Ukufakwa okulungile kwama-flowmeter ajwayelekile

Imitha yokugeleza iyinsimbi ekhombisa izinga lokugeleza elilinganisiwe kanye / noma inani eliphelele likaketshezi esikhathini esikhethiwe. Futhi iyinsimbi ebalulekile yokukala uketshezi nokugeleza kwegesi. Wonke umuntu kumele wabona izinhlobo eziningi ezahlukahlukene zamamitha wokugeleza. Indlela efanele yokufaka ibaluleke kakhulu ekugelezeni. Ake silandele le ndatshana ukuze sifunde ngamaphoyinti wokufaka ama-flowmeter amaningi asetshenziswa kakhulu.

Ⅰ. I-electromagnetic flowmeter

Umgomo wokulinganisa we-I-electromagnetic flowmeterAyinciki ezici zokugeleza. Uma kukhona ukugeleza okuthile okunesiyaluyalu kanye ne-vortex phakathi kwepayipi, akuhlangene lutho nesilinganiso.

Amaphuzu okufakwa:

1. Akufanele kube khona umthombo omkhulu wokudlidliza endaweni yokufakwa, futhi kufanele kuthathwe izinyathelo zokuqinisa ukuzinzisa ipayipi eduze nensimbi;

2. Akukwazi ukufakwa eduze kwemishini ekhiqiza izinkambu ezinkulu zikazibuthe ezifana nama-transformer amakhulu, ama-motors, amaphampu, njll., ukuze kugweme ukuphazanyiswa okuvela ezinkambeni ze-electromagnetic;

3. Lapho inzwa ixhunywe kwipayipi, kufanele iqinisekiswe ukuthi ipayipi ligcwele, futhi kungcono ukuyifaka phezulu;

4. Igobolondo lokudlulisa ligcwele futhi lixhunywe kunethiwekhi eseduze; ikhebula elivikelwe (uhlobo lokuhlukanisa) ixhunywe ngokwemiyalo, futhi ikhebula lesiginali (ohlelweni) lifakwe ekugcineni ohlelweni lokuvikela; Indandatho yesikebhe esifushane exhuma inzwa yokulinganisa nepayipi idinga ukufakwa, ukumelana okuyisisekelo kufanele kube ngaphansi kwama-ohms ayi-10 futhi akukwabiwa ngogesi;

5. Kufanele futhi kube nesigaba esithile esiqondile sepayipi enhla komfula we-flowmeter sensor, ngokuvamile u-5D ~ 10D.

Ⅱ. I-Ultrasonic flowmeter

I-ultrasonic flowmeter nayo iyi-flowmeter ejwayelekile. Ukufakwa kwayo kulula kakhulu futhi kulula ekufakweni kwawo wonke ama-flowmeter. Khetha nje iphoyinti elifanele lokulinganisa, ukufaka amapharamitha wepayipi endaweni yokulinganisa ku-flowmeter, bese ubeka iphenyo nje ulungise ipayipi.

Amaphuzu okufakwa:

1. Khetha isigaba sepayipi esigcwele uketshezi olufanayo futhi oluminyene futhi lula ukudlulisa amagagasi e-ultrasonic, njengesigaba samapayipi emile noma isigaba samapayipi evundlile.

2. Ibanga lokufakwa kufanele likhethwe njengesigaba samapayipi eqondile ngaphandle kwama-valve, izingqila, ububanzi obuguqukayo, njll. ngaphakathi kobubanzi bomfula obungaphezulu kokuphindwe izikhathi eziyi-10 ububanzi bepayipi oqondile kanye nophansi komfula omkhulu kunama-5 ububanzi bepayipi oqondile. Iphuzu lokufakwa kufanele likude ngokwanele kuma-valve, amaphampu, ugesi we-voltage kanye ne-Inverter neminye imithombo yokuphazamiseka.

3. Gwema ukufaka endaweni ephakeme kakhulu yohlelo lwepayipi noma amapayipi omile ngokuphuma kwamahhala.

4. Ngamapayipi avulekile noma agcwaliswe ngesigamu, i-flowmeter kufanele ifakwe esigabeni sepayipi elimise okwe-U.

Ⅲ. I-Vortex flowmeter

Izidingo eziyinhloko zokufaka ze-vortex flowmeter yizidingo zezigaba zamapayipi eziqondile nezidingo zokudlidliza kwamapayipi. Kufanele kube nezigaba ezinde zamapayipi eziqondile ezinhlangothini eziphezulu nasezansi komfula we-vortex flowmeter; ipayipi akumele libe nokudlidliza. Uma kukhona ukudlidliza, i-flowmeter idinga ukulungiswa. Ungeza ukulungiswa ezinhlangothini zombili.

Amaphuzu okufakwa:

Okwe-vortex flowmeter, lapho kulinganisa ukugeleza kwegesi, uma igesi elilinganisiwe liqukethe inani elincane loketshezi, ukugeleza kufanele kufakwe engxenyeni ephakeme yepayipi.

Lapho kulinganisa uketshezi, uma uketshezi olulinganisiwe luqukethe inani elincane legesi, ukugeleza kufanele kufakwe engxenyeni engezansi yepayipi.

1. Ukulinganisa umgodi wokulinganisa umgodi wokulinganisa ukushisa: Lapho ukulinganisa kwengcindezi kudingeka, imbobo yokulinganisa ingcindezi kufanele isethwe ku-2 ~ 7D ezansi komfula wokugeleza. Lapho ukulinganiswa kwezinga lokushisa kudingeka, setha inzwa yokushisa phakathi kuka-1 no-2D ezansi komfula wephuzu lokulinganisa kwengcindezi.

2. Ukwesekwa kwamapayipi: zama ukufaka i-flowmeter endaweni lapho ukusheshisa kokudlidliza kungaphansi kuka-20 m / s². Lapho ukudlidliza kwepayipi kuqine kakhulu, ukwesekwa kokuqiniswa kufanele kufakwe phakathi kwepayipi.

3. I-gasket: I-gasket akumele iphumelele ipayipi, ngaphandle kwalokho izodala amaphutha angamukeleki.
