Ukwahlukaniswa ingcindezi gauge: isimiso isinyathelo izinhlobo kanye izinhlobo. Indlela ukukhetha manometer umehluko

Ingcindezi kwabezindaba gaseous futhi uketshezi phakathi kwemigomo ezibaluleke kakhulu, nesilinganiso esidingeka nokugcinwa nezokuxhumana kanye processing izinhlelo. izinto Operable zihlanganisa izihlungi ahlukahlukene, piping izinhlelo, amadivayisi conditioning nokushaya komoya. Ukusebenzisa umehluko ingcindezi gauge, umsebenzisi akwembuli nje izimfanelo ingcindezi zamanje, kodwa futhi okwaziyo wasithatha umehluko phakathi ukusebenza ashukumisayo. Ukwazi lezi idatha kusiza ukuqapha kohlelo futhi kukhulisa nokwethenjelwa wokusebenza. Ngaphezu kwalokho, umehluko ingcindezi Izikali esetshenziselwa yokulinganisa ukugeleza uketshezi, igesi noma emoyeni onomfutho.

Umgomo we operation

Ngo kakhulu izincazelo Izikali ubuchwepheshe kanye nedatha ukubala esekelwe izinqubo ukusonteka amayunithi eqondile yokukala, njengemoto Izifutho. Lo msuka ukhonza inkomba izinzwa ingcindezi ukuhluka. Futhi iyunithi umehluko iba ukusebenza ingcindezi transducer - umsebenzisi uthola ulwazi ngesimo pointer we umcibisholo yomculo. Ngaphezu kwalokho, idatha kungenziwa okwethulwa Pascals, esehlanganise lonke sokulinganisa ububanzi. Le ndlela zokubonisa ulwazi, isibonelo, inikeza Testo umehluko manometer 510 ukuthi inqubo ukulinganiswa aqede isidingo uyibambe ngesandla sakhe, ngoba ezingemuva kudivayisi odonsa ekhethekile.

I imishini njengoba inkomba oyinhloko indawo umcibisholo ilawulwa uhlelo isigwedlo. isikhombi ukunyakaza kwenzeka kuze iyehla iyenyuka okwamanje ohlelweni ngeke ayeka ukuba nomthelela namandla athile. Isibonelo zakudala zalesi simiso sikhombisa umehluko manometer DM 3538M uchungechunge enikeza ezilinganiselwe ukuguqulwa delta (umehluko ingcindezi) futhi inikeza ngenxa opharetha kuwuphawu enobunye.

ngezigaba

Banikezwe yinkimbinkimbi inqubo ingcindezi nesilinganiso, izimfanelo abezindaba abasebenza kanye ukuguqulwa eyengeziwe, kukhona ezahlukeneyo eziningana ingcindezi umehluko ukusebenza kwayo ezimeni ezehlukeneyo. By the way, umehluko ingcindezi, okuyinto isimiso yokusebenza nomklamo walo buvezwa kudivayisi yakho igxile kungenzeka yokusebenzisa endaweni ethile - kungakho lokhu kwenziwa kanye ngezigaba. Ngakho, abakhiqizi babe izindlela ezilandelayo:

• Iqembu ketshezi umehluko ingcindezi Izikali, okubandakanya iflothi, insimbi, tube futhi indandatho ukulungiswa. Bona inqubo ukulinganiswa senzeka ngesisekelo ukusebenza uketshezi ikholomu.
• Digital umehluko ingcindezi Izikali. Kubhekwe ukusebenza kakhulu, ngoba ukunikeza ikhono ukukala hhayi kuphela izici iconsi ingcindezi, kodwa futhi ijubane onomfutho emoyeni kwemali, izinkomba umswakama futhi lokushisa. Ummeleli elivelele laleli qembu kuyinto umehluko ingcindezi gauge imagers kusukela Testo, okuyinto lisetshenziswa nasekuthandeni izinto sezimiso ukuqapha kwemvelo, emoyeni kanye nezifundo kwemvelo.
• Isigaba imishini. Lokhu Bellows kanye diaphragm okufushane ukuhlinzeka nesilinganiso by ukuqapha izici ingcindezi isici ebucayi.

