Isayensi nobuchwepheshe kuyashintsha usuku ngalunye. Izindawo zokukhiqiza zezimboni ezinembile kakhulu, izindawo zokukhiqiza imithi nokudla, kanye nezindawo zezokwelapha ezinzima zinezidingo eziphakeme kakhulu zokuhlanzeka komoya. Amakamelo ahlanzekile ekilasi 100, ikilasi 1,000, ikilasi 10,000, kanye nekilasi 100,000 abalulekile ekuqapheni ukugeleza komoya okuncane.
Ekuklanyweni, ekwakhiweni nasekusetshenzisweni kwamakamelo ahlanzekile, kubalulekile ukunciphisa ukuphazamiseka kwendawo ezungezile ekamelweni elihlanzekile, futhi ukulawula umehluko wokucindezela kuyindlela ebalulekile nephumelelayo yokugcina amazinga okuhlanzeka, ukunciphisa ukungcola kwangaphandle, nokuvimbela ukungcola okuphambene. Namuhla, ake sixoxe ngokusetshenziswa kwama-digital differential pressure gauges emakamelweni ahlanzekile.
Indlela yokuthola ingcindezi encane yomehluko
Ukulinganiswa komehluko wokucindezela okungaguquki kudinga ukuthi yonke iminyango endaweni ehlanzekile ivalwe.
Kufanele kwenziwe ngokulandelana kusukela ekuhlanzekeni okuphezulu kuya kokuphansi, kuze kufike emakamelweni anokufinyelela okuqondile ngaphandle. Umlomo wepayipi lokulinganisa utholakala noma kuphi egumbini ngaphandle kwethonya lokugeleza komoya, futhi ubuso bomlomo wepayipi lokulinganisa buhambisana nokujikeleza komoya. Idatha elinganisiwe nerekhodiwe kufanele ibe neqiniso ku-1.0Pa.
Izinyathelo zokuthola umehluko wokucindezela okuncane
Vala yonke iminyango kuqala.
Sebenzisa imitha yokuhlukanisa yedijithali ukukala umehluko wokucindezela phakathi kwamakamelo ahlanzekile, phakathi kwemigwaqo yegumbi ehlanzekile, naphakathi kwemigwaqo nezwe langaphandle. bese ubhala yonke idatha.
Izidingo ezijwayelekile zomehluko omncane wokucindezela
Idizayini noma izidingo zenqubo yegumbi elihlanzekile zinquma inani lokucindezela elihle noma elibi eligcinwe egumbini elihlanzekile elivivinywayo.
1. Umehluko wengcindezi engaguquki phakathi kwamakamelo ahlanzekile noma izindawo ezihlanzekile zamazinga ahlukene kanye namakamelo angahlanzekile (izindawo) akufanele abe ngaphansi kwama-5Pa.
2. Umehluko wengcindezi engaguquki phakathi kwegumbi elihlanzekile (indawo) kanye nendawo yangaphandle akufanele ube ngaphansi kwama-10Pa.
3. Emakamelweni ahlanzekile okugeleza aqonde ngqo, amazinga okuhlanzeka komoya aqinile kuneLevel 5 (Level 100), lapho umnyango uvulwa, ukugcwala kothuli endaweni yokusebenza yangaphakathi engu-0.6m ngaphakathi komnyango akufanele kube ngaphezu komkhawulo wokugcwala kothuli weleveli ehambisanayo. Uma izidingo zezindinganiso ezingenhla zingahlangatshezwanga, ivolumu yomoya omusha kanye nevolumu yomoya ophumayo kufanele kulungiswe kuze kube yilapho zifanelekile.

Kumaphi amakamelo ahlanzekile lapho kusetshenziswa khona ama-digital differential pressure gauge?
01. Igumbi lokuhlanza ifektri yemithi
Amageyiji okucindezela okuhlukanisayo edijithali angasiza ekuqapheni nasekulawuleni umehluko wokucindezela ngaphakathi kwegumbi elihlanzekile lefektri yemithi ukuqinisekisa ukuhlanzeka nokuphepha kwendawo yokukhiqiza, ngaleyo ndlela kuqinisekiswe ikhwalithi kanye nokuhambisana nokukhiqizwa kwemithi.
02. Iwadi elihlanzekile lesibhedlela
Isilinganiso sokucindezela sokwehluka kwedijithali singasebenzisa umehluko wokucindezela komoya ngaphakathi nangaphandle kwewadi ukuqinisekisa ukuthi ikhwalithi yomoya ihlangabezana nezindinganiso zezokwelapha nezempilo, ivimbele ukungcola kwangaphandle ukuthi kungangeni ewadini, futhi inikeze indawo ephephile nehlanzekile yeziguli nabasebenzi bezokwelapha.
03. Igumbi lokuhlanza i-workshop elenziwe ngogesi
Igeyiji yokucindezela yomehluko wedijithali ingasiza ekuqapheni nasekulawuleni amapharamitha abalulekile njengekhwalithi yomoya, umphumela wokuhlunga kanye nesivinini somoya egumbini elihlanzekile le-workshop kagesi, ngaleyo ndlela kugcinwe ukuhlanzeka nokulawulwa kwemvelo ekamelweni elihlanzekile le-workshop yokukhiqiza kanye nokuqinisekisa ikhwalithi nokuphepha kokukhiqiza kwemikhiqizo kagesi.
04. Igumbi lokuhlanza elihlolwayo
Igeyiji yokucindezela yomehluko wedijithali ingasetshenziswa ekuhlanzeni kokuhlola ukukala ingcindezi yomehluko egumbini elihlanzekile ngesikhathi sangempela nangokunembile, inikeze opharetha inkomba yokulungisa efanele ukuqinisekisa ukuthi umehluko wokucindezela omuhle nongemuhle ekamelweni elihlanzekile uhlala uhlangabezana nezidingo.
Yiziphi izindlela ezivamile zokulinganisa ingcindezi yedijithali ezisetshenziswayo
emakamelweni ahlanzekile?
