Yintoni lesikali? Pressure gauge uxinzelelo yokulinganisa

Ngokufuthi, isigqibo entsimini iingxaki physics nazo izixhobo ezifana, ezifana soxinzelelo lwegazi. Kodwa yintoni na gauge, kusebenza yaye ziziphi iintlobo kukho indlela? Le ntetho namhlanje.

Sinalo gauge xi a?

Esi sixhobo senzelwe ukuba umlinganiselo uxinzelelo yobu-. Noko ke, uxinzelelo zinokuba nomahluko, ngoko kukho into yokulinganisa ezahlukeneyo. Umzekelo, ukuba umlinganiselo iigeji womoya izakusetyenziswa ukugqiba umahluko xi esetyenziswa yi usebenzsa xi umahluko. Kodwa nayiphi na imeko, ukuba umlinganiselo nje ingcinezelo.

Ngoku ke akunakwenzeka ukuba ukuchaza bonke ukusetyenziswa kwezi izixhobo, ngokuba eninzi kubo. Ukuba ingasetyenziswa kwicandelo leemoto, ezolimo, zikamasipala kunye nendawo zokuhlala, kulo naluphi uthutho ngomatshini, yokunyibilikisa isinyithi, njl Kuxobekeka kwezo njongo, kukho iindidi ezahlukeneyo data izixhobo zokulinganisa, kodwa ubuntu babo lusoloko lincitshiswe ukuya kwenye - ukulinganisa uxinzelelo.

Kwakhona, ezi zixhobo bohlulwa babe ngamaqela ahlukeneyo ngokuxhomekeke kumgaqo womlinganiselo. Ke kaloku, ukuba ngaphezulu okanye kwacaca ngaphantsi ukuba onjalo gauge xi, Unokuqhuba kwiinkcukacha. Ngokukodwa, sichaza iintlobo kunye izicelo zabo.

Types of soxinzelelo lwegazi

Kuxhomekeka khona, iigeji kontanga kungaba kweentlobo ezahlukeneyo. Umzekelo, soxinzelelo lwegazi ulwelo esetyenziselwa ukulinganisa column ulwelo xi. Kukho izixhobo yasentwasahlobo sokukala lisetyenziswa amandla. Apha, xi ibalwa ngokusebenzisa wokulungelelanisa namandla deformation emthonjeni.

yokulinganisa ukubana ethandwayo kangako ukuze zikhankanyiwe, apho uxinzelelo kulinganiswa kulinganiswa ngumsebenzi wonyanxelo aye kwi iyunithi piston.

Kwakhona qaphela ukuba ngokuxhomekeke injongo kunye nemiqathango yokusetyenziswa esikhutshwe izixhobo zilandelayo:

• Technical - jikelele-injongo isixhobo.
• Uvavanyo yakhelwe ukuhlola izixhobo efakiweyo.
• Esihle - nezixhobo zovavanyo zomlinganiselo, eyayifuna ukwanda nokuchaneka.

Kwakhona, ezi zixhobo kufuneka zahlulwe iseli uvakalelo, iiklasi ngokuchanileyo. Umzekelo, usebenzsa iklasi accuracy zezi: 0,15, 0.25, 0.4, 0.6, 1, 1.5, 2.5, 4. Apha, inani imisela ukuchana isixhobo, nendlela iya kuba ngaphantsi, isixhobo ngokuchanekileyo.

Ezi gages zenzelwe ukuba umlinganiselo uxinzelelo yobu-. Umgaqo sayo isekelwe phezu ukusetyenziswa ngumthombo okhethekileyo, nto leyo deforms phantsi koxinzelelo. Ixabiso uhlobo element ezibuthathaka () intwasahlobo umiselwa isixhobo ukufunda okhethekileyo, nto leyo iba isikali izidanga. Kweli isikali, umsebenzisi ubona ixabiso yengcinezelo kulinganiswa.

Into zibuthathaka izxhobo zokulinganisa lwenziwa ebizwa ngokuba yi-Bourdon ityhubhu - esisodwa turn entwasahlobo. Nangona kunjalo, kukho ezinye izinto: iflethi inwebu multiturn tubular imfutho yasentwasahlobo incence (garmonikoobraznaya ndizayo). Bonke bephela zisebenza ngokulinganayo, kodwa elula kakhulu kwaye zifikeleleka, yaye ngenxa yoko, aziwayo kakhulu igeyiji ebonisa uxinzelelo ngokujika enye Bourdon entlakohlaza. imifuziselo ezinjalo asetyenziswa ngokubonakalayo zokulinganisa uxinzelelo kwi uluhlu 0.6-1600 kg / cm ^2.

lulwelo-column yepresha

Ngokwahlukileyo emthonjeni, uxinzelelo ulwelo kwi soxinzelelo lwegazi kulinganiswa wokulungelelanisa ubunzima kumhlathi ulwelo, njengoko umlinganiselo uxinzelelo kulo mzekelo - ngumphakamo ulwelo nasezimpahleni ukunxibelelana. izixhobo ezinjalo ukuvumela ukuba umlinganiselo xi kuluhlu ka 10-105 Pa, kwaye zisetyenziswa ikakhulu elabhoratri.

Enyanisweni, isixhobo onjalo - ityhubhu ezimile-U kulwelo kunye benokundileka ephakamileyo ethile ngaphezu kulwelo ngqo xi hydrostatic ulinganiswa. Kwiimeko ezininzi, ulwelo enjalo mercury.

