Khoom Description
Peb lub tuam txhab muaj kev paub dhau los ua haujlwm ntau thiab peb cov txiaj ntsig tseem ceeb nyob hauv peb lub peev xwm los tsim thiab kho ntawm qhov me me. Raws li cov chaw tsim tshuaj paus kev cai, peb xyuas kom meej traceability labeling ntawm raw cov ntaub ntawv thiab ua tib zoo tshuaj xyuas cov khoom tiav.
Lub hom phiaj ntawm qhov qhib channel (Babbitt) flowmeter xa mus rau ntawm no yog ultrasonic qhib channel flowmeter. Nws siv cov cuab yeej qhib channel, raws li kev ntsuas tus nqi dej theem, ntsuas cov dej theem siab, ua ke nrog qhov loj me ntawm cov qauv weir groove, txoj kab nqes coefficient, channel raug, hydraulic txoj kab nqes, thiab ntws tus nqi ntsug dav hlau kho coefficient. , thiab tom qab ntawd tau txais tus nqi ntws los ntawm kev ua haujlwm hauv microprocessor ntawm lub ntsuas. Vim nws qhov ntsuas tsis sib cuag, qhib channel ntws ntsuas tuaj yeem siv rau hauv qhov chaw hnyav. Raws li kev tswj hwm ntawm microcomputer, qhib channel flowmeter emits thiab tau txais ultrasonic tsis. Raws li lub sij hawm kis tau tus mob, qhov kev ncua deb ntawm qhov qhib channel flowmeter thiab ntsuas cov kua theem yog xam kom tau cov kua theem siab.
Cov cuab yeej no yooj yim rau kev khiav lag luam thiab tuaj nrog ntau tus qauv weir suav nrog, ua kom yooj yim rau kev teeb tsa.
Tus tswv tsev txais yuav IP66 tiv thaiv qib (ua tib zoo saib xyuas kom nruj qhov qis hluav taws xob sib cuam tshuam thaum siv los tiv thaiv plua plav thiab ya raws), thiab peb qhov sensor txais IP67 qib kev tiv thaiv siab (thaum lub kaw lus kaw tag nrho txawm tias mus txog IP68)
Yog tias koj xav paub ntau ntxiv txog peb cov khoom, thov hu rau peb tam sim.
Txoj kev xa khoom yuav yog nyob ntawm hom kev thauj mus los uas koj xav tau, thiab qhov xwm txheej tshwj xeeb tseem nyob ntawm qhov ntau ntawm cov khoom koj tau xaj

Instrument Installation Method
Installation ntawm weir groove
Thaum siv cov cuab yeej no los ntsuas qhov ntws, yuav tsum muaj qhov ntsuas weir groove ntawm qhov qhib channel. Cov qauv thiab qhov ntev ntawm qhov ntsuas weir groove muaj nyob rau hauv Appendix 2 ntawm phau ntawv no. Koj tuaj yeem xa mus rau lwm cov ntaub ntawv qhia txog kev ntsuas dej hauv cov kav dej thiab cov kav dej, xws li National Metrological Verification Regulations for Open Channel Weir thiab Trough Flowmeters JJG711-90. Qhov kev pab cuam sab hauv ntawm qhov ntsuas muaj qhov preset hom kev xaiv rau feem ntau siv Basher slots, rectangular weirs, thiab triangular weirs. (Yog tias hom sib txuas tsis sib haum nrog cov cuab yeej no, thov qhia rau peb lub tuam txhab ntawm lub chaw tso dej ntawm cov dej theem kev sib raug zoo.)
Kev teeb tsa sensor
Lub installation txoj hauj lwm ntawm lub sensor ntawm lub channel yog nyob rau hauv raws li lub teb chaws metrological pov thawj kev cai "Qhib Channel Weir Flow Meter" JJG711-90. Daim duab peb sab weirs thiab rectangular weirs yuav tsum tau ntsia rau saum toj ntawm lub weir phaj, ntawm qhov deb sib npaug rau 3-4 lub sij hawm qhov siab tshaj plaws dej tob dhau los ntawm weir phaj; (Raws li pom nyob rau hauv daim duab 4 thiab 5) Basher zawj yog nyob ntawm 1/3 ntawm qhov inlet contraction seem. (Raws li pom hauv daim duab 6)
Lus Cim: Cov cuab yeej tau nruab rau hauv nruab nrab ntawm cov channel lossis ntawm qhov dej zoo li qub; Cov cuab yeej yuav tsum tau muab tso rau saum toj ntawm lub weir phaj lossis weir groove;
Nws raug nquahu kom siv fiberglass, PVC, lossis stainless hlau rau kev tsim cov weir slots thiab weir daim hlau. Qhov luaj li cas ntawm daim duab peb sab thiab lub voj voos weir qhib yuav tsum yog qhov tseeb, thiab sab hauv phab ntsa tig rau sab nkag yuav tsum du. Qhov loj ntawm Basher zawj caj pas yuav tsum yog qhov tseeb, thiab sab hauv phab ntsa ntawm qhov zawj yuav tsum du.
