Iimitha zokuhamba kwe-ultrasoniczisetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yokungabi namdla, ukuchaneka okuphezulu, kunye nokukwazi ukulinganisa uluhlu olubanzi lokuhamba kolwelo. Nangona kunjalo, ukusebenza kwee-flowmeters ze-ultrasonic kunokuchaphazeleka kakhulu bubushushu bolwelo olulinganisiweyo. Ukuqonda iimfuno zee-flowmeters ze-ultrasonic zobushushu bolwelo kubalulekile ukuqinisekisa ukuchaneka nokuthenjwa.umlinganiselo wokuhamba kwamanzi.
1. Uluhlu lobushushu oluqhelekileyo
Uninziii-flowmeters ze-ultrasoniczenzelwe ukusebenza ngaphakathi koluhlu oluthile lobushushu. Ngokwesiqhelo, uluhlu lobushushu oluqhelekileyo lokusebenza kwiimitha zokuhamba ze-ultrasonic ezisetyenziswa kwizicelo zoshishino luqala kwi - 20°C ukuya kwi-120°C. Olu luhlu lujongana neemeko ezininzi zokulinganisa ukuhamba kolwelo, njengakwiinkqubo zokubonelela ngamanzi, izityalo zokucubungula iikhemikhali, kunye namashishini okutya neziselo. Umzekelo, kwiziko lokucoca amanzi likamasipala, apho ubushushu bamanzi buhlala butshintsha phakathi kwe-0°C kunye ne-30°C, iimitha zokuhamba ze-ultrasonic ngaphakathi kolu luhlu lobushushu ngokubanzi zinokusebenza ngokufanelekileyo.
2. Impembelelo yamaqondo obushushu aphantsi
2.1 Ukutshintsha kwe-Viscosity kunye ne-Acoustic Velocity
Xa ubushushu bolwelo buhla ngaphantsi komda ophantsi woluhlu olucetyiswayo, i-viscosity yolwelo idla ngokunyuka. Umzekelo, kwimeko yeeoyile ezithile, njengoko ubushushu buhla, ioyile iba nkulu, nto leyo enokuthintela ukusasazeka kwamaza e-ultrasonic ngolwelo. Ukongeza, isantya sesandi kulwelo siyancipha ngokuhla kobushushu. Ekubeni ii-ultrasonic flowmeters zixhomekeke ekulinganisweni kwexesha - lokubhabha okanye ukutshintsha kweDoppler kwamaza e-ultrasonic, olu tshintsho kwisantya se-acoustic lunokukhokelela ekulinganisweni kokugeleza okungachanekanga. Ukuba ubushushu buphantsi kakhulu, ulwelo lunokukhenkceza, nto leyo enokonakalisai-flowmeter's okanye uvale indlela yokuhamba, nto leyo eyenza i-flowmeter ingasebenzi.
2.2 Ukuhambelana kwezinto
Amaqondo obushushu aphantsi anokuchaphazela nezinto ezisetyenziswa kwi-ultrasonic flowmeters. Ezinye iiplastiki kunye nee-elastomers ezisetyenziswa ekwakhenii-flowmeterIzinto ezisetyenzisiweyo zinokuba buthathaka xa kushushu kakhulu. Oku buthathaka kunokubangela ukuqhekeka okanye ukwaphuka kwezinto ezisetyenzisiweyo, nto leyo ekhokelela ekuvuthweni okanye ekungasebenzini kwe-sensor. Umzekelo, ii-gaskets kunye nezitywino ezenziwe ngee-polymers ezithile zinokulahlekelwa bubuthambile bazo kunye neempawu zokutywina, okuvumela umoya okanye ezinye izinto ezingcolisayo ukuba zingene kwi-flowmeter, nto leyo enokubangela ukuba ukuchaneka komlinganiselo kube buthathaka ngakumbi.
