Yuav ua li cas yog lub txee rau dej yog zoo dua? Yuav ua li cas xaiv ib tug dej meter?

Dej - ib invaluable pab uas yog qhov tseem ceeb rau txhua tus nyob kab mob. Tab sis nws yog ib yam khoom uas peb yuav tsum tau them rau tus tswv tsev - lub xeev. Nyob rau hauv Russia, rau qhov metering dej noj meters ntsia. Ntxiv mus, rau txoj kev xaiv ntawm ntaus ntawv yog li tus tswv ntawm lub tsev. Qhov no muab sawv mus rau ib tug loj loj ntau yam ntawm cov khoom, nyob rau hauv kev twb kev txuas nrog cov uas peb txhua tus ib zaug nyob rau hauv kuv lub neej muaj yog ib lo lus nug: yog dab tsi zoo ntawm cov 'meter' rau dej yog zoo dua? To taub qhov no yuav pab kom peb cov tsab xov xwm no.

Yuav tsum tau los ntawm kev cai lij choj

Yav tas los cov neeg nyob rau lawv tus kheej xaiv yuav ua li cas them rau cov noj dej - raws li tus tsim cov kev cai ntawm kev cai lij choj los yog tsom rau kev nyeem ntawv dej meters. Tiam sis nrog lub nkag rau hauv cov hlab ntawm lub Federal Law hnub tim Kaum ib hlis 23, 2009 nyob rau hauv No. 261-FZ "Nyob rau lub zog txuag thiab lub zog efficiency kev txhim kho thiab nyob rau Amendments rau Tej Legislative Tubtxib Tes Haujlwm ntawm Lavxias teb sab Federation", lub installation ntawm dej meters tau ua ib tug yuav tsum txoj kev rau tag nrho cov pej xeem. Txoj cai tsis qhia kom meej zoo li cas ntawm cov ntaubntawv povthawj siv ntaus ntawv yuav tsum tau ntsia.

Nkaum no yuav tsum tsuas tswv tsev tau, uas yog officially lees paub tias raws li Dilapidated los yog qhov twg kev sib txuas lus yog hnav tawm thiab yuav tsum tau hloov. Nyob rau hauv tas li ntawd, nws tawm tag nrho ntawm tus tswv ntawm qhov, qhov twg qhov chaw ntawm lub txee txias dej (los yog kub kub) yog tsis tau vim yog lub tsim nta ntawm tus ciav dej. Nyob rau hauv cov ntaub ntawv no, qhov no fact yuav tsum ua pov thawj thiab daim ntawv nyob rau hauv vaj tse.

Cov ntaub ntawv thiab cov hom ntawm cov dej meters

Txee ntawm cov dej ntws yog txwv kom muab zais rau ob peb thaj av. Raws li cov lo lus uas peb, lawv muab faib ua muaj thiab domestic subspecies. Peb yuav tsis nyob rau hauv cov thawj ntau yam, tab sis ob hom kev ntaus ntawv yuav tsum tau ntau ncauj lus kom ntxaws saib xyuas.

Khoom vaj khoom tsev yuav tsum tau muab faib ua ob pawg:

1. "Ntub" recorder nyob rau hauv uas cov ntaubntawv povthawj siv ntaus ntawv yog ncaj qha kev cob cog rua nrog ib tug impeller los yog ib tug turbine tig los ntawm cov khiav ntawm cov dej.
2. "Qhuav" hydrometers, uas siv muaj ob tug cais seem rau dej noj ntsuas thiab cov ntaubntawv povthawj siv kiag li lawm.

Daws cov nqe lus nug "zoo li cas 'meter' rau dej zoo dua," peb yuav tsis quav ntsej tus ntaus ntawv cov ntaubntawv povthawj siv kiag li lawm. Nws, nyob rau hauv lem, yog nyob ntawm tus dais pab pawg neeg thiab nws muaj nws tus kheej yus tus yam ntxwv.

Neeg kho tshuab pab kiag li lawm los yog tachometer

Neeg kho tshuab recorder yuav muab teev cia rau sau ob txias thiab dej kub. Tus thawj xib fwb kev sib txawv ntawm pab kiag li lawm, nruj heev heev mus ua hauj lwm nyob rau hauv ib tug tej yam ntau yam kub, peb yuav saib tom qab. Tam sim no txoj kev tshawb no ntawm lawv cov qauv thiab hom kev lag luam.

Tachometer dej meters yuav muaj mus rau ib tug "qhuav" thiab "ntub" pab pawg neeg. Tus thawj sawv cev ntawm ib tug Valtec. Dej 'meter' sau ntawm lub hom hais los ntawm kev sib hloov ntawm lub turbine nyob rau hauv cov yeeb nkab. Lub sab saum toj ntawm lub impeller muaj ib tug magnet uas attracts ib tug hlau phaj sau npe yuav ua rau nws tig. Tej txaus meters muaj kev tiv thaiv los ntawm leaking thiab muaj siab durability.

