Kev Nyab Xeeb Kev Nyab Xeeb Rau Cov Hluav Taws Xob Ntawm Cov Nres Nres

Vim yog siv cov tshuab hluav taws xob fais fab, nws tseem ceeb heev rau kev tshuaj xyuas cov khoom siv hluav taws xob ntawm cov brakes.
(1) Nyob rau hauv kev ua haujlwm voltage, ua haujlwm lub tshuab traction raws li nws txoj haujlwm ua haujlwm, lub sijhawm thauj khoom, thiab lub voj voog. Thaum tus nres mus txog lub thermal stability, ntsuas qhov kub thiab txias ntawm tus brake coil. Txoj kev ntsuas tau txais cov qauv kev tiv thaiv tau teev tseg hauv Tshooj 8.6.2 ntawm GB 755-2008 "Kev Ntsuas thiab Kev Ua Haujlwm ntawm Kev Sib Tw Hluav Taws Xob" rau kev ntsuas thiab suav. Thaum siv B-theem rwb thaiv tsev, qhov kub siab ntawm lub kauj nres yuav tsum tsis pub tshaj 80K; Thaum siv Class F rwb thaiv tsev, qhov kub nce ntawm lub kauj nres yuav tsum tsis pub tshaj 105K. Rau cov brakes uas muaj qhov kub thiab txias tshaj 6 (TC), cov cim ceeb toom kom tiv thaiv kev kub nyhiab yuav tsum tau ntxiv.
(2) Kev ntsuas hluav taws xob tiv thaiv ntawm lub kauj nres yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm kev thov 1000V voltage ntawm cov khoom siv hluav taws xob thiab hauv av rau 1 feeb, thiab yuav tsum tsis muaj qhov tshwm sim tawg.
(3) Qhov tsawg kawg nkaus nqus hluav taws xob thiab qhov siab tshaj plaws tso tawm hluav taws xob ntawm lub nres solenoid yuav tsum tau ntsuas tom qab ntsuas qhov ntsuas kub ntawm qhov nres. GB/T 24478-2009 "Levator Traction Machine" qhia tias qhov tsawg kawg nkaus nqus hluav taws xob thiab qhov siab tshaj plaws tso tawm hluav taws xob ntawm lub nres solenoid yuav tsum qis dua 80% thiab 55% ntawm qhov ntsuas hluav taws xob, raws li.
(4) Cov brakes tshiab yog nruab nrog lub nres saib xyuas kev hloov. Thaum lub nres ua haujlwm txawv txav, qhov hloov pauv yuav qhib thiab lub elevator yuav nres rau kev tiv thaiv, muab kev lav phib xaub rau kev nyab xeeb thiab txhim khu kev qha ntawm lub nres. Tab sis tsis muaj cov txheej txheem tsim nyog, thiab kuv vam tias lawv yuav raug cuam tshuam los ntawm cov qauv yav tom ntej rau kev saib xyuas thiab tshuaj xyuas.
(5) Lwm qhov tseem ceeb ntawm qhov nres hluav taws xob yog qhov kev tswj xyuas ntawm lub kauj nres. Raws li cov qauv tsim nyog, nws tuaj yeem sau tau raws li hauv qab no: ① Thaum lub sijhawm ua haujlwm ib txwm muaj, tus nres yuav tsum nyob twj ywm hauv lub xeev tso tawm raws li lub zog txuas ntxiv. ② Txhawm rau txiav cov nres tam sim no, tsawg kawg yog ob qho khoom siv hluav taws xob ywj pheej yuav tsum tau siv, tsis hais seb cov khoom siv no puas koom nrog cov khoom siv hluav taws xob siv los txiav tawm tam sim no ntawm lub elevator tsav. ③ Lub npe hu ua kev ywj pheej hais txog qhov tsis muaj kev tswj hwm kev sib raug zoo ntawm ob tus contactors, uas yuav tsum tau tswj los ntawm ob qho kev ywj pheej thiab tsis tuaj yeem tswj tau los ntawm ib lub teeb liab thaum lub elevator nres, yog qhov tseem ceeb ntawm ib qho ntawm cov contactors tsis qhib. , lub elevator yuav tsum raug tiv thaiv kom tsis txhob khiav rov qab los ntawm qhov tseeb thaum cov kev taw qhia tom ntej ntawm kev ua haujlwm hloov thaum lub elevator lub cev muaj zog muaj peev xwm tsim hluav taws xob los ntawm lub tshuab hluav taws xob, nws yuav tsum tiv thaiv kev pub mis rau cov khoom siv hluav taws xob uas tswj cov nres. ⑥ Tom qab disconnect tus nres tso tawm Circuit Court, elevator yuav tsum tau braked zoo yam tsis muaj kev ncua ntxiv. Lub sij hawm nres ntawm lub nres yuav tsum tsis pub tshaj 0.5 vib nas this los tiv thaiv lub elevator ntawm rub rov qab los yog ntog. Lub sij hawm teb ntawm tus nres ua hauj lwm, uas kuj ua hauj lwm pab raws li ib tug braking caij rau lub nce ceev tiv thaiv ntaus ntawv ntawm lub elevator tsheb, yuav tsum ua raws li cov kev cai braking ntawm Tshooj 9.10.1 ntawm GB 7588-2003 Yog hais tias ib tug tiv tauj nyob rau hauv lub Circuit Court. yog daig, lwm tus contactor tseem tuaj yeem ntseeg tau qhov kev sib txuas ntawm lub nres nres kom tsis txhob ntog tuaj yeem saib xyuas qhov txhaum ntawm contactor tsis qhib los tiv thaiv lwm tus contactor tsis qhib thiab ua rau swb.
