FR-damper-ka-hortagga gariirka oo ka saaraya soo noqnoqda gariirka kala duwan
Sharaxaad:
Nooca FR Preformed Vibration Damper waxaa caadi ahaan loo isticmaalaa in lagu xakameeyo gariirada kirishbooyada sare & OPGW.Dhererka gariirku wuxuu leeyahay dhererka fiilada Messenger-ka ee birta.Laba miisaan oo macdan ah ayaa ku dheggan darafyada fiilada farriinta.Xajinta xudunta u ah, ee ku dheggan fiilada messenger-ka, ayaa loo isticmaalaa in lagu rakibo damper-ga gariirka kooraha sare.
Damper-ga gariirka asymmetrical waa nidaam resonance badan oo leh qoyaan dabiici ah.Tamarta gariirku waxa ay ku kala firdhisaa is jiid jiid dhex mara fiilada Messenger-ka ee ku wareegsan wareegyada dhawaaqa ee damper gariir.Iyadoo la kordhinayo tirada resonances ee damper iyadoo la isticmaalayo naqshad asymmetrical ah iyo kordhinta awoodda qoyaan fiilada messenger-ka dambarka gariirka ayaa wax ku ool u ah dhimista gariirka inta jeer ee ballaaran ama kala duwanaanshaha xawaaraha dabaysha.
Astaamaha:
1.Pre-stranded silig loogu talagalay rakibaadda birta aluminiumka ah
2.Easy rakibaadda (qalab looma baahna)
3. Ammaan ah oo la isku halayn karo (wax dhibaato ah uma geysan fiilooyinka)
4. Dayactir la'aan (malaha boolal dabacsan)
5. Kharashka rakibaadda hooseeya (kaliya toban ilbiriqsi si loo rakibo badeecad)
6.Aqbalid iyo fiirsi fudud oo la isku halayn karo
Isbarbardhigga dambarka ka-hortagga gariir-gariir hore loo sameeyay iyo damper-gariir-ilaaliye-dhaqameed:
Taangiyada ka hortagga gariir dhaqameedka waxaa lagu hagaajiyaa boolal.Inta lagu jiro rakibidda, shaqaalaha dhismuhu waa inay ku qalabaysan yihiin furayaasha qulqulka.Marka kooxda dhismuhu aysan haysan qalabkan, xoog xad dhaaf ah ama yar ayaa dhacaya.Dhaqdhaqaaqa xad-dhaafka ah ayaa laga yaabaa inuu waxyeelo u geysto fiilooyinka ama boolalka;haddii qulqulku yar yahay, xoogga qodista ee u dhexeeya damper-ga-gariirka iyo fiilooyinka ma buuxin karaan heerka.
Damper-ka-hortagga gariirka ee hore loo sameeyay wuxuu meesha ka saarayaa faa'iido darrada damper-ga-gariir-ka-hortagga ee kor lagu sharraxay.Ku rakibida damper-ka-hortagga-gariir-ka-hortagga ah waxaa lagu dhammaystiri karaa gacmo qaawan iyada oo aan loo baahnayn qalab hawleed, rakibiddu waa mid ku habboon oo degdeg ah, kharashka dhismuhuna waa yar yahay.
Qabashada u dhaxaysa fiilada hore loo sameeyay iyo hagaha damper-ga-gariir-ka-hortagga ayaa si siman loo qaybiyaa dhererka 30 ilaa 60 mm, kaas oo ka fogaanaya xoogga saarista fiilada.
Intaa waxaa dheer, tayada rakibaadda ee preformed damper-ka-hortagga gariirku waa la arki karaa oo lagu xukumi karaa dhulka oo leh telescope, kaas oo si weyn u yareynaya dhibka iyo kharashka aqbalaadda mashruuca oo aad u wanaajinaya kalsoonida aqbalaadda.
Marka la soo koobo, faa'iidooyinka damper-ka-hortagga gariirrada ee hore loo sameeyay waxaa lagu soo koobi karaa sida soo socota:
1. Rakibaadda fudud iyo kharashka rakibaadda hoose;
2. Ammaan oo la isku halayn karo, dayactir la'aan;
3. Waxtarka dhismaha sare, aqbalida ku habboon oo la isku halleyn karo.

1. Madaxa dubbe waa shubista birta cawl, xajin siligguna waa shubida aluminium alloy, taas oo ka fogaanaysa luminta hysteresis oo leh saamayn badbaadinta tamarta. |
