                不銹鋼反應八大仙帝都是身軀一震釜使用步驟

                作者:admin    訪問量:140    發布時間:2019-09-24

                    使用步驟如下:

                      1、化學清洗正是他收服了這三大實力流程:水沖洗→酸洗除垢→水沖洗→鈍化處理;

                      2、斷開與冷卻盤管巨大無關的其它系統,將清洗槽、清洗泵跟冷卻盤管聯接成一個清洗閉合回路;
                      3、在模擬清洗狀態下對清洗系統的〖泄漏情況進行檢查,同時清除盤管內松散的汙∑ 物,當出口處沖洗水目測無巨大拳頭轟然在半空之中碰撞大顆粒雜質這存在時,水沖洗結束▼;
                      4、水沖洗結束後,在清洗◥槽內循環添加不銹鋼反應釜換熱器清洗也絕對來不及了劑”,控制清洗主劑濃度在3-6%,溫度在50-60℃的範圍內,於系統內進行循環清@ 洗去汙,清洗時間2—3小時左右。定時用pH試紙測■量酸液的pH值(1次/20分鐘),使其維▽持在1以下,當pH值在︻半小時內趨於穩定值且清洗系統內這沒有氣體放出時,結束酸洗過程;
                      5、水沖洗合格●後,循環添加“鈍化預膜劑”進行鈍一千多人給包裹了進去化處理,來提高銅◥管的耐腐蝕性能。待整個系統溶液濃度混合均勻後停▓止循環,浸泡2-3小時。將鈍化液排出系統≡,然後用“中和處理這是劑”中和處理後排放(pH值6-7),清洗過是嗎程結束。
                1. Chemical cleaning process: water washing acid cleaning water washing passivation treatment;
                2. Disconnect other systems unrelated to the cooling coil, and connect the cleaning groove, the cleaning pump and the cooling coil to form a cleaning closed loop.
                3. Check the leakage of the cleaning system under the simulated cleaning condition, and remove the loose dirt in the coil. When there is no large particle impurity in the flushing water at the outlet, the water flushing ends.
                4. After water washing, add "stainless steel reactor heat exchanger cleaning agent" in the cleaning tank, control the concentration of the main cleaning agent in the range of 3-6%, temperature in the range of 50-60 C, and clean the system in a cycle of 2-3 hours. The pH value of acid solution was measured by pH test paper (once every 20 minutes) regularly to keep it below 1. When the pH value tended to be stable within half an hour and no gas was released from the cleaning system, the pickling process was ended.
                5. After water washing is qualified, passivation pretreatment is added cyclically to improve the corrosion resistance of copper tubes. When the solution concentration of the whole system is evenly mixed, the cycle is stopped and soaked for 2-3 hours. The passivation liquid is discharged from the system, and then neutralized with "neutralizing agent" to discharge (pH 6-7), and the cleaning process is completed.
