Fault 3: Xeb sediment adheres rau titanium nto
Cov hauv paus ntsiab lus: Carbon steel brackets tsis muaj PTFE kev rho tawm tsim galvanic corrosion shedding hlau xeb.
Kev daws: Ntxiv tag nrho cov khoom ntawm PTFE gaskets thiab lub tes tsho cais ntawm titanium flanges thiab hlau txhawb; tsis tu ncua yaug xeb deposits ntawm lub raj nto thaum lub sij hawm tu.
3. Quartz Anti-Corrosion Heating Tube Common Faults
Fault 1: iav nto pos huab frosted txheej, nyuaj los ntxuav nplai
Lub hauv paus ua rau: Kub alkaline CIP kua reacts nrog silicon dioxide los tsim cov txheej txheej ntxhib etched.
Kev daws: Ncua tseg tag nrho cov alkali - muaj cov txheej txheem ntxuav, tsuas yog siv citric acid thiab cov tshuaj tua kab mob nruab nrab; hnyav frosted quartz raj yuav tsum tau hloov, tsis muaj txoj kev rov qab muaj.
Fault 2: Sudden tube rupture thaum cua sov los yog CIP kub hloov
Lub hauv paus ua rau: Tsawg thermal poob siab tsis kam; sau nrog microcracks tshwm sim los ntawm kev sib tsoo thiab extrusion thaum lub sij hawm installation thiab kev thauj mus los; Lub zog ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ua kom muaj qhov kub thiab txias sib txawv.
Kev daws: Tswj lub zog ceev hauv qab 0.8 W / cm²; txais yuav shockproof ua npuas ncauj ntim thiab roj hmab tsis pads thaum lub sij hawm installation; zam cov dej txias sai sai ntawm cov kav dej kub quartz; tsis tu ncua tshuaj xyuas microcracks pom nrog lub teeb kis tau zoo.
Fault 3: Cov iav me me sib xyaw rau hauv nruab nrab fermentation
Cov hauv paus hauv paus: Microcracks nthuav dav thiab tev tawm cov iav me me nyob rau hauv ntev -lub sij hawm thermal kev co vibration.
Kev daws: Hloov cov quartz tawg tam sim ntawd; quartz raug txwv tsis pub loj - nplai txuas ntxiv kom tsis muaj menyuam fermentation kab los tiv thaiv batch ua paug poob.
4. PFA Coated Heater Feem ntau ua txhaum
Fault 1: Txheej blistering, lub zos bulging thiab tev
Lub hauv paus ua rau: Ntev- lub sijhawm ua haujlwm kub siab tshaj 110℃; txias ceev-kub alternation nthuav qhov sib txawv ntawm fluoroplastic thiab steel substrate; corrosive nruab nrab invades sab hauv tom qab me ntsis khawb.
Kev daws: nruj me ntsis tswj qhov nruab nrab kub tsawg dua lossis sib npaug li 100 degree; txwv tsis pub quenching dej txias tam sim ntawd; qhwv nrog ntaub mos thaum lub sij hawm disassembly kom tsis txhob muaj khawb puas.

General Fault Handling Principles
- Paub qhov txawv ntawm cov khoom hauv paus ua ntej, tsis txhob siv cov kev tswj xyuas kev sib koom ua ke rau plaub lub raj cua sov. Stainless hlau tsom rau passivation thiab tiv thaiv -chloride pitting; titanium tshem tawm cov fluoride thiab npuas stagnation; quartz zam alkali thiab thermal shock; PFA tswj qhov kub thiab txias thiab tiv thaiv- kev tiv thaiv khawb.
- Ua ntej kev tiv thaiv kev hloov pauv ntawm cov txheej txheem tsis ua haujlwm (CIP qhov kub thiab txias, ntws nrawm, lub kaum sab xis, lub zog ntom ntom) kom txo tau qhov kev ua txhaum rov tshwm sim.
- Txiav txim kho me me tsis xws luag thiab irreparable tiav tsis ua hauj lwm nyias; tsis txhob yuam kev siv cov tubing cua sov puas ua rau kom sai li sai tau thiab batch seem poob.
