Ukuhlaziywa Kwemiso Yokusebenza Nezimpawu Zezinhlobo Ezihlukahlukene Ze-flowmeters

Ama-flowmeters amehlo okukhiqizwa kwezimboni futhi ahlobene kakhulu nomnotho kazwelonke, ukwakhiwa kwezokuvikela kuzwelonke, nocwaningo lwesayensi. Zithatha isikhundla esibalulekile nomsebenzi emnothweni kazwelonke futhi zingasetshenziselwa ukukala ukugeleza kwegesi, uketshezi, umusi kanye neminye imidiya. Ukuze sikhombise kangcono umgomo wokulinganisa ukugeleza, ake sethule umgomo wokusebenza nezici zama-flowmeter ahlukile.

Ⅰ. I-Orifice flowmeter:

1. Isimiso sokusebenza

Lapho uketshezi lugcwalisa ipayipi futhi ligeleza ngedivayisi ye-throttling phakathi kwepayipi, ugongolo lokugeleza luzokwehla endaweni, ukuze ijubane lokugeleza likhuphuke futhi ingcindezi emile iphansi, ngakho-ke ukwehla kwengcindezi kwenzeka ngaphambi nangemva kwesiqephu, okungukuthi, umehluko wengcindezi, Lapho kugeleza kakhulu izinga lokugeleza eliphakathi. Uma umehluko wengcindezi kukhulu, umehluko wengcindezi wenziwa ngaphambi nangemva kwe-throttle, ngakho-ke i-orifice flowmeter ingalinganisa ukugeleza koketshezi ngokukala umehluko wengcindezi. Le ndlela yokulinganisa isuselwa emthethweni wokongiwa kwamandla kanye nomthetho wokuqhubeka kokugeleza.

2. Izici zokusebenza

① Idivayisi yokuthimba inesakhiwo esilula nesiqinile, ukusebenza okuzinzile futhi okuthembekile, impilo yensizakalo ende nentengo ephansi;

② Uhla olubanzi lwezicelo, konke ukugeleza kwesigaba esisodwa kungalinganiswa, futhi okunye ukugeleza kwesigaba esixubekile nakho kungasetshenziswa;

③ Idivayisi ejwayelekile yokuthimba ingasetshenziswa ngaphandle kokulinganiswa kokugeleza kwangempela;

④ Ukufakwa kwepuleti elihlanganisiwe kulula, akukho ipayipi lengcindezi elidingekayo, futhi ingaxhunywa ngqo kumdlulisi wengcindezi ohlukile kanye nomdlulisi wengcindezi.

Ⅱ. I-electromagnetic flowmeter

1. Isimiso sokusebenza

Ngokuya ngomthetho kaFaraday wokungeniswa kwe-electromagnetic. Ku-electromagnetic flowmeter, ukuqhutshwa kweshubhu lokulinganisa kulingana nenduku yensimbi yokuqhuba ekuhlolweni kweFaraday, futhi amakhoyili amabili kagesi emaphethelweni aphezulu nangaphansi akhiqiza ukungaguquguquki kukazibuthe. Lapho ukuqhuba okuhambayo kugeleza, kuzokhiqizwa amandla kagesi. Ama-electrode amabili ngaphakathi kwepayipi alinganisa amandla kagesi okwenziwe. Ithubhu lokulinganisa lihlukaniswe ngogesi noketshezi kanye ne-electrode yokulinganisa ngokusebenzisa i-lineng engaqhubekanga (i-rubber, I-Teflon, njll.)..

2. Izici zokusebenza

① Yiba nohlelo lokulinganisa lwezindlela ezimbili;

② Isigaba samapayipi oqondile esidingwa yinzwa sifushane, futhi ubude buphindwe ka-5 ububanzi bepayipi;

③ Ukulahleka kwengcindezi encane;

④ Isilinganiso asithinteki yizinguquko zobuningi obuketshezi, i-viscosity, izinga lokushisa, ingcindezi nokuqhuba;

⑤ Okusetshenziswa kakhulu ekwelashweni kwendle.

Ⅲ. I-Turbine flowmeter

1. Isimiso sokusebenza

Ngaphakathi kwebanga elithile lokugeleza, ijubane lokujikeleza le-turbine lilingana nezinga lokugeleza koketshezi. Ukugeleza koketshezi kuqhuba i-turbine ukujikeleza, futhi ijubane lokujikeleza le-turbine liguqulwa libe ama-pulses kagesi, futhi idatha ikhonjiswa itafula lesibili, elikhombisa izinga lokugeleza koketshezi.

2. Izici zokusebenza

① Ukumelana okuqinile kokungcola;

② Ukuphazamiseka okuqinile okulwa no-electromagnetic kanye nekhono elwa no-seismic;

③ Isakhiwo nomgomo wayo kulula futhi kulula ukugcina;

④ Cishe akukho ukulahleka kwengcindezi, okulondoloza ukusetshenziswa kwamandla.

Ⅳ. I-Volumetric flowmeter

1. Isimiso sokusebenza

Lapho uketshezi ludlula ku-flowmeter, umehluko othile wengcindezi uzokwakhiwa phakathi kokungena nokuphuma kwe-flowmeter. Ingxenye ejikelezayo ye-flowmeter (ebizwa nge-rotor) ijikeleza ngaphansi kwesenzo salo mehluko wengcindezi futhi ikhiphe uketshezi kusuka ekungeneni kuya endaweni. Phakathi nale nqubo, uketshezi lugcwalisa "isikhala se-metering" se-flowmeter kaningi, bese luthunyelwa ngokuqhubekayo endaweni. Ngaphansi kwezimo ze-flowmeter enikeziwe, ivolumu yendawo yokulinganisa iyanqunywa, futhi inqobo nje uma inani lokujikeleza kwe-rotor kulinganiswa, inani elihlangene levolumu uketshezi elidlula ku-flowmeter lingatholakala.

2. Izici zokusebenza

① Ukunemba kokulinganisa okuphezulu;

② Izimo zepayipi lokufaka azinamthelela ekunembeni kokulinganisa;

③ Ingasetshenziselwa ukukala koketshezi oluphezulu lwe-viscosity;

④ Ibanga elibanzi;

⑤ TIInsimbi yokufunda ngqo ingathola ngqo ukuqongelela ngaphandle kwamandla angaphandle, inani eliphelele licacile futhi kulula ukusebenza;

⑥ Isakhiwo siyinkimbinkimbi futhi ivolumu inkulu;

⑦ Akufanele izikhathi zokushisa eziphakeme neziphansi;

⑧ Izinsimbi eziningi zilungele kuphela uketshezi oluhlanzekile lwesigaba esisodwa;

⑨ Umsindo nokudlidliza kukhulu.
