3分鐘前 莫諾螺桿泵配件來電垂詢 武漢螺耐斯[螺耐斯10e361c]內容：管柱脫落是自由式管柱結構經常發生的一種現象，這是由于正常運轉時轉子旋轉對定子產生的摩擦扭矩方向實際上是定子及油管的連接螺紋的卸扣方向，如果摩擦力矩大于油管扣的上扣扭矩，油管就脫扣。當尾管很重時，還會出現螺紋擄扣。當管柱脫落時，通過作業重新連接好就能恢復生產。如果未發生螺紋擄扣，可以采取對扣方式打撈，如果發生擄扣，必須下打撈工具進行打撈。Column shedding is a common phenomenon of free tube structure, which is due to the direction of rotation of the friction torque generated by the stator rotor during normal operation is actually a stator and tubing connection1 screw shackle direction, if the friction torque is greater than the pipe le on torque, oil pipe tripping. When the tail pipe is very heavy, there will also be a thread caption. When the pipe column falls off, the production can be restored by reconnecting the work. If the le is not threaded, it can be salvaged by the way of the le. If the le occurs, the fishing tool must be salvaged.

Ｅ、抽油桿扶正器E, sucker rod centralizer抽油桿扶正器由心軸和扶正筒組成，它接在兩根抽油桿之間，被卡在兩個抽油桿接箍之間。心軸也就是一要極短的抽油桿短節。扶正筒是一個內孔比心軸大１ＭＭ左右的空心塑料筒，外部有四個略比油管內徑小的扶正翼，采取澆注成型。扶正筒可以圍繞心軸轉動，防止抽油桿旋轉時與內壁接觸而磨蝕油管，又可以讓流體通過。The sucker rod centralizer is comed of the heart shaft and the upright cylinder, which is connected between the two sucker rods and is stuck between the two sucker rod hoops. The axis of the heart is also an extremely short rod short section. The centering cylinder is a hollow plastic tube inner hole Bixin shaft around 1MM, external four slightly smaller than the diameter of the tubing centralizer wing, adopt casting. The centralizer can revolve around the axis to pvent the sucker rod from touching the inner wall when it rotates, and it can also let the fluid pass through.

污泥輸送泵多用于排放粘度較高的輸送機械。利用葉輪的水利設計減少堵塞現象;軸和油室的密封緊密;安裝方便減少了操作的繁瑣，并且使用方便;易于維護。

污泥輸送泵不僅在生活中使用方便，使用壽命也長。在規定條件下，故障運行時間不小于10000h，整機使用壽命不小于20年。

污泥輸送泵的發展是因為其自身的技術特點及結構的合理，給我們帶來很大程度的方便。

1、單螺桿泵嚴禁在泵腔無液體的情況下空運轉，必須在啟動前由泵進口把液體注入泵體后再啟動螺桿泵，以免空轉磨損螺桿泵定子。

2、啟動單螺桿泵前還得必須先確定螺桿泵的運轉方向，螺桿泵不能反轉。

3、新安裝或長時間停泵數天后的單螺桿泵，不能立即起動，也應該向泵體注入適量潤滑劑或螺桿泵輸送的液體，再用管子鉗扳動螺桿泵幾轉后才可以起動。

4、不銹鋼螺桿泵輸送高粘度的液體或含有腐蝕性的介質后，應該用清水或者溶劑進行沖洗螺桿泵泵腔，防止堵塞以免造成下次起動螺桿泵時困難而損壞定子。

5、冬天使用單螺桿泵溫度偏低不使用時應該排除泵體積液，防止泵體凍裂或者泵內結冰下次起動時拉壞定子。

6、使用過程中軸承箱內應定期加潤滑油，發現軸端有滲流時，要及時處理或調換油封。

7、在運行中如發生異常情況，應立即停泵檢查原因，排除故障。
