Ukulinganisa izinga elingathintani kungenye yezindlela zobuchwepheshe ezibalulekile ezenzakalelayo zezimboni. Le ndlela ivumela ukuqapha amazinga oketshezi noma aqinile ethangini, esitsheni noma emseleni ovulekile ngaphandle kokuxhumana ngokomzimba nendawo ephakathi nendawo. Phakathi kwezindlela ezingathintani ezisetshenziswa kakhulu yi-ultrasonic kanye namamitha ezinga le-radar. Uma umsebenzisi engathanda ukusebenzisa isilinganiso esingathintani ekulawuleni izinga, ukuqonda ukusebenza kwama-ultrasonic kanye nama-radar type level gauges kusiza ekwenzeni ukukhetha okufanele kwesimo esithile.
Isimiso sokusebenza
Amageyiji e-Ultrasonic levelzisebenza ngokukhipha ukuqhuma kwamagagasi omsindo okuvama kakhulu ukuthola ububanzi kusukela ku-sensor kuya kobuso be-liquid/solid medium. Lawa magagasi ahamba emoyeni, abonise ubuso bezinto ezibonakalayo, bese ebuyela ku-sensor. Ibanga linganqunywa ngesikhathi esichithwa ohambweni lwamagagasi. Ngakho-ke ithuluzi lifakwa ebangeni elingaphezu kobuso obuphakathi, ngaphandle kokuthi noma iyiphi ingxenye kufanele ithintwe ngqo noma ifakwe emanzini.
Amageyiji wezinga le-radarisebenzisa amaza kagesi (ama-microwave) esikhundleni somsindo ukuze inqume izinga eliphakathi loketshezi noma okuqinile. Ngokufanayo amasignali e-microwave akhishwa aye endaweni ephakathi bese eboniswa futhi abuyiselwe ethuluzini. Phakathi nenqubo futhi akukho ukuxhumana ngokomzimba phakathi komzimba wethuluzi kanye nendawo. Ngesikhathi sokuqopha isikhathi sokundiza kwamasignali amaza, ibanga ukusuka ethuluzini kuya endaweni ebonakalayo lingabalwa.
Ukulinganisa amazinga kwalezi zinhlobo ezimbili kwabelana ngamafomula afanayo:
D = (C*T)/2
L = H - D
Kuphi,
D: Ibanga ukusuka endaweni ephakathi nendawo kuya ethuluzini
C: Isivinini somsindo (se-ultrasound) isivinini sokukhanya (se-radar)
T: Isikhathi esiphakathi kusukela ekukhishweni komoya kuya ekutholeni
L: Izinga eliphakathi okufanele lilinganiswe
H: Ukuphakama kusukela phansi kwesitsha kuya ethuluzini
Ngokungafani nezinsimbi ezivamile ezisekelwe ekuthinteni, ukususwa kokuthintana ngokomzimba nento, ubuchwepheshe be-ultrasonic kanye ne-radar buhamba phambili ekulawuleni izinga lezinto ezibolayo, eziqinile, noma eziyingozi ezingalimaza noma zivale izingxenye ezimanzi njengezintantayo, ama-probe, noma imigqa ye-impulse. Ukufakwa kwenziwa lula njengoba amadivayisi efakwa ngaphandle futhi isidingo sokugcinwa nesikhathi sokungasebenzi sivame ukugcinwa sincane ngenxa yomklamo ongangenisi ukungcola. Izimboni ezifana nokucubungula amakhemikhali, ukwelashwa kwamanzi, kanye nokukhiqizwa kokudla zingazuza kakhulu ezinzwa zezinga le-ultrasonic kanye ne-radar ezingezona ezithintana ngenxa yokuguquguquka kwazo kanye nokuthembeka kwazo phakathi kokulawulwa kwenqubo koketshezi, uketshezi, i-slurry, kanye nokuqina kuzo zonke izinhlobo zamajiyometri ethangi.
