Zviviri, Stainless steel valve rust solution Saka unoita sei kuti nzvimbo yesimbi igare yakapenya uye isina kuora? Sanjing Valve Manufacturing Co., LTD. Mazano evashandi vehunyanzvi nehunyanzvi: 1. Zvinodikanwa kuchenesa nekukwesha nzvimbo yekushongedza yesimbi isina tsvina nguva nenguva, kubvisa zvakanamatirwa uye kubvisa zvinhu zvekunze zvinokonzera shanduko. 2. Nzvimbo yegungwa inofanira kushandisa 316 simbi isina tsvina, 316 zvinhu zvinogona kudzivisa kuora kwemvura yegungwa. 3. Kuumbwa kwemakemikari emamwe machubhu esimbi asina tsvina pamusika haakwanisi kusangana nezvinodiwa nenyika, kusvika ku304 zvinhu zvinodiwa. Nokudaro, ichaitawo kuti iite ngura, iyo inoda kuti mushandisi anyatsosarudza chigadzirwa chekugadzirwa kwevagadziri vane mbiri uye nzvimbo dzekuvaka dzekutarisa kuitira kudzivirira kuvakwa kwezvikwepa uye zvinosvibisa zvakabatanidzwa, simbi isina tsvina yekuvaka pasi pemamiriro emufirimu. Asi nekuwedzera kwenguva, iyo yakasara paste fluid zvinoenderana nehupenyu hwebasa remufirimu, mushure mekuvakwa kwefirimu kunofanirwa kubviswa kana kugezwa kwepamusoro, uye kushandiswa kwemidziyo yesimbi isina tsvina, uye simbi yakawanda yekuchenesa maturusi eruzhinji, kuitira kuti usarega simbi yesimbi inonamatira inofanira kucheneswa. Kuchenjerera kunofanirwa kubhadharwa kudzivirira iyo inoparadza zvakanyanya magineti uye matombo emhando yepamusoro yekuchenesa mishonga kubva pakusangana nepamusoro pesimbi, kana kubata kuchifanira kugezwa ipapo. Mushure mekuvaka, detergent isina kwakare uye mvura inofanira kushandiswa kushambidza simenti, upfu uye madota zvakasungirirwa pamusoro.
