Yuav Ua Li Cas Txiav Txim Thermocouple Compatibility Nrog Kev Sib Tw Kub Kub Sib Nqus Alloys

Kub khiav manifolds thiab nozzles yog tsim los ntawm H13, 420 stainless hlau, beryllium tooj liab thiab lwm yam alloys. Cov hlau sib txawv sib txuas nrog cov thermocouple sheath alloys ntawm qhov kub thiab txias yuav ua rau muaj peev xwm tiv taus qhov kub thiab txias, uas yuav ua rau kev ntsuas ntxiv offset yog tias ob cov ntaub ntawv hlau tsis sib haum. Ntau tus kws tshaj lij pwm tau saib xyuas qhov kev sib raug zoo ntawm cov hlau nplaum thaum xaiv cov thermocouples, uas ua rau qhov ntsuas kub ruaj khov uas tsis tuaj yeem ntsuas tau. Nplooj ntawv no qhia txog cov kev sib raug zoo sib xws ntawm cov txheej txheem kub khiav steel thiab cov ntaub ntawv thermocouple sheath.

Lub hauv paus ntawm tiam ntawm thermoelectric kev sib cuag muaj peev xwm

Kev hloov hluav taws xob dawb ntawm ob qhov sib txawv ntawm cov hlau alloys nyob ze ntawm qhov kub thiab txias tsim ib qho me me ntxiv thermoelectric voltage uas ntxiv rau millivolt teeb liab ntawm lub thermocouple nws tus kheej. Qhov no muaj peev xwm ntxiv tus nqi sib txawv nrog qhov kub thiab txias, yog li qhia txog qhov hloov pauv tsis raug. Qhov me me yog cov ntsiab lus ntawm cov thermocouple sheath thiab kub khiav substrate, qhov me me yog qhov kev sib cuag yuam kev.

Mainstream kub khiav pwm steel txuam rooj

1. H13 kub ua hauj lwm tuag steel (feem ntau raug manifold / nozzle khoom)
• Compatible sheaths: 316L stainless hlau, Inconel alloy; hu rau qhov muaj peev xwm offset Tsawg dua lossis sib npaug li 0.4℃hauv 200 ~ 420 degree, tsis tseem ceeb rau txhua qhov kev tsim khoom.
• Incompatibility Ntshiab tooj liab sheath, aluminium alloy sheath 1.2 ~ 2.0℃offset tshaj 350℃nruam drift nrog kub hloov.

2. 420 martensitic stainless hlau (corrosion-resistant nozzle rau PVC / halogen polymers)
• Qhov zoo tshaj plaws match: 316L electropolished stainless hlau sheath; offset ntawm kev sib cuag Tsawg dua los yog sib npaug rau 0.6℃.
• Lwm txoj kev: Inconel sheath, offset Tsawg dua los yog sib npaug rau 0.8 degree, haum rau high temp PPS molding.
• Tsis txhob siv 304 nyias- cov ntaub thaiv phab ntsa, rau qhov sib txawv ntawm qhov offset pom tau ntau dua 1℃vim qhov sib txawv ntawm chromium element.

3. Beryllium tooj liab nozzles (nyias- phab ntsa moulds nrog kub conductivity)
• Qhov zoo tshaj plaws match: tooj liab- alloy thermal conductive ribbon thermocouple; tiv tauj tej zaum nyob zero.
• Lwm txoj: Inconel sheath. Tswj nrog 0.7oC offset.
• Tsis txhob siv K-hom chromel-alumel liab qab alloy nyob rau hauv kev sib cuag nrog beryllium tooj liab. Loj drift saum 2℃ntawm qhov kub thiab txias.

Ntxiv cov txheej txheem optimization rau inevitable mismatching alloy sib cuag

1. Ib txheej ntawm thermally conductive npib tsib xee-raws li muab tshuaj ntxiv ntawm lub thermocouple sensing lub taub hau thiab kub khiav hlau nto; cov hmoov hlau hmoov muab tshuaj cais tawm ncaj qha kev sib cuag ntawm ob qhov sib txawv ntawm lub hauv paus alloys thiab txo cov khoom ntawm kev sib cuag.

2. Nws txais yuav ib qho ungrounded insulated armored thermocouple qauv, thiab cov magnesium oxide rwb thaiv tsev txheej nkaus cais cov alloy sheath los ntawm cov kub khiav hlau, yeej tsis txhob muaj kev cuam tshuam kev cuam tshuam, uas yog lub feem ntau dependable kev xaiv rau mixed alloy kub khiav pwm.

3. Nyob rau hauv thawj pwm calibration, sau cov nuj nqis taag offset nyob rau hauv sib txawv qhov chaw kub, thiab tsim cov segmented kub them nyiaj tsis nyob rau hauv lub maub los rau kev kho ntawm qhov tsis raug ntawm lub peev xwm sib txawv.

Compatibility xaiv xaiv rau pwm tsim theem

1. H13 tus qauv kub khiav: Standard K / N- hom thermocouples ua los ntawm 316L stainless hlau tuaj yeem sib tw dawb yam tsis muaj kev hloov kho ntxiv.

2. Kub khiav rau cov yas halogen - 420 stainless hlau corrosion resistant . 316L electropolished sheath thermocouples yog qhov zoo dua. Tsis txhob pheej yig 304 welded sheaths.

3. Beryllium tooj liab siab thermal conductivity nozzles rau nyias -phab ntsa kub ceev pwm: Siv insulated ungrounded sensors los yog tooj liab ribbon thermocouples kom tshem tawm cov alloy tiv tauj drift.

4. Mixed alloy composite kub runners (H13 manifold + beryllium tooj liab nozzle): Tag nrho cov ntsiab lus ntsuas yuav tsum tau nruab nrog ungrounded insulated thermocouples los koom ua ke qhov kev ntsuas precision yam tsis muaj segmentation hloov kho.333
