Hydraulic of Elevator
Of elevators yog cov khoom siv thauj mus los ntsug tseem ceeb hauv cov tsev niaj hnub, dav siv hauv cov tsev nyob, cov tsev lag luam, cov chaw tsim khoom, thiab lwm yam xwm txheej. Thaum xaiv lub elevator rau lub tsev, ntau tus neeg tsis meej pem txoghydraulic of elevatorthiabtraction of elevator-ob hom of the most mainstream of the elevator. Kab lus no yuav qhia meej txog qhov sib txawv ntawm hydraulic elevators thiab traction elevators, nrog rau lawv cov qauv tseem ceeb, cov qauv kev ua haujlwm, qhov zoo, qhov tsis zoo, thiab cov xwm txheej siv tau, pab koj txiav txim siab xaiv.
1. Hydraulic of Elevator: Txhais, Cov Qauv & Txoj Cai Ua Haujlwm
1.1 Lus Txhais & Cov Qauv Txheej Txheem
A hydraulic of elevatoryog hom of elevator uas siv lub zog hydraulic ua lub hauv paus tsav tsheb los thawb lub tsheb nce thiab nqis los ntawm kev sib kis ntawm cov roj hydraulic. Nws yog dav siv nyob rau hauv qis- cov tsev nce siab thiab hnyav-load scenarios, thiab nws cov qauv tseem ceeb yog tsim los ntawm plaub qhov tseem ceeb uas ua haujlwm ua ke kom ruaj khov ua haujlwm:
Hydraulic System: Xws li hydraulic twj tso kua mis, hydraulic lub tog raj kheej, hydraulic valve, roj tank, thiab roj pipeline, nws yog lub zog tseem ceeb ntawm lub elevator hydraulic. Lub twj tso kua mis hydraulic hloov tshuab hluav taws xob rau hauv lub zog hydraulic, thiab hydraulic valve tswj cov kev taw qhia ntws thiab siab ntawm cov roj hydraulic los thawb lub piston ntawm lub tog raj kheej hydraulic kom txav mus. Qhov no yog cov khoom tseem ceeb uas paub qhov txawv ntawm hydraulic elevators los ntawm traction elevators.
Tsheb System: Ua los ntawm lub cev lub tsheb thiab lub tsheb ncej, nws yog siv los nqa tib neeg lossis khoom. Hauv qab ntawm lub tsheb feem ntau txuas nrog lub piston pas nrig ntawm lub tog raj kheej hydraulic thiab yog ncaj qha tsav los ntawm tus pas nrig piston. Nws yooj yim hauv cov qauv thiab haum rau hnyav - thauj khoom thauj.
Kev taw qhia System: Nrog rau kev taw qhia kev tsheb ciav hlau thiab cov khau taw qhia, nws txwv txoj kev txav ntawm lub tsheb, ua kom lub tsheb nce thiab ntog ruaj khov raws txoj kab ntsug, thiab tsis txhob txav los yog sib txawv. Nws yog ib qho tseem ceeb los xyuas kom meej qhov kev nyab xeeb thiab kev nplij siab ntawm hydraulic elevator.
Tswj System: Tsim los ntawm lub txee tswj, kev ua haujlwm vaj huam sib luag, sensors, thiab lwm yam, nws yog lub luag haujlwm rau kev txais cov lus qhia (xws li kev xaiv hauv pem teb, qhov rooj qhib thiab kaw), tswj kev pib thiab nres ntawm hydraulic system, kev hloov siab, thiab paub txog kev ua haujlwm tsis siv neeg ntawm lub elevator hydraulic.
1.2 Txoj Cai Ua Haujlwm
Lub hauv paus ntsiab lus ntawm kev ua haujlwmhydraulic of elevatoryog raws li Pascal txoj cai, uas tau hais tias thaum lub siab kis mus rau hauv lub thawv kaw, lub siab ntawm txhua qhov sib npaug. Cov txheej txheem ua haujlwm tshwj xeeb yog raws li hauv qab no, uas yog ib qho ntawm cov ntsiab lus tseem ceeb rau cov neeg siv kom nkag siab txog hydraulic elevator:
Cov txheej txheem Ascent: Tom qab tau txais kev qhia nce toj, lub txee tswj pib lub twj tso kua mis hydraulic. Lub twj tso kua mis hydraulic pressurizes cov roj hydraulic hauv cov roj tank thiab xa mus rau lub tog raj kheej hydraulic los ntawm hydraulic valve. Lub siab - hydraulic roj thawb lub piston nce siab, thiab lub piston tsav lub tsheb ncej thiab lub tsheb nce synchronously. Thaum nws mus txog hauv pem teb, lub twj tso kua mis hydraulic nres ua haujlwm, hydraulic valve kaw, thiab lub tsheb tseem nyob ruaj khov.
Txheej txheem qhovntsej thiaj tsis mob: Tom qab tau txais kev qhia qhovntsej thiaj tsis mob, lub hydraulic valve qhib. Raws li qhov kev txiav txim ntawm lub tsheb tus kheej qhov hnyav thiab thauj khoom, cov roj hydraulic hauv lub tog raj kheej hydraulic maj mam ntws rov qab mus rau lub tank roj. Lub piston txav mus rau pem hauv ntej nrog lub backflow ntawm hydraulic roj, tsav lub tsheb kom nqis mus ruaj khov. Thaum nws ncav cuag lub hom phiaj hauv pem teb, hydraulic valve kaw kom tiav qhov nqis tes ua.
