CGRSP Daim Ntawv Qhia Tag Nrho thiab Txhais
CGRSP sawv cev rau Composite Grooved Rubber Sole Plate. Nws yog lub ncoo muab tso rau ntawm lub hauv qab ntawm txoj kev tsheb ciav hlau ko taw thiab sab saum toj ntawm tus neeg pw tsaug zog, ntawm ob qho tib si pob zeb thiab ntoo pw tsaug zog, nyob rau hauv txoj kev ua rau Indian Railways xyaum. Lo lus composite qhia txog cov khoom siv, roj hmab, EVA lossis HDPE compounds es tsis yog roj hmab dawb; grooved piav qhia cov qauv molded rau hauv lub phaj; ib lub phaj piav txog nws txoj hauj lwm raws li lub rooj zaum ntawm txoj kev tsheb ciav hlau. Lub phaj muaj ob qhov tuab tuab hauv kev pabcuam, 6.2 hli thiab 10 hli, xaiv los ntawm rail seem, hom pw tsaug zog thiab qag load. Vim tias lub phaj raug tshav ntuj, los nag thiab kub mus rau nws lub neej tag nrho, qhov sib xyaw yuav tsum tiv taus kev laus, kub thiab txias, thiab nyob rau hauv av thiab hauv nroog seem nws kuj tau teev tseg rau kev txo suab nrov.
Vim li cas Grooves thiab Composite Tsim
Cov grooves tsis yog kho kom zoo nkauj. Lawv muab qhov chaw sib xyaw ua ke kom deform tom qab nyob rau hauv load, yog li lub phaj ua raws li lub caij nplooj ntoos hlav es tsis yog ib qho khoom thaiv, uas ua rau nws cov damping efficiency thiab txo qhov nruj ntawm txoj kev tsheb ciav hlau. Cov grooves tseem tso dej thiab ballast nplua kom deb ntawm lub rooj zaum, tiv thaiv lub txaj pw thiab phaj nws tus kheej los ntawm kev sib tsoo. Cov khoom sib xyaw ua ke, roj hmab lossis cov thermoplastic nrog cov khoom ua kom haum, tso cai rau cov chaw tsim khoom teeb tsa qhov tawv, tawv thiab rwb thaiv tsev ntawm nws tus kheej, yog li tib daim duab tuaj yeem muab nkag rau hauv cov khoom siv softer rau kev vibration- cov seem rhiab thiab ib qho nyuaj rau hnyav - lub luag haujlwm thauj. Lub creep tsis kam ntawm cov compound tseem ceeb ntawm turnouts, qhov twg lub phaj pom lateral loading los ntawm kev hloov txav, uas yog vim li cas CGRSPs tau teev nrog zoo hluav taws xob thiab creep kuj siv rau hauv cov ntsiab lus thiab hla.
Plaub Txoj Haujlwm Tseem Ceeb ntawm CGRSP
Shock Absorption
Lub phaj damps qhov cuam tshuam ntsug ntawm txhua lub log hla, tiv thaiv lub rooj zaum pw tsaug zog los ntawm pounding thiab txo cov kev co xa mus rau hauv lub trackbed thiab ib puag ncig hauv av.
Load Distribution
Nws kis tau lub tsheb loj thauj khoom los ntawm txoj kev tsheb ciav hlau hla ntawm qhov chaw pw tsaug zog tag nrho, tiv thaiv kev ntxhov siab uas ua rau cov neeg pw tsaug zog thiab ua rau lub rooj zaum.
Hluav taws xob rwb thaiv tsev
Nws cais txoj kev tsheb ciav hlau los ntawm tus neeg pw tsaug zog yog li qhov tsis txaus ntseeg tam sim no tsis tuaj yeem nkag mus rau hauv cov qauv kev khiav, ua kom lub teeb liab hluav taws xob txhim khu kev qha, uas yog qhov yuav tsum tau ua ntawm hluav taws xob thiab taug qab- cov kab hluav taws xob.
Track Stability
Los ntawm kev tuav lub elastic zoo sib xws nyob rau hauv txoj kev tsheb ciav hlau, lub phaj pab tswj kev taug qab geometry thiab txo tus nqi ntawm fastenings txaj nyob rau hauv thiab loosen, uas tseem ceeb nyob rau hauv siab - ceev thiab hnyav - thauj seem tib yam.

