Kudzivirira & Kurapwa kweButterfly Valve Corrosion

Chii chinonzi corrosionbutterfly mavharuvhu?

Kuora kwemavharuvhu e butterfly kunowanzo kunzwisiswa sekukuvadzwa kwesimbi yevharuvhu pasi pekuita kwemakemikari kana electrochemical nharaunda. Sezvo chiitiko che "corrosion" chinoitika mukubatana kunongoerekana kwaitika pakati pesimbi nenharaunda yakapoteredza, nzira yekuparadzanisa simbi kubva kune yakapoteredza nharaunda kana kushandisa zvimwe zvisiri-metallic synthetic zvinhu ndiyo inotarisa kudzivirira kuora. Muviri webutterfly valve(kusanganisira chivharo chevhavha) inotora huwandu hwehuremu hwevhavha uye inowanzosangana nepakati, saka valve butterfly inowanzosarudzwa kubva kumuviri wenyama.

Kune nzira mbiri chete dzevharuvhu muviri corrosion yebutterfly mavharuvhu, kureva kemikari corrosion uye electrochemical corrosion. Mwero wekuora kwayo unotarwa netembiricha, kudzvanywa, makemikari zvimiro zvepakati, uye kushora kwekudzivirira kwevhavha yemuviri zvinhu. Iyo corrosion rate inogona kukamurwa kuita matanhatu:

1. Complete corrosion resistance: chiyero chekuora chiri pasi pe 0.001 mm / gore;

2. Kunyanya kusagadzikana kwekuora: chiyero chekuora 0.001-0.01 mm / gore;

3. Corrosion resistance: chiyero chekuora 0.01-0.1 mm / gore;

4. Kurwisana kwepamusoro-soro: chiyero chekuora 0.1-1.0 mm / gore;

5. Kusagadzikana kwehuturo: chiyero chekuora 1.0-10 mm / gore;

6. Non-corrosion resistance: chiyero chekuora chinodarika 10 mm / gore.

Nzira yekudzivirira ngura yebutterfly mavharuvhu?

Iyo Anti-Corrosion yeValve Muviri weButterfly Valve inonyanya kukonzerwa nekusarudzwa kwakakodzera kwemidziyo. Kunyange zvazvo ruzivo rwe-anti-corrosion rwakapfuma kwazvo, hazvisi nyore kusarudza iyo yakarurama, nokuti dambudziko rekuora rakanyanya kuoma, semuenzaniso, sulfuric acid inotyisa zvikuru kune simbi kana kusungirirwa kwakaderera, uye kana kusungirirwa kwakakwirira, kunoita kuti simbi ibudise firimu ye passivation, iyo inogona kudzivirira kuparara; Hydrogen inongoratidzwa kuva inoparadza zvakanyanya kune simbi pakupisa kwepamusoro uye kumanikidzika, uye kushanda kwegorosi kwegesi yeklorini haisi yakakura kana yakaoma, asi kushanda kwehutu kunonyanya kusimba kana pane humwe hunyoro, uye zvinhu zvakawanda hazvigone kushandiswa. Kuoma kwekusarudza zvinhu zvemuviri wevhavha ndeyokuti hatigoni kungofunga nezvematambudziko ekuora, asiwo funga zvinhu zvakadai sekumanikidzika uye kupisa kwekushisa, zvingave zvine hupfumi, uye kana zviri nyore kutenga. Saka unofanira kungwarira.

1. Chechipiri ndechekutora matanho ekugadzira, akadai semutobvu, aluminium, mapurasitiki einjiniya, rabha rechisikigo uye rakasiyana siyana rekugadzira rabha. Kana mamiriro epakati achibvumidza, iyi inzira yekuchengetedza.

2. Chechitatu, kana kudzvinyirirwa uye kutonhora kusina kukwirira, chinhu chikuru che fluorine-lined butterfly valve inogona kazhinji kubudirira zvikuru mukudzivirira kuora.

3. Mukuwedzera, kunze kwemuviri wevhavha inosvibiswawo nemhepo, uye ductile iron material inowanzochengetedzwa ne nickel plating.

TWS ichakurumidza kuburitsa mutsara mutsva we-anti-corrosion product, unovhara huwandu hwakazara hwemhinduro dzevharuvhu sengebutterfly mavharuvhu, gedhi mavharuvhu, cheki mavharuvhuuye mavharuvhu ebhora, nezvimwewo. Iyi nhevedzano yezvigadzirwa inotora advanced corrosion resistance tekinoroji uye akakosha ekurapa maitiro ekuchengeta yakanakisa yekuisa chisimbiso kuita uye kugadzikana kwekushanda pasi pemamiriro ekushanda akanyanya. Isu takazvipira kupa vatengi zvigadzirwa zvinogara zvemaindasitiri mavharuvhu, zvakanyanya kuwedzera hupenyu hwesevhisi yemidziyo, kuderedza mari yekuchengetedza hupenyu hwese.spankutenderera, uye kubatsira vatengi kuwana yakakwirira kukosha kwekutenga sarudzo.
