Nov 11, 2023

Ib qho EMT (Electrical Metallic Tubing) conduit fitting, tseem hu ua EMT connector lossis EMT accessory, yog ib qho khoom siv siv hauv hluav taws xob sib txuas, ruaj ntseg, lossis hloov EMT conduit. EMT conduit fittings ua lub luag haujlwm tseem ceeb hauv kev muab txoj hauv kev ruaj ntseg thiab nyab xeeb rau cov xaim hluav taws xob thiab cov xaim hluav taws xob, thaum tseem pab txhawb kev sib txuas ntawm cov kav dej mus rau cov thawv sib txuas, cov ntaub thaiv npog, lossis lwm cov kav dej. Cov fittings no yog qhov tseem ceeb rau kev tsim kom tiav thiab ua raws li cov kav dej hluav taws xob. Qee yam EMT conduit fittings suav nrog:

Teem-Screw Connectors:Teem-screw connectors yog siv los txuas EMT conduit rau hlws ris thawv, enclosures, los yog lwm yam conduits. Lawv muaj cov ntsia hlau (set screws) uas, thaum nruj, ruaj ntseg rau hauv qhov chaw. Teem-screw connectors yog ib qho yooj yim rau nruab thiab muab ib tug txhim khu kev qha kev twb kev txuas.

Compression Connectors:Compression connectors muaj lub nplhaib compression los yog ferrule uas nruj mus rau EMT conduit thaum lub connector yog ntsia. Qhov kev tsim no tsim lub foob tsis muaj dej thiab feem ntau siv rau hauv qhov chaw ntub dej lossis sab nraum zoov qhov chaw uas muaj dej tsis zoo yog qhov tseem ceeb.

Squeeze Connectors:Squeeze connectors, tseem hu ua Squeeze-Type Connectors, yog tsim los rau kev ceev thiab yooj yim installation. Lawv muaj qhov tsim hinged uas clamps mus rau EMT conduit thaum nyem los yog compressed, tsim kom muaj kev sib txuas ruaj ntseg. Squeeze connectors tsis xav tau kho vajtse ntxiv.

Teem-Screw Couplings:Teem-screw couplings yog siv los koom ob EMT conduits ua ke. Lawv tau teeb tsa cov ntsia hlau rau ntawm ob qhov kawg, tso cai rau koj kom ruaj ntseg ob EMT txuas hauv qhov txuas. Teem-screw couplings feem ntau yog siv los txuas cov kab txuas txuas lossis txuas cov kab txuas txuas.

Locknuts:Locknuts yog siv nrog rau lwm yam EMT fittings, feem ntau nyob rau hauv kev ruaj ntseg conduit rau hlws ris thawv los yog enclosures. Lawv xov rau hauv lub raj xa dej thiab muab cov ntsiab lus txuas ruaj ntseg thaum nruj tiv thaiv lub thawv los yog lub thawv.

Conduit Straps:Conduit straps, tseem hu ua ib-lub qhov los yog ob-lub qhov pluaj, yog siv los ruaj EMT conduit rau phab ntsa, qab nthab, los yog lwm qhov chaw. Cov fittings no tiv thaiv lub conduit los ntawm kev txav los yog sagging thiab pab tswj lub conduit txoj hauj lwm.

Bushings:Bushings yog siv los tiv thaiv cov xov hlau los ntawm cov npoo ntse ntawm cov kav dej qhib. Lawv feem ntau muab tso rau hauv qhov kawg ntawm cov kav dej kom tiv thaiv cov hlau puas thiab puas.

Cov EMT conduit fittings no yog tsim los ua kom tau raws li cov kev xav tau tshwj xeeb hauv kev teeb tsa hluav taws xob, suav nrog kev ruaj ntseg thiab txuas cov kav dej, tiv thaiv cov xov hlau, thiab ua kom muaj kev ua raws cai. Qhov kev xaiv ntawm kev haum yog nyob ntawm qhov kev xav tau ntawm lub installation thiab cov khoom tshwj xeeb uas txuas nrog lossis tiv thaiv.
