Cov teeb meem tseem ceeb ntawm cov dej tshuaj rau cov ntaub fab thiab yuav ua li cas los txhawj xyuas lawv

Cov kev pov tseg ntawm qhov kev sib twj thiab qhov kev sib twj hauv cov dej tshuaj rau cov ntaub fab

Qhov dej tshuaj rau cov ntaub fab yog qhov ntau dua thiab qhov tsis zoo ntawm qhov hluav tais: cov laus thiab yuav ua li cas los txhawj xyuas

Cov teeb meem ntawm kev ntxhov siab hauv cov khoom tswj kev sib thaug (inverters) feeb tshaj plaws yog rau ob qhov tseem ceeb: tsis muaj kev txhawb nqa thiab kev sib thaug ntawm qhov ceev ntawm lub uas. Cov no cuam tshuam rau kev sov thiab ua rau cov capacitor (capacitors) tau sov thiab los ntawm qhov ceev, thiab cov ntaub tswv (solder joints) kuj tau sov thiab los ntawm qhov ceev. Thaum no dhau, qhov ntau ntawm kev kuaj ntxiv (ability to store charge) yuav nyob rau hauv 40% rau ntau yam, thiab kev tawg (electrical resistance) yuav nce siab. Qhov no ua rau qhov voltage yuav ncaj ncees thiab cuam tshuam rau cov kev tswj kev ntsuas qhov ntau ntawm cov ntaub (fabric tension control systems) hauv cov rooj tswj kev tsim. Cov dej tshuaj (Dust) kuj yog qhov teeb meem tseem ceeb ib yam, uas ua rau cov teeb meem ntau dua. Cov tsev tsim uas muaj ntau cov ntaub tshuaj hauv lub uas feeb tshaj plaws yuav muaj cov teeb meem ntawm cov khoom tswj kev sib thaug (motor drive failures) ntau dua 30% li compared rau cov tsev tsim uas muaj lub uas zoo dua. Los pab tshuam rau cov teeb meem no, kev tswj xyuas thaum ib txhis yog qhov tseem ceeb heev. Kev saib xyuas thiab tshuav cov khoom sov (heat sinks) thaum ib txhis yuav pab tshuam rau kev tsim thiab tswj xyuas zoo dua. Kev tswj xyuas qhov ceev ntawm lub uas kom tsis ntev dua 40 degrees Celsius kuj yog qhov tseem ceeb. Lawv ib qho tsev tsim kuj tau muab cov khoom tswj kev sib thaug (harmonic filters) mus rau hauv lub tsev tsim, uas pab tshuam rau kev ncaj ncees ntawm voltage. Cov lus piav qhia uas tau pub tshaj tsoom thaum lub lis piam tam sim no tau hais tias, kev pab tshuam rau kev txhawb nqa (airflow paths) xwb yuav pab tshuam rau cov teeb meem ntawm cov khoom tswj kev sib thaug (inverter failures) ntau dua 2/3, uas pab tshuam rau kev tswj xyuas kev muab kev ntsuas zoo (consistent power supply) uas tseem ceeb rau kev tsim cov khoom zoo.

Kev Taws Qhia PLC Tshuav: Cov Khaubnci Ntawm Qhov Chaw Tshuav, Cov Lus Qhia, thiab Cov Teeb Meem Ntawm Lub Xov Tooj I/O

Ntau yam teeb meem uas muaj rau PLCs tseem coob dua li cov ground loops uas ua rau muaj kev tsis zoo ntawm kev sib txuas, thiab ua rau kev sib txuas ntawm cov sensor thiab cov actuator tsis raug. Yog peb nyob rau hauv qhov chaw uas muaj ntau lub electromagnetic interference, qhov teeb meem yuav nyuaj dua yog tias cov khaub ncaws tsis muaj cov khawv tshuab (shielding) zoo, lossis tsis tau muab muab los ntawm qhov chaw uas muaj kev sib txuas (terminated) raws li kev xav tau. Qhov no ua rau muaj teeb meem ntawm kev sib sau (timing issues) uas kev haum (drying cycles) tsis haum rau kev npog ntawm cov roler. Lawv cov kev suav tshwj xeeb (studies) tau pom tias muaj txog 70% ntawm cov teeb meem ntawm kev sib sau (timing problems) yog los ntawm kev sib txuas khaub ncaws (cabling work) uas tsis zoo, tab sis cov leej twg (exact numbers) yuav cuam tshuam los ntawm qhov chaw uas muaj kev sib txuas (facility). Los ntawm kev tshuaj xyuas (fix things), muaj peb yam tswv yim tseem ceeb uas cov neeg siv yuav tsum ua thaum kawg. Muab tso cov kev tso cua (grounding systems) uas muaj kev tshuaj xyuas (resistance) ntev tsaus 0.1 ohms yog ib yam. Tshem cov khaub ncaws ncaj (ribbon cables) uas laus thiab muab tso cov khaub ncaws uas muaj ob kab (twisted pair versions) los pab tshem kev tsis zoo ntawm kev sib txuas (interference) zoo dua. Thiab tsis txhob lwm qhov kev suav xyuas kev tshuaj xyuas (signal delay checks) thaum muaj kev suav xyuas (routine maintenance periods). Cov chaw uas muab tso cov kev suav xyuas (monitoring) ntawm kev ntxiv (input) thiab kev tshem (output) thaum muaj kev suav xyuas (real time) tau pom tias muaj kev tshem tawm (cutting downtime) uas muaj kev sib sau (timing errors) los ntawm 50%, uas yog qhov tshwj xeeb heev thaum peb siv cov ntaub ntawv (materials) uas muaj kev tshuaj xyuas (sensitive) thiab xav tau kev sib sau (precise handling).
