Polytetrafluoroethylene (F4) yog cov yas uas muaj cov tshuaj lom neeg ruaj khov tshaj plaws. Nws yog resistant rau boiling hydrochloric acid, sulfuric acid, nitric acid thiab aqua regia, raws li zoo raws li concentrated alkali thiab ntau yam organic solvents. Tsis tiv taus corrosion los ntawm chlorine trifluoride, kub kub chlorine trifluoride, siab txaus tus nqi kua fluorine, kua oxygen thiab nws tus kheej-oxygen. 70 degree 100 degree 150 degree (kev txiav txim tshwj xeeb yuav tsum tau) 1. Muaj zog corrosive nruab nrab xws li concentrated acid thiab alkali. 2. Kev huv huv nruab nrab.
Polyperfluoroethylene propylene (F46) yog tib yam li F4, thiab nws hnav tsis kam thiab tsis zoo siab tsis kam yog siab dua F4. Ditto
Qhov ntsuas kub siab ntawm polyfluoroethylene (Fs) qis dua li ntawm polytetrafluoroethylene, tab sis tus nqi kuj tseem qis dua. 80 degree
Polychloroprene roj hmab 1. Nws muaj elasticity zoo heev, siab tawg quab yuam thiab hnav tsis kam. 2. Nws yog resistant rau corrosion ntawm feem ntau low-concentration acid, alkali, thiab ntsev media, thiab tsis resistant rau corrosion ntawm oxidizing media. 80 degree 120 degree (kev txiav txim tshwj xeeb yuav tsum tau) Dej, dej phwj tuaj, tsis muaj zog abrasive slurry.
Polyurethane roj hmab 1. Muaj zog hnav tsis kam.
2. Tsis zoo corrosion kuj. 80 degree Tsis tshua muaj thiab muaj zog abrasive slurries, thee slurries, thiab av nkos
Kev xaiv ntawm inlet tiv thaiv flange thiab grounding flange (los yog grounding nplhaib)
Flange Hom Muaj Scope
Grounding flanges (los yog grounding rings) yog tsim rau cov kav dej tsis siv, xws li cov kav dej yas, tab sis tsis tas yuav tsum muaj cov sensors nrog av electrodes.
Inlet tiv thaiv flange raug xaiv thaum nruab nrab muaj zog puas.

Cov khoom siv electrode Corrosion thiab hnav tsis kam
Stainless hlau 0Crl8Nil2M02Ti
Nws yog siv rau cov xov xwm tsis muaj zog corrosive xws li dej hauv tsev, dej hauv tsev, dej phwj tuaj, thiab lwm yam. Nws yog tsim rau kev lag luam sectors xws li roj av, tshuaj lom neeg kev lag luam, hlau thiab hlau, nrog rau hauv nroog, kev tiv thaiv ib puag ncig thiab lwm yam.
Hastelloy B
Nws muaj corrosion kuj zoo rau tag nrho cov concentrations ntawm hydrochloric acid hauv qab lub boiling point, thiab kuj yog resistant rau corrosion los ntawm non-chlorinated acids, alkalis thiab non-oxidative ntsev tov xws li sulfuric acid, phosphoric acid, hydrofluoric acid, thiab organic acids.
Hastelloy C
Nws yog resistant rau corrosion los ntawm non-oxidizing acids, xws li nitric acid, tov kua qaub, los yog tov khoom ntawm chromic acid thiab sulfuric acid, thiab kuj tiv taus corrosion los ntawm oxidizing ntsev xws li Fe, Cu los yog muaj lwm yam oxidants, xws li hypochlorite. siab tshaj qhov kub ib txwm Corrosion nyob rau hauv kev daws thiab dej hiav txwv
titanium
Nws yog resistant rau corrosion los ntawm seawater, ntau yam chlorides thiab hypochlorites, oxidizing acids (xws li oleum), organic acids thiab alkalis. Nws tsis tuaj yeem tiv taus corrosion ntawm cov kua qaub uas muaj kuab heev (xws li sulfuric acid, hydrochloric acid), tab sis yog tias cov kua qaub muaj oxidants (xws li nitric acid, Fc ntxiv, Cu ntxiv rau ntxiv), qhov corrosion yog heev txo.
Tantalum
Nws muaj kev tiv thaiv corrosion zoo heev thiab zoo ib yam li iav. Ntxiv nrog rau hydrofluoric acid, fuming sulfuric acid, thiab alkali, nws yuav luag tiv thaiv corrosion ntawm chemical media (xws li kub point hydrochloric acid, nitric acid thiab sulfuric acid hauv qab 150 degree). Diao hauv alkali; corrosion kuj.
Platinum / Titanium Alloy
Yuav luag resistant rau tshuaj media, tab sis tsis yog rau aqua regia thiab ammonium ntsev.
Stainless hlau coated tungsten carbide
Rau non-corrosive, heev abrasive media.
Lub electromagnetic flowmeter tsuas yog tsim los ntawm cov khoom ntws sensor transmitter.
Flow sensor converts lub ntim ntws ntawm cov kua conductive uas ntws los ntawm lub raj xa dej [3] mus rau hauv ib tug linear hluav taws xob teeb liab. Lub hauv paus ntsiab lus ntawm kev hloov dua siab tshiab yog qhov paub zoo Faraday txoj cai ntawm electromagnetic induction, uas yog, tus neeg xyuas pib dhau los ntawm qhov chaw sib nqus, txiav cov hlau electromagnetic, thiab ua kom muaj zog electromotive. Qhov sib nqus ntawm qhov ntws sensor yog paub los ntawm excitation, uas muab faib ua DC excitation, AC excitation thiab tsawg zaus square yoj excitation. Feem ntau cov flow sensors tam sim no siv tsawg zaus square wave excitation.
Lub transmitter yog tsim los ntawm excitation Circuit Court, teeb liab filtering thiab amplifying circuit, A / D sampling circuit, microprocessor circuit, D / A circuit, kis Circuit Court, thiab lwm yam.
Lub installation yuav tsum tau ntawmelectromagnetic flowmeteryog tias nws yuav tsum tau nruab rau ntawm qhov chaw qis tshaj ntawm cov kav dej lossis cov kab ntsug ntawm cov kav dej, tab sis nws yuav tsum yog nyob rau hauv rooj plaub ntawm cov kav dej tag nrho. kev siv thiab qhov raug.
