Yuav daws qhov txhaum ntawm hluav taws xob valve positioner li cas? Qhov zoo thiab qhov tsis zoo ntawm hluav taws xob valve thiab pneumatic valve Hluav taws xob valve positioner, tseem hu ua pneumatic valve positioner, yog cov khoom siv tseem ceeb ntawm tus tswj hwm, feem ntau yog siv nrog lub pneumatic regulator, nws lees txais cov teeb liab tawm ntawm tus tswj, thiab tom qab ntawd nrog nws cov teeb liab tso tawm. los tswj lub pneumatic regulator, thaum lub regulator txiav txim, qhov kev hloov ntawm lub valve qia thiab los ntawm cov neeg kho tshuab cov lus tawm tswv yim rau lub valve positioner, valve txoj hauj lwm los ntawm cov hluav taws xob teeb liab mus rau lub sab sauv system. Los ntawm ntau tshaj 20 xyoo dhau los ntawm kev sib sau ua ke, thiab cov kws tshaj lij kev lag luam thiab cov khoom siv hluav taws xob valve positioner rational analysis ua ke nrog ntau qhov kev kho qhov chaw, hluav taws xob valve positioner txhaum kev faib tawm, kev txheeb xyuas qhov ua rau qhov txhaum thiab nrhiav kev daws teeb meem, Kuv vam tias yuav muab cov cuab yeej ua haujlwm hauv kev teeb tsa thiab kev debugging ntawm tus actuator lossis kev saib xyuas txhua hnub ntawm hluav taws xob valve positioner los pab. 1. Huab cua qhov siab hloov pauv ntawm hluav taws xob valve positioner Saib xyuas lub tshuab lim cua siab reducer, hauv qab dej thiab av. 2, hluav taws xob valve positioner muaj lub teeb liab input tab sis cov zis yog me me los yog tsis Vim yog kev hloov kho ntau dhau ntawm kev mus ncig trimmer ntsia hlau ntawm lub positioner, lub kauj ntawm lub cev muaj zog yog unwelded, thiab cov hlau lead tuaj yeem welded. Torque lub cev muaj zog coil sab hauv hlau tawg lossis hlawv tawm vim overcurrent; Siv ib tug multimeter los ntsuas qhov coil kuj. Nquag, nws yuav tsum yog li 250. Yog tias qhov sib txawv ntawm 250 L loj dhau, hloov lub kauj. Kev tiv thaiv kab mob tsis zoo; Txheeb xyuas cov kab hluav taws xob terminals kom tshem tawm loosening. Lub teeb liab txuas txuas yog thim rov qab: Xyuas seb qhov (+) (-) lub davhlau ya nyob twg txuas yog thim rov qab. Nozzle baffle txoj hauj lwm tsis yog lawm: kho qhov sib npaug, saib cov zis hloov pauv. Loose nozzle kho cov ntsia hlau: zawm lub nozzle kho cov ntsia hlau kom ua tau raws li kev mus ncig. Lub amplifier yog faulty; Xyuas seb lub amplifier faulty los yog hloov nws. Pneumatic blockage: Siv 0.12 kom dhau cov av. Qhov chaw thaiv qhov chaw: lub rooj zaum hauv qab ntawm qhov chaw, muaj lub qhov cua nozzle, yog tias koj tsis xyuam xim rau qhov thaiv, qhov chaw yuav tsum tsis ua haujlwm. Baffle lever txuas caij nplooj ntoos hlav deformation los yog tawg; Qhib lub locator cover thiab hloov nws. Hloov tus ncej ntawm cov hlau nplaum ruaj khov thiab xyuas seb lub valve puas ua haujlwm. Cov lus qhia qib poob; Kho qhov sib npaug thiab saib seb lub valve ua haujlwm li cas. Cov lus taw qhia qib ntau ruaj tus pin skew: Kho tus pin kom ua tau raws li kev mus ncig. Lub regulating valve nrog tes log