Hluav taws xob npauj npaim valve yog lub ntsiab tswj npauj npaim valve nyob rau hauv cov txheej txheem ntau lawm automation system, thiab nws yog ib qho tseem ceeb execution unit ntawm teb ntsuas.Yog tias hluav taws xob npauj npaim valve tawg hauv kev ua haujlwm, cov neeg ua haujlwm tu yuav tsum muaj peev xwm tshawb xyuas thiab txiav txim siab qhov ua tsis tiav, thiab tshem tawm kom raug, txhawm rau xyuas kom meej tias cov khoom yuav tsis cuam tshuam.
Cov hauv qab no yog peb qhov kev paub dhau los, suav nrog rau 6 hom hluav taws xob npauj npaim valve feem ntau ua txhaum thiab ua rau kev tsom xam, kev daws teeb meem, rau koj siv hauv kev saib xyuas haujlwm.
Ib qho ntawm qhov yuam kev phenomena:lub cev muaj zog tsis ua haujlwm.
Tej yam ua tau:
1. Cov kab hluav taws xob raug txiav;
2. Cov tswj Circuit Court yog faulty;
3. Txoj kev mus los lossis lub zog tswj lub cev tsis muaj zog.
Cov kev daws teeb meem sib xws:
1. Tshawb xyuas cov kab hluav taws xob;
2. Tshem tawm cov kab txhaum;
3. Tshem tawm qhov txhaum ntawm kev mus los lossis kev tswj lub zog.
Fault phenomenon 2:txoj kev sib hloov ntawm cov zis ncej tsis ua raws li qhov yuav tsum tau ua.
Kev soj ntsuam ua tau:cov theem ua ntu zus ntawm cov khoom siv fais fab yog thim rov qab.
Txoj kev tshem tawm sib xws:hloov ob txoj kab hluav taws xob.
Fault phenomenon 3:lub cev muaj zog overheating.
Tej yam ua tau:
1. Lub sijhawm ua haujlwm tsis tu ncua ntev dhau lawm;
2. Ib theem kab yog txiav.
Cov txheej txheem tshem tawm:
1. Tsis txhob khiav kom txias lub cev muaj zog;
2. Tshawb xyuas cov kab hluav taws xob.
Fault phenomenon 4:lub cev muaj zog nres.
Kev soj ntsuam ua tau:
1. Npauj npaim valve tsis ua hauj lwm;
2. hluav taws xob ntaus ntawv overload, torque tswj mechanism txiav txim.
Cov txheej txheem tshem tawm:
1. Tshawb xyuas lub npauj npaim valve;
2. Ua kom lub zog torque.
Fault phenomenon 5:lub cev muaj zog tsis nres khiav lossis lub teeb tsis teeb tom qab qhov hloov pauv nyob rau hauv qhov chaw.
Tej yam ua tau:
1. Lub tshuab stroke lossis lub zog tswj lub tshuab ua haujlwm tsis raug;
2. Cov txheej txheem tswj kev mob stroke tsis raug kho kom raug.
Cov txheej txheem tshem tawm:
1. Tshawb xyuas lub tshuab stroke lossis lub zog tswj lub zog;
2. Kho qhov kev tswj xyuas stroke.
Fault phenomenon 6:tsis muaj valve txoj hauj lwm teeb liab nyob deb.
Tej yam ua tau:
1. potentiometer iav teeb ntsia hlau xoob;
2. tej thaj chaw deb potentiometer tsis ua hauj lwm.
Kev daws teeb meem sib raug:
1. Tighten lub potentiometer iav teeb ntsia hlau;
2. Tshawb xyuas thiab hloov lub potentiometer.
Lub tshuab hluav taws xob npauj npaim valve yog tswj los ntawm cov khoom siv hluav taws xob, uas muaj kev nyab xeeb thiab txhim khu kev qha.Nws muaj ob qhov txwv, kev tiv thaiv overheat thiab kev tiv thaiv overload.Nws tuaj yeem yog centralized tswj, tswj chaw taws teeb thiab tswj ntawm qhov chaw.Muaj cov khoom siv hluav taws xob sib txawv, xws li hom ntse, hom tswj, hloov hom thiab ib hom, kom ua tau raws li qhov sib txawv ntawm kev tswj cov txheej txheem ntau lawm.
Lub built-in module ntawm hluav taws xob npauj npaim valve txais kev tshaj lij ib nti microcomputer thiab ntse tswj software, uas tuaj yeem ncaj qha tau txais 4-20mA DC tus qauv teeb liab los ntawm cov cuab yeej siv, thiab paub txog kev tswj xyuas ntse thiab kev tiv thaiv qhov chaw ntawm lub phaj qhib.
