Kushandiswa kweElectromagnetic Flowmeter muIndasitiri yePepa
2022-04-24
Indasitiri yemazuva ano yemapepa iguta guru, tekinoroji, uye indasitiri ine simba rakawanda ine kugadzirwa kwakakura. Iyo ine hunhu hwekuenderera kwekugadzirwa kwakasimba, kuyerera kwemaitiro akaomarara, kushandiswa kwesimba rakawanda, hombe mbichana yekugadzirisa huwandu, inorema kusvibiswa mutoro uye hombe mari.
Electromagnetic flowmeters inogara pachinzvimbo chikuru muindasitiri yemapepa. Chikonzero chikuru ndechekuti kuyerwa kweiyo electromagnetic flowmeter haina kukanganiswa nedensity, tembiricha, kudzvanywa, viscosity, Reynolds nhamba uye conductivity shanduko yemvura mukati meimwe siyana; kuyerwa kwayo kwakakura kwazvo uye inogona kuvhara zvese mhirizhonga uye laminar kuyerera. Velocity kugovera, iyo isingaenzaniswi nemamwe mamita ekuyerera. Nekuda kwechimiro chakareruka cheiyo electromagnetic flowmeter, hapana zvikamu zvinofamba, zvinokanganisika zvikamu uye throttling zvikamu zvinotadzisa kuyerera kweyakayerwa svikiro, uye hapazove nematambudziko akadai sekuvharika kwepombi uye kupfeka. Inogona kuchengetedza zvakanyanya kushandiswa kwesimba uye kunyatso kudzora kubuda kwezvinosvibisa zvakatipoteredza.
Kurudziro yekusarudza modhi ye electromagnetic kuyerera mita.
1. Lining
Iyo yakayerwa yepakati mukugadzira mapepa ine hunhu hwekupisa kwepamusoro uye kudzvanywa kwepamusoro, uye ine huwandu hukuru hwemakemikari, ayo anoparadza. Naizvozvo, iwo emagetsi emagetsi anoyerera ese akamisikidzwa nepamusoro tembiricha inodzivirira PTFE. Kunyangwe iyo PTFE lining inopesana nekushisa kwepamusoro, haidziviriri kumanikidziro asina kunaka. Mune dzimwe nzvimbo dzakakosha, dzakadai sekubuda kwe-medium-concentration riser, kwete chete chiyero chepakati chakakwirira, tembiricha yakakwira, asiwo chiitiko chevacuum chichaitika nguva nenguva. Muchiitiko ichi, zvinodikanwa kusarudza PFA lining.
2. Maelectrodes
Kusarudzwa kwe electromagnetic flowmeter electrodes muindasitiri yemapepa inonyanya kufunga nezvezvinhu zviviri: imwe ndeyekupokana; imwe yacho inopesana nekukura.
Kuwanda kwemakemikari kuchawedzerwa mukugadzirwa kwepepa, zvakadai seNaOH, Na2SiO3, yakanyanyisa H2SO4, H2O2, etc. Ma electrode akasiyana-siyana anoda kusarudzwa kumakemikari akasiyana. Semuyenzaniso, maelectrodes etantalum anofanirwa kushandiswa kune yakasimba acid dielectric electrode, titanium electrodes anowanzo shandiswa kune alkaline media, uye 316L Stainless simbi maelectrodes anogona kushandiswa kuyera mvura.
Mukugadzirwa kweanopesana nekusvibisa maelectrodes, spherical electrodes inogona kusarudzirwa yepakati kunyanya inoumbwa nefibrous zvinhu kune iyo general degree yekusvibisa. Iyo spherical electrode ine hombe yekuonana nenzvimbo ine yakayerwa yepakati uye haifukidzwe nyore nezvinhu zvine fibrous.
