Ngaba wakha wadibana nezi meko zilandelayo:
Kutheni iziphumo zovavanyo lwam lwesampuli zingaphumelelanga?
Idatha yeziphumo zovavanyo lwelebhu iyatshintshatshintsha?
Ndingenza ntoni ukuba ukuguquguquka kweziphumo zovavanyo kuchaphazela ukuhanjiswa kwemveliso?
Iziphumo zovavanyo lwam azihlangabezani neemfuno zomthengi. Ndingazisombulula njani? ……
Kwizicelo ezibalulekileyo ezidityanisiweyo, uvavanyo olongezelelekileyo nolunzima ludla ngokufuneka ukuze kuchongwe ukuqina kwezinto phantsi kweemeko zenkonzo kunye neendawo eziqhelekileyo. Ukuvelisa idatha yovavanyo olusemgangathweni ngumceli mngeni omkhulu ngexesha lophuhliso lwezinto, uyilo kunye neemfuno zolawulo lomgangatho.
Ngokuphathelele oku, uthotho lwe-UP-2003 lwe-large-load electroniciinkqubo zovavanyo oluqhelekileyokunye noomatshini bokuvavanya ukudinwa, kunye nezixhobo zobuchwephesha zokulinganisa ubunzima, zinokuhlangabezana neemfuno ezahlukeneyo zovavanyo, kwaye zigxile kwingcamango elandelayo yovavanyo lwe-3C (Calibration, Control, Consistency) ukuqinisekisa ukuba abathengi banokufumana idatha yovavanyo esemgangathweni ehlangabezana neemfuno ezisemgangathweni kangangoko kunokwenzeka.
1. Ukulinganisa
Ukulinganiswa kwe-coaxiality ye-loading chain yezixhobo:
Ii-axes ezahlukeneyo zekhonkco lokulayisha zinokubangela ukusilela kwangaphambi kwexesha kwesampuli. Isiqinisekiso se-NADCAP sichaza ukuba ipesenti eyamkelekileyo yokugoba yovavanyo olungaguqukiyo lwezinto ezidityanisiweyo ayidluli kwi-8%. Indlela yokuqinisekisa nokuqinisekisa ukuba i-coaxiality phantsi kweemeko ezahlukeneyo zovavanyo ibaluleke kakhulu.
Ukulinganiswa kwenzwa yokunyanzela:
Iimfuneko zokuchaneka kwamandla kwiindlela ezahlukeneyo zokusetyenziswa zahlukile kakhulu. Ukuqinisekisa ukuchaneka kwamandla ngaphakathi koluhlu lokulinganisa kuyimfuneko yokuqinisekisa ukuchaneka kweziphumo zovavanyo.
Ukulinganiswa kwesandisi-mitha kunye ne-strain gauge:
Isisombululo sokulinganisa ubunzima obuncinci esilandelekayo ukuqinisekisa ukulinganiswa kobunzima obuhambelanayo.
2. Ulawulo
Ipesenti yokugoba kwesampulu:
Imigangatho eyahlukeneyo ineemfuno ezingqongqo zolawulo lwepesenti yokugoba kwesampulu. Kubaluleke ngokulinganayo ukuqonda iimfuno ezisemgangathweni kunye nemisebenzi yokwenyani.
Ulawulo lwendawo yovavanyo:
Uvavanyo lwezinto ezidityanisiweyo kwiindawo ezinobushushu obuphezulu nobuphantsi, kukho izinto ezithile ezixhalabisayo ezifana nokuhlawula ubushushu beegeyiji zoxinzelelo kunye nokulungiswa ngokuzenzekelayo kwemvamisa yovavanyo, ezibaluleke kakhulu kwiziphumo zovavanyo kunye nokusebenza kakuhle kovavanyo.
Ulawulo lwenkqubo yovavanyo:
Ulawulo olufanelekileyo lwenkqubo alubandakanyi nje kuphela amanyathelo okusebenza kovavanyo, kodwa lukwabandakanya neerekhodi zotshintsho lwendlela yovavanyo kunye nezibalo zedatha yeziphumo.
3. Ukungaguquguquki
Ukuhambelana kokuhlanganiswa kwemizekelo:
Ukuhlanganiswa kweesampuli ngaphambi kovavanyo, uxinzelelo lwe-fixture clamping, ulawulo lwenkqubo yokulayisha ngaphambi komthwalo kunye namanye amanyathelo ahlukeneyo anefuthe elikhulu kwiziphumo zovavanyo.
Uvavanyo lokulinganisa ubungakanani bovavanyo:
Ukulinganiswa kobukhulu kufuneka kunike ingqalelo kwizinto ezifana nonyango lomphezulu wesampuli, indawo yokulinganisa, ukudluliselwa kokubalwa kobukhulu, njl.njl., ukuze kuncitshiswe umahluko kwiziphumo.
Ukuhambelana kwendlela yokusilela:
Ulawulo olusebenzayo lweendlela zokungaphumeleli kokwaphuka kwesampulu lunokuphucula kakhulu ukuqinisekiswa kwedatha.
Iinkcukacha zovavanyo ezingentla zezinto ezidityanisiweyo zinokunceda uninzi lwabasebenzisi baqonde kwaye baqinisekise uzinzo kunye nokuthembeka kwedatha yovavanyo.
