Rau cov haujlwm xws li cov tsev ua haujlwm, tsev so, tsev kho mob thiab cov tsev nyob,neeg nrog caij elevatortsis yog tsuas yog qhov tseem ceeb rau tib neeg kev txav mus los, tab sis kuj tseem muaj cov cuab yeej tseem ceeb uas cuam tshuam rau kev ua haujlwm ntawm kev ua haujlwm, cov qauv kev nyab xeeb thiab cov nqi tu tom ntej.
Txawm li cas los xij, cov neeg caij elevator tuaj nyob rau hauv ntau hom qauv nrog cov kev teeb tsa tsis yooj yim, thiab cov haujlwm sib txawv muaj cov kev xav tau sib txawv rau kev ceev, lub peev xwm thauj khoom, ncej qauv, kev tswj hwm thiab lub zog -txuag kev ua haujlwm. Yog li ntawd, txawm hais tias koj tab tom ua haujlwm ntawm qhov kev tsim kho tshiab lossis kho lub tsev uas twb muaj lawm, nws yog ib qho tseem ceeb kom nkag siab txog ntau hom of elevator thiab cov thev naus laus zis tshiab los xyuas kom meej cov qauv xaiv thiab kev ua haujlwm zoo.
Tsab ntawv xov xwm no yuav pab koj ua tiav cov kev daws teeb meem uas tsim nyog tshaj plaws ntawm cov neeg caij elevator los ntawm qhov kev xav ntawm qhov kev xav tau ntawm qhov project, kev tsis ua haujlwm, kev tswj hwm kev tswj hwm, cov nqi thiab kev saib xyuas.
Qhia meej txog cov yam ntxwv ntawm qhov project thiab daim ntawv thov scenarios
Cov neeg caij tsheb khiav txiav txim seb hom thiab ntau npaum li cas ntawm cov neeg caij elevator. Thawj kauj ruam hauv kev xaiv elevator yog txhawm rau txheeb xyuas cov neeg caij tsheb nrawm thiab siv zaus ntawm qhov project, uas yuav cuam tshuam ncaj qha rau kev tsim lub elevator ceev, lub peev xwm thauj khoom, kom muaj nuj nqis thiab pab pawg tswj hwm.
• Hom phiaj project:Commercial complexes thiab chaw ua hauj lwm cov tsev yuav tsum muaj elevator nrog kev khiav hauj lwm zaus thiab ceev ceev. Cov vaj tsev nyob ua qhov tseem ceeb ntawm kev nplij siab thiab kev siv hluav taws xob. Cov tsev kho mob xav tau cov elevator nrog lub peev xwm thauj khoom loj thiab kev nkag tau yooj yim.
• Peak neeg nrog caij:Puas muaj qhov pom tseeb thaum sawv ntxov thiab yav tsaus ntuj cov xuab moos nrawm lossis cov neeg caij tsheb muaj zog? Tus naj npawb ntawm cov neeg caij elevator tuaj yeem faib raws li cov tsev neeg lossis thaj chaw tsev, nrog rau kev xaiv ntawm ib qho kev tswj hwm lossis pab pawg tswj kev xa tawm.
• Pem teb qhov siab:Xaiv txoj kev hoisting raws li hauv pem teb qhov siab, nrog rau cov neeg caij tsheb traction elevators thiab hydraulic neeg nrog caij elevator.
• Kev txwv qhov chaw ntawm ncej:Tham elevator manufacturers rau kev pom tsis zoo ua ntej kev tsim kho yog tias qhov project tseem nyob rau theem tsim. Yog tias lub tsev tiav lawm, xa cov ntaub ntawv ntsuas mus rau engineers ntawm Fuji Elevator kom phim cov qauv elevator uas haum tshaj plaws.
Cov kev xav tau ua ntej dhau los tau lees paub, qhov ua tau zoo dua ncua sijhawm thiab cov nqi ntxiv los ntawm kev xaiv lub elevator tsis raug nyob rau theem tom ntej tuaj yeem zam tau.