imodeli Amabili ipayipi

Lezi zinsimbi zisetshenziselwa ukukala izinkomba ingcindezi futhi ekunqumeni therebetween umehluko. Le divayisi ne level ebonakalayo, okujwayeleke efomini ezimise U-. Ngu isakhiwo esinjalo umehluko ingcindezi gauge ukufakwa ngemibhobho emibili oxhumene mpo okuyinto awashintsheki esisekelweni lokhuni noma lwensimbi. Kuyinto ingxenye esiyisibopho idivayisi iphinde ungcwecwe ngengxube esikalini. Ekulungiseleleni tube nesilinganiso egcwele naphakathi ukusebenza.

Ngaphezu kwalokho, omunye amapayipi, ukusuthisa ingcindezi elinganisiwe. Ngasikhathi sinye, ipayipi yesibili baxhumana emkhathini. Phakathi nesilinganiso delta, kokubili kulinganiswa ingcindezi tube ihlolwe. A ezimbili-tube umehluko ingcindezi gauge nge ukugcwaliswa ewuketshezi ukuze ulinganise izinkomba cleaner, ingcindezi amagesi non-ezonakalisayo futhi emoyeni ezindaweni.

monotube imodeli

esetshenziswa ngokuvamile Monotube umehluko ingcindezi Izikali kuthiwa, uma kunesidingo ukuthola okusezingeni eliphezulu ukunemba yi. Ngo mishini, kusebenza esibuthakathaka, okuyinto ethatha ku ingcindezi nge Coefficient ngobukhulu. Kuphela tube eqondiswa ungcwecwe ngengxube isikali okubonisa idatha umehluko, futhi baxhumana imvelo ozungeze umhlaba wethu. Phakathi ingcindezi iconsi nesilinganiso ke baxhumana ingcindezi kulencane. naphakathi Ukusebenza is batheleka a umehluko ingcindezi gauge kuze kube seqophelweni kuze zero kufinyelelwe.

Zacindezelwa ingxenye ethile uketshezi agelezela tube kusukela isitsha. Njengoba umthamo uketshezi ukusebenza ukuthi usethathe tube sokulinganisa, uhambelana ivolumu kuhoxiswe umkhumbi, i-manometer olulodwa-tube uhlanganisa yalinganisa ukuphakama ikholomu ketshezi. Ngamanye amazwi, lo encishisiwe Iphutha nesilinganiso. Nokho, futhi lolu hlobo amadivayisi angekho khulula kusuka kahle.

Ngeziphambeko kusukela amagugu elilungile kungenzeka kubangelwa ukunwebeka ezishisayo of izingxenye kuleli thuluzi sokulinganisa, le ukusebenza kwabantu naphakathi nezinye amaphutha, Nokho, okuyinto, kukhona isici zonke izinhlobo ingcindezi ukushintshwa. Ngokwesibonelo, digital umehluko ingcindezi ngisho ne izilungiso imingcele density futhi lokushisa okuza futhi unephutha embundwini ezithile.

diaphragm umehluko ingcindezi gauge

I subtype main mechanical umehluko ingcindezi, okuyilona elisebenzayo futhi ihlukaniswe yaba amadivayisi nge metallic elementi wokulinganisa nonmetallic. Ngo amadivayisi nge flat diaphragm metal izibalo zisekelwe izici nenkanuko edlulele kuka e ingxenye wokulinganisa. Common futhi umehluko ingcindezi, lapho ulwelwesi uba ukwahlukanisa for emakamelweni ngokuhlukana. Ngesikhathi ukusonteka ukuthi bayavuma amandla Kumiswa isiphethu cylindrical Helical kukhishelwa nge element wokulinganisa. Njengoba kukhona Ukuqhathanisa ezimbili ezihlukene ingcindezi amagugu.

