Ndapota Ziva:

(1) EPDM gaskets haifanire kusangana neanonhuhwirira solvents kwehafu yeawa.

(2) Rutivi rwekuseri kwendiro haigoni kubata pasi zvakananga pakuchenesa.

(3) Mushure mekuchenesa mvura, nyatsotarisa mahwendefa uye gaskets uye hapana zvakasara zvakadai sezvimedu zvakasimba uye fiber dzakasiiwa pamusoro peplate inobvumirwa. Iyo yakabviswa uye yakakuvadzwa gasket ichanamirwa kana kutsiviwa.

(4) Paunenge uchigadzira mechanicha yekuchenesa, simbi brashi haitenderwe kushandisa kudzivirira kukwenya ndiro uye gasket.

(5) Paunenge uchichenesa nepfuti yemvura yakakwira, ndiro yakaoma kana ndiro yakasimbiswa inofanira kushandiswa kutsigira ndiro yekumashure (ndiro iyi ichabatwa zvizere nendiro yekutsinhanisa kupisa) kudzivirira kubva pakuparara, chinhambwe chiri pakati pemhino nekutsinhana. ndiro haifaniri kunge iri pasi pe200 mm, iyo max. jekiseni kudzvinyirirwa hakusi mukuru kupfuura 8Mpa; Zvichakadaro, kuunganidzwa kwemvura kunofanirwa kutarisisa kana uchishandisa pfuti yemvura yakakwira kudzivirira kusvibisa panzvimbo uye nemimwe michina.

2  Kemikari kuchenesa

Kune yakajairwa foiling, zvinoenderana nehunhu hwayo, alkali mumiririri ane mashoma mashoma kana akaenzana ne4% kana asidhi mumiriri ane mashoma mashoma kana akaenzana ne4% anogona kushandiswa kuchenesa, maitiro ekuchenesa ndeaya:

(1) Kuchenesa tembiricha:40 ~ 60℃.

(2) Kudzokera kumashure pasina disassembly yemidziyo.

a) Batanidza pombi pane media inlet uye pombi yekubuda pamberi;

b) Batanidza midziyo ne "mechanic yekuchenesa mota";

c) Pomba mhinduro yekuchenesa mumidziyo mukatarisana seyakajairika chigadzirwa chinoyerera;

d) Denderedzwa yekuchenesa mhinduro 10 ~ 15 maminetsi pa media flow rate ye 0.1～0.15m/s;

e) Pedzisiraizve tenderera 5～10 maminetsi nemvura yakachena. Chloride iri mumvura yakachena inofanira kuva isingasviki 25ppm.

Ndapota Ziva:

(1) Kana iyi nzira yekuchenesa ikagamuchirwa, iyo spare connection ichasara isati yasangana kuti mvura yekuchenesa ibude zvakanaka.

(2) Mvura yakachena ichashandiswa kugezesa mutsinhanisi wekupisa kana kufuratira kunoitwa.

(3) Yakakosha yekuchenesa mumiriri ichashandiswa kuchenesa tsvina yakasarudzika zvichienderana neayo kesi.

(4) Iyo mechanic uye makemikari yekuchenesa nzira inogona kushandiswa pamwe chete.

(5) Hazvina mhosva kuti ndeipi nzira inogamuchirwa, iyo hydrochloric acid haibvumirwi kuchenesa ndiro yesimbi isina tsvina. Mvura inodarika 25 ppm chlorion yemukati haigone kushandiswa kugadzira mvura yekuchenesa kana kupenengura ndiro yesimbi isina tsvina.
