2-3T Cov Khau Taw Qhia

2-3T phau ntawv qhia khau yog cov khoom tseem ceeb hauv lub tshuab ua haujlwm of the elevator, siv los coj lub tsheb of elevator thiab counterweight raws cov kev taw qhia rails thaum txav ntsug. Lawv feem ntau haum rau elevators nrog lub peev xwm ntawm 2 mus rau 3 tons. Lawv lub luag haujlwm tseem ceeb yog los xyuas kom muaj kev ruaj ntseg ntawm lub elevator thaum lub sijhawm ua haujlwm, txo qis swaying ntawm lub tsheb, thiab ib txhij txo cov suab nrov, txhim kho kev nplij siab thiab kev nyab xeeb.

Raws li txoj cai, 2-3T phau ntawv qhia khau feem ntau muaj cov khau hauv qab, khau liner, hloov kho, thiab cov khoom sib txuas. Lub hauv paus khau, raws li lub ntsiab load- bearing lub cev, feem ntau yog ua los ntawm siab - lub zog cam khwb cia hlau los yog stamped steel phaj, muaj txaus rigidity los tiv thaiv lub lateral quab yuam ntawm lub elevator tsheb los yog counterweight; cov khau liner yog ib feem uas ncaj qha mus rau txoj kev tsheb ciav hlau, thiab feem ntau yog ua los ntawm hnav-resistant nylon, polyurethane, los yog cov ntaub ntawv sib xyaw. Nws tsis tshua muaj kev sib txhuam coefficient thiab muaj zog hnav tsis kam ua kom muaj kev sib txhuam tsis zoo nrog cov kev taw qhia kev tsheb nqaj hlau, ncua nws txoj kev pab cuam lub neej. Cov txheej txheem hloov kho (xws li kev hloov kho bolts lossis cov qauv caij nplooj ntoos hlav) tso cai rau kev kho kom zoo raws li cov lus qhia kev tsheb ciav hlau sib txawv lossis cov khau liner hnav, kom ntseeg tau tias qhov sib txawv tsim nyog (feem ntau yog 0.5-1mm) yog khaws cia ntawm cov khau qhia thiab cov kev taw qhia kev tsheb ciav hlau, tiv thaiv ntau qhov sib txawv uas ua rau lub tsheb swaying lossis tsis txaus.

Hais txog cov yam ntxwv ntawm kev ua tau zoo, 2-3T phau ntawv qhia khau yuav tsum ua tau raws li qhov yuav tsum tau ua kom muaj zog load-cov kabmob muaj peev xwm, kev ua haujlwm du, tsis tshua muaj suab nrov, thiab kev saib xyuas yooj yim. Rau 2-3T load peev xwm theem, cov qauv lub zog ntawm cov kev taw qhia khau yog xam los xyuas kom meej kev ruaj ntseg ntawm lub tsheb lub inertial quab yuam thiab lateral load thaum lub sij hawm elevator pib, braking, thiab ua hauj lwm; lub elastic tsim ntawm cov khau liner absorbs qee qhov kev vibrations, thiab ua ke nrog kev tswj qhov sib txawv, ua tiav kev ua haujlwm tsis tshua muaj suab nrov; qee cov qauv kuj siv cov khau khiab sib cais tsim, ua kom yooj yim rau kev hloov pauv tom qab hnav, txo cov nqi tu thiab kev poob qis.

Hais txog kev teeb tsa thiab kev sib raug zoo, 2-3T phau ntawv qhia khau yuav tsum tau ua kom zoo sib xws nrog cov ntsiab lus sib xws ntawm T-zoo li tus taw qhia rails (xws li T75, T89, T114, thiab lwm yam). Thaum lub sij hawm installation, lub verticality thiab kab rov tav yuav tsum tau nruj me ntsis hloov raws li lub elevator installation specifications, kom ntseeg tau tias symmetrical faib ntawm sab laug thiab txoj cai qhia khau kom tsis txhob eccentric loading los yog txawv txav vim installation tsis raug. Tsis tas li ntawd, kev kho cov txheej txheem ntawm cov kev taw qhia khau (xws li bolted kev sib txuas los yog vuam) yuav tsum tau txiav txim siab raws li cov yam ntxwv ntawm lub tsheb of elevator lossis counterweight thav duab, ua kom muaj kev ruaj ntseg thiab txhim khu kev qha kev sib txuas kom tsis txhob xoob lossis detachment thaum lub sijhawm ua haujlwm.

Hauv kev siv cov tswv yim, 2-3T phau ntawv qhia khau yog dav siv hauv nruab nrab-load elevators, xws li thaj chaw elevator, chaw ua haujlwm of elevator, thiab cov khoom thauj me me. Thaum siv txhua hnub, hnav cov khau hauv ob sab phlu, kev ua haujlwm ntawm kev hloov kho, thiab qhov nruj ntawm qhov sib txuas yuav tsum tau kuaj xyuas tsis tu ncua. Thaum hnav cov khau hauv ob sab phlu mus txog qhov tsim txwv (feem ntau yog thaum hnav qhov tob tshaj 1/3 ntawm qhov qub thickness) los yog thaum tawg los yog deformation tshwm sim, nws yuav tsum tau hloov tam sim ntawd kom muaj kev nyab xeeb thiab ruaj khov ua haujlwm ntawm lub elevator. Nws tsim thiab kev tsim khoom yuav tsum ua raws li cov qauv hauv lub tebchaws xws li GB / T 7025.1-2021 "Lub ntsiab Parameters thiab Hom thiab Dimensions of Elevator Cars, Shafts, thiab Machine Rooms Part 1: Class I, II, III, thiab VI Elevators," kom ntseeg tau cov khoom zoo thiab kev nyab xeeb.
