Ukusetshenziswa kwe-Electromagnetic Flowmeter ku-Paper Industry
2022-04-24
Imboni yesimanje yamaphepha iyimboni enkulu, ubuchwepheshe, kanye nemboni yamandla ekhiqiza izinto ezinkulu. Inezici zokuqhubeka kokukhiqiza okuqinile, ukugeleza kwenqubo eyinkimbinkimbi, ukusetshenziswa kwamandla okuphezulu, umthamo omkhulu wokucubungula impahla eluhlaza, umthwalo osindayo wokungcola kanye nokutshalwa kwezimali okukhulu.
Ama-flowmeters we-electromagnetic athatha isikhundla esiphezulu embonini yephepha. Isizathu esiyinhloko ukuthi ukukalwa kwe-flowmeter kagesi akuthintwa ukuminyana, izinga lokushisa, ingcindezi, i-viscosity, inombolo ye-Reynolds kanye nezinguquko ze-conductivity zoketshezi ngaphakathi kwebanga elithile; ububanzi bayo bokulinganisa bukhulu kakhulu futhi bungakwazi ukumboza kokubili ukugeleza kwe-turbulent kanye ne-laminar. Ukusatshalaliswa kwesivinini, okungenakuqhathaniswa namanye amamitha okugeleza. Ngenxa yesakhiwo esilula se-flowmeter ye-electromagnetic flowmeter, azikho izingxenye ezihambayo, izingxenye eziphazamisayo nezingxenye ezishayayo ezivimbela ukugeleza kwendawo elinganisiwe, futhi ngeke kube nezinkinga ezifana nokuvinjelwa kwamapayipi nokugqoka. Ingasindisa kakhulu ukusetshenziswa kwamandla futhi ilawule ngokuqinile ukukhishwa kwezinto ezingcolisa imvelo.
Isiphakamiso sokukhetha imodeli semitha yokugeleza kagesi.
1. Ulayini
I-medium elinganisiwe enkambisweni yokwenza iphepha inezici zokushisa okuphezulu nokucindezela okukhulu, futhi inenani elikhulu lamakhemikhali, elidlayo. Ngakho-ke, ama-flowmeters kagesi wonke ahlanganiswe ne-PTFE ukumelana nokushisa okuphezulu. Nakuba ulayini lwe-PTFE lumelana nezinga lokushisa eliphezulu, alumelani nengcindezi engemihle. Kwezinye izindawo ezikhethekile, ezifana nokuphuma kwe-medium-concentration riser, hhayi kuphela ukugxila okuphakathi okuphezulu, izinga lokushisa liphezulu, kodwa futhi i-vacuum phenomenon izokwenzeka ngezikhathi ezithile. Kulokhu, kubalulekile ukukhetha i-PFA lining.
2. Ama-Electrodes
Ukukhethwa kwama-electromagnetic flowmeter electrode embonini yephepha ikakhulukazi kubheka izici ezimbili: eyodwa ukumelana nokugqwala; enye i-anti-scaling.
Inani elikhulu lamakhemikhali lizokwengezwa kwinqubo yokwenza iphepha, njenge-NaOH, i-Na2SiO3, i-H2SO4 egxilile, i-H2O2, njll. Ama-electrode ahlukene adinga ukukhethwa kumakhemikhali ahlukene. Isibonelo, ama-electrode e-tantalum kufanele asetshenziselwe ama-electric acid e-acid aqinile, ama-electrode e-titanium ngokuvamile asetshenziselwa imidiya ye-alkali, futhi ama-electrode ensimbi engagqwali angu-316L angasetshenziswa ukukala amanzi okuvamile.
Ekwakheni ama-electrode aphikisana nokungcoliswa, ama-electrode ayindilinga angakhethelwa okuphakathi kakhulu okuhlanganiswe izinto ezine-fibrous ngezinga elijwayelekile lokungcoliswa. I-electrode eyindilinga inendawo enkulu yokuxhumana nendawo elinganisiwe futhi ayimbozwa kalula izinto ezinemicu.
