziselwa ukulinganisa umphunga uxinzelelo, igesi, engamanzi.

- yokulinganisa Reference izinga accuracy eliphezulu. Iveza uvavanyo kunye umlinganiselo kwimibhobho kwezinye izixhobo. Ngokubanzi, nanzo efakwe kwi deadweight kwefowuni.

- yokulinganisa Ingcinezelo kunye yokufunda xi recorder busisigxina kwindlela ekhethekileyo yenethiwekhi.

- yokulinganisa Ingcinezelo ukulungiselela iinjongo ezikhethekileyo zinika iimeko ezinqwenelekayo kwezendalo. Ezi ziquka: oksijini (blue), iasithilini (abamhlophe), hydrogen (blue-green) Izixhobo. imibala eyahlukileyo efunekayo ukuze siphephe imiphumo emibi. Umzekelo, izixhobo ioksijini kufuneka degreased, okanye ezingcolisekileyo kwisixhobo wadibana oksijini olunyulu dubulo.

Pressure gauge yokulinganisa uxinzelelo amafutha zingasetyenziswa-mveliso eyahlukeneyo. Xa ukhetha icebo, ufanele wazi ukuba imveliso esemgangathweni zingathengwa kuphela evela kumenzi obekekileyo kunye negama ehlabathini lonke. Umenzi kufuneka abe nephepha-mvume ngenxa yokumpompoza iimpahla, isiqinisekiso yomgangatho. Le nto ibaluleke kakhulu. Emva izixhobo ezisetyenziswa kwiinkqubo zobugcisa kunye nemveliso ezintsonkothileyo. Kwaye amisele ukhuseleko ngenkqubela kunye nomgangatho imveliso yokugqibela.
