Makhalidwe a Magiya Oyendera Magiya

Ma gear flowmeter ndi mtundu wa positive displacement flowmeter womwe umayesa kuyenda kwa madzi powerengera kuchuluka kwa kuzungulira kwa magiya opangidwa molondola mkati mwa mita. Madzi omwe amadutsa mu mita amayendetsa magiya kuti azungulire, ndipo kuzungulira kulikonse kumafanana ndi kuchuluka kwa madzi komwe kumakhazikika, zomwe zimathandiza kuyeza kolondola kwambiri. Amagwiritsidwa ntchito kwambiri pazochitika zomwe zimafuna kuyeza molondola kwa zolumikizira zokhuthala, ndi makhalidwe ofunikira awa:

1. Kulondola kwambiri muyeso komanso kubwerezabwereza bwino kwambiri

Mfundo yoyezera imachokera pa kuyeza kokhazikika, kotero kulondola sikukhudzidwa kwambiri ndi kuchuluka kwa madzi, kuthamanga ndi kusintha kwa kukhuthala. Kulondola kwanthawi zonse kwa kuyeza kumatha kufika ±0.2% ~ ± 0.5% R, ndipo cholakwika chobwerezabwereza chili mkati mwa ±0.1%. Mbali imeneyi imapangitsa kuti ikhale yoyenera pazochitika zogulitsa monga mafuta oyeretsedwa, mafuta odzola, ndi kuyeza kwa mankhwala okwera mtengo kwambiri.

2. Kusinthasintha kwamphamvu kuzinthu zofalitsa zokhuthala kwambiri

Mosiyana ndi ma flowmeter a mtundu wa velocity (monga vortex, electromagnetic flowmeters) omwe kulondola kwawo kumachepa ndi kuwonjezeka kwa kukhuthala kwa madzi, ma gear flowmeters amagwira ntchito bwino poyesa ma high-viscosity media. Amatha kuyeza molondola madzi okhala ndi kukhuthala kuyambira 10 mpaka 1,000,000 mPa·s, monga mafuta olemera, resin, syrup, grease, ndi polymer solutions, ndipo ndi oyenera ma media okhala ndi zonyansa zochepa popanda kusokoneza kukhazikika kwa muyeso.

3. Kapangidwe kakang'ono komanso kukana kuthamanga kwambiri

Zigawo zamkati ndi zosavuta komanso zazing'ono, zopanda njira zovuta zotumizira. Thupi la mita nthawi zambiri limapangidwa ndi chitsulo chosapanga dzimbiri kapena chitsulo chopangidwa ndi njerwa, ndipo limatha kupirira kupsinjika kwakukulu kogwira ntchito (mpaka 6.4 MPa kapena kupitirira apo pamitundu yosinthidwa). Ndi yoyenera kuyiyika m'malo opapatiza komanso machitidwe a mapaipi opanikizika kwambiri, monga ma hydraulic oil circuits muzipangizo zamafakitale ndi mapaipi otumizira mafuta opanikizika kwambiri.

4. Chiŵerengero chachikulu cha turndown ndi magwiridwe antchito okhazikika pamitengo yotsika yamadzi

Chiŵerengero cha kutsika kwa madzi chikhoza kufika pa 1:10 ~ 1:50, chomwe chingathe kuyeza molondola momwe madzi amayendera komanso momwe madzi amayendera pang'onopang'ono. Makamaka pazochitika za kuchuluka kwa madzi komwe madzi ena amayendera pang'onopang'ono ndi ovuta kuyeza bwino, magetsi oyendera magetsi amathabe kusunga kulondola kwakukulu kwa muyeso, zomwe zimapangitsa kuti akhale oyenera kugawa molondola komanso kuyeza madzi pang'ono mosalekeza m'mafakitale a mankhwala, chakudya ndi mankhwala.

5. Kusakhudzidwa kwambiri ndi momwe mapaipi akumtunda ndi akumunsi amagwirira ntchito

Palibe lamulo lokhwima la magawo a mapaipi owongoka panthawi yoyika. Mosiyana ndi ma electromagnetic kapena vortex flowmeters omwe amafunikira magawo ataliatali owongoka a mapaipi kuti akhazikitse malo oyendera madzi, ma gear flowmeters amatha kuyikidwa pafupi ndi zigongono, ma valve ndi zina zowonjezera mapaipi, zomwe zimachepetsa kwambiri kuvutika kwa kuyika pamalopo ndikusunga malo okonzera mapaipi.

6. Zofunikira pa kukonza bwino kwambiri

Magiya opangidwa ndi makina olondola ndi ochepa kwambiri. Ngati madziwo ali ndi tinthu tating'onoting'ono kapena zosafunika, n'zosavuta kuyambitsa kuwonongeka kwa giya, kutsekeka kapena kuwonongeka. Chifukwa chake, ndikofunikira kukhazikitsa fyuluta yolondola kwambiri pamwamba pa mita. Kuphatikiza apo, kukonza nthawi zonse (monga kusintha zida zotsekera ndi mafuta odzola) kumafunika kuti magiyawo akhale olimba komanso osinthasintha, zomwe zimapangitsa kuti ndalama zogwirira ntchito komanso zosamalira zikhale zapamwamba kwambiri poyerekeza ndi ma flowmeter osakhudzana.
