Qhov kev pab cuam lub neej ntawm Profile A75 rail yog dab tsi?

Qhov kev pab cuam lub neej ntawm Profile A75 rail yog dab tsi?

Kev pab lub neej ntawm lubProfile A75 railtsis yog txhais los ntawm tus naj npawb ntawm xyoo tas li tab sis yog ntsuas los ntawm tag nrho cov tonnage ntawm kev xa tawm thiab qib ntawm kev hnav ntawm lub taub hau tsheb ciav hlau. Nyob rau hauv tus txheej txheem kev khiav hauj lwm tej yam kev mob nyob rau hauvnruab nrab -cov haujlwm crane, siab - zoo DIN 536 A75 rail yuav nyob nruab nrab ntawm10 mus rau 25 xyoo. Txawm li cas los xij, qhov kev ua neej no yog nyob ntawm A75 rail hardness, qhov tseeb ntawm kev teeb tsa, thiab qhov zaus ntawm kev saib xyuas.

Yam tseem ceeb cuam tshuam rau A75 Kev Pabcuam Lub Neej

• Khoom siv zog:Ua los ntawm siab - lub zog steel (feem ntau900A qib), A75 rails muab siab hardness (Ntau dua lossis sib npaug rau 260 HB), txo hnav los ntawm kwv yees li 50% piv rau cov pa tsheb ciav hlau.

• Hardening Treatments:Lub taub hau -hardened A75 rails tuaj yeem ncav cuag qhov nyuaj ntawm qhov chaw340-380 HB, nce lawv lub neej nyob rau hauv siab - hnav ib puag ncig (xws li cov chaw nres nkoj) ntau dua 50% piv rau tus qauv A75 rails.

• Cov xwm txheej ua haujlwm:Nyob rau hauv siab - zaus, hnyav- cov haujlwm ua haujlwm - xws li chaw nres nkoj thawv cranes (STS / RTG), metallurgical nroj tsuag, lossis cov chaw khaws khoom tsis khoom- txoj kev tsheb ciav hlau yuav raug rau siab ntsug loads (tshaj 100+ tonnes) thiab cov quab yuam tseem ceeb, uas tuaj yeem txo nws lub neej tag nrho mus txog 20 xyoo.

• Kev tu:Kev tshuaj xyuas tsis tu ncua, lubrication, thiab kho tam sim ntawd (xws li, kev sib tsoo kom kho qhov tsis zoo) yog qhov tsim nyog kom ncav cuag qhov siab tshaj plaws kev pab cuam lub neej.

Ua raws li European DIN 536 tus qauv, A75 rail profile yog txiav txim siab thaum kawg ntawm nws lub neej kev pab cuam thaum lub ntsug hnav ntawm lub taub hau mus txog kwv yees li 10-15% ntawm nws thawj qhov siab, los yog thaum lateral deformation cuam tshuam kev nyab xeeb ntawm lub overhead cranes.

Lub neej kev pab cuam ntawm A75 crane rail yuav txuas ntxiv los ntawm kev siv rail fasteners?

Yog lawm, kev pabcuam lub neej ntawm A75 crane rail tuaj yeem txuas ntxiv los ntawm kev siv cov tsheb ciav hlau tsim nyog, zoo lirail clampthiabroj hmab pads. Cov txheej txheem fastening kom zoo txo ​​kev vibration, xyuas kom ruaj khov, thiab txo qis kev ntxhov siab ntawm txoj kev khiav, uas tiv thaiv kev qaug zog thaum ntxov thiab hnav hauv hnyav - cov ntawv thov kev lag luam.

Txoj hauv kev tseem ceeb fasteners thiab tu ncua A75 Rail Life:

• Resilient Fastening Systems:Siv tshwj xeeb crane rail clips thiab pad systems absorbs cuam tshuam, txo kev co, thiab pab tswj cov loads siab (txog 250 kN), uas yog ib qho tseem ceeb rau maximizing rail ntev.

