動靜環(huán)密封面的泄漏，原因主要有：端面平面度，粗糙度未達到要求，或表面有劃傷；端面間有顆粒物質，造成兩端面不能同樣運行；安裝不到位，方式不正確。 </p> <p> 補償環(huán)密封圈泄漏，原因主要有：壓蓋變形，預緊力不均勻；安裝不正確；密封圈質量不符合標準；密封圈選型不對。 </p> <p> <br /> </p> <p> 液體介質潤滑性較差，加之操作壓力過載，兩密封面追蹤轉動不同步。例如高轉速泵轉速為20445r/min，密封面中心直徑為7cm，泵運轉后其線速度高達75 m/s，當有一個密封面滯后不能追蹤旋轉，瞬時高溫造成密封面損壞。 </p> <p> <br /> </p><p> 流量調節(jié) </p> <p> 改變閥門的開度 </p> <p> 改變離心泵出口管線上的閥門開關，其實質是改變管路特性曲線。如下圖所示，當閥門關小時，管路的局部阻力加大，管路特性曲線變陡，工作點由M移至M1，流量由QM減小到QM1。當閥門開大時，管路阻力減小，管路特性曲線變得平坦一些，工作點移至M2，流量加大到QM2。 </p> <p> 用閥門調節(jié)流量迅速方便，且流量可以連續(xù)變化，適合化工連續(xù)生產的特點。所以應用十分廣。缺點是閥門關小時，阻力損失加大，能量消耗增多，很不經濟。江蘇地區(qū)定做離心泵——靖江市瑞鑫泵業(yè)有限公司。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">上海離心泵——靖江市瑞鑫泵業(yè)有限公司。浙江工業(yè)離心泵功率</p><p> 泵體也稱泵殼，它是水泵的主體。起到支撐固定作用，并與安裝軸承的托架相連接。 </p> <p> 泵軸的作用是借聯軸器和電動機相連接，將電動機的轉矩傳給葉輪，所以它是傳遞機械能的主要部件。 </p> <p> 滑動軸承使用的是透明油作潤滑劑的，加油到油位線。太多油要沿泵軸滲出，太少軸承又要過熱燒壞造成事件！在水泵運行過程中軸承的溫度比較高在85度，一般運行在60度左右。 </p> <p> <br /> </p> <p> 密封環(huán)又稱減漏環(huán)。 </p> <p> 填料函主要由填料、水封環(huán)、填料筒、填料壓蓋、水封管組成。填料函的作用主要是為了封閉泵殼與泵軸之間的空隙，不讓泵內的水流流到外面來也不讓外面的空氣進入到泵內。始終保持水泵內的真空！當泵軸與填料摩擦產生熱量就要靠水封管住水到水封圈內使填料冷卻！保持水泵的正常運行。所以在水泵的運行巡回檢查過程中對填料函的檢查是特別要注意！在運行600個小時左右就要對填料進行更換。 </p> <p> <br