3. Impembelelo yamaqondo obushushu aphezulu
3.1 Ukwehla kokusebenza kweSensor
Kumaqondo obushushu aphezulu, ngaphezu komda ophezulu woluhlu oluchaziweyo lokusebenza, ukusebenza kwee-sensors ze-ultrasonic kunokwehla. Izixhobo ze-piezoelectric ezisetyenziswa kwi-ultrasonic transducers zinokufumana ukwehla kwe-piezoelectric coefficient yazo njengoko ubushushu bunyuka. Oku kuncipha kuthetha ukuba ii-transducers azikwazi kakuhle ukuguqula amandla ombane abe ngamaza e-ultrasonic kwaye ngokuchaseneyo. Ngenxa yoko, amandla esignali afunyanwa yi-flowmeter's receiver anokuba buthathaka, nto leyo ekhokelela kwiimpazamo ekulinganisweni kokuhamba.
3.2 Utshintsho lweekhemikhali kunye nolwelo kulwelo
Ulwelo oluphezulu lunokutshintsha ngokwekhemikhali okanye ngokwasemzimbeni okunokuchaphazela umlinganiselo wokuhamba kwamanzi. Umzekelo, kwezinye iinkqubo zeekhemikhali, ubushushu obuphezulu bunokubangela ukuba ulwelo lubole okanye luphendulane nezinto ezimanzi ze-flowmeter. Oku kunokukhokelela ekwakhiweni kweediphozithi okanye ukugqwala kwiindawo zangaphakathi ze-flowmeter, okutshintsha iimpawu zokuhamba kwamanzi kunye nokubangela ukufundwa okungachanekanga. Ngaphezu koko, ulwelo oluphezulu lunokuba noxinano oluphantsi, kwaye utshintsho kuxinano lunokuchaphazela ubudlelwane phakathi kokusasazwa kwamaza e-ultrasonic kunye nesantya sokuhamba kwamanzi sokwenyani, okubangela iimpazamo zokulinganisa.
4. Imbuyekezo yobushushu
Ukujongana nemingeni ebangelwa kukutshintshatshintsha kobushushu bolwelo, uninziii-flowmeters ze-ultrasoniczixhotyiswe ngeendlela zokuhlawula ubushushu. Ezi ndlela zinokuba zezehardware okanye zesoftware. Ukuhlawula ubushushu okusekelwe kwihardware kudla ngokubandakanya ukusebenzisa ezinye iisensa zobushushu ezibekwe kufutshane necandelo lokulinganisa le-ultrasonic flowmeter. Ezi sensa zobushushu zihlala zijonga ubushushu bolwelo, kwaye ii-elektroniki ze-flowmeter zisebenzisa olu lwazi ukulungisa ii-algorithms zokulinganisa. Ukuhlawula okusekelwe kwisoftware, kwelinye icala, kuxhomekeke kwii-algorithms ezicwangcisiweyo kwangaphambili eziqwalasela ulwalamano olwaziwayo phakathi kobushushu, isantya se-acoustic, kunye nesantya sokuhamba. Ngokusebenzisa ezi algorithms, i-flowmeter ingalungisa iimpazamo ezibangelwa bubushushu kwaye ibonelele ngemilinganiselo yokuhamba echanekileyo ngakumbi kuluhlu olubanzi lobushushu.
Ukuqukumbela, ubushushu bolwelo olulinganiswayo yinto ebalulekileyo echaphazela kakhulu ukusebenza kwaloii-flowmeters ze-ultrasonicUkuqonda uluhlu lobushushu ngokubanzi, imiphumo yobushushu obuphantsi nophezulu, kunye nokubaluleka kokulungiswa kobushushu kubalulekile ekufakweni, ekusebenzeni, nasekugcinweni kwee-flowmeters ze-ultrasonic ngokufanelekileyo. Ngokulandela ezi mfuno, abasebenzisi banokuqinisekisa ukulinganiswa kokuhamba kolwelo okuthembekileyo nokuchanekileyo kwizicelo ezahlukeneyo zoshishino nezorhwebo.
