Stainless hlau hlau hose yog ib qho tseem ceeb hauv kev sib txuas cov kav dej ntawm cov khoom siv niaj hnub no. Thaum cov yeeb nkab raug rau kev ua haujlwm siab tshaj qhov taw tes nws tuaj yeem txhawb nqa, nws tuaj yeem khoov tam sim ntawd zoo li cov tswv cuab muaj zog lossis lub cylindrical coil caij nplooj ntoos hlav. Qhov kev ntseeg siab ntawm cov kab sib luag zoo li ploj vim yog folding. Feem ntau ntawm kev puas tsuaj rau cov khoom tsim los ntawm engineering tej yaam num kuj yog vim li no.
Txawm hais tias stainless hlau hlau hoses, elastic huab cua siab ntsaws ruaj ruaj, telescopic yeeb nkab expansion pob qij txha, los yog hlau hoses, muaj xws li cov teeb meem. Hauv lwm lo lus, lub peev xwm ntawm cov khoom lag luam los tiv thaiv cov roj siab feem ntau nyob hauv nws txoj kev ntseeg siab. Txhawm rau kawm txog kev ntseeg siab ntawm cov khoom, lub nra tuaj yeem ntsuas tau siv Euler siab bar kev sib raug zoo:
1. Vim tsis txaus ua raws li corrugation loj, stainless hlau hlau hose thav duab thickness, thiab lwm yam., lub axis ntawm cov hlau hose feem ntau deviates los ntawm nws thawj axis ntawm symmetry. Nyob rau hauv lwm yam lus, qhov tseeb, lub axis ntawm cov khoom muaj ib tug me me ib nrab-kawg curvature. Rau cov hlau hoses, qhov tsis sib xws ntawm lub tes tsho mesh thiab qhov tsis sib xws ntawm lub zog ntawm txhua khub kuj txo cov peev txheej ntawm cov yeeb nkab corrugated.
2. Vim hais tias tus nqi bending stiffness nyob rau hauv lub siab load formula ntawm stainless hlau hlau hose yog txiav txim raws li nyob rau hauv cov dej yoj (trough) semicircle ntawm cov khoom raws li nruj kev twb kev txuas taw tes ntawm lub diaphragm, stainless hlau hlau hose nws tus kheej yog siab tshaj dabtsi yog khoov txhav. tus nqi.
