1.Kev tawg thiab tawg
Nplooj caij nplooj ntoos hlavCov pob txha feem ntau tshwm sim hauv cov nplooj ntoo lossis cov txheej sab hauv, nthuav tawm raws li pom cov kab nrib pleb lossis ua tiav tawg.
Yam Tseem Ceeb:
-Overloading & Fatigue: Lub sij hawm ntev hnyav los yog rov cuam tshuam ntau tshaj lub caij nplooj ntoos hlav qaug zog txwv, tshwj xeeb tshaj yog nyob rau hauv nplooj lojdaisfeem ntau ntawm cov load.
-Khoom siv & Manufacturing Defects: Inferior caij nplooj ntoos hlav steel (xws li, tsis txausSUP 9los yog qib 50CrVA) lossis kev kho cua sov tsis zoo (xws li, tsis txaus quenching lossis tempering) txo cov khoom toughness.
-Kev Txhim Kho / Kev Kho Tsis Zoo: Tshaj-tightened los yog xoobU-boltsua rau tsis sib xws kev ntxhov siab, thaum tsis muaj lubrication ntawm nplooj nce kev sib txhuam thiab kev ntxhov siab concentration.
2. Deformation thiab Arcuate poob
Cov nplooj hlav tuaj yeem khoov, twist, lossis poob lawv cov duab kos, cuam tshuam rau kev ncua kev nruj thiab lub tsheb ruaj khov.
Yam Tseem Ceeb:
-Kev thauj khoom txawv txav: Kev ua haujlwm tsis tu ncua ntawm qhov chaw ntxhib lossis hloov khoom thauj tsis zoo ua rau muaj kev ntxhov siab hauv cheeb tsam.
-Thermal puas: Qhov sib thooj rau lub tshuab pa lossis cov khoom kub kub ua rau cov hlau tsis muaj zog, ua rau cov yas deformation.
-Kev laus: Kev siv mus sij hawm ntev txo cov hlau elastic modulus, ua rau deformation mus tas li.
3. Loosening thiab txawv txav suab nrov
Hlau rattling los yog squeaking thaum tsav tsheb, feem ntau vim xoob kev sib txuas los yog hnav cov khoom.
Yam Tseem Ceeb:
-Loose Fasteners:U-bolts,nruab nrab bolts, los yog lub caij nplooj ntoos hlav clips loosen, cia nplooj los yog qag kev sib txuas rau hloov thiab rub.
-Hnav Bushings: Cov roj hmab degraded los yog polyurethane bushings nyob rau hauv shackles los yog eyelets tsim ntau clearance, ua rau muaj kev vibration-induced suab nrov.
-Lubrication Failure: Qhuav los yog tsis muaj roj nyob nruab nrab ntawm nplooj tsub kom kev sib txhuam, ua rau squeaks thiab accelerating hnav.
4. Hnav thiab Corrosion
Pom pom grooves, xeb me ntsis, lossis txo qhov tuab ntawm nplooj nplooj.
Yam Tseem Ceeb:
-Environmental Factors: raug rau cov dej noo, ntsev (xws li, txoj kev caij ntuj no), los yog cov tshuaj corrosive ua rau xeb; av nkos thiab khib nyiab nyob rau hauv nplooj vais exacerbate abrasive hnav.
-Txawv txawv Inter-Leaf Sliding: Tsis muaj lubrication los yog deformed nplooj ua rau tsis sib xws zawv zawg, tsim grooves los yog tiaj me ntsis ntawm nplooj nplooj.
5. Elasticity Degradation
Txo load-bearing muaj peev xwm, manifested los ntawm txawv txav tsheb caij qhov siab (xws li, sagging) nyob rau hauvtsis muaj loadlos yog puv load.
Yam Tseem Ceeb:
-Khoom Taw Qhia: Rov ua dua qhov kev vibrations ntau zaus lossis cyclic loading ua rau cov hlau crystalline, txo nws cov elastic txwv.
-Thaum tshav kub kub kho tsis xws luag: Tsis txaus hardening los yog ntau dhau tempering txo lub caij nplooj ntoos hlav modulus ntawm elasticity, impairing nws muaj peev xwm rov qab mus rau nws cov qub zoo.
6. Kev sib dhos tsis zoo
Nplooj springs hloov los ntawm lawv txoj haujlwm raug ntawm lub qag, ua rau lub log tsheb tsis sib xws los yog tsav tsheb sib txawv.
Yam Tseem Ceeb:
-Installation yuam kev: Misalignedcenter ntsia liaj qhov roojqhov los yog tsis raug U-bolt zawm ib ntus thaum hloov pauv ua rau nplooj tsis pom kev.
-Cov Khoom Txhawb Kev Puas Tsuaj: Deformed qag lub caij nplooj ntoos hlav lub rooj zaum lossis tawg shackle brackets yuam lub caij nplooj ntoos hlav tawm ntawm kev sib tw.
Xaus: Kev cuam tshuam thiab kev tiv thaiv
Nplooj caij nplooj ntoos hlavKev ua txhaum ntawm cov tsheb thauj khoom hnyav feem ntau tshwm sim los ntawm kev thauj khoom ntau, cov khoom tsis raug, kev saib xyuas tsis saib xyuas, thiab ib puag ncig yam. Kev tshuaj xyuas tsis tu ncua (piv txwv li, kev kuaj pom qhov tawg, ntsuas qhov siab ntawm qhov ntsuas, ntsuas suab nrov) thiab kev saib xyuas zoo (lubrication, fastener zawm, tiv thaiv xeb) yog qhov tseem ceeb rau kev txo cov kev pheej hmoo. Rau cov ntawv thov hnyav, ua ntej cov ntaub ntawv zoo, ua raws li cov kev txwv thauj khoom, thiab daws cov teeb meem tam sim ntawd tuaj yeem ua rau lub caij nplooj ntoo hlav ntev ntev thiab ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.
