Txoj Haujlwm Tshiab Ntawm Nres

Rau elevators, tus nres yog ob qho tib si ua haujlwm thiab cov cuab yeej kev nyab xeeb. Nrog rau kev txhim kho thev naus laus zis thiab kev txhim kho ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, ntau thiab ntau cov hlau nplaum ruaj khov synchronous gearless traction tshuab yuav hloov cov tsoos worm iav thiab cab traction tshuab. Yog li ntawd, tej zaum yuav tsis tas yuav nruab ib qho kev sib cais ntawm cov khoom siv tiv thaiv overspeed. Lub nres ntawm no hom ntawm cov hlau nplaum ruaj khov synchronous gearless traction tshuab (uas yuav tsum tau ua raws li hom kev sim) muaj kev tiv thaiv overspeed. Raws li qhov yuav tsum tau muaj ntawm Tshooj 9.10 ntawm GB 7588-2003, cov khoom siv tiv thaiv overspeed rau lub tsheb of elevator feem ntau yog tsim los ntawm ob ntu: kev soj ntsuam ceev thiab kev ua kom nrawm nrawm. Lub nres nres ntawm cov hlau nplaum ruaj khov synchronous gearless traction tshuab (tag nrho cov khoom siv brakes koom nrog hauv kev siv lub zog rau lub log tsheb lossis cov discs tau sib sau ua ke hauv ob qhov chaw, uas suav tias muaj kev rov ua dua sab hauv) yog siv los ua lub sijhawm ua kom qeeb lossis nres. lub elevator. Yog li ntawd, nyob rau hauv kev tshuaj xyuas, nws yog tsim nyog los xyuas seb lub nres yuav tsum muaj ib tug ntaus ntawv xeem daim ntawv pov thawj thiab qhia nrog upward overspeed tiv thaiv muaj nuj nqi, seb lub nres yog ncaj qha mus rau lub log traction, thiab seb puas yuav tsum tau siv cov khoom siv hluav taws xob los xyuas. kev ua haujlwm ib txwm muaj ntawm tus nres, tab sis nws tsis tas yuav tsum tau txuas nrog kev ruaj ntseg Circuit Court. Lub braking kev ua tau zoo ntawm nws cov kev tiv thaiv overspeed yuav tsum ua raws li cov cai ntawm Tshooj 9.10 ntawm GB 7588-2003.
