Hunhu hweMagear Flowmeters

Magear flowmeters rudzi rwe positive displacement flowmeter inoyera fluid flow nekuverenga huwandu hwekutenderera kwemagiya akagadzirwa nemazvo mukati memita. Mvura inopfuura nemumita inofambisa magiya kuti atenderere, uye kutenderera kwega kwega kunoenderana nehuwandu hwakatarwa hwemvura, zvichiita kuti kuyerwa kwakanyatsogadzirwa. Anoshandiswa zvakanyanya mumamiriro ezvinhu anoda kuyera kwakarurama kwe viscous media, ane hunhu hunotevera:

1. Kunyatsoyera kwakarurama uye kugona kudzokorora kwakanakisa

Nheyo yekuyera yakavakirwa pakuyera kwemvura yakagara yakamira, saka kururama hakukanganisi zvakanyanya nekuyerera kwemvura, kumanikidzwa uye kuchinja kwe viscosity. Kururama kwekuyera kwakajairika kunogona kusvika ±0.2% ~ ± 0.5% R, uye kukanganisa kwekudzokorora kuri mukati me ±0.1%. Ichi chinhu chinoita kuti ive yakakodzera kune zviitiko zvekutengeserana zvakaita semafuta akacheneswa, mafuta ekuzora, uye kuyerwa kwemakemikari ane mutengo wakakwira.

2. Kuchinjika kwakasimba kune midhiya ine viscosity yakakwira

Kusiyana nema "velocity-type velocity flowmeters" (semuenzaniso, "vortex", "electromagnetic flowmeters") ayo kururama kwawo kunoderera nekuwedzera kwe "fluid viscosity", ma "giya flowmeters" anoshanda zviri nani pakuyera "high-viscosity media". Anogona kuyera nemazvo ma "fluids" ane "viscosity" inotangira pa10 kusvika ku1,000,000 mPa·s, akadai semafuta anorema, resin, syrup, grease, uye polymer solutions, uye akakodzera kune "media" ine tsvina shoma pasina kukanganisa kugadzikana kwekuyera.

3. Chimiro chakamanikana uye kuramba kumanikidzwa kwakanyanya

Zvikamu zvemukati zviri nyore uye zvidiki, hazvina michina yakaoma yekutumira. Muviri wemita unowanzo gadzirwa nesimbi isingatsvedzeri kana simbi yakakandwa, uye unogona kutsungirira kumanikidzwa kwakanyanya kushanda (kusvika 6.4 MPa kana kupfuura kune mamodheru akagadzirwa). Yakakodzera kuiswa munzvimbo dzakamanikana uye masisitimu emapaipi ane kumanikidzwa kwakanyanya, senge ma hydraulic oil circuits mumidziyo yeindasitiri uye mapaipi ekutakura mafuta ane kumanikidzwa kwakanyanya.

4. Chiyero che turndown chakafara uye kushanda kwakagadzikana pamitengo yakaderera yekuyerera

Chiyero chekudzika kwemvura chinogona kusvika 1:10~1:50, izvo zvinogona kuyera nemazvo mamiriro ekuyerera kwemvura yakawanda uye ekuyerera kwemvura shoma. Kunyanya kune mamwe ma flowmeter akaoma kuyera zvakanaka, ma gear flowmeters anogona kuramba akanyatsojeka, zvichiita kuti akwanise kuenzaniswa nemazvo uye kuyera mvura shoma muindasitiri yemakemikari, chikafu nemishonga.

5. Kusanzwa zvakanaka kwemamiriro emapaipi ekumusoro neapasi

Hapana chinodiwa chakasimba chezvikamu zvemapaipi akatwasuka panguva yekuisa. Kusiyana nema electromagnetic kana vortex flowmeters anoda zvikamu zvemapaipi akatwasuka kwenguva refu kuti agadzirise nzvimbo yekuyerera kwemvura, magiya flowmeters anogona kuiswa pedyo nemagokora, mavharuvhu nezvimwe zvinhu zvepaipi, izvo zvinoderedza zvakanyanya kuoma kwekuisa panzvimbo uye kuchengetedza nzvimbo yekurongeka kwepaipi.

6. Zvinodiwa zvekugadzirisa zvakanyanya

Magiya akagadzirwa nemazvo madiki kwazvo. Kana mvura yacho iine zvidimbu zvakakura kana tsvina, zviri nyore kukonzera kupera, kuvharika kana kukuvara kwegiya. Saka, zvakakosha kuisa firita yakanyatsogadzirwa pamusoro pemita. Pamusoro pezvo, kugadziriswa nguva dzose (sekutsiva zvikamu zvekuvhara nemafuta ekuzora) kunodiwa kuti ive nechokwadi chekuti magiya acho anochinjika uye anochinjika, zvichikonzera mari yakawanda yekushanda nekuchengetedza kwenguva refu kana tichienzanisa nema flowmeters asingabatanidzi.
