1. Kev txhais ntawm of the elevator speed limiters
Lub elevator speed limiter yog cov cuab yeej siv tshuab uas ua haujlwm los txwv kev ceev ntawm lub tsheb of elevator lossis counterweight, tiv thaiv kev sib tsoo los ntawm kev siv ntau dhau. Nws feem ntau yog siv ua ke nrog kev ruaj ntseg nres; Thaum kuaj pom qhov mob hnyav dhau lawm, qhov kev txwv nrawm nrawm nrawm nrawm, ua rau muaj kev nyab xeeb nres kom nres lub tsheb thiab xyuas kom muaj kev nyab xeeb ntawm cov neeg caij tsheb.
2. Txoj Cai Ua Haujlwm
Cov kev txwv ceev yog txuas nrog lub tsheb of elevator ntawm lub steel cable, tsim ib lub voj kaw nyob ib ncig ntawm lub pulley thiab ib qho expansion pulley nyob rau hauv lub qhov. Thaum lub tsheb ceev tshaj qhov pib ua ntej, qhov kev txwv ceev tau qhib los ntawm kev sib txuas ntawm cov khoom siv txuas nrog lub nres kev nyab xeeb, uas clamps rau ntawm lub steel cable, sai sai nres lub tsheb. Cov txheej txheem no tshwm sim tam sim ntawd kom ntseeg tau tias yog tias muaj kev ua haujlwm tsis zoo, lub elevator tuaj yeem nres tam sim ntawd.
3. Hom kev txwv ceev
Of elevator speed limiters tuaj yeem faib ua ntau hom:
Mechanical Speed Limiters: Cov no siv lub cev lub cev los ntsuas qhov nrawm, xws li cov ntsiab lus quab yuam centrifugal.
Electromagnetic Speed Limiters: Cov no siv cov teeb liab hluav taws xob los tswj cov khoom siv clamping thiab pib braking thaum overspeed tshwm sim.
Bidirectional Speed Limiters: Muaj peev xwm saib xyuas ob qho tib si nce thiab nqis nrawm ntawm lub tsheb, muab kev tiv thaiv ntau dua.
4. Cov qauv kev lag luam thiab kev sim
Raws li lub teb chaws tus qauv GB7588-2003, elevator yuav tsum tau nruab nrog cov txwv ceev thiab raug kuaj thiab ntsuas tsis tu ncua. Rau cov neeg muaj hnub nyoog qis dua 15 xyoos, kev kuaj xyuas txhua xyoo ntawm lawv qhov kev ua haujlwm nrawm yuav tsum ua kom ntseeg tau tias kev ua tau zoo raws li cov qauv kev nyab xeeb. Tsis tas li ntawd, cov elevator tshiab tau raug yuam kom suav nrog cov khoom siv tiv thaiv kev tiv thaiv overspeed los daws cov kev pheej hmoo overspeed thaum lub tsheb khoob lossis me me.
5. Kev ua lag luam xwm txheej thiab yav tom ntej Trends
Nrog kev loj hlob sai hauv nroog thiab kev nce hauv cov tsev siab, kev thov rau cov elevator tseem nce ntxiv. Nyob rau hauv xyoo tas los no, kev lag luam of the elevator tau tsiv mus raudigitalizationthiabcov tshuab ntse, nrog cov kev soj ntsuam xyuas ntse dhau los ua tus qauv tshiab uas yuav txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm cov txwv ceev. Tsis tas li ntawd, muaj ntau qhov kev thov rau retrofitting elevators nyob rau hauv cov tsev laus, nthuav tawm cov kev lag luam tshiab rau kev lag luam ceev limiter.
Xaus
Raws li cov cuab yeej tseem ceeb rau kev ua kom muaj kev nyab xeeb ntawm cov neeg caij tsheb, lub elevator ceev txwv tau txuas nrog rau kev nce qib hauv kev siv thev naus laus zis thiab kev txhim kho hauv cov qauv kev lag luam. Nrog rau kev hloov pauv kev lag luam xav tau thiab kev ua haujlwm thev naus laus zis, kev txwv ceev yav tom ntej yuav dhau los ua kev txawj ntse thiab ua haujlwm tau zoo, muab kev tiv thaiv zoo rau kev ua haujlwm of the elevator.
