Zochitika Pamene Sizingagwiritsidwe Ntchito Ma Gauge Okhuthala​

Choletsa chachikulu chimachitika pochita zinthu zomwe sizikugwirizana ndi mfundo yoyezera ya geji. Mwachitsanzo, ma gauge a makulidwe a ultrasonic amadalira kutumiza ndi kuwunikira kwa mafunde a ultrasound kudzera muzinthu. Ngati zinthuzo zili ndi kuyamwa kwakukulu kwa mafunde a ultrasound, monga zinthu zokhala ndi ma pore kwambiri monga ma aerogel kapena mitundu ina ya thovu loyamwa phokoso, mafunde a ultrasound adzachepetsedwa kwambiri kapena kulowetsedwa kwathunthu asanafike kumbuyo kuti awonetse. M'mikhalidwe yotere, gejiyo singapeze zizindikiro zofunikira za echo kuti iwerengere makulidwe molondola, zomwe zimapangitsa kuti isagwire ntchito. Mofananamo, ma gauge a makulidwe ozikidwa pa electromagnetic, omwe amagwira ntchito pa mfundo ya electromagnetic induction kapena eddy currents, sali oyenera zinthu zomwe sizimayendetsa magetsi. Popeza zinthu zomwe sizimayendetsa magetsi sizimalumikizana ndi minda ya electromagnetic mwanjira yofunikira, ma gauge awa sangapereke miyeso yofunikira ya makulidwe.​

Chinthu china chomwe ma geji a makulidwe sagwiritsidwa ntchito ndi pamene pamwamba pa chinthucho pali mkhalidwe woipa kwambiri. Malo owuma, osafanana, kapena ovunda kwambiri angayambitse mavuto akulu. Pa ma geji a makulidwe amtundu wa contact, monga ma micrometer kapena ma dial gauges, malo osafanana amachititsa kuti zikhale zovuta kuonetsetsa kuti kulumikizana ndi kulumikizana koyenera ndikugwirizana, zomwe zimapangitsa kuti kuwerenga kusasinthasintha komanso kolakwika. Ngakhale pa ma geji osakhudzana monga laser kapena optical thickness gauges, malo osasinthasintha kwambiri angapangitse kuti mtanda woyezera ubalalike kapena kuonekera m'njira zosayembekezereka, zomwe zimalepheretsa kudziwa bwino makulidwe. Komanso, ngati pamwambapo paipitsidwa ndi dothi lokhuthala, mafuta, kapena zinthu zina, zimatha kusokoneza njira yoyezera. Mwachitsanzo, pankhani ya ma geji a ultrasound, malo odetsedwa angasokoneze kulumikizana pakati pa transducer ndi chinthucho, zomwe zimakhudza kufalikira kwa mafunde a ultrasound ndikupangitsa kuti miyeso ikhale yolakwika.​

Mkhalidwe wa chilengedwe umagwiranso ntchito yofunika kwambiri pakugwiritsa ntchito ma gauge a makulidwe. Malo otentha kwambiri angayambitse mavuto pamitundu yambiri ya ma gauge. Ma gauge ena, makamaka omwe ali ndi zida zamagetsi kapena zida zamakaniko, amatha kuwona kutentha kapena kuwonongeka kwa zinthu kutentha kwambiri, zomwe zimasintha kuwerengera kwawo komanso kulondola kwawo. Mwachitsanzo, zinthu za piezoelectric mu ma transducer a ultrasonic zimatha kutaya magwiridwe antchito awo kapena kusintha mawonekedwe awo ogwirira ntchito zikakumana ndi kutentha kwakukulu kwa nthawi yayitali. Mu kutentha kochepa kwambiri, zinthu zimatha kusweka kapena kusintha mawonekedwe awo, zomwe zingakhudzenso zotsatira za muyeso. Kuphatikiza apo, m'malo omwe ali ndi chinyezi chambiri, chinyezi chingawononge zigawo zamkati za ma gauge a makulidwe amagetsi kapena kukhudza kulumikizana kwa ma gauge a ultrasonic, zomwe zimapangitsa kuti zisadalirike.​

Pamene mawonekedwe a chinthu chomwe chikuyesedwa ndi ovuta kapena osafikirika, ma geji a makulidwe sangagwire ntchito bwino. Mwachitsanzo, kuyeza makulidwe a zigawo zamkati mu kapangidwe kovuta, komwe gauge silingafikire poyezera n'kosatheka. Komanso, pazinthu zomwe zili ndi magawo ang'onoang'ono kapena opapatiza omwe ndi ochepa kuposa mulingo wocheperako wa gauge, kudziwa makulidwe molondola kumakhala kosatheka. Ma geji ena a makulidwe amafuna malo enaake athyathyathya komanso okhazikika kuti ayezedwe, ndipo ngati chinthucho chili ndi mawonekedwe apadera omwe sakwaniritsa zofunikirazi, gauge singagwiritsidwe ntchito bwino.​

Pomaliza, ngakhale kuti ma gauge a makulidwe ndi zida zofunika kwambiri pa ntchito zosiyanasiyana, pali zochitika zambiri zomwe sizingagwiritsidwe ntchito. Izi zikuphatikizapo kusagwirizana kwa zinthu, mikhalidwe yoopsa kwambiri pamwamba, zinthu zoyipa zachilengedwe, ndi ma geometri ovuta kapena osafikirika. Kuzindikira zofooka izi ndikofunikira posankha njira zoyenera zoyezera ndikutsimikizira kudalirika kwa deta yokhudzana ndi makulidwe.