Futhi ezinye ukuguqulwa amadivayisi ulwelwesi ebekelwa eyodwa ukuvikelwa ukuchayeka - Lesi sici design ivumela ukuba lisetshenziswe ukulinganisa ukusebenza of overpressure. Naphezu electronics asebenzayo ukuqaliswa kwe umkhakha metrological iyonke, diaphragm Izikali bahlale okufunekayo ngisho nezisemqoka kwezinye izindawo. Ngokwesibonelo, zobuchwepheshe umehluko manometer DMC 01M uhlobo digital, naphezu Ergonomics futhi ukunemba okuphezulu, has imikhawulo ukusetshenziswa ngaphansi kwezimo lapho ulwelwesi kungenziwa amadivayisi eziqhutshwa.

Izifutho version

Ngo onobuhle esinjalo, isici ukumeda ibhokisi lukathayela kusuka metal, ephelele entwasahlobo Helical. indiza kudivayisi ihlukaniswe yaba izingxenye Izifutho ezimbili. Umthelela okukhulu kunakho konke ukucindezela ewela ikhamera ngaphandle kwe-Izifutho, kanye kencanikhulu - kule ingaphakathi kwangaphakathi. Ngenxa yalokho amabutho nezingcindezi ezahlukene inzwa zikhubazekile ngokuhambisana value wakhona sibalo oyifunayo. Lona Classic umehluko ingcindezi Izikali, okubonisa imiphumela izilinganiso nge umcibisholo ewashini. Kodwa kukhona namanye amalungu alo mndeni.

Okunye ukulandisa mechanical

annular Ngaphansi ezivamile, insimbi elintantayo futhi idivayisi umehluko ingcindezi wokulinganisa. Nakuba zikhona besshkalnye kuqhathaniswa olunembile futhi imodeli ukuqopha, kanye kumadivayisi nge contact amadivayisi kagesi. Ukwedlulisa ulwazi kubo futhi banikezela kude uxhumano kagesi noma pneumatics. Ukuze sithole ukusebenza kwezimali ngesisekelo eziguquguqukayo umehluko bakhiqiza imishini nge kufinyeta futhi zokuhlanganisa anezele.

Umehluko Digital ingcindezi Izikali

Amadivayisi yalolu hlobo ngaphandle imisebenzi eyisisekelo yokulinganisa umehluko ingcindezi kungacacisa ukuthi ezindaweni ukusebenza ashukumisayo. amathuluzi anjalo abizwa mshini DMC-01M. Digital umehluko ingcindezi gauge, ngokukhethekile, esetshenziswa ukulawula ukupholisa izinhlelo, izindawo zezimboni, ivumela ukubala kwemigomo gas ukusetshenziswa, ikhumbula izinguquko lokushisa, kanye ukugcina irekhodi izindleko isilinganiso izikhundla kulinganiswa. I-apharathasi unikezwa microprocessor olondoloza ngokuzenzakalela amarekhodi nesilinganiso kanye ekuqongeleleni ulwazi igesi flue. Yonke imininingwane wathola inqubekela phambili ziboniswa.

Izincomo ngokukhetha

Ukuthengiselana nokucindezela izinkomba adinga kudivayisi othembekile, izimo okuhambisanayo yokusebenza esiphezulu. Kule ndaba, kubalulekile ukunquma uhlu imisebenzi okumele yenziwe yidivayisi. Ngokwesibonelo, umehluko ingcindezi Testo 510 iyakwazi ukunikeza ukufundwa okunembile nge lokushisa isinxephezelo futhi unikeze idatha isibonisi digital. Kwezinye izimo, umfuziselo mkhosi, ngakho kufanele acabangele ukutholakala le ndlela.

Ukuze kusengaphambili esiphezulu idatha evumelekile kudingekile ukuqhathanisa izimfanelo idivayisi benethuba ezisebenza ethile yokusebenza imvelo. Akuwona wonke amadivayisi ingasetshenziswa i-oksijini, i-ammonia ne freon eziphindwe. Okungenani, angase ukunemba ongaphakeme.
