Momwe Mungasankhire Flowmeter

Flowmeter ndi mtundu wa zida zoyesera zomwe zimagwiritsidwa ntchito kuyeza kuyenda kwamadzimadzi ndi gasi m'mafakitale ndi malo.Flowmeters wamba ndi electromagnetic flowmeter, misa flowmeter, turbine flowmeter, vortex flowmeter, orifice flowmeter, akupanga flowmeter.Kuthamanga kumatanthawuza liwiro lomwe madzi amadutsa papaipi, potuluka, kapena chidebe pa nthawi yoperekedwa.Oyang'anira ndi opanga zida amayezera mtengo uwu kuti ayang'anire ndikusintha liwiro ndi mphamvu zamachitidwe ndi zida za mafakitale.

Momwemo, zida zoyesera ziyenera "kukonzedwanso" nthawi ndi nthawi kuti zisawerengedwe molakwika.Komabe, chifukwa cha ukalamba wa zida zamagetsi ndi kusokonezeka kwa coefficient, m'malo ogulitsa mafakitale, flowmeter idzayesedwa nthawi zonse kuti iwonetsetse kulondola kwa kuyeza kwake, kuti athe kugwiritsidwa ntchito mosamala komanso panthawi yake.

Kodi Flowmeter Calibrate ndi chiyani?

Flowmeter calibration ndi njira yofanizira sikelo yokhazikitsidwa kale ya flowmeter ndi sikelo yoyezera ndikusintha muyeso wake kuti ugwirizane ndi muyezo.Calibration ndi gawo lofunikira la zida m'mafakitale osiyanasiyana omwe amafunikira miyeso yolondola kwambiri, monga mafuta ndi gasi, petrochemical, ndi kupanga.M'mafakitale ena monga madzi ndi zimbudzi, chakudya ndi zakumwa, migodi ndi zitsulo, kuyeza kolondola kumafunikanso kuwonetsetsa kuti kupanga bwino.

Mamita oyenda amawunikidwa pofanizira ndikusintha ma metering awo kuti akwaniritse milingo yodziwikiratu.Opanga ma Flowmeter nthawi zambiri amayesa zinthu zawo mkati akamaliza kupanga, kapena kuzitumiza kumalo odziyimira pawokha owongolera kuti asinthe.

Flowmeter Recalibration vs. Calibration

Flowmeter Calibration imaphatikizapo kufananiza mtengo woyezera wa flowmeter yothamanga ndi chipangizo choyezera choyezera chomwe chili pansi pamikhalidwe yomweyi, ndikusintha sikelo ya flowmeter kuti ikhale pafupi ndi muyezo.

Flowmeter Recalibration imaphatikizapo kuwongolera flowmeter yomwe ikugwiritsidwa ntchito kale.Kukonzanso kwanthawi ndi nthawi ndikofunikira chifukwa kuwerengera kwa mita yoyenda nthawi zambiri "kuchoka" pakapita nthawi chifukwa cha kusintha kwa zinthu zomwe zimachitika m'mafakitale.

Kusiyanitsa kwakukulu pakati pa njira ziwirizi ndikuti kuwongolera koyenda kumachitidwa isanatumizidwe flowmeter kuti igwiritsidwe ntchito, pomwe kukonzanso kumachitika pakatha nthawi yayitali.Zida zamapulogalamu zitha kugwiritsidwanso ntchito kutsimikizira kulondola kwa kuyeza kwake pambuyo poti flowmeter yasinthidwa.

Momwe Mungasankhire Flowmeter

Zina mwa njira zomwe zimagwiritsidwa ntchito kwambiri poyesa ma flow meter ndi:

• Kuyesa kwa Master Meter
• Gravimetric Calibration
• Piston Prover Calibration

Njira za Master Meter Calibration

Waukulu flowmeter ma calibration akuyerekeza mtengo anayeza wa flowmeter anayeza ndi kuyeza mtengo wa calibrated flowmeter kapena "waukulu" flowmeter ntchito pansi chofunika otaya muyezo, ndi kusintha masanjidwe ake moyenerera.Flowmeter yayikulu nthawi zambiri imakhala chipangizo chomwe kuwongolera kwake kumayikidwa kudziko kapena mayiko.

Kuti muyesere mita yayikulu:

• Lumikizani chida chachikulu muzotsatira ndi mita yothamanga yoyesedwa.
• Gwiritsani ntchito voliyumu yamadzimadzi yoyezera kuyerekeza kuwerengera kwa mita yayikulu yothamanga ndi mita yoyendera.
• Yang'anirani mita yoyenda poyesedwa kuti igwirizane ndi kuwongolera kwa mita yayikulu.

Ubwino:

• Easy ntchito, mosalekeza kuyezetsa.

Njira za Gravimetric Calibration

Kuyeza kulemera ndi njira imodzi yolondola kwambiri komanso yotsika mtengo komanso yowongolerera mita.Njira gravimetric ndi yabwino kwa ma calibration wa flowmeters madzi mu mafuta, madzi kuyeretsedwa ndi petrochemical mafakitale.

Kuti muyese kulemera:

• Ikani aliquot (gawo laling'ono) lamadzimadzi mu mita yoyesera ndikuyesani kwa nthawi yeniyeni pamene ikuyenda kwa masekondi 60.
• Gwiritsani ntchito sikelo yolinganizidwa kuti muyese kulemera kwa madzi oyesera.
• Nthawi yoyezetsa ikatha, tumizani madzi oyesera ku chidebe chokhetsa.
• Kuthamanga kwa aliquot kumapezeka mwa kugawa kulemera kwake kwa voliyumu ndi nthawi yoyesedwa.
• Yerekezerani kuchuluka kwa kuthamanga kowerengera ndi kuthamanga kwa mita yothamanga, ndipo pangani zosintha potengera kuchuluka komwe kumayesedwa.

Ubwino:

• Kulondola kwambiri (Mamita a master amagwiritsanso ntchito ma gravimetric calibration, kotero kulondola kwapamwamba kumakhala kochepa).

Njira za Piston Prover Calibration

Mu njira yosinthira mita ya piston calibrator, kuchuluka kwamadzimadzi kodziwika kumakanikizidwa kudzera mu mita yoyenda poyesedwa.Piston calibrator ndi chipangizo cha cylindrical chokhala ndi mainchesi odziwika mkati.

Pistoni calibrator ili ndi pistoni yomwe imatulutsa phokoso la voliyumu kupyolera mu kusamutsidwa kwabwino.The pisitoni calibration njira kwambiri abwino kwa mkulu-mwatsatanetsatane akupanga flowmeter calibration, mafuta flowmeter calibration ndi chopangira makina flowmeter calibration.

Kuti muyese piston calibrator:

• Ikani aliquot yamadzimadzi mu piston calibrator ndi mita yothamanga kuti muyesedwe.
• Kuchuluka kwamadzimadzi omwe amatulutsidwa mu pisitoni calibrator amapezedwa mwa kuchulukitsa kukula kwa mkati mwa pistoni ndi kutalika komwe pisitoni imayenda.
• Yerekezerani mtengo uwu ndi mtengo woyezera womwe umapezeka kuchokera ku mita yothamanga ndikusintha kusinthasintha kwa mita yothamanga moyenerera.