Ukuqhathanisa phakathi kwe-ultrasonic ne-radar
Imitha yezinga le-Ultrasonic kulula ukuyifaka futhi idinga ukusethwa okuncane. Uma iqhathaniswa nemitha yezinga le-radar, le-ultrasonic ivame ukubiza kancane futhi ngenxa yalokho ikhethwa kakhulu ekusetshenzisweni okunemikhawulo yesabelomali. Kodwa-ke, ukusebenza kwezinsimbi ze-ultrasonic kuncike kakhulu emiphumeleni yemvelo yothuli, igwebu, ukuxokozela komoya kanye nokushisa okukhulu kanye nomswakama okungamunca noma kuphambukise amaza omsindo futhi kubangele inkinga yamaza alahlekile.
Ngakolunye uhlangothi, i-radar level gauge yaziwa ngokunemba okuphezulu, ibanga elide kanye nokuthembeka okuqinisekisiwe ezindaweni zokusebenza ezinzima. Ayithinteki kakhulu yizici ezingaphezu kwalokho okubangela ubunzima kubuchwepheshe be-ultrasonic. Noma kunjalo kusho ukuthi imikhiqizo ye-radar ngokuvamile ibiza kakhulu. I-dielectric constant ingenye into ebalulekile yokulinganisa i-radar. Izinto eziphansi ze-dielectric zingenza buthaka ukubonakaliswa kwesignali ye-echo okuholela ekulinganisweni okungazinzile noma okulahlekile.
Ngamafuphi, lapho umsebenzisi enquma ukusebenzisa izinga lokulinganisa elingathintani, inzwa ye-ultrasonic izoba ngcono kakhulu esimweni esimaphakathi sokusebenza kanye nomsebenzi oqaphela isabelomali ngenkathi i-radar ifanelekela indawo enzima kakhulu kanye nokuphishekela izinga eliphezulu lokulinganisa. Kunoma ikuphi, kubalulekile ukuqinisekisa ukuthi izici eziphakathi nendawo kanye nendawo, kanye nesakhiwo sohlelo lwenqubo, zilungele ukusetshenziswa kwendlela yokulinganisa efiselekayo yokungenathintana.
Amanothi okufakwa kwezinsimbi ezingenakuthinta
- ✦ Indawo yokufaka kufanele ibe kude ngangokunokwenzeka nomthombo womsindo
- ✦ I-gasket yerabha ingasetshenziswa ukuyifaka ngaphansi kwendawo yokudlidliza
- ✦ Ibanga elisuka ku-sensor liye ezingeni eliphakeme kakhulu elilinganisiwe kufanele libe likhulu kune-blind zone yokulinganisa
- ✦ Indawo yenzwa kufanele igcine ibanga elithile nodonga lwesitsha ngokwe-engeli yokukhipha
- ✦ Indawo yokulinganisa kufanele ingabi nezithiyo ezingase zibangele ukuphazamiseka kwesignali njengesitebhisi sezinyathelo noma ugongolo oluphambeneyo
- ✦ Ukuze kulinganiswe kahle okuphakathi nendawo, indawo yokufaka kufanele igweme indawo yokuvula ukudla kwezinto ezibonakalayo
- ✦ Kungcono ukugwema ukushintshashintsha okukhulu kwezinga lokushisa endaweni yokufakwa kwemishini
- ✦ I-sensor probe kufanele iqonde ngqo endaweni ephakathi nendawo ukuze iqinisekise ukusebenza okuhle kakhulu
Shanghai Wangyuaningumkhiqizi wezinsimbi onolwazi iminyaka engaphezu kwengu-20 ehlinzeka ngezinzwa zezinga lokuxhumana ze-ultrasonic kanye ne-radar kanye nezinye izinhlobo zamathuluzi okulinganisa izinga. Sicela uzizwe ukhululekile ukuxhumana nathi ngemibuzo yakho ngemikhiqizo yokulinganisa izinga lokuxhumana.
