Yuav Ua Li Cas Ntsuas Qhov Zoo ntawm Lub Tshuab Cua Sov Cartridge?

Cov neeg khiav dej num thiab cov kws kho mob feem ntau txhawj xeeb txog yuav ua li cas qhia thaum lub tshuab rhaub dej kub tawg. Ib qho hluav taws xob tawg tawg feem ntau tuaj yeem ua rau lub sijhawm poob qis, qhov sov tsis sib xws, lossis txawm tias muaj kev nyab xeeb. Nrhiav lub tshuab hluav taws xob tawg ua ntej nws dhau los ua qhov teeb meem loj yog qhov tseem ceeb ntawm kev tiv thaiv kev saib xyuas. Qhov kev qhia no qhia koj yuav ua li cas txhawm rau txheeb xyuas qhov zoo ntawm lub tshuab cua sov uas siv cov kev ntseeg tau, muaj tseeb.

Pib nrog kev kuaj pom


Feem ntau ntawm cov sij hawm, thawj qhov taw qhia ntawm teeb meem yog qhov tseeb. Ua tib zoo saib ntawm lub tshuab rhaub cartridge tuaj yeem pom cov teeb meem tam sim ntawd. Xyuas kom pom tseeb ntawm qhov deterioration, xws li cov kab nrib pleb sib sib zog nqus, khoov loj lossis deformations, los yog qhov tsis zoo ntawm corrosion thiab pitting. Yog tias koj pom cov cim kub hnyiab lossis tsis muaj xim ntawm qhov kawg ntawm lub davhlau ya nyob twg, nws tuaj yeem txhais tau tias lub cuab yeej kub dhau lossis muaj teeb meem hluav taws xob. Lub bulging los yog blistering sheath yog ib tug muaj zog kos npe rau ntawm sab hauv tsis ua hauj lwm nyob rau hauv ntau yam. Yog tias koj pom ib qho ntawm qhov tsis pom kev, nws feem ntau txhais tau hais tias lub tshuab hluav taws xob cartridge tau tawg thiab yuav tsum tau hloov kho kom cov khoom siv lossis cov khoom tsis zoo.

Qhov tseem ceeb Resistance Test

Qhov kev sim hluav taws xob yooj yim tshaj plaws rau lub tshuab hluav taws xob cartridge yog los xyuas nws qhov tsis kam. Txuas cov coj mus rau lub rhaub lub tshuab hluav taws xob nrog tus qauv digital multimeter teeb rau ohms (Ω) muaj nuj nqi. Xyuas kom tseeb tias lub rhaub yog tag nrho disconnected los ntawm ib lub hwj chim qhov twg los. Tus nqi tiv thaiv uas ntsuas tau muab rau koj tam sim ntawd cov ntaub ntawv hais txog yuav ua li cas lub zog sab hauv cov hlau tsis muaj zog. Feem ntau koj tuaj yeem txheeb xyuas qhov ntsuas kub ntawm qhov ntsuas kub los ntawm kev siv cov mis R=V² / P. Tus lej uas siab dua li qhov xav tau tuaj yeem txhais tau tias ib qho khoom tawg lossis tawg, thaum tus nqi qis dua tuaj yeem txhais tau tias muaj qhov luv luv hauv. Kev paub qhia tau hais tias txawm tias qhov kev hloov pauv ntau dua ± 10% los ntawm tus lej kwv yees tuaj yeem txhais tau tias qee yam tsis raug lossis tias nws tab tom yuav poob.

Kev ntsuas rwb thaiv tsev kom paub tseeb tias nws muaj kev nyab xeeb

Qhov hluav taws xob ntawm lub tshuab rhaub cartridge yuav tsum raug cais tawm ntawm cov hlau sheath kom nws ua haujlwm zoo. Qhov no yog qhov tseem ceeb heev rau kev ntsuas kev tiv thaiv insulating, feem ntau hu ua megger test. Ib tug tshwj xeeb rwb thaiv tsev tiv thaiv tester txuas ib tug coj mus rau lub rhaub lub sheath thiab lwm yam mus rau ib tug txiav. Koj muab qhov ntsuas hluav taws xob rau nws, feem ntau 500VDC lossis 1000VDC. Thaum txias thiab qhuav, lub tshuab cua sov zoo yuav tsum muaj kev nyeem ntawv tsis zoo ntawm qhov tsawg kawg yog 100 megaohms (MΩ). Qhov tseeb, kev nyeem ntawv qis dua 20 MΩ feem ntau txhais tau hais tias cov dej noo tau nkag los yog cov rwb thaiv tsev tau hnav, uas tuaj yeem ua rau muaj kev phom sij heev rau hluav taws xob poob siab. Kev ntsuas rwb thaiv tsev tsis tu ncua yog kev ntsuas kev nyab xeeb uas yuav tsum tau ua raws li, tshwj xeeb tshaj yog nyob rau hauv huab cua huab cua.

Kev ntsuas kev ua tau zoo los ntawm qhov kub thiab txias

Lub luag haujlwm tseem ceeb ntawm lub tshuab rhaub cartridge yog tsim kom muaj cua sov kom ntseeg tau. Kev kuaj xyuas kev ua haujlwm tseem ceeb yog ua kom lub qhov muag ntawm nws qhov ntsuas kub thaum nws tab tom khiav. Koj tuaj yeem ntsuas qhov kub thiab txias ntawm qhov chaw uas tsis yog -tus ntsuas kub infrared. Thaum lub rhaub tau qhib, nws yuav tsum muaj peev xwm ua tau thiab ua kom nws qhov kub thiab txias nyob rau hauv txoj kev nyab xeeb thiab khov kho. Yog tias qhov chaw txias dhau, nws tuaj yeem txhais tau tias seem tuag. Yog tias qhov chaw kub dhau, nws tuaj yeem txhais tau tias muaj qhov tsis ua haujlwm hauv cheeb tsam lossis kev sib cuag tsis zoo nrog lub bore. Thaum cov cua kub tsis sib npaug ntawm qhov ntev ntawm lub tshuab rhaub cartridge, nws feem ntau txhais tau hais tias qhov kev ntsuam xyuas hluav taws xob tau raug thiab lub rhaub yuav tsum tau hloov.

Cov lus qhia tseem ceeb rau kev ua haujlwm ntseeg tau

Cov kauj ruam yooj yim no ua hauj lwm ua ke los pab koj ntsuam xyuas lub tshuab cua sov. Pib los ntawm kev ua tib zoo saib kom muaj kev puas tsuaj rau lub cev. Tom ntej no, tshuaj xyuas qhov kev noj qab haus huv ntawm lub voj voog sab hauv los ntawm kev ntsuas qhov ntsuas qhov tseeb. Qhov tseem ceeb tshaj plaws, ua qhov kev ntsuam xyuas lub sijhawm ntawm kev tiv thaiv insulating kom paub tseeb tias nws muaj kev nyab xeeb siv. Thaum kawg, xyuas qhov ua tau zoo los ntawm kev saib seb qhov kub hloov pauv li cas thaum nws siv. Siv cov txheej txheem ntau- cov kauj ruam no muab tag nrho cov duab, uas pab tib neeg xaiv cov kev xaiv ntse txog kev tu thiab hloov. Qhov no txo ​​qis lub sijhawm tsis tsim nyog thiab ua kom cov txheej txheem cua sov ib txwm muaj kev nyab xeeb thiab zoo ib yam.
