管柱脫落的故障現(xiàn)象是：運(yùn)行電流很低，基本上是電機(jī)的空載電流，除了有一股一股的氣外，井口基本上無產(chǎn)液，正發(fā)循環(huán)時(shí)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(jié)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(xiàn)將在現(xiàn)場(chǎng)采用同規(guī)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(shí)進(jìn)行了簡(jiǎn)單的對(duì)比，測(cè)量了這樣兩組數(shù)據(jù):當(dāng)輸送重油粘度約為75×102-6m2/ s時(shí)，齒輪泵出口壓力表的指針跳動(dòng)幅度為±0.16，三螺桿泵出口壓力表的指針跳動(dòng)幅度為±0.05，雙螺桿泵出口壓力表的指針跳動(dòng)的幅度為±0.04 ;而當(dāng)輸送重油粘度約為150×102-6m2/ s時(shí)，齒輪泵出口壓力表的指針跳動(dòng)幅度為±0.22，三螺桿泵出口壓力表的指針跳動(dòng)的幅度為±0.06，雙G型單螺桿泵出口壓力表的指針跳動(dòng)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(zhì)的輸送壓力很穩(wěn)定。并且隨著介質(zhì)粘度的加大，G型單螺桿泵(尤其是雙螺桿泵)的無脈動(dòng)特點(diǎn)相比之下更為明顯。

Ｂ、轉(zhuǎn)子B， rotors轉(zhuǎn)子的結(jié)構(gòu)也非常簡(jiǎn)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(dòng)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(zhuǎn)筒C， rotary barrel回轉(zhuǎn)筒也就是一根內(nèi)徑較大的油管或空心定子筒，接在定子的上部以給轉(zhuǎn)子和抽油桿桿柱以較大的回旋空間，防止轉(zhuǎn)子和抽油桿因偏心運(yùn)動(dòng)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.
