定轉子過早磨損Premature wear of fixed rotor定轉子過早磨損主要是由于定轉子的間隙過小引起的。The premature wear of the fixed rotor is mainly caused by the small gap between the fixed rotor and the rotor.油管與抽油桿柱磨損Oil pipe and rod string wear油管與抽油桿柱磨損的原因一是因為井斜抽油桿貼在油管壁上引起的，可以通過加抽油桿扶正器使抽油桿柱居中來減輕或消除，另一個原因是定轉子不同心及轉子的偏心運動造成的，在定子以上加一節內徑較大的回轉筒即可避免。Tubing and sucker rod wear reason is because the deviation of sucker rod attached to the tubing wall caused by heating, pumping rod centralizer make the rod center to reduce or eliminate, another reason is caused by the eccentric motion of the rotor and the rotor are not concentric, avoid a day the diameter of rotary cylinder in the stator can be larger than.



Ｆ、抽油桿F, sucker rod所使用的抽油桿是常用的普通抽油桿、空心抽油桿和連續抽油桿，可根據油井確定。The sucker rod used is commonly used as a common 1sucker rod, hollow sucker rod and continuous sucker rod, which can be determined according to the oil well.Ｇ、定子扶正器G, stator centralizer定子扶正器為有一定彈性的籠形裝罩，每一對由兩半構成，中間大、兩端小。作用是使定子居中和減小定子的擺動。The stator centralizer is a cage shaped cover with a certain elasticity. Each pair is made up of two halves, large in the middle and small at both ends. The function is to make the stator middle and reduce the stator wobble.Ｈ、錨定裝置H, anchoring device對于沒有封隔器的井和泵掛深度淺的井，用于固定定子、消除擺動和防止定子脫扣。采用普通的錨定裝置即可。For wells without packers and shallow wells with deep pumps, it is used to fix the stator, eliminate the swinging and prevent the tripping of the stator. A common anchoring device can be used.



G型單螺桿泵型號在加熱爐燃燒系統中的應用 　　目前,有些中小型鋼鐵廠和其它冶金加工廠在沒有氣體燃料(如煤氣)的條件下,仍在使用液體燃料。而液體燃料為廣泛采用的是重油。比如加熱爐燃燒系統在重油的輸送及噴燃過程中,選擇合適的泵機組對爐子的正常工作很重要。由于重油的正常工作粘度一般都比較高(80 ℃時在50×102-6m2/s以上) ,而且隨著溫度的變化,其粘度的變化比較大。這就要求我們應該選擇合適的泵種以適應這些介質的輸送,使之穩定而無故障地運行。尤其是重油的噴燃,泵機組輸送壓力的恒定很重要。根據調查發現,目前采用外嚙合齒輪泵(稱齒輪泵)的用戶仍居多。其實在這些系統中如果采用G型單螺桿泵則是有更多優點。
