Kev sib piv ntawm Hydraulic Expansion Tube thiab Mechanical Expansion Tube Technology

Kev sib piv ntawm Hydraulic Expansion Tube thiab Mechanical Expansion Tube Technology

1: Mechanical thiab hydraulic expansion test data

1. Mechanical expansion tube: Lub raj xa hluav taws xob tau ua tiav raws li cov txheej txheem tiag tiag ntawm 300MW lub tshuab hluav taws xob siab, siv ob ntu ntawm cov pob qij txha expansion ua ntej thiab tom qab. Tag nrho qhov ntev ntawm qhov sib koom ua ke yog li 50r. Tom qab lub expansion tube yog nthuav, ib tug rub-out quab yuam kuaj thiab soj ntsuam anatomical yog nqa tawm.

2. Hydraulic tube expansion: Hydraulic raj expansion yog nqa tawm siv lub hydraulic tube expansion tshuab imported los ntawm lub teb chaws Yelemees. Kev sib txawv ntawm cov raj xa dej siab raug xaiv los nthuav dav tag nrho cov tuab ntawm lub raj phaj. Qhov ntev ntawm lub raj nthuav dav mus txog 350mm. Tom qab lub raj tau nthuav dav, kev sim rub tawm lub zog thiab kev tshuaj xyuas anatomical yog nqa tawm.

3. Raws li txoj kev xav ntawm cov yeeb nkab expansion, lub zog dav dav yuav tsum muaj cov yeeb nkab nthuav dav ntawm H=1-3%; Tus nqi nthuav dav uas yuav tsum tau ua yog H=0.1 txog 0.5%. Cov txheej txheem kev ua haujlwm rau 300MIV lub tshuab cua kub siab xav kom cov kav dej thiab lub phaj phaj qhov yuav tsum nruj, thiab tsuas yog qhov sib txawv ntawm cov kav dej thiab lub raj qhov yuav tsum tau tshem tawm tom qab nthuav dav. Tsis muaj qhov yuav tsum tau muaj rau kev nthuav dav, tab sis lub zog rub tawm tom qab nthuav dav yuav tsum ntau dua 5000N. Raws li kev paub dhau los, kev tshem tawm qhov sib txawv ntawm cov kav dej thiab lub raj lub qhov tuaj yeem ua tau raws li qhov yuav tsum tau ua yog tias qhov kev nthuav dav ntawm kev cuam tshuam ntawm cov kav dej thiab lub raj qhov yog ntau dua 0.05. Raws li qhov ntsuas no, tus nqi nthuav dav HO.5%.

B. Cov kauj ruam xeem:

1. Tus naj npawb ntawm lub raj qhov thiab cov raj hauv lawv qhov kev txiav txim, nrog rau ib qho kev nthuav dav raj thiab ib qho hydraulic expansion raj coj mus kuaj txhua.

2. Ntsuas lub puab lub cheeb ntawm lub raj phaj qhov, qhov tseeb qhov ntev ntawm lub puab thiab sab diameters ntawm lub raj, thiab khaws cov ntaub ntawv.

3. Ob qho piv txwv tau raug rau cov neeg kho tshuab expansion thiab hydraulic expansion, feem.

4. Ntsuas lub puab txoj kab uas hla ntawm cov yeeb nkab nthuav thiab xam cov expansion tus nqi.

5. Txiav ob qhov nthuav dav mus rau hauv ob qhov chaw los ntawm nruab nrab.
