CovDLZ100 series fais fab - tsav log nres(ib txwm kaw, disc- caij nplooj ntoos hlav-braked, hluav taws xob- tso cua tawm- tiv thaiv nres) muaj qhov ua txhaum loj hauv nws lub zog tsav hluav taws xob, lub zog nres nres, thiab cov khoom siv tiv thaiv kev nyab xeeb. Hauv qab no yog nwsfeem ntau fault phenomena, cov hauv paus ntsiab lus, thiab qhov txawv nta, txheeb los ntawm qhov tsis ua haujlwm zaus (los ntawm siab mus rau qis):
1. Kev Tso Tsis Tau (Feem ntau)
Fault Phenomenon: Cov kev sib txhuam hauv ob sab phlu tsis tuaj yeem cais tawm ntawm lub log kawg lub ntsej muag; lub crane taug kev mechanism tsis tuaj yeem pib; qhov txwv hloov pauv tsis muaj kev tso tawm - hauv - qhov chaw teeb liab.
Keeb kwm:
Hluav taws xob tsis ua hauj lwm: Lub cev muaj zog tsis txaus, electromagnet coil burnout, lossis tswj relay daig (tsis hloov lub cev mus rau electromagnet tuav hom).
Mechanical jamming: Disc springs daig vim plua plav txuam, piston qhia lub tes tsho jamming, los yog sib npaug -retraction mechanism tsis ua hauj lwm.
Circuit Court txhaum: xoob thaiv ntawm lub cev muaj zog / electromagnet, los yog txwv hloov actuator misalignment.
Distinguishing Feature: Lub cev muaj zog yuav buzz tab sis tsis tig, los yog tig tab sis tsis tswj lub xeev tso tawm (electromagnet tuav tsis ua hauj lwm).
2. Tsis muaj zog Braking Force (High Risk)
Fault Phenomenon: Lub nres tsis tuaj yeem tiv thaiv lub crane los ntawm kev tsiv los ntawm cov cua muaj zog; lub log swb nyob rau hauv cua load; cov kev sib txhuam hauv ob sab phlu qhia tias hnav tsis sib xws.
Keeb kwm:
Cov teeb meem hauv ob sab phlu: Kev sib txhuam hauv ob sab hauv hnav kom tsawg dua los yog sib npaug li 3 hli, los yog cov roj / plua plav paug ntawm cov ntaub ntawv / lub log.
Caij nplooj ntoos hlav qaug zog: Disc springs poob preload vim ntev - lub sij hawm compression.
Clearance imbalance: Qhov sib npaug -retraction mechanism tsis ua hauj lwm, ua rau uneven clearance ntawm ob sab thiab log (ib sab drags, lwm yam yog xoob heev).
Distinguishing Feature: Lub nres tuaj yeem clamp lub log tab sis tsis tuaj yeem muab qhov ntsuas 135-150 kN static kev sib txhuam quab yuam; hauv ob sab phlu yuav muaj glazing (roj paug) los yog sib sib zog nqus grooves (xuab zeb hnav).
3. Lub cev muaj zog overheating thaum tso tawm
Fault Phenomenon: The release motor becomes hot to the touch (surface temperature >80 degree); lub cev muaj zog mus ncig ua si vim overcurrent; lub rwb thaiv tsev txheej ntawm lub cev muaj zog hlau muaj hnub nyoog sai sai.
Keeb kwm:
Tswj logic tsis ua hauj lwm: Lub cev muaj zog tsis nres tom qab lub nres nres, thiab khiav tsis tu ncua (es tsis txhob hloov mus rau electromagnet tuav).
Voltage abnormality: Fais fab mov voltage siab dhau los yog tsawg dhau (deviating los ntawm ± 5% ntawm tus nqi ntsuas).
Mechanical resistance: Lub cev muaj zog hnav lossis jamming, nce load tam sim no.
Distinguishing Feature: Lub cev muaj zog overheats tsuas yog thaum lub sij hawm tso tawm; Yog hais tias lub electromagnet tuav muaj nuj nqi yog ib txwm, lub cev muaj zog kub poob sai sai tom qab nres.
