Muyeso chikoka ndi kutsimikizira za kunyamula akupanga flowmeter

The kunyamula akupanga flowmeter ndi mtundu wa akupanga flowmeter.Akupanga flowmeter ndi flowmeter kuti ntchito akupanga nthawi kusiyana ndi Doppler mumalowedwe, chifukwa otaya muyeso olondola a akupanga flowmeter pafupifupi popanda kutentha ndi mavuto otaya anayeza.Viscosity, kachulukidwe ndi magawo ena, ndipo amatha kupangidwa kukhala zida zoyezera zosalumikizana ndi zonyamula, kotero zimatha kuthana ndi zovuta zina zoyezera kuyeza kwamayendedwe monga zowononga zamphamvu, zosayendetsa, zotulutsa ma radio ndi zoyaka komanso zophulika.Mitundu ya zida.Magwiridwe ake osiyanitsidwa apindulira ogwiritsa ntchito.

1. Chikoka cha malo oyika, coupler ndi mzere wa chizindikiro pa muyeso

Kunyamula akupanga flowmeters makamaka ntchito Mipikisano pulse, burodibandi siginecha, ndi luso linalake kukana electromagnetic kusokonezedwa.Komabe, pali ma frequency apamwamba pamalo oyika, makamaka ngati gwero losokoneza ma frequency silikugwira ntchito mokwanira.Mzere wa chizindikiro cha transducer siwophweka kukhala wotalika kwambiri, ndipo chingwe cha coaxial cha impedance yeniyeni chiyenera kugwiritsidwa ntchito, ndipo sipayenera kukhala mgwirizano pamapeto ndi pakati.The akupanga lumikiza wothandizira ayenera kugwiritsidwa ntchito mmene ndingathere ndi wabwino phokoso madutsidwe osati zosavuta kusakaniza ndi mpweya viscous zinthu, monga madzi galasi, Vaselini, etc.

2, akupanga flowmeter si molondola calibrated

Aliyense flowmeter ayenera kutsimikiziridwa kapena calibrated pamaso ntchito, ndi kunyamula akupanga flowmeters n'kofunika kwambiri pa nthawi ino.Chifukwa kunyamula akupanga otaya mita zambiri okonzeka ndi angapo akanema transducers, oyenera osiyana chitoliro m'mimba mwake ranges, aliyense ya transducer ndi kuphatikiza khamu ndi theoretically ya otaya mamita.Choncho, ngati transducer yaing'ono ntchito calibrate kapena calibrate kunyamula akupanga flowmeter pa otaya muyezo chipangizo ndi yaing'ono chitoliro m'mimba mwake, ndiye ngati transducer lalikulu ntchito kuyeza otaya pa ntchito, ndi lofanana ndi ntchito unverified kapena calibrated flowmeter ndi kuyeza kolondola komwe sikungatsimikizidwe.Olondola njira zachokera wosuta ntchito monga buku, ndi kunyamula akupanga flowmeter ayenera kufufuzidwa kapena calibrated pa angapo mapaipi pa otaya muyezo zipangizo ndi m'mimba mwake kapena pafupi chitoliro ntchito.Pang'ono ndi pang'ono, m'pofunika kuonetsetsa kuti seti iliyonse ya masensa omwe amapangidwa ndi mita yothamanga ayenera kuyesedwa.Chitsimikizo cha mita kapena satifiketi yoyeserera ipereka chinthu chowongolera mita pamaseti angapo a masensa.Mukamagwiritsa ntchito nthawi yoyenda, onetsetsani kuti mwalowetsa chowongolera cha mita cholumikizira chofananira.

3, kunyamula akupanga flowmeter zofooka ndi zofooka

(1) The kunyamula akupanga flowmeter ya ulendo nthawi njira angagwiritsidwe ntchito kuyeretsa zakumwa ndi mpweya.

(2) Akupanga flowmeters ndi transducers kunja sangathe ntchito mapaipi ndi akalowa wandiweyani akalowa kapena makulitsidwe, kwanuko dented kapena anakweza mapaipi, ndi mapaipi ndi dzimbiri lalikulu makoma chitoliro.

(3) Panopa zoweta kupanga alipo akupanga flowmeters sangathe ntchito mapaipi ndi diameters zosakwana DN25mm.

(4) Chitukuko ndi kupanga zoweta akupanga flowmeters akadali akhanda, ndipo mtengo ndi mkulu.

Kuyenda muyeso ndi gawo lofunika kwambiri pakupanga mabizinesi, makamaka pankhani yosunga mphamvu ndi kuteteza madzi komanso chitetezo china chachilengedwe chagwiritsidwa ntchito kwambiri.Zam'manja akupanga flowmeter ndi mtundu watsopano wa flowmeter, zake mayiko ndi chuma zina flowmeters sangathe bini.Komabe, zolakwika zambiri zomwe zimapangidwa ndi zida zotere zimafunikira kuphunzira ndi kukambirana kopitilira.Mwachitsanzo, kusintha kwa malo amunda, ma frequency amphamvu, kukulitsa khoma lamkati la chitoliro, ndi thovu mu chitoliro kungayambitse kusintha kwina kwa mtengo wolakwika.Choncho, nthawi zonse mwachidule olondola muyeso njira mchitidwe, ndi yaitali ntchito bwino kunyamula akupanga flowmeters kuchita bwino udindo.

Zam'manja akupanga flowmeter ali ndi makhalidwe a kudya unsembe ndi kusintha ntchito, koma ayenera kudziwa njira yolondola pamene ntchito.Patapita zaka ntchito kumunda zinachitikira, anapeza kuti ntchito kunyamula akupanga flowmeters n'zosavuta kunyalanyazidwa, kusanthula zimene zimayambitsa mavuto ndi maganizo zothetsera.
