I. Cov tsos mob thiab kev tshuaj xyuas tus qauv
1. Housing Integrity: Ua tib zoo tshuaj xyuas lub tsev kom muaj kev tawg, deformation, puas, lossis corrosion hnyav. Me corrosion yuav tsum tau muab tshem tawm tam sim ntawd thiab repainted rau kev tiv thaiv; corrosion hnyav yuav tsum tau hloov ntawm qhov cuam tshuam.
2. Cov foob pob tawg- pov thawj cov pob qij txha: Tshawb xyuas qhov khoob, qhov dav, thiab qhov roughness ntawm qhov tawg- pov thawj cov pob qij txha kom ntseeg tau tias lawv nyob hauv qhov kev tso cai. Ib qho hnav dhau qhov kev zam txim yuav ua rau tawg - pov thawj kev ua haujlwm tsis ua haujlwm.
3. Transparent Window: Tshawb xyuas lub qhov rais pob tshab ua los ntawm siab - lub zog tempered iav los yog yas tshwj xeeb rau khawb, tawg, lossis puas tsuaj kom pom tseeb meej thiab cuam tshuam.
II. Kev soj ntsuam sealing
1. Cable Inlet Seal: Txheeb xyuas cov roj hmab sealing nplhaib ntawm lub cable inlet kom muaj kev ncaj ncees. Nws yog nruj me ntsis txwv tsis pub siv sealing putty, asbestos hlua, lossis lwm yam kev hloov pauv. Cov roj stains ntawm lub nplhaib sealing yuav tsum tau muab ntxuav kom huv kom tsis txhob muaj kev laus thiab kev puas tsuaj.
2. Cavity Seal: Nws yog txwv tsis pub sau cov kab noj hniav nrog txhua yam khoom, vim qhov no yuav cuam tshuam qhov tawg - pov thawj kev ua haujlwm. Tag nrho cov inlet thiab qhov hluav taws xob gaskets thiab hlau ntxhua yuav tsum tuav lawv lub Hoobkas- kaw qhov xwm txheej, thiab cov txiv ntseej compression yuav tsum tau nruj kom kaw qhov nkag.
3. Kev Tiv Thaiv Kev Ntsuam Xyuas Kev Ntsuas: Rau cov khoom siv ntsuas IP68, 30-feeb immersion test ntawm 1 meter underwater yuav ua tau los xyuas kom meej sealing kev ua tau zoo.
III. Fastener thiab Internal Support Inspection
1. Fastener Condition: Xyuas tag nrho cov bolts thiab ceev kom looseness. Loose fasteners yuav tsum tau nruj tam sim ntawd. Kev hloov pauv lossis cov fasteners uas ploj lawm yog txwv tsis pub.
2. Internal Support Ncej: Tshawb xyuas cov khoom txhawb nqa sab hauv kom ruaj khov kom tsis txhob xoob lossis puas tsuaj rau cov khoom sab hauv vim muaj kev cuam tshuam.
IV. Hluav taws xob kev ua tau zoo thiab kev soj ntsuam kev nyab xeeb
1. Grounding System: Kev sib txuas hauv av ntawm kev tawg- cov khoom pov thawj yuav tsum tau ua tib zoo tshuaj xyuas txhua lub limtiam kom paub meej tias nws ruaj khov thiab kuaj xyuas qhov tawg, corrosion, lossis lwm yam tsis xws luag hauv cov xaim hauv av. Grounding kuj yuav tsum tau ntsuas tsis tu ncua kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau ua, feem ntau tsis tshaj 10Ω.
2. Rwb thaiv tsev kev ua tau zoo: Txhua hli kev ntsuas kev tiv thaiv rwb thaiv tsev yuav tsum tau ua los ntawm kev siv lub ntsuas hluav taws xob tiv thaiv kom ntseeg tau tias cov khoom siv rwb thaiv tsev ua haujlwm zoo.
V. Kev soj ntsuam kev ua haujlwm thiab kev ua haujlwm
1. Pib- nce thiab Kev Ua Haujlwm: Txhua lub sijhawm pib cov khoom siv, saib seb qhov pib- nce li qub thiab seb puas muaj suab txawv txav, kev co, lossis kub dhau thaum ua haujlwm. Yog tias pom muaj qhov txawv txav, lub tshuab yuav tsum tau nres tam sim rau kev tshuaj xyuas.
2. Qhov cua thiab cua sov Dissipation: Tshawb xyuas seb lub qhov cua qhov qhib tsis muaj kev cuam tshuam, seb lub tshuab cua txias puas ua haujlwm zoo li qub, thiab seb lub dab dej kub puas tsis muaj plua plav lossis thaiv.
VI. Kev soj ntsuam raws sij hawm thiab kev txheeb xyuas kev tshaj lij
1. Kev soj ntsuam ib ntus: Nws raug nquahu kom ua haujlwm tsis tu ncua rau lub koom haum kuaj kev tshaj lij los ua qhov kev ntsuam xyuas kev nyab xeeb, suav nrog kev tshuaj xyuas zoo li qub, kev ntsuas hluav taws xob tsis zoo, ntsuas qib kev tiv thaiv, thiab kev pom zoo ntawm pab pawg kub.
2. Kev Ntsuam Xyuas Kev Ua Haujlwm: Rau cov khoom tseem ceeb, kev ntsuam xyuas kev cuam tshuam (xws li lub caij nplooj zeeg dawb, kev cuam tshuam pendulum) thiab kev ntsuas siab zoo li qub (siv 1.5 npaug ntawm kev siv siab rau 10 feeb yam tsis muaj kev ua haujlwm tsis zoo) tuaj yeem ua tau.