Nyob rau hauv lub "ntub" khoom siv turbine yog rigidly kev cob cog rua rau ib tug tachometer. Nws Rotatable dej ntws Hnub Qub system hau dag zog yuam uas txiav txim txoj kev sib hloov kev ceev ntawm lub dial. Cov kev pab cuam ntawm cov dej meters yuav tsum muaj xws li ib tug yooj yim qauv, thiab cov shortcomings - ib tug yuav muaj clogging lub raj dej.

electromagnetic dej meters

Hais raws nraim li cas counter rau zoo dua cov dej - electromagnetic los yog txhua yam - tsis. Tag nrho cov nyob ntawm lub kev yam ntxwv ntawm lub watercourse thiab kav dej Circuit Court. Yog li, electromagnetic pab kiag li lawm, cov lwm yam, yuav tsum tau ib tug mus tas kev twb kev txuas mus rau lub mains, tab sis lawv, tsis zoo li lub tachometer li kis ntau yog readings.

Lub hauv paus ntsiab lus ntawm cov lag luam ntawm tej dej meters raws li nyob rau hauv electromagnetic induction txoj cai. Lub impeller rotates, ua ib electromagnetic teb, thiab lub siab tus nqi ndlwg (ntau dua tus nqi ndlwg) tus ceev rotating induction teb. Hais ntaus ntawv qhia nyob rau hauv LCD, ua rau nws yooj yim mus nyeem.

Txawv txee rau kub thiab dej txias

Lub hauv paus ntsiab lus ntawm cov lag luam Tallyman kub thiab dej txias yog tib yam. Ob hom pab kiag li lawm yuav tsum yog cov neeg kho tshuab los yog electromagnetic. Txawm li cas los, cov dej meter GBS (kub yeeb nkab) muaj ib co constructive nta:

1. Nws yog ua los ntawm tshav kub-resistant ntaub ntawv uas muaj ib tug tsis tshua muaj coefficient ntawm linear expansion. Qhov no tiv thaiv to thaum cua sov ntaus ntawv.
2. Nyob rau hauv nws tsim, nws muaj ib tug tshwj xeeb tam gasket, uas kuj tsis tso cai rau cov emergence of txia.

Tallyman dej txias cim nrog tsab ntawv "X", kub - "G". Rearrange lawv, i.e. UCR teem rau ib tug dej kub yeeb nkab thiab vice versa yog tsis pom zoo.

Yuav ua li cas lwm tus neeg xav txog thaum xaiv lub txee?

Xaiv ib tug counter rau zoo dua dej yuav tsis nco qab txog qhov inlet ntaus ntawv raws li txoj kab uas hla ntawm lub raj dej. Tsis noj mus rau hauv tus account qhov no tseeb, koj yuav yog tau siv nraum kev sib txuas, los yog tsis tau nruab lub tshuab muas.

Qhov thib ob qho tseem ceeb yog cov ntaub ntawv uas cov siv thiab ua. Qhov tseem ceeb tshaj ntawm cov neeg yog tooj liab thiab tooj dag. Kev siv ntawm lwm yam hlau thiab alloys yog tsis pom zoo vim hais tias lawv tso teeb meem tshuaj nyob rau hauv cov dej. Nws yog zoo dua yog hais tias tus counter muaj ib yam xim thiab tsis them nrog xim.

Tsis them sai sai mus ntau npaum li cas yuav tsum suav rau, yuav tsis muaj dej. Neeg kho tshuab pab kiag li lawm muaj ib tug txo nqi, raws li muab piv nrog electromagnetic tab sis lawv yog cov neeg yog npaum li cas qis. Nyob rau hauv lem, tus tachometer dej meters yog check ntau thiab yooj yim rau koj khiav lag luam. Cov kev them nqi ntawm cov ntaus ntawv yog nyob ntawm cov hom ntawm cov khw.

Manufacturers ntawm meters rau dej

Zoo seev rau lub domestic kev ua lag luam nkag los Valtec. Dej meter Italian ntau lawm raws kev ntseeg tau thiab durability, muaj yog ib tug neeg kho tshuab thiab electromagnetic. Feem ntau cov qauv muaj cov khoom mem tes ntaus ntawv rau tej thaj chaw deb kev nyeem ntawv.

Rau yav tom ntej pov thawj dej-meters Zenner ruaj, uas nws chaw ua hauj lwm yog nyob rau hauv ntau tshaj plaub caug lub teb chaws nyob ib ncig ntawm lub ntiaj teb no. Lwm yam nrov txawv teb chaws manufacturers yuav tsum tau muab sau tseg lub tuam txhab Viterra, Siemens, Wehrle.

Txee "Betar" peev xwm yuav txawv los ntawm cov seev ntawm domestic ntau lawm. Tsuas yog vim lawv cov nqi. Qhov nruab nrab nqi ntawm cov kev pab kiag li lawm yog nyob rau hauv ntau 500-1100 rubles, uas nyob rau hauv ua ke nrog nrog tau durability ua rau lawv muaj txiaj ntsim.

Ntawm cov lwm domestic producers yuav tau muab sau tseg lub tuam txhab "ntsuas" thiab lub tuam txhab "Mytishchi cua sov system." Qhov zoo tshaj ntawm lawv cov khoom, txhim khu kev qha thiab yog. Lawv nruj heev heev rau txawv diameters ntawm cov kav dej. Nyob rau hauv tas li ntawd, lawv cov khoom ua rau nws tau tsis them sai sai mus ntau npaum li cas dej meters. Qhov nruab nrab nqi rau cov ntaus ntawv yog nyob nruab nrab ntawm 500-900 rubles.
