Wake wahlangabezana nezimo ezilandelayo:
Kungani imiphumela yami yokuhlolwa kwesampula yehlulekile?
Idatha yemiphumela yokuhlolwa kwelebhu iyashintshashintsha?
Yini okufanele ngiyenze uma ukuguquguquka kwemiphumela yokuhlolwa kuthinta ukulethwa komkhiqizo?
Imiphumela yami yokuhlolwa ayihlangabezani nezidingo zamakhasimende. Ngingakuxazulula kanjani lokhu? ……
Ngezinhlelo zokusebenza ezihlanganisiwe ezibalulekile, ukuhlolwa okwengeziwe okuyinkimbinkimbi kakhulu kuyadingeka ukuze kunqunywe ukuqina kwezinto ngaphansi kwezimo zesevisi kanye nezimo ezijwayelekile. Ukukhiqiza idatha yokuhlola esezingeni eliphezulu kuyinselele enkulu ngesikhathi sokuthuthukiswa kwezinto, ukuklama kanye nezidingo zokulawula ikhwalithi.
Kulokhu, uchungechunge lwe-UP-2003 lwe-large-load electronicizinhlelo zokuhlola ezibanzikanye nemishini yokuhlola ukukhathala, kuhlanganiswe nezinto zochwepheshe ezihlanganisiwe kanye namadivayisi okulinganisa ukucindezeleka, kungahlangabezana nezidingo zokuhlola ezahlukahlukene, futhi kugxile emcabangweni olandelayo wokuhlola we-3C (Calibration, Control, Consistency) ukuqinisekisa ukuthi amakhasimende angathola idatha yokuhlola esezingeni eliphezulu ehlangabezana nemininingwane ejwayelekile ngangokunokwenzeka.
1. Ukulinganisa
Ukulinganiswa kwe-coaxiality yeketanga lokulayisha lemishini:
Ama-axes ahlukene eketanga lokulayisha angabangela kalula ukwehluleka kwesampula ngaphambi kwesikhathi. Isitifiketi se-NADCAP sibeka ukuthi iphesenti lokugoba elamukelekayo lokuhlolwa okungaguquki kwezinto ezihlanganisiwe alikho ngaphezu kuka-8%. Indlela yokuqinisekisa nokuqinisekisa i-coaxiality ngaphansi kwezimo ezahlukahlukene zokuhlola ibaluleke kakhulu.
Ukulinganiswa kwenzwa yokuphoqelela:
Izidingo zokunemba kwamandla ezinhlelo zokusebenza ezahlukene ziyahlukahluka kakhulu. Ukuqinisekisa ukunemba kwamandla ngaphakathi kobubanzi bokulinganisa kuyimfuneko yokuqinisekisa ukunemba kwemiphumela yokuhlolwa.
Ukulinganiswa kwe-Extensometer kanye ne-strain gauge:
Isixazululo sokulinganisa ubunzima obuncane esilandelekayo ukuqinisekisa ukulinganiswa kobunzima okulinganayo.
2. Ukulawula
Iphesenti lesampula lokugoba:
Izindinganiso ezahlukene zinezidingo eziqinile zokulawula iphesenti lokugoba amasampula. Kubaluleke ngokulinganayo ukuqonda izidingo ezijwayelekile kanye nokusebenza kwangempela.
Ukulawula indawo yokuhlola:
Ekuhlolweni kwezinto ezihlanganisiwe ezindaweni zokushisa eziphakeme neziphansi, kunezinkinga ezithile ezikhethekile njengokunxeshezelwa kwezinga lokushisa lama-strain gauges kanye nokulungiswa okuzenzakalelayo kwemvamisa yokuhlola, okubaluleke kakhulu emiphumeleni yokuhlola kanye nokusebenza kahle kokuhlolwa.
Ukulawula inqubo yokuhlola:
Ukulawulwa kwenqubo okuhle akuhlanganisi nje kuphela izinyathelo zokusebenza kokuhlola, kodwa futhi kufaka phakathi amarekhodi okushintsha kwendlela yokuhlola kanye nezibalo zedatha yemiphumela.
3. Ukungaguquguquki
Ukuvumelana kokuhlanganiswa kwesibonelo:
Ukuhlanganiswa kwesampula ngaphambi kokuhlolwa, ingcindezi yokubamba izinto, ukulawulwa kwenqubo yokulayisha ngaphambi kokulayisha kanye nezinye izinyathelo ezahlukene kunomthelela omkhulu emiphumeleni yokuhlolwa.
Ukulinganisa ubukhulu bokuhlola ukungaguquguquki:
Ukulinganiswa kobukhulu kudinga ukunaka izici ezifana nokwelashwa kwendawo yesampula, indawo yokulinganisa, ukudluliselwa kokubala kobukhulu, njll., ukuze kuncishiswe umehluko emiphumeleni.
Ukungaguquguquki kwemodi yokwehluleka:
Ukulawulwa okuphumelelayo kwezindlela zokwehluleka kokuqhekeka kwesampula kungathuthukisa kakhulu ukusebenza kwedatha.
Imininingwane yokuhlolwa engenhla yezinto ezihlanganisiwe ingasiza abasebenzisi abaningi ukuqonda nokuqinisekisa ukuzinza nokuthembeka kwedatha yokuhlola.
