Hauv kev lag luam machinery sector, cranes yog hom tseem ceeb ntawm kev nqa nqa hnyav.Cov tshuab loj no tso siab rau ntau yam khoom siv los xyuas kom muaj kev nyab xeeb thiab ua haujlwm tau zoo, thiab ib qho tseem ceeb ntawm cov khoom siv yog qhovelectromagnetic nresqhov system.Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv cov hauv paus ntsiab lus ntawm kev ua hauj lwm thiab kev hloov kho ntawm electromagnetic brakes nyob rau hauv cranes, elucidating yuav ua li cas lawv pab txhawb rau lub lag luam du ntawm cov haib lifting pab kiag li lawm.
Qhov tseem ceeb ntawm Electromagnetic Brakes hauv Cranes:
Cranes yog tsim los tswj cov khoom hnyav, ua rau lawv lub zog nres yog qhov tseem ceeb ntawm kev nyab xeeb.Electromagnetic brakesua lub luag haujlwm tseem ceeb hauv kev tswj kev nres ntawm cranes.Kev nkag siab txog lawv cov hauv paus ntsiab lus thiab kev hloov kho kom raug yog qhov tseem ceeb rau kev tswj xyuas kev nyab xeeb, kev ua haujlwm zoo, thiab tiv thaiv kev poob qis.
Cov Cai Ua Haujlwm ntawmCrane Electromagnetic Brakes:
Thaum lub sij hawm statorelectromagnetic nresyog de-energized, springs exert force on armature, clamping kev sib txhuam disc sib dhos ntawm lub armature thiab flange, tsim braking torque.Lub sijhawm no, muaj qhov sib txawv "Z" ntawm armature thiab stator.
Thaum nws tsim nyog los tso tus nres, lub hwj huam ncaj qha tam sim no yuav tsum txuas nrog lub stator, thiab lub armature yuav txav mus rau stator vim yog lub zog hluav taws xob.Raws li lub armature txav, nws compresses lub springs, tso cov kev sib txhuam disc sib dhos thiab disengaging tus nres.
Electromagnetic brakes rau cranes
Kev kho ntawm Crane Brake System:
Clearance Kho: Thaum tus nres tso tawm, ib tug me me clearance yuav tsum tau khaws cia nyob rau hauv lub armature phaj thiab lub nres nres kom ntseeg tau tias dawb txav.Feem ntau, qhov kev tshem tawm no poob rau hauv thaj tsam ntawm 0.25 txog 0.45 millimeters.Kev teeb tsa qhov kev tshem tawm no yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm tus nres.
Torque Calibration: Los xyuas kom meej tias tus nres tuaj yeem nres qhov kev nyab xeebcrane's load, tus nres yuav tsum tau calibrated los muab qhov yuav tsum tau braking torque.Qhov kev hloov kho no nyob ntawm lub crane lub peev xwm thiab kev ua haujlwm.
Hnav Saib Xyuas: Tsis tu ncua tshuaj xyuas cov khoom nres rau cov cim ntawm kev hnav.
Kev ntsuas kub:Electromagnetic brakesua kom sov thaum ua haujlwm.Kev saib xyuas thiab tswj kev ua haujlwm kub yog qhov tseem ceeb los tiv thaiv overheating, uas tuaj yeem ua rau txo qis kev ua haujlwm thiab hnav tsis taus.
Kev tu ncua sij hawm: Kev saib xyuas tsis tu ncua, suav nrog kev tu thiab lubricating cov khoom sib tsoo, yog qhov tseem ceeb rau kev ua haujlwm zoo thiab txhim khu kev qha.

Electromagnetic nressystems yog ib qho tseem ceeb nyob rau hauv lub realm ntawm crane ua hauj lwm, lub luag hauj lwm rau kev nyab xeeb tuav loj loads.Nkag siab txog lawv cov qauv kev ua haujlwm thiab siv cov txheej txheem hloov kho kom raug yog qhov tseem ceeb raucranecov neeg ua haujlwm, pab pawg saib xyuas, thiab cov neeg ua haujlwm nyab xeeb.Los ntawm kev ua raws li cov hauv paus ntsiab lus no, peb tuaj yeem ua kom ntseeg tau tias cranes nruab nrogelectromagnetic nrestxuas ntxiv ua tus pab txhim khu kev qha hauv kev lag luam, txhawb kev nyab xeeb thiab kev ua haujlwm zoo hauv kev ua haujlwm nqa hnyav.