Kolu luhlu ekunokuthiwa izixhobo ngokungathanga ngqo jikelele zobugcisa kunye yokusebenza ezifana Xhosa-510 gauge, TV-510, ezimele udidi kakhulu eceliweyo. Bakala yengcinezelo umphunga non-crystallizable and non-ndlongondlongo kunye neegesi. Class of ukuchana soxinzelelo lwegazi: 1, 2.5, 1.5. Isicelo boilers ezinjalo kwiinkqubo zokufudumeza, xa ezithutha ulwelo, kunye neenkqubo zoshishino.

soxinzelelo lwegazi, contact Electric

Olu didi lubandakanya kuquka usebenzsa emoyeni kunye manometers. Injongo yokulinganisa uxinzelelo iziselo kunye ngeegesi yokuba ngokunxulumene ngentsimbi nobhedu. Uyilo zezi zixhobo ezifanayo emthonjeni, kodwa umahluko ilele kuphela imilinganiselo ezinkulu yemigca. NezeZindlu manometer zoqhagamshelwano yombane enkulu izixhobo yamaqela zoqhagamshelwano. Kwakhona, isixhobo esinjalo ukuba lungakhuseleki kwi uxinzelelo kwindawo kulawulwa ngapha nabo wokuvala / osekuqaleni.

Ngenxa indlela zoqhagamshelwano ekhethekileyo zombane, nesetyenziswa apha, iyunithi ingasetyenziswa kwinkqubo alarm. Enyanisweni, kule ndawo yokuba nayo kusetyenziswa.

Olu hlobo kwezixhobo yenzelwe ukukhangela usebenzsa uxinzelelo ezisetyenziswa imilinganiselo elebhu. Owona msebenzi wabo - iitsheki ukufundwa of ulinganisa zokusebenza. A isici esasenza ezi zixhobo - kwiklasi eliphezulu kakhulu okuchaneka, nto leyo kufikelelwe ngenxa iimpawu zoyilo, kwakunye izinyo kwi indlela okuphucula.

ezizodwa

Olu didi izixhobo ezisetyenziswa mveliso eyahlukeneyo yokulinganisa xi neegesi ezifana ammonia, hydrogen, ioksijini, iasithilini, njl Kwiimeko ezininzi, imilinganiselo gauge ezizodwa kunokwenzeka uhlobo olunye kuphela yigesi. Kuba abanjalo manometer nganye igesi kubonisiwe uhlobo, nekuyinjongo ukulinganisa uxinzelelo. Kwakhona silinganise ngokwakhe zipeyintwe umbala elingqinelana umbala igesi apho sixhobo yenzelwe. Ukonyulwa ifowuni ukwasebenza ileta ethile. Umzekelo, iigeji ammonia usoloko ezinemibala in yellow, achazwa unobumba A kunye nokumelana kubulawa.

Kukho lokungcangcazela-ubungqina izixhobo ezikhethekileyo ezisebenza iimeko kwamaza nehigh okukufutshane kunye nongcangcazelo ngokugqithiseleyo. Ukuba kwiimeko ezinjalo basebenzisa yepresha eqhelekileyo, ixesha elide akazange ukukhonza ngenxa gear ngokukhawuleza nakanjani. Eyona bemfuno lokungcangcazela-gauge - uphawu kunye istili emelana nokudliwa ngumhlwa.

ukurekhoda

Umahluko omkhulu phakathi kwezi ulinganisa igama. Ezi zixhobo xi ngokuqhubekayo kulinganiswa irekhodwa kwi itshathi, ukuze kamva ivumela ukubona igrafu utshintsho xi ngexesha lekhefu elithile. izixhobo ezinjalo asetyenziswa kubunjineli amandla kunye noshishino ukuze umlinganiselo wentsebenzo reception bume ezingezo-entsimbini.

umkhumbi

Ezi zenzelwe umlinganiselo uxinzelelo ongenawo iigesi, umphunga kunye ulwelo (i-oyile, i-diesel, amanzi). izixhobo ezinjalo aphezulu ubumanzi ubungqina, ukumelana kwiimpembelelo zemozulu kunye intlokoma. Njengoko igama libonisa, sinako ukuqonda intsimi yabo yesicelo - lomlambo kunye nothutho ulwandle.

kaloliwe

Ngokungafaniyo soxinzelelo lwegazi eqhelekileyo ebonisa ixabiso uxinzelelo, izixhobo kaloliwe engaveli, kwaye luguqula uphawu xi ngolunye uhlobo (yedijithali, womoya, njalo njalo). Ukulungiselela le njongo, zinokusetyenziswa ngeendlela ezahlukahlukeneyo.

transducers uxinzelelo ezo ngokubanzi kusetyenziswa ukulawula inkqubo, isilawuli esizisebenzelayo, yaye, nangona igama layo ngqo, ezithi zisetyenziswe kwiinkalo ioli, imichiza, kunye namandla enyukliya.

isiphelo

Pressure wemilinganiso kufuneka kumashishini amaninzi, yaye ngamnye kubo, kukho izxhobo ezikhethekileyo kunye neempawu ezizodwa. Kukho nkqu izxhobo ezikhethekileyo uxinzelelo yesalathisi, ezo zilungiselelwe setting up eqhuba izixhobo zohlolo mandatory. Bona zigcinwa Rostekhnadzor.

Kodwa naliphi na ishishini kunye naluphi na uhlobo kwezi zixhobo yenzelwe ukulinganisa xi kuphela. Ngoku uyazi into igeyiji zeziphi na iintlobo ze baqonde malunga nomlinganiselo xi siseko.
