Paub qhov zoo thiab qhov tsis zoo ntawm cov roj hmab expansion pob qij txha,
1. txheeb xyuas thiab txheeb xyuas cov xim ntawm cov roj hmab expansion pob qij txha.Zoo dua insulating roj hmab expansion pob qij txha muaj ci xim, sib sib zog nqus xim purity thiab du nto.Nyob rau hauv sib piv, cov yeeb yaj duab theem nrab yog npub nyob rau hauv cov xim, nrog ib tug ntxhib nto thiab cua npuas.Yuav tsum tsis muaj teeb meem irregularities nyob rau sab sauv thiab sab saum toj ntawm lub insulating roj hmab expansion sib koom ua ke.Kev puas tsuaj tsis sib xws, qhov me me, tawg, hauv zos bulges, txiav, suav nrog, creases, qhov khoob, concave thiab convex ripples, casting marks, thiab lwm yam yog tag nrho cov yam tsis zoo uas ua rau tsis zoo thiab ua rau lub ntsej muag du.Harmless inhomogeneity yog hais txog qhov inhomogeneity saum npoo tsim thaum lub sij hawm tsim khoom.
2. Cov ntxhiab ntawm cov roj hmab expansion sib koom ua ke tau tsim nyog.Ib qho zoo dua roj hmab expansion sib koom ua ke tuaj yeem hnov qab nrog lub qhov ntswg.Nws muaj ntxhiab tsw me ntsis, tab sis nws tuaj yeem tawg mus rau lub sijhawm luv luv.Txhua yam khoom siv roj hmab yuav muaj ntxhiab tsw tshwj xeeb.Ntawm qhov tsis sib xws, cov ntawv tsis zoo ntawm cov roj hmab insulating yuav tsim cov ntxhiab tsw ntxhiab, thiab yog tias siv rau lub sijhawm ntev, yog tias koj nyob hauv qhov chaw no ob peb feeb, koj yuav muaj cov tsos mob kiv taub hau.
Peb: Kev ua haujlwm ntawm cov roj hmab expansion sib koom ua ke tuaj yeem ncaj qha quav cov khoom.Lub zoo roj hmab expansion sib koom ua ke tsis muaj cov cim ntawm folding.Ntawm qhov tsis sib xws, cov ntaub ntawv roj hmab tsis zoo yuav raug tawg.Ntau tshaj 5 cov ntsiab lus sib txawv yuav tsum tau xaiv los xaiv rau kev ntsuas tuab thiab tshuaj xyuas tag nrho cov ntawv roj hmab.Nws tuaj yeem ntsuas nrog ib txhiab lub plawv qia lossis qhov tseeb sib npaug.Qhov tseeb ntawm lub caliper yuav tsum tsis pub dhau 0.02 hli, txoj kab uas hla ntawm lub caliper yuav tsum yog 6 hli, txoj kab uas hla ntawm lub tiaj presser ko taw yuav tsum yog 3.17 ± 0.25 hli, thiab presser ko taw yuav tsum muaj peev xwm tiv taus lub siab (0.83 ± 0.03). ).Lub insulating gasket yuav tsum tau muab tso rau hauv tiaj tus, kom du los ntawm caliper mus rau caliper.
Plaub, qhov hnyav ntawm cov roj hmab pob qij txha nrog cov diameters.Feem ntau, qhov zoo ntawm cov khoom siv roj hmab hnyav zoo dua.Qhov no yog vim hais tias nws tau hais meej meej tias cov roj hmab txheej ntawm cov roj hmab cov pob qij txha yuav tsum ncav cuag ib tus qauv, tab sis qee qhov kev lag luam txiav cov fab thiab zais cov roj hmab cov khaubncaws sab nraud povtseg., mus dag cov neeg siv khoom.Qhov thib ob yog nias lub npoo ntawm cov roj hmab sib koom tes nrog cov ntiv tes.Yog tias qee qhov elastic deformation tuaj yeem ua tiav, nws tuaj yeem pom tau tias elastic deformation kev ua tau zoo ntawm cov roj hmab sib koom tsis muaj kev cuam tshuam ntau.
