Common Failures ntawm Cartridge rhaub thiab yuav ua li cas kom tsis txhob lawv

Cartridge rhaub tsis ua hauj lwm, xws li lub rhaub hluav taws xob, cua sov tsis sib xws, los yog hluav taws xob luv luv, tuaj yeem ua rau muaj kev poob qis hauv kev lag luam. Cov teeb meem no tsis yog tsuas yog pov tseg lub sijhawm tsim khoom, tab sis lawv kuj nce nqi kho thiab cov khoom pov tseg. Feem ntau ntawm lub sijhawm, qhov tsis ua haujlwm ntawm lub tshuab hluav taws xob cartridge tsis yog vim muaj teeb meem nrog cov khoom nws tus kheej, tab sis yuav ua li cas nws siv los yog xaiv. Paub txog dab tsi ua rau muaj teeb meem thiab yuav ua li cas zam lawv tuaj yeem pab tau ntau, tshwj xeeb tshaj yog nrog 440V tus qauv voltage cartridge rhaub, uas yog siv ntau heev.

Lub tshuab cua sov cartridge yog ib feem tseem ceeb ntawm ntau cov txheej txheem kev lag luam, xws li tuag casting, kev tsim khoom yas, kev ua zaub mov, thiab aerospace. Nws ua haujlwm los ntawm kev hloov hluav taws xob hluav taws xob mus rau hauv lub zog hluav taws xob los ntawm cov hlau tsis muaj zog, uas yog xa mus rau qhov uas nws txhais tau tias kom sov los ntawm cov hlau sheath. 440V tus qauv voltage cartridge rhaub yog nrov vim nws muaj ntau lub zog thiab ua haujlwm zoo, tab sis nws kuj tuaj yeem tawg yog tias siv tsis raug. Raws li kev paub dhau los, cov teeb meem feem ntau nrog cov khoom siv hluav taws xob yog cov hluav taws xob qhuav, hluav taws xob tsis sib haum, xeb, thiab kev teeb tsa tsis zoo.


Qhov teeb meem tshwm sim feem ntau nrog cov cua sov cartridge yog tias lawv qhuav hluav taws. Qhov no tshwm sim thaum lub rhaub yog qhib tab sis tsis yog tag nrho rau hauv cov khoom rhuab los yog tsis muaj cua sov hloov nruab nrab. Qhov no ua rau cov hlau tsis kam ua kom sov sai sai thiab rwb thaiv tsev kom tawg. Thaum qhuav firing 440V cartridge heaters, uas muaj hwj chim ntau dua, lub plhaub kub tuaj yeem nce siab tshaj 1200℃F, uas tuaj yeem ua rau cov coils hlawv tawm thiab txawm tias pib hluav taws. Txhawm rau zam qhov no, lub tshuab rhaub cartridge yuav tsum tau muab tso rau hauv lub pre-drilled qhov ua ntej qhib lub hwj chim. Koj tuaj yeem muab cov thermal muab tshuaj txhuam nruab nrab ntawm lub rhaub thiab lub qhov phab ntsa kom pab hloov cov cua sov ua haujlwm zoo dua.

Lwm qhov laj thawj rau qhov tsis ua haujlwm yog thaum qhov hluav taws xob tsis sib xws. Ntau lub chaw tsim khoom siv 440V cartridge tso cua sov hauv 220V fais fab mov tshuab los ntawm kev yuam kev. Qhov no ua rau cov cua sov tsis kub sai txaus thiab tsis tso cua sov txaus. Ntawm qhov tod tes, siv 220V cartridge rhaub hauv 440V tshuab yuav ua rau lawv kub dhau thiab hlawv tawm. Ua ntej txhim kho, nws yog ib qho tseem ceeb uas yuav tau xyuas lub hwj chim mov voltage thiab lub rhaub lub ntsuas hluav taws xob. Koj tseem tuaj yeem siv multimeter los kuaj xyuas qhov ua haujlwm kom paub tseeb tias lub rhaub dej ua haujlwm nrog lub hwj chim.

Corrosion yog ib qho kev txhawj xeeb nyob rau hauv cov chaw uas tib neeg ua haujlwm nrog tshuaj lom neeg lossis zaub mov. Cov dej noo, tshuaj lom neeg, thiab oxidation tuaj yeem ua rau lub plhaub ntawm lub tshuab cua sov, uas tuaj yeem ua rau lub qhov dej ntws thiab hluav taws xob luv. Thaum siv 440V cartridge rhaub nyob rau hauv cov chaw no, nws yog ib qho tseem ceeb uas yuav tau xaiv cov ntaub ntawv sheath uas tiv taus corrosion, zoo li 316 stainless hlau los yog Incoloy 800. Sealing lub terminals nrog silicone potting los yog IP67-rated leads kuj tuaj yeem khaws cov tshuaj thiab cov dej noo los ntawm kev nkag mus rau hauv lub rhaub.

Cartridge heaters tuaj yeem ua tsis tau yog tias lawv tsis tau teeb tsa kom raug, xws li yog tias lawv xoob dhau los yog nruj heev. Yog hais tias qhov haum yog xoob dhau lawm, cua sov yuav tsis hloov tusyees thiab yuav muaj chaw kub. Yog tias qhov haum nruj dhau lawm, cov ntaub qhwv tuaj yeem sib cais lossis cov rwb thaiv tsev sab hauv tuaj yeem puas. Rau cov cua kub cua sov, qhov kev pom zoo bore kam yog nruab nrab ntawm 0.001 thiab 0.003 nti. Txhawm rau txo qis tshaj - zawm, ntsia hlau- nyob rau hauv hom cua sov yuav tsum siv lub torque ciaj ntswj. Kev tshuaj xyuas qhov teeb meem ntawm kev teeb tsa thiab ntxuav lub qhov phab ntsa tsis tu ncua kom tshem tawm cov khib nyiab kuj tseem yuav pab tau lub rhaub kom ntev dua.

Hauv kev xaus, feem ntau cov teeb meem ntawm lub tshuab cua sov yuav zam tau los ntawm kev ua tib zoo saib seb koj siv thiab xaiv lawv li cas. Txhawm rau txo qis tus naj npawb ntawm qhov tsis ua tiav hauv 440V tus qauv hluav taws xob hluav taws xob lub tshuab hluav taws xob, nws yog ib qho tseem ceeb kom paub tseeb tias qhov hluav taws xob sib tw, txo qis hluav taws xob qhuav, xaiv cov khoom siv sheath, thiab ua raws li cov kauj ruam tsim nyog. Cartridge heaters muaj qhov xav tau sib txawv nyob ntawm qhov chaw ua haujlwm. Lub tswv yim tsim qauv tuaj yeem pab koj xaiv lub tshuab rhaub cua sov zoo tshaj plaws thiab cov txheej txheem kev teeb tsa, kom paub tseeb tias lub rhaub dej ua haujlwm zoo thiab tsis ua rau kev tsim khoom qeeb thaum nws tawg.
