Lub software feem ntau yog ua raws li lub xeev daim duab, uas ua raws li cov txheej txheem ua ntu zus ua ntej ua tiav ib txoj haujlwm txij thaum pib nres.
Peb Cov Kauj Ruam Kom Ua Tau Zoo Ua Tau Zoo Sab Nraud VFD
Sab nraum zoov VFD (VFD) tau dhau los ua ntau yam khoom pom nyob rau hauv chav kho tshuab. Los ntawm kev ntxiv ob peb kauj ruam yooj yim thiab muaj txiaj ntsig rau hauv koj qhov kev tiv thaiv kev saib xyuas koj tuaj yeem pab xyuas kom koj cov drives muab ntau xyoo ntawm kev pabcuam dawb.
Lub VFD tswj qhov ceev, lub zog, thiab kev taw qhia ntawm AC lub cev muaj zog los ntawm kev noj cov khoom siv hluav taws xob ruaj khov thiab zaus thiab hloov nws mus rau qhov sib txawv voltage thiab zaus tso zis. VFD's tswj circuitry tswj kev hloov pauv ntawm cov khoom siv hluav taws xob, feem ntau yog los ntawm pawg tswj hwm uas tswj kev tua hluav taws xob ntawm cov khoom siv hluav taws xob raws li qhov tsim nyog. Hauv cov ntsiab lus kuv nkag siab zoo dua, VFD yog lub hauv paus ntawm lub khoos phis tawj thiab lub zog hluav taws xob. Zoo ib yam li lub khoos phis tawj thiab lub zog hluav taws xob, tib yam kev nyab xeeb thiab cov khoom siv ceev faj siv rau VFD.
Feem ntau VFD poob rau hauv NEMA 1 qeb (sab vents rau cua txias) uas ua rau nws raug rau plua plav paug. Plua plav ntawm VFD tuaj yeem ua rau tsis muaj cua ntws ua rau kev ua haujlwm poob qis, ua haujlwm tsis zoo, lossis tsis ua haujlwm. Siv cov cua compressed los ntxuav yog qhov kev xaiv zoo; Txawm li cas los xij, koj yuav tsum xyuas kom cov huab cua tsis muaj roj thiab qhuav lossis koj yuav ua rau muaj kev phom sij ntau dua li qhov zoo.
VFD poob rau hauv NEMA 1 qeb yuav tsum tau muab tso rau hauv ib qho chaw huv thiab qhuav. Thaum lub sij hawm soj ntsuam xyuas, yog pom tias ya raws los yog condensation nyob rau hauv los yog ib ncig ntawm lub VFD koj yuav tsum tam sim ntawd xyuas rau ib puag ncig yam, uas tej zaum yuav ua rau muaj teeb meem. Yog tias cov dej tsis tu ncua, tej zaum koj yuav xav txog kev kho dua tshiab ntawm VFDs enclosure rau NEMA 12. Nws tsis siv dej ntau los corrode ib lub rooj tsavxwm; yog tias koj pom cov cim qhia ntawm corrosion thaum kuaj xyuas nws yog qhov zoo tshaj plaws los tham nrog cov chaw tsim khoom lossis cov chaw tsim khoom tus neeg sawv cev rau cov kauj ruam tom ntej.
Qhov no suab yooj yim; txawm li cas los xij, nws yog ib qho uas feem ntau tsis ua. Thaum tshav kub kub thiab kev vibrations hauv chav kho tshuab tuaj yeem ua rau xoob kev sib txuas. Kev sib txuas tsis zoo nws thiaj li ua rau arcing uas tuaj yeem ua rau muaj qhov tsis zoo ntawm qhov hluav taws xob, kev puas tsuaj rau cov khoom tiv thaiv, kev ua txhaum tam sim no, kev ua haujlwm tsis zoo, thiab kev puas tsuaj rau cov khoom siv hluav taws xob.
