Cov qauv tseem ceeb thiab qhov tseem ceeb ntawm of elevator ncej qhia kev tsheb ciav hlau kev teeb tsa. Hauv cov tsev niaj hnub no, elevators yog cov cuab yeej thauj mus los ntsug tsis tseem ceeb rau cov tsev siab siab, thiab lawv txoj kev nyab xeeb thiab kev ruaj ntseg yog qhov tseem ceeb tshwj xeeb. Tshwj xeeb tshaj yog lub ntiaj teb sab saum toj-ranked zoo heev elevator tuam txhab uas muag:
Otis(US)
ThyssenKrupp(Lub teb chaws Yelemees)
Kone(Finland)
Schindler(Switzerland)
Mitsubishi Electric Europe NV(Belgium)
Mitsubishi Heavy Industries Co., Ltd.(Nyiv)
ThyssenKrupp of Elevator AG(Duisburg)
DoppelmayrPawg (Austria)
Vestas(Danish)
Fujitec Co., Ltd.(Nyiv)
Txhua yam tseem ceeb heev rau kev nyab xeeb kev ua haujlwm ntawm elevator.
Lub installation zoo ntawm of elevator ncej ntsia ncaj qha rau kev khiav hauj lwm efficiency thiab kev nyab xeeb ntawm elevator. Yog li ntawd, kev nkag siab txog cov qauv kev teeb tsa ntawm of the elevator ncej rails yuav tsis tsuas yog pab cov neeg ua haujlwm tsim kho kom zoo dua qub, tab sis kuj tso cai rau cov pej xeem kom nkag siab zoo dua cov ntsiab lus tseem ceeb ntawm kev nyab xeeb of elevator.
Taug qab kev xaiv cov khoom siv: tus yuam sij hauv lub hauv paus
High-strength steel uas tau kub-los yog txias-dov yog feem ntau siv los ua elevator hoistway rails. Cov ntaub ntawv no yuav tsum muaj lub zog zoo, hnav tsis kam, thiab deformation kuj thiab ua raws li kev lag luam lossis cov qauv hauv tebchaws. Txoj haujlwm ua haujlwm ntawm lub tsheb of elevator yog "txhawb nqa" kom paub tseeb tias thaum lub sijhawm ua haujlwm ntev, tsis muaj hnav, deformations, lossis lwm yam teeb meem. Yog li ntawd, nws yog ib qho tseem ceeb kom paub tseeb tias cov ntaub ntawv zoo txaus siab rau tag nrho cov txheej txheem kev siv thaum xaiv cov ntaub ntawv taug qab. Ib qho kev siv cov khoom siv subpar tuaj yeem ua rau lub elevator txoj haujlwm muaj kev pheej hmoo rau cov teeb meem kev nyab xeeb.
Cov kev taw qhia kev tsheb ciav hlau yog qhov chaw thiab ruaj khov
Lub elevator hoistway txoj kab nruab nrab thiab qhov chaw teeb tsa ntawm cov lus qhia yuav tsum tau ua kom zoo kawg nkaus. Thaum lub sij hawm installation, ua tib zoo mloog rau txoj kab rov tav thiab ntsug ntsug. Lub elevator lub peev xwm ua haujlwm tau zoo yuav raug cuam tshuam los ntawm kev ua yuam kev me me. Piv txwv li, feem ntau muaj 1.5 mus rau 2 meters sib cais covqhia rail bracketlos ntawm phab ntsa hoistway. Txhawm rau kom cov tsheb ciav hlau tsis txav los yog vibrating thaum lub elevator ua haujlwm, txhua lub bracket yuav tsum ruaj khov thiab ruaj khov thaum ua haujlwm.expansion boltslos yog embedded pieces rau fastening.
Verticality of guide rails: "balancer" of elevator ua haujlwm
Lub verticality ntawm of the elevator guide rails ncaj qha cuam tshuam qhov smoothness ntawm of elevator ua haujlwm. Tus qauv qhia tias qhov kev sib txawv ntawm qhov kev sib txawv ntawm cov lus qhia yuav tsum tau tswj tsis pub dhau 1 hli ib meter, thiab tag nrho qhov siab yuav tsum tsis pub tshaj 0.5 mm / m ntawm of the elevator lifting height. Txhawm rau kom ntseeg tau qhov tseeb, laser calibrators lossis theodolite feem ntau yog siv rau kev kuaj pom tseeb thaum lub sijhawm teeb tsa. Txhua qhov kev sib txawv ntsug dhau qhov kev tso cai yuav ua rau lub tsheb of elevator co co thaum lub sijhawm ua haujlwm, cuam tshuam rau cov neeg caij tsheb caij tsheb.