tsis raug ntaus rau hauv nruab nrab txoj hauj lwm; Txheeb xyuas qhov kev nyab xeeb ntawm tes tuav lub valve thiab kho nws mus rau qhov chaw nruab nrab. Loose CAM lossis txoj haujlwm tsis raug; Tighten CAM los yog hloov CAM txoj hauj lwm. Hydraulic tswj valve flapper lever lub caij nplooj ntoos hlav txhav tsis txaus: hloov (+) (-) polarity thaiv, kho qhov kev ncua deb ntawm lub flapper thiab nozzle, ua tau raws li qhov yuav tsum tau mus txawv tebchaws (tom qab ntawd yuav tsum tau hloov hom kev tswj hwm). 3, hluav taws xob valve positioner tso zis siab oscillation Av nyob rau hauv lub amplifier: av nyob rau hauv lub amplifier. Cov yeeb yaj kiab tso tawm lossis zaj duab xis taub hau: tshem tawm qhov tshwm sim, ua kom lub valve du ua haujlwm. Zaj duab xis taub hau diaphragm aging: hloov cov laus diaphragm tuaj yeem ua tau. Permanent magnet diverging yuam kev: kho qhov parallelism ntawm cov hlau nplaum ruaj khov kom tshem tawm cov hlau nplaum tsis ruaj khov. Loose ntswj kho cov lus tawm tswv yim: lim zawm kho cov ntsia hlau kom tshem tawm qhov kev vibration valve. Loj AC tivthaiv ntawm cov teeb liab tawm tswv yim: tshem tawm AC tivthaiv lossis sib npaug ntawm lub capacitor ntawm qhov kawg input. Lim tawm AC cuam tshuam. Rov qab siab cua txoj kev muaj av: tshem tawm cov av, kev daws teeb meem. Valve qws radial loosening: xyuas lub regulating valve. 4, hluav taws xob valve positioner tsis muaj input thiab output Backpressure thaiv: Thaiv av. Yog tias txoj haujlwm ntawm qhov tsis siv neeg thiab phau ntawv hloov pauv tsis raug, qhov tsis siv neeg thiab phau ntawv hloov pauv yuav tig mus rau txoj hauj lwm ntawm qhov tsis siv neeg kos valve. 5. Qhov tseeb ntawm qhov hluav taws xob valve positioner tsis zoo Nozzle, nres phaj hloov tsis zoo: kho qhov sib npaug lossis lub nozzle kho cov ntsia hlau, ua tau raws li qhov yuav tsum tau ua. Rooj vag valve rov qab siab cua to; Tshem tawm cov pa tawm. Lub radial hloov ntawm lub regulating valve yog loj: xyuas lub regulating valve. Kev kho tsis raug ntawm lub zeroed ntsia hlau: Kho lub zeroed ntsia hlau kom tau raws li qhov yuav tsum tau ua. Cov lus taw qhia qib thiab ruaj tus pin txoj hauj lwm tsis sib xws: Rov pib tus pin txoj hauj lwm raws li kev mus ncig. Qhov zoo thiab qhov tsis zoo ntawm lub pneumatic valve qhov kev ncua deb yog qhov loj dua li qhov hluav taws xob valve, lub pneumatic valve hloov qhov nrawm tuaj yeem hloov kho, cov qauv yooj yim, yooj yim los tswj, hauv cov txheej txheem ntawm kev txiav txim vim yog cov yam ntxwv tsis zoo ntawm cov roj nws tus kheej, tsis yog. yooj yim rau kev puas tsuaj los ntawm jamming, tab sis yuav tsum muaj cov huab cua qhov chaw, thiab nws cov kev tswj system yog complex tshaj li qhov hluav taws xob valve. Pneumatic valve teb yog ceev, nyab xeeb thiab txhim khu kev qha, ntau lub Hoobkas nrog kev tswj xyuas siab yog tsim los rau pneumatic twj tswj cov ntsiab lus teeb tsa compressed cua chaw nres tsheb. Electric txhais tau tias hluav taws xob.