Cov paib roj hmab yog cov qauv damping rau mainline sleepers, HDPE daim hlau raug xaiv qhov twg hardness thiab hnav tsis kam tswj, thiab EVA daim hlau ua ke siab elongation nrog zoo heev rwb thaiv tsev rau conformable zaum. Cov phaj tuaj yeem muab grooved los yog tiaj, nyob rau hauv qhov ntau thiab tsawg thiab cov qauv tsim uas yuav tsum tau muaj rau cov kab tsheb ciav hlau thiab cov neeg pw tsaug zog, thiab cov txiaj ntsig saum toj no yog cov ntaub ntawv tsim khoom tsim nyog raws li kev siv fastening - system yuav tsum tau.
Xaiv CGRSPs rau Rail thiab Sleeper Combinations
Kev xaiv pib nrog ntu kev tsheb nqaj hlau. Daim phiaj rau UIC54 thiab UIC60 rail, thiab rau BS 80R thiab 100R seem ntawm cov kab sib dua, yog dimensioned rau txoj kab dav dav; lub 6.2 hli phaj yog tus qauv rau kev ua vaj tse- pw tsaug zog mainline khiav, thiab 10 hli phaj yog siv nyob rau qhov twg ntxiv kev sib haum xeeb los yog damping. Cov ntoo pw tsaug zog coj tib lub phaj tsev neeg, nrog rau cov rooj zaum npaj tiaj tus kom lub phaj dais sib npaug. Ntawm cov choj, cov pob qij txha nthuav dav thiab cov kev hloov pauv, cov phaj specification raug kuaj xyuas qhov kev nthuav dav ntawm fastening, vim hais tias lub phaj yog ib feem ntawm fastening los ua ke thiab yuav tsum tsis txhob hloov cov ntiv taw load ntawm clips. Rau kev taug qab- cov kab hluav taws xob, paub meej tias qhov rwb thaiv tsev tsis kam ntawm cov khoom siv; rau cov ntug dej hiav txwv thiab cov cheeb tsam kub, paub meej tias kev laus tiv thaiv ntawm cov compound; thiab rau cov tunnels thiab hauv nroog, ntxiv cov suab nrov- yuav tsum tau txo. Muab cov rail seem, hom pw tsaug zog, qag load thiab ib qho kev taw qhia yuav tsum tau rau tus neeg muag khoom yields qhov tseeb phaj nyob rau hauv ib tug iteration.
Cov lus nug nquag
Qhov txawv ntawm CGRSP thiab GRSP yog dab tsi?
GRSP yog lub ntsiab lus dav dav, Grooved Rubber Sole Phaj; CGRSP qhia txog kev tsim vaj tsev sib xyaw, uas npog cov roj hmab, EVA thiab HDPE cov khoom sib txuas tsis yog ib qho yooj yim - roj hmab tsim.
Dab tsi thickness yuav tsum tau siv rau cov pob zeb pw?
6.2 hli yog tus qauv rau 52 kg / m thiab 60 kg / m rail ntawm pob zeb pw; lub 10 hli phaj yog siv qhov twg tus tsim hu rau kev daws teeb meem ntau dua los yog ntxiv damping.
CGRSPs puas tuaj yeem siv rau ntawm cov ntoo pw?
Yog lawm. Lub phaj yog muab tso rau ntawm lub rooj zaum pw tsaug zog hauv qab txoj kev tsheb ciav hlau kom ntev lub neej pw tsaug zog, nrog rau lub rooj zaum hnav kom lub phaj dais tusyees thiab cov ntiv taw fastening yog khaws cia.
Cov grooves puas cuam tshuam rau hluav taws xob rwb thaiv tsev?
Tsis yog. Cov rwb thaiv tsev yog cov cuab yeej ntawm qhov sib xyaw nws tus kheej, thiab cov grooves hloov tsuas yog tus cwj pwm ntawm txhua yam; grooved daim hlau ua tau raws li qhov kev tiv thaiv kev tiv thaiv tib yam li daim hlau dawb ntawm tib qho chaw.
Yog vim li cas creep resistance teev rau turnout daim hlau?
Nyob rau hauv turnouts lub phaj pom lateral loading li keyboards txav thiab tsheb ciav hlau hla; ib lub phaj nrog tsis zoo creep tsis kam squashes sideways nyob rau hauv qhov chaw thau khoom, loosens lub rooj zaum rail thiab cuam tshuam qhov hloov geometry.