1.3 Pros & Cons ntawm Hydraulic Elevators
1.3.1 Qhov zoo
Muaj zog Load-Bearing Capacity: Cov yam ntxwv ntawm lub siab kis tau tus mob ntawm hydraulic system ua rau nws haum rau hnyav-load scenarios. Qhov kev thauj khoom ntau yog 1000kg-10000kg, uas yog siv dav hauvindustrial freight elevators, warehouse elevators, thiab lwm yam hnyav -load elevator daim ntawv thov. Qhov no yog ib qho ntawm qhov zoo tshaj plaws ntawm hydraulic elevators piv rau traction elevators.
Ua haujlwm du thiab ntsiag to: Cov nyhuv buffering ntawm cov roj hydraulic tuaj yeem txo kev vibration thiab suab nrov thaum lub sijhawm nqa cov txheej txheem nqa, muab kev caij tsheb zoo dua. Nws yog tshwj xeeb tshaj yog haum rau scenarios rhiab rau lub suab nrov, xws li cov tsev nyob thiab cov tsev ua haujlwm me me.
Cov qauv yooj yim & Kho yooj yim: Piv nrog traction elevators, hydraulic elevator muaj ib tug yooj yim mechanical qauv. Cov khoom tseem ceeb (hydraulic twj tso kua mis, hydraulic lub tog raj kheej) muaj qhov tsis ua haujlwm tsawg. Kev saib xyuas txhua hnub feem ntau tsom rau kev hloov cov roj hydraulic thiab kev tshuaj xyuas cov ntsaws ruaj ruaj, nrog rau cov nqi tu qis. Qhov no yog qhov txiaj ntsig tseem ceeb rau cov neeg siv uas nrhiav tus nqi- ua tau zoo.
Tsis xav tau chav tshuab: Feem ntau cov elevator hydraulic tuaj yeem siv lub tshuab-chav-tsim tsawg dua, tsuas yog xav tau lub chaw nres tsheb hydraulic me me ntawm ib sab ntawm lub hoistway, txuag lub tsev. Nws yog qhov tsim nyog rau cov tsev qis- nce siab (tsawg dua lossis sib npaug li 6 plag tsev) lossis cov xwm txheej uas tsis muaj chaw siv tshuab, xws li villas thiab cov chaw tsim khoom me.
1.3.2 Qhov tsis zoo
Slowing Ceev: Txwv los ntawm tus nqi ntws ntawm cov roj hydraulic, qhov ceev ntawm hydraulic elevator feem ntau yog 0.1m / s -0.5m / s, uas yog qis dua li ntawm traction elevators. Nws tsis haum rau cov tsev siab siab uas xav tau kev thauj mus los ceev ceev.
Kev siv hluav taws xob siab: Lub twj tso kua mis hydraulic yuav tsum tau siv hluav taws xob tsis tu ncua thaum lub sijhawm ua haujlwm, thiab muaj lub zog poob hauv cov txheej txheem ntawm cov roj hydraulic. Lub sij hawm ntev - kev siv hluav taws xob ntau dua li ntawm traction of elevator, uas tsis tsim nyog rau kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig.
Risk ntawm Leakage: Yog tias cov ntsaws ruaj ruaj ntawm lub hnub nyoog hydraulic los yog puas lawm, hydraulic roj to yuav tshwm sim, uas tsis tsuas yog cuam tshuam rau kev ua haujlwm ntawm lub elevator tab sis kuj tuaj yeem ua paug rau ib puag ncig. Kev tshuaj xyuas tsis tu ncua ntawm kev ua haujlwm sealing yog yuav tsum tau, uas ua rau nce tus nqi tshuaj xyuas txhua hnub.
Qhov siab txwv: Vim qhov txwv ntev ntawm lub tog raj kheej hydraulic, qhov siab tshaj plaws nqa qhov siab ntawm hydraulic elevator feem ntau tsis tshaj 20 meters, uas tsuas yog tsim rau cov tsev qis - nce siab. Nws tsis tuaj yeem ua tau raws li cov kev xav tau ntawm siab - nce kev thauj mus los ntsug.
1.4 Siv tau Scenario ntawm Hydraulic Elevators
Hydraulic elevator feem ntau haum rau cov tsev qis - nce siab (1-6 pem teb) thiab cov xwm txheej hnyav. Cov ntawv thov uas muaj xws li:industrial Hoobkas freight of elevator, warehouse khoom thauj elevator, me me chaw ua hauj lwm tsev elevator,villa elevator (tsev elevator), tsev kho mob sundry elevator, thiab lwm yam. Nws yog thawj qhov kev xaiv rau qis-nce hnyav- thauj khoom of elevator xav tau, uas yog lub ntsiab lus tseem ceeb rau cov neeg siv tshawb nrhiav "tsawg-nce elevator xaiv".