Match Project Scale Raws li ceev thiab Load Capacity
Lub hauv paus ntawm qhov xav tau ntawm cov neeg caij tsheb tiag tiag, kev ceev thiab lub peev xwm thauj khoom yog cov cim tseem ceeb uas txiav txim siab tag nrho cov peev txheej thauj mus los thaum xaiv cov neeg caij elevator. Lawv yuav tsum raug txiav txim siab raws li kev ua haujlwm hauv tsev, tus naj npawb ntawm cov plag tsev thiab cov neeg caij tsheb khiav, es tsis txhob ua raws li cov lus qhia ntau dhau lossis cov nqi qis.
Txoj Kev Xaiv Ceev
• Cov vaj tse nyob:Nrog tsawg hauv pem teb thiab lub teeb neeg nrog caij. Load peev: 630-1000kg; Ceev: 1.0-1.5m / s. Xws li elevators muab kev nplij siab thiab kev siv nyiaj txiag, thiab yuav tsum muaj cov chaw nkag tau yooj yim.
• Cov Tsev Ua Haujlwm:Feem ntau nruab nrab-nce thiab siab- cov tsev nce siab nrog cov neeg caij tsheb hnyav thiab thauj khoom loj. Load peev: 1000-1600kg; Ceev: 2.0-3.0m / s. Lawv muaj kev ua haujlwm siab thiab kev ua haujlwm ntse nrog lub peev xwm muaj zog thaum lub sijhawm ua haujlwm siab.
• Tsev so & Cov Tsev Ua Lag Luam:Cov tsev nrog 6 mus rau 30 plag tsev. Load peev: 1250-1600kg; Ceev: 1.75-2.5m / s. Cov elevator no khiav ruaj khov thiab ntsiag to nrog siab -kawg kho kom zoo nkauj sab hauv.
• Super High-cov tsev nce siab:Cov plag tsev siab heev thiab hnyav cov neeg caij tsheb khiav, xav tau kev nqa nqa nrawm thiab ruaj khov. Load peev: Ntau tshaj lossis sib npaug rau 1600kg; Ceev: Ntau dua lossis sib npaug li 4.0m / s. Lawv ua haujlwm ntawm kev kub ceev nrog kev khiav haujlwm du thiab txais kev pabcuam zoned.
• Kev xam cov neeg caij tsheb khiav:Xam cov neeg caij tsheb nyob hauv 5 feeb ncov, ib qho - lub sijhawm mus ncig thiab lub sijhawm tos lub hom phiaj ( Tsawg dua lossis sib npaug li 30 vib nas this rau cov tsev ua haujlwm, Tsawg dua lossis sib npaug li 60 vib nas this rau cov tsev nyob).
• Formula:Tus naj npawb ntawm elevator=Cov neeg caij tsheb hauv 5 feeb ncov ÷ (Cov neeg caij tsheb ib lub elevator ib 5 feeb × 0.8)
Kev sib xyaw kom zoo ntawm kev ceev thiab lub peev xwm thauj khoom tuaj yeem txo lub sijhawm tos thiab txhim kho kev thauj mus los, thiab tiv thaiv kev ceeb toom tsis tu ncua, overload thiab tsis ruaj khov ntawm lub elevator thaum lub sijhawm ua haujlwm siab.
Xaiv cov qauv tsim nyog
Feem ntau cov neeg caij elevator qauv hom muaj xws li MR (nrog chav tshuab) thiab MRL (machine chav tsawg). Cov no tsis tsuas yog cuam tshuam rau txoj kev teeb tsa tab sis kuj txiav txim siab qhov yooj yim ntawm kev saib xyuas tom qab, kev siv hluav taws xob ua haujlwm, thiab cov nqi tsim tsev. Rau cov haujlwm sib txawv, txhua tus muaj nws tus kheej qhov zoo thiab yuav tsum muaj kev sib npaug raws li cov xwm txheej tshwj xeeb.
Tshuab Chav Less Elevators (MRL): Qhov Kev Xaiv Tseem Ceeb rau Cov Tsev Niaj Hnub No
