Kev txhim kho kom raug ntawm cov khoom sib txuas sensor adapter cables yog ib kauj ruam tseem ceeb hauv kev ua kom lub teeb pom kev ncaj ncees, kev ruaj ntseg, thiab kev cia siab ntev -. Kev teeb tsa tsis raug tuaj yeem ua rau tsis yog tsuas yog cuam tshuam kev sib txuas lus thiab cov ntaub ntawv cuam tshuam tab sis kuj tseem tuaj yeem ua rau cov khoom siv tsis raug lossis tsim teeb meem kev nyab xeeb. Cov hauv qab no yog cov lus qhia kev teeb tsa raws li cov qauv kev lag luam thiab cov kev qhia tshwj xeeb ntawm cov tuam txhab ua lag luam.
I. Ua ntej-Kev Npaj Kev Txhim Kho: Tshawb xyuas kev sib raug zoo thiab ib puag ncig
|
Yam khoom |
Yuav tsum muaj thiab cov txheej txheem |
|
Kev xaiv Cable |
Xyuas kom meej tias tus qauv adapter cable yog qhov sib xws nrog lub sensor interface (M12/M8/D-sub), coding (A/D/L), thiab cores (3/4/5/8 cores); muab qhov tseem ceeb rau cov kab hluav taws xob uas muaj lub tsho PUR ua ke nrog ob lub- txheej tiv thaiv txheej txheem (braided + aluminium ntawv ci). |
|
Kev soj ntsuam ib puag ncig |
Inspect the installation area for potential sources of strong electromagnetic interference (e.g., frequency converters, motors), high-temperature heat sources (>60 degree), roj paug, lossis dej noo ntau dhau; Yog tias muaj cov xwm txheej zoo li no, txhim kho cov kav hlau tiv thaiv lossis thaiv cov ntaub thaiv npog. |
|
Kev npaj cuab yeej |
Hlau strippers, torque wrench (qhov tseeb: ± 0.1 N·m), multimeter, rwb thaiv tsev tiv thaiv tester (500V DC), tshav kub-shrink tubing, sealing compound, thiab cable ties. |
Cov Lus Qhia Tseem Ceeb: Tsis txhob siv tus qauv hluav taws xob lub pliers rau cov hlua khi, vim qhov no tuaj yeem ua rau cov txheej thaiv sab hauv los yog cov neeg xyuas pib puas tsuaj; kev siv cov cuab yeej tshwj xeeb crimping yog pom zoo rau kev tuav IDC lossis tus pin- hom kev txiav tawm.
II. Cov kauj ruam ntawm kev teeb tsa: Kauj ruam-los ntawm- Cov txheej txheem txheej txheem (Siv M12 Interface ua piv txwv)
1. Cable Pre- ua
Siv cov hlau strippers tshem tawm 10-15 hli ntawm lub tsho sab nrauv, saib xyuas kom tsis txhob ua rau cov txheej thaiv sab hauv;
Quav cov ntaub thaiv npog rov qab, tom qab ntawd siv cov ntawv hlau hlau los yog daim kab xev tooj liab kom ruaj khov rau cov ntaub thaiv npog ntawm lub hauv paus; tshem tawm cov khoom siv ntau dhau los tiv thaiv cov hlua khi;
Sawb 2-3 hli ntawm rwb thaiv tsev los ntawm txhua tus tub ntxhais hlau; Yog hais tias cov hlau cores qhia cov cim ntawm oxidation, maj mam txhuam lawv nrog cov ntawv xuab zeb zoo kom txog thaum cov xim hlau rov qab.
2. Hlau Core Termination
Ntxig cov hlau cores rau hauv qhov sib txuas lub davhlau ya nyob twg raws li daim duab thaiv (feem ntau xim -coded: Brown=Power +, Dub=GND, Daj / Dawb=Teeb liab).
Crimp- hom: Siv cov cuab yeej tshwj xeeb crimping los siv txawm tias lub siab, kom ntseeg tau tias tus neeg xyuas pib thiab lub davhlau ya nyob twg muaj kev sib raug zoo.
IDC- hom (piv txwv li, HARTING): Ntxig cov tub ntxhais hlau rau hauv lub qhov thiab nias nrog ib lub cuab yeej kom txog rau thaum qhov sib txawv "nias" yog hnov, paub meej tias nws yog xauv rau hauv qhov chaw.
Solder- hom: Siv cov hlau soldering nrog lub zog ntsuas tsawg dua lossis sib npaug ntawm 45W, ua kom lub sijhawm soldering nyob rau hauv 5 vib nas this; xyuas kom lub solder sib koom yog du thiab tsis muaj burrs. Tsis txhob rub cov hlau tam sim ntawd tom qab soldering.
3. Kev sib dhos vaj tse thiab kev sib khi
Ntxig cov khoom siv sab hauv rau hauv vaj tse, ua kom cov txheej thaiv tiv thaiv ua rau 360℃kev sib cuag nrog lub plhaub hlau ntawm lub connector.
Tighten lub tes tsho nruab nrab (Torque: 1 N·m), ces nruj lub tes tsho hauv qab (Torque: 2 N·m).
Siv silicone-raws li sealant rau lub seam ntawm lub cable thiab lub tsev, los yog siv cov cua sov-shrink tubing thiab shrinkage nws siv rab phom kub, kom ntseeg tau tias IP67 tiv thaiv ntsuas.
4. Kev Tiv Thaiv Txheej Txheej Grounding
Kev Siv Hluav Taws Xob / Tsheb: Cov txheej thaiv thaiv siv ib zaug - taw tes hauv av, txuas rau cov cuab yeej hauv av (SGND) tsuas yog ntawm tus maub los / PLC kawg.
Kev Siv Kho Mob: Cov txheej thaiv npog yog tag nrho ntab; Qhov kev sojntsuam kawg yog insulated thiab qhwv, thaum tsuas yog tus tswv tsev kawg txuas rau lub teeb liab hauv av (EG), yog li tshem tawm cov voj voog hauv av.
Grounding ntawm ob qhov kawg yog txwv nruj heev; ua li ntawd yuav tsim cov voj voog hauv av, ua rau muaj teeb meem cuam tshuam lossis overheating thiab burnout ntawm shielding txheej.
Kev Ua Haujlwm Mantra: "Txuas ua ntej, nruj tom qab; xyuas kom cov ntaub thaiv npog txuas ntxiv, khaws cov av cais."
