Plaub qhov tseem ceeb ntawm ib puag ncig xws li cov cua sov ambient siab, corrosive yas volatile fume, cyclic mechanical vibration thiab high humidity shorten the service cycle of hot runner dedicated thermocouples, and targeted material selection plus structural optimization can effectively mitigate such negative influences. Hauv qhov chaw txhaj tshuaj pwm qhov chaw, thermal hluav taws xob los ntawm kub khiav cua sov rings thiab manifolds nce ib puag ncig kub mus rau 80-180℃tsis tu ncua; PVC zoo tib yam-coated txuas xov hlau tawg thiab muaj hnub nyoog sai nyob rau hauv kev kub ntxhov, yog li fiberglass thiab Kapton coated cables yog tsim tshwj xeeb rau siab - qhov kub thiab txias nyob ib puag ncig, uas muaj peev xwm tiv taus ntev -lub sij hawm 300℃ambient kub yam tsis muaj rwb thaiv tsev tsis ua hauj lwm thiab dav sib txuam nrog high- kub kub engineering yas.
Cov kua qaub thiab alkaline corrosive vapor raug tso tawm thaum ua tiav PVC, nplaim hluav taws halogen- cov khoom siv hluav taws xob tsis zoo thiab cov khoom siv tsis zoo, uas nkag mus rau hauv cov khoob me me ntawm cov hlau tsis huv stainless hlau sheath, erodes internal magnesia rwb thaiv tsev muab tub lim thiab thermo-alloy tub ntxhais hlau, maj mam txo cov rwb thaiv tsev tiv thaiv luv luv thiab luv luv. Thermocouples siv nyob rau hauv xws li hnyav ua hauj lwm ib puag ncig txais electropolished seamless 316 stainless hlau sheath thiab tag nrho compacted magnesium oxide sau los thaiv corrosive gas infiltration; Teflon txheej thaiv txuas ntxiv ntxiv dag zog rau cov tshuaj tiv thaiv tiv thaiv cov kua qaub vapor puas tsuaj thiab dhau los ua cov khoom siv rau txhua hnub cov tshuaj ntim kub khiav pwm.
Cyclic vibration los ntawm nquag pwm clamping nkaus, reciprocating txav ntawm lub rooj vag valve koob thiab nruam khiav ntawm hydraulic twj tso kua mis. Ntev - lub sij hawm co loosens preloaded springs nyob rau hauv bayonet -style thermocouples thiab cais sensing probes los ntawm kub khiav ntsuas nto, ua rau tsis ruaj tsis khov kub tawm tswv yim thiab irregular cua sov hloov. High-kev tiv thaiv zoo- qaug zog alloy springs tom qab kev kho cua sov nruj yog teeb tsa ntawm kev co- cov kab ntau lawm, txo qis xoob-kev sib cuag tsis ua hauj lwm ntau dua 70% piv nrog cov pa roj carbon zoo tib yam; clip- ntawm cov thermocouples siv cov hlau tuab tuab kom tsis txhob txav deb ntawm lub tshuab cua sov sab nraud hauv qab kev co tsis tu ncua.
Damp thiab plua plav rhiav huab cua ua kom lub davhlau ya nyob twg oxidation ntawm thermocouple thaiv qhov xaus; Cov dej sib xyaw ua ke thiab cov plua plav yas ua cov txheej txheem oxide txheej ntawm cov khoom siv hluav taws xob thiab cuam tshuam cov teeb liab ruaj khov. Kev tswj xyuas qhov chaw txheem yuav tsum tau siv cov khoom siv tsis siv neeg kaw los ntawm siab - kub insulating roj hmab lub kaus mom thiab cov dej cawv tsis tu ncua thaum tu txhua hli kom tshem tawm cov oxide ntau ntxiv. Coastal molding factories raug kev txom nyem los ntawm ntsev pos huab customize nickel -plated davhlau ya nyob twg connectors los tiv thaiv ntsev corrosion. Thermocouple manufacturers qib cov khoom raws li kev ua haujlwm sib txawv: zoo tib yam PP / ABS molding nyob rau hauv ib puag ncig qhuav xaiv tus nqi -zoo 304 stainless hlau J- hom sensors; siab-kub corrosive engineering yas forming xaiv premium 316 ntxhia{10}}insulated K-hom thermocouples; customized tiv thaiv-corrosion nto kho yog ntxiv rau cov chaw ua haujlwm ntawm ntug dej hiav txwv. Kev sib raug zoo ntawm qib raws li qhov chaw tiag tiag hloov mus rau tus nqi tshaj plaws -txoj kev ua haujlwm tau zoo los txuas ntxiv cov kev pabcuam thermocouple.
