管柱脫落的故障現象是：運行電流很低，基本上是電機的空載電流，除了有一股一股的氣外，井口基本上無產液，正發循環時油套連通。The failure phenomenon of the string is: the running current is very low， basically the motor's no load current. Besides the gas with a single strand of gas， the wellhead basically has no liquid production，莫諾， and the oil sleeve is connected when circulating.減少管柱脫落的措施有：將油管上扣扭矩由原來的值提高到值；采用油管螺紋墊片；定子上的裝卸短節采用防松螺紋連接；采用油管錨或張力封隔器固定螺桿泵。The measures to reduce the falling off of the pipe string are as follows: increase the torque from the original value to the maximum value; use the oil pipe screw gasket; the loading and unloading joint on the stator is connected by loosening screw thread; and use the oil pipe anchor or tension packer to fix the screw pump.

　現將在現場采用同規格的G型單螺桿泵及齒輪泵在完全相同工況條件下并在輸送出口壓力為1 MPa時進行了簡單的對比，測量了這樣兩組數據:當輸送重油粘度約為75×102-6m2/ s時，齒輪泵出口壓力表的指針跳動幅度為±0.16，三螺桿泵出口壓力表的指針跳動幅度為±0.05，雙螺桿泵出口壓力表的指針跳動的幅度為±0.04 ;而當輸送重油粘度約為150×102-6m2/ s時，齒輪泵出口壓力表的指針跳動幅度為±0.22，三螺桿泵出口壓力表的指針跳動的幅度為±0.06，雙G型單螺桿泵出口壓力表的指針跳動的幅度為±0.04。這說明，G型單螺桿泵在重油的輸送和噴燃過程中，介質的輸送壓力很穩定。并且隨著介質粘度的加大，G型單螺桿泵(尤其是雙螺桿泵)的無脈動特點相比之下更為明顯。

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.
