Electronic multihead weighter troubleshooting method-repair method Rau kev kuaj pom qhov tsis raug, xws li: lub zog tsis zoo, kev puas tsuaj fuse, dhau xoob los yog nruj dhau qhov sib txawv, noo noo nyob rau hauv lub thawv sib txuas, cov khib nyiab ntawm lub cev thiab lub hauv paus, thiab kev puas tsuaj rau kev sib txuas. cable, sib koom tes solder pob qij txha thiab lwm yam kev ua txhaum tuaj yeem ua rau ntawm qhov chaw. Txoj kev daws teeb meem rau cov khoom siv hluav taws xob ntau lub taub hau - hloov Rau qhov tsis tuaj yeem hloov pauv xws li kev puas tsuaj, ntsuas kev puas tsuaj, kev sib txuas lub thawv puas, cable puas, thiab lwm yam, tsuas yog qhov zoo tuaj yeem hloov tau. Txoj kev daws teeb meem rau hluav taws xob multihead weighter-debugging Tag nrho cov faulty tsheb nplai yuav tsum tau calibrated thiab debugged tom qab lawv tau kho, tshwj xeeb tshaj yog tom qab cov khoom hloov.

Daim ntawv txuas: Kev Txiav Txim Siab Cov Kauj Ruam 1. Cov txheej txheem ntawm kev txiav txim seb qhov ntsuas qhov zoo lossis qhov tsis zoo: yog tias lub ntsuas ntsuas raug xav tias ua txhaum, cov txheej txheem hauv qab no tuaj yeem siv los txiav txim. Txoj Kev 1: Txuas lub 'meter' nrog lub simulator, thiab saib xyuas qhov kev hloov pauv ntawm qhov taw qhia tus nqi, xws li seb puas muaj drift, seb puas muaj cov zaub, thiab lwm yam. Yog tias qhov ntsuas tus nqi yog qhov ruaj khov, nws txhais tau hais tias lub ntsuas qhov zoo. Txoj Kev 2: Hloov nrog lub PCB seem, nkag mus rau qhov qub tsis zoo rau hauv PCB tshiab, thiab siv tib txoj kev los soj ntsuam qhov kev hloov pauv ntawm tus nqi qhia, thiaj li txiav txim siab seb qhov ntsuas puas ua yuam kev lossis tsis.

2. Txoj kev txiav txim seb lub sensor puas yog qhov zoo lossis qhov tsis zoo (1) Txoj kev txiav txim siab analog sensor (cov sensors hauv qab no yog sawv cev los ntawm LC) los ntsuas tus nqi tsis kam:±Ntawm EX (780)±Txog 5Ω,±Nruab nrab ntawm Si (700)±Txog 2Ω, tus nqi sensor kuj raug rau tus nqi nominal tsis kam ntawm lub sensor siv tau. Ntsuas voltage tus nqi:±Si feem ntau yog 0-25 mV, tom qab fais fab tuag, qhov ntsuas khoob yog feem ntau 0-5 mV. Ntsuas qhov ntsuas hluav taws xob ntawm lub ntsuas hluav taws xob: muab cov digital multimeter rau ntawm 20MΩ ntau, tso ib qho kawg ntawm lub ntsuas hluav taws xob rau ntawm lub plhaub lossis cov hlau thaiv, thiab lwm qhov kawg ntawm {±EXC,±Ntawm ib qho ntawm SI}, yog hais tias lub multimeter qhia 1, nws txhais tau hais tias cov rwb thaiv tsev tsis muaj qhov kawg, thiab lub sensor yog qhov zoo, txwv tsis pub nws yog qhov phem.

Saib xyuas seb lub sealing npog ntawm lub sensor ntog tawm. Xyuas seb cov xov hlau ntawm lub sensor puas tawg lossis tapping. Txheeb xyuas txhua lub ces kaum ntawm qhov ntsuas rau plaub-kab qhov yuam kev, yog tias muaj, nws tuaj yeem hloov kho, yog tias tseem muaj plaub-kaum yuam kev tom qab hloov kho, hloov lub sensor.

Tshem tawm cov sensors ntawm qhov ntsuas ib qho los ntawm ib qho, thiab saib xyuas qhov kev hloov pauv ntawm tus nqi qhia. Piv txwv li, yog hais tias tus thawj zaub drifts, tab sis tam sim no tus nqi qhia tau tias ruaj khov, nws txhais tau hais tias lub disconnected sensor puas. 3. Junction box tsis ua hauj lwm Ua ntej qhib lub hlws ris lub thawv saib seb nws puas ntub? Puas muaj av? Yog tias nws ntub los yog qias neeg, qhuav lub thawv sib txuas nrog lub tshuab plaub hau, thiab so lub thawv sib txuas kom huv si nrog cov paj rwb cawv.

