Kev npaj ua ntej kev teeb tsa
Ntxuav qhov chaw yuav tsum tau ntsuas: Siv cov lint -dawb daim ntaub dampened nrog industrial cawv los yog acetone kom huv si tshem tawm cov roj, xeb, oxide txheej, thiab plua plav tawm ntawm qhov chaw ntawm cov khoom raug ntsuas. Xyuas kom qhov chaw sib cuag yog tiaj tus thiab tsis muaj impurities, nrog ib tug roughness tsawg dua los yog sib npaug rau 0.1 hli;
Txheeb xyuas qhov xwm txheej ntawm kev sojntsuam: Paub meej tias cov thermocouple tiv thaiv raj tsis deformed, lub caij nplooj ntoos hlav tsis muaj xeb lossis yas deformation, cov hlau rwb thaiv tsev txheej tsis tawg, thiab lub thawv sib txuas yog kaw kom zoo;
Paub meej tias qhov chaw teeb tsa: Xaiv thaj chaw tiaj tiaj tsis muaj kev cuam tshuam kev vibration. Zam kev txhim kho ntawm cov welds, txhawb cov tav, los yog nkhaus qhov chaw nrog lub vojvoog ntawm curvature tsawg dua R50mm, txwv tsis pub nws yuav ua rau tsis sib xws thiab ntsuas qhov kub thiab txias;
Kev npaj cov cuab yeej: Npaj lub torque wrench (ntau txog 0–20 N·m), tu daim ntaub, tus pas ntsuas kub (rau tom qab- kuaj xyuas), thiab cov hnab looj tes tiv thaiv zoo li qub.
Installation txheej txheem
1.Txoj haujlwm thiab txhim kho lub hauv paus: Teem lub mounting ntsia liaj qhov rooj (M12 × 1.5 lossis M16 × 2) ntawm lub caij nplooj ntoos hlav-loaded thermocouple nrog rau ua ntej- teeb tsa lub qhov rau ntawm cov khoom siv casing, kom ntseeg tau tias cov xov yog perpendicular rau saum npoo raug ntsuas;
2.Initial tightening: Manually ntsia hlau rau hauv lub ntsia liaj qhov rooj kom txog rau thaum cov threads tag nrho koom. Tsis txhob siv cov cuab yeej los yuam cov ntsia liaj qhov rooj, tiv thaiv xov stripping;
3.Apply pre-tightening force: Use a torque wrench to tighten evenly with a torque of 10–15 N·m until a slight "click" sound is heard (indicating the torque is reached). Strictly prohibit over-tightening** (>20 N·m) tiv thaiv lub caij nplooj ntoos hlav overload tsis ua haujlwm;
4.Confirm tiv tauj raws li txoj cai: maj mam thawb lub sojntsuam; yuav tsum tsis muaj qhov cuam tshuam loj, thiab qhov ntsuas qhov kawg yuav tsum muaj kev sib cuag nrog lub ntsej muag, tsis tas nqa lossis raug tshem tawm;
5.Txuas cov teeb liab xov hlau: Txuas lub siab - cov kab hluav taws xob tiv taus kub rau hauv lub thawv sib txuas, kom ntseeg tau tias cov terminals raug kaw kom ruaj ntseg kom tsis txhob muaj kev sib txuas; siv cov hlua khi kom ruaj ntseg ntawm cov xaim routing kom tsis txhob rub lossis entanglement.
Installation Verification thiab Debugging
Fais fab- ntawm kev txheeb xyuas: Txuas cov cuab yeej tso saib, sau cov ntawv nyeem thawj zaug, thiab muab piv rau qhov paub qhov kub thiab txias (xws li lub ntsuas kub infrared). Qhov yuam kev yuav tsum tsis pub dhau ± 1.5 degree;
Kev ntsuas kub nce: Pib cov cuab yeej kuaj thiab khiav mus rau qhov chaw ua haujlwm ruaj khov. Saib xyuas seb qhov kub ntawm qhov nkhaus nce zoo li tsis muaj dhia lossis lag, thiab paub meej tias lub sij hawm thermal teb tsawg dua lossis sib npaug li 5s;
Vibration test (optional): In the low-speed operating state of the equipment, lightly touch the probe. If the reading fluctuates >± 0.5 degree, lub caij nplooj ntoos hlav siab lossis qhov chaw tiv tauj yuav tsum tau rov kuaj dua -.
Installation Precautions thiab Risk Avoidance
Tsis txhob ntaus qhov kev sojntsuam: Tsis txhob siv rauj lossis cov khoom siv hlau los tsoo lub mounting bolts lossis cov raj tiv thaiv, vim qhov no yuav ua rau lub thermocouple tawg lossis txheej rwb thaiv tsev puas;
Tsis txhob nruab rau ntawm qhov chaw muaj zog vibration: xws li cua compressors, tshuab stamping, siab -ceev motors, thiab lwm yam., ntev li - vibration yuav ua rau lub caij nplooj ntoos hlav qaug zog thiab puas;
Do not use the standard type at high temperatures (>400℃): Rau siab - qhov kub thiab txias ib puag ncig, yuav tsum xaiv cov qauv tshwj xeeb nrog Inconel springs thiab ceramic rwb thaiv tsev;
Tsis txhob siv cov qauv uas tsis muaj kev tiv thaiv nyob rau hauv cov av noo los yog corrosive gases: IP65 los yog siab dua tiv thaiv qib los yog tawg- hom pov thawj (Ex d IIC T6) yuav tsum tau xaiv;
Tsis txhob rov qab siv lub caij nplooj ntoos hlav deformed: Txawm tias qhov zoo li tsis muaj kev puas tsuaj, txo elasticity yuav ua rau kev sib cuag tsis zoo, thiab tag nrho lub caij nplooj ntoos hlav module yuav tsum tau hloov.
Cov Txheej Txheem Txhim Kho thiab Kev Txhim Kho
Txhua 3-6 lub hlis los yog thaum lub sij hawm txhua yam khoom kaw thiab tu, xyuas seb lub caij nplooj ntoos hlav preload tau txo. Qhov no tuaj yeem ua tiav los ntawm kev sim tactile: yog tias lub caij nplooj ntoos hlav tsis rov zoo tom qab loosening lub bolt, nws yuav tsum tau hloov;
Thaum disassembling, tsuas yog loosen lub bolts, tsis txhob ncaj qha rub tawm qhov sojntsuam kom tsis txhob tawg cov xov hlau;
Thaum reinstalling, qhov saum npoo yuav tsum tau muab ntxuav dua, thiab nws yuav tsum tsis txhob reassembled ncaj qha los tiv thaiv cov tsub zuj zuj ntawm oxide txheej los ntawm kev cuam tshuam cov tshav kub conduction;
Txhua qhov kev sojntsuam raug pom zoo kom rov siv dua tsawg dua lossis sib npaug li 50 zaug. Tom qab ntawd, nws raug nquahu kom hloov tag nrho chav tsev kom paub meej qhov ntsuas qhov ntsuas kub thiab kev nyab xeeb.
Kev teeb tsa lub caij nplooj ntoos hlav-loaded thermocouples qhov tseem ceeb yog "hloov lub cev embedding nrog txhua yam siab." Tus yuam sij rau kev txhim kho kev ua tiav yog nyob rau hauv kev sib cuag nrog lub siab, huv si, thiab meej torque. Kev txhim kho kom raug tuaj yeem txhim kho qhov ntsuas kub kom raug ntau dua 40%, thiab yog ib kauj ruam tseem ceeb hauv kev ua tiav qhov tsis yog - kev saib xyuas kev twv ua ntej.
