氨水又稱阿摩尼亞水，主要成分為NH3·H2O，是氨的水溶液，無色透明且具有刺激性氣味。氨氣熔點-77℃，沸點36℃，密度3。氨氣易溶于水、乙醇。易揮發(fā)，具有部分堿的通性，氨水由氨氣通入水中制得。氨氣有毒，對眼、鼻、皮膚有刺激性和腐蝕性，能使人窒息，空氣中更高容許濃度30mg/m3。氨水有一定的腐蝕作用，碳化氨水的腐蝕性更加嚴重。對銅的腐蝕比較強，鋼鐵比較差，對水泥腐蝕不大。氨水泵操作與作用：1.檢查電動機動轉的方向，是否與泵的旋轉標記一致。2.泵啟動前檢查托架油室內油位是否在規(guī)定范圍內，陜西酸堿泵生產。3.開啟進口閥門，往水泵內注足液體(引液)，陜西酸堿泵生產。4.關閉出口閥門。5.上述步聚完成后，啟動電機慢慢打開電機閥門，這時壓力表的位置將隨出水的大小和變化，陜西酸堿泵生產，當壓力表指針指到需要的位置時，停止對閥門的調整。6.當需要停車時，首先關閉出水閥門，切斷電源，再關閉進口閥門。氟塑料泵哪家服務好，上海原孚泵業(yè)為您服務！歡迎各位新老朋友垂詢！陜西酸堿泵生產</p><div

a.徑向接觸式輔助密封徑向接觸式輔助密封包括動環(huán)密封圈和靜環(huán)密封圈，它們分別構成動環(huán)與軸、靜環(huán)與端蓋之間的密封。同時，由于密封圈材料具有彈性，能對密封環(huán)起彈性支承作用，并對密封端面的歪斜和軸的振動有一定的補償和吸振效果，可提高密封端面的貼合度。當端面磨損后，在彈性力作用下，密封圈隨補償環(huán)沿軸向作微小的補償移動。重慶氟塑料離心泵哪家好氟塑料離心泵哪家專業(yè)，上海原孚泵業(yè)值得信賴，歡迎有需求的朋友們聯系我司！</p><div

機械密封結構形式分析1、離心泵動環(huán)的結構形式動環(huán)常用的結構。(a)比較簡單，省略了推環(huán)，適合采用橡膠O形輔助密封圈，缺點是密封圈溝槽直徑不易測量，使加工與維修不便;(b)對于各種形狀的輔助密封圈都能適應，裝拆方便，且容易找出因密封圈尺寸不合適而發(fā)生泄漏的原因;(c)只適合用0形密封圈，對密封圈尺寸精度要求低，容易密封，但密封圈易變形.為鑲嵌式結構，這種結構是將密封端面做成矩形截面的環(huán)狀零件(稱為動環(huán))，鑲嵌在金屬環(huán)座內(稱為動環(huán)座)，從而可節(jié)約貴重金屬。(d)為采用壓裝和熱裝的剛性過盈鑲嵌結構，加工簡便，但由于動環(huán)與動環(huán)座材料的線脹系數不同，高溫時易脫落，一般使用于軸徑小于100mm、使用壓力小于5MPa、密封端面平均線速度小于20m/s的場合。(e)為柔性過盈鑲嵌結構，其徑向不與動環(huán)座接觸，而是支承在柔性的輔助密封圈上，并采用柱銷連接，從而克服(d)的缺點，但加工困難，在標準型機械密封中很少采用。 </p>各種靜環(huán)支承方式 <p> a.浮動式靜環(huán)靠柔性件(如0形圈等)的壓縮變形支承在密封腔體上，并允許軸向和徑向略作浮動0密封要求嚴格時，可安裝兩道密封。高黏度介質和高壓、高速條件下應設置防轉銷。浮動式支承方式結構簡單，拆裝方便，能吸收部分軸和腔體的振動。但柔性體把靜環(huán)隔離，不利于熱傳導。 </p> <p> b.緊固式靜環(huán)靠機械方法支承。結構簡單，傳熱好，但不能吸收腔體振動。 </p> <p> c.鑲裝式靜環(huán)過盈配合在密封腔體上。結構簡單，傳熱好。但配合部位精度和粗糙度要求高，不能吸收腔體的振動，端面磨損后不易更換。 </p> <p> d.離心泵軸向定位式靜環(huán)由密封腔體定位，靠柔性件的壓縮變形支承0密封要求嚴格時，可安裝兩道密封。高黏度介質和高壓、高速條件下，應設置防轉銷。軸向定位式結構簡單，拆裝方便，傳熱好，但不能吸收腔體軸向振動。襯氟磁力泵選哪家，上海原孚泵業(yè)為您服務！有需求的不要錯過哦！</p><div style="width:100%;text-align: center;"><img

化工泵電動機維修技術介紹化工領域中，化工泵的使用很普遍，電動機是化工泵常用簡介方便的動力配置，電動機在使用中出現故障是難免的，電動機運行過程中發(fā)生故障時，該怎么檢查維修呢?一、電動機維修技巧——聽電動機正常運行時應發(fā)出均勻且較輕的"嗡嗡"聲，無雜音和特別的聲音。若發(fā)出噪聲太大，包括電磁噪聲、軸承雜音、通風噪聲、機械摩擦聲等，均可能是故障先兆或故障現象。1、對于電磁噪聲，如果電動機發(fā)出忽高忽低且沉重的聲音，則原因可能有以下幾種。(1)定子與轉子間氣隙不均勻，此時聲音忽高忽低且高低音間隔時間不變，這是軸承磨損從而使定子與轉子不同心所致。(2)三相電流不平衡。這是三相繞組存在誤接地、短路或接觸不良等原因，若聲音很沉悶則說明電動機嚴重過載或缺相運行。(3)鐵芯松動。電動機在運行中因振動而使鐵芯固定螺栓松動造成鐵芯硅鋼片松動，發(fā)出噪聲。襯氟磁力泵選哪家，上海原孚泵業(yè)為您服務！歡迎各位新老朋友垂詢！陜西酸堿泵生產</p><p

化工泵電動機維修技巧——看觀察電動機運行過程中有無異常，其主要表現為以下幾種情況。1.定子繞組短路時，可能會看到電動機冒煙。2.電動機嚴重過載或缺相運行時，轉速會變慢且有較沉重的"嗡嗡"聲。3.電動機正常運行，但突然停止時，會看到接線松脫處冒火花;保險絲熔斷或某部件被卡住等現象。4.若電動機劇烈振動，則可能是傳動裝置被卡住或電動機固定不良、底腳螺栓松動等。5.若電動機內接觸點和連接處有變色、燒痕和煙跡等，則說明可能有局部過熱、導體連接處接觸不良或繞組燒毀等。三、電動機維修技巧——聞通過聞電動機的氣味也能判斷及預防故障。若發(fā)現有特殊的油漆味，說明電動機內部溫度過高;若發(fā)現有很重的糊味或焦臭味，則可能是絕緣層被擊穿或繞組已燒毀。陜西酸堿泵生產</p><p