Qhia kev tsheb ciav hlau sib txuas thiab kev sib txuas: cov ntsiab lus txiav txim siab txog kev nyab xeeb
Kev taw qhia kev tsheb ciav hlau yuav tsum tsis yog tsuas yog qhov tseeb verticality thiab kab rov tav, tab sis kuj ua haujlwm sib koom ua ke tseem ceeb sib npaug. Cov ntawv qhia tshwj xeeb rail txuas daim hlau yuav tsum tau siv rau cov pob qij txha ntawm cov kev taw qhia kev taw qhia kom paub tseeb tias cov pob qij txha yog tiaj thiab tsis muaj misalignment. Kev ua haujlwm tsis raug cai yuav ua rau muaj suab nrov lossis kev co thaum lub sijhawm ua haujlwm of the elevator, thiab tseem ua rau muaj teeb meem kev nyab xeeb loj dua. Tus txheej txheem teev tseg tias qhov sib txawv ntawm cov kev taw qhia kev tsheb ciav hlau yuav tsum tau tswj ntawm 0.1 thiab 0.5 hli kom hloov mus rau cov kev hloov pauv ntawm cov khoom siv thermal expansion thiab contraction kom ntseeg tau tias lub elevator ib txwm ua haujlwm zoo.
Lubrication thiab kev tiv thaiv ntawm kev taw qhia rails: ncua lub neej thiab txo kev txij nkawm
Thaum lub elevator ua haujlwm, cov kev taw qhia rail 'kev pabcuam lub neej tuaj yeem nce ntxiv los ntawm lubricating lawv raws li xav tau kom txo qis kev sib txhuam ntawm lawv thiab cov zawv zawg ntawm lub tsheb. Tsis tas li ntawd, kev tiv thaiv yuav tsum tau muab tso rau hauv qhov chaw thaum lub sij hawm tsim kho kom tsis txhob muaj plua plav, stains, thiab lwm yam kev puas tsuaj los ntawm kev nkag mus rau cov lus qhia kev tsheb ciav hlau. Ua kom lub elevator ua haujlwm zoo thiab txo qhov zaus thiab kev siv nyiaj ntawm kev saib xyuas tom ntej tuaj yeem ua tiav los ntawm kev tsim nyog lubrication thiab kev tiv thaiv.
Kev lees paub: qhov kawg kuaj xyuas kom muaj kev nyab xeeb ntawm kev ua haujlwm of elevator
Nws yog ib qho tsim nyog yuav tsum tau ua ntau qhov kev lees paub zoo tom qab kev teeb tsa ntawm cov lus qhia kev taw qhia txhawm rau lav tias lub elevator qhov kev ua tau zoo tag nrho ua tiav raws li lub teb chaws cov cai. Cov kev ntsuam xyuas no suav nrog kev ntsuas kev nyab xeeb, ntsuas kev thauj khoom, thiab kev ntsuas ceev. Los ntawm txoj kev kuaj no, cov teeb meem muaj peev xwm tuaj yeem txheeb xyuas thiab daws sai sai los lav qhov kev ruaj ntseg thiab kev nyab xeeb ntawm lub elevator thaum nws siv tiag tiag.
Pab neeg txhim kho kev tshaj lij thiab cov qauv siv nruj me ntsis tuaj yeem txhim kho kev ua haujlwm ntawm lub elevator tsis yog tsuas yog txhim kho kev ua haujlwm ntawm lub elevator, tab sis kuj muab cov neeg caij tsheb nrog kev nyab xeeb thiab xis dua caij tsheb. Yog li ntawd, xyuam xim rau cov qauv kev teeb tsa ntawm lub elevator qhia kev tsheb ciav hlau tsis yog tsuas yog lub luag haujlwm ntawm cov neeg ua haujlwm tsim kho, tab sis kuj yog ib qho kev txhawj xeeb ntawm cov neeg tsim khoom thiab cov neeg siv khoom.
