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。陜西四氟泵品牌氟塑料離心泵哪家專業(yè)，上海原孚泵業(yè)值得信賴，期待您的光臨！</p><div

</p><p> 耐酸堿襯氟自吸泵的性能調節(jié)，通常采用兩種方法1、變角調節(jié)從構造來看，自吸泵葉輪具有巨大的輪轂，便于安裝可調角度的葉片。當葉片安裝角度改變后，葉片對水的升力也就改變了，從而改變了水泵的工作性能，這就是自吸泵的變角調節(jié)。隨著葉片安裝角的增大、變小，自吸泵的流量、揚程、功率即隨之而變，但是，效率高點卻沒有什么變化，極有利于自吸泵性能調節(jié)。2、變速調節(jié)我們已經知道，自吸泵是在一定轉速下工作的，而且獲得相應的流量、揚程、功率和效率等。當轉速改變后，它的性能參數也相應地發(fā)生變化，從而達到調節(jié)的目的。如果自吸泵是采用柴油機或汽油機作動力的，可改變油門大小來變速;如果自吸泵與動力機相聯是采用三角皮帶或平皮帶間接傳動裝置的，則可以改變傳動皮帶輪直徑來變速，更換主動輪或從動輪都可以，目的是改變傳動速比。變速調節(jié)水泵性能，比較經濟，適用范圍較廣，對所有農用水泵均能采用。氟塑料磁力泵選哪家，上海原孚泵業(yè)為您服務！相信您的選擇，值得信賴。</p><div

汽蝕的產生原理汽蝕是一種液體動力學現象，發(fā)生的根本原因在于液體在流動過程中出現了局部壓力降，形成了低壓區(qū)。根據物理學知識可以知道，對于某種液相介質，在一定溫度下對應著一定的飽和蒸汽壓Pv，當介質的壓力小于Pv時就會發(fā)生汽化。離心泵運轉時，介質進入泵吸入口后，在葉輪沒有對介質做功前，壓力是逐漸降低的，當壓力降低到該處相應溫度下的飽和蒸汽壓時，介質就會沸騰汽化，使原來流動的介質出現大量的氣泡，氣泡中包含著輸送介質的蒸汽以及原來溶解在介質中而逸出的空氣。當氣泡隨同液流從低壓區(qū)流向高壓區(qū)時，由于轉動的葉輪對介質做功，介質壓力迅速上升，當壓力大于該處相應溫度下的飽和蒸汽壓Pv時，氣泡又會重新凝結成為液相，瞬間形成大量的空穴，而周圍的液相介質以高速沖向空穴相互撞擊，使得空穴處的局部壓力陡增。這種液擊是一種**度、高頻率的沖擊，其壓力可達數百個大氣壓以上，水擊頻率高達25000次/秒，材料壁面上因受到如此高頻率、高壓力的重復載荷作用而逐漸產生疲勞破壞。氟塑料化工泵哪家好，上海原孚泵業(yè)值得信賴，有需求的不要錯過哦！貴州氟塑料離心泵生產</p><p
