Yuav Ua Li Cas Xaiv Lub Tsav Ntawm Metallurgical Choj Crane?

Yuav ua li cas xaiv lub cev muaj zog ntawm metallurgical choj crane?

Lifting thiab kev ua haujlwm ntawm lub10 tuj ib -girder craneyog inseparable los ntawm kev siv lub cev muaj zog.

Cov tsis muaj feem cuam tshuam ntawm ib qho -girder choj crane yuav tsum paub zoo, thiab raws li qhov no, ib qho kev xaiv ntxhib tuaj yeem ua rau kev ua tau zoo ntawm ib qho -girder choj crane rau lub cev muaj zog pib, braking, ceev tswj, load, torque, synchronization, thiab lwm yam.

Yog hais tias lub siab -voltage motor nrog tib lub zog raug xaiv, ntawm ib sab, ib qho - lub sij hawm peev yog nce, thiab cov efficiency yog li ntawm 2% qis dua qhov qis -voltage motor. Txawm li cas los xij, rau cov sijhawm uas cov kab hluav taws xob ntev ntev, daim phiaj muaj peev xwm raug txwv, qhov pib torque siab, lossis yuav tsum muaj peev xwm dhau, nws raug nquahu kom xaiv lub siab -voltage motor.

Xaiv cov yam ntxwv ntawm lub cev muaj zog: Cov yam ntxwv ntawm lub cev muaj zog yog txwv los ntawm cov yam ntxwv ntawm lub tshuab nws tsav. Cov yam ntxwv ntawm kev xaiv lub cev muaj zog yuav tsum sib haum nrog cov yam ntxwv ntawm lub nra uas nws tsav, kom ua tau raws li qhov yuav tsum tau ua ntawm kev txuag hluav taws xob thiab kev ua haujlwm nyab xeeb.

Thaum xaiv lub cev muaj zog, nws yuav tsum xav txog tus qauv, hom, ntsuas nrawm, ntsuas qhov ntsuas hluav taws xob, thiab ntsuas lub zog ntawm lub tshuab nqa nqa. Yog tias tsim nyog, cov chaw tsim khoom ntawm lub cev muaj zog, tom qab- kev muag khoom lav, kev pabcuam lub neej, thiab cov khoom tshwj xeeb xws li yam xws li kev tiv thaiv corrosion.

Lub cev muaj zog yog ib qho tseem ceeb ntawm kev tsav tsheb ntawm ib qho -girder choj crane. Feem ntau, nws siv lub qhov txhab rotor asynchronous lub cev muaj zog thiab lub tawb - hom asynchronous lub cev muaj zog.

Nyob rau hauv cov ntaub ntawv ntawm kev tsim txwv yuav tsum tau, lub siab tshaj plaws torque los yog xauv -rotor torque ntawm lub cev muaj zog yuav tsum tau raws li cov kev xav tau ntawm lub mechanism pib. Nyob rau hauv cov ntaub ntawv ntawm ua tau raws li qhov yuav tsum tau tsim, lub cev muaj zog yuav tsum tsis txhob overheat.

Cov yam ntxwv ua haujlwm ntawm 10 tuj ib leeg -girder choj crane yog kev ua haujlwm tsis tu ncua, nquag pib, nres (hluav taws xob lossis tshuab), thim rov qab, qee zaum overload, tseem ceeb vibration thiab poob siab, plua plav ib puag ncig ua haujlwm, thiab qee zaum hlau plua plav, qhov kub thiab txias sib txawv.

25 tuj hluav taws xob motors raumetallurgical choj cranesyog characterized los ntawm:
 

Nws cov txheej txheem ua haujlwm yog qhov nruab nrab ntawm lub sijhawm ua haujlwm lossis sib cuam tshuam lub sijhawm ua haujlwm nrog kev pib, uas muaj lub peev xwm loj dhau thiab lub zog ua haujlwm siab, thiab lub sijhawm rotor ntawm inertia yog me me, thiab qhov siab tshaj plaws kev nyab xeeb pub tshaj qhov ntau ntawm cov ntsuas ceev, zoo sealing.

Yog li ntawd, cov lus qhia tshwj xeeb tau teev tseg tias ib qho -girder choj crane yuav tsum siv ntau lub cev muaj zog rau lifting metallurgy.

10 tuj ib leeg -girder choj cranes siv dav dav lub tawb motors vim muaj lub cev muaj zog me me uas yuav tsum tau muaj nyob rau hauv qee qhov kev ua haujlwm. Kev saib xyuas yuav tsum tau them rau qhov pib torque, ntau yam ntawm qhov tsawg kawg nkaus torque thiab qhov siab tshaj plaws torque, thiab kev txiav txim siab yuav tsum tau muab rau thaum lub cev muaj zog pib, lub cev muaj zog qhov hluav taws xob poob qis, thiab lwm yam.