Yog tias qhov teeb meem tsis tuaj yeem daws tau tom qab kev kho mob saum toj no, hloov lub thawv sib txuas. 4. Qhib lub hau npog ntawm lub ntsuas lub cev txhawm rau xyuas seb txhua qhov kev txwv LC puas muaj cov neeg tuag saum toj kawg nkaus? Kab rov tav txwv qhov sib txawv≤2mm, longitudinal txwv≤3mm ib. 5. Kev saib xyuas qhov system (1) Tom qab cov nplais hauv pem teb tau teeb tsa, cov ntawv qhia kev qhia, daim ntawv pov thawj ntawm kev ua raws, kev teeb duab kos duab thiab lwm yam ntaub ntawv yuav tsum tau khaws cia kom zoo, thiab nws tsuas yog muab tso rau hauv kev siv tom qab dhau qhov kev txheeb xyuas ntawm lub tuam tsev metrology hauv zos lossis ib lub chaw saib xyuas metrology pom zoo.

(2) Ua ntej lub tshuab hluav taws xob, nws yog ib qho tsim nyog yuav tsum tau xyuas seb lub tshuab hluav taws xob hauv av puas ntseeg tau; Tom qab tawm haujlwm thiab kaw, lub zog hluav taws xob yuav tsum raug txiav tawm. (3) Ua ntej siv lub ntsuas ntsuas, xyuas seb lub ntsuas lub cev puas hloov tau thiab seb qhov kev ua tau zoo ntawm txhua qhov kev txhawb nqa yog qhov zoo. (4) Lub ntsuas ntsuas qhov hnyav yuav tsum tau qhib thiab ua kom sov ua ntej, feem ntau yog li 30 feeb.

(5) Txhawm rau kom ntseeg tau qhov ntsuas qhov tseeb ntawm qhov system, yuav tsum muaj cov chaw tiv thaiv xob laim. Thaum vuam nyob ze, nws yog nruj me ntsis txwv tsis pub siv lub qhov hnyav platform raws li xoom kab hauv av los tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob. (6) Rau qhov sib npaug hauv av uas tau teeb tsa hauv thaj teb, cov khoom siv dej hauv lub hauv paus yuav tsum tau kuaj xyuas tsis tu ncua kom tsis txhob muaj qhov thaiv. (7) Khaws sab hauv ntawm lub thawv sib txuas kom qhuav. Thaum cov huab cua ntub dej thiab cov tee dej tso rau hauv lub thawv sib txuas, siv lub tshuab ziab plaub hau kom qhuav nws.

(8) Txhawm rau kom ntsuas qhov qub, nws yuav tsum tau ntsuas tsis tu ncua. (9) Thaum hoisting thiab ntsuas cov khoom hnyav, yuav tsum tsis muaj qhov tshwm sim; Thaum ntsuas lub tsheb-mounted cov khoom hnyav, qhov ntsuas qhov hnyav ntawm lub cev yuav tsum tsis pub tshaj. (10) Lub qag load ntawm lub tsheb tshuav nyiaj li cas muaj feem xyuam rau yam xws li lub peev xwm sensor thiab sensor fulcrum nrug.

General tsheb scale txwv tsis pub lub tsheb luv-wheelbase xws li forklifts ze rau qhov ntsuas los ntawm overscaled. (11) Cov neeg ua haujlwm nplai thiab cov neeg ua haujlwm tu cov cuab yeej yuav tsum paub txog cov lus qhia thiab cov ntaub ntawv tseem ceeb ua ntej lawv tuaj yeem ua haujlwm ntawm txoj haujlwm. 6. Kev tshuaj xyuas thiab kev daws teeb meem (1) Nrhiav qhov chaw txhaum: Yog tias lub tsheb loj tsis ua haujlwm, ua ntej nrhiav qhov chaw txhaum.

Txoj kev yooj yim yog kom paub nrog kev pab los ntawm emulator. Cov kauj ruam yog raws li nram no: Unplug lub teeb liab cable los ntawm lub junction box mus rau lub ntsuas, ntxig rau lub qhov (socket) ntawm lub simulator (9-core D-hom tiaj qhov (socket)) rau hauv lub interface J1 ntawm lub luj zaub maub los, tig lub hwj chim, thiab xyuas seb qhov ntsuas qhov ntsuas qhov hnyav puas ua haujlwm li qub. Nws txhais tau hais tias qhov txhaum nyob rau hauv qhov hnyav platform. Yog tias qhov ntsuas qhov ntsuas ntsuas tsis ua haujlwm ib txwm, qhov txhaum nyob hauv qhov ntsuas ntsuas. Kev tshem tawm ntawm nws qhov txhaum yuav tsum tau ua los ntawm cov neeg ua haujlwm tshuaj xyuas tshwj xeeb.

Cov saum toj no yog lub tshuab hluav taws xob multihead weighter teeb meem txoj kev qhia rau koj, Kuv vam tias nws tuaj yeem pab koj.
