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.



Ｂ、轉子B, rotors轉子的結構也非常簡單，主體是鋼制桿件，一般外涂耐磨耐蝕的鉻合金材料。其作用是傳遞動力和寫定子形成密封腔。The structure of the rotor is also very simple, the main body is steel rod, generally coated with abrasion resistant and corrosion resistant chromium alloy material. Its function is to transfer power and write the stator to form a seal cavity.Ｃ、回轉筒C, rotary barrel回轉筒也就是一根內徑較大的油管或空心定子筒，接在定子的上部以給轉子和抽油桿桿柱以較大的回旋空間，防止轉子和抽油桿因偏心運動磨擦磨損油管。A rotary cylinder is also an oil tube or hollow stator barrel with larger inner diameter. It is connected to the upper part of the stator to provide larger swirl space for the rotor and sucker rod string, so as to prevent the rotor and sucker rod from attrition wear due to eccentric wear.

在使用一段時間的單螺桿泵吸不上液體很有可能是定子和轉子損壞所致，檢查更換新的定子或者轉子就可以了。    進出口管道上的閥門沒有打開或開度不夠，打開進出口閥門就可以了。    填料密封的單螺桿泵有可能是填料磨損、機械密封的螺桿泵有可能機械密封面損壞或磨損，壓緊或更換填料，機械密封損壞更換新的機械密封就可以了。

　G型單螺桿泵型號在我國20世紀50年代就已生產,近年來G型單螺桿泵型號技術及其應用發展較快。G型單螺桿泵型號屬于容積式泵,從結構上分:單螺桿泵、雙螺桿泵、三螺桿泵及船用螺桿泵。其中雙螺桿泵及三螺桿泵屬于典型的工業泵類,本文所述的螺桿泵就指的是這兩種泵。兩者的工作原理基本相同,使用場合相似,區別在于雙螺桿泵輸送的介質粘度范圍更寬些,且適用于非牛頓流體的輸送。兩者總效率相差不大,但雙螺桿泵的容積率略低于三螺桿泵。

211G型單螺桿泵可無脈動地工作 　　G型單螺桿泵工作時,通過螺桿轉子與泵套的孔壁間形成的一個個密封腔,平穩地從低壓區運送到高壓區,在整個運送過程中,介質作純軸向運動,可完全做到無脈動地運送介質。這一點與齒輪泵不同。齒輪泵工作時,在齒輪的轉動下,介質作軸向與徑向及其復合方向的運動,產生明顯的攪拌現象。其輸出壓力的表現形式:G型單螺桿泵的輸出壓力比較穩定,齒輪泵則出口壓力會有波動。這一點在輸送高粘度的介質(如重油等)時比較突出。
