Nekutevera mafambiro aya, mafekitori anogona kushandisa nzira dzakanakisisa dzekugadzirisa kuvharwa kwemagetsi musati mave nedambudziko remidziyo, zvichizadzisa chinodiwa chikuru chekudzivirira kutadza ngura mumidziyo yeindasitiri.
Ndezvipi zviratidzo zvikuru zvekuneta uye kushanduka kwe diaphragm, uye zvinogona kuonekwa sei?
Kuverengwa kwekumanikidzwa kusina kurongeka, mhinduro dze sensor dzinononoka, uye kuyerera zvishoma nezvishoma kwebaseline zvinowanzo ratidza zviratidzo zvekuneta kwe diaphragm. Matambudziko aya anogona kukonzerwa nekumanikidzwa kwemagetsi kakawanda, mhedzisiro yekukwegura kwemvura, kana zviitiko zvekumanikidzwa kwenguva refu. Masisitimu epamusoro ekutarisa ari mukati haangotaridzi chete kutsauka kwekutanga kubva pakushanda kwakajairika asiwo anotanga nyevero dzezviitiko zvemaitiro ekugadzirisa panzvimbo. Kuonekwa kwekutanga kunoita kuti vashandi vagone kuronga kuongororwa kwakanangana, kutsiva zvikamu, uye kuongororwa kwekuchengetedza nguva refu diaphragm isati yakanganisa kuchengetedzeka kana kubereka kwemaitiro.
Ndezvipi zvimwe zvishandiso zviri mukati zvinobatsira mukuita kwese, uye nei?
Kutarisira zvinobudirira kwemaitiro echloralkali kunoda zvinopfuura kungova nedata rekumanikidzwa.Mita yekuyera mukati memutsetse, mamita ehuwandu kubva kuLonnmeter, mamita e viscosity, ma level transmitters, uye ma temperature transmitters zvese zvinobatsira mukuchengetedza uye kushanda zvakanaka kweprocess. Zvishandiso izvi pamwe chete zvinoongorora zvinhu zvakaita se fill fluid vaporization impact, mixed density, uye temperature drift. Vashandi vanogona kuona nekuderedza acid mhute condensation, kuona kuti corrosion inodzivirirwa zvakanaka pakati pegranular, uye kuderedza nguva yekusashanda isina kurongwa mu vaporization cycle yese.
