Turbine flow meter yog cov khoom siv txhim khu kev qha siv dav hauv roj, roj, kev kho dej, thiab kev lag luam tshuaj. Txawm li cas los xij, xaiv qhov tsim nyog yuav tsum xav txog ntau yam. Ntawm no peb sau tsib yam tseem ceeb los pab koj txiav txim siab zoo tshaj plaws rau koj daim ntawv thov.
1. Cov khoom ua kua dej thiab sib xyaw ua ke
Xav txog cov yam ntxwv ntawm cov kua dej- xws li viscosity, kub, siab, thiab corrosiveness. Turbine flow meter ua haujlwm zoo tshaj plaws nrog cov kua dej huv, qis -viscosity. Yog tias koj qhov nruab nrab muaj cov khib nyiab, npuas, lossis muaj tshuaj lom neeg, koj yuav tsum xaiv cov khoom thiab cov qauv uas tuaj yeem daws cov teeb meem no.
Tswv yim: Nco ntsoov xyuas cov khoom siv sib xws los tiv thaiv kev hnav, xeb, lossis kev nyeem tsis raug.
2. Flow Rate thiab Accuracy Requirement
txawvturbine metersua haujlwm zoo ntawm qhov sib txawv ntws. Xyuas kom tseeb tias qhov ntsuas qhov kev khiav hauj lwm sib haum nrog koj qhov system qhov tsawg kawg nkaus thiab qhov siab tshaj plaws ntws. Tsis tas li, xav txog koj qhov kev xav tau raug. Qhov raug raug ntawm peb cov kua turbine flowmeter yog 1% FS, thiab 0.5% tuaj yeem hloov kho.
Ceeb Toom: Ib qho kev tsis sib haum xeeb hauv kev khiav dej num tuaj yeem ua rau kev ntsuas yuam kev lossis kev saib xyuas ntxiv.
3. Kev teeb tsa ib puag ncig
Xav txog kev teeb tsa lub cev:
- Pipe orientation thiab loj
- Muaj ncaj yeeb nkab khiav
- Chaw rau tu
Turbine meters feem ntau xav tau cov yeeb nkab ncaj ntev ua ntej thiab tom qab lub sensor kom stabilize ntws, feem ntau yog 10D ntws thiab 5D downstream. Yog tias qhov chaw teeb tsa raug txwv lossis nkag mus tau yooj yim, xaiv lwm cov qauv compact lossis tsim nyog nrog tsawg ncaj nraim -khiav yuav tsum tau ua.
Tswv yim: Ib txwm nruab nrog cov dej ntws kom zoo kom ntseeg tau qhov tseeb.
4. Cov khoom tso tawm thiab kev sib xyaw ua ke
Feem ntau, turbine flow meter tuaj yeem tso tawm analog (4-20mA), digital (RS485), lossis kev sib txuas lus (Modbus, HART, thiab lwm yam). Xaiv raws li koj qhov system xav tau:
- Koj puas xav tau kev saib xyuas tej thaj chaw deb?
- Nws puas yuav txuas rau PLC lossis SCADA system?
- Puas yuav tsum tau sau ntaub ntawv?
Xaiv cov ntsuas nrog cov zis uas phim koj lub automation / tswj kev teeb tsa.
5. Nyiaj txiag thiab Ntev -Lub Sijhawm Txhawb Nqa
Tus nqi tsis yog tus nqi pem hauv ntej xwb. Nws suav nrog kev teeb tsa, kev saib xyuas, calibration, thiab kev pabcuam. Xav txog:
- Warranty thiab kev pab kho
- Muaj cov khoom seem
- Kev txhawb nqa thiab kev cob qhia
Peb muab kev sab laj kws tshaj lij thiab tom qab- muag kev txhawb nqa kom ntseeg tau tias koj cov peev txheej ua tau zoo dhau sijhawm.
Xaus
Xaiv lub turbine flow meter tsis yog hais txog tus nqi ntws xwb, nws yog hais txog kev ua raws li koj qhov kev ua haujlwm, ib puag ncig, thiab kev xav tau nyiaj txiag. Tsom ntsoov rau tsib qhov tseem ceeb no kom ntseeg tau tias muaj kev ntseeg siab, ntev - ua haujlwm tau ntev.
