Yuav ua li cas Rail Fastening Systems raug cais
Txhua lub tsheb ciav hlau fastening system muaj tib txoj haujlwm: tuav lub tsheb ciav hlau, tuav lub ntsuas, hloov lub log load rau hauv lub txaj pw, thiab tswj kev txav mus ntev, thaum tso cai txaus elasticity rau cov tsheb ciav hlau ua pa nrog qhov kub thiab txias. Cov kab ke raug cais los ntawm lawv cov haujlwm tseem ceeb. Elastic clip systems nias lub hauv paus kev tsheb nqaj hlau tiv thaiv lub ncoo nrog lub caij nplooj ntoos hlav quab yuam ntawm cov hlau clip. Bolted clamp systems siv lub ntsiab clamp nruj los ntawm bolts thiab ceev, thiab xa cov clamping quab yuam los ntawm lub zog nruj. Spike systems thauj cov tsheb ciav hlau los ntawm kev khi phaj rau hauv lub txaj pw nrog cov dev spikes lossis ntsia hlau spikes. High -cov tshuab ceev sib xyaw ua ke cov ntsiab lus no nrog rwb thaiv tsev, ntsuas kev hloov kho thiab elastic pads rau lub siab ntev ntawm kev khiav tsis muaj ballast. Nyob rau hauv cov tsev neeg no, cov kev teeb tsa tshwj xeeb raug paub los ntawm lawv cov npe, thiab cov lus hauv qab no muab cov npe ntawm cov khoom sib xws.
Elastic Clip Fastening System
Elastic clip systems yog cov tsev neeg siv dav tshaj plaws ntawm cov kab tseem ceeb. Cov clip yog ua los ntawm lub caij nplooj ntoos hlav steel, nws cov ntiv taw nias ntawm lub hauv paus kev tsheb nqaj hlau, thiab nws ob txhais ceg dais ntawm lub xub pwg nyom los yog cov ntawv qhia. Cov txheej txheem kev teeb tsa rau tsev neeg no siv ob qhov nro clips rau ib tus neeg pw tsaug zog, ob lub ntsia hlau spikes, tiaj tus ntxhua khaub ncaws, yas dowels, daim phiaj qhia thiab ib lub tsheb ciav hlau.

Spike Fastening Systems
Spike systems yog cov tshuaj ib txwm siv rau cov ntoo - pw tsaug zog. Ib lub phaj khi zaum ntawm lub tsheb ciav hlau thiab tus neeg pw tsaug zog, faib cov khoom thauj thiab tuav lub hauv paus kev tsheb nqaj hlau, thiab aub spikes los yog txiav spikes yog tsav los ntawm lub phaj qhov rau hauv cov ntoo. Tib tsev neeg suav nrog cov ntsia hlau ntsia hlau ntsia hlau, uas cov ntsia hlau ntsia hlau ntsia rau hauv cov yas dowel lossis lub qhov ua ntej-drilled, muab lub zog clamping thiab tshem tawm yooj yim dua.

High -Speed Rail Fastening Systems
High- cov kab ceev yuav tsum tau ceev cov kab ke nrog kev ntsuas nruj, rwb thaiv tsev hluav taws xob, thiab cov khoom siv elastic uas ua rau muaj kev cuam tshuam ntawm siab - lub log ceev. WJ-7 thiab WJ-8 systems thiab hom V system yog cov kev teeb tsa tshwj xeeb siv rau lub luag haujlwm no. Lawv cov khoom sib xyaw ua ke zoo sib xws hauv cov hauv paus ntsiab lus: rail clips ntawm lub caij nplooj ntoos hlav steel, ntsia hlau spikes, rail insulators, qhia daim hlau, rail pads thiab yas dowels, teem rau ceev, raug installation ntawm ballasted los yog ballastless khiav.

Tsis tas li ntawd, lub nrig- zoo li tus clip kaw tau siv dav hauv South African railway networks thiab cov tebchaws nyob sib ze, suav nrog peb qhov chaw: rail clips, base plates thiab insulating steel pins. Nws yog ib qho yooj yim, muaj zog tsim rau nruab nrab ceev freight thiab cov neeg caij tsheb kab.
Kev Taw Qhia Xaiv
Cov chav kawm kab: siab- cov kab ceev siv cov WJ lossis hom V teeb tsa; Cov kab lus siv cov tshuab elastic clip.
Axle load: hnyav-haul thiab corrosive ib puag ncig nyiam bolted clamp systems nrog siab clamping quab yuam.
Hom pw tsaug zog: cov ntoo pw tsaug zog siv cov kab ke; cov neeg pw tsaug zog siv cov tshuab kaw lus nrog cam khwb cia- hauv lub xub pwg nyom lossis dowels.
Rwb thaiv tsev: khiav- cov kab hluav taws xob xav tau cov tshuab nrog PA66 insulators thiab insulating rail pads.
Kev Kho: xaiv cov tshuab uas nws cov ntiv taw ntiv taw load tsis nyob ntawm qhov tseeb bolt torque, kom yooj yim rau kev teeb tsa.
Cov lus nug nquag
Q1: Dab tsi yog qhov txawv ntawm qhov elastic clip kaw lus thiab bolted clamp system?
Ib qho elastic clip system tuav lub tsheb ciav hlau nrog lub caij nplooj ntoos hlav quab yuam ntawm cov hlau clip, yog li lub clamping quab yuam yog teem los ntawm tus qauv tsim. Lub kaw lus bolted clamp siv cov khoom clamp nruj nruj los ntawm bolts, yog li lub clamping quab yuam yog tswj los ntawm torque thiab feem ntau siab dua.
Q2: Lub kaw lus fastening twg yog siv rau cov ntoo pw?
Cov ntoo pw tsaug zog feem ntau yog siv cov kab ke dav dav: khi phaj nyob rau hauv txoj kev tsheb ciav hlau thiab dev spikes los yog ntsia hlau spikes tsav mus rau hauv cov ntoo. Screw spikes yog qhov zoo dua qhov kev tshem tawm thiab rov- zawm yuav tsum.
Q3: Lub luag haujlwm ntawm cov yas dowel hauv lub kaw lus clip yog dab tsi?
Cov yas dowel yog cam khwb cia los yog glued rau hauv lub sleeper thiab tau txais cov ntsia hlau ntsia hlau loj. Nws tiv thaiv cov pob zeb los ntawm kev tawg, muab xov anchorage, thiab tuaj yeem hloov tau yog tias cov xov puas lawm.
Q4: Vim li cas siab - cov tshuab ceev siv cov insulators thiab cov ntaub thaiv kev tsheb ciav hlau?
Insulators thiab pads tsim cov hluav taws xob rwb thaiv tsev ntawm cov tsheb ciav hlau thiab cov neeg pw tsaug zog rau cov kab hluav taws xob thiab kev tswj xyuas tam sim no, thaum lub elastic pad damps cuam tshuam thiab tiv thaiv cov slab los ntawm siab - zaus vibration.
Q5: Puas yog lub kaw lus fastening tsim rau ib qho kev tsheb ciav hlau haum rau lwm qhov?
Tsis yog tsis muaj kev txheeb xyuas kev sib raug zoo. Cov ntiv taw ntiv taw thiab kev tsheb ciav hlau sib txuas yog nyob ntawm qhov dav thiab qhov profile; lub kaw lus sib phim rau 150 mm lub hauv paus kev tsheb nqaj hlau yuav tsis zaum kom raug ntawm qhov nqaim.