• Txo Deflection:Ua kom muaj kev ruaj ntseg anchoring nrog cov fasteners kom zoo tiv thaiv kev tsheb ciav hlau, tiv thaiv ob qho tib si crane thiab txoj kev khiav los ntawm kev ua tsis tiav ntxov.

• Proactive Maintenance:Pairing zoo fasteners nrog kev soj ntsuam tsis tu ncua, rail lubrication, thiab sib tsoo -uas tuaj yeem rov qab tau 80-90% ntawm kev pabcuam lub neej los ntawm kev tshem tawm qhov tsis xws luag - txuas ntxiv tag nrho lub neej ntawm A75 rails.

• Lub taub hau -Hardening:Thaum tsis yog ib lub fastener, xaiv lub taub hau- hardened A75 rail (feem ntau mus txog 340-380HB) muab 50% nce ntawm hnav tsis kam, ua hauj lwm nrog kev ruaj khov fastening kom ntev lifespan.

Rau qhov ntev tshaj plaws, tshwj xeeb tshaj yog nyob rau hauv siab -load chaw nres nkoj lossis ib puag ncig kev lag luam,GNEE RAILcov lus pom zoo qhia txog qhov tseem ceeb ntawm kev siv siab -cov khoom tensile thiab cov khoom siv A75 rail tsim nyog.

FAQ

• Dab tsi yog qhov nruab nrab lifespan ntawm A75 rail nyob rau hauv ib lub nkoj nkoj?

Hauv cov chaw nres nkoj hiav txwv, qhov chaw muaj corrosion thiab cov khoom thauj siab, lub neej kev pab cuam feem ntau yog 10-15 xyoo. Siv A75 lem nrog lub taub hau-hardening thiab tshwj xeeb Surface Treatment tuaj yeem txuas ntxiv qhov no ntau.

• Yuav ua li cas kuv thiaj paub thaum lub sij hawm hloov kuv A75 lem?

Koj yuav tsum saib xyuas A75 rail specifications rau ntsug hnav. Thaum lub taub hau qhov siab tau txo qis dua 10%, lossis yog tias koj pom qhov tawg tseem ceeb (spalling), cov ntu A75 khiav yuav tsum tau hloov.

• Puas yog qhov siab dua A75 rail hardness ib txwm txhais tau tias lub neej ntev?

Feem ntau, yog. Qhov siab dua A75 rail hardness (zoo li R350HT) tiv taus hnav thiab deformation zoo dua. Txawm li cas los xij, nws yuav tsum muaj kev sib npaug nrog lub zog kom tsis txhob nkig tawg hauv siab - cuam tshuam cov rooj sib dhos hnyav.

• Kuv puas tuaj yeem txuas lub neej ntawm kuv DIN 536 A75 rail los ntawm vuam?

Hnav lub taub hau qee zaum tuaj yeem tsim los ntawm vuam, tab sis rau lub luag haujlwm hnyav crane rail, qhov no feem ntau yog kho ib ntus. Nws feem ntau yog tus nqi ntau dua - siv tau thiab nyab xeeb dua los hloov A75 profile thaum nws ncav cuag nws qhov kev txwv.

• Lub tsheb ciav hlau cuam tshuam li cas rau lub neej kev pab cuam ntawm Rail A75?

Reinforced pads / rail pads yog qhov tseem ceeb. Lawv nqus cov shocks los ntawm overhead cranes, uas tiv thaiv A75 steel rail los ntawm kev tawg thiab tiv thaiv ib leeg daim hlau los ntawm kev ua tsis tiav ntxov.

• Vim li cas kev teeb tsa kev sib raug zoo yog qhov tseem ceeb rau A75 txoj kev tsheb ciav hlau ntev?

Txawm tias me ntsis misalignment nyob rau hauv lub A75 runway seem ua rau lub crane log "sib tsoo" tiv thaiv lub taub hau rail. Qhov kev sib txhuam sab nraud no yog qhov ua rau ua tsis tiav ntxov rau DIN tus qauv Steel rail systems.
