Kev kos duab ntawm Pre-Stetching: Vim li cas Tswj Elongation yog qhov yuav tsum tau ua rau Precision Engineering
SOLITE TECHNICAL KNOWLEDGE SERIES
Tag nrho cov hlua hlau yog raug rau ob hom elongation: kev tsim kho thiab elastic. Rau cov ntawv thov precision xws li of the elevator traction lossis choj ncua kev kawm, kev tsim kho tsis raug cai yuav ua rau muaj kev puas tsuaj. Qhov no yog vim li cas cov txheej txheem ntawm Pre-stretching (los yog Pre-Tensioning) yog ib qho tseem ceeb ntawm kev tsim nqi.
Constructional Stretch:
Thaum ib txoj hlua tshiab tau muab tso rau hauv qhov load, tus kheej cov xov hlau thiab cov hlua 'tso' rau hauv lawv txoj haujlwm geometric kawg. Qhov no tuaj yeem ua rau qhov elongation mus tas li ntawm 0.5% mus rau 1.0%. Hauv kev ua haujlwm of the elevator, qhov kev ncab no tuaj yeem ua rau hauv pem teb - qib yuam kev lossis txawm tias muaj kev nyab xeeb hloov pauv. Hauv cov kav hlau txuas, nws tuaj yeem cuam tshuam qhov nro- qhov sib npaug ntawm tag nrho lub lawj.
SOLITE Ua Ntej-Txoj Kev Ua Haujlwm:
Peb qhov chaw tsim khoom siv hydraulic loj ua ntej - stretching txaj. Peb muab cov hlua ua tiav rau qhov rov ua dua ntawm qhov nro ntawm kwv yees li 40% mus rau 50% ntawm nws qhov tsawg kawg nkaus tawg Load (MBL). Cov txheej txheem no 'compacts' kev tsim kho, tshem tawm qhov pib ncab ua ntej txoj hlua puas tawm ntawm peb lub Hoobkas. Qhov tshwm sim yog 'Stable Strand' uas muab kev ua tau zoo los ntawm thawj hnub ntawm kev teeb tsa. Rau tus engineer, ua ntej -stretched ropes txhais tau tias tsawg downtime rau kev kho kho thiab qib siab dua ntawm qhov raug. Precision tsis yog xwm txheej; nws yog tsim.
