Meta yemvura yerudzi rwakaoma (dry type water metre) zvinoreva mita yemvura yerudzi rwe rotor iyo yekuyeresa kwayo inofambiswa nezvinhu zvemagineti uye iyo counter isingabatane nemvura yakapimwa. Kuverenga kwakajeka, kuverenga kwemamita kuri nyore uye kuyerwa kwacho kwakaringana uye kunogara.
Nekuti iyo nzira yekuverenga yemamita yemvura yakaoma yakapatsanurwa kubva pamvura yakayerwa nebhokisi regiya kana ndiro yekuzviparadzanisa, haikanganisike nekusvibiswa kwakamiswa mumvura, kuitira kuti ive nechokwadi chekushanda kwakajairwa kwechiverengero chekuverenga uye kujeka kwe. kuverenga. Panguva imwecheteyo, hazvizokanganisa kuverenga kwemamita emvura nekuda kwemhute kana kudonhedzwa kwemvura pasi pegirazi kunokonzerwa nekusiyana kwekushisa pakati pemukati nekunze kwemamita, sezvakaita mumamita emvura yakanyorova.
Musiyano mukuru pakati pemamita emvura yakaoma uye mita yemvura yakanyorova ndiyo nzira yekuyera. Vane vhiri rakapatsanurwa kubva kune giya rezuva, uye kumucheto kwepamusoro kwevhiri kwevhiri kunosanganiswa nemagineti echigarire pamucheto wezasi wegiya rezuva. Kana kuyerera kwemvura kuchisundidzira vane vhiri kuti ritenderere, magineti ari kumucheto kwepamusoro kwegiya uye pazasi pegiya rezuva anokwezva kana kudzosera mumwe nemumwe kutyaira giya rezuva kuti ritenderere synchronously, uye mvura inoyerera nemumvura. mita inorekodhwa neiyo central transmission counter.
Sechiridzwa chekuyera huwandu hwehuwandu hwemvura inoyerera nepapombi yemvura yepombi, iyo yakaoma-mhando yemvura mita inogona kushandiswa muminda yeindasitiri, zvivakwa zvekutengesa uye zvivakwa zvekugara. Iyo iripo yakaoma-mhando yemvura mita inonyanya kutsamira pane iyo magineti yekubatanidza chimiro kufambisa kufamba. Sechinhu chakakosha cheiyo yakaoma-mhando yemamita emvura, inobata zvakananga kuita uye kushanda kweiyo yakaoma-mhando yemvura mita, ndiko kuti, inotaridza huwandu hwehuwandu hweiyo yakaoma-mhando yemvura mita uye hunhu hwemamita, iko kurongeka uye kugadzikana. yemamita emvura emhando yakaoma.
Iwo akasiyana magineti ekufambisa modhi yevane vhiri uye giya rezuva zvinokanganisa kutapurirana kuramba, nekudaro zvichikanganisa kunzwisiswa kwechiratidzo chemita yemvura. Iko kune kunyanya anotevera magineti ekutapurirana modhi: iyo magineti yakasanganiswa nzira yekufambisa yeaxial mutual kukwezva uye iyo magineti yekufambisa modhi yeradial repulsion. Iyo magineti yechigarire inoshandiswa mumamita emvura yakaoma inosanganisira Ferrite, Neodymium Iron Boron, uye dzimwe nguva.Samarium Cobaltmagineti. Chimiro chemvura mita maginetiinoshandiswa kazhinji inosanganisira magineti mhete, silinda magineti uye block magnet.
Kuenzaniswa nemamita emvura yakanyorova, iyo yakakosha magineti yakasanganiswa chimiro cheiyo yakaoma mvura mita haingovimbisi zvakanakira, asi zvakare inokonzera matambudziko anogona kuitika. Kuchenjerera kunofanira kubhadharwa kune kushandiswa!
1. Nemhaka yekuti kuwirirana pakati pe impeller shaft yemamita emvura uye counter center gear inotungamirirwa nemagnetic coupling, zvinodiwa zvekumanikidzika kwemvura uye hutano hwemvura zvakakwirira. Kana kudzvinyirirwa kwemvura kuchichinja zvakanyanya, iyo reverse phenomenon yemamita emvura inowanzoitika. Kana mhando yemvura yakanyanyisa kuderera, magineti eNeodymium pane impeller shaft anogona kunge akazara netsvina, zvichikonzera kutapurirana kwakashata.
2. Mushure mekushandisa kwenguva refu, iyo demagnetization yekubatanidza magineti inokonzera diki coupling torque uye hombe yekutanga kuyerera.
3. Kunyangwe mhete inorwisa magineti ichiwedzerwa pakubatanidza magineti ekutapurirana, kupindira kwakasimba kwemagineti kunogona kukanganisa maitiro ekuyera emuviri wemamita emvura.
