Ngaba ukhe wadibana nezi meko zilandelayo:
Kutheni iziphumo zovavanyo lwam lwesampulu zingaphumelelanga?
Idatha yeziphumo zovavanyo lwebhubhoratri iyaguquguquka?
Kufuneka ndenze ntoni ukuba ukuhluka kweziphumo zovavanyo kuchaphazela ukuhanjiswa kwemveliso?
Iziphumo zovavanyo lwam azihlangabezani neemfuno zomthengi. Indlela yokusombulula ngayo? ……
Ukusetyenziswa kwezinto ezibalulekileyo, ukuntsokotha ngakumbi, uvavanyo olongezelelweyo luhlala lufuneka ukuze kuqinisekiswe ukuqina kwesixhobo phantsi kweemeko zenkonzo kunye neemeko eziqhelekileyo. Ukuvelisa idatha yovavanyo oluphezulu ngumngeni omkhulu ngexesha lophuhliso lwezinto eziphathekayo, ukuyila kunye neemfuno zokulawula umgangatho.
Kulo mba, uchungechunge lwe-UP-2003 lomthwalo omkhulu we-elektronikiiinkqubo zovavanyo jikelelekunye noomatshini bokuvavanya ukudinwa, kudityaniswe nezinto ezidityanisiweyo ezidityanisiweyo kunye nezixhobo zokulinganisa ubunzima, banokuhlangabezana neemfuno ezahlukeneyo zovavanyo, kwaye bagxininise kule 3C ilandelayo (uCalibration, Control, Consistency) ingqikelelo yovavanyo lokuqinisekisa ukuba abathengi banokufumana idatha yovavanyo olukumgangatho ophezulu. idibana nemigangatho ebekiweyo kangangoko kunokwenzeka.
1.Ulungelelwaniso
Isixhobo sokulayishwa kwekhonkco lokudibanisa i-coaxiality:
Ii-axes ezahlukeneyo zekhonkco lokulayisha ngokulula zinokubangela ukungaphumeleli kwangaphambi kwexesha komfanekiso. Isiqinisekiso se-NADCAP sichaza ukuba ipesenti yokugoba eyamkelekileyo yovavanyo lwe-static yezinto ezidibeneyo ayikho ngaphezu kwe-8%. Indlela yokuqinisekisa kunye nokuqinisekisa ubumbano phantsi kweemeko ezahlukeneyo zovavanyo kubaluleke kakhulu.
Nyanzelisa ukulinganisa isivamvo:
Iimfuno zokuchaneka kwamandla kwizicelo ezahlukeneyo ziyahluka kakhulu. Ukuqinisekisa ukuchaneka kwamandla ngaphakathi koluhlu lokulinganisa kuyimfuneko yokuqinisekisa ukuchaneka kweziphumo zovavanyo.
I-Extensometer kunye ne-strain gauge calibration:
Isisombululo esilandelekayo somlinganiselo woxinzelelo oluncinci ukuqinisekisa umlinganiselo ongaguqukiyo woxinzelelo.
2. Ukulawula
Ipesenti yokugoba isampuli:
Imigangatho eyahlukeneyo ineemfuno ezingqongqo zolawulo lwepesenti yokugoba isampuli. Kubalulekile ngokulinganayo ukuqonda iimfuno ezisemgangathweni kunye nemisebenzi eyiyo.
Uvavanyo lolawulo lokusingqongileyo:
Kuvavanyo lwemathiriyeli edibeneyo kwiindawo eziphakamileyo nezisezantsi zobushushu, kukho iinkxalabo ezikhethekileyo ezifana nembuyekezo yeqondo lobushushu leegeyiji zoxinzelelo kunye nohlengahlengiso oluzenzekelayo lwezihlandlo zovavanyo, ezibaluleke kakhulu kwiziphumo zovavanyo kunye nokusebenza kovavanyo.
Ulawulo lwenkqubo yovavanyo:
Ulawulo lwenkqubo elungileyo alubandakanyi kuphela amanyathelo okusebenza kovavanyo, kodwa lukwabandakanya neerekhodi zotshintsho lwendlela yovavanyo kunye nezibalo zedatha yeziphumo.
3. Ukungqinelana
Ukungqinelana komfanekiso:
Indibano yesampulu phambi kovavanyo, i-fixture clamping pressure, ulawulo lwenkqubo yokulayisha kwangaphambili kunye namanye amanyathelo ahlukeneyo anempembelelo enkulu kwiziphumo zovavanyo.
Ukungqinelana komlinganiselo wovavanyo:
Umlinganiselo womlinganiselo kufuneka unike ingqwalaselo kwizinto ezifana nonyango lomphezulu wesampulu, indawo yomlinganiselo, ukuhanjiswa kokubala komlinganiselo, njl.njl., ukuze kuncitshiswe umahluko kwiziphumo.
Imo yokusilela ukungaguquguquki:
Ulawulo olusebenzayo lweendlela zokungaphumeleli kokwaphuka kwesampulu kunokuphucula kakhulu ukuqinisekiswa kwedatha.
Ezi nkcukacha zovavanyo zingentla zezinto ezihlanganisiweyo zinokunceda abasebenzisi abaninzi baqonde kwaye baqinisekise uzinzo kunye nokuthembeka kwedatha yovavanyo.
