Electromagnetic flowmeter chiridzwa chinoshandisa musimboti weelectromagnetic induction kuyera kuyerera kweconductive fluid zvichibva pamagetsi emagetsi anokonzereswa kana conductive fluid ichipfuura nekunze kwemagineti.
Saka sei kusarudza yemukati lining uye electrode zvinhu?
Lining Material Selection
■ Neoprene (CR):
A polymer inoumbwa ne emulsion polymerization ye chloroprene monomer. Iri molecule rerabha rine maatomu eklorini, saka zvichienzaniswa nemamwe rabha-chinangwa: Iine anti-oxidation, anti-ozone, isingabatike, inodzima moto mushure memoto, kuramba kwemafuta, kunyungudika, asidhi uye alkali kuramba, uye kuchembera. uye gasi kuramba. Good tightness uye zvimwe zvakanakira.
✔ Inokodzera kuyerwa kuyerwa kwepombi yemvura, mvura yeindasitiri, mvura yegungwa uye mamwe midhiya.
■ Polyurethane rabha (PU):
Iyo yakagadzirwa nepolyester (kana polyether) uye diisocyanamide lipid compound. Iine zvakanakira kuomarara kwepamusoro, simba rakanaka, kukwirira kwepamusoro, kukwirira kupfeka kusagadzikana, kusanzwa kwemisodzi, kuramba kuchembera, kuramba kwe ozone, kuramba kwemwaranzi uye kunaka kwemagetsi conductivity.
✔ Inokodzera kuyerwa kuyerwa kwe slurry media senge pulp uye ore pulp.
■Polytetrafluoroethylene (P4-PTFE)
Iyo polymer yakagadzirwa ne polymerization ye tetrafluoroethylene se monomer. White waxy, translucent, heat resistance, cold resistance, inogona kushandiswa mu -180 ~ 260°C kwenguva refu. Nyaya iyi ine hunhu hweasidhi uye alkali kuramba, kuramba kune akasiyana organic solvents, kuramba kufashaira hydrochloric acid, sulfuric acid, aqua regia, concentrated alkali corrosion.
✔ Inogona kushandiswa kune corrosive acid uye alkali munyu mvura.
■Polyperfluoroethylene propylene (F46-FEP)
Iyo ine yakanakisa kugadzikana kwemakemikari uye yakasarudzika radiation kuramba, pamwe nekusapisa moto, yakanaka magetsi uye michina zvinhu. Mishonga yaro yemakemikari yakaenzana ne polytetrafluoroethylene, ine simba rakasimba rekumanikidzika uye kusimba simba riri nani pane polytetrafluoroethylene.
✔ Inogona kushandiswa kune corrosive acid uye alkali munyu mvura.
■Copolymer ye tetrafluoroethylene uye perfluorocarbon kuburikidza nevinyl ether (PFA)
Iyo lining material ye electromagnetic flowmeter ine yakafanana kemikari zvivakwa seF46 uye zviri nani tensile simba pane F46.
✔Inogona kushandiswa kune corrosive acid uye alkali munyu mvura.
Electrode Material Selection
| 316L | Inokodzera tsvina yemumba, tsvina yemumaindasitiri, mvura yemutsime, tsvina yemudhorobha, nezvimwewo, uye isina kusimba inoodza acid-base munyu mhinduro. |
| Hastelloy (HB) | Inokodzera kwete-oxidizing acids yakadai sehydrochloric acid (concentration isingasviki 10%). Sodium hydroxide (concentration isingasviki 50%) sodium hydroxide alkali solution yezvese zvakadzika. Phosphoric acid kana organic acid, nezvimwewo, asi nitric acid haina kukodzera. |
| Hastelloy (HC) | Yakasanganiswa asidhi uye yakasanganiswa mhinduro yechromic acid uye sulfuric acid. Oxidizing salts yakadai seFe +++, Cu ++, mvura yegungwa, phosphoric acid, organic acids, nezvimwewo, asi isina kukodzera hydrochloric acid. |
| Titanium (Ti) | Inoshanda kune chlorides (yakadai se sodium chloride/magnesium chloride/calcium chloride/ferric chloride/ammonium chloride/aluminium chloride, nezvimwewo), munyu (senge sodium munyu, ammonium munyu, hypofluorite, potassium munyu, mvura yegungwa) , nitric acid (asi kwete kusanganisira fuming nitric acid), alkali ine concentration ≤50% patembiricha yekamuri (potassium hydroxide, sodium hydroxide, barium hydroxide, etc.) asi isingashande kune: hydrochloric acid, sulfuric acid, phosphoric acid, hydrofluoric acid, nezvimwe. |
| Tantalum electrode (Ta) | Inokodzera hydrochloric acid (concentration ≤ 40%), dilute sulfuric acid uye concentrated sulfuric acid (kunze kwefuming nitric acid). Inoshanda kune chlorine dioxide, ferric chloride, hypofluorous acid, hydrobromic acid, sodium cyanide, lead acetate, nitric acid (kusanganisira fuming nitric acid) uye aqua regia ine tembiricha yakaderera kupfuura 80°C. Asi iyi electrode zvinhu hazvina kukodzera alkali, hydrofluoric acid, mvura. |
| Platinum electrode (Pt) | Inoshanda kune dzinenge dzese acid-base salt solutions (kusanganisira fuming nitric acid, fuming sulfuric acid), isingashande kune: aqua regia, ammonia munyu, hydrogen peroxide, concentrated hydrochloric acid (>15%). |
Zviri pamusoro apa ndezvekutarisa chete, ndapota tarisa kune chaiyo bvunzo. Zvechokwadi, unogonawo kutibvunza. Tichakupa mamwe mazano.
Kambani yedu inogadzirawo zvimedu zvezviridzwa zvine hukama, zvinosanganisira maelectrodes, simbi diaphragms, mhete dzekudzika, diaphragm flanges, nezvimwe.