4. Limit Switch Failure (Common Safety Hazard)
Fault Phenomenon: Tsis muaj teeb liab interlock; lub crane tuaj yeem pib txawm tias lub nres tsis tso tawm, lossis tsis tuaj yeem pib txawm tias thaum tso tawm; cuav tswb ntawm tso tsis ua hauj lwm.
Keeb kwm:
Ib puag ncig corrosion: ntsev pos huab los yog noo noo ua rau tsis zoo ntawm kev sib cuag ntawm kev sib cuag (rau kev siv chaw nres nkoj sab nraum zoov).
Mechanical puas: Actuator dabtsi yog khoov lossis hloov plhaub tawg vim kev co.
Wiring fault: xoob lossis tawg teeb liab xov hlau.
Distinguishing Feature: Lub teeb taw qhia qhov hloov pauv yog kaw lossis flickering; lub kaw lus tswj qhia tau hais tias "brake tsis tso tawm" txhaum txawm tias thaum lub hauv ob sab sib cais.
5. Cov suab nrov txawv txav / vibration thaum nres / tso tawm
Fault Phenomenon: Sib tsoo, squealing, los yog clunking suab; pom tseeb kev co ntawm lub cev nres thaum ua haujlwm.
Keeb kwm:
Loose fasteners: Mounting bolts lossis txuas pins yog xoob (M16 bolts xoob los ntawm qhov ntsuas 80-100 N·m torque).
Lining/wheel deformation: Uneven lining wear or wheel end face runout >0.1 hli.
Caij nplooj ntoos hlav resonance: Disc springs resonate nrog nres lub cev thaum compression / tso tawm.
Distinguishing Feature: Lub suab nrov ploj tom qab zawm bolts los yog hloov lub hauv ob sab phlu; Lub suab nrov resonance yog nrog los ntawm ib qho kev vibration tshwj xeeb.
6. Phau ntawv tso tawm tsis ua haujlwm (Kev saib xyuas-Txog)
Fault Phenomenon: Lub tes tsho tso tawm tsis tuaj yeem rub, lossis rub tsis tau tab sis tsis tuaj yeem nqa lub npoo; lub nres tsis tuaj yeem tso tawm rau kev saib xyuas thaum lub hwj chim tawm.
Keeb kwm:
Qws jamming: xeb ntawm lub pas nrig pivot lossis txuas pas nrig dabtsi yog khoov.
Mechanical resistance: Disc springs yog daig, los yog sib npaug -retraction mechanism raug kaw.
Distinguishing Feature: Lub zog xav tias tawv thaum rub; tsis muaj qhov pom tseeb txav ntawm hauv ob sab phlu thaum lub zog ua haujlwm.
7. Electromagnet Holding Failure
Fault Phenomenon: Lub nres tuaj yeem tso tawm los ntawm lub cev muaj zog tab sis tsis tuaj yeem tuav lub xeev tso tawm; lub cev muaj zog restarts nquag los them rau lub zog tuav.
Keeb kwm:
Electromagnet coil burnout los yog tsis txaus tuav tam sim no.
Cov huab cua sib txawv ntawm cov electromagnet armature thiab cov tub ntxhais yog loj heev (ntau tshaj qhov ntsuas 0.2-0.5 hli).
Distinguishing Feature: Lub nres tso tawm tam sim tom qab lub cev muaj zog nres; electromagnet tsis muaj lub zog nqus thaum lub zog.
Ntsiab Lus
Feem ntau qhov txhaum ntawm DLZ100 series muaj feem xyuam rau nwshluav taws xob-mechanical integrated design(piv txwv li, lub cev muaj zog-electromagnet hloov tsis ua haujlwm, txwv kev hloov pauv tsis ua haujlwm).
Rau daim ntawv thov chaw nres nkoj ntug hiav txwv,corrosion- cuam tshuam txog kev ua txhaum(limit switch contact corrosion, fastener xeb) ntau zaus; Yuav tsum muaj kev tiv thaiv kev tiv thaiv- kev kho corrosion tsis tu ncua.
Tsis zoo li hydraulic brakes, nws tsis muaj roj to faults, ua rau nws tsim nyog rau tej thaj chaw rhiab heev.
