Txoj Cai Ua Haujlwm ntawm Traction Tshuab

Lub traction tsav kev sib raug zoo ntawm lub traction of elevator yog qhia nyob rau hauv daim duab 1. Lub tshuab hluav taws xob, gearbox, nres, thiab lwm yam khoom siv nyob rau hauv lub tshuab chav tsev tsim lub tshuab traction, uas yog lub zog tsav rau lub traction tsav. Lub traction hlau hlua txuas nrog lub tsheb ntawm ib qho kawg thiab cov khoom hnyav ntawm qhov kawg ntawm lub log traction. Txhawm rau kom ntseeg tau tias lub tsheb of elevator thiab qhov hnyav hauv cov ncej khiav raws li cov lus qhia tsis muaj kev sib tsoo, lub log qhia tau muab tso rau ntawm lub tshuab traction kom cais lawv. Lub ntiajteb txawj nqus ntawm lub elevator lub tsheb thiab lub counterweight ntaus ntawv ua rau lub traction steel hlau hlua yuav compressed nyob rau hauv lub traction log zawj, tsim kev sib txhuam. Nyob rau hauv txoj kev no, kev sib hloov ntawm lub tshuab hluav taws xob tsav lub log traction tig, tsav cov hlua hlau hlau, thiab rub lub tsheb thiab qhov hnyav kom ua rau cov txheeb ze txav. Lub tsheb of elevator nce thiab qhov hnyav poob; Lub counterweight nce thiab lub tsheb of elevator nqis. Yog li ntawd, lub tsheb khiav rov qab thiab tawm mus raws cov kev taw qhia ntawm cov ncej, thiab lub elevator ua haujlwm ntsug tsheb thauj mus los.
Qhov kev sib txheeb ntawm lub tsheb of elevator thiab lub qhov hnyav yog ua tiav los ntawm kev sib txhuam quab yuam ntawm txoj hlua traction thiab lub log traction. Lub zog no hu ua lub zog rub lossis lub zog tsav tsheb. Lub load, txoj hauj lwm, thiab kev taw qhia ntawm lub tsheb of elevator yog txhua yam hloov thaum lub sijhawm ua haujlwm. Txhawm rau muab lub zog traction txaus rau lub elevator nyob rau ntau qhov xwm txheej, lub teb chaws tus qauv GB 7588-2003 "Kev Nyab Xeeb Code rau Kev Tsim Khoom thiab Kev Txhim Kho of Elevators" qhia tias:
Cov xwm txheej traction yuav tsum ua tau raws li: T1 / T2 Tsawg dua lossis sib npaug rau ef
Hauv cov qauv: T1 / T2- qhov sib piv ntawm qhov loj static nro rau qhov me me static nro ntawm cov hlua traction ntawm ob sab ntawm lub log tsheb thaum lub tsheb nqa 125% ntawm qhov ntsuas load nyob ntawm qhov chaw nres tsheb qis tshaj plaws thiab lub tsheb khoob yog nyob ntawm qhov chaw nres tsheb siab tshaj plaws.
C1- Coefficient ntsig txog acceleration, deceleration, thiab tshwj xeeb installation tej yam kev mob ntawm elevator, feem ntau hu ua dynamic coefficient
C2- Cov coefficient ntawm kev cuam tshuam ntawm kev hloov pauv ntawm tus ntoo khaub lig- ntu ntawm lub log traction zawj tshwm sim los ntawm kev hnav (rau ib nrab- voj voog lossis cov grooves: C2=1, rau V-shaped grooves: C2=1.2).
Nyob rau hauv ef , f yog qhov sib npaug ntawm kev sib txhuam coefficient ntawm txoj hlua traction hauv traction groove, thiab yog qhwv lub kaum sab xis ntawm txoj hlua traction ntawm lub log traction. EF yog hu ua traction coefficient. Nws txwv qhov piv ntawm T1 / T2, thiab qhov loj dua ef, qhov ntau dua qhov tso cai ntawm T1 / T2 thiab T1-T2, qhia tias lub elevator muaj peev xwm ntau dua. Yog li ntawd, lub traction coefficient ntawm lub elevator sawv cev rau nws lub peev xwm traction.
