Dab tsi yog hydraulic tube expanding tshuab?

Hydraulic expansion yeeb nkab tshuab yog cov khoom siv tshwj xeeb hydraulic expansion sib koom ua ke siv rau kev sib txuas nruj ntawm cov kav dej thiab cov ntawv raj hauv kev tsim cov khoom siv hluav taws xob, cov condensers, cov cua kub siab, thiab lwm yam khoom siv. Kev siv hydraulic expansion sib koom ua ke thev naus laus zis muaj qhov zoo ntawm cov nqi tsim khoom tsawg, lub zog siv zog, lub voj voog luv luv, thiab kev sib koom ua ke thiab txhim khu kev qha expansion sib koom ua ke zoo. Hydraulic expansion tube tshuab expansion sib koom ua ke thev naus laus zis tau siv dav hauv kev tsim cov khoom siv hluav taws xob hauv kev lag luam xws li petrochemicals, hluav taws xob, boilers, nuclear fais fab, tub yees, thiab lwm yam. Mechanical expansion sib koom ua ke yog ib txoj hauv kev nthuav dav cov kav dej siv cov pob bearings, uas muaj qhov zoo ntawm kev ua haujlwm yooj yim, kev ua haujlwm yooj yim thiab ceev, thiab cov nqi tsim khoom tsawg.

Raws li qhov tseeb tej yam kev mob xws li cov khoom ntawm lub raj phaj thiab cov geometric tsis ntawm expansion sib koom, lub expansion siab yuav xam tau siv cov nram qab no mis:

Cov residual contact stress ntawm cov yeeb nkab tuaj yeem xam los ntawm qhov sib npaug hauv qab no

Pc=(1-2C) Pi- σ Stlnkt (1)

Ntawm lawv, C=1/{kt2 (1-Ut)+1+Us+Et [(kt2-1)/Es (ks2-1)] [{ {7}}Us+ks2 (1+Us)]}

Lub tshuab hydraulic nthuav dav tuaj yeem ua cov pob qij txha nthuav dav ntawm 15-500mm tuab cov nplooj ntawv hauv ib qho mus rau tag nrho cov tuab. Vim tias kev tswj hwm digital tsis siv neeg, qhov kev nthuav dav tuaj yeem raug teeb tsa kom raug, kev ua haujlwm yog yooj yim, thiab qhov zoo ntawm kev nthuav dav kuj txhim khu kev qha. Nws tuaj yeem siv rau kev nthuav dav ntawm cov kav dej hauv cov yeeb nkab lossis cov kav dej welded, thiab nws cov kev siv zog tsawg, nrog kev ua haujlwm siab.

Nws cov kev xaiv yog txiav txim siab los ntawm lub puab kab uas hla, raj phaj thickness, expansion ntev, thiab expansion yam ntxwv ntawm lub tshav kub exchanger raj.
