1. Kukhazikitsa Kosavuta Komanso Kogwira Mtima, Koyenera Zochitika Zochepa Malo

   Palibe kufunikira kukonza flange yovuta. Kukhazikitsako kungathe kumalizidwa pongolumikiza ndi kumangirira ku ulusi wosungidwa wa payipi, womwe ungayendetsedwe ndi munthu mmodzi, zomwe zingapulumutse kwambiri nthawi yomanga. Ndi yoyenera makamaka malo opapatiza, zida zomangidwira pakhoma, kapena zokonzanso mapaipi, ndipo imagwiritsidwa ntchito nthawi zambiri ndi makasitomala akunja m'mizere yaying'ono yopangira ndi zida za labotale.

2. Kugwira Ntchito Kwabwino Kwambiri Potseka, Kuchepetsa Zoopsa Zotuluka

   Ikagwiritsidwa ntchito ndi zinthu zotsekera monga tepi yotsekera ya ulusi wa PTFE ndi ma gasket, pamwamba pa cholumikizira cha ulusicho chimalumikizana bwino, zomwe zimatha kuletsa kutulutsa kwa madzi otulutsa mpweya (monga njira zothetsera asidi, zimbudzi). Poyerekeza ndi zolumikizira za flange, zolumikizira za ulusi zimapereka magwiridwe antchito okhazikika otsekera pansi pa mikhalidwe yotsika, ndipo zotsatira zake zotsekera sizimakhudzidwa mosavuta pakuchotsa ndi kukonzanso kukonza.

3. Kulondola Kwambiri kwa Ma Caliber Ang'onoang'ono, Kutaya Kochepa kwa Kupanikizika

   Ma electromagnetic flowmeter olumikizirana okhala ndi ulusi nthawi zambiri amapezeka m'ma calibers kuyambira DN10 mpaka DN50. Mu izi, sensa ili ndi kapangidwe kakang'ono, komwe kamatsimikizira kuti madzi akuyenda bwino panthawi yoyenda, zomwe zimachepetsa ma eddy currents ndi liwiro losafanana la kuyenda, motero zimapangitsa kuti muyeso ukhale wolondola. Pakadali pano, palibe ma protrusions ena (monga ma flange bolts) pakhoma lamkati la payipi, zomwe zimapangitsa kuti madzi azikana komanso kutayika kwa kuthamanga kwa magazi, zomwe zimapangitsa kuti ikhale yoyenera pazochitika zomwe zimafuna kulamulira kugwiritsa ntchito mphamvu.

4. Mtengo Wosasinthika, Kusinthana ndi Zogula Zazing'ono

   Thupi la valavu ndi zigawo zolumikizira za kulumikizana kwa ulusi zili ndi kapangidwe kosavuta, ndi ndalama zochepa zopangira kuposa kulumikizana kwa flange, zomwe zimapangitsa mtengo wa chinthucho kukhala wopikisana kwambiri. Kuphatikiza apo, kuchuluka kwa oda yocheperako (MOQ) ya ma flowmeter amagetsi ang'onoang'ono okhala ndi ulusi nthawi zambiri kumakhala kochepa, zomwe zimakwaniritsa zosowa za oda yoyesera ya makasitomala ang'onoang'ono akunja ndipo zimakhala chitsanzo chodziwika bwino chotsatsa malonda akunja pachiyambi.

II. Zoletsa Kugwiritsa Ntchito

1. Zoletsedwa ndi Caliber ndi Pressure, Osati pa Zochitika Zoyenda Kwambiri ndi Kupanikizika Kwambiri

   Chifukwa cha kufooka kwa mphamvu ya ulusi ndi magwiridwe antchito otsekereza, mulingo wapamwamba kwambiri wa ma electromagnetic flowmeters okhala ndi maulumikizidwe olumikizidwa nthawi zambiri supitirira DN50, ndipo kuthamanga kwa ntchito kumakhala mkati mwa PN1.6 - PN4.0MPa. Sizingakwaniritse zofunikira za mapaipi akuluakulu a mafakitale (monga, pamwamba pa DN100) ndi mapaipi amphamvu (monga, malo otulukira ma reactors amphamvu), kotero maulumikizidwe a flange kapena clamp-on amalimbikitsidwa m'malo mwake.

2. Kufunika Kwambiri kwa Kugwirizana kwa Mapaipi Panthawi Yokhazikitsa

   Ngati payipiyo ndi yosiyana kapena ngati chitsulo cholumikizira chasokonekera panthawi yomangirira screw, izi zingayambitse mphamvu yosagwirizana pa sensa, zomwe sizimangokhudza kulondola kwa muyeso komanso zingawononge chitsulo cholumikizira. Pakuyika, magawo okwanira a mapaipi owongoka a kumtunda (10D) ndi kumunsi (5D) ayenera kutsimikizika, ndipo sensayo iyenera kusungidwa kutali ndi magwero ogwedezeka monga mapampu ndi ma valve.

3. Kukonza ndi Kuchotsa Malo Kumachepetsedwa ndi Malo

   Ngati gawo lolumikizira ulusi lichita dzimbiri kapena kugwira ntchito kwa nthawi yayitali, zida zapadera zimafunika kuti zichotsedwe, zomwe zimakhala zovuta kugwiritsa ntchito m'mapaipi okhala ndi malo ochepa. Poyerekeza ndi kuchotsera kwa bolt kwa maulumikizidwe a flange, maulumikizidwe a ulusi amakhala ndi kusinthasintha kochepa pakusamalira, makamaka m'ma media omwe ali ndi kuwonongeka kwamphamvu, komwe ulusi umafunika kuwunikidwa nthawi zonse.

III. Mfundo Zofunikira Zowonjezera pa Kusintha kwa Malonda Akunja

1. Kusintha Zinthu Zofunika Kuti Zigwirizane ndi Mikhalidwe Yogwirira Ntchito Padziko Lonse

   Zipangizo za mawonekedwe a ulusi zitha kusinthidwa malinga ndi miyezo yapakati komanso yachigawo ya kasitomala. Zipangizo zodziwika bwino zosagwirizana ndi dzimbiri monga chitsulo chosapanga dzimbiri cha 316L ndi Hastelloy zimagwiritsidwa ntchito kuti zikwaniritse zofunikira za makasitomala aku Europe ndi America m'makampani opanga mankhwala ndi chakudya. Pazochitika zokhala ndi madzi abwino kwambiri, mawonekedwe a ulusi wa kaboni amathanso kuperekedwa kuti azilamulira ndalama.

2. Kutsatira Miyezo Yapadziko Lonse Yokhudza Ulusi

   Miyezo ya ulusi imasiyana m'madera osiyanasiyana akunja, kotero ndikofunikira kutsimikizira zosowa za makasitomala pasadakhale: Makasitomala aku Europe nthawi zambiri amagwiritsa ntchito BSPP (British Standard Pipe Parallel), pomwe makasitomala aku North America amakonda NPT (National Pipe Taper). Miyezo yoyenera iyenera kulembedwa bwino m'buku la malangizo kuti apewe mavuto okhudzana ndi kuyika.
