Hauv kev ua haujlwm ib txwm muaj, ntau yam khoom siv feem ntau yog siv los pab qhov sib txawv ntawm qhov sib txawv hauv kev ua haujlwm zoo. Ib qho ntawm cov khoom siv tseem ceeb yog valve manifold. Lub hom phiaj ntawm nws daim ntawv thov yog los tiv thaiv lub sensor los ntawm ib sab ntawm kev puas tsuaj rau lub zog thiab cais lub transmitter los ntawm cov txheej txheem thaum tu, calibration los yog hloov. Ib tug raug 3-valve manifold suav nrog ib qho sib npaug ntawm qhov sib npaug thiab ob lub qhov thaiv qhov sib npaug ntawm qhov siab & qis sab ntawm lub tshuab xa tawm. Tag nrho cov li qub tau muab tso rau hauv ib qho hlau thaiv interfacing lub transmitter chamber los ntawm txoj kev sib txuas.
Tom qab kev teeb tsa tiav, pib ntsuas, qhib qhov sib npaug ntawm lub valve ua ntej, tom qab ntawd qhib qhov thaiv valve ntawm qis thiab siab siab sab hauv ib ntus. Tos kom txog thaum lub siab nyob rau hauv cov kab yog ruaj khov, kaw lub equalizing valve kom nruj thiab tawm hauv lub block li qub qhib, ces cov cuab yeej yog npaj txhij rau qhov sib txawv siab los yog txaus kom pom. Txhawm rau cais lub transmitter, kaw lub siab siab sab thaiv lub valve, qhib lub valve sib npaug thiab kaw qhov tsis tshua muaj siab sab thaiv lub valve kawg kom paub tseeb tias qhov seem seem nyob rau hauv lub transmitter chamber yog khaws cia kom tsawg li sai tau. Thaum kawg, qhib cov fittings los ntshav kom tshem tawm qhov seem siab tom qab qhov ntsuas raug txiav tawm ntawm cov txheej txheem.
Lwm hom rau DP transmitter yog 5-valve manifold, uas ua ke ob lub morel los ntshav li qub raws li 3-valve. Qhov ntxiv cov hlab ntsha hauv cov hlab ntsha tso cai rau qhov seem ntawm lub siab kom tso tawm mus rau qhov chaw nyob deb es tsis txhob nyob ze rau cov rooj plaub chamber.
Raws li tau hais los saum no, qhov nruab nrab qhov seem seem yuav tsum tau tso tawm ua ntej tshem tawm DP transmitter los ntawm kev pabcuam. Qee hom manifold tuaj yeem muab cov hlab ntshav rau txoj haujlwm tab sis ib txoj hauv kev ntau dua yog los ntshav fittings mounted ntawm transmitter chamber rooj plaub los ntawm xov txuas. Loosen thiab tshem tawm cov plugs, thiab qhov seem nruab nrab siab yuav tsum tau vented los ntawm lub orifices.
Thaum kawg, nws yog qhov pom tau tias DP transmitters feem ntau ntsia rau ntawm cov hlua. Pipe mounting bracket yog tsim los muab txoj hauv kev ruaj khov rau DP transmitters 'kev txuas ntawm qhov chaw ua haujlwm. Nws yog tsim los ntawm U-bolt thiab ncaj los yog L-shaped phaj.
Raws li kev paub txog cov cuab yeej tsim khoom lag luam muab cov khoom lag luam zoo tshaj plaws automation tov, WangYuan muaj peev xwm ua kom tiav cov khoom siv ntxiv ntawm peb.WP3051 series khoom. Yog tias koj muaj kev tsis ntseeg lossis xav tau ntawm cov khoom siv saum toj no thov tiv tauj peb.
