Wake wahlangabezana nalezi zimo ezilandelayo:
Kungani umphumela wami wokuhlolwa wesampula uhlulekile?
Idatha yomphumela wokuhlolwa welabhorethri iyashintshashintsha?
Yini okufanele ngiyenze uma ukuhlukahluka kwemiphumela yokuhlolwa kuthinta ukulethwa komkhiqizo?
Imiphumela yami yokuhlolwa ayihlangabezani nezidingo zekhasimende. Indlela yokuyixazulula? ……
Kuzinhlelo zokusebenza eziyinhlanganisela ebalulekile, inkimbinkimbi kakhudlwana, ukuhlolwa okwengeziwe kuvame ukudingeka ukuze kunqunywe ukuqina kwento ngaphansi kwezimo zesevisi kanye nezindawo ezivamile. Ukukhiqiza idatha yokuhlola yekhwalithi ephezulu kuyinselele enkulu phakathi nezidingo zokuthuthukiswa kwezinto, ukuklama nokulawula ikhwalithi.
Mayelana nalokhu, uchungechunge lwe-UP-2003 lomthwalo omkhulu we-electronicizinhlelo zokuhlola jikelelenemishini yokuhlola ukukhathala, kuhlanganiswe nezinto ezilungiswayo eziyinhlanganisela yochwepheshe namadivayisi okulinganisa ubunzima, ingahlangabezana nezidingo ezahlukahlukene zokuhlola, futhi igxile kulo mqondo wokucaciswa kokuhlolwa kwe-3C (Calibration, Control, Consistency) ukuze kuqinisekiswe ukuthi amakhasimende angathola idatha yokuhlola yekhwalithi ephezulu ihlangabezana nokucaciswa okujwayelekile ngangokunokwenzeka.
1.Ukulinganisa
Isisetshenziswa sokulayisha i-coaxiality chain calibration:
Izimbazo ezihlukene zeketango lokulayisha kalula zingabangela ukwehluleka ngaphambi kwesikhathi kwesifanekiso. Isitifiketi se-NADCAP sibeka ukuthi iphesenti elamukelekayo lokugoba lokuhlolwa okumile lezinto eziyinhlanganisela alikho ngaphezu kuka-8%. Indlela yokuqinisekisa nokuqinisekisa ukuthi i-coaxiality ngaphansi kwezimo ezihlukahlukene zokuhlola ibaluleke kakhulu.
Phoqa ukulinganiswa kwenzwa:
Izidingo zokunemba kwamandla kwezinhlelo zokusebenza ezahlukene ziyahlukahluka kakhulu. Ukuqinisekisa ukunemba kwamandla ngaphakathi kwebanga lokulinganisa kuyimfuneko yokuqinisekisa ukunemba kwemiphumela yokuhlolwa.
Ukulinganiswa kwe-Extensometer kanye ne-strain gauge:
Isixazululo sokulinganisa i-micro-strain esilandelekayo ukuze kuqinisekiswe ukulinganisa okungaguquguquki kobunzima.
2. Ukulawula
Iphesenti lokugoba isampula:
Amazinga ahlukene anezidingo eziqinile zokulawula iphesenti lokugoba isampula. Kubaluleke ngokufanayo ukuqonda izidingo ezijwayelekile kanye nokusebenza kwangempela.
Ukulawula indawo yokuhlola:
Ukuhlolwa kwezinto eziyinhlanganisela ezindaweni zokushisa eziphakeme neziphansi, kunokukhathazeka okuthile okukhethekile okufana nokunxeshezelwa kwezinga lokushisa lamageji obunzima nokulungiswa okuzenzakalelayo kwemvamisa yokuhlola, okubaluleke kakhulu emiphumeleni yokuhlola nokusebenza kahle kokuhlolwa.
Ukulawula inqubo yokuhlola:
Ukulawulwa kwenqubo okuhle akuhlanganisi nje kuphela izinyathelo zokusebenza kokuhlolwa, kodwa futhi kufaka phakathi amarekhodi ezinguquko zendlela yokuhlola kanye nezibalo zedatha yemiphumela.
3. Ukungaguquguquki
Ukuhambisana kokuhlanganiswa kwesifanekiso:
Ukuhlanganiswa kwesampula ngaphambi kokuhlolwa, ingcindezi ye-fixture clamping, ukulawulwa kwenqubo yokulayisha ngaphambilini nezinye izinyathelo ezihlukene kunomthelela omkhulu emiphumeleni yokuhlolwa.
Hlola ukuvumelana kokulinganisa kobukhulu:
Isilinganiso sobukhulu sidinga ukunaka izinto ezifana nokwelashwa kwendawo eyisampula, indawo yokulinganisa, ukudluliswa kokubala kobukhulu, njll., ukuze kwehliswe umehluko emiphumeleni.
Ukungaguquguquki kwemodi yokwehluleka:
Ukulawula okusebenzayo kwezibonelo zokuhluleka ukuphuka kungathuthukisa kakhulu ukufaneleka kwedatha.
Ukucaciswa okungenhla kokuhlolwa kwezinto eziyinhlanganisela kungasiza abasebenzisi abaningi baqonde futhi baqinisekise ukuzinza nokuthembeka kwedatha yokuhlola.
